[0025] In related technologies, drive components 400 are installed at both ends of the frame 100 to support and drive the support beam 200, and a guide rail is installed in the middle for guidance. The span of the support beam 200 at both ends is too large, and its own weight causes severe deformation in the middle, which in turn presses downwards against the guide rail 420. This ultimately leads to jamming or impaired movement when the support beam 200 and the frame 100 slide relative to each other. Simultaneously, the deformation in the middle of the support beam 200 causes positional errors in the processing unit 300, thus affecting processing accuracy.

[0026] Please refer to Figure 1 and Figure 2In view of the deficiencies in the aforementioned related technologies, according to a first aspect of the embodiments of this application, a gantry structure is provided, comprising a frame 100, a support beam 200, and a drive assembly 400. The frame 100 is used to support a workpiece; the support beam 200 is disposed above the frame 100; the drive assembly 400 is disposed between the frame 100 and the support beam 200, and is used to support and drive the support beam 200; the workpiece is a circuit board or other component; and the processing assembly is used to perform drilling, forming, or other processing operations on the workpiece.

[0027] Please continue to refer to Figure 1 The gantry structure includes at least two drive assemblies 400, and the support beam 200 has at least two connecting parts. Both drive assemblies 400 are located between the frame 100 and the support beam 200, used to drive the support beam 200 to move relative to the frame 100, ensuring drive efficiency and stability. One side of each drive assembly 400 is mounted to the frame 100, and the other side is connected to the connecting part; wherein the minimum distance from at least one connecting part to both ends of the support beam 200 is greater than zero.

[0028] In the embodiments of this application, at least one of the multiple connecting parts has a minimum distance greater than zero from both ends of the support beam 200. That is, compared to the prior art, the embodiments of this application redesign at least one connecting part originally located at the ends of the support beam 200 to be located in the middle of the support beam 200, thereby shortening the span between adjacent connecting parts and reducing the deformation of the middle part of the support beam 200. This reduces the deformation of the middle part of the support beam 200, making its sliding with the guide rail 420 smoother. Simultaneously, it also reduces the positional error of the processing unit 300 on the support beam 200, improving processing accuracy.

[0029] It should be noted that the driving assembly may include a driving component and a guiding component, such as a guide rail slider assembly. Both the driving component and the guiding component are connected to the support beam 200, and the driving component and the guiding component are arranged side by side. The support beam 200 has a first end and a second end. Taking the distance from the connecting part to the first end of the support beam 200 as an example, in the extension direction of the support beam 200, if the guiding component is closer to the first end of the support beam 200, then the minimum distance from the connecting part to the first end of the support beam 200 should be understood as the distance from the guiding component to the first end of the support beam 200; if the driving component is closer to the first end of the support beam 200, then the minimum distance from the connecting part to the first end of the support beam 200 should be understood as the distance from the driving component to the first end of the support beam 200.

[0030] Please continue to refer to Figure 1In one embodiment, among the multiple connecting parts, there are two outermost connecting parts, and the minimum distance from both connecting parts to the two ends of the support beam 200 is greater than zero. That is, the two outermost connecting parts are moved inward a certain distance towards the middle of the support beam 200, further shortening the span between the two outermost connecting parts, thereby further reducing the deformation of the middle of the support beam 200.

[0031] Specifically, the support beam 200 has a first end and a second end disposed opposite to each other, and the support beam 200 is provided with a first connecting portion and a second connecting portion; the drive assembly 400 includes a first drive assembly and a second drive assembly, the first drive assembly being connected to the first connecting portion and the second drive assembly being connected to the second connecting portion; wherein, the minimum distance from the first connecting portion to both the first end and the second end is greater than zero, and the minimum distance from the second connecting portion to both the first end and the second end is also greater than zero. That is, both the first connecting portion and the second connecting portion are located in the middle of the support beam, between the first end and the second end, thereby shortening the span between the first connecting portion and the second connecting portion, and thus reducing the deformation of the middle part of the support beam 200.

[0032] In another embodiment, the support beam 200 has a first end and a second end disposed opposite to each other, and the support beam 200 is provided with a first connecting portion and a second connecting portion; the drive assembly 400 includes a first drive assembly and a second drive assembly, the first drive assembly being connected to the first connecting portion and the second drive assembly being connected to the second connecting portion; wherein, the minimum distance from the first connecting portion to the first end is equal to zero, and the minimum distance from the second connecting portion to both the first end and the second end is greater than zero. That is, the first connecting portion is located at the first end, and the second connecting portion moves inward a certain distance from the second end, thereby shortening the span between the first connecting portion and the second connecting portion, thereby also reducing the deformation of the middle part of the support beam 200.

[0033] In another embodiment, the support beam 200 has a first end and a second end disposed opposite to each other, and the support beam 200 is provided with a first connecting portion, a second connecting portion and a third connecting portion; the drive assembly 400 includes a first drive assembly, a second drive assembly and a third drive assembly, the first drive assembly is connected to the first connecting portion, the second drive assembly is connected to the second connecting portion, and the third drive assembly is connected to the third connecting portion; wherein, the minimum distance from the first connecting portion to the first end is equal to zero, the minimum distance from the third connecting portion to the second end is equal to zero, and the minimum distance from the second connecting portion to both the first end and the second end is greater than zero.

[0034] Specifically, the drive assembly 400 is provided with at least three components: a first drive assembly, a second drive assembly, and a third drive assembly. The support beam 200 is provided with at least three connecting parts: a first connecting part, a second connecting part, and a third connecting part. The first connecting part and the third connecting part are located at both ends of the support beam 200, respectively, while the second connecting part is located at any position between the two ends of the support beam 200. In this way, the middle part of the support beam 200 can also be supported, reducing the deformation of the middle part of the support beam 200.

[0035] In one embodiment, the minimum distance from the first connecting part to the first end is a, the minimum distance from the second connecting part to the second end is b, and the minimum distance from the first end to the second end is c, and satisfies: 0.18≤a / c≤0.35; and / or, 0.18≤b / c≤0.35.

[0036] It is understandable that the ratio of the minimum distance 'a' from the first connecting part to the first end to the length 'c' of the support beam 200, or the ratio of the minimum distance 'b' from the second connecting part to the second end to the length 'c' of the support beam 200, depends on various factors such as the length, weight, and weight distribution of the support beam 200. Depending on different needs, this ratio can be set to any value between 0.18 and 0.35, such as 0.18, 0.20, 0.25, 0.28, 0.30, 0.32, and 0.35.

[0037] Following the above, shortening the span of the two connecting parts is essentially to ensure that the weight of the support beam 200 located between the connecting part and the end of the support beam 200 is roughly balanced with the weight of the support beam 200 located between the two connecting parts. When this ratio is less than 0.18, it can be understood that the inward displacement of the connecting part is small, and the weight of the support beam 200 located between the end and the connecting part is too small to balance the weight located between the two connecting parts, thus making it difficult to achieve the technical effect of reducing the deformation of the middle part of the support beam 200. When this ratio is greater than 0.35, it can be understood that the inward displacement of the connecting part is too large, and the weight of the support beam 200 located between the end and the connecting part is too large, which may cause the middle part of the support beam 200 to arch upward. Therefore, setting a / c and / or b / c between 0.18 and 0.35 can reduce the downward deformation of the middle part of the support beam 200 and also prevent the middle part of the support beam 200 from arching upward.

[0038] In one embodiment, the minimum distance 'a' from the first connecting part to the first end and the distance 'b' from the second connecting part to the second end also satisfy: a = b. That is, the inward movement distances of the two connecting parts are equal, so that the two connecting parts can be symmetrical about the center of the support beam 200, thereby making the force on the two connecting parts more uniform, so as to support them more stably on the frame 100, and the movement posture of the support beam 200 relative to the frame 100 is more stable.

[0039] In another embodiment, since other components such as electrical control facilities are also provided on the support beam 200, it is difficult to distribute the weight of these components evenly on the support beam 200. Therefore, the inward displacement distances of the two connecting parts can also be set to be unequal. For example, the weight of the left side of the support beam 200 may be greater than that of the right side, causing the center of gravity of the entire processing assembly to shift to the left. Therefore, it is necessary to make the inward displacement distance of the left connecting part smaller and the inward displacement distance of the right connecting part larger in order to balance the weight on both sides.

[0040] In one embodiment, the drive assembly 400 includes a drive member 410 and a guide rail 420. The drive member 410 and the guide rail 420 are arranged side by side. The drive member 410 is used to drive the support beam 200 to move relative to the frame 100. A slider 430 is provided at the connection portion of the support beam, and the slider 430 is slidably disposed on the guide rail 420. Exemplarily, the drive member 410 can be configured as a motor, cylinder, hydraulic cylinder, or magnetic drive, etc. The guide rail 420 located on the side of the drive member 410 not only serves a guiding function, but more importantly, it serves a supporting function to support the support beam 200 above the frame 100. It should be noted that when two sliders 430 are provided at the connection portion, the minimum distance from the connection portion to the end of the support beam 200 should be understood as the minimum distance between the end of the support beam 200 and the nearest slider 430.

[0041] According to a second aspect of the embodiments of this application, a PCB processing equipment is provided, including a gantry structure and a processing module. The processing module is disposed on a support beam 200 for processing workpieces. The support beam 200 slides relative to a frame 100 along a first direction. In this embodiment, the first direction may be the width direction of the support beam 200.

[0042] In one embodiment, the frame 100 is provided with multiple processing stations 110 for carrying workpieces. Each processing station 110 is equipped with a processing module, which includes at least one processing unit 300 for processing the workpiece. Specifically, one processing unit 300 may be set up on each processing station 110 for processing, or multiple processing units 300 may be set up on the same processing station 110 for simultaneous processing. The PCB processing equipment may be a drilling machine, a forming machine, or a drilling and routing machine, etc.

[0043] In one embodiment, at least one processing station 110 is located outside the drive assembly 400. Specifically, the outside of the drive assembly 400 can be understood as the side of the drive assembly 400 facing the nearest end of the frame 100, and at least one processing station 110 is provided in the area between the drive assembly 400 and the nearest end of the frame 100.

[0044] Specifically, as the connecting part moves inward a certain distance from the end of the support beam 200, the corresponding drive assembly 400 also moves inward a certain distance from the end of the frame 100. Based on the inward movement distance of the drive assembly 400, this inward movement distance is set to be greater than or equal to the length of at least one processing station 110, so as to accommodate at least one processing station 110 in the area between the drive assembly 400 and the end of the frame 100, making full use of the space of the frame 100.

[0045] In one embodiment, the frame 100 further includes a worktable, which is fixedly mounted on the frame 100, and the processing station 110 is mounted on the worktable. This fixed worktable and movable support beam 200 arrangement eliminates the need to reserve space for worktable movement, saving space. Furthermore, the fixed worktable provides more stable support for the PCB, improving processing accuracy.

[0046] In one embodiment, the processing module includes adjacent first processing unit 300 and second processing unit 300; the PCB processing equipment further includes: a first connector and a second connector, wherein the first processing unit 300 of each processing module is connected to the first connector, and the second processing unit 300 of each processing module is connected to the second connector; a first driver and a second driver, wherein the first driver is used to drive the first connector to move along a second direction, and the second driver is used to drive the second connector to move along a second direction, wherein the second direction may be the length direction of the support beam 200, and the second direction is perpendicular to the first direction.

[0047] Specifically, the first processing unit 300 in each processing module is simultaneously connected to the first connecting member, and the second processing unit 300 in each processing module is simultaneously connected to the second connecting member. When the first connecting member is driven by the first driver, the first processing units 300 in each processing module can be driven simultaneously, so that multiple first processing units 300 can be moved simultaneously to the same position of multiple workpieces for processing. When the second connecting member is driven by the second driver, the second processing units 300 in each processing module can be driven simultaneously, so that multiple second processing units 300 can be moved simultaneously to the same position of multiple workpieces for processing. In this way, the consistency of processing multiple workpieces can be improved while saving driving force. Of course, this embodiment is not limited to including only the first processing unit 300 and the second processing unit 300 in the same processing module; it may also include a third processing unit 300 or more processing units 300.

[0048] In another embodiment, each processing unit 300 is equipped with a third driver, which drives the processing unit 300 to move along the second direction. That is, each processing unit 300 moves independently to provide a more flexible driving configuration, enabling multiple processing units 300 to move to different positions on multiple workpieces to process different positions on multiple workpieces simultaneously. Of course, multiple processing units 300 can also move to the same position on multiple workpieces to process the same position on multiple workpieces simultaneously.

[0049] In one embodiment, the processing unit 300 includes a spindle 310 for drilling or forming, and a fourth driver for driving the spindle 310 to move along the height direction, so that the spindle 310 of each processing unit 300 can independently process different workpieces. Alternatively, the processing unit 300 can be moved along the width direction by the support beam 200, thereby moving the spindle 310 to different positions of the workpiece in the width direction for processing. Or, a fifth driver can be provided in each processing unit 300 to drive the spindle 310 to move along the width direction, also allowing the spindle 310 to move to different positions of the workpiece in the width direction for processing.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.

In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
