For those skilled in the art, the specific meaning of the above-mentioned term in the present application can be understood according to the specific circumstances.

[0041] Some embodiments of the present application will be described in detail below with reference to the drawings.

[0042] Please refer to Figure 1This application provides a processing apparatus 200, which includes a processing spindle 201, a processing mechanism 202, and a positioning mechanism 100, for processing a workpiece 300. The workpiece 300 can be a mobile phone frame.

[0043] Please see Figure 1 The processing mechanism 202 is located on one side of the processing spindle 201 and is used to process the workpiece 300. The processing spindle 201 is a machine tool spindle that can move up and down. The first adsorption assembly 10 is connected to the processing spindle 201 and is used to adsorb the cover plate 400. The support assembly 20 is located below the first adsorption assembly 10 and is used to support the workpiece 300. The second adsorption assembly 30 includes a second adsorption element 31 and a driving element 32. The second adsorption element 31 is movably inserted through the support assembly 20 and connected to the driving element 32. The adsorption force of the second adsorption element 31 is greater than the adsorption force of the first adsorption assembly 10. The driving element 32 is used to drive the second adsorption element 31 away from the first adsorption assembly 10 so that the processing spindle 201 drives the first adsorption assembly 10 to move the cover plate 400 away from the workpiece 300. The driving element 32 is also used to drive the second adsorption element 31 closer to the first adsorption assembly 10 so that the second adsorption element 31 adsorbs the cover plate 400 onto the workpiece 300. For example, the driving element 32 can be a cylinder.

[0044] In actual use, the aforementioned positioning mechanism 100 and processing device 200 firstly drive the second adsorption member 31 away from the first adsorption assembly 10 to increase the distance between the second adsorption member 31 and the first adsorption assembly 10. Then, the first adsorption assembly 10 adsorbs the cover plate 400 and moves away from the bearing assembly 20 under the drive of the processing spindle 201, so that the cover plate 400 is detached from the processed workpiece 300. Finally, the workpiece 300 to be processed replaces the processed workpiece 300 and is placed on the bearing assembly 20. The driving member 32 drives the second adsorption member 31 to move closer to the first adsorption assembly 10, and the processing spindle 201 drives the first adsorption assembly 10 to move closer to the bearing assembly 20. Since the adsorption force of the second adsorption member 31 is greater than that of the first adsorption assembly 10, and the distance between the second adsorption member 31 and the first adsorption assembly 10 becomes smaller, the second adsorption member 31 adsorbs the cover plate 400 to the workpiece 300 to position the workpiece 300, which facilitates the processing mechanism 202 to process the positioned workpiece 300, replacing manual handling of the cover plate and improving production efficiency.

[0045] It is understood that the adsorption form of the above-mentioned adsorption cover plate 400 can be vacuum adsorption or magnetic adsorption. In this embodiment, the first adsorption component 10 and the second adsorption component 30 magnetically adsorb the cover plate 400, wherein a magnetic suction element (not shown) is embedded in the cover plate 400. The magnetic properties of the opposite ends of the magnetic suction element are opposite. The end of the magnetic suction element adjacent to the first adsorption component 10 is opposite to the magnetic properties of the first adsorption component 10, and the end of the magnetic suction element adjacent to the bearing component 20 is opposite to the magnetic properties of the second adsorption element 31, so that both the first adsorption component 10 and the second adsorption component 30 can stably magnetically adsorb the cover plate 400, thereby improving the stability of the cover plate 400 in taking it out and putting it in.

[0046] Please see Figure 1 and Figure 3 In some embodiments, the first adsorption assembly 10 includes a connector 11 and at least one first adsorption member 12 connected to the connector 11. The connector 11 is located on one side of the machining spindle 201 and connected to the machining spindle 201. At least one first adsorption member 12 is connected to the connector 11. The first adsorption member 12 is used to adsorb the cover plate 400 and moves closer to or away from the support assembly 20 under the drive of the connector 11.

[0047] Thus, by setting the specific structure of the first adsorption component 10, the processing spindle 201 drives the first adsorption component 12 and the adsorbed cover plate 400 to move synchronously through the connector 11, replacing manual handling of the cover plate 400 and improving production efficiency.

[0048] It is understood that in some embodiments, the first adsorption element 12 can be plate-shaped, and the cover plate 400 has a simple structure and is also flat, allowing the roughly plate-shaped first adsorption element 12 to fully contact the cover plate 400, thereby improving adsorption stability. In other embodiments, the cover plate 400 has a complex structure, and the first adsorption element 12 can also be roughly rod-shaped, with multiple first adsorption elements 12 spaced apart and all connected to the connecting element 11. The multiple first adsorption elements 12 adsorb different positions on the cover plate 400, thereby adapting to the complex structure of the cover plate 400 and ensuring that the first adsorption assembly 10 stably adsorbs the cover plate 400. It should be noted that the above-mentioned "multiple" refers to two or more.

[0049] Please see Figure 1 and Figure 2 In some embodiments, the second adsorption member 31 includes at least one second adsorption body 311 movably disposed through the support assembly 20 and a linkage body 312. One side of the linkage body 312 is connected to the second adsorption member 311, and the other side of the linkage body 312 is connected to the drive member 32. The linkage body 312 is used to drive multiple second adsorption members 311 to move synchronously under the drive of the drive member 32.

[0050] Thus, by setting the specific structure of the second adsorption element 31, the driving element 32 drives the linkage body 312 to move the second adsorption element 311 synchronously, so as to stably adjust the distance between the second adsorption element 311 and the first adsorption element 12, and ensure that the cover plate 400 can be picked up and placed in the field.

[0051] It is understood that the second adsorption element 311 can be plate-shaped or rod-shaped. When the second adsorption element 311 is roughly rod-shaped, there are multiple second adsorption elements 311. Multiple second adsorption elements 311 are spaced apart on the side of the linkage 312 away from the driving element 32 and are used to adsorb different positions of the cover plate 400 respectively, so as to increase the adsorption area between the second adsorption element 31 and the cover plate 400, which is conducive to the second adsorption element 31 adsorbing the cover plate 400 to the workpiece 300 stably.

[0052] Please see Figure 2 In some embodiments, the second adsorption member 311 includes a movable part 3111 and an adsorption part 3112. One end of the movable part 3111 is movably inserted through the support assembly 20 and connected to the linkage 312, while the other end of the movable part 3111 is detachably connected to the adsorption part 3112. The movable part 3111 is used to drive the adsorption part 3112 to move closer to or away from the first adsorption assembly 10. Exemplarily, the adsorption part 3112 can be any adsorption block, adsorption sheet, or similar adsorption plate capable of adsorbing the cover plate 400, such as a magnet, suction cup, etc.

[0053] Thus, by setting the movable part 3111 and the adsorption part 3112 to be detachably connected, the adsorption part 3112 and the movable part 3111 form a split structure, which makes it easy to replace the adsorption part 3112 in a timely manner according to the usage requirements, avoids replacing the entire structure of the second adsorption part 311, and reduces the cost of use.

[0054] Please see Figure 3 In some embodiments, the first adsorption member 12 includes a limiting body 121, a first adsorption body 122, and an elastic body 123. One end of the limiting body 121 is movably inserted through the connecting member 11, and the other end of the limiting body 121 abuts against the connecting member 11. The first adsorption body 122 is connected to the limiting body 121 and is used to adsorb the cover plate 400. The elastic body 123 is sleeved on the limiting body 121, and its two ends elastically abut against the connecting member 11 and the first adsorption body 122, respectively. Exemplarily, the first adsorption body 122 can be any adsorption block, adsorption sheet, or similar adsorption plate capable of adsorbing the cover plate 400, such as a magnet, suction cup, etc., and the elastic body 123 can be a spring.

[0055] Thus, by setting the specific structure of the first adsorption member 12, when the connector 11 drives the first adsorption member 12 to move closer to the cover plate 400, the connector 11 compresses the elastic body 123 to the first adsorption body 122, so that the first adsorption body 122 flexibly abuts against the cover plate 400, avoiding the first adsorption body 122 and the cover plate 400 from colliding with each other, which is conducive to the first adsorption body 122 stably adsorbing the cover plate 400.

[0056] Please see Figure 1 In some embodiments, the number of first adsorption components 10 and second adsorption components 30 are both multiple sets. Multiple sets of first adsorption components 10 are spaced apart on the processing spindle 201, and multiple sets of second adsorption components 30 correspond one-to-one with the multiple sets of first adsorption components 10 and are spaced apart on the support component 20. It can be understood that the above-mentioned multiple sets refer to two or more sets.

[0057] In this way, by setting up multiple sets of first adsorption components 10 and multiple sets of second adsorption components 30 and making them correspond one-to-one, the positioning mechanism 100 can simultaneously perform positioning operations on multiple workpieces 300, thereby improving production efficiency.

[0058] Please continue reading. Figure 1 In some embodiments, the carrier component 20 includes a substrate 21, a support member 22, a fixing member 23, and a carrier member 24. The substrate 21 is disposed below the first adsorption component 10. One end of the support member 22 is connected to the side of the substrate 21 away from the first adsorption component 10. The fixing member 23 is connected to the other end of the support member 22 and is connected to the driving member 32. The fixing member 23 and the substrate 21 form an active space 231 for accommodating the driving member 32. The carrier member 24 is disposed on the side of the substrate 21 away from the support member 22. The second adsorption member 31 is movably inserted through the substrate 21 and the carrier member 24. The carrier member 24 is used to carry the workpiece 300.

[0059] Thus, by setting the specific structure of the above-mentioned support component 20, an active space 231 is formed between the fixing member 23 and the substrate 21, so that the active space 231 can accommodate the driving member 32 and the linkage body 312, so that the support component 20 and the second adsorption component 30 are reasonably arranged.

[0060] Please see Figure 1 In some embodiments, a positioning body 241 is provided on the side of the carrier 24 facing away from the substrate 21. The positioning body 241 is adapted to the workpiece 300 and is used to position the workpiece 300. It can be understood that the positioning body 241 can be a protrusion, a plane, a groove, etc.

[0061] Thus, by setting the positioning body 241 to be compatible with the workpiece 300, the positioning body 241 positions the workpiece 300 so that the workpiece 300 maintains a preset orientation and placement position on the carrier 24, which is beneficial for the processing mechanism 202 to stably process the workpiece 300.

[0062] Please see Figure 1 In some embodiments, the positioning mechanism 100 further includes a transfer member 40 connected to the support assembly 20. The transfer member 40 is used to drive the support assembly 20 to move the workpiece 300 relative to the machining spindle 201. Exemplarily, the transfer member 40 can be any transfer carrier, transfer part, or similar transfer block capable of driving the support assembly 20 to move, such as a cylinder.

[0063] Thus, by setting the aforementioned transfer member 40, the transfer member 40 drives the bearing assembly 20 and the positioned workpiece 300 to move relative to the machining spindle 201, so that the machining mechanism 202 corresponds to the workpiece 300 carried by the bearing assembly 20, which facilitates the machining mechanism 202 to stably process the workpiece 300.

[0064] The working process of the aforementioned processing device 200 is roughly as follows:

[0065] First, the carrier 24 carries the workpiece 300, and the second adsorption member 31 adsorbs the cover plate 400 to the workpiece 300 to position the workpiece 300. The transfer member 40 drives the carrier 24 and the workpiece 300 to be processed to move relative to the processing spindle 201 so that the processing mechanism 202 corresponds to the workpiece 300 carried by the carrier 24, and the processing mechanism 202 processes the workpiece 300.

[0066] Then, the transfer member 40 drives the carrier member 24 and the processed workpiece 300 to move away from the processing mechanism 202, and the driving member 32 drives the second adsorption member 31 to move away from the first adsorption member 12, so as to increase the distance between the first adsorption member 12 and the second adsorption member 31, and reduce the adsorption force applied by the second adsorption member 31 to the cover plate 400.

[0067] Next, the first adsorption element 12 adsorbs the cover plate 400 and moves away from the bearing element 24 under the drive of the machining spindle 201, so that the cover plate 400 is detached from the machined workpiece 300.

[0068] Finally, the workpiece 300 to be processed replaces the processed workpiece 300 and is placed on the support member 24. The driving member 32 drives the second adsorption member 31 to move closer to the first adsorption member 12. The processing spindle 201 drives the first adsorption member 12 to move closer to the support member 24. Since the adsorption force of the second adsorption member 31 is greater than the adsorption force of the first adsorption component 10, and the distance between the second adsorption member 31 and the first adsorption member 12 becomes smaller, the second adsorption member 31 adsorbs the cover plate 400 to the workpiece 300 to position the workpiece 300, which facilitates the processing mechanism 202 to repeatedly process the positioned workpiece 300 and improve production efficiency.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
