Description

Technical Field

[0001] This invention relates to coating equipment, and more particularly to a multi-surface automated coating equipment. Background Technology

[0002] With the widespread adoption of smart devices, smartwatches are becoming increasingly common. To facilitate display, a significant proportion of smartwatches adopt a square shape. To enhance comfort and appearance, the corners on the back of the watch case are rounded, and the surface undergoes electroplating or other finishing processes. During assembly and transportation, a protective film is typically applied to the watch case surface to prevent scratches. However, due to the complex curvature and multiple surfaces of the watch case, traditional contour-following film application heads struggle to achieve precise application, leading to film misalignment or air bubbles at the application point. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide an automated multi-surface film application device.

[0004] The technical solution adopted by this invention to solve its technical problem is: a multi-surface automated film application device, comprising:

The second film-picking pre-pressure head and the second film-picking pre-pressure cylinder slide vertically together, and a buffer spring is connected between the second film-picking pre-pressure head and the second film-picking pre-pressure cylinder.

[0017] As a further improvement to this design, both the first film picking mechanism and the second film picking mechanism further include a film edge repressing mechanism. The film edge repressing mechanism includes two oppositely arranged edge repressing cylinders and an edge repressing head disposed on the edge repressing cylinders. The translation path of the edge repressing head is perpendicular to the axis of the first film picking rod or the axis of the second film picking rod. The opposite side of the repressing head is provided with an edge contour surface that matches the edge of the watch case where the film is picked.

[0019] As a further improvement to this design, the watch case positioning platform includes a watch case positioning block and a watch case positioning pin disposed at the top center of the watch case positioning block. The watch case positioning pin has three pins arranged in a circular array around the central hole of the watch case. The top surface of the watch case positioning block has a positioning surface that fits into the inner cavity of the watch case. The workstation turntable assembly has a bottom film support assembly that corresponds one-to-one with the watch case positioning platform. The bottom film support assembly includes a top film column that is slidably connected to the indexing turntable and a top film cylinder disposed on the machine platform. The top of the top film column is located below the edge of the film material. The top film cylinder has a top film block located below the top film column.

[0020] As a further improvement to this design, the machine tool is also equipped with a transfer assembly, which includes a watch case transfer slide rail mounted on the machine tool, a watch case transfer translation cylinder mounted on the machine tool, a watch case transfer slide block that slides with the watch case transfer slide rail, a watch case transfer take-up and put-down cylinder mounted on the watch case transfer slide block, a transfer three-claw cylinder mounted on the watch case transfer take-up and put-down cylinder, a transfer positioning ring elastically connected to the transfer three-claw cylinder, and a secondary positioning stage mounted on the machine tool.

The bottom of the top surface repressing block is provided with a top surface contour surface that fits against the top surface and upper edge of the watch case. The four-corner repressing assembly includes four-corner repressing cylinders that correspond one-to-one with the four corners of the watch case, and four-corner repressing blocks mounted on the four-corner repressing cylinders. The four-corner repressing blocks are provided with four-corner contour surfaces that fit against the corners of the watch case on the side facing the corners of the watch case.

[0022] The beneficial effects of this invention are as follows: This invention uses two rolling edge-wrapping components to roll the film material on the watch case in steps. The outward-opening rolling rollers facilitate rolling the film material from the center to the edge, resulting in good film material adhesion. The rolling gripper cylinder facilitates disengagement from the film material during the rolling process, preventing damage to the film material. The contouring side pressure block can reshape and re-press the edge of the watch after film application, improving the adhesion of the film material edge. The first and second film-picking mechanisms separate the bottom film of the film material on two opposite sides of the watch case, facilitating the subsequent peeling mechanism to remove the bottom film. The entire process is automated, improving production efficiency. Attached Figure Description

[0040] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0041] Example: A multi-surface automated film application device, comprising:

[0042] 10 machines;

[0043] The workstation turntable assembly 2 includes an indexing turntable 20 and watch case positioning platforms 21 arranged in a ring array on the edge of the top surface of the indexing turntable 20.

[0044] The film application assembly 3 includes a film application triaxial module 30 and a vacuum film application head 31 disposed on the film application triaxial module 30. The bottom of the vacuum film application head 31 is provided with a film application vacuum hole for adsorbing film material (not shown in the figure).

[0045] The rolling and binding assembly 4 includes a rolling frame 40, a rolling lifting cylinder 45 mounted on the rolling frame 40, a rolling gripper cylinder 44 mounted on the rolling lifting cylinder 45, a rolling block 43 mounted on the gripper of the rolling gripper cylinder 44, a rolling swing arm 42 hinged at one end to the rolling block 43, a rolling wheel 41 rotatably connected to the bottom of the rolling swing arm 42, side push cylinders 46 located on both sides of the rolling gripper cylinder 44, and a contoured side pressure block 47 mounted on the side push cylinder 46. To improve the rolling effect of the rolling wheel 41, the rolling wheel 41 is a rubber-coated wheel. Each rolling block 43 is hinged with two parallel rolling swing arms 42. The two ends of the rolling wheel 41 are rotatably connected to the rolling swing arms 42, which improves the force on the rolling wheel 41 and enhances the rolling effect of the rolling wheel 41. The contoured side pressure block 47 has a contoured surface that fits into the edge of the watch case, and the surface of the contoured surface is covered with soft rubber, such as silicone, to improve the adhesion to the film material, prevent scratches on the film material, and play a buffering role during repressurization to reduce impact damage to the watch case.

[0046] The first film-picking mechanism 5 includes a first film-picking base 50, a first film-picking avoidance cylinder 51 disposed on the first film-picking base 50, and two first film-picking rods 55 disposed on the first film-picking avoidance cylinder 51. The two first film-picking rods 55 rotate around the folded edge of the film material. The first film-picking rods 55 are driven by a rotary cylinder. The hardness of the bottom film is greater than that of the bonding film material. After the bonding film material is bonded to the watch case, the bottom film separates from the bonding film material due to its own reset. The rotation path of the first film-picking rods 55 passes through the edge of the bottom film and picks the bottom film upward, causing the bottom film to separate from the bonding film material.

[0047] The second film-picking mechanism 6 includes a second film-picking base 60, a second film-picking avoidance cylinder 61 disposed on the second film-picking base 60, a second film-picking lifting cylinder 62 disposed on the second film-picking avoidance cylinder 61, and two second film-picking rods 63 disposed on the second film-picking lifting cylinder 62. The two second film-picking rods 63 rotate around the folded edge of the film material. The second film-picking rods 63 are still driven by a rotary cylinder.

[0048] The film-tearing mechanism 7 includes a film-tearing linear module 73 mounted on the machine base 10, a film-tearing lifting module 72 mounted on the film-tearing linear module 73, a film-tearing gripper mechanism 71 mounted on the film-tearing lifting module 72, and a waste film collection box 70 mounted on the machine base 10. The film-tearing gripper mechanism 71 includes a film-tearing rotary cylinder 711 and a film-tearing gripper cylinder 710 mounted on the film-tearing rotary cylinder 711. The gripper surface of the film-tearing gripper cylinder 710 is made of a non-stick material to the bottom film, and the rotation axis of the film-tearing rotary cylinder 711 is horizontal. The film-tearing mechanism 7 also includes a film-drawing fan 76 mounted at the opening of the waste film collection box 70 and an ion fan 77 mounted on the machine base 10. The ion fan 77 eliminates static electricity on the bottom film, facilitating the film-drawing fan 76 to draw the bottom film from the film-tearing gripper cylinder 710. To prevent tangling, the film-drawing fan 76 is a bladeless fan.

[0049] The machine 10 is equipped with two rolling edge binding assemblies 4. The first film picking mechanism 5 is located at the station after the first rolling edge binding assembly 4, and the second film picking mechanism 6 is located at the station after the second rolling edge binding assembly 4.

[0050] The above-mentioned two rolling edge-wrapping components 4 roll the film material on the watch case in steps. The outward-opening rolling rollers 41 facilitate rolling the film material from the center to the edge, resulting in good film material adhesion. The rolling gripper cylinder 44 facilitates disengagement from the film material during the rolling swing arm 42 process, preventing damage to the film material. The contouring side pressure block 47 can reshape and re-press the edge of the watch after film application, improving the adhesion of the film material edge. The first film picking mechanism 5 and the second film picking mechanism 6 separate the bottom film of the film material on the two opposite sides of the watch case, which facilitates the subsequent peeling of the bottom film by the film peeling mechanism 7. The whole process is automated, improving production efficiency.

[0051] The machine 10 is equipped with a film feeding feeder 1 (purchased component) to achieve automatic film feeding. The vacuum film applicator 31 includes a film applicator rotary motor 310 mounted on the film applicator triaxial module 30, a film applicator fixing seat 311 mounted on the film applicator rotary motor 310, a film applicator slide 312 that slides up and down along the film applicator fixing seat 311, and an adsorption block 313 located at the bottom of the film applicator slide 312. The film applicator slide 312 is elastically connected to the film applicator fixing seat 311, and the film applicator vacuum hole is located on the adsorption block 313. The film applicator rotary motor 310 adjusts the angle of the film material to match the watch case, and the elastically slidable adsorption block 313 reduces the impact when picking up and placing the film material.

[0052] A return spring 48 is connected between the rolling arms 42, and the tension of the return spring 48 drives the two rolling arms 42 to move closer to each other. To ensure that the closing force of the rolling arms 42 is balanced, return springs 48 are usually provided on the rolling arms 42 at both ends of the rolling roller 41. The return spring 48 can also provide a certain amount of flexible pressure to the rolling roller 41, thereby improving the rolling effect.

[0053] The rolling lifting cylinder 45 is equipped with a pre-pressure head 49 that slides up and down. The pre-pressure head 49 is elastically connected to the rolling lifting cylinder 45 and is located between the rolling swing arms 42. The pre-pressure head 49 is located between the two rolling rollers 41 and presses against the film material before the rolling rollers 41 to ensure that the film material does not shift. The end of the pre-pressure head 49 is made of soft rubber, which plays a role in cushioning and shock absorption, preventing damage to the film material and watch case, and increasing friction.

[0054] The first film-picking base 50 is equipped with a first film-picking pre-pressure cylinder 52, and a first film-picking pre-pressure head 54 is connected to the first film-picking pre-pressure cylinder 52. The first film-picking pre-pressure head 54 has a first film-picking pre-pressure notch 540, and the side of the first film-picking pre-pressure notch 540 is in contact with the edge of the watch case perpendicular to the axis of the first film-picking rod 55. The first film-picking pre-pressure head 54 and the first film-picking pre-pressure cylinder 52 slide vertically together, and a buffer spring 53 is connected between the first film-picking pre-pressure head 54 and the first film-picking pre-pressure cylinder 52. The first film-picking pre-pressure head 54 facilitates pressing and limiting the adjacent film material when picking the bottom film of the first pair of sides, effectively preventing the bottom film of the first pair of sides from pulling the film material of the adjacent sides at the corner, thereby preventing the film material from peeling at the corner. The second film-picking mechanism 6 further includes a second film-picking pre-pressure cylinder 64, on which a second film-picking pre-pressure head 65 is connected. The second film-picking pre-pressure head 65 has a second film-picking pre-pressure notch 650, the side of which is perpendicular to the axis of the second film-picking rod 63 and fits against the edge of the watch case. The second film-picking pre-pressure head 65 and the second film-picking pre-pressure cylinder 64 slide vertically together, and a buffer spring 53 is connected between the second film-picking pre-pressure head 65 and the second film-picking pre-pressure cylinder 64. Similarly, the second film-picking pre-pressure head 65 facilitates pressing and limiting the adjacent film material when picking the bottom film of the second opposite side, effectively preventing the bottom film of the second opposite side from pulling the film material of the adjacent opposite side at the corner, thereby preventing the film material from peeling at the corner.

[0055] To prevent the bottom film from pulling on the bonding film during the film picking process, which could reduce the adhesion between the bonding film and the watch case, both the first film picking mechanism 5 and the second film picking mechanism 6 further include a film edge repressing mechanism 66. The film edge repressing mechanism 66 represses the edge of the bonding film after film picking. The film edge repressing mechanism 66 includes two opposing edge repressing cylinders 660 and an edge repressing head 661 mounted on the edge repressing cylinders 660. The translation path of the edge repressing head 661 is perpendicular to the axis of the first film picking rod 55 or the axis of the second film picking rod 63. The opposite side of the repressing head is provided with an edge contour surface 662 that matches the edge of the watch case where the film has been picked. To reduce scratches on the film and ensure a good repressing effect, the surface of the edge contour surface 662 is covered with a soft rubber layer.

[0056] To prevent the adhesive film from being peeled off due to the pulling of the bottom film during film removal, the film removal mechanism 7 also includes a film removal pre-pressure cylinder 75 and a film removal pre-pressure head 74 slidably connected to the film removal pre-pressure cylinder 75. The film removal pre-pressure head 74 abuts against the adhesive film at the edge of the watch case during film removal.

[0057] The watch case positioning platform 21 includes a watch case positioning block 211 and a watch case positioning pin 213 disposed at the top center of the watch case positioning block 211. Three watch case positioning pins 213 are arranged in a circular array around the central hole of the watch case. The top surface of the watch case positioning block 211 has a positioning surface 212 that fits into the inner cavity of the watch case. The watch case positioning pins 213 are vertically oriented cylinders, and the top of each pin has a guiding conical surface. The three circularly arrayed cylindrical watch case positioning pins 213 effectively guide and position the watch case, thus centering it.

[0058] The turntable assembly 2 at the workstation is equipped with a bottom film lifting assembly 210 corresponding to the watch case positioning platform 21. The bottom film lifting assembly 210 includes a top film column 2102 slidably connected to the indexing turntable 20 and a top film cylinder 2100 mounted on the machine base 10. The top of the top film column 2102 is located below the edge of the film material. A top film block 2101 is mounted on the top film cylinder 2100, located below the top film column 2102. The top film column 2102 lifts the bottom film upwards, facilitating the film-tearing gripper cylinder 710 to hold the bottom film. To facilitate the operation of the top film column 2102, its top end is spherical and made of a non-adhesive material. The top surface is used in both the first and second rolling film workstations to ensure that non-rolled film material is lifted, preventing accidental adhesion to the watch case surface.

[0059] To facilitate secondary positioning of the watch case before loading, the machine tool 10 is also equipped with a transfer assembly 12. The transfer assembly 12 includes a watch case transfer slide rail 124 mounted on the machine tool 10, a watch case transfer translation cylinder 120 mounted on the machine tool 10, a watch case transfer slide block 121 slidably engaged with the watch case transfer slide rail 124, a watch case transfer take-up and take-down cylinder 123 mounted on the watch case transfer slide block 121, a transfer three-claw cylinder 125 mounted on the watch case transfer take-up and take-down cylinder 123, a transfer positioning ring 126 elastically connected to the transfer three-claw cylinder 125, and a secondary positioning stage 122 mounted on the machine tool 10. The claws of the transfer three-claw cylinder 125 pass through the transfer positioning ring 126, and the watch case transfer translation cylinder 120 is connected to the watch case transfer slide block 121. The jaws of the transfer three-jaw cylinder 125 are cylindrical, which facilitates the centering and gripping of the watch case and prevents damage or contamination to the protective film surface of the watch case. The transfer positioning ring 126 facilitates the positioning of the watch case's bonding surface and allows the watch case to be pushed out of the transfer three-jaw cylinder 125 during unloading, preventing the watch case from tilting during unloading.

[0060] This equipment also includes a top surface repressing assembly 8 and a four-corner repressing assembly 9. The top surface repressing assembly 8 is located at the film-peeling station or a station behind the film-peeling station. The top surface repressing assembly 8 includes a top surface repressing frame 82, a top surface repressing cylinder 83 disposed on the top surface repressing frame 82, and a top surface repressing block 81 disposed on the top surface repressing cylinder 83. The bottom of the top surface repressing block 81 is provided with a top surface contouring surface 80 that fits against the top surface and upper edge of the watch case. The four-corner repressing assembly 9 includes four-corner repressing cylinders 90 that correspond one-to-one with the four corners of the watch case, and four-corner repressing blocks 92 disposed on the four-corner repressing cylinders 90. The four-corner repressing block 92 is provided with a four-corner contouring surface 91 that fits against the corner of the watch case on the side facing the corner of the watch case. The top surface pressure assembly 8 and the four corner pressure assemblies 9 of the watch case facilitate the smoothing of the adhesive film on the watch case from the top surface to the four corners of the watch case, and then from the top of the four corners to the bottom, ensuring good adhesion of the film on the watch case surface, especially the film at the four corners.

[0061] To ensure proper film application, a film under-application camera and a film guide camera are also included. The film under-application camera inspects the film on the vacuum film application head. The film guide camera facilitates the guidance of the vacuum film application head and inspects watch cases, improving the film application effect and yield rate.

[0062] During operation, the feeding equipment (using a multi-axis robot or a conventional transfer robot) transfers the watch case to the secondary positioning stage 122. Then, the intermediate three-jaw cylinder 125 transfers the secondary-positioned watch case to the watch case positioning stage 21. The indexing turntable 20 rotates to rotate the watch case to the film application station. The film application component 3 absorbs a piece of film from the film feeder 1 and transfers it to the watch case. The watch case with the film applied rotates to the first rolling station. The rolling roller 41 moves downward under the drive of the rolling lifting cylinder 45. After contacting the watch case, the rolling arm 42 is pushed outward under the pressure of the rolling roller 41, which rolls and applies the film to the first pair of sides of the watch case. After the rolling roller 41 finishes rolling, the rolling jaw cylinder 44 opens, the rolling roller 41 disengages from the film, and the rolling lifting cylinder 45 rises to reset. Then, the contouring side pressure block 4... The first pair of film materials after rolling is re-pressed to improve the adhesion of the film material. The watch case continues to rotate to the first film picking station. The first film picking pre-pressing head 54 descends and presses down on the second pair of film materials. The first film picking rod 55 rotates to lift the bottom film of the first pair of film materials upward, realizing the separation of the bottom film of the first pair of film materials.
