Description

Technical Field

[0001] The present application relates to the field of automatic feeding, and in particular to an anti-adhesion feeding device and a back cover feeding machine. Background Art

[0002] In modern manufacturing, automated loading equipment is a crucial tool for improving production efficiency and product quality. This is particularly true in the electronics sector, where many materials are thin sheets, such as mobile phone back covers. However, these thin sheets often stick together during automated loading, a major obstacle to production efficiency and product quality.

[0003] Due to their physical properties, such as smooth surfaces and thin thickness, thin sheets are prone to static electricity or vacuum adsorption when stacked and stored, causing multiple sheets to stick together during unloading. This adhesion not only leads to equipment malfunctions but can also cause production line halts, increasing production costs and time.

[0004] Traditional loading devices often lack effective sticking detection and handling mechanisms, often relying on manual intervention to resolve sticking issues. This approach is not only inefficient but also prone to human error, impacting production continuity and stability. Utility Model Content

Moreover, the specific features, structures, materials, or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.

[0039] In a first aspect, the present application provides an anti-adhesion feeding device. Figure 1 and Figure 4 This is a structural diagram of the anti-adhesion feeding device of the embodiment of the present application, which includes a frame, a transfer mechanism 200, a suction assembly 300 and a storage frame 100. The frame provides an installation base for each component of the device. Figure 4 As shown, the material storage frame 100 is stacked with material plates 1000, and a scraping mechanism 400 is provided on the top of the material storage frame 100. The scraping mechanism 400 is used to separate the material plates 1000 that are stuck together. Figure 1As shown, the transfer mechanism 200 includes a transverse module 210 and a lifting drive member 220, wherein the lifting drive member 220 is arranged on the driving end of the transverse module 210, and the transverse module 210 can drive the lifting drive member 220 to move transversely along the first path; the driving end of the lifting drive member 220 is provided with a connecting tongue 221, and the driving end of the lifting drive member 220 can drive the connecting tongue 221 to move up and down; the suction component 300 is arranged on the connecting tongue 221, thereby realizing the transverse movement and the vertical movement of the suction component 300. Figure 2 and Figure 3 As shown, the material suction assembly 300 includes a fixed suction plate 310, a movable suction plate 320, a flip driving member 330 and a plurality of suction cups 340, wherein the upper surface of the fixed suction plate 310 is connected to the connecting tongue 221, and the movable suction plate 320 is hinged to one end of the fixed suction plate 310; the fixed end and the driving end of the flip driving member 330 are respectively connected to the connecting tongue 221 and the movable suction plate 320, and the flip driving member 330 can make the movable suction plate 320 flip up and down around one end of the fixed suction plate 310; the lower surfaces of the fixed suction plate 310 and the movable suction plate 320 are provided with suction cups 340, and the suction cups 340 are connected to a negative pressure air source, which can suck the topmost material plate 1000 in the material storage frame 100.

[0040] During the operation of the anti-adhesion loading device in the embodiment, the transverse movement module 210 first drives the suction assembly 300 to move above the material plate 1000 in the material storage frame 100, and then under the drive of the lifting drive 220, the suction assembly 300 moves downward, and the suction cups 340 on the lower surfaces of the fixed suction plate 310 and the movable suction plate 320 contact the uppermost material plate 1000 in the material storage frame 100, and the negative pressure source connected to the suction cups 340 is turned on to firmly adsorb the uppermost material plate 1000 in the material storage frame 100; then the lifting drive 220 drives the suction assembly 300 to move upward, and the transverse movement module 210 continues to work to load the material plate 1000 on the suction assembly 300 to the next workstation.

[0041] However, because the sheets 1000 are relatively thin, they are prone to static electricity or vacuum adsorption when stacked and stored, causing multiple sheets of material to stick together when being removed. For example, when the suction cup 340 absorbs the top sheet 1000 in the storage frame 100, two or more sheets 1000 may overlap and be simultaneously absorbed by the suction cup 340. When the sheets 1000 absorbed by the suction cup 340 are stuck together, the flip drive 330 drives the movable suction plate 320 to flip up and down around one end of the fixed suction plate 310. This flipping action generates a torque that separates the stuck sheet 1000 from the absorbed sheet 1000, and the stuck sheet 1000 eventually falls back into the storage frame 100. At the same time, the scraping mechanism 400 provided on the top of the storage frame 100 can also assist in separating stuck sheets 1000.

[0042] The anti-adhesion feeding device of the embodiment achieves a highly efficient anti-adhesion function through a unique design. The movable suction plate 320 in the suction assembly 300 can be flipped up and down under the action of the flip drive 330, thereby generating a torque to separate the adhering material sheet 1000 from the sucked material sheet 1000, ensuring that only one material sheet 1000 is successfully fed. At the same time, the scraping mechanism 400 at the top of the storage frame 100 further assists in separating the adhering material sheets 1000 during operation, allowing the excess material sheets 1000 to fall back into the storage frame 100. This multiple separation mechanism effectively solves the problem of material sheet 1000 adhesion caused by static electricity or vacuum adsorption, and improves the accuracy and production efficiency of feeding.

[0043] In some embodiments, the anti-adhesion feeding device of the embodiment further includes a tray lifting mechanism 110, such as Figure 4 and Figure 5 As shown, the tray lifting mechanism 110 includes a lifting drive 111 and a top block 112. The inside of the material storage frame 100 is provided with a lifting base (not shown). The material plates 1000 are stacked on the lifting base. The lifting base can move up and down vertically in the material storage frame 100, thereby driving the material plates 1000 stacked in the material storage frame 100 to move up and down. The lifting drive 111 is arranged on the frame. One end of the top block 112 is connected to the driving end of the lifting drive 111, and the other end is located below the lifting base and offset with the lower surface of the lifting base. The lifting drive 111 can form a beat with the process of the suction assembly 300 sucking the material plates 1000. When the suction assembly 300 takes away a material plate 1000, the lifting drive 111 drives the top block 112 to lift the lifting base by the height of a material plate 1000, thereby making the material plate 1000 at the top of the material storage frame 100 always at the top of the material storage frame 100.

[0044] Furthermore, in some embodiments, the tray lifting mechanism 110 further includes a lifting detection sensor 113. Figure 4 and Figure 7 As shown, the lift detection sensor 113 is located on one side of the top of the material storage frame 100 and is used to detect whether the topmost sheet 1000 in the material storage frame 100 has been lifted into place, thereby controlling the operating state of the lift drive 111. Compared to relying on beat coordination to drive the lift drive 111, the lift detection sensor 113 can monitor the position of the sheet 1000 in real time, ensuring that each lifting action can accurately lift the sheet 1000 to the predetermined position, effectively avoiding the position deviation of the sheet 1000 caused by beat error. At the same time, through real-time monitoring and feedback from the sensor, the system can promptly correct any position deviation, preventing errors from accumulating over multiple operations.

[0045] In some embodiments, the scraping mechanism 400 includes an air blowing assembly 410 and a brush assembly 420, and the air blowing assembly 410 and the brush assembly 420 are both located on both sides of the top of the material storage frame 100. Figure 4 and Figure 7 As shown, the brush portion of the brush assembly 420 extends from the side surface of the top of the material storage frame 100 toward the interior of the material storage frame 100. When the suction assembly 300 sucks the material sheet 1000 and starts to move upward, the brush of the brush assembly 420 contacts the side surface of the material sheet 1000, thereby assisting in separating the adhered material sheets 1000. The air blowing assembly 410 includes an air blowing pipe 411. The air blowing pipe 411 is provided with an air outlet facing the material storage frame 100. The air blowing pipe 411 is connected to a high-pressure air source. When the movable suction plate 320 is folded downward or the brush assembly 420 brushes the side surface of the material sheet 1000 on the suction cup 340, a gap will be generated between the material sheet 1000 sucked by the suction cup 340 and other adhered material sheets 1000. The high-speed air flow blown out of the air outlet enters these gaps, thereby assisting in separating the adhered material sheets 1000.

[0046] Furthermore, in some embodiments, the blowing assembly 410 further includes a blowing driving member 412, such as Figure 8 As shown, the air blow drive 412 can drive the air blow tube 411 to vibrate up and down. This vibration allows the airflow to enter the gaps at different angles and positions, increasing its coverage and penetration depth. It can more effectively direct the airflow into the tiny gaps between the sheets 1000, thereby more effectively separating the sheets 1000 from each other. The vibration also creates a pulsed effect in the airflow, which can apply periodic impact force to the stuck sheets 1000, increasing the power to separate the sheets 1000.

[0047] In some embodiments, the anti-adhesion feeding device of the embodiment further includes an adhesion detection mechanism 500. Figure 4 and Figure 5 As shown, the adhesion detection mechanism 500 is set on the frame and is located on one side above the material storage frame 100. The adhesion detection mechanism 500 is used to detect whether the material sheet 1000 sucked by the suction component 300 is adhered to other material sheets 1000. After the suction cup 340 sucks the material sheet 1000, it carries the material sheet 1000 to the detection area of ​​the adhesion detection mechanism 500. When the adhesion detection mechanism 500 detects that the carried material sheet 1000 is adhered, the suction component 300 will return to the top of the material storage frame 100, and through the coordinated work of the flip drive member 330, the blowing component 410 and the brush component 420, the adhered material sheet 1000 will fall back into the material storage frame 100.

[0048] Further, such as Figure 6As shown, in some embodiments, the adhesion detection mechanism 500 includes a detection driver 530, a signal transmitter 510, and a signal receiver 520. The detection driver 530 is disposed on a frame, and the signal transmitter 510 and the signal receiver 520 are vertically disposed at the driving end of the detection driver 530 relative to each other. The detection driver 530 can drive the signal transmitter 510 and the signal receiver 520 to move along the second horizontal direction. The signal emitted by the signal transmitter 510 passes through the sheet 1000 and is received by the signal receiver 520 to detect the thickness of the sheet 1000 between the signal transmitter 510 and the signal receiver 520. After the suction cup 340 absorbs the material sheet 1000 on the top layer of the material storage frame 100, the material suction component 300 first moves upward to drive the material sheet 1000 to the horizontal height of the spacing area between the signal generator and the signal receiver 520; then the detection drive 530 drives the signal transmitter 510 and the signal receiver 520 to move along the second horizontal direction, so that the material sheet 1000 adsorbed on the suction component 300 is located between the signal transmitter 510 and the signal receiver 520; then the signal transmitter 510 sends a detection signal, the detection signal passes through the material sheet 1000 and is received by the signal receiver 520. After the adhesion detection is completed, the detection drive component drives the signal transmitter 510 and the signal receiver 520 to move along the second horizontal direction. Return to the initial position; when the adhesion detection mechanism 500 detects that the thickness of the material sheet 1000 sucked by the suction component 300 is greater than the thickness of one sheet, the suction component 300 drives the material sheet 1000 back to the top of the material storage frame 100, and then drives the movable suction plate 320 to flip up and down through the flip drive 330, and the brush component 420 and the blowing component 410 assist in separation and other measures to separate the adhered material sheet 1000 from the material sheet 1000 sucked by the suction cup 340; then continue to repeat the above steps, when the adhesion detection mechanism 500 detects that the suction component 300 only carries one material sheet 1000, the transverse module 210 drives the suction component 300 to move laterally along the first path to load the material sheet 1000 to the next workstation.

[0049] In some embodiments, the material storage frame 100 is movably mounted on the machine frame. The material storage frame 100 is provided with a handle 120 for pushing and pulling, and the machine frame is provided with a plurality of stoppers for positioning or limiting the material storage frame 100 during pushing and pulling operations. The material storage frame 100 is designed to be removable. When the material plates 1000 need to be replenished, the operator can quickly withdraw the material storage frame 100 for replenishment without having to stop the machine or perform complicated operations, thereby improving work efficiency.

[0050] In the second aspect, the present application also provides a back cover loading machine, such as Figure 9As shown, it includes a transport line 600, a first material moving mechanism 700, a transfer table 800, a second material moving mechanism 900 and an anti-adhesion loading device according to any embodiment of the first aspect of the present application. The transport line 600, the first material moving mechanism 700, the transfer table 800 and the second material moving mechanism 900 are all arranged on the frame, and the transport line 600 is used to transport the clamping fixture 1100 to the loading station; the first material moving mechanism 700 is arranged on the side of the transport line 600, and is used to move the clamping fixture 1100 to the transport line 600; the transfer table 800 is located on the side of the anti-adhesion loading device of the embodiment, and is used to receive the material plate 1000 transported by the anti-adhesion loading device and adjust the placement direction of the material plate 1000; the second material moving mechanism 900 is located on the side of the transfer table 800 and the transport line 600, and is provided with a mechanical claw, which can grab the material plate 1000 on the transfer table 800, and transport the material plate 1000 to the top of the loading station, adjust the position and angle of the material plate 1000, and finally combine the material plate 1000 with the clamping fixture 1100 on the transport line 600.

[0051] It is understandable that the functions and principles of the back cover loading machine in the embodiment are based on the anti-adhesion loading device provided in the embodiment of the first aspect. By integrating the anti-adhesion loading device, it is possible to effectively solve the problem of adhesion of thin materials such as mobile phone back covers caused by static electricity or vacuum adsorption during the loading process, ensuring that only one back cover is loaded each time, thereby improving the accuracy of loading. To save space, this description will not be repeated here.

[0052] Furthermore, the rear cover loading machine of the embodiment further includes a first image detection module 910 and a second image detection module. Figure 9 As shown, the first image detection module 910 is arranged on the frame and is located above the loading station, and is used to obtain the first position information of the clamping fixture 1100 on the loading station; the second image detection module (not shown in the figure) is arranged on the frame and is located below the second material transfer mechanism 900, and is used to obtain the second position information of the material plate 1000 on the second material transfer mechanism 900; the position information of the clamping fixture 1100 and the material plate 1000 is obtained in real time through the first and second image detection modules, and the second material transfer mechanism 900 can accurately adjust the angle and position of the material plate 1000 to ensure the accurate docking of the material plate 1000 and the clamping fixture 1100, thereby improving the assembly accuracy.
