[0053] The use of cross-hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.
[0054] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present.

Figure 2 is a schematic structural diagram of a workpiece positioning system 100 according to an embodiment of the present disclosure. Figure 3 2 is a schematic structural diagram of a workpiece positioning system 100 according to an embodiment of the present disclosure from another angle.
[0058] like Figure 1 As shown, when the workpiece positioning system 100 of the present invention is used, its mounting plate 110 can be mounted on the end of a mechanical arm, and accordingly, the positioned workpiece can be transported to a preset position by the mechanical arm, where the workpiece can be mounted on other parts. In a preferred embodiment, the workpiece can be a reading head, and the positioning and transport of the reading head can be achieved by the workpiece positioning system 100 of the present invention.
[0059] like Figure 2 and Figure 3 As shown, in the present disclosure, the workpiece positioning system 100 includes: a mounting plate 110, a base plate 120, a clamping device 130, a clamping device 140, a positioning device 150 and other components.
[0060] The base plate 120 is floatingly arranged on the mounting plate 110. In a specific embodiment, the mounting plate 110 is provided with guide rods and other components. Preferably, the number of the guide rods is four, and the four guide rods are arranged in parallel, so that the base plate 120 is provided with guide holes, and the guide rods are slidably arranged in the guide holes, so that the base plate 120 can approach or move away from the mounting plate 110 in the vertical direction. In particular, a spring can be arranged between the mounting plate 110 and the base plate 120, so that the base plate 120 can float relative to the mounting plate 110, and accordingly, flexible installation of the workpiece can be achieved.
[0061] The clamping device 130 is disposed on the substrate 120 , wherein the clamping device 130 is used to clamp a workpiece.
[0062] In one embodiment, the clamping device 130 can be implemented by a clamping finger cylinder. Specifically, the clamping device 130 includes a clamping drive device 131, a first clamping component 132 and a second clamping component 133, wherein the first clamping component 132 and the second clamping component 133 are arranged on the clamping drive device 131 and driven by the clamping drive device 131 to produce a work of approaching or moving away from each other; wherein, when the first clamping component 132 and the second clamping component 133 approach each other along a first direction, the workpiece is clamped; when the first clamping component 132 and the second clamping component 133 move away from each other along the first direction, the workpiece is released.
[0063] In the present disclosure, the first direction is a horizontal direction, for example, the first direction may be an X direction. The clamping drive device 131 may be a cylinder.
[0064] The first clamping member 132 and / or the second clamping member 133 include a step portion, the step portion includes a bearing surface, and the workpiece is supported by the bearing surface of the step portion; at the same time, the first clamping member 132 and the second clamping member 133 also position the workpiece from the first direction.
[0065] Specifically, the workpiece is a circuit board, and the circuit board has a substantially fan-shaped shape, and the first clamping member 132 and the second clamping member 133 can position the workpiece from the direction of the chord of the fan-shaped shape. For example, the side wall of the step portion can be formed into a non-planar structure, that is, a structure adapted to the workpiece, thereby improving the positioning efficiency and accuracy of the workpiece.
[0066] The pressing device 140 is disposed on the substrate 120 . In the present disclosure, the pressing device 140 can be directly disposed on the substrate 120 or indirectly disposed on the substrate 120 . The pressing device 140 is used to press the workpiece clamped by the clamping device 130 .
[0067] In a specific embodiment, the pressing device 140 includes: a base 141 , a guide member 142 , a driving member 143 and a pressing block 144 .
[0068] The base 141 can be directly disposed on the substrate 120; and the pressing device 140 can be directly disposed on the substrate 120. Figure 2 and Figure 3 As shown, the base 141 can be disposed on the clamping drive device 131 , so that the pressing device 140 is indirectly disposed on the substrate 120 .
[0069] The guide member 142 is slidably disposed on the base plate 120. Specifically, the base plate 120 has a protrusion 1411, and the protrusion 1411 is provided with two guide holes, and the guide member 142 is slidably disposed in the guide holes. More preferably, the guide members 142 of the present disclosure are all vertically disposed, and accordingly, the guide members 142 can move in the vertical direction.
[0070] More preferably, a bushing or a linear bearing or other components may be provided in the guide hole on the protrusion 1411 , so that when the guide member 142 slides relative to the base 141 , there is less friction resistance.
[0071] Therefore, the movement direction of the guide member 142 of the present disclosure is a direction approaching or moving away from the workpiece along the second direction; wherein the second direction may be a vertical direction, namely, the Z direction.
[0072] The driving member 143 is disposed on the base 141 and connected to one end of the guide member 142; thus, the guide member 142 can be moved up and down by the driving member 143. Preferably, the driving member 143 can be a cylinder, the cylinder body of the cylinder can be fixed to the clamping drive device 131, and the piston rod of the cylinder is fixedly connected to the connecting plate 145. At this time, the connecting plate 145 is connected to the upper end of the guide member 142.
[0073] In the present disclosure, a limiting component 146 is disposed on the connecting plate 145 , and the downward movement position of the pressing block 144 is limited by the contact between the limiting component 146 and the base 141 (eg, the protrusion of the base 141 ).
[0074] The pressing block 144 is disposed at the other end (ie, the lower end) of the guide member 142 , and the workpiece is pressed by the pressure contact between the pressing block 144 and the workpiece.
[0075] In other words, when the pressing device 140 presses the workpiece, the workpiece is located between the pressing device 140 and the bearing surface.
[0076] In the present disclosure, the positioning device 150 is disposed on the substrate 120 to position the workpiece.
[0077] In a specific embodiment, the positioning device 150 includes: a positioning drive device 151 , a fixing plate 152 , a connecting portion 153 and an inserting piece 154 .
[0078] The positioning drive device 151 is arranged on the substrate 120. In the present disclosure, the positioning drive device 151 can be a cylinder; the fixed plate 152 is slidably arranged on the substrate 120 along a third direction. Specifically, a slider is arranged on the lower surface of the substrate 120, and a guide rail is arranged on the fixed plate 152. The guide rail is slidably arranged in the slider, and the positioning drive device 151 is used to drive the fixed plate 152 to slide relative to the substrate 120.
[0079] The plug 154 is connected to the fixing plate 152 via the connecting portion 153, and the position of the plug 154 can be adjusted in a first direction and a second direction relative to the fixing plate 152. Therefore, when the plug 154 of the present disclosure is installed on the fixing plate 152, the plug 154 can be adjusted to a preset position, and then the plug 154 can be fixed to the fixing plate 152. In the present disclosure, the position adjustment of the plug 154 can be achieved by providing a long strip groove on the fixing plate 152 and the connecting portion 153. This structure is already a prior art in the art, and the present disclosure will not be repeated here.
[0080] The insert 154 is configured to approach or move away from the workpiece along a third direction, and enables the insert 154 to be inserted into a gap between the workpiece and parts near the workpiece. Thus, when the workpiece positioning system of the present invention is in use, the insert 154 can ensure a gap between the reader and the part on which the reader is installed (or parts near the reader), thereby ensuring that the installation process meets the requirements.
[0081] The workpiece positioning system disclosed in the present invention can realize the positioning and clamping of the workpiece at multiple angles, solving the technical problems of the structure of the reader, special materials, high installation requirements, etc. At the same time, the positioning and automatic transportation of the workpiece can be realized through the workpiece positioning system disclosed in the present invention, which also solves the technical problem of high working intensity of manual devices.
[0082] When the workpiece positioning system disclosed in the present invention is in use, the robot arm drives the workpiece positioning system to the position of the head reader product. First, the clamping device clamps the head reader, and then the pressing device presses the head reader clamped by the clamping device. The robot arm drives the device to move to the head reader installation position, and the insert of the positioning device is pushed out to ensure that the head reader is installed in the correct position. After tightening the screws, the insert of the positioning device retracts, the pressure block of the pressing device rises, and the clamping device releases the head reader. The robot drives the device back to the position of the head reader product and repeats the installation of the next head reader product.
