TECHNICAL FIELD

[0001] The utility model relates to a feeding equipment technical field, especially in a sheet material detection equipment's double position feeding device. BACKGROUND

[0002] In the automatic production line, sheet material usually adopts the scheme of mechanical hand cooperation negative pressure suction head to carry and feed, before the sheet material is carried by the mechanical hand, usually multiple sheets are arranged in the form of stack, the sheet is continuously jacked by the jacking mechanism to facilitate the mechanical hand adsorption to realize the feeding. However, the sheet feeding mechanism of single station needs to stop after the sheet is taken to replenish the sheet, so the efficiency is low. UTILITY MODEL CONTENT

[0003] In view of the deficiencies of the prior art, the main purpose of the utility model is to provide a double position sheet feeding mechanism which can realize uninterrupted feeding and improve the production efficiency of the equipment without stopping for feeding.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a double position feeding device of sheet material detection equipment, including bottom plate, a pair of slide rails are arranged on the bottom plate, a first feeding unit and a second feeding unit are arranged on the pair of slide rails, a material jacking unit is arranged in the middle of the first feeding unit and the second feeding unit; the first feeding unit and the second feeding unit all include a sliding block slidingly arranged on the pair of slide rails, a loading plate is arranged on the sliding block, a stretching cylinder capable of pulling the loading plate to reciprocatingly slide along the pair of slide rails is arranged on the bottom plate, a plurality of guide rods are arranged on the loading plate, a supporting plate capable of bearing sheet material is inserted on the plurality of guide rods, a through hole is arranged on the loading plate at the supporting plate; the material jacking unit includes a lead screw stepper motor fixedly arranged on the bottom plate, four fixed seats arranged in the form of square are arranged around the lead screw stepper motor on the bottom plate, an optical shaft is inserted in each fixed seat, the top of the four optical shafts is connected with a jacking plate, and the jacking plate and the four optical shafts can be jacked by the lead screw of the lead screw stepper motor.

[0005] Preferably, the top of the four optical shafts protrudes the jacking plate, and the bottom of the supporting plate is provided with four positioning holes corresponding to the four optical shafts.

[0006] Preferably, a wear-resistant collar is arranged in the positioning hole.

[0007] Preferably, a limiting groove for placing the supporting plate is arranged on the loading plate.

[0008] This invention has the following advantages over existing technologies: First, the stacked sheets are sequentially passed through several guide rods and placed onto a support plate. Then, the telescopic cylinder of the first or second feeding unit drives the loading plate to slide along a pair of slide rails to the top feeding unit. Next, the lead screw stepper motor starts, and the lead screw of the stepper motor rises to lift the lifting plate. The four optical shafts on the lifting plate are also lifted, and the lifting plate drives the support plate to rise. The support plate then moves the sheets upward along the guide rods, facilitating material removal by the robotic arm. When the sheets from one feeding unit are removed, the lead screw stepper motor drives the lead screw to descend, and the telescopic cylinder drives the support plate to retract. Then, another feeding unit starts working, moving the support plate to the top feeding unit. At this time, the prepared sheets are manually placed onto the support plate that has just been removed, and this process is repeated. This solution does not require stopping the machine for feeding; the dual-station setup enables uninterrupted feeding, improving the production efficiency of the equipment.

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1As shown, a double-station feeding device of a sheet detection equipment includes a bottom plate 1, a pair of slide rails 2 is arranged on the bottom plate 1, a first feeding unit and a second feeding unit are arranged on the pair of slide rails 2, and a lifting unit is arranged between the first feeding unit and the second feeding unit; the first feeding unit and the second feeding unit each include a sliding block 3 slidingly arranged on the pair of slide rails 2, a loading plate 4 is arranged on the sliding block 3, a stretching cylinder 5 is arranged on the bottom plate 1 and capable of pulling the loading plate 4 to reciprocally slide along the pair of slide rails 2, a plurality of guide rods 6 are arranged on the loading plate 4, a supporting plate 7 capable of bearing the sheet is inserted on the guide rods 6, and a through hole 8 is arranged on the loading plate 4 at the supporting plate 7; the lifting unit includes a lead screw stepper motor 9 fixedly arranged on the bottom plate 1, four fixed seats 10 arranged in a square are arranged around the lead screw stepper motor 9 on the bottom plate 1, an optical shaft 11 is inserted in each fixed seat 10, and a lifting plate 12 is connected to the top of the four optical shafts 11, and the lead screw of the lead screw stepper motor 9 can lift the lifting plate 12 together with the four optical shafts 11.

[0016] The working principle of the double-station feeding device of the sheet detection equipment is that the stacked sheets are sequentially arranged on the supporting plate 7 after being sequentially inserted through the plurality of guide rods 6, then the stretching cylinder of the first feeding unit or the second feeding unit drives the loading plate 4 to slide to the lifting unit along the pair of slide rails 2, then the lead screw stepper motor 9 is started, the lead screw of the lead screw stepper motor 9 is lifted to lift the lifting plate 12, the four optical shafts 11 on the lifting plate 12 are also lifted, the lifting plate 12 drives the supporting plate 7 to be lifted, the supporting plate 7 drives the sheets to move upward along the guide rods 6, and the mechanical hand is convenient to take the sheets. When the sheets of one feeding unit are taken, the lead screw of the lead screw stepper motor 9 is lowered, the stretching cylinder drives the supporting plate to retreat, then the other feeding unit starts to work, the supporting plate 7 is moved to the lifting unit, at this time, the prepared sheets are manually placed on the supporting plate 7 from which the sheets have just been taken, and the above steps are repeated.
