[0033] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0034] In a typical implementation of the present invention, Figure 1-Figure 6 As shown, a common positioning platform for rear window glasses of multiple vehicle types is proposed, comprising: a base 1, a sliding platform 2 and an identification and positioning mechanism 3, wherein the sliding platform 2 is slidably set on the base 1, and the identification and positioning mechanism 3 comprises a first identification and positioning mechanism and a second identification and positioning mechanism, the first identification and positioning mechanism and the second identification and positioning mechanism are relatively fixedly set on the sliding platform 2 and can move with the sliding platform 2, and the first identification and positioning mechanism and the second identification and positioning mechanism cooperate with each other for identification, positioning and support of glass.

[0035] Specifically, the base 1 is a frame structure, which is welded by several rectangular steel pipes. After overall processing, slide rails 11 are installed on both sides of the top of the base 1. The mounting surfaces of the two slide rails 11 are coplanar and the axes of the two slide rails 11 are parallel. Twelve cylinders and limit blocks are installed in the middle of the top. The four corners of the bottom of the base 1 are provided with expansion bolt mounting holes for fixed installation of the base 1.

[0036] The sliding table 2 is connected to the cylinder 12, and the sliding table 2 includes a slider 21, a mounting plate 22, a suction cup 23 and a bracket 24. Specifically, the bottom of the sliding table 2 is fixedly provided with a slider 21, and the bottom of the sliding table 2 is slidably connected to the slide rail 11 on the base 1 through the slider 21. A bracket 24 is fixedly provided on the sliding table 2, and the bracket 24 is tilted. There are two mounting plates 22, and the two mounting plates 22 are relatively fixedly arranged on the bracket 24. An identification and positioning mechanism 3 is fixedly installed on each mounting plate 22, and a plurality of suction cups 23 are also fixedly provided on each mounting plate 22 for adsorbing and fixing the glass.

[0037] The mounting plate 22 is parallel to the bracket 24, that is, the mounting plate 22 is also tilted. The two mounting plates 22 are coplanar and form an angle of 60° with the horizontal plane to be more ergonomic. The mounting plate 22 is a U-shaped plate structure. Specifically, an avoidance groove 221 is processed on the mounting plate 22. The avoidance groove 221 is an upper opening structure to facilitate the mounting plate 22 to avoid the robot, facilitate the robot to grab the glass, and avoid collision damage between the robot and the mounting plate 22.

[0038] Each mounting plate 22 is installed with an identification and positioning mechanism. Specifically, a first identification and positioning mechanism is installed on one mounting plate 22, and a second identification and positioning mechanism is installed on the other mounting plate 22. The first identification and positioning mechanism has the same overall structure as the second identification and positioning mechanism and is symmetrically arranged relative to the center line of the bracket 24.

[0039] like Figure 2As shown, the first identification and positioning mechanism and the second identification and positioning mechanism have the same structure, both of which include a first positioning group, a second positioning group, a third positioning group, a first identification unit 34, a second identification unit 35 and a third identification unit 36. The first positioning group on the first identification and positioning mechanism and the second identification and positioning mechanism are both adjacent to the center line of the bracket 24, that is, the first identification and positioning mechanism and the second identification and positioning mechanism are the first positioning group, the second positioning group and the third positioning group from the center line of the bracket 24 outward in sequence, and there is a set spacing between the first positioning group and the second positioning group, and between the second positioning group and the third positioning group. The heights of the first positioning group, the second positioning group and the third positioning group increase in sequence, that is, the height of the first positioning group is lower than that of the second positioning group, and the height of the second positioning group is lower than that of the third positioning group, so as to be used for positioning and placing glass of different sizes; the first identification unit 34 is installed at the first positioning group, the second identification unit 35 is installed at the second positioning group, and the third identification unit 36 ​​is installed at the third positioning group, so as to be used for automatic identification of glass size.

[0040] To facilitate understanding, the first identification and positioning mechanism is described in detail. The first positioning group in the first identification and positioning mechanism includes a plurality of first positioning columns 31, which are arranged in an L shape along the inclination direction of the mounting plate 22; the second positioning group includes a plurality of second positioning columns 32, which are arranged in an L shape along the inclination direction of the mounting plate 22; the third positioning group includes a plurality of third positioning columns 33, which are arranged in an L shape along the inclination direction of the mounting plate 22, that is, the first positioning group, the second positioning group and the third positioning group are all L-shaped, so as to support and limit the bottom side corners of the glass.

[0041] The structures of the first positioning group, the second positioning group and the third positioning group on the second identification and positioning mechanism are the same as those of the first identification and positioning mechanism, and will not be elaborated on here. The first positioning group, the second positioning group and the third positioning group on the second identification and positioning mechanism cooperate with the corresponding first positioning group, the second positioning group and the third positioning group on the first identification and positioning mechanism to support and limit the corners on both sides of the bottom of the glass (tilted).

[0042] The height of the first positioning column 31 is lower than the height of the second positioning column 32 adjacent thereto, and the height of the second positioning column 32 is lower than the height of the third positioning column 33 adjacent thereto. The first positioning column 31, the second positioning column 32 and the third positioning column 33 have the same structure. This embodiment is described in detail with reference to the first positioning column 31. Figure 3As shown, the first positioning column 31 includes a limiting column 311, a positioning block 312, a screw 313 and a column 314. The column 314 is fixedly arranged on the corresponding mounting plate 22. The column 314 is perpendicular to the plane of the mounting plate 22. A threaded hole is opened at the top of the column 314. The screw 313 is threadedly installed in the threaded hole at the top of the column 314. The positioning block 312 is fixedly installed at the top of the screw 313. The limiting column 311 is fixedly installed on the positioning block 312. The upper surface of the positioning block 312 is a plane so as to contact the glass through the plane to support the glass. The limiting column 311 is a columnar structure made of MC nylon (i.e., cast nylon), which plays the role of limiting the glass, increases the friction resistance, and avoids collision damage to the glass.

[0043] The setting of the screw rod 313 can adjust the height and direction of the positioning block 312 and the limiting column 311 according to needs to improve their adaptability. The screw rod 313 can also be equipped with a locking nut to improve its installation stability.

[0044] The height of the first positioning column 31 is lower than that of the second positioning column 32 adjacent to it, and the height of the second positioning column 32 is lower than that of the third positioning column 33 adjacent to it. Specifically, the top of the upper limit positioning column 311 of the first positioning column 31 is lower than the upper surface of the positioning block 312 on the second positioning column 32, and the top of the upper limit positioning column 311 of the second positioning column 32 is lower than the upper surface of the positioning block 312 on the third positioning column 33, thereby effectively avoiding interference between adjacent positioning columns.

[0045] The first recognition unit 34 , the second recognition unit 35 and the third recognition unit 36 ​​are all travel switches for recognizing glass.

[0046] It is understandable that the cylinder 12 and the identification unit are both connected to the control center to facilitate human control and coordination between the positioning platform and the robot arm.

[0047] The specific working principle is:

[0048] Insert the slider 21 of the sliding platform 2 into the slide rail 11 of the base 1, and after the sliding platform 2 is connected, fix the base 1 with expansion bolts;

[0049] like Figure 4-Figure 6 As shown, firstly, the first glass 4 is placed in the first positioning group, and the screw 313 of the first positioning column 31 is adjusted so that the positioning blocks 312 of all the first positioning columns 31 firmly support the first glass 4 and make the first glass 4 parallel to the plane of the mounting plate 22, and the direction of the limiting column 311 is adjusted so that the cylindrical surface limits the edge line of the glass and adjusts the glass to a horizontal center position, and at this time, the position of the first identification unit 34 and the corresponding suction cup 23 are adjusted according to the position of the first glass 4;

[0050] Similarly, put the second glass 5 into the second positioning group, adjust the screw 313 of the second positioning column 32, so that the positioning blocks 312 of all the second positioning columns 31 firmly support the second glass 5 and make the second glass 5 parallel to the plane of the mounting plate 22, adjust the direction of the limiting column 311, so that the cylindrical surface limits the edge of the glass to adjust the glass to the horizontal center position, and at this time adjust the position of the second identification unit 35 and the corresponding suction cup 23 according to the position of the second glass 5;

[0051] Put the third glass 6 into the third positioning group, adjust the screw 313 of the third positioning column 33, so that the positioning blocks 312 of all the third positioning columns 33 firmly support the third glass 6 and make the third glass 6 parallel to the plane of the mounting plate 22, adjust the direction of the limiting column 311, so that the cylindrical surface limits the edge of the glass to adjust the glass to a horizontal center position, and at this time adjust the position of the third identification unit 36 ​​and the corresponding suction cup 23 according to the position of the third glass 6;

[0052] When the positioning platform is officially put into use after debugging, the cylinder 12 controls the sliding platform 2 to slide out along the track 11, and the operator smoothly puts the first type of glass 4 into the first positioning group. The first recognition unit 34 senses and outputs a signal, and the corresponding suction cup 23 exhausts and sucks the first type of glass 4 tightly.

[0053] After checking and confirming, the operator controls the sliding table 2 to slide along the track 11 through the cylinder 12, and the industrial robot grabs the first glass 4 according to the PLC signal to apply glue and bond;

[0054] The operator controls the sliding platform 2 to slide out, selects the corresponding rear window glass according to the current vehicle model, puts it into the corresponding positioning group and repeats the above steps.

[0055] It should be noted that, in this embodiment, the length of the first type of glass 4 is shorter than that of the second type of glass 5 , and the length of the second type of glass 5 is shorter than that of the third type of glass 6 .

[0056] The setting of the first positioning group, the second positioning group and the third positioning group can meet the placement and positioning requirements of glass of different sizes without replacing components, which facilitates use and ensures production efficiency. The first positioning group, the second positioning group and the third positioning group have adjustment capabilities, which further improves their adaptability and reduces the cost of use.

[0057] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
