The movable workbench devices are arranged on two sides, so that the rapid and stable clamping process can be ensured; the clamping rods 9 are oppositely arranged, so that the workpiece can be effectively driven to rotate around the rods.
It is added that the above only describes the necessary components of the mobile table device, in the actual use case corresponding auxiliary elements are required to provide sufficient support force to ensure the feasibility of the device.

In this embodiment, the end of the gripping rod 9 is provided with a detachable jacket 91 to cope with workpieces with different curved surfaces; the working end surface of the collet 91 is of a non-planar configuration to increase the contact point with the workpiece.
Specifically, as shown in fig. 4, when it is required to clamp an object with a circular arc end, such as a bottle cap end of a cosmetic bottle, a jacket 91 with a concave arc end face is used, the jacket can clamp a processed object better and more firmly, the increase of the contact surface makes the working effect of the clamp better, and at the same time, the position of the workpiece can be corrected to a certain extent, the problem of pattern inclination caused by improper position is reduced, and thus a better printing effect is obtained.

From the above, the utility model is not only suitable for workpieces with regular shapes such as cylinders, planes and the like, but also can be used for revolving bodies with various irregular shapes. However, when handling the latter, such as a vase with a wide bottom and a narrow top, the workpiece is often placed on the conveyor belt 251 obliquely, and the two opposite gripping bars 9 are operated at the same height, so that the workpiece cannot be leveled during gripping, which easily results in problems such as improper alignment of the workpiece, and even large deviation of printing effects.
In view of the above, the present utility model provides different forms of conveyor belts.
As shown in fig. 6, when it is necessary to convey an object that is easy to grip, such as a rectangular parallelepiped, a cylindrical shape, or the like, we use a conveyor belt 251 that is horizontally arranged; as shown in fig. 7, when it is necessary to convey the revolution bodies having unequal upper and lower end areas, a combination of different diameters of the driving roller and the driven roller may be adopted to present a belt 251 inclined in the advancing direction, thereby ensuring that the revolution bodies remain horizontal all the time; in addition, the transmission belt 251 can also adopt a separated caterpillar structure to replace a conventional roller, so that the transmission surface is more attached to a special curved surface of a workpiece, and the structure has strong replaceability and can be more suitable for the workpiece with a special shape. In specific embodiments, more types of belts 251 can be used, and the revolving body can be kept in a horizontal state for clamping, so the specific structure of the belts 251 is not specifically limited herein.
The spray head support 24 is erected above the conveyor belt 251, the spray head support 24 is in an inverted U-shaped structure, two sides of the spray head support 24 are respectively and fixedly connected with the oppositely arranged bottom frame 20, the upper parts of the two sides are connected into a whole through two transverse plates, the transverse plates are positioned right above the conveyor belt 251, diffuse reflection type infrared photoelectric sensors (not shown in the figure) are arranged on the transverse plates, the embodiment adopts the E18-D80NK model, as shown in fig. 8, the infrared photoelectric sensors are provided with a pair of infrared emission and receiving pipes, the emitted light is emitted after modulation and is emitted to the appointed position of the top surface of the conveyor belt 251, when the detection direction meets an obstacle, the infrared light is received by the receiving pipe, the received light beam (light energy) is converted into current to be transmitted to an integrated circuit, the current is amplified by an amplifier and then output, and a digital signal (a low-level signal) is output, and meanwhile, an indicator lamp at the tail of the sensor can be lightened.
When an obstacle is detected, namely that the workpiece to be printed reaches the position between the two movable workbench devices, the infrared photoelectric sensor sends a digital signal to a control system of the device, and the control system randomly starts related operation devices to realize clamping and printing operations on the workpiece.
Further, as shown in fig. 9, a linear sliding rail 23 is set between the two transverse plates along the width direction of the driving belt, a matched linear motor 26 is disposed on the linear sliding rail 23, and a UV nozzle (not shown in the figure) is fixedly mounted on the outer wall of the linear motor 26. The nozzle support 24, the linear slide rail 23, the linear motor 26 and the UV nozzle form a UV printer nozzle device 22, wherein the linear motor 26 and the UV nozzle are electrically connected with the control system. As can be seen from the arrangement of the linear slide 23, the UV spray head can perform displacement variation along the width direction of the conveyor belt 251 under the command of the control system, and UV printing is performed in cooperation with the rotation of the object clamped by the clamping device.
In this embodiment, in order to realize fully automatic gripping of the workpiece to be printed for pipelining and to save costs as much as possible, we use an embedded technology based on a 51-singlechip as a solution. An STC89C52RC singlechip is adopted as a core controller of the control system, and an infrared identification sensor module and a power supply module are assisted. The clock circuit in the singlechip can provide accurate time signals, and the infrared sensor can transmit signals whether an object passes through the clamping position. The singlechip is combined with the data of the hardware signals and analyzed through the software programming of the singlechip, so that the photoelectric timing switch for timing and infrared light identification is realized, the machine can accurately identify the workpiece to be printed in the same time interval, and the clamping is automatically carried out.
The working process of the device is briefly described in combination with the structural composition of the device:
the workpiece is conveyed to the lower part of the UV spray head through the conveyor belt 251, when the workpiece is conveyed to a designated area through the conveyor belt 251 and is identified by the infrared photoelectric sensor, the control system is prompted to send a switch instruction to enable the transverse hydraulic cylinder 10 and the longitudinal hydraulic cylinder 21 of the movable workbench device to work, then the clamping and lifting of the workpiece are completed in a matched mode, the control system sends an instruction again to control the rotating motor 1 to rotate, and the spraying speed of printing is matched with the UV spray head to rotate, so that the printing operation is completed. The whole process only needs to manually set the printing position and parameters in advance, and the device can realize automatic identification printing in the follow-up process. The control procedure in the process can be seen in fig. 10.
