Description

Technical Field

[0001] This utility model relates to the field of automatic material feeding technology in automobile processing, specifically a material tray lifting machine. Background Technology

[0002] In the production and processing of four-door cars, different types of edge trim strips, also known as door sill strips, are installed on the four doors (front left, front right, rear left, rear right) to increase protection. During installation, a robotic arm usually picks up the edge trim strips from a tray placed in a predetermined position. However, the tray is usually only placed at the picking position of the robotic arm for feeding. The replacement of trays for the four different types of edge trim strips is mostly done manually, which is not safe enough and cannot meet the needs of large-volume edge trim strips in continuous production processes. There is an urgent need for a fast and efficient automatic edge trim strip supply equipment to stably and safely supply materials.

[0003] Based on this, the present invention designs a material tray lifting machine to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a material tray lifting machine to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material tray elevator, comprising: two fixedly connected frames; each of the two frames is provided with a lifting mechanism and a monitoring mechanism on its outer wall;

[0006] The lifting mechanism includes a lead screw rotatably connected to the outer wall of the frame, a lead screw sleeve block threaded to the outer wall of the lead screw, a bracket fixed to one end of the lead screw sleeve block, two seat plates fixed to the top of the bracket, a protective strip tray set on the top of the seat plate, and a servo motor drivenly connected to one end of the conveying lead screw.

[0007] The monitoring mechanism includes a connecting frame at the top of the frame, and a first positioning sensor and a second positioning sensor respectively fixed to one end of the connecting frame;

[0008] The outer wall of the edge guard strip tray is provided with a monitoring slot for use with the second positioning sensor.

[0009] Preferably, a plurality of first limiting plates and second limiting plates are fixed to the outer wall of the frame, the plurality of first limiting plates being symmetrically arranged with each other, and the plurality of second limiting plates being symmetrically arranged with each other.

[0010] Preferably, the first limiting plate and the second limiting plate face each other and cooperate with the frame to constrain the vertical displacement of the edge guard strip material tray during the lifting process.

[0011] Preferably, a slide rail is fixed to the outer wall of the frame, and a slider is fixed to the outer wall of the bracket, with one end of the slider slidably connected to the track of the slide rail.

[0012] Preferably, the height of the first positioning sensor is lower than that of the second positioning sensor.

[0013] Preferably, the servo motor is fixedly installed at the bottom of the frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] Firstly, the two frames divide the space into two sections. Inside the frames, two types of edge trim trays are stacked on two seats of the brackets. Then, the assembly operation is carried out by the lifting mechanism in conjunction with the robotic arm. This allows for fast, stable, efficient and safe automatic feeding of four different types of edge trim trays to meet the demand for large-volume edge trims in continuous production processes.

[0016] Secondly, during the lifting process, the first positioning sensor can be used to monitor whether the edge strip tray is in place, and the second positioning sensor can be used in conjunction with the monitoring slot of the edge strip tray to monitor whether all the edge strips loaded in the tray have been removed, thus assisting in more precise tray alternation operations.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a material tray elevator, comprising: two fixedly connected frame frames 1; each of the two frame frames 1 is provided with a lifting mechanism and a monitoring mechanism on its outer wall;

[0028] The lifting mechanism includes a lead screw 2 rotatably connected to the outer wall of the frame 1, a lead screw sleeve 3 threadedly connected to the outer wall of the lead screw 2, a bracket 4 fixed to one end of the lead screw sleeve 3, two seat plates 5 fixed to the top of the bracket 4, a guard strip tray 11 set on the top of the seat plate 5, and a servo motor 8 drivenly connected to one end of the conveying lead screw 2.

[0029] The monitoring mechanism includes a connecting frame 13 at the top of the frame 1, and a first positioning sensor 14 and a second positioning sensor 15 respectively fixed to one end of the connecting frame 13;

[0030] The outer wall of the edge guard strip tray 11 is provided with a monitoring slot 12 that works in conjunction with the second positioning sensor 15;

[0031] Two frames 1 are fixed to each other, and each lifts the stacked edge trim material trays 11 through a lifting mechanism. The replacement of edge trim material trays 11 is monitored by a monitoring mechanism. In the lifting mechanism, the servo motor 8 controls the screw 2 to rotate forward or backward. After rotation, it can simultaneously drive the screw sleeve block 3, the bracket 4, and the two seat plates 5 of the bracket 4 to move up or down within the frame 1 to assist in the lifting operation. In the monitoring mechanism, the first position sensor 14 and the second position sensor 15 are both capacitive. They monitor the position of the edge trim material trays 11 and the condition of the edge trim through the changing capacitance effect.

[0032] More preferably, a plurality of first limiting plates 9 and second limiting plates 10 are fixed to the outer wall of the frame 1, the plurality of first limiting plates 9 are symmetrically arranged with each other, and the plurality of second limiting plates are symmetrically arranged with each other;

[0033] Multiple first limiting plates 9 and second limiting plates 10 of the frame 1 are arranged around the two seat plates 5 of the bracket 4, and a lifting and moving space is formed around the seat plates 5 through the symmetrical first limiting plates 9 and second limiting plates 10.

[0034] More preferably, the first limiting plate 9 and the second limiting plate 10 face each other and cooperate with the frame 1 to constrain the vertical displacement of the edge guard strip 11 during the lifting process;

[0035] The first limiting plate 9 and the second limiting plate 10, together with the frame 1, form a space whose dimensions match the size of the edge guard strip tray 11, that is, match the outer contour of the tray 11, ensuring that the tray 11 is stably centered during the lifting process and avoiding shaking or collision.

[0036] More preferably, a slide rail 6 is fixed to the outer wall of the frame 1, and a slider 7 is fixed to the outer wall of the bracket 4, with one end of the slider 7 slidably connected to the track of the slide rail 6;

[0037] The cooperation of slide rail 6 and slider 7 further enhances the stability of frame 1's vertical movement, making it less prone to deviation.

[0038] More preferably, the height of the first positioning sensor 14 is lower than that of the second positioning sensor 15;

[0039] The first positioning sensor 14 and the second positioning sensor 15 have a height difference, which facilitates the monitoring of the edge guard strip tray 11 and the edge guard strip respectively.

[0040] More preferably, the servo motor 8 is fixedly mounted on the bottom of the frame 1;

[0041] Servo motor 8 is fixedly installed on frame 1 to perform stable transmission operation.

[0042] One specific application of this embodiment is as follows: two frames 1 are divided into two sections, and two types of edge trim trays 11 are stacked in the frame 1 through two seats 5 of the bracket 4, while four types of edge trim are supplied at the same time. The assembly operation is carried out in conjunction with the robotic arm. After the top edge trim tray 11 is depleted, it is removed by the robotic arm. At the same time, the lead screw 2 is rotated by the servo motor 8, and the bracket 4, seat 5 and stacked edge trim trays 11 are driven by the lead screw sleeve 3 to move the bracket 4, seat 5 and stacked edge trim trays 11 stably upward between the frame 1, the first limit plate 9 and the second limit plate 10, to the material picking height position. During the lifting, the first positioning sensor 14 of the connecting frame 13 is used to monitor whether the edge trim tray 11 is in place, and the second positioning sensor 15 is used in conjunction with the monitoring slot 12 of the edge trim tray 11 to monitor whether the edge trim loaded in the edge trim tray 11 has been depleted, so as to assist in more precise alternation of trays 11.
