Description

Technical Field

[0001] The utility model relates to the technical field of secondary positioning of trays, in particular to a secondary lifting and positioning device for trays. Background Technique

[0002] Due to the design structure of the stacking (piling up materials) mechanism on the production line, for the sheet materials placed on the positioning tray, the inserting rod cannot be directly used to position the sheet materials during stacking; therefore, after stacking and packing, it is necessary to use a crane to lift the sheet materials to finely adjust their positions, and at least 4 people need to cooperate with each other to meet the positioning of the tray inserting rod. Therefore, in order to improve the positioning efficiency of the tray and the sheet materials, a lifting and positioning device is usually used.

[0003] As the automation level of the stamping line of the vehicle manufacturer increases, the robotic arm for transporting the sheet materials gradually replaces the traditional manual transportation. The requirements for the stacking neatness of the sheet materials, the transportation safety guarantee, the rapid in-line detection of production, the positioning system, etc. are continuously increasing. To meet the production requirements, the blanking positioning tray for automotive sheets is currently widely used in major vehicle manufacturers. The adjustment of the sheet materials needs to be carried out online operation, and it takes about 10 minutes to adjust to the accurate position, which interrupts the production rhythm and affects the continuous production efficiency. During the fine adjustment operation process, 4 operators stand under the crane hook or lifting tool for a long time and cannot maintain a safe distance, there is a risk of lifting injury. The operators need to hold the sheet materials by hand to finely adjust the positions. If the sheet materials are large in size, they also need to walk back and forth to observe the positioning situation, there is a risk of scratching fingers and squeezing the legs. During the adjustment process, the sheet materials need to be repeatedly lifted and lowered, which causes damage to the crane equipment. If it is not placed stably and topples over, it may cause casualties. At the same time, there are many operators participating in the operation, and there is a risk of human-machine interaction operation injury.

[0004] Therefore, we propose a secondary lifting and positioning device for trays to facilitate the solution of the problems raised above. Content of the Utility Model

To meet the production requirements, the blanking positioning tray for automotive sheets is currently widely used in major automotive main engine factories. The adjustment of the sheet material needs to be carried out online operation, and it takes about 10 minutes to adjust to the accurate position, which interrupts the production rhythm and affects the continuous production efficiency. During the micro-adjustment operation process, 4 operators stand under the crane hook or lifting tool for a long time and cannot maintain a safe distance, there is a risk of lifting injury. The operator has to hold the sheet material by hand to make micro-adjustments to the position. If the sheet material is large in size, the operator also needs to walk back and forth to observe the positioning situation, there is a risk of scratching fingers and squeezing legs. During the adjustment process, the sheet material needs to be repeatedly lifted and lowered, which causes damage to the crane equipment; if it is not placed stably and topples over, it may cause casualties.

Detailed implementation manners

[0035] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0036] Embodiment 1: Please refer to Figures 1-6 , due to the improvement of the automation level of the stamping line in the vehicle factory, the robotic arm is gradually replacing the traditional manual handling of the blank sheets. The requirements for the stacking neatness of the blank sheets, the transportation safety guarantee, the rapid production centering detection, the positioning system, etc. are continuously increasing. To meet the production requirements, the automotive sheet blanking positioning pallet is currently widely used in major vehicle factories. The sheet adjustment needs to be carried out online operation, and it takes about 10 minutes to adjust to the accurate position, which interrupts the production rhythm and affects the continuous production efficiency. During the micro-adjustment operation process, 4 operators stand under the crane hook or spreader for a long time and cannot maintain a safe distance, there is a risk of lifting injury. The operator needs to hold the sheet with his hand to make micro-adjustment of the position. If the sheet size is large, he also needs to walk back and forth to observe the positioning situation, there is a risk of scratching fingers and leg extrusion. During the adjustment process, the sheet needs to be repeatedly lifted and lowered, which causes damage to the crane equipment. If it is not placed stably and topples over, it may cause casualties. At the same time, there are many personnel participating in the operation, there is a risk of man-machine interaction operation injury. To solve this technical problem, the following technical content is disclosed in this embodiment, including a central support 1, a first support frame 2 is arranged on the left side of the central support 1, and a second support frame 3 is arranged on the right side of the central support 1; two connecting guide rails 4 are fixedly connected to the upper end of the central support 1, and a moving slider 5 is arranged on the connecting guide rail 4. The moving slider 5 is fixed to the lower end of the adjusting frame 6, and a bearing seat 7 is installed on the adjusting frame 6. Two guide rollers 8 are connected inside the bearing seat 7 through bearings, and a support cross bar 9 is arranged between the two guide rollers 8. A branch rod 10 is fixedly connected to the side of the end of the support cross bar 9; the first support frame 2 and the second support frame 3 are symmetrically arranged about the longitudinal central axis of the central support 1. The inner wall of the moving slider 5 and the inner wall of the connecting guide rail 4 are mutually attached, and the moving slider 5 can move on the connecting guide rail 4. The two guide rollers 8 inside the bearing seat 7 are symmetrically arranged about the transverse central axis of the bearing seat 7, and the two guide rollers 8 are respectively attached to the upper and lower surfaces of the support cross bar 9. The cross section of the branch rod 10 is set as a "U" shaped structure, and the branch rods 10 are distributed on both sides of the end of the support cross bar 9.

[0037] When secondary positioning of the sheet material and the tray is required, push the adjusting frame 6 on the central support 1. After the adjusting frame 6 is pushed, the moving slider 5 at its lower end moves on the connecting guide rail 4, so as to realize the longitudinal adjustment of the adjusting frame 6, and thus make an adaptive adjustment according to the size of the positioned sheet material. Then, use a crane to lift the tray between the first support frame 2 and the central support 1 or between the second support frame 3 and the central support 1. Here, taking the case where the tray is lifted between the second support frame 3 and the central support 1 as an example, after the tray is lifted between the second support frame 3 and the central support 1, pull the support cross bar 9 on the adjusting frame 6, so that the support cross bar 9 moves horizontally under the support of the upper and lower guide rollers 8 until the end of the support cross bar 9 overlaps on the second support frame 3. At this time, the crane lifts the sheet material and places it on the support cross bar 9, and adjusts the position of the tray below the support cross bar 9 to the position required by the inserting rod. If the tray needs to be replaced, a tray transport cart can be used for operation. And a branch rod 10 is arranged on the side of the end of the support cross bar 9. Through the arrangement of the branch rod 10, it can be avoided that the support cross bar 9 moves out of the guide roller 8 during the horizontal movement.

The outer wall of the first pin 12 and the inner wall of the first jack 11 are mutually attached, and the contact surface between the lower end of the first pin 12 and the support cross bar 9 is set as a rough surface. A plurality of second jacks 14 are evenly distributed at equal intervals on the support plate 13, and the inner wall of the second jack 14 and the outer wall of the second pin 15 are mutually attached.

[0039] After the position of the adjusting frame 6 is adjusted, insert the second pin 15 into the second jack 14 on the support plate 13. Through the two second pins 15 on the side of the adjusting frame 6, the position of the adjusting frame 6 after longitudinal movement is fixed. After the end of the support cross bar 9 overlaps on the support frame, by inserting the first pin 12 into the inside of the first jack 11, the lower end of the first pin 12 is mutually attached and contacted with the surface of the support cross bar 9, so as to fix the position of the support cross bar 9 after horizontal adjustment.
