[0002] In the field of circuit substrate production, automated processing equipment is generally used for production. The working table of existing circuit substrate processing equipment adopts a smooth plane. During the transmission process of the circuit substrate, considering the compactness of the structure of the processing equipment, the circuit substrate is usually dragged directly on the smooth working table, which will inevitably cause hard friction between the circuit substrate and the table, resulting in scratches on the circuit substrate, which will affect the quality of the circuit substrate at the least and cause the circuit substrate to be scrapped at the worst. In addition, since the circuit substrate processing equipment produces tens of thousands of circuit substrates every day, the insulating coating on the working table will also accelerate the loss over time, and the electrostatic interference in the equipment will also increase accordingly.

[0003] How to reduce the scratches on the circuit substrate and the wear of the work surface caused by dragging the circuit substrate is a technical problem that needs to be solved by those skilled in the art. Summary of the invention

[0028] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0029] like Figure 1-Figure 2 As shown, this embodiment provides a circuit substrate workbench used in circuit substrate processing equipment, the circuit substrate workbench comprises an upper plate 1, a bottom plate 2 and an air blowing device, wherein the upper plate 1 is provided with a plurality of air blowing holes 11, the bottom plate 2 is provided below the upper plate 1 and connected to the upper plate 1, the bottom plate 2 is provided with a plurality of air blowing slots 21, each air blowing slot 21 is connected to a plurality of air blowing holes 11, and the air blowing device is connected to the air blowing slots 21 through an air pipe. When the circuit substrate is dragged above the upper plate 1, the air blowing device supplies air to the air blowing slots 21, and the air is blown out through the air blowing holes 11 to form an air film on the surface of the upper plate 1, and since one air blowing slot 21 is connected to a plurality of air blowing holes 11 at the same time, the thickness of the air film formed is uniform, so that the circuit substrate is in an air floating state on the upper plate 1 and avoids contact with the upper plate 1, and the dragging friction is smaller, so as to avoid scratches on the circuit substrate and wear of the work surface caused by dragging the circuit substrate. In other embodiments of the present invention, only one blowing groove 21 may be provided on the bottom plate 2 , and the blowing groove 21 is connected to all the blowing holes 11 on the upper plate 1 .

[0030] Preferably, the blowing holes 11 are evenly arranged in multiple rows and columns, and multiple blowing holes 11 in the same row or column are connected to the same blowing groove 21, so that the thickness of the air film formed on the upper plate 1 is more uniform, and the extended shape of the blowing groove 21 is more regular, which is convenient for processing.

[0031] Preferably, the circuit substrate workbench includes at least one blowing device, and each blowing device is respectively connected to the blowing air grooves 21 in different areas of the base plate 2, so that the air films in different areas of the circuit substrate workbench can be controlled individually, and a lower-power blowing device can be selected to save gas and electricity and reduce production costs.

[0032] Optionally, the air blowing device may be a centrifugal compressor, a blower or other types of fans.

[0033] Furthermore, a first trigger switch is provided on the upper plate 1 , and the first trigger switch is electrically connected to the air blowing device. The first trigger switch can detect the circuit substrate on the upper plate 1 , and is used to trigger the start of the air blowing device.

[0034] Preferably, the first trigger switch is a photoelectric sensor.

[0035] Furthermore, the circuit substrate workbench can move relative to the circuit substrate processing equipment. Before processing the circuit substrate, the circuit substrate needs to be positioned in a preset position on the upper plate 1 to pre-align the circuit substrate. However, due to the warping of the circuit substrate itself, it is difficult to focus when using visual recognition technology to capture the circuit substrate. Moreover, after the pre-alignment is completed, when the circuit substrate workbench drives the circuit substrate to transfer to the processing station, the circuit substrate is easy to slide relative to the upper plate 1, which reduces the accuracy of the pre-alignment. Therefore, the circuit substrate workbench also includes a vacuum suction device, and a plurality of suction holes 12 are also provided on the upper plate 1. The position of the suction holes 12 on the upper plate 1 corresponds to the pre-alignment position of the circuit substrate. A suction groove 22 is also provided on the bottom plate 2. One suction groove 22 is connected to the plurality of suction holes 12, and the vacuum suction device is connected to the suction groove 22. When the circuit substrate reaches the pre-alignment position, the vacuum suction device draws air through the suction grooves 22 and the suction holes 12, so that the circuit substrate is adsorbed on the upper plate 1. All corners of the circuit substrate are adsorbed and tightly attached to the upper plate 1, avoiding the problem of difficulty in pre-alignment due to warping of the circuit substrate, and also solving the problem of the circuit substrate sliding relative to the upper plate 1.

[0036] Preferably, the air intake holes 12 are evenly arranged in multiple rows and columns, and multiple air intake holes 12 in the same row or column are connected to the same air intake groove 22, so that the adsorption force on the circuit substrate is more uniform, and the extended shape of the air intake groove 22 is more regular, which is convenient for processing.

[0037] Preferably, the circuit substrate workbench includes at least one suction device, each suction device is respectively connected to the suction grooves 22 in different areas of the base plate 2, so that the adsorption of the circuit substrate in different areas on the circuit substrate workbench can be controlled separately, and a suction device with lower power can be selected to save gas and electricity and reduce production costs.

[0038] Optionally, the suction device may adopt a dry pump, an oil pump or other types of small vacuum pumps.

[0039] Furthermore, a second trigger switch is provided on the upper plate 1, and the second trigger switch is electrically connected to the suction device. The second trigger switch can detect the circuit substrate in the pre-positioning area on the upper plate 1, and is used to trigger the suction device to start. Furthermore, the second trigger switch is also electrically connected to the blowing device. When the second trigger switch detects the circuit substrate, the corresponding blowing device is triggered to close, so that the blowing holes in the pre-positioning area no longer blow out gas to form an air film. Of course, during pre-positioning, all blowing devices can also be closed, so that the air film on the entire upper plate 1 disappears, further reducing the impact of airflow on pre-positioning.

[0040] Preferably, the second trigger switch adopts a photoelectric sensor.

[0041] Furthermore, the circuit substrate workbench also includes a control component, which is electrically connected to the first trigger switch, the second trigger switch, the blowing device and the suction device. The control component can be a centralized or distributed controller. For example, it can be a single microcontroller, such as an STM32 microcontroller, or it can be composed of multiple distributed microcontrollers. The control program can be run in the microcontroller to control the first trigger switch, the second trigger switch, the blowing device and the suction device electrically connected to it to realize their functions.

[0042] Preferably, the upper plate 1 is arranged in a split manner, including three upper plate components on the same plane, and the bottom plate 2 is also arranged in a split manner accordingly, including three bottom plate components on another plane. The three upper plate components are connected to the three bottom plate components one by one, and each upper plate component and bottom plate component can be installed and disassembled separately, which is convenient for maintenance and adjustment of the air tightness between the upper plate 1 and the bottom plate 2.

[0043] Furthermore, a plurality of upper plate reserved holes 13 are provided on the upper plate 1, and a plurality of lower plate reserved holes 23 are provided on the bottom plate 2. The positions of the plurality of upper plate reserved holes 13 and the plurality of lower plate reserved holes 23 correspond one to one, and installation positions are reserved for the first trigger switch, the second trigger switch, the cylinder, the motion guide rail and other components.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
