For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that allows communication between the two; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two elements or the interaction between two elements. In the description of this application, it should be noted that "multiple" means two or more, unless otherwise expressly and specifically limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0042] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0043] Please see Figure 1 This application provides a transfer mechanism 100, including a lower mold support assembly 110, an attitude detection assembly 120, a conveying assembly 130, and a transfer assembly 140. The transfer mechanism 100 is used to transfer workpieces onto the lower mold to improve the transfer efficiency of the workpieces and to achieve a miniaturized design of the transfer mechanism 100. For example, the workpiece can be glass.

[0044] Please see Figure 1 and Figure 2 The lower mold support assembly 110 is used to support the lower mold. The attitude detection assembly 120 includes an attitude detection camera 121 and an attitude detection light source 122, which are disposed opposite to each other on the upper and lower sides of the lower mold support assembly 110. The conveying assembly 130 is disposed on one side of the lower mold support assembly 110. The transfer assembly 140 includes a first drive unit 141, a rotation drive component 142, and a transfer suction unit 143. One end of the first drive unit 141 is connected to the conveying assembly 130 and is used to transfer material from the conveying assembly 130 to the lower mold. Driven by the first drive unit 141, the transfer assembly 140 is moved closer to or away from the lower mold support assembly 110. The other end of the first drive unit 141 is connected to the transfer suction unit 143, which is used to drive the transfer suction unit 143 to move so that the transfer suction unit 143 moves closer to or away from the lower mold support assembly 110. The rotating drive unit 142 drives the transfer suction unit 143 to adjust the posture of the workpiece picked up by the transfer suction unit 143. The transfer suction unit 143 is used to place the workpiece on the lower mold when it reaches the first set position above the lower mold support assembly 110.

[0045] It should be noted that the first set position is set in the Z-axis direction corresponding to the lower mold support component 110, that is, the first set position is a position point of the lower mold support component 110 in the Z-axis direction.

[0046] In the aforementioned transfer mechanism 100, the transfer component 140 can cooperate with the conveying component 130 and the attitude detection component 120 to respectively complete the transfer of the workpiece and the adjustment of its attitude, which can simplify the workpiece transfer process and improve the workpiece transfer efficiency. In addition, the above-mentioned configuration can optimize the layout of the transfer mechanism 100, thereby achieving a miniaturized configuration of the transfer mechanism 100.

[0047] For ease of description, in Figure 1 and Figure 3 A three-dimensional coordinate system has been added to all components. Specifically, the X-axis is the moving direction of the first driving unit 141, the Y-axis is the rotation axis direction of the rotation driving component 142, and the Z-axis is the lifting direction of the translation driving component 1411. The X-axis, Y-axis, and Z-axis are perpendicular to each other.

[0048] Please see Figure 2 In this embodiment, the lower mold support assembly 110 includes a lower mold bracket 111, a lower mold drive 112, and a lower mold support seat 113. The lower mold bracket 111 extends along the Y-axis direction, and the lower mold support seat 113 is slidably disposed on the lower mold bracket 111 along the Y-axis direction to support the workpiece. The lower mold support seat 113 has a hollow structure. The lower mold drive 112 is disposed on the lower mold bracket 111 and connected to the lower mold support seat 113 to drive the lower mold support seat 113 to move along the Y-axis direction.

[0049] In this embodiment, the attitude detection light source 122 is disposed within the lower mold support 111 and located on the side of the lower mold support 113 opposite to the attitude detection camera 121. When the workpiece picked up by the transfer suction unit 143 reaches the first set position above the lower mold support assembly 110, the attitude detection light source 122 and the attitude detection camera 121 are activated synchronously. The light emitted by the attitude detection light source 122 illuminates the workpiece, so that the attitude detection camera 121 can obtain a clear outline of the workpiece, which helps to improve the accuracy of workpiece attitude adjustment. For example, the attitude detection light source 122 can be a surface light source, and the lower mold drive 112 can be a servo motor.

[0050] Please see Figure 3 In some embodiments, the first drive unit 141 includes a translation drive 1411 and a lifting drive 1412. The translation drive 1411 drives the transfer and suction unit 143 to move the transfer and suction unit 143 closer to or further away from the conveying assembly 130 along the Y-axis direction, and the lifting drive 1412 drives the transfer and suction unit 143 to move the transfer and suction unit 143 closer to or further away from the lower mold support assembly 110 along the Z-axis direction.

[0051] In some embodiments, the fixed end of the lifting drive 1412 is connected to the conveying assembly 130, the fixed end of the translation drive 1411 is connected to the drive end of the lifting drive 1412, so that the translation drive 1411 moves up and down along the Z-axis under the drive of the lifting drive 1412, the fixed end of the rotation drive 142 is connected to the drive end of the translation drive 1411, so that the rotation drive 142 moves along the Y-axis under the drive of the translation drive 1411, and the drive end of the rotation drive 142 is connected to the transfer and suction unit 143, so that the rotation drive 142 drives the transfer and suction unit 143 to rotate. Exemplarily, both the translation drive 1411 and the lifting drive 1412 can be servo motors or telescopic cylinders.

[0052] Please see Figure 3 and Figure 4 In some embodiments, the transfer suction unit 143 includes a transfer suction component 1431 and a linkage component 1432. The transfer suction component 1431 includes a connecting body 1431a, a fixing body 1431b, and a transfer suction head 1431c. The connecting body 1431a is connected to the transfer suction head 1431c through the fixing body 1431b. The rotation drive component 142 drives the linkage component 1432, and the linkage component 1432 is slidably connected to the connecting body 1431a along the Z-axis direction.

[0053] Therefore, the linkage 1432 slides along the Z-axis to connect the connecting body 1431a, which allows the transfer suction head 1431c with the workpiece adsorbed to slide relative to the linkage 1432, so as to avoid hard collision between the transfer suction head 1431c and the workpiece, thereby improving the service life of the transfer suction head 1431c.

[0054] Please see Figure 4 In some embodiments, the transfer and suction unit 143 further includes a limiting member 1433. A limiting groove 1431d is formed on the outer side of the connecting body 1431a. The limiting member 1433 is connected to the linkage member 1432 and extends into the limiting groove 1431d. The limiting member 1433 extending into the limiting groove 1431d can move within the limiting groove 1431d along the Z-axis direction.

[0055] Therefore, by using the limiting member 1433 in conjunction with the limiting groove 1431d, the range of motion of the linkage member 1432 along the Z-axis can be limited, thereby improving the floating accuracy of the transfer suction head 1431c.

[0056] In some embodiments, the transfer and suction unit 143 further includes a pressure sensor 1434. The pressure sensor 1434 is disposed on the side of the fixed body 1431b facing the linkage 1432 and is electrically connected to the lifting drive 1412. The pressure sensor 1434 measures the magnitude of the force generated between the fixed body 1431b and the linkage 1432 and transmits the measured force to the lifting drive 1412, so that the lifting drive 1412 adjusts the force exerted by the transfer and suction unit 143 on the workpiece. The working principle and process of the pressure sensor 1434 cooperating with the lifting drive 1412 to adjust the force exerted by the transfer and suction unit 143 on the workpiece can be directly obtained from published literature and will not be elaborated here.

[0057] In some embodiments, the transfer suction unit 143 further includes an elastic element 1435. The two ends of the elastic element 1435 abut against the fixed body 1431b and the linkage member 1432, respectively. When the transfer suction head 1431c abuts against the workpiece to achieve adsorption of the workpiece, the workpiece generates a reaction force on the fixed body 1431b through the transfer suction head 1431c, causing the fixed body 1431b to compress the elastic element 1435. When the transfer suction unit 143 moves the adsorbed workpiece, the elastic force of the elastic element 1435 is released. The released elastic force pushes the fixed body 1431b to move the transfer suction head 1431c away from the linkage member 1432, thereby resetting the transfer suction head 1431c. Exemplarily, the elastic element 1435 can be a spring.

[0058] Please see Figure 3 In some embodiments, the transfer mechanism 100 further includes a workpiece carrying assembly 150 and a flipping assembly 160. The workpiece carrying assembly 150 is located on one side of the conveying assembly 130 in the Y-axis direction and is used to carry the workpiece. The flipping assembly 160 includes a second driving unit 161, a flipping driving member 162, and a flipping suction unit 163. One end of the second driving unit 161 is connected to the conveying assembly 130 and is used to move the flipping assembly 160 closer to or further away from the workpiece carrying assembly 150 in the X-axis direction under the drive of the conveying assembly 130. The other end of the second driving unit 161 is connected to the flipping suction unit 163 and is used to drive the flipping suction unit 163 closer to or further away from the workpiece carrying assembly 150 in the Z-axis direction. The flipping driving member 162 drives the flipping suction unit 163 and is used to adjust the orientation of the workpiece picked up by the flipping suction unit 163. The flipping suction unit 163 is used to pick up the workpiece when it reaches a second set position above the workpiece carrying assembly 150 and release the workpiece when it reaches a third set position close to the transfer assembly 140.

[0059] It should be noted that the second setting position is set in the Z-axis direction corresponding to the workpiece bearing assembly 150, and the first setting position, the third setting position, and the second setting position are set sequentially along the X-axis direction.

[0060] In some embodiments, the fixed end of the second drive unit 161 is connected to the conveying assembly 130, the drive end of the second drive unit 161 is connected to the fixed end of the flip drive member 162, and the drive end of the flip drive member 162 is connected to the flip suction unit 163.

[0061] In this embodiment, the flipping suction unit 163 includes a flipping mounting member 1631 and a plurality of flipping suction heads 1632. The flipping mounting member 1631 is connected to the driving end of the flipping drive member 162, and the plurality of flipping suction heads 1632 are respectively connected to the flipping mounting member 1631 and located on the same side of the flipping mounting member 1631.

[0062] Please see Figure 3 In this embodiment, the second drive unit 161 conveying assembly 130 includes a conveying bracket 131, a first conveying drive member 132, and a second conveying drive member 133. The conveying bracket 131 extends along the X-axis direction. The first conveying drive member 132 is disposed on the conveying bracket 131 and connected to the lifting drive member 1412 of the first drive unit 141, and is used to drive the lifting drive member 1412 to move along the X-axis direction, so that the transfer assembly 140 moves along the X-axis direction. The second conveying drive member 133 is disposed on the conveying bracket 131 and connected to the second drive unit 161, and is used to drive the second drive unit 161 to move along the X-axis direction, so that the flipping assembly 160 moves along the X-axis direction. Exemplarily, both the first conveying drive member 132 and the second conveying drive member 133 can be servo motors.

[0063] Please see Figure 1 In some embodiments, the transfer mechanism 100 further includes an appearance inspection camera 170, which is set at a third predetermined position for photographing the appearance of the workpiece. The transfer assembly 140 also includes an appearance inspection light source 144, which is set on the fixing body 1431b of the transfer suction unit 143 facing the appearance inspection camera 170.

[0064] When the flipping component 160 moves the workpiece to the third preset position, the transfer and suction unit 143 picks up the workpiece, and the appearance inspection camera 170 and the appearance inspection light source 144 are activated simultaneously to inspect the appearance of the workpiece. The light emitted by the appearance inspection light source 144 illuminates the surface of the workpiece, creating a light difference between the workpiece surface and its surroundings, which helps the appearance inspection camera 170 obtain a clear image of the workpiece's appearance.

[0065] Please see Figure 1This application also provides an assembly apparatus 200, including a workpiece loading mechanism 210, a lower mold loading mechanism (not shown), and a transfer mechanism 100 as described in the above embodiments. The workpiece loading mechanism 210 is used to provide workpieces, and the lower mold loading mechanism is used to transport the lower mold to the lower mold support assembly 110. Exemplarily, the lower mold loading mechanism can be a lower mold robot, used to drive the lower mold onto the lower mold support seat 113 of the lower mold support assembly 110.

[0066] In this embodiment, the workpiece loading mechanism 210 includes a workpiece loading rack 211 and a workpiece loading drive 212, i.e., a workpiece feeding unit (not shown).

The workpiece feeding unit is disposed on the side of the workpiece loading rack 211 away from the conveying assembly 130, and is used to provide workpieces to the workpiece bearing assembly 150.

[0068] In the transfer mechanism 100 of the assembly device 200, the transfer component 140 can cooperate with the conveying component 130 and the attitude detection component 120 to respectively complete the transfer of the workpiece and the adjustment of its attitude. This simplifies the workpiece transfer process and improves the workpiece transfer efficiency of the assembly device 200. In addition, the above arrangement can optimize the layout of the transfer mechanism 100, which is conducive to the miniaturization of the assembly device 200.
