[0031] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0032] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] In one embodiment of the present application, a dual linear module drive mechanism is disclosed, such as Figure 1-Figure 2As shown, the drive mechanism includes a drive motor 1, a speed distributor, a first transmission unit, a first linear module 2, a second transmission unit and a second linear module 3. The first transmission unit is arranged on the first linear module 2, and the second transmission unit is arranged on the second linear module 3.

[0034] The first linear module 2 and the second linear module 3 are arranged in parallel. A linear moving unit is respectively provided in the first linear module 2 and the second linear module 3. The linear moving unit is used to drive the external execution structure to move.

[0035] The driving motor 1 transmits power to the first transmission unit and the second transmission unit respectively through the speed distributor. The first transmission unit drives the linear moving unit connected to the first linear module 2, and the second transmission unit drives the linear moving unit connected to the second linear module 3.

[0036] In summary, in the dual linear module drive mechanism of this embodiment, the driving motor transmits power to the first transmission unit and the second transmission unit respectively through the speed distributor, and then the first transmission unit drives the linear moving unit connected to the first linear module, and the second transmission unit drives the linear moving unit connected to the second linear module, so that one driving motor drives the synchronous movement of dual parallel linear modules, reducing the manufacturing cost of the dual linear modules and the difficulty of writing the driving motor control program.

[0037] In one embodiment, the speed distributor is a reducer 4, such as Figure 2-Figure 3 As shown, the reducer 4 is specifically a T-type reducer, the input shaft of the reducer 4 is transmission-connected to the drive motor 1, one output shaft of the reducer 4 is transmission-connected to the first transmission unit, and the other output shaft is transmission-connected to the second transmission unit, thereby distributing the power of the drive motor 1 to the two transmission units.

[0038] like Figure 1-Figure 2 As shown, the second transmission unit includes a transmission shaft 5, which is arranged between the two linear modules. The second transmission unit is connected to the reducer 4 through the transmission shaft 5, thereby realizing that the drive motor 1 synchronously drives the first transmission unit and the second transmission unit. Of course, the first transmission unit can also include a transmission shaft, and the first transmission unit is connected to the reducer through the transmission shaft, or the first transmission unit and the second transmission unit each include a transmission shaft, so that the first transmission unit and the second transmission unit are connected to the reducer through the transmission shaft.

[0039] In one or more embodiments, Figure 1-Figure 2 As shown, the first transmission unit includes a first corner box 6, and the second transmission unit further includes a second corner box 7. The first corner box 6 and the second corner box 7 are used to change the power transmission direction of the first transmission unit and the second transmission unit respectively.

[0040] The specific connection method is: one output shaft of the reducer 4 is transmission connected to the input shaft of the first corner box 6, and the output shaft of the first corner box 6 is transmission connected to the first linear module 2; one end of the transmission shaft 5 is transmission connected to the input shaft of the second corner box 7, and the output shaft of the second corner box 7 is transmission connected to the second linear module 3.

[0041] There are two power transmission paths in the dual linear module drive mechanism of this embodiment. One path is: the driving motor 1 passes through the reducer 4 and the first corner box 6 in sequence to transmit power to the linear moving unit of the first linear module 2; the other path is: the driving motor 1 passes through the reducer 4, the transmission shaft 5 and the second corner box 7 in sequence to transmit power to the linear moving unit of the second linear module 3.

[0042] In one embodiment, Figure 2 As shown, the second transmission unit further includes a connecting shaft 8 .

[0043] The ends of the connecting shaft 8 are respectively connected to one end of the transmission shaft 5 and the input shaft of the second corner box 7. The assembly sequence of the dual linear module drive mechanism is: first, assemble the first corner box 6 onto the first linear module, then the second corner box 7 onto the second linear module, then assemble the reducer 4 and drive motor 1, and finally, the transmission shaft 5. Without the connecting shaft 8, the transmission shaft 5 would need to be directly connected to the input shaft of the second corner box 7, making assembly of the transmission shaft 5 inconvenient. Providing the connecting shaft 8 between the transmission shaft 5 and the second corner box 7 facilitates the final assembly of the transmission shaft 5.

[0044] In one embodiment, Figure 1-Figure 2 As shown, the first transmission unit and the second transmission unit further include a first coupling 9 and a second coupling 10, respectively.

[0045] An output shaft of the reducer 4 is fixedly connected to one end of the transmission shaft 5 through the first coupling 9, and the other end of the transmission shaft 5 is fixedly connected to the connecting shaft 8 through the second coupling 10, thereby achieving relative fixation of the transmission shaft 5 with the connecting shaft 8 and an output shaft of the reducer 4 respectively.

[0046] In one embodiment, the driving motor 1 is a servo motor, which drives the first linear module and the second linear module through the servo motor, thereby achieving precise control of the displacement of the linear moving unit.

[0047] In one or some embodiments, the first corner box 6 and the second corner box 7 are respectively fixed to the ends of the first linear module 2 and the second linear module 3 by screws or bolts.

[0048] The reducer 4 is fixedly connected to the first corner box 6 by screws or bolts.

[0049] The screw is preferably a hexagonal screw.

[0050] In one or more embodiments, Figure 3 As shown, the linear moving unit of the first linear module 2 includes a first transmission belt, a first driving shaft 11 and a first driven shaft. The first transmission belt is sleeved on the first driving shaft 11 and the first driven shaft. The first driving shaft 11 is connected to the output shaft of the first corner box 6 to drive the first transmission belt to rotate. Figure 3 Only the transmission structure of the first corner box 6 and the linear moving unit of the first linear module 2 is shown. Those skilled in the art will understand that the transmission structure of the second corner box 7 and the linear moving unit of the second linear module 3 is symmetrical thereto.

[0051] The linear moving unit of the second linear module 3 includes a second transmission belt, a second driving shaft and a second driven shaft. The second transmission belt is sleeved on the second driving shaft and the second driven shaft. The second driving shaft is transmission-connected to the output shaft of the second corner box 7 to drive the second transmission belt to rotate.

[0052] Of course, the linear moving unit may be a screw rod, a rack or other transmission structures, which are also within the protection scope of this application.

[0053] In one embodiment, the driving mechanism further includes a third coupling and a fourth coupling.

[0054] The output shaft of the first corner box 6 is fixedly connected to the first drive shaft 11 via a third coupling, and the output shaft of the second corner box 7 is fixedly connected to the second drive shaft via a fourth coupling.

[0055] In one embodiment, Figure 1 As shown, a plurality of fixing seats 12 are fixedly provided at corresponding positions on the first and second transmission belts to fix an external actuator, thereby enabling the external actuator to move through the first and second transmission belts. The external actuator can be an actuator device such as a robotic arm. The number and position of the fixing seats 12 can be set as needed.

[0056] The above description is only a specific embodiment of the present invention. Based on the above teachings of the present invention, those skilled in the art may make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above description is only a better explanation of the purpose of the present invention, and the scope of protection of the present invention shall be based on the scope of protection of the claims.
