[0002] The alignment platform is a precise positioning device based on a three-dimensional coordinate system, which can move to any position in space to complete the correction work;

[0003] The current UVW visual alignment platform cannot adjust displacement in different directions according to work requirements, thus failing to meet daily work requirements and reducing the performance of the UVW visual alignment platform;

[0004] The existing patent (Announcement No.: CN214265488U) discloses a precise UVW visual alignment platform, including a base, a main X-axis driven module, a main Y-axis driven module, a secondary X-axis driven module, a secondary Y-axis driven module, a workbench, an X-axis motor and other structures. By setting mutually intersecting driven modules between the base and the workbench, X-axis and Y-axis movement can be achieved, and displacement adjustment can be performed in different directions according to work requirements, thereby improving the performance of the UVW visual alignment platform;

[0005] However, during the operation of the workbench, the motor will generate a certain amount of heat after continuous work. When the heat accumulation of the motor is serious, the different thermal expansion coefficients of various parts inside the stepper motor will lead to changes in structural stress and slight changes in the internal air gap, which will affect the dynamic response of the stepper motor and cause the motor to lose steps. At the same time, when the temperature is high, it will also cause the motor to demagnetize. Utility Model Content

[0006] The purpose of the present application is to provide a 3-axis vision alignment workbench to solve the problem of motor losing steps due to heat generated by continuous operation of the motor as mentioned in the above background technology.

[0007] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a 3-axis visual alignment workbench, comprising a base, a driving mechanism connected to one side of the base and a work surface connected to the driving mechanism, and also comprising a heat dissipation mechanism fixedly connected to the side adjacent to the base and the driving mechanism, and the heat dissipation mechanism comprises a heat-conducting shell wrapped around the outer surface of the heat source and conducting heat, heat dissipation fins integrally formed on the outer surface of the heat-conducting shell and in contact with the air, and two fans fixedly connected to one side of the base and symmetrically located on both sides of the heat-conducting shell.

A circulating pump is also fixedly connected to one side of the base, and the input end and the output end of the circulating pump are respectively connected to the liquid inlet and the liquid outlet through metal pipes.

[0009] In one embodiment, the heat dissipation fins are integrally formed on both sides of the heat-conducting housing, and the heat-conducting housing is fixed to the base by bolts.

[0011] In one embodiment, a bearing is provided inside the support seat, and the output shaft of the motor passes through the inner ring of the bearing and is fixedly connected to the screw rod.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] The present application uses a fan to dissipate heat from the motor to prevent the motor torque from decreasing or being demagnetized due to high temperature. At the same time, a flow channel is opened inside the heat-conducting shell, and the heat-conducting shell and the motor are cooled by liquid cooling to achieve better control of the motor temperature.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] Example:

[0022] See also Figure 1-3 The present application provides a technical solution: a 3-axis visual alignment workbench, comprising a base 1, a driving mechanism 3 connected to one side of the base 1 and a work surface 2 connected to the driving mechanism 3, and also comprising a heat dissipation mechanism 4 fixedly connected to the side adjacent to the base 1 and the driving mechanism 3, and the heat dissipation mechanism 4 comprises a heat-conducting shell 41 wrapped around the outer surface of the heat source and conducting heat, a heat dissipation fin 42 integrally formed on the outer surface of the heat-conducting shell 41 and in contact with air, and two fans 43 fixedly connected to one side of the base 1 and symmetrically located on both sides of the heat-conducting shell 41, and the heat dissipation fins 42 are integrally formed on both sides of the heat-conducting shell 41, and the heat-conducting shell 41 is fixed to the base 1 by bolts; the heat of the heat source can be conducted to the heat-conducting shell 41, and the heat-dissipating fins 42 can increase the contact area with the air, and dissipate the heat of the heat-conducting shell 41 more quickly, and the two fans 43 are respectively located on both sides opposite to each other, and the fan 43 on one side of the fan works to blow air to the heat-dissipating fins 42, and the fan 43 on the other side works to extract the airflow blown from the heat-dissipating fins 42, clamping the heat-dissipating fins 42 and the air flow around the heat-conducting shell 41 to improve the heat dissipation efficiency.

[0023] See also Figure 3In this embodiment, a flow channel 46 is further provided inside the heat-conducting shell 41, and a liquid inlet and a liquid outlet connected to the flow channel 46 are provided on the outer surface of the heat-conducting shell 41. A circulation pump 45 is further fixedly connected to one side of the base 1, and the input end and the output end of the circulation pump 45 are respectively connected to the liquid inlet and the liquid outlet through the metal pipe 44. The water-cooling liquid is pumped from the liquid inlet into the flow channel 46 through the circulation pump 45. The water-cooling liquid flows in the flow channel 46 to take out the heat on the heat-conducting shell 41. When the water-cooling liquid is discharged from the flow channel 46 and enters the metal pipe 44, the fan 43 can blow air to cool the metal pipe 44 to achieve cooling of the water-cooling liquid. The cooled water-cooling liquid enters the circulation pump 45 and is pumped into the flow channel 46 again. The water-cooling and air-cooling effects are better.

A wire groove is opened in the part, and a wire rod 38 is screwed in the wire groove. The wire rod 38 is fixedly connected to the output shaft of the motor 31 at one end away from the slide seat 33. The motor 31 can drive the wire rod 38 to rotate when it is working, and the slide seat 33 is driven to slide on the slide rail 34 through the rotation of the wire rod 38. It can be seen from the figure that the installation directions of the four motors 31 are different.
