Description

Technical Field

[0001] The utility model relates to 3C product production and processing equipment, in particular to a feeding device, which is mainly used for feeding computer frame auxiliary materials. Background Art

[0002] In a laptop or desktop computer, the place where the display screen is installed has a frame, and various auxiliary materials, such as foam, labels, tapes, etc., need to be pasted on the frame. In the conventional method, it is all manually pasted, which is relatively inefficient. In order to improve the pasting efficiency, in the prior art, a robot is used for pasting. In order to achieve automated pasting, a corresponding workstation is generally set up, and then a conveyor belt is set at the front end of the workstation, and the product is conveyed to the front end of the corresponding workstation through the conveyor belt. Then a robot is set on each workstation, and the robot grabs the product on the conveyor belt to the corresponding workstation for corresponding auxiliary material assembly. After the assembly is completed, the robot is used to put the product back on the conveyor belt, and it is sent to the downward process through the conveyor belt.

[0003] Among them, when labeling, it is necessary to feed the label. The conventional labeling method is that when the product passes the label, one end of the label contacts the product, and then the label is peeled off and applied to the surface of the product. When labeling the computer frame, it is necessary to completely peel off the label in advance and wait for the robot to grab the label directly for labeling. One side of the label is the adhesive surface, and the other side is the identification surface. When the robot grabs it, it adsorbs the identification surface through the suction cup so that the adhesive surface is facing the product where it needs to be applied for labeling. Therefore, after the conventional label is peeled off, it will be on a platform surface with poor adhesion, waiting to be grabbed by the robot. However, since the robot's suction piece needs a certain amount of extrusion force to contact the label when it contacts the label, the robot's suction piece will apply pressure to the label, so that the label's adhesive surface and the platform are pressed tightly. Then, when the robot moves up, the suction force is likely to be less than the adhesive force with the platform, resulting in the robot being unable to suck the label away, or the label being torn, or part of the label being separated from the suction piece, affecting the subsequent labeling quality. Therefore, how to solve the above technical problems is the direction that technicians in this field need to work hard on. Summary of the invention

[0034] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0035] Example 1: See Figures 1 to 6 As shown, a feeding device comprises a frame 1, a discharge shaft 2 and a receiving shaft 3, wherein the receiving shaft 3 is arranged below the discharge shaft 2, a support plate 4 is arranged on the frame 1, and the support plate 4 is arranged on the right side between the receiving shaft 3 and the discharge shaft 2, and a transmission shaft 5 is rotatably mounted on the frame 1 below the support plate 4;

[0036] A stripping plate 6 is also provided on the right side of the support plate 4, and a material receiving platform 7 is provided on the right end of the stripping plate 6, and there is a gap between the left side of the material receiving platform 7 and the right side of the stripping plate 6;

[0037] A plurality of air blowing holes 8 are provided at intervals on the top surface of the material receiving platform 7, and the air blowing holes 8 are connected to an air source.

[0038] In this embodiment, it is mainly used for feeding labels. When in use, the manipulator moves to the top of the receiving table, absorbs the peeled label, and then applies the label to the product (computer frame) to be applied. In the process of use, the label roll is installed on the unloading shaft, and the label will be applied on the release paper. The end of the label paper 9 is pulled out from the unloading shaft, and the bottom of the label paper is against the support plate and then passes through the top surface of the stripping plate. It passes through the gap between the receiving table and the stripping plate, then bypasses from the bottom of the transmission shaft, and then the end of the label paper is wrapped around the receiving shaft, which is the moving track of the label paper. Among them, the bending angle of the label paper at the right end of the stripping plate will exceed 90 degrees, and preferably this bending angle exceeds 165°. Among them, a motor and a receiving shaft connection will be set on the frame to drive the receiving shaft to rotate. Of course, the motor and the unloading shaft can also be set to rotate to drive the unloading shaft to rotate to unwind the label paper. When in use, the motor drives the receiving shaft to rotate a certain angle, so that the label paper passes a certain distance from the right end of the peeling plate. When the label paper passes the right end of the peeling plate, the receiving shaft reels the release paper because the label is attached to the release paper. When passing the right end of the peeling plate, the label 10 is peeled off from the release paper. In this process, the label continues to move to the right, and the right end of the label moves to the receiving table. The process of label peeling and label grabbing by the robot 11 is as follows, see Figure 4a to Figure 4c :

[0039] A label is completely peeled off from the release paper and falls on the receiving table (after a label is completely peeled off from the release paper, the receiving shaft stops rotating and waits for the next label to be peeled off); then the robot moves to the top of the receiving table, sucks the label paper with the adsorption mechanism, and then sucks it off from the receiving table, and then applies it until the product needs to be applied. In the utility model, two rows of blowing holes are arranged, and the two rows of blowing holes are arranged with horizontal intervals. The multiple suction holes in each row are arranged with longitudinal intervals from front to back. The horizontal width of the two rows of blowing holes will be smaller than the width of a label. The air source will give positive pressure to the blowing holes, so that the blowing holes are always subjected to upward blowing force. When the label is peeled off and falls on the receiving table, the right end of the label is peeled off from the release paper and moves to the right. Due to the upward thrust given to the label by the blowing holes, the right end of the label will continue to move to the right, and its bottom will not temporarily contact the top surface of the receiving table (label The bottom surface of the label is the adhesive surface, which is sticky). When the right end of the label has completely passed the air hole for a certain distance, the upward blowing force given by the air hole cannot cover the downward force of the right end of the label's own weight, and the right end of the label will move downward. At the same time, the label will also move to the right. When the right end of the label falls and hits the receiving table, the left end of the label will also be completely separated from the release paper. Since the air hole will give the label an upward blowing force, the left end of the label will not contact the top surface of the receiving table. Then when the robot grabs the material, the robot moves down, and the adsorption mechanism at the bottom (such as suction The air hole or suction cup, preferably multiple air holes, first contacts the top surface of the left end of the label, and at the same time the suction mechanism applies negative pressure, and the robot continues to move down a part, at this time it will also press down a part of the left end of the label, but the bottom surface of the left end of the label has not yet contacted the receiving table. As the label is closer to the air hole, the greater the upward blowing force it receives, the upward blowing force received by the label plus the suction force on the robot makes the left end of the label completely sucked by the suction mechanism on the robot (at this time there is a vertical distance between the bottom surface of the left end of the label and the receiving table, this distance The distance value will be relatively small), and then the robot moves up. During the upward movement, the right end of the label is pulled up and away from the receiving table (the top surface of the receiving table is a smooth material that is easy to peel off, similar to the surface material of release paper, and the adsorption force will be greater than the adhesion force between the bottom surface of the right end of the label and the receiving table). Of course, when the robot moves up, it can also move to the right at the same time, so that the label is smoothly separated from the receiving table, and then moved to the top of the product (in this process, the label has two states, the first one: the top surface of the left end of the label is adsorbed by the adsorption mechanism, and the right end of the label is tilted downward, see Figure 5 As shown; The second type: Since the negative pressure of the adsorption mechanism is transmitted to the right end of the label, after the right end of the label leaves the receiving table, its right end moves up and is also adsorbed by the adsorption mechanism. At this time, the label and the bottom surface of the robot are in contact, see Figure 6 As shown), carry out the pasting work.

[0040] In other words, most of the right end of the label is attached to the receiving table, but the left end is blown up by the air hole. The robot first adsorbs the top surface of the left end of the label, and then as the robot moves up, it moves to the right relative to the receiving table to tear the label off the receiving table, thereby achieving label grabbing.

[0041] In this embodiment, an air cavity 25 is provided in the material receiving table, and the bottom of the blowing hole is connected to the air cavity 25. A first connecting hole 26 is also provided at the bottom of the material receiving table and is connected to the air cavity. The air source (the air source directly supplies air, and can be an air pump or other air source that can supply air) is connected to the first connecting hole through an air pipe, and is used to provide positive pressure air to the air cavity, so that the blowing hole blows out gas.

[0042] Furthermore, in order to ensure that only a small part of the label is in contact with the receiving table, a transverse driving mechanism is provided on the frame, a transverse slide rail 12 is provided on the frame 1, and the bottom of the receiving table 7 is slidably set on the transverse slide rail 12. The transverse driving mechanism is configured to drive the receiving table 7 to move horizontally, so that the receiving table 7 is set close to or away from the peeling plate 6.

[0043] The transverse driving mechanism is a cylinder, or the transverse driving mechanism is a combination of a transverse motor 13 and a ball screw 14. In this embodiment, the transverse driving mechanism is a combination of a transverse motor and a transverse ball screw, which is arranged at the bottom of the material receiving table, and the transverse ball screw is parallel to the side of the transverse slide rail. Both ends of the transverse ball screw are rotatably connected to the frame. The transverse motor is installed on the frame, and the transverse motor is connected to the left end of the transverse ball screw. A lower edge plate 27 is provided at the bottom of the material receiving table, which is connected to the transverse ball screw (the two can be screwed, or the lower edge plate is connected to the transverse ball screw through a ball screw pair and the transverse ball screw). The transverse motor drives the transverse ball screw to rotate, thereby driving the material receiving table to move left and right, so that it is close to or away from the stripping plate. Preferably, when the label is peeled off, after the right end of the label passes through the air hole and falls and contacts the receiving platform, and then the label continues to peel off and move to the right, if the label is slightly longer, or in other cases, in order to prevent the right end of the label from being unable to continue to move to the right after being bonded to the receiving platform, causing the label to fold and fail to ensure subsequent normal use, after the bottom surface of the right end of the label contacts the top surface of the receiving platform, the transverse drive mechanism drives the receiving platform to move to the right synchronously, and its moving speed is consistent with the peeling speed of the label (the label moves to the right at the same speed), so that after the label is completely peeled off from the release paper, the receiving platform also moves to the right, so that the label will not be folded, and only the right end contacts the receiving platform a little bit, which is convenient for the peeling of the label. Of course, it can also be applied to longer label paper. After the label is taken away, the receiving platform moves to the right and returns to its original position, waiting for the next material to be received.

[0044] Of course, the top surface of the receiving table will be at the lower right of the top surface of the peeling plate, and there is a slight height difference between the two. In this way, when the label is peeled to the right, the label peeling moves to the right and has inertia. Even if the receiving table does not move horizontally, it will not fold.

[0045] See also Figure 1 , 2 As shown, a limiting plate 15 is respectively provided on the front side and the rear side of the top surface of the support plate 4 .

[0046] The support plate can support the label paper during the moving and peeling process, and the setting of the limit plate can limit the moving trajectory of the label paper to prevent deviation.

[0047] See also Figure 1 , 2 As shown, a pressure plate 16 is rotatably mounted on each of the limit plates 15, and the pressure plate has a closed state and an open state; when the pressure plate is in the closed state, it is used to limit the upward movement freedom of the label paper to prevent the label paper from detaching from the support plate; when the pressure plate is in the open state, the upward movement limit of the label paper is released, so that the label paper can move upward and detach from the support plate, or the label paper can be placed on the support plate from bottom to top.

[0048] When the pressing plate 16 is in a closed state, the pressing plate 16 is disposed on the inner side of the limiting plate 15, and the bottom surface of the pressing plate 16 is disposed close to the top surface of the supporting plate 4;

[0049] When the pressing plate 16 is in the open state, the pressing plate 16 is rotatably disposed above the corresponding limiting plate 15 .

[0050] The top surface of the pressing plate 16 is rotatably connected to the top of the limiting plate 5 on the side via a hinge 17 .

[0051] In this embodiment, the setting of the pressing plate is such that when the pressing plate is closed, the pressing plate will be above the side of the label paper, limiting the label paper from leaving the top surface of the support table, thereby limiting the movement trajectory of the label paper, so that even if the winding speed of the label paper is less than the unwinding speed, the label will not fall off the support plate, ensuring that the label can be peeled off normally. At the same time, when a roll of labels is used up and the labels need to be replaced, the pressing plate is directly flipped over to open the pressing plate, so that the labels can be placed again. When the pressing plate is opened, the inner end of the pressing plate is directly flipped upward to open the pressing plate, so that the pressing plate is above the limiting plate, and the support plate is completely exposed. When the pressing plate needs to be closed, the inner end of the pressing plate is directly rotated toward the support plate, so that the pressing plate is rotated to the top of the support plate, and it is also limited by the limiting plate and the hinge, so that the pressing plate will not rest on the top surface of the label to prevent scratching the label.

[0052] See also Figures 1 to 3As shown, the left side of the stripping plate 6 is rotatably connected to the frame 1 via a connecting shaft 18, and the right end face of the stripping plate 6 is a stripping slope 19, which is arranged to be inclined upward from left to right, and the top of the stripping slope 19 is connected to the right side of the top of the stripping plate 6, and the bottom of the stripping slope 19 is connected to the bottom surface of the stripping plate 6.

[0053] The setting of the peeling slope can ensure the folding angle of the release paper, and the release paper and the peeling plate are attached together to ensure the peeling of the label and guide the peeling of the label.

[0054] See also Figure 1 , 2 As shown, the stripping plate 6 is further provided with a pull rod 20, the pull rod 20 is arranged parallel to the right side of the connecting shaft, and the two ends of the pull rod 20 are respectively arranged on the front end and the rear end of the stripping plate 6;

[0055] A tension spring 21 is provided at the front and rear ends of the stripping plate 6, respectively. The right end of each tension spring 21 is connected to the end of the pull rod 20, and the left end of the tension spring 21 is connected to the frame 1 below the connecting shaft 18. The tension spring 21 applies a downward tension to the pull rod 20, so that the stripping plate 6 is pressed against the frame 1. A bolt is provided at the front and rear ends of the frame, respectively. The bottom of each tension spring is connected to a bolt, and the top is connected to the end of the pull rod (the top of the tension spring at the front end is connected to the front end of the pull rod, and the top of the tension spring at the rear end is connected to the rear end of the pull rod).

[0056] In this embodiment, the stripping plate is rotatably connected to the frame through the connecting shaft, and is not fixed. At the same time, a pull rod and a tension spring are provided, and a downward pulling force is applied to the right end of the stripping plate through the tension spring and the pull rod, so that the stripping plate is against the frame. At the same time, during the label stripping process, the label paper will also give a downward thrust to the right end of the stripping plate to prevent the right end of the stripping plate from tilting during the stripping process, thereby ensuring the stripping quality. Among them, when it is necessary to expose the bottom of the stripping plate to facilitate the installation of the label paper (the end of the label paper passes between the stripping plate and the receiving table, and is connected to the receiving shaft from the bottom of the stripping plate), an upward turning force is directly applied to the right end of the stripping plate, so that the right end of the stripping plate is turned up, so that it is convenient to pass the label paper between the stripping plate and the receiving table and connect to the receiving shaft.

[0057] See also Figure 2As shown, a connecting plate 22 is further provided on the left side of the support plate 4, and a plurality of negative pressure holes 23 are provided on the connecting plate 22, and the negative pressure holes 23 are connected to the negative pressure source. A negative pressure cavity is provided on the connecting plate, and the bottom of the negative pressure hole is connected to the negative pressure cavity. A negative pressure connecting hole connected to the negative pressure cavity is provided on the bottom surface of the connecting plate, and the negative pressure source is connected to the negative pressure connecting hole through an air pipe, and the negative pressure source is a vacuum pump or other equipment capable of pumping air or vacuum. In this structure, if the unwinding shaft is only connected to the frame for rotation, and no motor is provided to actively drive the unwinding shaft for unwinding, or the unwinding speed is sometimes faster than the rewinding speed, in order to ensure that the label paper is tensioned as much as possible during the peeling process and to ensure the stability of the peeling, a connecting plate with a negative pressure hole is provided. When the label paper passes through the connecting plate, the negative pressure hole will give the label paper a downward suction force, so that the label paper at this location is tightly attached to the connecting plate, so that the label paper between the connecting plate and the peeling plate is always in a tensioned state, even if the label paper between the connecting plate and the unwinding shaft becomes loose, it will not affect the peeling quality. At the same time, the negative pressure given to the label paper by the negative pressure hole will not affect the rightward movement of the label paper, prevent the label paper from being pulled off, and ensure the peeling stability and quality of the label. In this way, compared with the conventional tension adjustment roller, the stability is better, and the space occupied will be relatively small. In addition, the negative pressure hole can also make the label paper passing through the connecting plate flat, ensuring the peeling quality of the label.

[0058] See also Figure 1 , 2 As shown, the top surfaces of the connecting plate, the supporting plate and the stripping plate are arranged on the same plane;

[0059] An intermediate shaft 24 is rotatably mounted on the frame on the left side of the connecting plate 22, and the bottom surface height of the intermediate shaft 24 is not higher than the top surface height of the connecting plate 22. Preferably, the bottom surface of the intermediate shaft is flush with the top surface of the connecting plate, and after the end of the label paper is released from the unloading shaft, it first goes around the bottom of the intermediate shaft from the left side, and then passes through the connecting plate, the support plate, the stripping plate, the bottom surface of the transmission shaft in sequence, and then connects to the receiving shaft. The setting of the intermediate shaft allows the label paper to be stably transported to the connecting plate, and then rolled up by the receiving shaft after passing through the support plate and the stripping plate.
