[0003] Mass production includes large-scale continuous production and small-batch production. During mass production, different feeding devices are required for materials of different specifications and even shapes. For sheet-like materials, negative pressure adsorption is generally used. Therefore, when changing materials, the corresponding feeding device also needs to be replaced. It is impossible to automatically adjust the adsorption range according to different materials, which affects the efficiency of automatic feeding.

[0004] In addition, the currently used fixed material handling device cannot perform offset compensation during the automatic feeding process, which affects the processing accuracy. Summary of the Invention

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example: Figures 1-6 As shown, the present invention provides a paper mounting machine technical solution with automatic feeding function.

[0026] The paper mounting machine includes a conveyor 1 and a feeding device 2. The feed end and the side of the conveyor 1 are respectively equipped with feeding devices 3, and the conveyor 1 is equipped with a forming device 4. The pick-and-place device 2 includes a positioning component 22 and a sensing component 23, which are connected together. The adjustment component 22 is connected to the conveyor 1, and the adjustment component 22 adjusts the adsorption range of the cardboard through the sensing component 23.

[0027] Multiple cardboard sheets are bonded together using a laminating machine, suitable for different specifications. Conveyor 1 serves as the main power source for conveying the cardboard. The cardboard is placed on the feeding device 3, and automatically fed by the pick-and-place device 2. Feeding devices 3 are installed along the feeding direction of conveyor 1 at the feed end and on the side. One is installed at the feed end, and the number on the side is adjusted as needed, for example, two on the side. The pick-and-place device 2 at the feed end of conveyor 1 lifts the cardboard and places it onto conveyor 1. Conveyor 1 then moves the cardboard forward. The pick-and-place device 2 on the side automatically adjusts the adsorption range according to the size of the cardboard, improving applicability to multiple product categories. The sensing component 23 drives the positioning component 22 to move, allowing the positioning component 22 to adapt to the shape of the cardboard and adjust the adsorption range according to the size of the cardboard, completing self-positioning adsorption.

[0028] Furthermore, the pick-and-place device 2 also includes a drive assembly 21; The adjusting assembly 22 comprises a mounting frame 221, a shaft tube 223, and an adjusting electromagnet 226. The lower end of the shaft tube 223 is provided with a suction nozzle 222, and the shaft tube 223 is sleeved with a baffle plate 224. The adjusting electromagnet 226 is connected with the mounting frame 221. The driving assembly 21 is connected with the conveyor 1 and the mounting frame 221, and the baffle plate 224 is slidingly connected with the mounting frame 221. When the paperboard is retracted, the opposite ends of the adjusting electromagnet 226 and the baffle plate 224 are opposite magnetic poles, and the friction between the suction nozzle 222 and the paperboard is greater than the magnetic pole attraction between the adjusting electromagnet 226 and the baffle plate 224.

[0029] The driving assembly 21 is the main driving power source and mainly generates linear displacement. The driving assembly 21 is mounted on the conveyor 1 and drives the mounting frame 221 to move, so that the paperboard on the side edge feeding device 3 is moved to the conveyor 1, and automatic splicing and bonding are facilitated. Each shaft tube 223 is provided with a suction nozzle 222 below, which is connected with a negative pressure source to generate negative pressure suction. The adjusting electromagnet 226 is mounted on the mounting frame 221 and is provided with a power supply to supply power to the adjusting electromagnet 226. In the initial state, the suction nozzle 222 is located at the circumferential position of the mounting frame 221. Through the magnetic pole attraction, the baffle plate 224 drives the shaft tube 223 to move towards the adjusting electromagnet 226. When the suction nozzle 222 contacts the paperboard, friction is generated. When the bottom of the suction nozzle 222 completely contacts the paperboard, the bottom of the suction nozzle 222 is sealed by the paperboard, the suction reaches the maximum, and the friction between the suction nozzle 222 and the paperboard is positively correlated with the suction, that is, the greater the suction, the greater the friction. When the friction reaches the maximum, it is greater than the magnetic pole attraction between the adjusting electromagnet 226 and the baffle plate 224, that is, the suction nozzle 222 no longer slides, so as to automatically adjust according to the size of the paperboard. After the side edge paperboard is adsorbed, the paperboard is placed on the conveyor 1 by the driving assembly 21, and is spliced and bonded with the paperboard fed from the conveying end, thereby improving the forming efficiency.

[0030] Further, the mounting frame 221 is circumferentially provided with a plurality of sliding grooves 2211, and the upper side of each sliding groove 2211 is provided with a negative pressure flow channel 2212. The plurality of sliding grooves 2211 are slidingly connected with the adjacent baffle plates 224, and the suction nozzle 222 is connected with the negative pressure flow channel 2212 through the shaft tube 223.

[0031] The slide groove 2211 is arranged to guide the sliding of the blocking plate 224. The negative pressure flow channel 2212 is arranged above the slide groove 2211 and is connected to the negative pressure source. The slide groove 2211 is arranged with a downward opening. The blocking plate 224 seals the slide groove 2211. During the sliding of the blocking plate 224, the suction nozzles 222 are connected to the negative pressure flow channel 2212 through the shaft tube 223, so as to provide negative pressure suction force. The direction of the negative pressure suction force is perpendicular to the sliding direction of the blocking plate 224. In the initial state, the suction range formed by all the suction nozzles 222 is the largest. The suction nozzles 222 are linearly moved and automatically stop moving when the suction nozzles 222 are in full contact with the paperboard, so as to adjust the suction range.

[0032] Further, the adjusting assembly 22 further comprises a middle shaft 225, and the lower end of the middle shaft 225 is provided with the suction nozzles 222. The middle shaft 225 is rotationally connected to the negative pressure flow channel 2212. The suction nozzles 222 below the middle shaft 225 are connected to the negative pressure flow channel 2212 through the through holes in the middle shaft 225.

[0033] The suction nozzles 222 at the lower end of the shaft tube 223 are arranged in the circumferential direction of the mounting frame 221. The middle shaft 225 is arranged at the central part of the mounting frame 221. The lower end of the middle shaft 225 is also provided with the suction nozzles. The through holes are arranged in the middle shaft 225. The middle shaft 225 is inserted into the negative pressure flow channel 2212 above, so that the suction nozzles 222 can be connected to the negative pressure flow channel 2212 through the through holes in the middle shaft 225. The middle shaft 225 can rotate in the negative pressure flow channel 2212 through the rotation arrangement.

[0034] Further, the sensing assembly 23 comprises coils 232. Two groups of coils 232 are arranged close to one side of the paperboard alignment edge. The mounting frame 221 is provided with a plurality of sensing cavities 2213 close to the paperboard splicing edge. The sensing cavities 2213 are provided with air valves 233. The blocking plate 224 is provided with magnetic columns 231. One end of the magnetic column 231 is inserted into the coil 232. The coil 232 is arranged in the sensing cavity 2213. The difference between the currents of the two groups of coils 232 is used as the control current of the adjusting electromagnet 226.

[0035] During the process of automatically adjusting the adsorption range according to the size of the paperboard, the magnetic column 231 moves with the blocking plate 224, the coil 232 moves in a cutting magnetic field line, and an induced current is generated. Two groups of coils 232 are arranged on the aligned edges of the paperboard. If the initial position of the paperboard meets the standard positioning, the currents of the two circuits in which the two coils 232 are located are equal. If the initial position of the paperboard is tilted and misaligned, a difference between the currents of the two circuits is generated. According to the size of the difference, the current size of the positioning electromagnet 226 is adjusted. The air valve 233 is an electromagnetic valve. During the adjustment, the air valve 233 is turned on. For example, the positioning electromagnet 226 with a smaller current value is increased in input current, the suction nozzle 222 is moved to the side close to the positioning electromagnet 226, the positioning electromagnet 226 with a larger current value is inputted with a reverse current, the suction nozzle 222 is moved to the side away from the positioning electromagnet 226, and thus displacement compensation is automatically performed to correct the paperboard.

[0036] Further, the driving assembly 21 comprises a horizontal module 211, and a vertical module 212 is arranged at a movable end of the horizontal module 211. A fixed end of the horizontal module 211 is connected with the conveyor 1, and a movable end of the vertical module 212 is connected with the positioning assembly 22.

[0037] The horizontal module 211 and the vertical module 212 are respectively used for providing horizontal and vertical linear displacement, and can adopt a conventional screw module form. The vertical module 212 is used for driving the suction nozzle 222 to move downward, after adjustment is completed, driving the paperboard to move upward, bringing the side paperboard to the conveyor 1 through the horizontal module 211, and then driving the paperboard to move downward for splicing.

[0038] As an optimization, the feeding device 3 comprises a feeding frame 31, and a lifting machine 32 is arranged on the feeding frame 31. The lifting machine 32 is arranged on the feeding frame 31 and is used for driving the paperboard to lift, thereby improving the feeding efficiency.

[0039] As an optimization, the forming device 4 comprises a guide assembly 41, and the guide assembly 41 comprises a guide frame 411 and a plurality of rotationally connected guide wheels 412 arranged on the guide frame 411. The guide frame 411 is fixedly connected with the conveyor 1. The guide frame 411 is installed on the conveyor 1, and the guide wheels 412 press the paperboard on the belt of the conveyor 1, thereby ensuring the conveying accuracy.

[0040] As an optimization, the forming device 4 further comprises a downward pressing cylinder 42 and a glue spraying head 44. The glue spraying head 44 is arranged at an output end and faces the paperboard to be bonded. The downward pressing cylinder 42 is provided with a hot pressing piece 43 at an output end, and the downward pressing cylinder 42 is connected with the conveyor 1. The glue spraying head 44 is arranged to spray glue on the paperboard fed into the feeding end of the conveyor 1. After the side paperboard is lowered, the hot pressing piece 43 is driven by the downward pressing cylinder 42 to move downward, thereby pressing and splicing the two side paperboards.

[0041] The working principle of the present application: the side taking and delivering device 2 automatically adjusts the adsorption range according to the size of the paperboard, improving the multi-category applicability. The induction assembly 23 is used to drive the positioning assembly 22 to move, so that the positioning assembly 22 adapts to the shape of the paperboard, adjusts the adsorption range according to the size of the paperboard, and completes self-positioning adsorption; in the initial state, the suction nozzle 222 is located at the circumferential position of the mounting frame 221, and through the magnetic pole suction force, the plug plate 224 drives the shaft pipe 223 to move towards the direction close to the positioning electromagnet 226; when the suction nozzle 222 and the paperboard contact, friction is generated, and when the bottom of the suction nozzle 222 and the paperboard are in complete contact, the bottom of the suction nozzle 222 is sealed by the paperboard, the suction force reaches the maximum, and the friction force of the suction nozzle 222 and the paperboard is positively correlated with the suction force, that is, the greater the suction force, the greater the friction force; when the friction force reaches the maximum, it is greater than the magnetic pole suction force of the positioning electromagnet 226 and the plug plate 224, that is, the suction nozzle 222 no longer slides, thereby automatically adjusting according to the size of the paperboard; the direction of the negative pressure suction force is perpendicular to the sliding direction of the plug plate 224, and in the initial state, the adsorption range formed by all the suction nozzles 222 is the largest; through the linear movement of the suction nozzle 222 and the automatic stop moving when in complete contact with the paperboard, the adsorption range is adjusted; two groups of coils 232 are arranged on the aligned edge of the paperboard; if the initial position of the paperboard meets the standard positioning, the currents of the two circuits in which the two coils 232 are located are equal; if the initial position of the paperboard is inclined and misaligned, the two circuit currents produce a difference; according to the difference, the current input to the positioning electromagnet 226 is adjusted; the air valve 233 adopts an electromagnetic valve; when adjusting, the air valve 233 is turned on, for example, the positioning electromagnet 226 with a smaller current value, the input current is increased, driving the suction nozzle 222 to move towards the side close to the positioning electromagnet 226, and the positioning electromagnet 226 with a larger current value, the reverse current is input, driving the suction nozzle 222 to move away from the side away from the positioning electromagnet 226, thereby automatically compensating for the displacement and correcting the paperboard.
