[0024] See also Figure 1-8, an embodiment of the utility model provided: a vertical injection molding machine manipulator, comprising a second module 2; the second module 2 comprises a mounting seat 24, and a first telescopic mechanism 20 is provided on the mounting seat 24, and a second telescopic mechanism 21 is provided on the first telescopic mechanism 20; a first wheel seat 210 is provided at one end of the first telescopic mechanism 20, and a second wheel seat 211 is provided at the other end of the first telescopic mechanism 20, and a first belt 26 is further provided between the first wheel seat 210 and the second wheel seat 211; one end of the first belt 26 is connected to the first wheel seat 210, and the first belt 26 passes through the driving wheel 22 provided on the mounting seat 24 and is connected to the second wheel seat 211; a second belt 28 is further provided between the first wheel seat 210 and the second wheel seat 211, one side of the second belt 28 is connected to the second telescopic mechanism 21 through a first fixing plate 27 provided, and the other side of the second belt 28 is connected to the mounting seat 24 through a second fixing plate 29 provided.

[0025] In summary, since the driving wheel 22 causes the first belt 26 to move when it rotates, the first telescopic mechanism 20 moves on the mounting seat 24; the second telescopic mechanism 21 moves on the first telescopic mechanism 20, so that the device can use the driving wheel 22 to complete the synchronous movement of the first telescopic mechanism 20 and the second telescopic mechanism 21, so as to reduce the number of parts and the number of pipelines attached to the parts when the device realizes the telescopic action, thereby simplifying the structure of the device; and the rotation of the driving wheel 22 can synchronously realize the movement of the two telescopic mechanisms, so it can also improve the synchronization of the movement of the two telescopic mechanisms, thereby improving the accuracy of the movement of the device.

[0026] Furthermore, since the mounting seat 24 is also provided with a first driving member 212, the driving wheel 22 is driven to rotate by the first driving member 212, so as to synchronously drive the second telescopic mechanism 21 to slide on the first telescopic mechanism 20 and drive the first telescopic mechanism 20 to slide on the mounting seat 24. Therefore, the first driving member 212 can be used to provide power for the movement of the two telescopic mechanisms; wherein the first driving member 212 is preferably a servo motor.

[0027] Furthermore, since the first wheel seat 210 and the second wheel seat 211 have the same structure, wherein the second wheel seat 211 includes a pulley 213 and a wheel frame 217 for mounting the pulley 213, wherein the pulley 213 and the wheel frame 217 are provided with a slide groove 215 for sliding cooperation, therefore, the tension of the second belt 28 can be adjusted by sliding the pulley 213 in the slide groove 215.

[0028] Specifically, a screw rod 216 is provided on one side of the wheel frame 217, and the screw rod 216 passes through the wheel frame 217 and the pulley 213 and is connected to the provided nut 214. Based on this, tightening the nut 214 causes the pulley 213 to slide in the slide groove 215 to achieve the adjustment of the tension of the second belt 28.

[0029] In addition, since the second telescopic mechanism 21 is further provided with a connecting plate 23, and a mounting hole 25 for mounting a fixture is further provided on the side of the connecting plate 23. Specifically, the mounting holes 25 are provided on the end surface and the side of the connecting plate 23, and different fixtures can be mounted on the connecting plate 23, so as to facilitate the installation and replacement of the fixtures.

[0030] On the basis of the above solution, since the second module 2 is connected to the first module 1, and the first module 1 causes the second module 2 to slide upward or downward along the first module 1, the height of the second module 2 during operation can be freely adjusted, so that the clamp can clamp materials of different heights.

[0031] Specifically, the first module 1 includes a shell 10; wherein the shell 10 is also provided with a movable frame 13 for mounting the mounting seat 24, and the movable frame 13 slides on the shell 10 to allow the second module 2 to slide upward or downward on the first module 1.

[0032] In order to improve the stability and reliability of the second module 2 during movement, a rack 11 is further provided in the shell 10 , and the rack 11 is connected to a second driving member 14 provided on the moving frame 13 , and the second driving member 14 causes the moving frame 13 to slide on the shell 10 .

[0033] Furthermore, a guide rail 12 is further provided in the housing 10 , and the guide rail 12 slidably cooperates with a slider on the moving frame 13 to guide the moving frame 13 to slide on the housing 10 .

[0034] To sum up, when the second driving member 14 is working, the gear on the second driving member 14 rotates on the rack 11, thereby driving the movable frame 13 to slide along the guide rail 12 to achieve the adjustment of the height of the second module 2; at the same time, the cooperation between the gear and the rack 11 can ensure the reliable movement of the second module 2; wherein, the second driving member 14 is preferably a servo motor to ensure the accuracy of the position of the second module 2 when it is displaced.

[0035] In summary, driven by the first driving member 212, the main part of the second module 2 moves forward and enters the injection molding machine to clamp (receive) the material. Then it returns; then, the first module 1 drives the second module 2 to move up and down. Based on this, the two modules of the equipment can run at the same time, and can realize up, down, forward and backward movement. It is suitable for taking materials from products of different heights. No manual adjustment is required, which improves work efficiency. The first module 1 adopts gear transmission, and the second module 2 adopts belt transmission; the belt is preferably a synchronous belt, so high-precision positioning can be achieved.

[0036] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
