Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a linear motor manipulator.

[0021] Please see Figure 1-2 A linear motor manipulator includes a support 1, a forward / backward moving assembly 2 mounted on the support 1, and a vertical moving assembly 3 mounted on the forward / backward moving assembly. The forward / backward moving assembly 2 includes a mounting plate 21, a stator 22, a mover 23, a slide rail 24, and a slider 25. The mounting plate 21 is mounted on the support 1, the stator 22 is mounted in the middle of the mounting plate 21, the slide rail 24 is mounted on both sides of the mounting plate 21, the mover 23 is mounted on the stator 22, and the slider 25 is mounted on the slide rail 24. Movable plates 26 are mounted on the slider 25 and the mover 23. A grating ruler 27 is provided on the mounting plate 21, and a reading head mounting plate 28 is provided on the movable plate 26. A reading head 29 is provided on the lower side of the reading head mounting plate 28 and is mounted on the grating ruler 27. Limiting blocks 281 are provided on the front sides of both ends of the mounting plate 28, and buffer pads 261 corresponding to the limiting blocks 281 are provided on both sides of the movable plate 26. A housing 20 is provided on the outer side of the forward / backward moving assembly 2.

[0022] The linear motor manipulator of this utility model mainly includes a support 1, a front-to-back moving component 2, and a vertical moving component 3. The support 1 serves to support and fix the manipulator; the front-to-back moving component 2 is used to drive the manipulator to move left and right; and the vertical moving component 3 is used to drive the manipulator 4 to move up and down, thereby realizing the dual-axis motion of the manipulator.

[0023] Specifically, the forward and backward moving assembly 2 includes a mounting plate 21, a stator 22, a mover 23, a slide rail 24, a slider 25, and a movable plate 26. The mounting plate 21 is vertically mounted on the top of the bracket 1 for mounting and fixing. The stator 22 and the mover 23 form a linear motor, mounted on the front side of the mounting plate 21, to drive the up and down moving assembly 3 forward and backward. The slide rail 24 and the slider 25 are also located on the front side of the mounting plate 21. When the mover 23 reciprocates on the stator 22, it drives the slider 25 to move on the slide rail 24. The movable plate 26 is mounted on the slider 25 and the mover 23 for mounting the motor mounting plate. 31; By setting a grating ruler 27 on the upper side of the mounting plate 21 and a reading head 29 on the movable plate 26, it is ensured that the distance of the back-and-forth movement of the moving part 3 driven by the mover 23 can be measured, which plays a measurement feedback role and further ensures the accuracy of the robot's movement; By setting limit blocks 281 at both ends of the mounting plate 28 and buffer pads 261 on both sides of the movable plate 26, the maximum stroke of the back-and-forth movement of the moving part 3 is further ensured, and the buffer pads 261 prevent the parts from impacting and damaging the mechanism; By setting a protective shell 20 on the outside of the back-and-forth movement part 2, the back-and-forth movement part 2 is protected.

[0024] Please see Figure 1-2 The vertical movement assembly 3 of the linear motor robot includes a motor mounting plate 31, a servo motor 32, a cam bearing follower 33, a follower plate 34, a fixing block 35, and a slide rod 36. The motor mounting plate 31 is mounted on the movable plate 26, and the servo motor 32 is mounted on the motor mounting plate 31. The output shaft of the servo motor 32 is connected to the cam bearing follower 33. One end of the cam bearing follower 33 is placed in the groove 341 of the follower plate 34. The follower plate 34 is connected to the top of the slide rod 36. The fixing block 35 is located on the front side of the motor mounting plate 31, and the slide rod 36 is placed in the groove of the fixing block 35. The lower end of the slide rod 36 is connected to the robot 4. The follower plate 34 has a T-shaped structure, and the groove 341 has a square structure. The two ends of the groove 341 are set as arc surfaces to adapt to the outer wall of the cam bearing follower 33.

[0025] Specifically, the vertical movement component 3 includes a motor mounting plate 31, a servo motor 32, a cam bearing follower 33, a follower plate 34, a fixing block 35, and a slide rod 36. The motor mounting plate 31 is used to fix the servo motor 32 and the fixing block 35. The servo motor 32 is used to drive the cam bearing follower 33 to swing left and right. The lower end of the cam bearing follower 33 is installed in the groove 341 of the follower plate 34. When the cam bearing follower 33 swings left and right, it will drive the slide rod 36 to move up and down in the groove in the middle of the fixing block 35. At the same time, it will drive the robot arm 4 at the lower end of the slide rod 36 to move up and down, realizing the vertical movement of the robot arm. By setting the groove 341 to be square, the lower end of the cam bearing follower 33 is placed in the groove 341, so that the cam bearing follower 33 can swing left and right under the drive of the servo motor 32. During the left and right swing, the follower plate 34 will move up and down, realizing the vertical movement of the robot arm 4.

[0026] The linear motor manipulator of this invention achieves vertical movement of the manipulator through the vertical movement component 3 and forward and backward movement of the manipulator through the forward and backward movement component 2, ensuring the flexibility of the manipulator's dual-axis movement, making the manipulator's stroke larger, its application range wider, and enriching the application scenarios of the manipulator.
