The second movable plate 140 is rotatably connected to the first movable plate 120. The second driving mechanism 150 is connected to the second movable plate 140 to drive the second movable plate 140 to rotate relative to the first movable plate 120. Specifically, the second driving mechanism 150 of the present embodiment may include an adapter plate 151, a linear motion driving device 152 and a rotation driving device 153. The linear motion driving device 152 is connected to the adapter plate 151 to controllably drive the adapter plate 151 to perform linear motion along a preset direction. The rotation driving device 153 is connected to the adapter plate 151 and the second movable plate 140 , so that when the linear motion driving device 152 drives the adapter plate 151 to move linearly, the second movable plate 140 is driven to rotate by the rotation driving device 153 .

[0073] Specifically, in this embodiment, the first driving mechanism 130 drives the first movable plate 120 to perform linear motion relative to the fixed plate 110 along a preset direction, and the second driving mechanism 150 drives the second movable plate 140 to rotate relative to the first movable plate 120, so that the displacement assembly 100 of this embodiment can adjust the displacement of the object connected to the second movable plate 140 in the preset direction and the angle relative to the fixed plate. Since the first driving mechanism 130 and the second driving mechanism 150 of this embodiment both drive the first movable plate 120 and the second movable plate 140 to move separately, the structure is stable, the movement is smooth, and the debugging is convenient.

[0074] Specifically, the second driving mechanism 150 of this embodiment may include an adapter plate 151, a linear motion driving device 152 and a rotation driving device 153. The linear motion driving device 152 drives the adapter plate 151 to perform linear motion, thereby driving the rotation driving device 153 to rotate, thereby causing the second movable plate 140 to rotate relative to the first movable plate 120, thereby meeting the driving requirements and improving the driving accuracy and stability.

[0075] As a specific embodiment of the present invention, the first driving mechanism 130 of the present embodiment is disposed between the fixed plate 110 and the first movable plate 120 (eg, Figure 1 ) or disposed on the side of the first movable plate 120 (as shown Figure 2 shown).

[0076] Specifically, in this embodiment, the first driving mechanism 130 is disposed between the fixed plate 110 and the first movable plate 120, so that the first driving mechanism 130 can better drive the first movable plate 120. The first driving mechanism 130 is disposed on the side of the first movable plate 120, so that the dimensions of the fixed plate 110 and the first movable plate 120 in the thickness direction can be reduced as much as possible, thereby reducing the occupied area of ​​the mechanism.

[0077] As a specific embodiment of the present invention, Figure 1 and Figure 3 As shown, in this embodiment, at least one slider 111 is provided at the fixed plate 110, a first slide groove 1111 is provided at each slider 111, at least one first slide rail 121 is provided at the first movable plate 120, and each first slide groove 1111 cooperates with one of the first slide rails 121, so that the first movable plate 120 moves along the direction of the first slide rail 121 under the drive of the first driving mechanism 130.

[0078] Specifically, in this embodiment, by providing a first slide groove 1111 and a first slide rail 121 at the fixed plate 110 and the first movable plate 120 , the first movable plate 120 moves along the first slide rail 121 driven by the first driving mechanism 130 , thereby improving the stability of the movement.

[0079] Specifically, the number of the first slide groove 1111 and the first slide rail 121 of this embodiment is the same, and both are multiple. Preferably, the number of the first slide groove 1111 and the first slide rail 121 of this embodiment is two. The two first slide rails 121 are arranged in parallel, and the two first slide rails 121 are spaced a certain distance apart, so as to ensure the stability between the first movable plate 120 and the fixed plate 110. If the first driving mechanism 130 is arranged between the fixed plate 110 and the first movable plate 120, the first driving mechanism 130 can be located between the two first slide rails 121. If the first driving mechanism 130 is arranged on the side of the fixed plate 110 and the first movable plate 120, it is arranged on the side of one of the first slide rails 121. Of course, preferably, when the first driving mechanism 130 is arranged on the side of the first movable plate 120, the number of the first driving mechanism 130 can be two, and each first driving mechanism 130 is arranged on the side of one of the first slide rails 121, so as to further increase the stability of the movement of the first movable plate 120.

[0080] As a specific embodiment of the present invention, Figure 4 As shown, the first driving mechanism 130 of the present embodiment may include a first motor 131, a first lead screw 132, a first nut 133 and a first nut mounting seat 134. Among them, one end of the first lead screw 132 is connected to the first motor 131 to rotate under the drive of the first motor 131. The first nut 133 is sleeved on the first lead screw 132, so that when the first lead screw 132 rotates, the first nut 133 is driven to make a linear motion along the axis of the first lead screw 132. The first nut mounting seat 134 is connected to the first nut 133 and the first movable plate 120, so that when the first nut 133 makes a linear motion, the first movable plate 120 is driven to make a linear motion through the first nut mounting seat 134.

[0081] In this embodiment, the first motor 131 drives the first lead screw 132 to rotate, and the first lead screw 132 and the first nut 133 cooperate with each other to make the first nut 133 do linear motion, thereby driving the first movable plate 120 to do linear motion. By converting the rotational motion of the first motor 131 into the linear motion of the first nut 133, the control accuracy can be improved and the stability of the system can be improved. Specifically, in this embodiment, the first nut mounting seat 134 drives the first movable plate 120 to do linear motion relative to the fixed plate 110. Specifically, the first nut mounting seat 134 is interconnected with the first nut 133, and the first nut mounting seat 134 is also interconnected with the first movable plate 120, so that when the first nut 133 moves, the first nut mounting seat 134 moves, thereby driving the first movable plate 120 to move.

[0082] As a specific embodiment of the utility model, the first driving mechanism 130 of this embodiment may further include a first motor mounting seat 135, a first coupling 136, a first screw fixing seat 137 and a first bearing mounting seat 138. The first motor mounting seat 135 is fixed on the fixing plate 110 and connected to the first motor 131. A first groove 1351 is provided at the first motor mounting seat 135. The first coupling 136 is located at the first groove 1351, and one end is connected to the output end of the first motor 131, and the other end is connected to the first screw 132, so as to transmit the power output by the first motor 131 to the first screw 132. The first screw fixing seat 137 is fixedly connected to the first motor mounting seat 135, and is connected to one end of the first screw 132 through the first bearing 1371.

[0083] The first motor mounting seat 135, the first screw fixing seat 137 and the first bearing mounting seat 138 of this embodiment mainly play the role of fixing the corresponding devices, for example, the first motor mounting seat 135 is used to fix the first motor 131, the first screw fixing seat 137 is used to install and fix the first screw 132, and the first bearing mounting seat 138 is used to install the first bearing 1371 and fix the end of the first screw 132.

[0084] As a specific embodiment of the utility model, the first driving mechanism 130 in this embodiment may include a first linear motor. The first linear motor directly drives the first movable plate 120 to perform linear motion in a preset direction relative to the fixed plate 110, which can simplify the structure. Compared with the above embodiment in which the linear motion power is transmitted through the structure of the first lead screw 132 and the first nut 133, the cost of the first linear motor is higher.

[0085] As a specific embodiment of the present invention, the linear motion driving device 152 of this embodiment is fixedly connected to the first movable plate 120. The linear motion driving device 152 is fixedly connected to the first movable plate 120 so that it can follow the first movable plate 120 to move relative to the fixed plate 110, and then the second movable plate 140 can also follow the first movable plate 120 to move relative to the fixed plate 110.

One end of the second lead screw 1522 is connected to the second motor 1521 to rotate under the drive of the second motor 1521. The second nut mounting seat 1523 is sleeved on the second lead screw 1522, so that the second lead screw 1522 drives the second nut mounting seat 1523 to perform linear motion along the axis of the second lead screw 1522 when rotating.

[0087] Specifically, the linear motion driving device 152 of this embodiment can drive the second nut mounting seat 1523 to perform linear motion along the axis of the second lead screw 1522 through the second motor 1521, thereby driving the rotation driving device 153 to move, and then driving the second movable plate 140 to rotate relative to the first movable plate 120. By converting the rotation of the motor into linear motion, the stability and accuracy of the linear motion can be improved.

[0088] As a specific embodiment of the present invention, Figure 5 As shown, the linear motion driving device 152 of this embodiment may also include a second motor mounting seat 1524, a second coupling 1525, a second lead screw fixing seat 1526 and a second bearing mounting seat 1527. The second motor mounting seat 1524 is fixed on the first movable plate 120 and connected to the second motor 1521, and a second groove 1528 is provided at the second motor mounting seat 1524. The second coupling 1525 is located at the second groove 1528, and one end of the second coupling 1525 is connected to the output end of the second motor 1521, and the other end is connected to the second lead screw 1522, so as to transmit the power output by the second motor 1521 to the second lead screw 1522. The second lead screw fixing seat 1526 is fixedly connected to the second motor mounting seat 1524, and is connected to one end of the second lead screw 1522 through the third bearing 1529. The second bearing mounting seat 1527 is fixed on the first movable plate 120, and is connected to the other end of the second lead screw 1522 through the fourth bearing 155.

[0089] Specifically, in this embodiment, the second motor 1521 and the second lead screw 1522 are connected to the first movable plate 120 through a mounting seat or a fixing seat, which can increase the stability of the linear drive device. The second coupling 1525 can transmit the rotation of the second motor 1521 to the second lead screw 1522, and then transmit it out through the second lead screw 1522.

[0090] As a specific embodiment of the utility model, the displacement assembly 100 of this embodiment may also include a driving mechanism mounting seat 160, one side of which is fixedly connected to the first movable plate 120, and the other side is fixedly connected to the second motor mounting seat 1524 and the second bearing mounting seat 1527, and a second slide rail 161 is provided on the side facing the linear motion driving device 152. A second slide groove (not shown in the figure) is provided on the side of the second nut mounting seat 1523 facing the driving mechanism mounting seat 160, and the second slide groove cooperates with the second slide rail 161 to enable the second nut mounting seat 1523 to move along the direction of the second slide rail 161.

[0091] Specifically, in this embodiment, a driving mechanism mounting seat 160 is provided, and a second slide rail 161 is provided on the driving mechanism mounting seat 160, and a second slide groove is provided on the second nut mounting seat 1523. Through the cooperation between the second slide rail 161 and the second slide groove, the second nut mounting seat 1523 of the linear motion driving device 152 can move along the second slide rail 161 during linear motion, thereby further increasing the stability of the movement.

[0092] Specifically, the positions of the second slide groove and the second slide rail 161 in this embodiment can be interchanged. In other words, the second slide groove is arranged at the driving mechanism mounting seat 160, and the second slide rail 161 is arranged at the second nut mounting seat 1523. The specific positions of the second slide groove and the second slide rail 161 can be designed as needed.

[0093] As a specific embodiment of the present invention, the linear motion driving device 152 of this embodiment may include a second linear motor. Compared with the structure of the lead screw and nut of the linear motion driving device 152, this embodiment directly uses the second linear motor to simplify the mechanism, but the cost is higher.

[0094] As a specific embodiment of the present invention, Figure 6 As shown, the rotation drive device 153 of this embodiment may include a rotating shaft 1531, a fifth bearing 1532 and a connecting assembly 1533. The rotating shaft 1531 is fixedly connected to the adapter plate 151 and moves with the adapter plate 151. The inner ring of the fifth bearing 1532 is connected to the rotating shaft 1531. The connecting assembly 1533 is connected to the outer ring of the fifth bearing 1532 and the second movable plate 140, and rotates together with the outer ring of the fifth bearing 1532. When the linear motion drive device 152 drives the adapter plate 151 to move, the connecting assembly 1533 rotates relative to the rotating shaft 1531, thereby driving the second movable plate 140 to rotate relative to the first movable plate 120.

[0095] Specifically, the rotation driving device 153 of this embodiment is connected to the rotating shaft 1531 through the adapter plate 151, and the rotating shaft 1531 is connected to the inner ring of the fifth bearing 1532, and the outer ring of the fifth bearing 1532 is connected to the connecting assembly 1533, and the connecting assembly 1533 is connected to the second movable plate 140, so that the rotation driving device 153 is driven by the linear motion driving device 152 to drive the second movable plate 140 to rotate relative to the first movable plate 120. Specifically, when the linear motion driving device 152 drives the second nut mounting seat 1526 to move leftward, the second nut mounting seat 1526 drives the adapter plate 151 to move leftward, and at this time, the adapter plate 151 transmits force to the rotating shaft 1531, and the rotating shaft 1531 transmits force to the connecting assembly 1533, and the second movable plate 140 receives the force of the connecting assembly 1533 and rotates clockwise relative to the first movable plate 130. On the contrary, when the linear motion driving device 152 drives the second nut mounting seat 1526 to move rightward, the second movable plate 140 moves counterclockwise relative to the first movable plate 130 .

[0096] Specifically, the adapter plate 151 and the rotating shaft 1531 of this embodiment can be connected to each other through a tension sleeve 1537, so as to ensure that there is no relative rotation between the adapter plate 151 and the rotating shaft 1531. As a specific embodiment of the utility model, the connecting assembly 1533 of this embodiment may include a connecting plate 1534 and at least one third slide rail 1535, wherein the connecting plate 1534 is fixedly connected to the outer ring of the fifth bearing 1532, and the bottom of the connecting plate 1534 includes at least one third slide groove 1536. Each third slide rail 1535 is fixedly connected to the second movable plate 140, and each third slide groove 1536 is clamped at the corresponding third slide groove 1536 so that the connecting plate 1534 moves along the third slide rail 1535.

[0097] Specifically, the second movable plate 140 needs to be driven to rotate after the linear motion of the linear motion driving device 152 is converted into rotation. After the linear motion of the linear motion driving device 152 is transmitted to the rotation driving device 153, the connecting plate 1534 connected to the fifth bearing 1532 will also move relative to the second movable plate 140 through the rotation of the rotating shaft 1531. In this embodiment, the third slide groove 1536 and the third slide rail 1535 cooperate to enable the connecting plate 1534 to be connected to the second movable plate 140, move relative to the second movable plate 140, and drive the second movable plate 140 to rotate relative to the first movable plate 120.

[0098] As a specific embodiment of the present invention, the number of the third sliding grooves 1536 and the third sliding rails 1535 of this embodiment is the same and both are multiple, the multiple third sliding rails 1535 are parallel to each other, and the multiple third sliding grooves 1536 are parallel to each other.

[0099] Specifically, in this embodiment, the number of the third slide grooves 1536 and the number of the third slide rails 1535 are both two, and they are arranged parallel to each other. Each third slide rail 1535 is engaged with the corresponding third slide groove 1536 and moves along the third slide rail 1535 .

[0100] As a specific embodiment of the present invention, a third groove 141 is disposed at the second movable plate 140 of this embodiment, and the rotation driving device 153 is disposed in the third groove 141 .

[0101] Specifically, in this embodiment, the third groove 141 is provided at the second movable plate 140 , and the rotation driving device 153 is provided in the third groove 141 , which can reduce the occupied position of the rotation driving device 153 .

[0102] As a specific embodiment of the present invention, Figure 1-Figure 3 As shown, the displacement assembly 100 of this embodiment may further include a sixth bearing 154, the inner ring of the sixth bearing 154 is connected to the first movable plate 120, and the outer ring is connected to the second movable plate 140, so that the first movable plate 120 and the second movable plate 140 are rotatably connected through the sixth bearing 154. Specifically, the axis of the sixth bearing 154 of this embodiment is parallel to the axis of the fifth bearing 1532.

[0103] Specifically, the structure and operation principle of the displacement assembly 100 of this embodiment are as follows:

[0104] In this embodiment, a first driving mechanism 130 is arranged at the bottom or side of the fixed plate 110. The first motor 131 and the first screw 132 of the first driving mechanism 130 are fixed on the fixed plate 110 through the first motor mounting seat 135 and the first screw mounting seat, and the first screw 132 drives the first nut 133 and the first nut mounting seat 134 to move linearly. The first nut mounting seat 134 is connected to the first movable plate 120, thereby driving the first movable plate 120 to move linearly.

[0105] The second driving mechanism 150 is disposed on the first movable plate 120, and the first movable plate 120 is rotatably connected to the second movable plate 140 via the sixth bearing 154. The linear motion driving mechanism of the second driving mechanism 150 drives the connecting plate 1534 to move, and the connecting plate 1534 drives the rotating shaft 1531 of the rotating driving device 153 to move, and the rotating shaft 1531 is connected to the inner ring of the fifth bearing 1532, and the outer ring of the fifth bearing 1532 is connected to the connecting assembly 1533, and the connecting assembly 1533 is connected to the second movable plate 140, thereby driving the second movable plate 140 to rotate relative to the first movable plate 120 around the axis of the sixth bearing 154.

[0106] Since the second driving mechanism 150 is disposed on the first movable plate 120, when the first driving mechanism 130 drives the first movable plate 120 to perform linear motion relative to the fixed plate 110, the second driving mechanism 150 also follows the first movable plate 120 to perform linear motion relative to the fixed plate 110. Correspondingly, the second movable plate 140 also follows the first movable plate 120 to perform linear motion relative to the fixed plate 110. When the second driving mechanism 150 drives the second movable plate 140 to rotate relative to the first movable plate 120, at this time, there is no relative rotation between the first movable plate 120 and the fixed plate 110, so the second movable plate 140 will also rotate relative to the fixed plate 110 accordingly.

[0107] As a specific embodiment of the present utility model, this embodiment further provides a gantry transport mechanism, which may include the displacement assembly 100 described above.

[0108] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
