[0002] Prepreg, also known as PP sheet, is the raw material for making multilayer printed circuit boards. Trays (hereinafter referred to as trays) have recessed surfaces for the prepreg. After each tray is loaded with a prepreg, the trays are stacked and ready for use. When a prepreg is needed, it is removed from the tray one by one. Each time a prepreg is removed, the tray must be removed to allow the next prepreg to be exposed.

[0003] In the existing prepreg loading process, the prepreg is removed by a robot and placed on a processing station. The tray is then manually removed and placed in an empty tray storage area. This loading and unloading method relies entirely on manual labor, resulting in low loading efficiency and high labor intensity. Utility Model Content

DETAILED DESCRIPTION

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] like Figures 1 to 8As shown, the present invention discloses a tray-based board feeder, which includes a frame A; a loading assembly is disposed inside the frame A; the loading assembly is composed of a tray temporary storage assembly B and a tray lifting mechanism D disposed below the tray temporary storage assembly B; a conveying robot C is disposed inside the frame A for removing prepregs from the tray lifting mechanism D;

[0035] A guide wheel A1 is provided at the bottom of the frame A for guiding and positioning the trolley;

[0036] The conveying robot C can absorb and fix the prepreg in the tray and then transfer it to the required workstation for processing. It is essentially the same as the existing technology, so it will not be described in detail.

[0037] The tray lifting mechanism D is loaded with stacked trays, each containing prepregs. The conveying robot C removes the top prepreg and places it on a designated workstation for processing. The tray temporary storage component B removes the trays after the prepregs are removed and stores them on the tray temporary storage component B. The tray temporary storage component B then stacks the empty trays on the bottom of the previously stacked empty trays on the tray temporary storage component B.

[0038] In this structure, the automatic stacking and storage of empty trays can be realized, which reduces the labor intensity of stacking and storing empty trays when prepregs are loaded, and improves the efficiency of tray storage.

[0039] As a preferred embodiment of the present invention, the tray temporary storage assembly B includes a tray temporary storage frame B2, two tray temporary storage lifting assemblies B1 symmetrically arranged on both sides of the tray temporary storage frame B2, and two tray limiting assemblies B3 symmetrically arranged on both sides of the tray temporary frame B2; the two tray limiting assemblies B3 are used to support the empty trays collected by the tray temporary storage lifting assembly B1;

[0040] The tray temporary storage lifting component B1 takes out the top empty tray on the tray lifting mechanism D and transports it upward until the empty tray on the tray temporary storage lifting component B1 is pressed against the bottom of the empty tray supported by the two tray limit components B3. The tray limit component B3 retracts and the tray temporary storage lifting component B1 continues to rise. When all the empty trays are lifted upward to the point where the bottom empty tray is higher than the tray limit component B3, the tray limit component B3 extends outward and extends under the bottom empty tray, supporting all the empty trays through the tray limit component B3. Then the tray temporary storage lifting component B1 moves downward to separate from the empty tray on the tray limiting component B3, and then takes out the empty tray from the tray lifting mechanism D for stacking, and repeats the above steps; until the tray temporary storage component B is full of material and there is no tray on the tray lifting mechanism D below, the tray limiting component B3 retracts, and the tray temporary storage lifting component B1 transports all empty trays to the tray lifting mechanism D, and finally the material cart takes out the stacked empty trays from the tray lifting mechanism D, and the trays are stacked and temporarily stored by the tray temporary storage component B, and finally taken out from the tray lifting mechanism D by the material cart.

[0041] As a preferred embodiment of the present invention, the tray temporary storage lifting assembly B1 includes a connecting plate B106 and a first lifting seat B108; the connecting plate B106 is connected to the tray temporary storage frame B2; a lifting linear module B107 is connected between the connecting plate B106 and the first lifting seat B108; a plurality of first extension cylinders B102 are connected to the first lifting seat B108; the piston rod end of the first extension cylinder B102 is connected to the first clamping plate B101;

Before the first pallet B101 descends to align with the bottom of the topmost tray of the tray lifting mechanism D, the first pallet B101 retracts to a position where it does not interfere with the tray. When the first pallet B101 descends to align with the bottom of the topmost tray of the tray lifting mechanism D, the first extension cylinder B102 can drive the first pallet B101 to extend and insert it into the bottom of the topmost tray of the tray lifting mechanism D. After the lifting linear module B107 is activated, it lifts the empty tray upward.

[0043] As a preferred embodiment of the present invention, a lifting slider B105 is fixed on the connecting plate B106; a lifting straight guide rail B103 slidably connected to the lifting slider B105 is fixed on the tray temporary storage frame B2; a first lifting cylinder B104 is connected between the tray temporary storage frame B2 and the connecting plate B106;

[0044] When the tray storage assembly B is full, all empty trays need to be transported from the tray storage assembly B to the tray lifting mechanism D below. After the tray limit assembly B3 retracts, all empty trays are placed on the first pallet B101. The first lifting cylinder B104 enables long-distance transport of the first pallet B101 and transports the empty trays to the tray lifting mechanism D.

[0045] As a preferred embodiment of the present invention, the tray limiting assembly B3 is composed of a second extending cylinder B301 and a second clamping plate B302; the two ends of the second extending cylinder B301 are respectively fixed on the tray temporary storage frame B2 and the second clamping plate B302; the second extending cylinder B301 can drive the second clamping plate B302 to extend or retract.

[0046] As a preferred embodiment of the present invention, the tray lifting mechanism D includes two lifting mechanism modules D3 and a synchronization component for driving the lifting mechanism modules D3 to move synchronously up and down;

[0047] The lifting mechanism module D3 includes a lower fixed base D3010 fixed on the frame A, a second lifting base D304 slidably connected to the lower fixed base D3010, and a lifting linear module for driving the second lifting base D304 to perform lifting motion;

[0048] The second lifting seat D304 is provided with multiple support blocks D304a, which support the tray on both sides through two tray lifting components; the lifting linear module drives the support blocks on the second lifting seat D304 to rise, and lifts the tray carrying the prepreg.

[0049] As a preferred embodiment of the present invention, the lifting linear module includes a screw rod D308 rotatably connected to the lower fixed base D3010 and a screw nut D309 threadedly connected to the screw rod D308; the screw nut D309 is fixed to the second lifting base D304; the first reduction gearbox D305 and the second reduction gearbox D306 are fixed to the lower fixed base D3010; the screw rod D308 is connected to the output end of the second reduction gearbox D306; the input end of the second reduction gearbox D306 is connected to the output end of the first reduction gearbox D305;

[0050] The synchronization assembly includes a motor D1 and a synchronization shaft D2 connected to the output end of the motor D1; the two ends of the synchronization shaft D2 are respectively connected to the input ends of the two first reduction gearboxes D305;

[0051] A guide sleeve is fixed on the second lifting seat D304; a guide column is provided on the lower fixed seat D3010 and is slidably connected to the guide sleeve; the number of screw rods D308 and the number of second reduction gearboxes D306 are both two; a transmission shaft D307 is connected between the two second reduction gearboxes D306;

[0052] After the motor D1 is started, it drives the synchronous shaft D2 to rotate. The synchronous shaft D2 drives the screw rods D308 on both sides to rotate through the first reduction gearbox D305 and the first reduction gearbox D305 on both sides. The second lifting seats D304 on both sides are lifted and lowered synchronously to lift the tray carrying the prepreg, so that the material picking height of the conveying robot C and the tray temporary storage component B is consistent each time.

[0053] As a preferred embodiment of the present invention, a floating centering unit D303 is fixed on each of the support blocks D304a; a positioning cylinder D301 is arranged on the second lifting seat D304; and a push plate D302 is fixed on the positioning cylinder D301;

[0054] The floating centering unit D303 is essentially the same as the existing technology, so it will not be described in detail here. The bottommost tray is supported by multiple floating centering units D303. Positioning cylinders D301 on either side drive push plates D302 to align the tray with the tray lift mechanism D, securing it in place. The floating centering unit D303's contact with the bottom of the tray allows for frictionless movement, preventing frictional debris from the displacement between the tray and support block D304a when the positioning cylinders D301 align the tray.

[0055] As a preferred embodiment of the present invention, a static elimination rod D3011 is fixed on the lower fixing seat D3010; the static elimination rod D3011 is essentially the same as the prior art and therefore will not be described in detail, and is used to eliminate static electricity on the product.
