Description

Technical Field

[0001] The utility model relates to automation equipment, in particular to a sandpaper auxiliary stripping device. Background Art

[0002] In some polishing fields, when sandpaper is used to polish the surface of a product, such as using sandpaper to polish the burrs on the surface, or to polish the uneven areas on the surface, manual polishing is generally used. Since the efficiency of manual polishing is relatively low, the labor intensity of the operator is relatively high, and the consistency of manual polishing is relatively poor, therefore, currently, for batch products, a robot is generally used for automatic polishing. Among them, for products with higher requirements, such as 3C equipment and the polishing of the metal shell of a laptop computer, after the sandpaper is polished on a product, or after polishing a certain number of products, the wear of the sandpaper reaches a certain length, when another product is polished later, it will lead to poor polishing effect of subsequent products. Therefore, the sandpaper generally needs to be replaced. The conventional replacement method is that the robot extends, and then the sandpaper is manually torn off from the robot, and then the sandpaper is manually attached to the polishing self-adhesive disc of the robot. Since the grinding self-adhesive disc has a certain stickiness to the sandpaper, it is time-consuming and laborious for the operator to tear off the sandpaper. Sometimes, improper operation may easily scratch the sandpaper self-adhesive disc, affecting the service life of the sandpaper self-adhesive disc. Summary of the invention

[0030] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0031] Example 1: See Figure 1-4 As shown, a sandpaper-assisted stripping device comprises a positioning frame 1 and a stripping plate 2, wherein the middle of the positioning frame 1 has a cavity 3 penetrating through the front and rear ends;

[0032] The stripping plate 2 is installed on the front side wall of the positioning frame 1, and the stripping plate 2 is arranged on the front side of the cavity 3, and there is a vertical distance between the top of the stripping plate 2 and the top of the cavity 3;

[0033] The top surface of the stripping plate 2 is a stripping surface 4 which is arranged downwardly and tilted from the front to the rear, and a stripping angle 5 is formed between the stripping surface 4 and the front end surface of the stripping plate 2;

[0034] A convex plate 6 extending forward is provided on the top front side of the positioning frame 1, and the convex plate 6 is arranged just above the stripping surface 4, and a stripping blanking distance 7 is formed between the bottom surface of the convex plate 6 and the stripping surface 4;

[0035] The front side of the stripping plate 2 is disposed at the front side below the convex plate 6 , and there is a longitudinal distance between the front side of the stripping plate 2 and the front side of the convex plate 6 .

[0036] In this embodiment, it is used to assist in the peeling of the sandpaper on the manipulator. The spacing value of the longitudinal spacing is equal to the thickness of the sandpaper. When the sandpaper is peeled, a grinding self-adhesive disc is installed on the manipulator, and the sandpaper is adhered to the grinding self-adhesive disc. The manipulator drives the grinding self-adhesive disc to be arranged horizontally, that is, the axis of the grinding self-adhesive disc is arranged perpendicular to the front side of the peeling plate, and then the sandpaper is against the front end surface of the convex plate. At this time, the connection between the sandpaper and the grinding self-adhesive disc is directly above the peeling angle, and then the manipulator drives the grinding self-adhesive disc to move downward. In this process, the peeling angle is inserted between the sandpaper and the grinding self-adhesive disc, and the sandpaper is peeled off from the grinding self-adhesive disc through the peeling angle. During the peeling process of the sandpaper, the sandpaper is guided by the peeling surface and falls backward from the cavity to ensure the tearing effect.

[0037] See also Figure 1-4 As shown, the bottom surface of the protruding plate 6 is a guiding inclined surface 8 , and the guiding inclined surface 8 is arranged parallel to and just above the peeling surface 4 .

[0038] The setting of the guide bevel is that when the sandpaper is peeled off from the grinding self-adhesive disc, the bottom of the peeled sandpaper may curl upward. Therefore, the setting of the guide bevel can limit the curling of the sandpaper to ensure that it is peeled off normally and falls normally from the peeling gap after being peeled off.

[0039] At least one limiting screw hole 9 is respectively provided on the front side surface of the positioning frame 1 on the left and right sides of the cavity 3, and at least one vertical strip through groove 10 matching the limiting screw hole is respectively provided on the left and right sides of the stripping plate 2, and a limiting bolt 11 is inserted in each of the vertical strip through grooves 10, and the rear end of the limiting bolt 11 passes through the vertical strip through groove 10 and is screwed to the corresponding limiting screw hole, and the limiting bolt 11 locks the stripping plate 2 and installs it on the positioning frame 1.

[0040] The length of the vertical strip through groove is greater than the diameter of the limiting bolt.

[0041] When the limiting bolt is loosened, the stripping plate can move vertically relative to the limiting bolt via the vertical strip through slot.

[0042] The stripping plate is locked and installed on the positioning frame through the limiting bolts, and the vertical strip through groove is set to adjust the distance between the stripping plate and the convex plate to adjust the spacing value of the stripping blanking spacing.

[0043] See also Figure 1 , 2 As shown, two vertically spaced limit screw holes are respectively provided on the left and right sides of the front end surface of the positioning frame, and two vertical strip through grooves are respectively provided on the left and right sides of the stripping plate. The two vertical strip through grooves arranged on the left side of the stripping plate are respectively opposite to the two limit screw holes on the left side of the positioning frame; the two vertical strip through grooves arranged on the right side of the stripping plate are respectively opposite to the two limit screw holes on the right side of the positioning frame.

[0044] Two limiting screw holes and two vertical strip through grooves are used on each side to ensure that after the stripping plate and the positioning frame are connected, the stripping plate and the positioning frame are tightly fitted together, so as to ensure that when the grinding self-adhesive disc moves downward during the stripping process, the stripping plate is always parallel to the grinding self-adhesive disc, and the grinding self-adhesive disc will not be blocked and damaged by the inclination of the stripping plate.

[0045] The front end of the peeling surface is connected to the front end surface of the peeling plate, and the rear end of the peeling surface is connected to the rear end surface of the peeling plate. In this way, the peeling surface and the front end of the peeling plate form a peeling bevel, and the peeling surface and the rear end of the peeling plate are connected to ensure that the sandpaper falls smoothly from the cavity after being peeled off, which is convenient for the unified collection of the sandpaper after being peeled off.

[0046] See also Figure 2 , 4 As shown, the cavity passes through the front end surface and the rear end surface of the positioning frame;

[0047] The rear end surface of the positioning frame 1 is provided with an upper groove 12 and a lower groove 13, the bottom of the upper groove 12 is connected to the top of the cavity 3, the top of the lower groove 13 is connected to the bottom of the cavity 3, and the upper groove 12 is arranged directly above the lower groove 13;

[0048] A pair of through-beam sensors 14 is also provided, wherein a transmitting end 14 - 1 of the through-beam sensor 14 is installed in the lower groove 13 , and a receiving end 14 - 2 of the through-beam sensor 14 is installed in the upper groove 12 , and the transmitting end 14 - 1 of the through-beam sensor 14 is arranged opposite to the receiving end 14 - 2 of the through-beam sensor 14 .

[0049] By setting up the through-beam sensor, during the process of sandpaper being peeled off, it can detect whether the sandpaper passes through the cavity smoothly through the through-beam sensor. If the through-beam sensor does not detect the sandpaper being peeled off when the robot performs the sandpaper peeling action, it can feed back the data to the robot or the back-end server to notify the staff to check whether there is any problem in time.

[0050] The upper groove and the lower groove are respectively connected to the top and the bottom of the center of the cavity, so that the sandpaper can be detected by the beam sensor when it is peeled off and passes through the cavity.

[0051] See also Figure 1 , 4 As shown, a photoelectric sensor mounting hole 15 is provided in the middle of the front end surface of the convex plate, and a photoelectric sensor (not shown in the photoelectric sensor figure) is installed in the photoelectric sensor mounting hole 15, and the detection end of the photoelectric sensor is arranged forward. With the presence of the mounting hole and the photoelectric sensor, when the sandpaper is at the front side of the convex plate and is ready to move down to peel off at an angle, the photoelectric sensor can detect that the sandpaper peeling action is ready, and it will feed back the data to the through-beam sensor, which is used to detect whether the subsequent sandpaper passes through the cavity normally. If it does not pass, it means that the sandpaper peeling is unsuccessful and there is a problem. The data is fed back to the controller of the manipulator or the back-end server in a timely manner, and the workers are notified to repair or check in a timely manner.
