Description

Technical Field

[0001] The utility model relates to the technical field of material transmission, in particular to a material transmission line. Background Art

[0002] Liquid crystal display (LCD) is a display device widely used in electronic products. It has the advantages of small size, light weight, low power consumption, and good display effect. In the production process of LCD, LCD panels need to be processed through multiple processes, such as cutting, laminating, and testing. In order to improve production efficiency and quality, it is usually necessary to transport and position LCD panels quickly, accurately, and stably between different processes.

[0003] The commonly used method of conveying LCD panels is conveyor belt transportation. The LCD panel is placed on the conveyor belt, and the smooth movement of the conveyor belt drives the movement of the LCD panel. The LCD panel is accurately conveyed to a fixed position through the induction device and the blocking bar (after the induction device senses the LCD panel, the induction device controls the conveyor belt to stop running, so that the conveyor belt stops, and the blocking bar is located at a fixed position, so that the LCD panel stays at a fixed position under the blocking effect of the blocking bar). The advantage of this method is that the friction force of the belt on the LCD panel is small, which can reduce the wear of the LCD panel. However, when the LCD panels on the conveyor belt are dense, the conveyor belt will move forward a short distance due to inertia during the process of being controlled to stop by the induction device, which can easily cause the rear LCD panel to continue to move forward, collide and squeeze with the LCD panel blocked by the blocking bar, causing the LCD panel to arch, resulting in the inability of the induction device to sense the existence of the LCD panel at the fixed position, and then the conveyor belt continues to move, further causing the LCD panels to pile up and squeeze at the fixed position, causing the LCD panels to be severely damaged due to squeezing, collision and falling. Utility Model Content

[0004] The utility model aims to provide a material conveying line, which is used to solve the technical problem that the traditional conveyor belt structure has overlapping plates which causes a large amount of material damage.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: to provide a material conveying line, the material conveying line comprising:

[0006] Bracket;

[0007] A conveyor belt, wherein the conveyor belt is arranged on the bracket;

[0008] Side plates, the side plates are fixed on the bracket and arranged on both sides of the conveyor belt, and the side plates are higher than the conveying surface of the conveyor belt;

[0009] A blocking bar, the blocking bar is arranged on the side plate at the end of the conveyor belt, the blocking bar is arranged perpendicular to the conveying direction of the conveyor belt, and the bottom of the blocking bar is in close contact with the conveying surface of the conveyor belt, and the blocking surface of the blocking bar is provided with a pressure sensor device, and the pressure sensor device is electrically connected to the power system of the conveyor belt;

[0010] The sensing device is arranged on the side plate and is located on one side of the blocking surface of the blocking bar. The sensing device is electrically connected to the power system of the conveyor belt.

[0011] In one embodiment, the barrier strip comprises:

[0012] A mounting plate, both ends of which are fixed to the side plates;

[0013] The blocking plate is fixed to the lower side of the mounting plate, and the bottom of the blocking plate is in close contact with the conveying surface of the conveyor belt.

[0014] In one embodiment, the surface of the blocking plate is wrapped with an insulating elastic material layer.

[0015] In one embodiment, the blocking plate includes a main body and an elastic blocking portion, a groove is provided between the main body and the elastic blocking portion, and the pressure sensing device is provided in the groove.

[0018] One or more of the above technical solutions in the embodiments of the present utility model have at least the following technical effects or advantages:

[0019] In the material conveying line provided by the embodiment of the utility model, when the material (LCD panel) is transported to the preset loading position via the conveyor belt, the sensing device (infrared sensor) senses the presence of material at the preset loading position, and then controls the conveyor belt to stop running, and at the same time, the blocking bar blocks the material from continuing to move, so that the material can be accurately transported to the preset loading position for subsequent loading (when the material at the preset loading position is taken away, the sensing device does not sense the presence of material at the position, and the conveyor belt continues to move). When the materials on the conveyor belt are placed densely, causing the materials to bulge so that the sensing device cannot sense the materials normally, at this time, due to the increase of materials at the preset loading position, the pressure on the blocking surface of the blocking bar increases. When the pressure sensing device detects that the pressure on the blocking surface of the blocking bar exceeds the normal range (the pressure given by a piece of material), the pressure sensing device controls the conveyor belt to stop running, thereby avoiding the accumulation of a large amount of materials at the preset loading position and causing batch damage to the materials.

[0029] See also Figure 1 to Figure 2 The embodiment of the present application provides a material 6 conveying line, including a bracket 1, a sensing device 5, a side plate 3, a blocking bar 4, and a conveyor belt 2. The conveyor belt 2 is arranged on the bracket 1; the side plate 3 is fixed on the bracket 1, and the side plate 3 is arranged on both sides of the conveyor belt 2, and the side plate 3 is higher than the conveying surface of the conveyor belt 2; the blocking bar 4 is arranged on the side plate 3 at the end of the conveyor belt 2, and the blocking bar 4 is arranged perpendicular to the conveying direction of the conveyor belt 2, and the bottom of the blocking bar 4 is close to the conveying surface of the conveyor belt 2, and the blocking surface of the blocking bar 4 is provided with a pressure sensor 43, and the pressure sensor 43 is electrically connected to the power system of the conveyor belt 2; the sensing device 5 is arranged on the side plate 3, and the sensing device 5 is located on the blocking surface side of the blocking bar 4, and the sensing device 5 is electrically connected to the power system of the conveyor belt 2.

[0030] In the material 6 conveying line provided in this embodiment, when the material 6 is transported to the preset loading position via the conveyor belt 2, the sensing device 5 senses the presence of the material 6 at the preset loading position, and then controls the conveyor belt 2 to stop running, and the blocking bar 4 blocks the material 6 from continuing to move, so that the material 6 can be accurately transported to the preset loading position for subsequent loading (when the material 6 at the preset loading position is taken away, the sensing device 5 does not sense the presence of the material 6 at the position, and the conveyor belt 2 continues to move). When the material 6 on the conveyor belt 2 is placed densely, causing the material 6 to bulge so that the sensing device 5 cannot normally sense the material 6, at this time, the pressure on the blocking surface of the blocking bar 4 increases due to the increase of the material 6 at the preset loading position. When the pressure sensing device 43 detects that the pressure on the blocking surface of the blocking bar 4 exceeds the normal range (the pressure given by a piece of material 6), the pressure sensing device 43 controls the conveyor belt 2 to stop running, thereby avoiding the accumulation of a large amount of material 6 at the preset loading position and causing batch damage to the material 6.

[0031] In one embodiment, the blocking bar 4 includes a mounting plate 41 and a blocking plate 42. Both ends of the mounting plate 41 are fixed to the side plate 3; the blocking plate 42 is fixed to the lower side of the mounting plate 41, the bottom of the blocking plate 42 is in close contact with the conveying surface of the conveyor belt 2, and the distance between the bottom of the blocking plate 42 and the conveying surface of the conveyor belt 2 is less than the thickness of the material 6.

[0033] In one embodiment, the surface of the blocking plate 42 is wrapped with an insulating elastic material layer, which may be a rubber layer or a plastic layer. By providing the insulating elastic material layer, when the blocking plate 42 blocks the material 6, the impact on the material 6 can be reduced, thereby preventing the material 6 from being broken due to the blocking of the blocking plate 42. The method is particularly suitable for transmitting brittle and fragile materials 6 such as LCD panels.

[0034] In one embodiment, the blocking plate 42 includes a main body 421 and an elastic blocking portion 422, a groove is provided between the main body 421 and the elastic blocking portion 422, and a pressure sensing device 43 is provided in the groove. By providing the elastic blocking portion 422, when the blocking plate 42 blocks the material 6, the elastic blocking portion 422 can reduce the impact force on the material 6 by its own elastic deformation to protect the material 6. In addition, the pressure sensing device 43 in the groove can monitor the pressure on the blocking plate 42 in real time to determine whether the material 6 is stacked.
