[0041] The invention discloses a positioning module to improve the positioning accuracy of the positioning module and improve the product yield.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figure 1-Figure 5 , Figure 1 A schematic diagram of the structure of a positioning module provided by an embodiment of the present invention; Figure 2 A front view of a positioning module provided by an embodiment of the present invention; Figure 3 A top view of a positioning module provided by an embodiment of the present invention; Figure 4 A top view of the movable plate installation of the positioning module provided by an embodiment of the present invention; Figure 5 A top view of the base plate installation of the positioning module provided in an embodiment of the present invention.

[0044] The present invention discloses a positioning module, which comprises a bottom plate 100, a top plate 300, a movable plate 200, a linear driving device and a first sliding component.

[0045] The top plate 300 , the movable plate 200 , the linear drive device and the first sliding assembly are all installed on the bottom plate 100 .

[0046] The top plate 300 is used to position the product, and a fixed position for placing the product is provided on the top plate 300 .

[0047] The top plate 300 is installed on the bottom plate 100 through the movable plate 200. The movable plate 200 moves, driving the top plate 300 to move, thereby achieving position adjustment of the product placed on the top plate 300.

[0048] The linear drive device is installed on the bottom plate 100 , and can drive the movable plate 200 to perform linear motion along the driving direction of the linear drive device, thereby adjusting the position of the product along the driving direction of the linear drive device.

[0049] The first sliding assembly is installed on the linear driving device, which drives the movable plate 200 to move. The first sliding assembly also moves along the driving direction of the linear driving device along with the movable plate 200. The sliding direction of the first sliding assembly is perpendicular to the driving direction of the linear driving device. That is to say, the first sliding assembly can not only move along with the linear driving device, but also has its own sliding direction.

[0050] Specifically, the linear driving device drives the movable plate 200 to move, the movable plate 200 moves along the driving direction of the linear driving device, and the movable plate 200 moves along the first sliding assembly of the linear driving device adjacent thereto.

[0051] The first sliding assembly is rotatably connected to the movable plate 200 . The rotatable connection can reduce the friction between the first sliding assembly and the movable plate 200 , thereby protecting the movable plate 200 and extending the service life of the positioning module to a certain extent.

[0052] In this solution, there are at least two linear drive devices, and the driving directions of adjacent linear drive devices are perpendicular. Here, the driving direction of one of the linear drive devices is named as X, and correspondingly, the driving direction of the adjacent linear drive device is named as Y. Then, the sliding direction of the first sliding assembly connected to the linear drive device with the driving direction X is Y, and the sliding direction of the first sliding assembly connected to the linear drive device with the driving direction Y is X. When the linear drive device with the driving direction X pushes the movable plate 200 to move, the linear drive device with the driving direction Y does not work, and the movable plate 200 pushes the first sliding assembly of the linear drive device with the driving direction Y to slide along the X direction; when the linear drive device with the driving direction Y pushes the movable plate 200 to move, the linear drive device with the driving direction X does not work, and the movable plate 200 pushes the first sliding assembly of the linear drive device with the driving direction X to slide along the Y direction. It should be noted here that there are multiple linear drive devices. When one of the linear drive devices with a driving direction of X is working, all the linear drive devices with a driving direction of X are working and have the same driving direction. When one of the linear drive devices with a driving direction of Y is working, all the linear drive devices with a driving direction of Y are working and have the same driving direction.

[0053] The positioning module provided by this solution can realize the position adjustment of the product in the X direction and the Y direction. It can realize the position adjustment of the product in a single direction along the X direction or the Y direction, and can also realize the position adjustment in both directions of the X direction and the Y direction, thereby ensuring the positioning accuracy of the product. The positioning accuracy can reach 0.005mm. The excellent quality accuracy of the printed product reaches 0.05mm, which improves the product yield and has great economic and practical value.

[0054] In order to further optimize the above technical solution, the positioning module provided in this solution also includes a second sliding component, and the second sliding component includes a transmission block 105 and a cross slide block 107 .

[0055] One end of the transmission block 105 is connected to the linear drive device, and the other end is connected to the cross slider 107 . The length extension direction of the transmission block 105 is perpendicular to the driving direction of the linear drive device.

[0056] The cross slider 107 is installed on the bottom plate 100 through the first linear guide rail 106 , and the transmission block 105 can slide along the first linear guide rail 106 , thereby reducing the resistance of driving the transmission block 105 to move.

[0057] In the first specific embodiment of the present scheme, the linear drive device includes a motor 101 and a lead screw 104 .

[0058] Among them, one end of the screw 104 is connected to the motor 101 through the coupling 102, and the other end of the screw 104 is connected to the first sliding component. Specifically, the transmission block 105 is threadedly connected to the screw 104, and when the screw 104 rotates, the transmission block 105 moves horizontally along the axis of the screw 104.

[0059] The motor 101 provides power for the screw 104 to rotate. When the screw 104 rotates, the first sliding assembly moves linearly along the axis of the screw 104, thereby driving the movable plate 200 to move. The high adjustment accuracy of the screw can make the positioning accuracy of the positioning module reach 0.005mm.

[0060] It should be noted here that in order to achieve the consistency between the movement direction of the transmission block 105 and the axial direction of the screw 104, the first linear guide 106 is arranged parallel to the screw 104, and the first sliding component is installed on the cross slider 107, and the sliding direction of the first sliding component is perpendicular to the first linear guide 106.

[0061] In order to further optimize the first specific embodiment, the positioning module provided in this solution also includes a fixing block 103 installed on the base plate 100 for supporting the lead screw 104 . The fixing block 103 supports the lead screw 104 to ensure stable transmission of the lead screw 104 .

[0062] In the second specific embodiment of the present solution, the linear driving device is a cylinder, the piston rod of the cylinder is connected to the first sliding assembly, and the movable plate 200 is driven to move by the extension and retraction of the cylinder piston rod.

[0063] One end of the transmission block 105 is connected to the piston rod of the cylinder, and the other end is connected to the cross slide block 107. The length extension direction of the transmission block 105 is perpendicular to the axial direction of the piston rod of the cylinder.

[0064] The transmission block 105 is fixedly connected to the piston rod of the cylinder. When the piston rod of the cylinder is extended or retracted, the transmission block 105 moves in translation along the axis of the piston rod of the cylinder.

[0065] It should be noted here that in order to achieve consistency between the movement direction of the transmission block 105 and the axial direction of the cylinder's piston rod, the first linear guide 106 is arranged parallel to the cylinder's piston rod, and the first sliding assembly is installed on the cross slider 107, and the sliding direction of the first sliding assembly is perpendicular to the first linear guide 106.

[0066] In order to further optimize the above technical solution, the positioning module provided in the first embodiment and the second embodiment further includes: a plug 111 and a photoelectric coupler 112. The plug 111 is connected to the transmission block 105, and the photoelectric coupler 112 is installed on the bottom plate, and the photoelectric coupler 112 is perpendicular to the transmission block 105.

[0067] The inserting piece 111 cooperates with the photoelectric coupler 112 to detect the position of the movable plate 200, thereby further improving the position adjustment accuracy of the product.

[0068] In a specific embodiment of this solution, the first sliding assembly includes:

[0069] A second linear guide rail 108 connected to the cross slide 107, wherein the second linear guide rail 108 is perpendicular to the first linear guide rail 106;

[0070] The fixed block 109 is mounted on the second linear guide 108, and the fixed block 109 is rotatably connected to the movable plate 200. The first linear guide 106 is located at the lower end surface of the cross slide 107, and the second linear guide 108 is located at the upper end surface of the cross slide 107. The cross slide 107 can slide along the first linear guide 106, and the cross slide 107 is fixedly connected to the second linear guide 108, and the fixed block 109 can slide along the second linear guide 108.

[0071] The rotation connection between the movable plate 200 and the fixed block 109 is as follows:

[0072] The fixed block 109 is provided with a column arranged perpendicularly to the second linear guide rail 108, and a bearing 220 is sleeved on the column, and the inner ring of the bearing 220 cooperates with the column;

[0073] The movable plate 200 is provided with a mounting hole that matches with the outer ring of the bearing 220 .

[0074] The fixing block 109 serves to connect the second linear guide rail and the bearing 220 .

[0075] The bearing 220 can cooperate with the first sliding assembly, the second sliding assembly and the linear drive device to prevent jamming when they work simultaneously and to achieve micro-motion when they move simultaneously, thereby realizing flexible linkage of multiple axes.

[0076] The rotating connection method can reduce the damage to the movable plate 200 and the fixed block 109, and to a certain extent prolong the service life of the positioning module.

Alternatively, linear drive devices are arranged at two right angles of the bottom plate, and the driving directions of the two linear drive devices are opposite. The first sliding assembly and the second sliding assembly are arranged at the other two right angles of the bottom plate. The above two right angles can be adjacent right angles or diagonal right angles.
