The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] A four-side alignment structure for a cover plate, such as Figure 1 As shown, it includes a base plate 1, a material sensor 11 arranged on the base plate 1, two Y-axis slide rails 2 respectively arranged on both sides of the base plate 1, and two X-axis slide rails 3 slidably connected between the two Y-axis slide rails 2, wherein a first alignment component 4 and a third alignment component 6 are arranged on one of the X-axis slide rails 3, and a second alignment component 5 and a fourth alignment component 7 are arranged on the other X-axis slide rail 3, the third alignment component 6 and the fourth alignment component 7 are fixedly connected to the X-axis slide rail 3, the first alignment component 4 and the second alignment component 5 are slidably connected to the X-axis slide rail 3, and the four-side alignment structure also includes a synchronization component 8 for making the first alignment component 4 and the second alignment component 5 move synchronously, and two driving components 9 that respectively drive the synchronization component 8 and the two X-axis slide rails 3 to move;

[0024] like Figure 2As shown, the first alignment component 4, the second alignment component 5, the third alignment component 6 and the fourth alignment component 7 all include a support base 41, an alignment unit 42 and a support unit 43 arranged on the support base 41, the alignment unit 42 is L-shaped, and the upper side of the support unit 43 is an inclined surface, the support base 41 of the third alignment component 6 and the fourth alignment component 7 is fixedly connected to the X-axis slide rail 3, and the support base 41 of the first alignment component 4 and the second alignment component 5 is slidably connected to the X-axis slide rail 3.

[0025] It can be understood that when the manipulator places the cover plate 10 on the support units 43 of the first alignment component 4, the second alignment component 5, the third alignment component 6 and the fourth alignment component 7, the four corners of the cover plate 10 are respectively located on the support units 43 of the first alignment component 4, the second alignment component 5, the third alignment component 6 and the fourth alignment component 7, and the material sensor 11 will sense the cover plate 10. At this time, the two drive components 9 will operate. Initially, the operator can adjust the operating parameters of the two drive components 9 through the control system according to the model of the cover plate 10, and one of the drive components 9 will be driven. The operation of the component 9 will drive the two X-axis slide rails 3 to move toward each other, that is, one of the two X-axis slide rails 3 moves to the rear side, and the other X-axis slide rail 3 moves to the front side. The two X-axis slide rails 3 move toward each other and drive the support seats 41 thereon to operate toward each other. The support seat 41 drives the support unit 43 and the alignment unit 42 thereon to move, so that the alignment unit 42 aligns the front and rear sides of the cover plate 10. When moving, the side of the support unit 43 close to the center of the cover plate 10 is inclined, and the cover plate 10 is composed of an ink portion 101 and a sensor glass portion 102. The ink portion 101 contacts the support unit 43, and the sensor glass portion 102 does not contact the support unit 43. The support unit 43 has an inclined surface on one side so that the sensor glass portion 102 can be suspended in the air to prevent the sensor glass portion 102 from contacting the support unit 43. When the support unit 43 and the alignment unit 42 align the cover plate 10, the sensor glass portion 102 will not be worn and thus damaged. In addition, the support length of the support unit 43 can be increased, so that the robot can easily place the cover plate 10 on the support unit 43. The operation of another driving component 9 will drive the synchronization component 8 to move towards the direction close to the cover 10, that is, to the left side. The movement of the synchronization component 8 will drive the support base 41 of the first alignment component 4 and the second alignment component 5 to move to the left side, and the support unit 43 and the alignment unit 42 of the support base 41 of the first alignment component 4 and the second alignment component 5 will also move to the left side, while the third alignment component 6 and the fourth alignment component 7 cannot move to the right side, thereby aligning the left and right sides of the cover 10 to achieve high-precision alignment of the four sides of the cover 10.

[0026] like Figure 3As shown, the alignment unit 42 includes two sliding units fixedly connected to the support base 41, and an L-shaped correction piece 424 arranged between the two sliding units. The sliding unit includes a first sliding sleeve 421 fixedly connected to the support base 41, a first slider 422 slidingly connected in the first sliding sleeve 421, and a first spring 423 connected between the support base 41 and the first slider 422. The first slider 422 is fixedly connected to the correction piece 424.

[0027] It can be understood that when the robot places the cover 10, the parameters may not be controlled well and the cover 10 is placed in contact with the correction piece 424. At this time, the correction piece 424 will move downward, the first slider 422 will also move downward, and the first spring 423 will be compressed. Therefore, the correction piece 424 can be moved to protect the cover 10. Placing the cover 10 in hard contact with the correction piece 424 may cause damage to the cover 10, and the correction piece 424 is L-shaped, and the correction piece 424 is higher than the support unit 43. Therefore, the correction piece 424 moves to align the cover 10.

[0028] like Figure 3 As shown, the support unit 43 includes a second sliding sleeve 431 fixedly connected to the support base 41, a second slider 432 slidably connected in the second sliding sleeve 431, a second spring 433 arranged between the support base 41 and the second slider 432, and a support member 434 fixedly connected to the second slider 432, one side of the support member 434 is inclined.

[0029] It is understandable that when the robot is placing the cover 10, the support member 434 will contact the cover 10. During the placement of the cover 10, the support member 434 will slide downward to act as a buffer to prevent the support member 434 from making hard contact with the cover 10 and causing damage to the cover 10.

[0030] like Figure 4 As shown, the synchronization component 8 includes two guide rails 81 arranged on the base plate 1, two sliding seats 82 slidingly connected on the two guide rails 81, and a connecting rod 83 fixedly connected between the two sliding seats 82, and the support seats 41 of the first alignment component 4 and the second alignment component 5 are slidingly connected to the connecting rod 83.

[0031] It can be understood that one of the driving components 9 drives the sliding seat 82 to move on the guide rail 81, the sliding seat 82 drives the connecting rod 83 to move, and the connecting rod 83 drives the first alignment component 4 and the second alignment component 5 to move on the X-axis rail 3.

[0032] like Figure 5As shown, the driving assembly 9 includes two brackets 92 arranged on the base plate 1, two pulleys 93 rotatably connected to the two brackets 92, a flat belt 94 arranged between the pulleys 93, and a motor 91 fixedly connected to the base plate 1, the output shaft of the motor 91 is fixedly connected to one of the pulleys 93, the two X-axis slide rails 3 are respectively fixedly connected to the upper and lower sides of the flat belt 94 of one of the driving assemblies 9, and one of the sliding seats 82 is fixedly connected to the flat belt 94 of the other driving assembly 9.

[0033] It can be understood that the operator can adjust the rotation parameters of the motors 91 of the two drive components 9 through the control system according to the model of the cover 10 to adapt to different models of cover 10. After the adjustment, when the material sensor 11 senses the cover 10, the material sensor 11 controls the motor 91 to rotate according to the parameters in the control system. The rotation of the motor 91 will drive the pulley 93 to rotate, and the pulley 93 drives the flat belt 94 to operate. Since the two X-axis slide rails 3 are distributed and connected to the upper and lower sides of the flat belt 94 of one of the drive components 9, the two X-axis slide rails 3 will move toward each other, and the operation of the flat belt 94 of the other drive component 9 will drive the sliding seat 82 to move along the guide slide rail 81.

[0034] In summary, the two X-axis slide rails 3 move toward each other and drive the support seats 41 thereon to operate toward each other, and the support seat 41 drives the support unit 43 and the alignment unit 42 thereon to move, so that the alignment unit 42 aligns the front and rear sides of the cover plate 10, and the synchronous component 8 moves toward the direction close to the cover plate 10, that is, moves to the left side, and the movement of the synchronous component 8 will drive the support seats 41 of the first alignment component 4 and the second alignment component 5 to move to the left side, and the support units 43 and the alignment units 42 of the support seats 41 of the first alignment component 4 and the second alignment component 5 also move to the left side, and the third alignment component 8 moves to the left side. Component 6 and the fourth alignment component 7 cannot move to the right, thereby aligning the left and right sides of the cover plate 10 to achieve high-precision alignment of the four sides of the cover plate 10. In addition, one side of the support unit 43 is inclined so that the sensor glass portion 102 can be suspended in the air to prevent the sensor glass portion 102 from contacting the support unit 43. When the support unit 43 and the alignment unit 42 align the cover plate 10, the sensor glass portion 102 will not be worn and damaged, and the support length of the support unit 43 can also be increased, so that the robot can easily place the cover plate 10 on the support unit 43.
