Description

Technical Field

[0001] The utility model relates to the technical field of mesh sheet feeders, in particular to a mesh sheet feeder. Background Art

[0002] At present, the mesh sheet feeding machine adopts a single axis calibration method for feeding and conveying.

[0029] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Example

[0031] like Figure 1-5 As shown, the utility model proposes a mesh sheet feeding machine, including an equipment frame 100, which adopts a square tube as an overall frame, and a sealing plate is arranged on the overall frame as a partition, such as Figure 2 As shown, a door panel is provided on the cover plate of the equipment rack 100 to facilitate the maintenance of various components located in the equipment rack 100. The equipment rack 100 is fixed with a loading and lifting mechanism for storing mesh sheets for initial axial positioning, a transverse feeding mechanism for taking mesh sheets in the lifting and lifting mechanism and sending them to the next positioning link, and a sheet positioning mechanism for performing secondary positioning on the mesh sheets transferred by the transverse feeding mechanism. A detection unit for inspecting the mesh sheets to achieve single-sheet transfer is provided on the mesh sheet moving path of the transverse feeding mechanism. In this way, after the mesh sheets are initially positioned and stored by the loading and lifting mechanism, the mesh sheets are stacked, and the mesh sheets stacked on the loading and lifting mechanism can be taken out by the transverse feeding mechanism. During the taking process, the number of mesh sheets taken out is measured by the detection unit to determine that the number taken out is a single sheet. The extra mesh sheets will be peeled off, and then the single-piece mesh sheets will be transferred to the sheet positioning mechanism for secondary positioning, thereby completing the loading work.

[0032] The loading and lifting mechanism includes a platform 200 fixed on the equipment frame 100, and a mobile platform 201 is arranged on the upper side of the platform 200, which is adjusted by a transverse cylinder 202 fixed on the platform 200, and a pair of travel switches located on both sides of the mobile platform 201 are arranged on the platform 200, which can touch each other when the mobile platform 201 moves to determine the maximum or minimum movement distance. The mobile platform 201 in this embodiment specifically includes a track fixed on the platform 200, a slider is slidably arranged on the track, and a loading plate is fixed on the slider. Two groups of adjustable calibration parts 203 for positioning the peripheral axis of the mesh sheet are arranged on the upper side of the movable platform 201. The adjustable calibration part 203 includes a clamp fixed on the movable platform 201 for positioning and clamping by radially narrowing, and a clamping rod extending upward is fixed on the clamping end of the clamp; in order to stabilize the axis determination of the mesh sheet, the clamping rod is a round rod to ensure that it can be accurately retracted by the clamp, and the clamp is a three-jaw clamp in the present embodiment, and the existing technology is adopted, so no further explanation is given for this; the adjustable calibration part 203 is movably sleeved with an adjustable carrier 204 fixed on the movable platform 201 for receiving the mesh sheets positioned and stacked by the adjustable calibration part 203, and a path groove for the movement of the clamping rod is opened on the adjustable carrier 204; the path groove enables the adjustable calibration part 203 to move stably. The adjustable object carrier 204 includes a guide column fixed on the movable platform 201, a carrier plate is movably sleeved on the guide column, and a path groove is set on the carrier plate. A lifting module 205 is fixed on the lower side of the platform 200, which is located in the equipment frame 100 and automatically pushes a certain distance when the number of mesh sheets stacked on the adjustable object carrier 204 is quantitatively reduced. A group of through-beam sensors for detecting the mesh sheets stacked on the adjustable object carrier 204 are set on the upper side of the platform 200. The lifting module 205 controls the lifting distance through the through-beam sensors; the single lifting distance of the lifting module 205 can be set according to actual needs.

[0033] The transverse feeding mechanism includes a crossbeam 300 that spans the material loading and lifting mechanism and is fixed to its platform 200. A transverse moving module 301 is fixed on the crossbeam 300. A material grabbing cylinder 302 that moves back and forth between the material loading and lifting mechanism and the sheet positioning mechanism is fixed on the moving end of the transverse moving module 301. An adsorption module 303 for picking up the mesh sheet is fixed on the output end of the material grabbing cylinder 302. The main function of the transverse moving module 301 in this embodiment is to drive the transverse moving module 301 to move back and forth. In order to adopt the existing technology, it will not be described in detail here; the material grabbing cylinder 302 fixed on the moving end of the transverse moving module 301 can perform telescopic movement, and is connected to the external air supply equipment and control equipment for motion control.

[0034] Optionally, the adsorption module 303 is provided with a diffuse reflection sensor 206 which activates an alarm when it moves to the upper side of the adjustable object carrier 204 to detect that there is no material on the adjustable object carrier 204; when the diffuse reflection sensor 206 moves to the upper side of the adjustable object carrier 204 to start the adsorption module 303 to take the mesh sheet, it will detect the mesh sheet on the adjustable object carrier 204, and automatically generate an alarm action after the mesh sheet is taken; it should be noted that the detection method of the diffuse reflection sensor 206 on the adsorption module 303 adopts a direct judgment whether the adsorption module 303 is adsorbed to the mesh sheet to judge whether there is a mesh sheet on the adjustable object carrier 204. The adsorption module 303 includes a structural frame fixed on the output end of the material grabbing cylinder 302, a material pushing cylinder fixed on the structural frame, a magnetic suction piece fixed on the output end of the material pushing cylinder, a blocking rod fixed at the bottom of the structural frame, and an opening provided on the magnetic suction piece for the blocking rod to pass through; the material pushing cylinder is in an extended state during the process of moving the mesh sheet, and when unloading, the material pushing cylinder is contracted so that the blocking rod abuts against the mesh sheet, thereby causing the mesh sheet to fall off. When the adsorption module 303 moves to the upper side of the adjustable object carrier 204 to take the mesh sheet, the material grabbing cylinder 302 will be controlled to perform an initial shaking action at the same time to reduce the possibility of overlapping adsorption of the adsorption module 303.

[0035] The sheet positioning mechanism includes a double-layer frame 400 fixed on the equipment frame 100. The double-layer frame 400 is a double-layer structure design, including two rectangular plates, and the two rectangular plates are connected by a column; a cylinder group positioning module 401 is fixed on the double-layer frame 400 for positioning the inner aperture axis of a single mesh sheet that is transversely moved to the double-layer frame 400, and a synchronous belt positioning module 402 is fixed on the double-layer frame 400 for positioning the outer peripheral axis of a single mesh sheet on the double-layer frame 400. The cylinder group positioning module 401 includes a moving cylinder fixed on the double-layer frame 400, and a centering piece is fixed on the output end of the moving cylinder. The synchronous belt positioning module 402 includes a servo motor fixed on the double-layer frame 400, and a fixed shaft is provided on the double-layer frame 400. The output end of the servo motor and the fixed shaft are driven by a synchronous belt. Two symmetrically arranged positioning pieces are fixed on the synchronous belt. The two positioning pieces are distributed on both sides of the cylinder group positioning module 401 and move in opposite directions. When the synchronous belt positioning module 402 rotates, the positioning parts are brought close to each other to achieve peripheral axis positioning; and the centering piece on the cylinder group positioning module 401 is used to determine the position. The centering piece is composed of three round rods with pointed ends, which makes it easier to position the axis.

[0036] The detection unit includes a material box 500 fixed on the equipment frame 100, and a detection stacking sensor a501 fixed on the adsorption module 303. The material box 500 is fixed with a detection stacking sensor b502 set on the movement path of the detection stacking sensor a501, so that when the detection stacking sensor a501 moves to overlap the detection stacking sensor b502, the mesh sheet taken from the adsorption module 303 is judged and fed back to the material grabbing cylinder 302 to realize the movement action, so that the overlapping mesh sheet falls to the material box 500. The material box 500 is used to store the overlapped mesh sheets that are shaken off, which can be used for subsequent manual recovery and replenished to the adjustable object carrier 204 for reuse; the detection stacking sensor a501 and the detection stacking sensor b502 detect the thickness of the mesh sheet adsorbed on the adsorption module 303 when overlapping to judge the quantity; and then the material grabbing cylinder 302 increases the shaking action to make the overlapping mesh sheet adsorbed on the adsorption module 303 fall off.

[0037] In this embodiment, the working principle of the present solution when it is actually put into use is as follows: when the equipment is stopped, the lifting module 205 is at the lowest position, and the operator begins to stack the sheets on the upper side of the adjustable carrier 204, and then after the two sets of adjustable carriers 204 are filled, the adjustable calibration member 203 is adjusted to a reasonable position; so that the stacked sheets are calibrated by the axis, and the equipment is started to work, which refers to all the components in the device that need to be in working state, and then the equipment will be in running state, at this time the transverse movement module 301 is in working state, and will be moved to the adjustable carrier 204 through the grabbing cylinder 302 and pick up the sheet through the adsorption module 303, and the grabbing cylinder 302 will be automatically started after the sheet is taken. The overlapping sheets are shaken twice for the first time, and then during the transfer process, it is necessary to determine whether there are overlapping sheets on the adsorption module 303 through the detection of the stacking sensor a501 and the stacking sensor b502. If there are, it will continue to shake and increase the force. At the same time, after falling off, it will continue to move forward and be sent to the upper side of the double-layer rack 400. Since the adsorption module 303 moves to the corresponding position of the double-layer rack 400, the unloading action of the adsorption module 303 will be automatically started, and then the sheet will fall off onto the double-layer rack 400, and then the cylinder group positioning module 401 will be started to position the inner ring, and the synchronous belt positioning module 402 will be used to position the outer ring. After completing the secondary positioning, it will be grabbed by an external robot to the lower moving station;

[0038] The sheets in the loading and lifting mechanism are continuously fed by the transverse feeding mechanism, which reduces the sheets on the adjustable carrier 204, and then the incident sensor lights up, and then the lifting module 205 starts to rise. When there is no sheet on one group of adjustable carriers 204, the transverse cylinder 202 will be automatically started to switch positions, so that the other group of adjustable carriers 204 can continue to feed materials. After the alarm is generated, the operator will continue to stack the consumed sheets of the adjustable carriers 204, and the operation will be cyclical.

[0039] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
