Description

Technical Field

[0003] In the processing of FPC in the prior art, an automatic loading and unloading device is generally used. The displacement mechanism of the automatic loading and unloading device drives the suction mechanism to move as a whole, and the FPC on the transmission belt is grabbed by the suction cup, and then moved to the processing area for processing. However, when the suction cup is used for grabbing, the bottom suction cup is fixed, so that only FPCs of the same style can be sucked. When sucking FPCs of different styles during grabbing, some suction cups cannot fall on the FPC, resulting in the inability to form negative pressure during suction, resulting in the inability to lift it up. At the same time, the suction cup position can be adjusted to suck FPCs of different sizes, but it needs to be adjusted every time a different style of FPC is changed, which reduces its working efficiency and is not conducive to loading and unloading. Therefore, it needs to be improved. Summary of the invention

DETAILED DESCRIPTION

[0029] 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.

[0030] Example 1

[0031] like Figures 1 to 7 As shown, it is the first embodiment of the present invention, which provides a high-efficiency automatic loading and unloading device, including a loading and unloading mechanism 1, a displacement mechanism 2 is arranged at the top of the inner wall of the loading and unloading mechanism 1, a material taking component 3 is connected to the bottom of the displacement mechanism 2, a suction mechanism 4 is arranged at the bottom of the material taking component 3, an inspection component 5 is arranged at the top of the material taking component 3, and fixed structures 6 are arranged on both sides of the inspection component 5;

[0032] The material taking component 3 includes a mounting frame 301, the inner wall of the mounting frame 301 is provided with a connecting pipe 302, the connecting pipe 302 is evenly distributed on the mounting frame 301, the inner cavity of the connecting pipe 302 is movably connected with a moving block 303, the moving block 303 is provided with an air inlet 304, the outside of the connecting pipe 302 is connected with a transfer pipe 305 located outside the air inlet 304, the outside of the transfer pipe 305 is connected with an air pipe 306, the top of the air pipe 306 extends to the outside of the mounting frame 301 and is connected to the air pump;

[0033] The inspection assembly 5 includes a connecting plate 501, which is movably sleeved on the outside of the mounting frame 301. A piston rod 502 located in the inner cavity of the connecting tube 302 is arranged at the bottom of the connecting plate 501. The piston rod 502 is elastically connected to the connecting plate 501 through a spring 2 504. An air passage 503 located outside the moving block 303 is opened inside the connecting tube 302, and both ends of the air passage 503 extend to the upper and lower parts of the moving block 303.

[0034] The fixing structure 6 includes a pressing block 605, the bottom of which is connected to the inner wall of the loading and unloading mechanism 1;

[0035] When the FPC is loaded, the FPC to be processed is placed on the loading and unloading mechanism 1, and the displacement mechanism 2 drives the material picking component 3 and the suction mechanism 4 to move, so that the suction mechanism 4 contacts the surface of the FPC, and the bottom of the suction mechanism 4 is sealed with the FPC. As it moves downward, the two sides of the connecting plate 501 are squeezed by the pressure block 605, driving the connecting plate 501 to stop moving as a whole. When the bottom of the suction mechanism 4 is not completely closed, the connecting plate 501 drives the piston rod 502 and the spring 2 504 to move upward as a whole, and drives the moving block 303 to move upward through the piston rod 502, so that the end of the air inlet 304 is misaligned with the end of the transfer tube 305, so that when the air pump is started later, the air flow cannot pass through this connecting tube 302, and when the bottom of the suction mechanism 4 is completely in contact with the The FPC is in contact with each other, and the bottom of the suction mechanism 4 is sealed with the FPC. As the connecting plate 501 moves, the pressure difference between the inner cavity of the suction mechanism 4 and the outside is formed, which makes it impossible to drive the piston rod 502 to move upward as a whole, causing its moving block 303 to remain stationary. Then, the air pump is started to extract the gas in the connecting pipe 302, thereby further forming a stable pressure difference, thereby lifting the FPC from the loading and unloading mechanism 1 and moving it to the processing area. The air pump is controlled to supply air to drop the FPC into the processing area for processing, and then the unloading of the FPC is completed as a whole through the material taking component 3 on the other side, so as to detect whether the suction mechanism 4 completely absorbs the FPC, so that it is convenient to absorb FPCs of different sizes, thereby facilitating the loading and unloading operations of the FPC.

[0036] Example 2

[0037] like Figure 3 and Figure 5 As shown, this embodiment includes the features of the embodiment 1, and the distinguishing technical features are that the loading and unloading mechanism 1 includes a box body 101, and a feeding structure 102 and a discharging structure 103 are respectively arranged on both sides of the box body 101, and the feeding structure 102 and the discharging structure 103 are extended to the outside of the box body 101;

[0038] When the operator is processing the FPC, the FPC to be processed is placed on the feeding structure 102, and then the FPC is transported to the inner cavity of the box 101 through the feeding structure 102. The displacement mechanism 2 controls the material picking component 3 and the suction mechanism 4 to complete the adsorption of the FPC, so that the FPC is transferred to the processing area, and then the processed FPC is adsorbed by the material picking component 3 and the suction mechanism 4 on the other side, and is sent to the discharging structure 103, and then transmitted to the outside of the box 101 through the discharging structure 103 for subsequent steps.

[0039] The inner cavity of the box body 101 is provided with a workbench 104 located between the feeding structure 102 and the discharging structure 103, and a stopper 105 is provided on the outer side of the top of the workbench 104;

[0040] The workbench 104 is used to process the delivered FPC. At the same time, when the material taking component 3 and the suction mechanism 4 come over, the stopper 105 arranged on the outside releases the clamping connection of the fixed structure 6 through the stopper 105 to prevent the adsorption from being unstable.

[0041] The displacement mechanism 2 includes a driving structure 201, the outer side of the driving structure 201 is connected to the inner wall of the box 101, a movable block 202 is threadedly sleeved on the outer surface of the driving structure 201, a pneumatic cylinder 203 is arranged at the bottom of the movable block 202, a connecting frame 204 is connected to the bottom of the pneumatic cylinder 203, and the bottom of the connecting frame 204 is connected to the outer side of the mounting frame 301;

[0042] By starting the driving structure 201, the movable block 202 is driven to move, and the movable block 202 drives the material picking components 3 on both sides to move horizontally at equal intervals as a whole. When the material picking component 3 on one side moves above the workbench 104, the pneumatic cylinder 203 is started to drive the connecting frame 204 and the material picking component 3 to move downward, completing the adsorption of the FPC and the processed FPC, so that it can be sent for processing or unloading.

[0043] The suction mechanism 4 includes a sleeve 401, the inner wall of the sleeve 401 is movably connected to the outer side of the connecting pipe 302, the outer surface of the sleeve 401 is movably connected to the inner wall of the mounting frame 301, and a suction cup 402 is provided at the bottom of the sleeve 401;

[0044] When the pneumatic cylinder 203 drives the material taking component 3 and the suction mechanism 4 to move downward as a whole, the bottom of the suction cup 402 contacts the FPC, and then with continuous movement, the sleeve 401 moves toward the inside of the mounting frame 301, and at the same time, the gas in the inner cavity of the sleeve 401 is gradually discharged from the outside of the suction cup 402. As the mounting frame 301 moves, the two sides of the connecting plate 501 are squeezed with the pressing block 605, driving the connecting plate 501 to stop running. At this time, the mounting frame 301 continues to move as a whole. Through the connection between the second spring 504, when the suction cup 402 is completely in contact with the FPC, due to the pressure difference between the connecting pipe 302, the sleeve 401 and the FPC, the piston rod 502 cannot move, the second spring 504 is stretched, and the moving block 303 is fixed here, so that the FPC is adsorbed by the air pump, the air pipe 306 and the transfer pipe 305;

[0045] When the bottom of the suction cup 402 is not completely adsorbed to the FPC, the connecting plate 501 is blocked by the pressing block 605, and the sleeve 401 and the connecting tube 302 are in a ventilated state, so that no pressure difference is generated. The elastic force of the second spring 504 adsorbs the piston rod 502 on the connecting plate 501, and the connecting plate 501 drives the piston rod 502 and the moving block 303 to move, so that the air inlet 304 in the moving block 303 is misaligned with the transfer tube 305. When the air pump is started, the air flow will not pass through the connecting tube 302, so that it will not generate adsorption force or air leakage, thereby avoiding affecting the adsorption effect.

[0046] This makes it easier to load and unload FPCs of different sizes without having to adjust the position of the suction cup 402, thereby improving work efficiency.

[0047] Among them, a spring 403 is arranged on the outside of the sleeve 401, and the other end of the spring 403 is connected to the outside of the mounting frame 301;

[0048] When the adsorbed FPC moves to the top of the workbench 104, the air pump is turned off, and the gas is introduced into the inner cavity of the connecting tube 302 along the air pipe 306 and the transfer tube 305, so that the adsorption of the FPC is released, and the FPC falls onto the workbench 104. The material picking component 3 and the suction mechanism 4 are reset as a whole through the displacement mechanism 2. At this time, the elastic force of the spring 403 drives the squeezed sleeve 401 to reset, so that it is convenient for subsequent continued use. At the same time, the design of the sleeve 401 and the spring 403 makes it possible to adsorb FPCs of different thicknesses, so that they can be loaded and unloaded.

[0049] Among them, the outer side of the connecting plate 501 is connected to a spring 505, and the other end of the spring 505 is connected to the inner wall of the mounting frame 301;

[0050] When the connecting plate 501 is blocked by the pressure block 605, the connecting plate 501 continuously squeezes the spring four 505. Then, when the FPC is delivered, the fixing of the connecting plate 501 is released. At this time, since the spring four 505 is in an extruded state, a downward pressure will be applied to the connecting plate 501, making it easy to drive the connecting plate 501 to reset, so as to facilitate the subsequent loading and unloading.

[0051] Example 3

[0052] like Figure 6 and Figure 7 As shown, this embodiment includes the features of the embodiment 1, and the distinguishing technical features are that the fixing structure 6 includes a clamping block 601, the outer surface of the clamping block 601 is movably connected to the inner wall of the connecting plate 501, both sides of the clamping block 601 extend to the outer wall of the connecting plate 501, and a spring 3 602 is arranged inside the clamping block 601;

[0053] At this time, since the spring three 602 is in a squeezed state, it will apply outward pressure to the block 601, making it easier to drive the block 601 to move out from the inside of the connecting plate 501.

[0054] A bayonet 603 is provided inside the connecting tube 302, and the size of the bayonet 603 is adapted to the end of the clamping block 601;

[0055] When the connecting tube 302 moves downward as a whole, the connecting plate 501 is squeezed by the pressing block 605, driving the connecting plate 501 to move upward compared to the connecting tube 302. When the adsorption of the FPC is completed, the clamping block 601 is affected by the elastic force of the spring three 602, driving the clamping block 601 to be clamped into the inside of the clamping port 603, so that the connecting plate 501 is clamped as a whole at the position of the clamping port 603, so as to avoid air leakage when transferring the FPC.

[0056] Wherein, both sides of the connecting pipe 302 are provided with a slot 604 located outside the bayonet 603, and the size of the slot 604 is adapted to the size of the stopper 105;

[0057] When the suction mechanism 4 for adsorbing the FPC moves to the top of the workbench 104, the pneumatic cylinder 203 drives the material picking component 3 and the suction mechanism 4 to move downward as a whole, and then the stopper 105 moves to the inside of the card slot 604, and then the block 105 squeezes the card block 601, so that the card block 601 is disassembled and squeezed into the inner cavity of the connecting plate 501. At the same time, the elastic force of the spring four 505 drives the connecting plate 501 to reset to prevent it from positional displacement, and turns off the air pump to allow it to send the FPC at the bottom to the top of the workbench 104 for processing.

[0058] The working principle and use process of the present invention:

[0059] First, when the operator is adsorbing FPCs of different sizes, the FPC to be processed is placed on the feeding structure 102, and the feeding structure 102 drives the FPC to move to the inner cavity of the box 101, and then the driving structure 201 drives the material picking component 3 to move to the top of the feeding structure 102, and the pneumatic cylinder 203 is started to drive the material picking component 3 and the suction mechanism 4 to move downward as a whole, and the bottom of the suction cup 402 contacts the FPC first, and then continues to move, squeezing the sleeve 401 into the mounting frame 301. Through this distance, it can be suitable for loading and unloading FPCs of different thicknesses, and then the bottom of the connecting plate 501 is pressed. 605 blocks, and then the connecting plate 501 moves upward with the mounting frame 301 as the reference. At this time, due to the compression of the suction cup 402 and the FPC or the feeding structure 102, when the suction cup 402 and the FPC are not completely closed, the connecting plate 501 drives the piston rod 502 and the spring 2 504 to move upward as a whole. Due to the air circulation inside the connecting tube 302 and the sleeve 401, no pressure difference is generated. The piston rod 502 and the moving block 303 are driven upward by the connecting plate 501, so that the air inlet 304 and the transfer tube 305 are misaligned. When the air pump is started later, the air flow cannot pass through this connecting tube 302. When the bottom of the suction mechanism 4 is completely closed with the FPC, When the connecting plate 501 moves upward, the piston rod 502 cannot be driven to move upward as a whole due to the pressure difference between the inner cavity of the sleeve 401 and the connecting pipe 302 and the outside, causing the moving block 303 to remain stationary. Then, the air pump is started to extract the gas in the connecting pipe 302, thereby further increasing the adsorption force. At this time, the connecting plate 501 moves to the outside of the bayonet 603, and is fixed as a whole by the clamping of the clamping block 601, so that the FPC is transferred by the pneumatic cylinder 203 and the driving structure 201, so that it moves to the top of the workbench 104 for unloading, and then the stopper 105 is clamped when it moves downward. It is connected to the inside of the card slot 604, and the card block 601 is squeezed into the inner cavity of the connecting plate 501 to release the fixation of the connecting plate 501, thereby driving the connecting plate 501 to reset through the spring four 505, and at the same time, the air pump is turned off to release the FPC adsorbed below, and the driving structure 201 and the pneumatic cylinder 203 reset the material picking component 3 and the suction mechanism 4 to pick up materials again. At the same time, the material picking component 3 and the suction mechanism 4 on the other side in the opposite direction unload the processed FPC, so as to detect whether the suction mechanism 4 completely adsorbs the FPC, so that it is convenient to adsorb FPCs of different sizes, and complete the automatic loading and unloading operation of the FPC.
