[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0041] In the description of this invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0042] like Figures 1 to 15 As shown, the smart watch film application and assembly equipment of the present invention includes: a film application station 1 for applying film to the watch case, a laser engraving station 2 for laser engraving the film-applied watch case, and an assembly station 3 for assembling parts onto the laser-engraved watch case.

[0043] At the film application station 1: the watch case is transported to the film application turntable 12, which drives the watch case to rotate. Under the action of the guide camera 18, the film application assembly sequentially applies protective film one to the watch case and presses it, applies protective film two to the watch case and presses it, applies protective film three to the watch case and presses it, and then the re-inspection camera 19 re-inspects the watch case.

[0044] The watch case is fed through a feeding mechanism 11, which includes a feeding module 111 and feeding grippers 112. The feeding module 111 drives the feeding grippers 112 to perform two-dimensional motion, and the feeding grippers 112 clamp the product. There are two feeding grippers 112. Specifically, the feeding module 111 includes a linear module and a stroke cylinder fixedly installed on the moving part of the linear module. The moving part of the stroke cylinder is fixedly connected to the feeding grippers 112. In actual use, the product, i.e., the watch case, is fed through a feeding tray. Then, the linear module drives the stroke cylinder to move closer to the feeding tray. Then, the stroke cylinder drives the feeding grippers 112 to move downward, thereby clamping the watch case in the feeding tray.

[0045] On the film application turntable 12, the rotating mechanism 16 drives the watch case to rotate circumferentially to the required angle; the rotating mechanism 16 includes a rotating fixture 161, a rotating motor 162 that drives the rotating fixture 161 to rotate, and a drive cylinder 163 that drives the rotating motor 162 to move. The rotating fixture 161 is mounted on the film application turntable 12 through bearings, and the watch case is placed on the rotating fixture 161.

[0046] The loading gripper 112 places the watch case onto the rotating fixture 161, and then the film-applying turntable 12 can rotate actively for subsequent operations. When it is necessary to drive the rotating fixture 161 to rotate, the drive cylinder 163 drives the rotary motor 162 to move upward, so that the rotating part of the rotary motor 162 contacts the end of the rotating fixture 161, thereby causing the rotary motor 162 to drive the rotating fixture 161 to rotate. After the rotation is completed, the drive cylinder 163 drives the rotary motor 162 to disengage from the rotating fixture 161.

[0047] The film-applying turntable 12 is equipped with a fixture fixing mechanism 17, which uses a fixture fixing cylinder to move the fixture pressure block downwards to fix the fixture.

[0048] The first film application component 13 applies the first protective film to the watch case and presses it down; the second film application component 14 applies the second protective film to the watch case and presses it down; the third film application component 15 applies the third protective film to the watch case and presses it down. It should be noted in detail here that the protective film is divided into side film one, side film two, and top film, and needs to be applied in three stages.

[0049] Film application components 13, 14, and 15 have the same structure; however, only film application component 14 is described as an example in this application. Film application component 14 includes a film suction module 141, an X-axis moving module 142 that moves the film suction module 141 along the X-axis, a Y-axis moving module 143 that moves the film suction module 141 along the Y-axis, a Z-axis moving module 144 that moves the film suction module 141 along the Z-axis, a rotating module 145 that rotates the film suction module 141, and a pressing module 146 that presses the adhesive block.

[0050] It should be noted here that the film supply mechanism is a common film supply mechanism, which adopts an existing mature design, and will not be described in detail in this application.

[0051] The X-axis moving module 142, Y-axis moving module 143, and Z-axis moving module 144 are all existing mature units that can drive the film suction module 141 to move, and will not be described in detail here. The film suction module 141 includes a negative pressure plate 1411, on which a vacuum generator is connected. A coating head 1412 is fixedly installed on the negative pressure plate 1411. The coating head 1412 can increase the contact area and prevent it from falling off during movement due to insufficient contact surface. The rotating module 145 includes a rotating motor 1451, a corner device 1452 connected to the rotating motor 1451, and a connecting plate 1453 installed on the corner device 1452. The negative pressure plate 1411 is installed on the connecting plate 1453. The adhesive pressing module 146 includes an adhesive pressing block 1461 for pressing adhesive and an adhesive pressing cylinder 1462 for moving the adhesive pressing block 1461.

[0052] It is necessary to explain in detail here that the guide camera 18 has two functions. First, when the loading jaw 112 places the watch case into the rotating fixture 161, the guide camera 18 takes a picture to obtain the initial angle of the watch case. Then, the computer determines the required rotation angle of the watch case. The rotating camera is a servo camera, which can perform precise angle control. Thus, the rotating motor 162 can drive the watch case to make precise angle adjustments. After the angle adjustment is completed, the guide camera 18 takes a second picture to determine whether the watch case has been adjusted to the correct position.

[0053] The conveying assembly transports the film-coated watch case to the first variable-pitch flow line 22, which changes pitch to adapt to the production cycle of the laser engraving station 2. The conveying assembly includes a lifting cylinder, a gripper cylinder mounted on the moving part of the lifting cylinder, and a conveying cylinder that drives the lifting cylinder to move. The conveying cylinder drives the lifting cylinder to move linearly, while the lifting cylinder drives the gripper cylinder to move up and down, thereby gripping the product.

[0054] At the laser engraving station 2: the robotic arm 21 picks up the watch case from the flow line and moves it to the laser engraving assembly to perform laser engraving on the surface of the watch case; the laser engraving assembly is existing equipment, so it will not be described in detail here. It should be noted that the robotic arm 21 is a six-axis robotic arm 21, which is equipped with a material picking gripper. The material picking gripper is coated with rubber to prevent damage. During laser engraving, the robotic arm 21 can drive the watch case to move in all directions to perform laser engraving on the front, back and sides of the watch case.

[0055] The robotic arm 21 places the laser-engraved watch case onto the second variable-pitch flow line 23, which changes pitch to adapt to the production rhythm of the assembly station 3. The variable-pitch flow line includes a support 221, multiple synchronous belts 222 distributed vertically on the support 221, a control motor 223 that drives the synchronous belts 222 to rotate, and a carrier platform 224 that moves with the synchronous belts 222 as they rotate.

[0056] The control motor 223 is a servo motor, which can control the speed of multiple control motors 223, so that the speed of the synchronous belt 222 is different, thereby controlling the movement of the vehicle platform 224, so that multiple vehicle platforms 224 are spaced apart or close to each other.

[0057] A transfer positioning mechanism 24 is provided between the laser engraving station 2 and the assembly station 3. The transfer positioning mechanism 24 includes: a rotary cylinder 241, an upper and lower sliding stage cylinder 242 fixedly installed on the rotating part of the rotary cylinder 241, and a clamping claw 243 installed on the upper and lower sliding stage cylinder 242. The rotary cylinder 241 drives the upper and lower sliding stage cylinder 242 to rotate, and the upper and lower sliding stage cylinder 242 drives the clamping claw 243 to move up and down to clamp the three watch cases on the second variable pitch flow line 23. A positioning fixture is provided on one side of the rotary cylinder 241, and the watch cases are placed in the positioning fixture for easy clamping.

[0058] By setting up a transfer and positioning mechanism 24, the accuracy of the watch case transfer between the two workstations is ensured. As the synchronous belt 222 drives the carrier table 224 to move, the watch case will shake. Setting up a transfer and positioning mechanism 24 can ensure the accuracy of subsequent processing.

[0059] At assembly station 3: the four-axis module 31 places the watch case on the assembly turntable 32; the button one assembly module 3433 picks up button one and places it on the button one secondary positioning plate; after secondary positioning, the button one assembly module 3433 assembles button one onto the watch case; the button two assembly module picks up button two and places it on the button two secondary positioning plate; after secondary positioning, the button two assembly module assembles button two onto the watch case; the snap ring pick-up six-axis module 35 picks up the snap ring and places it on the snap ring assembly assembly 36; finally, the unloading module removes the watch case.

[0060] Button 1 uses a material tray for feeding, and the material tray is lifted and lowered by the material hopper lifting mechanism; the secondary positioning mechanism includes a shifting cylinder 301; and an assembly fixture 302 fixedly installed on the sliding rod of the shifting cylinder 301. There are two shifting cylinders 301. The shifting cylinders 301 drive the assembly fixture 302 to move. The secondary positioning mechanism has two stations, one is the feeding station and the other is the positioning station.

[0061] Both the button assembly module 3433 and the button assembly module 2 are six-axis robotic arms.

[0062] The snap ring assembly 36 includes a case fixing mechanism 361 for pressing and fixing the watch case, a case fixing mechanism 362 for clamping and fixing the watch case from the side, a button fixing mechanism 363 for fixing the buttons, and a snap ring mounting mechanism 364. The first watch case fixing mechanism 361 uses a watch case fixing cylinder 3611 to drive the pressure head 3612 downward to press and fix the watch case; the second watch case fixing mechanism 362 uses a watch case clamping cylinder 3621 to drive the clamping member 3622 closer to clamp and fix the watch case; the third button fixing mechanism 363 uses a button pressing cylinder 3631 to drive the pressing member 3632 closer to the first and second buttons on the watch case to fix them; the fourth snap ring mounting mechanism 364 includes a snap ring mounting cylinder 3641 and a negative pressure adsorption rod 3642 fixedly mounted on the snap ring mounting cylinder 3641. The snap ring mounting cylinder 3641 drives the negative pressure adsorption rod 3642 to move. The negative pressure adsorption rod 3642 is connected to a negative pressure source and adsorbs the snap ring through the negative pressure for assembly; the sixth snap ring pick-up axis 35 picks up the snap ring and places it on the negative pressure adsorption rod 3642.

[0063] The case-fixing cylinder 3611 drives the pressure head 3612 downward until it contacts the case, pressing and fixing it in place. Then, the clamping cylinder drives the clamping member 3622 to approach, clamping and fixing the case from the side. This provides comprehensive fixation from two directions, preventing the case from shaking. The button-pressing cylinder 3631 drives the clamping member 3632 to approach the first and second buttons on the case, fixing them in place and preventing movement. It also maintains pressure on the buttons for a more stable installation. Finally, the negative pressure suction rod 3642 adsorbs the retaining spring. The retaining spring mounting cylinder 3641 drives the negative pressure suction rod 3642 to move from top to bottom, with the retaining spring's locking slot at the bottom, allowing it to snap onto the case.

[0064] The material feeding module is a common design, so I won't go into too much detail here.

[0065] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
