A middle limit glue 1710 is provided on the top of the lower guide post 178, and the middle limit glue 1710 is used to prevent the lower guide post 178 from colliding with the upper stopper 153.

[0054] In this embodiment, a middle pressure spring 155 is installed on the upper guide column 154. When the electric screwdriver 161 moves to the lowest position, the second slider 152 no longer moves downward, and the first slider 151 will continue to move downward under the drive of the Z-axis motor 12, thereby compressing the middle pressure spring 155 by about 2-3 mm through the upper stopper 153. The compression distance here is different according to the length of the screw to be screwed in. The spring force generated by the compressed middle pressure spring 155 pushes the electric screwdriver 161 to continue to move downward to complete the screwing operation. Because the specifications of the screws are different, the required tightening force is different. If a belt drive is used to drive the electric screwdriver 161 to complete the screwing operation, it is very likely that after the screw is screwed in place, the electric screwdriver will continue to move downward, causing damage to the screwdriver, workpiece or screw. Using spring force to complete the screwing operation of the electric screwdriver 161 is conducive to the control of the tightening force and plays a stroke buffering role. An upper limit glue 1513 is installed on the top of the upper guide column 154 , and the upper limit glue 1513 is used to prevent the upper guide column 154 from colliding with the first sensing slot mounting plate 1510 .

[0055] An upper rod 181 is also provided at the upper end of the Z axis rail plate 11, and an upper tension spring 182 connects the upper rod 181 and the upper guide column fixing block 164. The upper tension spring 182 is in a stretched state, and when the electric screwdriver 161 is rising, the upper tension spring 182 can pull the screwdriver fixing plate 163, making the Z axis motor 12 more labor-saving, thereby increasing the life of the Z axis motor 12.

Through the form of tooth matching, the Y-axis slider 214 is clamped on the Y-axis synchronous belt 2133 and can be slidably installed on the Y-axis rail 212. As the Y-axis motor 215 drives the Y-axis synchronous belt 2133 to run along the Y-axis, the rotary motion of the motor can be converted into the linear motion of the Y-axis slider 214 along the Y-axis ( Fig.11 The double-headed arrow on the Y-axis moving mechanism is the Y-axis direction).

[0074] In order to adjust the tightness of the Y-axis synchronous belt 2133, a Y-axis pulley adjustment block 2135 is provided on the Y-axis pulley mounting shaft 2134, a long mounting hole is opened on the Y-axis pulley adjustment block 2135, a screw fixing hole is provided on the Y-axis rail mounting plate 211, and the Y-axis pulley adjustment block 2135 is connected to the Y-axis rail mounting plate 211 through screws. When the tightness of the Y-axis synchronous belt 2133 needs to be adjusted, the screw is loosened, the Y-axis pulley adjustment block 2135 is pushed, and after adjusting the tightness of the Y-axis synchronous belt 2133, the fixing screw is tightened.

[0075] In order to sense the extreme motion position of the Y-axis slider 214 on the Y-axis rail 212, a Y-axis sensing slot 216 is provided at one end of the Y-axis rail mounting plate 211. The Y-axis sensing slot 216 is a slot formed by two separate vertical pieces. A Y-axis sensing block 217 is provided on the Y-axis slider 214. The size of the Y-axis sensing slot 216 is adapted to the size of the Y-axis sensing block 217. When the Y-axis slider 214 slides to the extreme position at the right end of the Y-axis rail 212 in the figure, the Y-axis sensing block 217 will be inserted into the Y-axis sensing slot 216, so that the motor can be controlled to stop running or reverse running through components such as sensors.

The secondary X-axis slider 224 is provided with the same teeth as those on the secondary X-axis synchronous belt 2233. Through the form of tooth matching, the secondary X-axis slider 224 is clamped on the secondary X-axis synchronous belt 2233 and can be slidably mounted on the secondary X-axis axis rail 222. As the secondary X-axis motor 225 drives the secondary X-axis synchronous belt 2233 to operate along the secondary X-axis, the rotary motion of the motor can be converted into the linear motion of the secondary X-axis slider 224 along the secondary X-axis ( Fig.11 The double-headed arrow on the secondary X-axis moving mechanism indicates the direction of the secondary X-axis).

[0078] Similarly, in order to adjust the tightness of the secondary X-axis synchronous belt 2233, a secondary X-axis pulley adjustment block (not shown in the figure) is provided on the secondary X-axis pulley mounting shaft 2234, a screw fixing hole is provided on the secondary X-axis axis rail mounting plate 221, and a long mounting hole is provided on the secondary X-axis pulley adjustment block, and the secondary X-axis pulley adjustment block is connected to the secondary X-axis axis rail mounting plate 221 through a screw.

[0079] like Fig.13 , 14 As shown, in order to achieve the sealing protection and dustproof effect of the moving mechanism, a dustproof frame 32 is fixedly installed on the Y-axis slider 214. The dustproof frame 32 is open at the top, and the cross section is in a maze shape, with multiple grooves on the left and right sides. An upper cover plate 33 is provided at the upper opening of the dustproof frame, and the left and right sides of the upper cover plate 33 are bent and inserted into the grooves with the left and right sides of the dustproof frame 32 facing upward.

A right cover plate 35 is provided on the right side of the dustproof frame 32, and one side of the right cover plate 35 is bent, and the bent side is inserted into the groove with the right side of the dustproof frame 32 facing downward. The dustproof frame 32, the upper cover plate 33, the left cover plate 34 and the right cover plate 35 can be used to shield the Y-axis moving mechanism and play a role in sealing protection. At the same time, the left cover plate 34, the right cover plate 35 and the workbench bottom plate 31 form a box body to form a closed workbench. An upper plate 36 is provided above the dustproof frame 32 , and the upper plate 36 is used to support the secondary X-axis moving mechanism.

[0080] Similarly, a dustproof frame is also fixed on the secondary X-axis slider 224, and an upper cover plate is arranged on the upper part of the dustproof frame, and a left cover plate and a right cover plate are arranged on the left and right sides. Different from the dustproof frame arranged on the Y-axis slider, the left cover plate and the right cover plate form a closed space with the secondary X-axis line rail mounting plate 221 to seal and protect the secondary X-axis moving mechanism.

[0081] In order to improve the structural strength of the workbench, a plurality of column support plates 37 are arranged on the workbench bottom plate 31 . The column support plates 37 can be used to support the Y-axis line rail mounting plate 211 . At the same time, the secondary X-axis motor 225 is installed on the column support plates 37 .

[0082] like Fig.15 , 16 As shown, the frame includes a column 59, a crossbeam plate 58 and a main X-axis moving mechanism.

[0083] Two columns 59 are installed on the workbench bottom plate 31, and two parallel cross beams are installed on the top of the columns 59, namely the main cross beam 58 and the auxiliary cross beam 517.

[0084] The main X-axis moving mechanism is installed on the main crossbeam plate 58, including a main X-axis synchronous belt assembly, a main X-axis axis rail 57, a mounting plate assembly and a main X-axis motor 512. The main X-axis synchronous belt assembly includes a main X-axis main pulley 513, a main X-axis secondary pulley 53, a main X-axis synchronous belt 514 and a main X-axis pulley mounting shaft 52. The main X-axis motor 512 is installed at one end of the main crossbeam plate 58, and the main X-axis pulley mounting shaft 52 is installed at the other end of the main crossbeam plate 58. The main X-axis main pulley 513 is installed on the output shaft of the main X-axis motor 512, the main X-axis secondary pulley 53 is sleeved on the main X-axis pulley mounting shaft 52, and the main X-axis synchronous belt 514 passes around the main X-axis main pulley 513 and the main X-axis secondary pulley 53 to form a closed loop. Driven by the main X-axis motor 512, the main X-axis synchronous belt 514 runs along the main X-axis direction. Fig.15 As shown, the direction indicated by the double-headed arrow in the figure is the main X-axis direction.

[0085] In order to adjust the tightness of the main X-axis synchronous belt 514, a main X-axis pulley adjustment block 51 is provided on the main X-axis pulley mounting shaft 52, and rectangular mounting holes are provided at both ends of the main X-axis pulley adjustment block 51. A screw fixing hole is provided on the main crossbeam plate 58, and the main X-axis pulley adjustment block 51 is connected to the main crossbeam plate 58 through a screw. When the tightness of the main X-axis synchronous belt 54 needs to be adjusted, the screw is loosened, the main X-axis pulley adjustment block 51 is pushed, and after adjusting the belt tightness, the fixing screw is tightened.

[0086] The main X-axis axis rail 57 is installed on the main crossbeam plate 58 below the main X-axis synchronous belt assembly, and the mounting plate assembly includes a screw-tightening side mounting plate 54, a main X-axis synchronous belt clamping block 55, and a main X-axis slider 56. The main X-axis synchronous belt clamping block 55 and the main X-axis slider 56 are fixedly connected to the screw-tightening side mounting plate 54. In this embodiment, the main X-axis synchronous belt 514 is a toothed synchronous belt, and a plurality of spaced teeth are provided on the synchronous belt. The main X-axis synchronous belt clamping block 55 is provided with teeth corresponding to the main X-axis synchronous belt 514, and the main X-axis synchronous belt clamping block 55 is clamped with the main X-axis synchronous belt 514 through the teeth. The main X-axis slider 56 can be slidably installed on the main X-axis axis rail 57. When the main X-axis motor 512 drives the main X-axis synchronous belt 514 to run along the main X-axis, the screw-tightening side mounting plate 54 can move linearly along the main X-axis direction with the movement of the main X-axis synchronous belt 514. The screw-tightening side mounting plate 54 is used to mount the screw tightening mechanism 10 . When the screw tightening mechanism 10 is mounted on the screw-tightening side mounting plate 54 , the motion control of the screw tightening mechanism 10 in the main X-axis direction can be realized.

[0087] like Fig.15 As shown, a screen box 515 is also installed on the right column 59, and a control system 516 is installed in the screen box 515. The control system 516 is electrically connected to the main X-axis motor 512 for controlling the rotation of the main X-axis motor.

[0088] like Fig.16 As shown, an anti-skid pad side mounting plate 518 is installed on the secondary cross beam plate 517, and the anti-skid pad side mounting plate 518 is used to install the anti-skid pad mechanism 60. Since the anti-skid pad mechanism 60 only needs to move in the longitudinal axis direction, a moving mechanism in the main X-axis direction is not set.

[0089] The working principle of the present invention is as follows: the workpiece is placed on the multi-purpose workbench mechanism 20, and the multi-purpose workbench mechanism 20 controls the position of the Y-axis and the secondary X-axis of the workpiece, thereby achieving precise positioning. The screw tightening mechanism 10 first makes a linear motion in the main X-axis direction on the frame. When it reaches the top of the screw arrangement machine 40, the Z-axis motor 12 drives the Z-axis synchronous belt 133 to operate, thereby driving the first slider 151 to move downward, and the electric screwdriver 161 also moves downward under the action of gravity, and sucks the screws on the screw arrangement machine 40 through the suction nozzle 171. After sucking the screw, the screw tightening mechanism 10 reaches the top of the screw hole of the workpiece 80 along the main X-axis direction, and the Z-axis motor 12 continues to drive the first slider 151 to move, compressing the middle compression spring to the required length of screwing in the screw, and the electric screwdriver starts, and through the pressure of the middle compression spring 155, the screwing operation is completed along the Z-axis downward. After the screw is screwed into place, the Z-axis motor 12 drives the electric screwdriver 161 to move upward along the Z-axis. After the workpiece 80 is transferred to another screw hole through the multi-purpose workbench mechanism 20, the screw tightening mechanism 10 completes the next screw suction and screw tightening operation.

[0090] After all the screws on the workpiece are tightened, the multi-purpose workbench mechanism 20 positions the workpiece in the Y-axis and sub-X-axis directions through the Y-axis moving mechanism and the sub-X-axis moving mechanism, and moves the workpiece to the position where the anti-slip pad is required.

[0091] The inlet side pulling clamp 724 and the outlet side pulling clamp 734 simultaneously clamp the anti-skid pad 74, and at this time, the inlet side clamping clamp 725 and the outlet side clamping clamp 735 are in an open state. The inlet side pulling cylinder 721 and the outlet side pulling cylinder 731 respectively push the inlet side pulling clamp 724 and the outlet side pulling clamp 734 to move along the forward direction of the anti-skid pad 74, thereby achieving a diameter distance of a circular pad pulled out from the material tray 711. At the same time, the inlet side pulling cylinder 721 drives the adhesive paper pulling clamp 728 to move a diameter distance of a circular pad, thereby tearing off the adhesive paper 76 at the bottom of the anti-skid pad 74. Then, the inlet side clamping clamp 725 and the outlet side clamping clamp 735 clamp the anti-skid pad 74, so that the anti-skid pad 74 is in a tensioned state.

[0092] At this time, the pad motor 61 drives the pad main pulley 62 to operate, thereby driving the pad synchronous belt 63 to operate, and the pad cylinder 615 fixed on the pad synchronous belt 63 will reciprocate up and down on the pad linear track 67 with the operation of the pad synchronous belt 63. The initial state of the pad cylinder 615 is that the cylinder axis is in a contracted state, and the pad cylinder 615 is at the upper end of the pad linear track 67. After that, the pad motor 61 drives the pad cylinder 615 to move downward along the pad linear track 67 to the lowermost end of the pad linear track 67, and the cylinder axis of the pad cylinder 615 extends, and the glue punch 617 hits the anti-skid pad belt located below the anti-skid pad sticking mechanism. The anti-skid pad belt is provided with a plurality of spaced circular anti-skid pads, and after the glue punch 617 hits the anti-skid pad belt, the circular anti-skid pad can be separated from the pad belt and stuck on the workpiece.

[0093] After one anti-skid pad is attached, the inlet side pull clamp 724 and the outlet side pull clamp 734 release the anti-skid pad belt 74, and as the inlet side pull cylinder 721 and the outlet side pull cylinder 731 shafts shrink back to the initial position, the inlet side pull clamp 724 and the outlet side pull clamp 734 also return to the initial position. The above operation is repeated to allow the anti-skid pad feeding system to continuously feed materials, and cooperate with the anti-skid pad attaching mechanism 60 and the multi-purpose workbench mechanism 20 to attach the remaining anti-skid pads to the workpiece.

[0094] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
