[0037] The following reference Figures 1 to 7 This application describes a vibration module protective cover assembly system according to some embodiments.

[0038] This application provides a vibration module protective cover assembly system for fitting a protective cover into the case of a smartwatch, so that the protective cover covers the vibration module inside the case, thereby protecting the vibration module of the smartwatch. Figure 1 and Figure 2 As shown, the vibration module protective cover assembly system includes a first conveying device 1, a feeding device 4, and a robotic arm 5. A fixture 11 containing a smartwatch case can be placed manually or mechanically onto the first conveying device 1. The first conveying device 1 forms an assembly station, through which the fixture 11 and the watch case within it are conveyed to the assembly station. The feeding device 4 is used to place the protective cover. The robotic arm 5 picks up the protective cover from the feeding device 4, then transfers it to the assembly station and inserts it into a predetermined position within the watch case, thus covering the vibration module and completing the automated assembly of the vibration module protective cover, improving production efficiency.

[0039] In one embodiment of this application, preferably, the first conveying device 1 forms a jig loading station upstream of the assembly station, and the first conveying device 1 forms an inspection station and a jig unloading station downstream of the assembly station; the jig loading station, assembly station, inspection station and jig unloading station are distributed at intervals along the conveying direction of the first conveying device 1. When the jig 11 containing the watch case is placed on the first conveying device 1, the first conveying device 1 can convey the jig 11 and the watch case inside the jig 11 to the jig loading station, assembly station, inspection station and jig unloading station in sequence.

[0040] When the fixture 11 containing the watch case is conveyed to the fixture loading station, the fixture 11 will remain at that station. A first CCD component 12 is installed at the fixture loading station. The first CCD component 12 can take pictures of the fixture 11 to detect whether its placement orientation on the first conveying device 1 is correct. If the first CCD component 12 detects an incorrect placement orientation of the fixture 11, the operator will remove the fixture 11, adjust its placement orientation, and then reposition the fixture 11 back into the fixture loading station of the first conveying device 1. The first CCD component 12 checks the placement direction of the fixture 11 again. If the placement direction is correct, the fixture 11 can be transported to the downstream assembly station through the first conveying device 1. Thus, the first CCD component 12 realizes the foolproof positioning detection of the fixture 11, ensuring that the fixture 11 and the watch case inside the fixture 11 enter the assembly station in the correct placement direction, thereby ensuring precise cooperation with the robot arm 5, so that the robot arm 5 can accurately install the protective cover in the predetermined position of the watch case, and complete the automated assembly of the protective cover.

[0041] In this embodiment, preferably, a first barcode scanning device is also provided at the jig loading station. The jig 11 is provided with a specific identification code. The first barcode scanning device can scan and identify the identification code on the jig 11 to bind the jig 11.

[0042] In this embodiment, preferably, as follows: Figure 1 and Figure 6 As shown, a fixture handling mechanism 16 is also provided at the fixture loading station. The fixture handling mechanism 16 includes a first stop device 161, a lifting device 162, a limiting device 163, and a wire straightening device 164.

[0043] The first stop device 161 is used to stop the fixture 11, so that the fixture 11 stops at the fixture loading station. Preferably, the first stop device 161 includes a stop cylinder, which is disposed below the first conveying device 1. When the fixture 11 is conveyed to the fixture loading station, the movable end of the stop cylinder can extend above the first conveying device 1 to stop in front of the fixture 11 in the running direction. So when the fixture 11 reaches the fixture loading station, the front end of the fixture 11 will abut against the movable end of the stop cylinder, so that the fixture 11 cannot continue to move forward and stops at the fixture loading station.

[0044] The lifting device 162 is used to lift the fixture 11 away from the first conveying device 1 at a predetermined height and to position the fixture 11. Preferably, the lifting device 162 includes a lifting cylinder and a support plate, the support plate being the movable end of the lifting device 162, and the lifting cylinder driving the support plate to rise and fall. The support plate includes a first support portion and a second support portion, which are disposed opposite to each other on both sides of the width direction of the first conveying device 1, and the first and second support portions are located below the fixture 11. When the lifting cylinder drives the support plate to rise, the first and second support portions will support the fixture 11 and lift the fixture 11 away from the first conveying device 1 at a predetermined height, so that the fixture 11 is stably stopped at the fixture loading station.

[0045] Preferably, the first support part and the second support part are respectively provided with positioning pins, and the fixture 11 is provided with positioning holes at the positions opposite to the positioning pins. When the first support part and the second support part support the fixture 11, the positioning pins on the first support part and the second support part can pass through the corresponding positioning holes to the fixture 11, thereby positioning the fixture 11 and preventing the fixture 11 from shaking.

[0046] The limiting device 163 is used to press the fixture 11 onto the support plate of the lifting device 162. Preferably, the limiting device 163 is located on one side of the width direction of the first conveying device 1. The limiting device 163 includes a limiting cylinder and a limiting plate connected to each other. The limiting plate is the movable end of the limiting device 163. The limiting cylinder can drive the limiting plate to extend from one side of the first conveying device 1 to above the first conveying device 1. The limiting plate is U-shaped and includes a first limiting part and a second limiting part. When the lifting device 162 lifts the fixture 11 away from the first conveying device 1 at a predetermined height, the first limiting part and the second limiting part will press tightly against both sides of the fixture 11, thereby pressing the fixture 11 onto the lifting device 162 to further limit and fix the fixture 11.

[0047] The cable straightening device 164 is used to push down the cable inside the watch case. Preferably, the cable straightening device 164 is located on one side of the width direction of the first conveying device 1. The cable straightening device 164 includes a flat-push cylinder and a pusher connected to each other. The pusher is the movable end of the cable straightening device 164. The flat-push cylinder can drive the pusher to move from the side above the fixture 11 to the other side, and push down the raised cable through the pusher, so that the cable is guided to one side of the watch case, thereby removing the cable from above the vibration module inside the watch case.

[0048] After the fixture 11 completes the foolproof positioning test at the fixture loading station, the movable end of the straightening and wiring device 164, the movable end of the limiting device 163, and the movable end of the first stop device 161 all retract, and the lifting device 162 descends to put the fixture 11 back onto the first conveying device 1, so that the fixture 11 can be conveyed to the downstream assembly station through the first conveying device 1.

[0049] In this embodiment, preferably, the assembly station is also provided with a first stop device 161, a lifting device 162, a limiting device 163, and a wire straightening device 164. When the fixture 11 arrives at the assembly station, the movable end of the first stop device 161 extends to stop the fixture 11 at the assembly station, the movable end of the limiting device 163 extends above the fixture 11, the movable end of the lifting device 162 rises to lift the fixture 11 away from the first conveying device 1 until the movable end of the limiting device 163 presses against the fixture 11 and positions the fixture 11; the movable end of the wire straightening device 164 extends to push the wire inside the casing away from above the vibration module.

[0050] Preferably, a second CCD component 13 is also provided at the assembly station. A spring piece for connecting with the protective cover is provided inside the watch case. Before the protective cover is assembled into the watch case, the spring piece inside the watch case is photographed and inspected by the second CCD component 13 to check the position and size of the spring piece and determine whether the spring piece is qualified. After confirming that the spring piece is qualified, the protective cover can be placed into the watch case by the robot arm 5, so that the protective cover is assembled with the watch case by the spring piece of the watch case.

[0051] After the protective cover is assembled, the movable end of the cable straightening device 164, the movable end of the limiting device 163, and the movable end of the first stop device 161 are retracted, and the lifting device 162 is lowered to put the fixture 11 back onto the first conveying device 1, so that the fixture 11 can be conveyed to the downstream testing station through the first conveying device 1.

[0052] In this embodiment, preferably, the inspection station is also equipped with a first stop device 161, a lifting device 162, a limiting device 163, and a wire straightening device 164 to stably hold the fixture 11 at the inspection station, which will not be described in detail here. Preferably, the inspection station is equipped with a third CCD component 14, which can take pictures of the protective cover assembled into the watch case to detect the relative position and dimensions of the protective cover and the fixture 11, so as to detect the assembly accuracy of the protective cover. After the inspection is completed, the fixture 11 is transported to the fixture unloading station by the first conveying device 1.

[0053] Preferably, a second barcode scanning device is provided at the testing station to perform a second scan and identification of the identification code on the fixture 11, and to bind the fixture 11 by scanning the code.

[0054] Preferably, a first stop device 161 and a lifting device 162 are also provided at the fixture unloading station. The first stop device 161 stops the fixture 11 at the fixture unloading station; the lifting device 162 lifts the fixture 11 away from the first conveying device 1, so that the fixture 11 is stably stopped at the fixture unloading station for subsequent operations.

[0055] In one embodiment of this application, preferably, as shown below, Figure 1 and Figure 2 As shown, the vibration module protective cover assembly system also includes a second conveying device 2 and a third conveying device 3; wherein the second conveying device 2 has the same conveying direction as the first conveying device 1, and the second conveying device 2 is located below the first conveying device 1. Combined with... Figure 7As shown, the second conveying device 2 is used to convey the tray 21 for placing the fixture 11. The second conveying device 2 has a tray loading station at one end near the fixture loading station and a tray unloading station at the other end near the fixture unloading station. The tray 21 containing the fixture 11 can be placed into the second conveying device 2 manually or mechanically. The second conveying device 2 then transports the fixture 11 and the tray 21 within it to the tray loading station. Once the tray 21 reaches the tray loading station, it remains there. The operator can then remove the fixture 11 containing the watch case from the tray 21 and place it on the first conveying device 1 above. This allows the fixture 11 to move the watch case from the fixture loading station to the fixture unloading station on the first conveying device 1, completing the assembly of the protective cover and the assembly qualification inspection.

[0056] During the movement of jig 11 from the jig loading station of the first conveying device 1 to the jig unloading station, the second conveying device 2 continues to transport the tray 21 forward to the tray unloading station, and the tray 21 can stay at the tray unloading station when it arrives. If the third CCD component 14 detects that the assembly of the protective cover and the watch case is qualified, the jig 11 at the jig unloading station will be removed from the first conveying device 1 and put back into the tray 21 located at the tray unloading station of the second conveying device 2. Then, the tray 21 and the jig 11 in the tray 21 will be sent out of the second conveying device 2 by the second conveying device 2.

[0057] The head of the third conveying device 3 faces the jig unloading station of the first conveying device 1. If the third CCD component 14 detects that the assembly of the protective cover and the watch case is not qualified, the jig 11 at the jig unloading station will be removed from the first conveying device 1 and placed on the third conveying device 3 so that the defective product can be sent out for recycling through the third conveying device 3.

[0058] In this embodiment, preferably, a second stop device is provided at the pallet loading station and the pallet unloading station respectively. The movable end of the second stop device can extend to the front of the pallet 21 to prevent the pallet 21 from moving forward and to stop the pallet 21 at the pallet loading station or the pallet unloading station, thereby facilitating the loading and unloading of the fixture 11.

[0059] Preferably, the second conveying device 2 is also equipped with a sensor at the pallet loading station. The sensor can perform foolproof positioning detection on the pallet 21 at the pallet loading station to ensure that the pallet 21 is placed on the second conveying device 2 in the correct orientation. If the sensor detects that the pallet 21 is placed in the wrong orientation, the operator can manually adjust the orientation of the pallet 21 to place it on the second conveying device 2 in the correct orientation, thereby ensuring that the fixture 11 can be accurately transferred from the fixture unloading station to the pallet 21 at the pallet unloading station.

[0060] In this embodiment, preferably, in order to realize the transfer of the jig 11 to the second conveying device 2 or the third conveying device 3, a jig transfer mechanism 15 is also provided at the jig unloading station.

[0061] like Figure 4 As shown, the fixture transfer mechanism 15 includes a first slide 151, a second slide 152, and a pneumatic gripper 153. The first slide 151 is horizontally arranged and mounted above the first conveying device 1. One end of the first slide 151 in the longitudinal direction is located above the fixture unloading station, and the other end of the first slide 151 in the longitudinal direction is located above the pallet unloading station. The second slide 152 is arranged vertically and is slidably connected to the first slide 151. The pneumatic gripper 153 is slidably connected to the second slide 152. The first slide 151 can drive the pneumatic gripper 153 to move between the fixture unloading station and the pallet unloading station, and the second slide 152 can drive the pneumatic gripper 153 to rise and fall.

[0062] When the protective cover and the watch case are assembled successfully, the jig 11 needs to be transferred from the jig unloading station to the tray 21 at the tray unloading station. First, the pneumatic gripper 153 is moved to the jig unloading station by the first slide 151 and the second slide 152, and the jig 11 is picked up by the pneumatic gripper 153. Then, the pneumatic gripper 153 and the jig 11 are moved to the tray unloading station by the first slide 151 and the second slide 152, and the jig 11 is placed into the tray 21 by the pneumatic gripper 153, thus completing the transfer of the jig 11 containing the qualified product.

[0063] When the assembly of the protective cover and the watch case is not satisfactory, the jig 11 needs to be transferred from the jig unloading station to the third conveying device 3. Preferably, as follows: Figure 2 and Figure 3 As shown, the head end of the third conveying device 3 is provided with a material picking mechanism 31 and a material pushing mechanism 32. The material picking mechanism 31 includes a material picking component 311 and a material picking drive device 312. The movable ends of the material picking component 311 and the material picking drive device 312 are connected. The material picking drive device 312 can drive the material picking component 311 to extend to the fixture unloading station of the first conveying device 1 and stop above the first conveying device 1. During the process of transferring the fixture 11 containing defective products from the first conveying device 1 to the third conveying device 3, the pneumatic gripper 153 first picks up the fixture 11 and stops the fixture 11 above the first conveying device 1. The material picking drive device 312 drives the material picking component 311 and even the top of the first conveying device 1 so that the pneumatic gripper 153 places the gripped fixture 11 on the material picking component 311. Then, the material picking drive device 312 drives the material picking component 311 to retract, thereby moving the fixture 11 containing defective products to the top of the third conveying device 3.

[0064] The feeding device includes a feeding component 321 and a feeding drive device 322. One end of the feeding component 321 is connected to the movable end of the feeding drive device 322, and the other end of the feeding component 321 is located on the picking component 311 and has a hook 323. The movable end of the feeding drive device 322 can extend and retract synchronously with the movable end of the picking drive device 312 so that the hook 323 of the feeding component 321 can move with the picking component 311 between the fixture unloading station and the third conveying device 3.

[0065] When the jig 11 is placed on the picking member 311, the jig 11 is located inside the hook 323 of the feeding member 321. After the picking member 311 moves the jig 11 above the third conveying device 3, the feeding drive device 322 can drive the feeding member 321 to continue to retract, so that the jig 11 is pushed off the picking member 311 and falls onto the third conveying device 3 through the hook 323 of the feeding member 321. Then, the jig 11 containing the defective product can be sent out through the third conveying device 3.

[0066] In one embodiment of this application, the feeding device 4 is used to supply the protective cover; preferably, as shown in the following example... Figure 6 As shown, the feeding device 4 includes a frame 45, a material tray 41, a material tray support 46, and an adsorption mechanism 47; the frame 45 has a first station 451 and a second station 452, the first station 451 and the second station 452 are arranged side by side, and a feeding bin 48 is formed below the first station 451 of the frame 45, and a recovery bin 49 is formed below the second station 452 of the frame 45.

[0067] The material tray 41 has multiple receiving cavities, each of which can hold a protective cover; there are multiple material trays 41, and multiple material trays 41 filled with protective covers can be stacked in the loading hopper 48 below the first station 451.

[0068] The material tray bracket 46 is slidably mounted on the frame 45, allowing the material tray bracket 46 to move between the first station 451 and the second station 452; the adsorption mechanism 47 is vertically mounted at the first station 451 of the frame 45, allowing the adsorption mechanism 47 to rise above the first station 451 or descend into the loading hopper 48 below the first station 451.

[0069] In practical use, the tray support 46 is first moved to the second station 452, so that the adsorption mechanism 47 can be lowered into the loading hopper 48 below the first station 451. The adsorption end of the adsorption mechanism 47 picks up the tray 41 located at the top and drives the tray 41 back to the top of the first station 451. Then, the tray support 46 is moved to the first station 451, the adsorption mechanism 47 places the tray 41 on the tray support 46, and the tray support 46 drives the tray 41 to the second station 452. The robot arm 5 can pick up the protective cover in the tray 41 at the second station 452 and transfer the protective cover to the assembly station of the first conveying device 1 for assembly with the case.

[0070] Preferably, the frame 45 is provided with a clamping mechanism 44 at the second station 452. When the tray support 46 moves the tray 41 to the second station 452, the mechanism of the frame 45 can clamp the tray 41 to fix it at the second station 452. The tray support 46 can then move out from under the tray 41 and return to the first station 451 to receive the next tray 41. After all the protective shells in the tray 41 at the second station 452 have been removed, the clamping mechanism 44 releases its grip on the tray 41, and the tray 41 will fall into the recycling bin 49 below the second station 452 for temporary storage and recycling.

[0071] In this embodiment, preferably, as follows: Figure 6 As shown, the bottom of the feeding bin 48 and the recycling bin 49 are respectively provided with a pull-out base plate 481. The material tray 41 is placed on the base plate 481. When it is necessary to place the material tray 41 into the feeding bin 48 or to remove the material tray 41 from the recycling bin 49, the base plate 481 can be pulled out to move the material tray 41 out of the frame 45, so as to facilitate the operator to pick up and put down the material tray 41.

[0072] Preferably, such as Figure 6 As shown, the feeding bin 48 and the recovery bin 49 are respectively equipped with a lifting plate 482 and a lifting drive device.

[0073] A lifting drive device is mounted on the frame 45. The lifting plate 482 is horizontally placed in the corresponding feeding bin 48 or recycling bin 49, and the lifting plate 482 is connected to the movable end of the lifting drive device so that the lifting plate 482 can be driven to move up and down in the corresponding feeding bin 48 or recycling bin 49. Preferably, a through hole is provided at the position opposite to the lifting plate 482 on the bottom plate 481, and the through hole is adapted to the lifting plate 482, so that when the lifting plate 482 moves up and down, the lifting plate 482 can pass through the through hole through the bottom plate 481 to move above or below the bottom plate 481.

[0074] When placing the tray 41 into the loading hopper 48, the lifting drive device first moves the lifting platform 482 to below the base plate 481, then pulls out the base plate 481, allowing the operator to place multiple stacked trays 41 onto it. The base plate 481 is then pushed back into the loading hopper 48, and the trays 41, driven by the base plate 481, enter the loading hopper 48 and move above the lifting platform 482. During the process of the adsorption mechanism 47 picking up the trays 41 from the loading hopper 48, the lifting drive device can drive the lifting platform 482 upwards to raise the trays 41 to a predetermined height, facilitating the adsorption mechanism 47 to pick up the trays 41.

[0075] For the recycling bin 49, the lifting drive device can drive the lifting plate 482 to rise below the clamping mechanism 44 to receive the material tray 41 lowered by the clamping mechanism 44. Then, as the material tray 41 is gradually placed into the recycling bin 49, the lifting drive device also drives the lifting plate 482 to descend to a predetermined height to receive the material tray 41 lowered by the clamping mechanism 44 above, so that the empty material trays 41 are stacked on the lifting plate 482 in sequence. Until the lifting drive device drives the lifting plate 482 to descend below the bottom plate 481, the material tray 41 located above the lifting plate 482 will be placed on the bottom plate 481 of the recycling bin 49. At this time, the recycling bin 49 is in a full state, and the operator can pull out the bottom plate 481 to remove the empty material trays 41.

[0076] In this embodiment, preferably, as follows: Figure 1 and Figure 2 As shown, the feeding device 4 also includes a fourth CCD component 42 and a fifth CCD component 43; the fourth CCD component 42 is movably mounted above the frame 45, so that the fourth CCD component 42 can move to above any receiving cavity of the material tray 41 located at the second station 452, so as to take pictures and position the upper surface of each protective cover at the second station 452 for detection, so that the robot arm 5 can accurately pick up each protective cover.

[0077] The fifth CCD component 43 is mounted on the frame 45. The robotic arm 5 can move the picked-up protective cover above the fifth CCD component 43 so that the fifth CCD component 43 can take pictures and position the lower surface of the protective cover. This allows the robotic arm 5 to move the protective cover into the watch case in an accurate position and assemble it with the watch case.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
