[0058] The positioning base plate mechanism comprises a positioning base plate 8, on which a guide mechanism 5 and a guide slide block are mounted, on which a front positioning mechanism 6 and a rear positioning mechanism 7 are mounted, and below the positioning base plate 8 a rack is mounted.

[0059] In addition, if Figure 6 As shown, the guide mechanism 5 includes a guide base plate 22 , a guide seat 23 is mounted on the guide base plate 22 , and a guide mold 24 is mounted on the guide seat 23 .

[0060] In this embodiment, if Figure 7As shown, the front positioning mechanism 6 includes a front positioning base plate 25, on which are respectively mounted a front positioning guide rail slider 26, a front positioning opening and closing cylinder seat 29, a front positioning anti-deflection cylinder seat 31 and a front positioning motor seat 34; the front positioning guide rail slider 26 is mounted with a front positioning opening and closing seat 27, on which is mounted a front positioning opening and closing mold 28; the front positioning opening and closing cylinder seat 29 is mounted with a front positioning opening and closing cylinder 30, on which is mounted a fisheye joint; the front positioning anti-deflection cylinder seat 31 is mounted with a front positioning anti-deflection cylinder 32, on which is mounted a front positioning anti-deflection block 33; the front positioning motor seat 34 is mounted with a front positioning drive motor 35, on which is mounted a front positioning gear 36.

[0061] Similarly, in Figure 8 In the figure, the rear positioning mechanism 7 includes a rear positioning base plate 37, on which are respectively mounted a rear positioning guide rail slider 38, a rear positioning opening and closing cylinder seat 41, a rear positioning anti-deflection cylinder seat 44 and a rear positioning motor seat 48; the rear positioning guide rail slider 38 is mounted with a rear positioning opening and closing seat 39, on which are mounted a rear positioning opening and closing mold 40 and a rear positioning pressing cylinder 46, on which are mounted a rear positioning pressing sheet 47, on which are mounted a rear positioning opening and closing cylinder seat 41, on which are mounted a rear positioning opening and closing cylinder 42, on which are mounted a fisheye joint; on the rear positioning anti-deflection cylinder seat 44, a rear positioning anti-deflection cylinder 43 is mounted, on which are mounted a rear positioning anti-deflection block 45, on which are mounted a rear positioning drive motor 49, on which are mounted a rear positioning gear 50.

[0062] Specifically, the operation process of the door seal rubber sleeve auxiliary positioning mold insertion mechanism is divided into two stages:

[0063] In the first section, the front positioning mechanism 6 and the rear positioning mechanism 7 in the rubber sleeve positioning mechanism 2 are driven by the driving motor, and at the same time merged with the guide mechanism 5 until they are in contact, and are ready for mold entry. At this time, the two door seal rubber sleeves are simultaneously transmitted from the two belts 12 in the rubber sleeve conveying mechanism 3 to the preset position (the preset position is set by the photoelectric switch), and when the rubber sleeves reach the preset position, the rubber sleeve conveying mechanism 3 stops. At this time, the three material-dispensing cylinders 17 in the rubber sleeve mold entry mechanism 1 act simultaneously, and the two rubber sleeves are pulled to the left and right to the designated position (the designated position is preset by the positioning strip 15) respectively, so as to guide the mold entry. Then, the pusher module 21 pushes forward, driving the pusher connecting rod 19 and the pusher block 20 to push forward at a uniform speed. After running a distance, they contact with the material-dispensing cylinder 17 and move forward together until they contact the rubber sleeve. At this time, the forward mold entry distance controlled by the servo motor is equal to the total length after the front positioning mechanism 6, the rear positioning mechanism 7, and the guide mechanism 5 are combined, and the rubber sleeve is completed.

[0064] In the second stage, after the rubber sleeve is completely put into the mold, the rear positioning pressing cylinder 46 in the rear positioning mechanism 7 is activated, driving the rear positioning pressing piece 47 to press down the rubber sleeve, and then the rear positioning drive motor 49 drives the rear positioning gear 50 and the rack to transmit to each other, and after the rear positioning mechanism 7 is moved to the preset position (the preset position is half the distance from the center of the positioning base plate to the current rubber sleeve length), the rear positioning pressing piece 47 rises and releases. In this process, in order to prevent the front positioning mechanism 6 and the rear positioning mechanism 7 from colliding, the front positioning mechanism 6 lags behind the rear positioning mechanism 7 for two seconds, and starts to move to the preset position in the same direction together (the preset position is the total length of the rubber sleeve from the rear positioning mechanism). At this time, the front positioning mechanism 6 and the rear positioning mechanism 7 respectively position the front and rear end faces of the rubber sleeve, and are symmetrical at both ends of the center of the positioning base plate, waiting for the robot to grab. When the robot moves down to the preset position (the preset position is specifically set according to the height of the cross section of the rubber sleeve), the two rear positioning opening and closing cylinders 42 in the rear positioning mechanism 7 move to open the rear positioning opening and closing mold 40, so that the rubber sleeve can be grasped and removed by the robot. After the rubber sleeve is removed, the front positioning mechanism 6 and the rear positioning mechanism 7 are merged with the guide mechanism 5 again until they are in contact and enter the mold-ready state, and then the rubber sleeve conveying mechanism 3 is re-operated to convey the rubber sleeve, and the mold entry and positioning are repeated in this way.

[0065] During the whole process, the front positioning anti-deviation cylinder 32 in the front positioning mechanism 6 drives the front positioning anti-deviation block 33, and the left and right sides are closed symmetrically to prevent the rubber sleeve from shifting or even falling off during the entire mobile positioning process. The same components in the rear positioning mechanism 7 have the same functions and are not repeated here.

[0066] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0067] Specifically, in the technical solution of the present invention, the power mechanism of the rubber sleeve molding mechanism is a synchronous belt module, and the rubber sleeve positioning power mechanism is a servo motor plus a gear rack combination. In view of the large number of standard drive products for realizing linear motion adjustment (such as linear motors, synchronous belts, gear racks, screw rods, etc.), this patent states that only by changing the drive mode to imitate the solution of the present invention, it also falls within the protection scope of the present invention.

[0068] After the present invention is positioned in the mold, it is mainly used for automatic door seal welding. The solution of using the present invention for other processes also belongs to the protection scope of the present invention.

[0069] The present invention is a dual-station positioning mold-entry method, and the solution to realize the functions of the present invention by increasing or decreasing the number of stations also belongs to the protection scope of the present invention.

[0070] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0071] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
