[0080] As an improvement, Figure 1-Figure 2 As shown, the X-axis transplanting module 11 includes:

[0081] Fixed seat 111;

[0082] A first guide frame 112 is fixedly connected to the upper end of the fixing base 111;

[0083] A first motor 113 is mounted at one end of the first guide frame 112 . A driving end of the first motor 113 is provided with a first screw rod 1131 extending into the interior of the first guide frame 112 .

[0084] The first slider 114 is disposed outside the first screw rod 1131 and is slidably connected to the inside of the first guide frame 112 for driving the Y-axis transplanting module 12 to adjust its position.

[0085] Further, such as Figure 3 As shown, the Y-axis transplanting module 12 includes:

[0086] A second guide frame 121 is mounted on the upper end of the first sliding block 114;

[0087] The second motor 122 is mounted on one end of the second guide frame 121. A support plate 1121 is provided inside the first guide frame 112 for guiding the movement of the second motor 122. A second screw rod 1211 is installed at the driving end of the second motor 122.

[0088] The second slider 123 is disposed outside the second screw rod 1211 and is used to drive the Z-axis transfer module 13 to adjust its position.

[0089] Furthermore, Figure 5 As shown, the Z-axis transplanting module 13 includes:

[0090] A mounting seat 131 mounted on one end of the second slider 123;

[0091] A third motor 132 is mounted on the upper portion of the mounting base 131 , and a third screw rod 1321 is mounted on the driving end of the third motor 132 ;

[0092] The third slider 133 is disposed outside the third screw rod 1321 and is used to drive the angle adjustment unit 2 to adjust its position.

[0093] It should be added that the fixed seat 111 in the present invention is installed between two conveyor lines, one of which is used to convey the steel sheet 100 at a certain rhythm, and the other conveyor line is used to convey the products to be assembled with the steel sheet 100 at a certain rhythm, and the conveying rhythm of the two conveyor lines is kept consistent; in addition, the lower end of the clamping frame 262 in the present invention is equipped with a clamping claw for clamping and positioning the steel sheet 100.

[0094] It should be noted that: in the specific implementation process of the present invention, Figure 1-Figure 5 As shown, after the clamping frame 262 clamps and positions the steel sheet 100 on the steel sheet conveyor line, the third motor 132 is started, and the third motor 132 drives the third slider 133 to move along the positive direction of the Z axis through the third screw rod 1321. The third slider 133 takes the clamped and positioned steel sheet 100 out of the conveyor line through the angle adjustment unit 2. Subsequently, the second motor 122 is started, and the second motor 122 drives the second slider 123 to move along the second guide frame 121 through the second screw rod 1211. The second slider 123 drives the Z-axis transplanting module 13 along the direction of the Y axis. Move so that the position of the steel sheet 100 on the angle adjustment unit 2 in the Y-axis direction is aligned with the corresponding product to be assembled on the other conveyor line. Finally, start the first motor 113. The first motor 113 drives the first slider 114 to move along the first screw rod 1131 through the first screw rod 1131. The first slider 114 drives the Y-axis transfer module 12 to move along the X-axis direction, so that the position of the steel sheet 100 on the angle adjustment unit 2 in the X-axis direction is aligned with the corresponding product to be assembled on the other conveyor line, completing the orientation adjustment of the steel sheet 100.

[0095] like Figure 5-Figure 8 As shown, then, the angle shifting cylinder 23 is started, and the angle shifting cylinder 23 drives the fourth slider 241 to move along the slide rail 221 through the top block 24, and the fourth slider 241 drives the carrier 261 to rotate through the push shaft 242, and the carrier 261 drives the rotating shaft 264 to rotate in the limiting hole 222 through the rotating rod 263. At the same time, the carrier 261 adjusts the angle of the steel sheet 100 in the clamping and positioning state to be consistent with the direction of the product to be assembled on another conveyor line through the clamping frame 262. Finally, the Z-axis transfer module 13 drives the mounting plate 22 to move downward through the three-dimensional pressure sensor 21, and the mounting plate 22 drives the carrier 261 to move downward through the angle swing limit block 251. The carrier 261 drives the adjusted steel sheet 100 to be pressed down to the upper part of the product to be assembled through the clamping frame 262, completing the assembly of the electronic product steel sheet. The entire assembly process does not require manual participation, and has high assembly efficiency and high assembly accuracy.

[0096] like Figure 5-Figure 6 As shown, in addition, when the clamping frame 262 drives the steel sheet 100 in the clamping and positioning state to be pressed down to the upper part of the product to be assembled, the product to be assembled generates an upward reaction force on the clamping frame 262 through the steel sheet 100, and the clamping frame 262 feeds back the upward reaction force to the three-dimensional pressure sensor 21 through the supporting frame 261 in sequence through the rotating rod 263, the rotating shaft 264, and the mounting plate 22. When the three-dimensional pressure sensor 21 detects that the pressure value of the steel sheet 100 on the product to be assembled reaches an appropriate range, it stops applying pressure to the steel sheet 100. At this time, the Z-axis transfer module 13 is controlled to move upward, and the next group of steel sheets 100 continues to be assembled.
