[0024] like Figure 2-3 As shown, the pallet device 200 includes a pallet drive assembly and a turntable adjustment mechanism. The turntable adjustment mechanism includes a double-layer pallet assembly, a pallet longitudinal adjustment assembly, and a locking assembly. The pallet drive assembly is used to drive the double-layer pallet assembly to rotate.

[0025] The double-layer pallet assembly includes an upper pallet 202 and a lower pallet 206 disposed above the mechanism mounting plate 100. The upper pallet 202 and the lower pallet 206 are arranged at an interval between the upper and lower layers. The outer edge of the upper pallet 202 is provided with a plurality of first opening slots 207, and the outer edge of the lower pallet 206 is provided with a plurality of second opening slots 209. The screw feeding device 101 is used to realize the automatic conveying of the screw, and the screw pushing device 102 pushes the screw into the upper pallet 202 and the lower pallet 206.

[0026] The longitudinal adjustment component of the tray is used to adjust the longitudinal spacing between the lower tray 206 and the upper tray 202 to accommodate screws of different lengths. The upper part of the screw is embedded in the first opening groove 207, and the lower part of the screw is embedded in the second opening groove 209. At the same time, the bottom of the screw is supported by the base plate 211, so that when the double-layer tray assembly rotates, the screw can be stably supported and kept in a vertical state.

[0027] The pallet longitudinal adjustment assembly includes a support plate 217, a base 211, and a movable connector 218. The movable connector 218 is provided with external threads, and the mechanism mounting plate 100 is provided with a movable groove for the movable connector 218 to move up and down. The support plate 217 is located below the mechanism mounting plate 100 and is fastened to the bottom end of the movable connector 218. The base 211 is located below the lower pallet 206 and is fastened to the top end of the movable connector 218. Furthermore, the mechanism mounting plate 100 is equipped with a plurality of linear bearing seats 213. A guide rod 215 is provided between the support plate 217 and the base 211. The guide rod 215 slides with the linear bearing seats 213, thereby improving the smoothness of adjusting the longitudinal position of the lower pallet 206.

[0028] The mechanism mounting plate 100 is equipped with an upper baffle assembly, which includes an upper baffle 203 and a plurality of support rods 205. The support rods 205 are fastened to the mechanism mounting plate 100. The upper baffle 203 is arc-shaped and is stably mounted on the edge of the upper tray 202 through the support rods 205.

[0029] The chassis 211 is equipped with a lower baffle assembly, which includes a lower baffle 204 and multiple connecting brackets. One end of the connecting bracket is fastened to the chassis 211. The lower baffle 204 is arc-shaped and is securely mounted on the edge of the lower tray 206 through the connecting bracket.

[0030] The upper baffle 203 and the lower baffle 204 are provided to prevent the screw from disengaging from the first opening slot 207 and the second opening slot 209. Both the upper baffle 203 and the lower baffle 204 are provided with a third opening slot 208, and the two third opening slots 208 are aligned with each other. The third opening slot 208 is provided to cooperate with the flat pad clamping device 104. The flat pad clamping device 104 clamps the screw and allows it to disengage from the upper tray 202 and the lower tray 206 from the third opening slot 208. After the flat pad clamping process is completed, the screw is pushed back into the upper tray 202 and the lower tray 206.

[0031] The locking assembly is used to restrict the position of the lower tray 206. The locking assembly includes a first locking nut 210 and a second locking nut 212. The first locking nut 210 is located above the mechanism mounting plate 100, and the second locking nut 212 is located below the mechanism mounting plate 100. The first locking nut 210 and the second locking nut 212 are respectively threadedly connected to the movable connector 218 and restrict the longitudinal position of the movable connector 218, so that the longitudinal position of the lower tray 206 is fixed.

[0032] The tray drive assembly is used to drive the upper tray 202 and the lower tray 206 to rotate synchronously. The interior of the movable connector 218 is hollow. The tray drive assembly includes a rotary drive 301, a drive gear 302, a transmission gear 303 and a rotating shaft 304. The rotating shaft 304 is provided with multiple key bars 216.

[0033] A first connector 201 is provided near the upper tray 202 of the rotating shaft 304. The first connector 201 is fastened to the upper tray 202 by locking bolts, so that the position of the upper tray 202 is fixed, and the upper tray 202 is driven to rotate together when the rotating shaft 304 rotates.

[0034] The chassis 211 is equipped with a second connector 214 for connecting the lower tray 206. The rotating shaft 304, after having a rotating component 305 sleeved on its outer side, passes sequentially through the support plate 217, the movable connector 218, the chassis 211, and the second connector 214. The outer wall of the rotating component 305 is smooth, and the inner wall of the rotating component 305 is provided with a keyway that mates with the key bar 216. The top of the rotating component 305 is equipped with a connecting ring for rotating the lower tray 206. When adjusting the longitudinal spacing between the lower tray 206 and the upper tray 202, the lower tray 206 rotates accordingly. The movable connector 218 moves together, and both the upper tray 202 and the lower tray 206 are provided with keyways for cooperating with the key bar 216. The transmission gear 303 is provided with a bolt groove for fastening to the rotating shaft 304 and a keyway for cooperating with the key bar 216. Therefore, during the rotation of the rotating shaft 304, the support plate 217, the movable connector 218, the second connector 214, and the chassis 211 are all fixed, while the transmission gear 303, the rotating part 305, the upper tray 202, and the lower tray 206 rotate with the rotation of the rotating shaft 304.

[0035] The transmission gear 303 is slidably mounted on the rotating shaft 304. The rotation drive 301 is a conventional servo motor or other drive component. The rotation drive 301 is responsible for providing rotational power to drive the drive gear 302 to rotate. The drive gear 302 and the transmission gear 303 mesh with each other. The rotation drive 301 drives the drive gear 302 to rotate, which in turn drives the transmission gear 303 to rotate. The transmission gear 303 drives the rotating shaft 304 to rotate, which in turn drives the upper tray 202 and the lower tray 206 to rotate together. The upper tray 202 and the lower tray 206 drive the screw to move from the screw pushing device 102, through the screw detection device, the flat pad feeding device 103, the flat pad detection device, the flat pad pressing device 104, the screw sleeve pressing device 105, the screw sleeve pressing device 106, the nut tightening device 107, and the finished product detection device, and finally to the finished product distribution device 110.

[0036] The steps for adjusting the longitudinal spacing between the lower tray 206 and the upper tray 202 are as follows:

[0037] First, loosen the first locking nut 210 and the second locking nut 212 so that the movable connecting piece 218 can move up and down.

[0038] The second step is to move the movable connector 218 to adjust the longitudinal spacing between the lower tray 206 and the upper tray 202 from the target until the longitudinal spacing between the lower tray 206 and the upper tray 202 is adjusted to a suitable length for the screw, so that the upper part of the screw is embedded in the first opening groove 207 and the lower part of the screw is embedded in the second opening groove 209, while the bottom of the screw is supported by the base plate 211.

[0039] The third step is to tighten the first locking nut 210 and the second locking nut 212, so that the movable connector 218 can no longer move, thereby achieving the purpose of fixing the position of the lower tray 206.

[0040] Compared with traditional technology: The longitudinal adjustment component of the pallet is used to adjust the longitudinal spacing between the lower pallet 206 and the upper pallet 202 to accommodate screws of different lengths. The upper part of the screw is embedded in the first opening slot 207, and the lower part of the screw is embedded in the second opening slot 209. At the same time, the bottom of the screw is supported by the base plate 211, so that when the double pallet assembly rotates, the screw can be stably supported and kept in a vertical state, which facilitates the subsequent processing and inspection of the screw.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
