Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a feeding tray feeding component. Background Art

[0002] AOI equipment is a high-precision and high-efficiency inspection technology that uses light sources and cameras to perform non-contact automated inspections on printed circuit boards (PCBs) or other electronic components. AOI equipment has the function of fully inspecting the appearance defects of glass. Before use, the glass is cleaned and dried before entering the AOI full inspection equipment. However, in the existing technology, the tray containing multiple glasses is mainly placed on the feeding belt of the AOI full inspection equipment manually. This method of manually taking the tray can easily cause bumps and cause the glass to be scrapped. In addition, it is more dependent on manpower and has high labor costs.

[0003] To this end, the applicant provides a tray loading device, which includes a conveyor belt and a lifting device. The tray is placed on the conveyor belt and transferred to the lifting device, and then the lifting device lifts the tray upward to the feeding belt of the AOI full inspection equipment. However, since the conveyor belt and the lifting device are not equipped with a mechanism to position or guide the tray, the initial position of the tray when placed on the conveyor belt is not accurate, and the tray is prone to deviation during the transmission process. In addition, the tray is not guided during the lifting process, which can also cause the tray to deviate, and the tray is prone to collision, resulting in the scrapping of the glass. Utility Model Content

[0004] The utility model aims to provide a material tray loading assembly to solve the problem that the prior art does not guide and position the material tray, which causes the material tray to easily deviate and cause collisions, resulting in the scrapping of glass.

[0005] In order to solve the above problems, the utility model provides the following technical solutions:

[0006] A material tray loading assembly comprises a frame, the frame is provided with a conveyor belt and a lifting mechanism, the lifting mechanism comprises a vertical slide rail and a lifting seat slidably connected to the slide rail, the slide rail is provided with a cylinder for driving the lifting seat to slide up and down, and the lifting seat is symmetrically fixed with a lifting plate for lifting the material tray upward; the frame is symmetrically fixed with baffles located on opposite sides of the conveyor belt, the baffles include an inverted L-shaped guide angle, and the frame is also symmetrically fixed with guide rods close to the slide rail, and the distance between the baffles on both sides and the distance between the guide rods on both sides are equal to the width of the material tray.

[0007] The working principle and beneficial effects of the utility model:

[0008] In this solution, the inverted L-shaped guide angles on both sides fit the corners on both sides of the tray, and the tray is placed on the conveyor belt along the inverted L-shaped guide angles on both sides. The inverted L-shaped guide angles on both sides position the tray so that the tray is accurately placed on the conveyor belt. Then the conveyor belt is started to transfer the tray to the lifting plate. The tray is located between the guide rods on both sides. The lifting seat is driven upward by the cylinder to slide. The sliding seat lifts the tray upward through the lifting plate. The guide rods on both sides abut against the tray, thereby preventing the tray from running off during the rising process.

[0009] This solution uses the guide angles on both sides to accurately locate the initial position of the material tray. The initial position of the material tray placed on the conveyor belt is accurate, the material tray does not deviate during transportation, and the guide rods on both sides abut against the material tray during the lifting process, so the material tray does not deviate during the lifting process, thereby effectively avoiding collisions between the material trays and causing the glass to be scrapped.

[0010] Preferably, the baffle is provided with a notch, which makes it easier for workers to place the tray on the conveyor belt, and the operation is more convenient, which is conducive to aligning the tray with the guide angle.

[0011] Optimally, the number of guide rods on each side of the frame is 2, and the 2 guide rods on this side are respectively located on opposite sides of the tray. This optimization solution can effectively limit the tray during lifting, and the tray will not deviate during lifting.

[0012] Optimally, the frame is also fixed with a tray-in-place limiting column. When the tray is lifted to a certain height, the tray contacts the tray-in-place limiting column, so that the tray will not be lifted further.

[0013] Optimally, the conveyor belt is driven by a motor, and the frame is provided with a tray arrival sensor and a conveyor belt deceleration sensor connected to the motor electrical signal. When the tray passes through the conveyor belt deceleration sensor during the transmission process, the conveyor belt decelerates, and when the tray reaches the tray arrival sensor, the conveyor belt stops transmitting.

[0014] Optimally, the cylinder electrical signal is connected to a lifting position sensor. When the lifting plate moves downward and passes the lifting position sensor, the cylinder stops working, thereby ensuring that the lifting plate is located under the material tray and lifted upward. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 The utility model is a structural schematic diagram of a material tray loading assembly. DETAILED DESCRIPTION

[0016] The following is further described in detail through specific implementation methods:

[0017] The reference numerals in the drawings of the specification include: guide angle 1, baffle 2, conveyor belt 3, material tray 4, notch 5, slide rail 6, cylinder 7, lifting seat 8, lifting plate 9, guide rod 10.

[0018] In the following statements, directional words such as "left", "right", "up", and "down" are all based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the directions while keeping the relative positions unchanged, it will not affect the implementation of the plan.

[0019] Embodiment: A tray loading assembly, such as Figure 1 As shown, the machine comprises a frame, the frame is provided with a conveyor belt 3 and a lifting mechanism, and the conveyor belt 3 is specifically a belt conveyor. The lifting mechanism comprises a vertical slide rail 6 and a lifting seat 8 vertically slidably connected to the slide rail 6, the slide rail 6 is fixedly connected to the frame, the slide rail 6 is fixedly provided with a cylinder 7 for driving the lifting seat 8 to slide up and down, and the lifting seat 8 is symmetrically fixed with a lifting plate 9 for lifting the material tray 4 upward.

[0020] The frame is symmetrically fixed with baffles 2 located on opposite sides of the conveyor belt 3, the baffles 2 include an inverted L-shaped guide angle 1, and the baffles 2 are provided with a notch 5. The frame is also symmetrically fixed with guide rods 10, and the distance between the baffles 2 on both sides and the distance between the guide rods 10 on both sides are equal to the width of the material tray 4.

[0021] In this solution, the inverted L-shaped guide angles 1 on both sides fit with the corners on both sides of the tray 4, and the tray 4 is placed on the conveyor belt 3 along the inverted L-shaped guide angles 1 on both sides through the notch 5. The inverted L-shaped guide angles 1 on both sides position the tray 4 so that the tray 4 is accurately placed on the conveyor belt 3. Then the conveyor belt 3 is started to transfer the tray 4 to the lifting plate 9. The tray 4 is located between the guide rods 10 on both sides. The lifting seat 8 is driven upward by the cylinder 7 to slide. The sliding seat lifts the tray 4 upward through the lifting plate 9. The guide rods 10 on both sides abut against the tray 4, thereby forming a limit for the tray 4, thereby preventing the tray 4 from running off during the rising process.
