2. After the edge of the plate positioning module b is found successfully, the plate positioning module b adjusts the transverse position of the plate, so that the front end of the plate is aligned with the tail end of the plate in the front row. Then the plate d is pressed on the material supporting arm c4 by the constant pressure mechanism c5, on one hand, the plate can move forwards along with the forward movement of the sliding frame c2, and the plate is prevented from moving in the moving process; on the other hand, in the cutting and welding process of the plate, the plate is still pressed by the constant pressure mechanism, so that the plate is prevented from deviating.

3. The plate cutting module e reciprocates along the width direction of the plate, namely, the laser moves transversely to cut and level the foremost end of the plate, and the auxiliary supporting mechanism c7 supports the plate d to prevent the front end part of the plate from bending downwards under the action of gravity, so that the plate is cut to form a flat front edge of the plate again, the flat front edge of the plate is convenient to be butted with the previous plate during the next welding, and a better welding effect is achieved.

4. After laser cutting is completed, the traction mechanism c3 continues to pull the plate to move towards the welding device, the front end of the plate is always supported by the auxiliary supporting mechanism in the transferring process, the front end portion of the plate is prevented from bending downwards under the action of gravity, the front end portion of the plate is guaranteed to be always kept in a horizontally unfolded state in the transferring process, the auxiliary supporting mechanism c7 can automatically retreat and avoid when being very close to the welding device, the auxiliary supporting mechanism is prevented from colliding with the welding device in the process that the sliding frame continues to move forwards, meanwhile, the sliding frame continues to move forwards, the plate is smoothly and horizontally conveyed onto the welding device, and therefore the shell clamping phenomenon when the front end of the plate is connected with the welding device is avoided.

Specifically, referring to fig. 9 and 10, the auxiliary supporting mechanism c7 includes a material supporting bracket c71 installed on the side surface of the material supporting arm, a guiding seat c74 installed on the material supporting bracket, a guiding rod c75 transversely inserted into the guiding seat, a supporting bar c72 installed above the material supporting bracket, and an avoiding cylinder c73 for driving the supporting bar to move back and forth.

In practical application, the number of the auxiliary supporting mechanisms c7 is the same as that of the material supporting arms c4, and each material supporting arm c4 is correspondingly provided with one auxiliary supporting mechanism c 7; the auxiliary supporting mechanism c7 is installed on the side of the material supporting arm c4, the flat bar part c721 of the supporting bar c72 is flush with the top surface of the material supporting arm c4, the avoiding cylinder c73 can drive the supporting bar c72 to move in the front-back direction (i.e. the direction close to/away from the welding device), and in the initial state, the flat bar part c721 extends forwards, i.e. the front end part of the flat bar part c721 is closer to the welding device than the front end part of the material supporting arm c 4. When the device works, the plate is firstly transited to the material supporting arm c4 from the positioning device until the plate is completely pressed on the supporting strip c72 and the material supporting arm c4, and at the moment, the front end part of the plate is supported by the supporting strip c72, as shown in fig. 5, so that the front end part of the plate is prevented from bending downwards under the action of gravity, and the front end part of the plate is ensured to be always kept in a horizontally unfolded state in the transferring process; then, the constant pressure mechanism c5 presses the sheet material on the material supporting arm c4, and finally, the traction mechanism c3 drives the carriage c2 to make the sheet material advance towards the welding device.

In order to control the carrying bar c72 to avoid, as shown in fig. 4 and 6, a first travel switch c81, a second travel switch c82, a third travel switch c83 and a fourth travel switch c84 are arranged on the frame a in sequence from back to front; the first travel switch c81, the second travel switch c82, the third travel switch c83 and the fourth travel switch c84 are all electrically connected with a control system, a front trigger piece c85 and a rear trigger piece c86 which are used for triggering the travel switches are arranged on the carriage c2, the front trigger piece c85 is installed on the front end face of the carriage c2, and the rear trigger piece c86 is installed on the rear end face of the carriage c 2. In the initial state, the rear trigger piece c86 triggers the first travel switch c81, which indicates that the carriage c2 is located at the initial position; under the driving of a traction mechanism c3, the sliding frame c2 moves forward towards the direction of the plate cutting module, when a front trigger piece c85 triggers a second travel switch c82, the plate is indicated to move to a leveling cutting area, the second travel switch c82 feeds back a signal to a control system, the control system controls the traction mechanism to stop acting, but at the moment, the supporting strip c72 is in an extending state, and the plate cutting module performs cutting leveling on the front end of the plate; then the front trigger piece c85 triggers the third travel switch c83 to indicate that the supporting strip c72 is very close to the welding device, the third travel switch c83 feeds back a signal to the control system, the control system controls the avoidance cylinder c73 to enable the avoidance cylinder c73 to drive the supporting strip c72 to retreat and avoid, the supporting strip c72 is prevented from colliding with the welding device in the process that the sliding frame c2 continues to advance, meanwhile, the sliding frame c2 continues to advance, the plate is smoothly and horizontally fed onto the welding device, so that the problem of shell clamping when the front end of the plate is connected with the welding device is avoided, the front trigger piece triggers the fourth travel switch c84 to indicate that the plate is transferred in place, the welding device welds the head of the plate and the tail of the downstream plate, and the constant pressure mechanism c5 loosens the plate after welding is completed; then the traction mechanism c3 drives the carriage c2 to move backwards and reset, although the rear trigger piece c86 triggers the third travel switch c83, the supporting bar c72 is in a retreating and retracting state at the moment and cannot move, then the rear trigger piece c86 triggers the second travel switch c82, and the second travel switch c82 feeds back a signal to the control system, so that the avoiding cylinder c73 drives the supporting bar c72 to extend forwards again; when the rear trigger piece c86 triggers the first travel switch c81, the carriage c2 is reset to the initial position.

In this embodiment, the guide seat c74 is provided with two linear bearing seats, and the guide rod c75 is a cylindrical shaft rod and transversely penetrates through the two guide seats c 74. The two linear bearing seats can share the downward pressure of the guide rod, the guide rod and the support bar are better loaded, and the guide rod and the linear bearing seats are matched to slide, so that the guide rod is ensured to slide smoothly in the transverse direction.

Preferably, the material supporting arm c4 is formed by processing a square tube, so that the material supporting arm is convenient to purchase and process and low in manufacturing cost. The top surfaces of the material supporting arms form a smooth bearing surface, and the plate materials are flattened on the bearing surfaces of the plurality of material supporting arms; the bottom of the front end part of the material supporting arm c4 is provided with a notch c41, so that the whole material supporting arm is in a shape of

And a plurality of mounting holes are formed in the side surface of the material supporting arm c4, and a worker can put screws into the material supporting arm through the notch c41 and assemble the material supporting arm with the screws in a matched mode through the mounting holes.

In order to ensure smooth and smooth movement of the carriage c2, a guide rail a4 extending in the front-rear direction is provided on each first square tube a1, and the bottom of the carriage c2 is slidably connected to the guide rail a4 through a slider a 5.

Furthermore, two groups of limit components c9 for limiting the forward and backward travel of the carriage c2 are arranged on the frame; each set of the spacing components c9 comprises a spacing seat c91, a hydraulic buffer c92 arranged on the spacing seat c91 and a spacing adjusting screw c93 arranged on the spacing seat c 91. When the sliding frame c2 is in place, the sliding frame c2 is firstly contacted with the hydraulic buffer c92, the hydraulic buffer c92 absorbs the moving inertia impact, the sliding frame c2 is decelerated and then abuts against the end part of the limit adjusting screw c93, the final stop position of the sliding frame c2 can be adjusted by screwing the limit adjusting screw c93, and the effect of adjusting the moving distance of the sheet material and the initial position of the sliding frame c2 is achieved.

In the embodiment, the traction mechanism c3 drives the carriage to move back and forth by using a transmission mode of a synchronous belt, and of course, the carriage may be driven to move by using a transmission mode of a chain transmission, a belt transmission or a linear module.

Furthermore, the carriage c2 is provided with an ejection roller c61 located at the upstream of the material supporting arm and a jacking driving mechanism for driving the ejection roller to move up and down. The ejection roller c61 is along transversely extending, jacking actuating mechanism includes two liftout cylinder c62 that set up, and two liftout cylinder c 62's output connects the both ends of ejection roller c61 respectively, and the roller end of ejection roller c61 passes through locking screw to be fixed on liftout cylinder c62, and liftout cylinder c62 passes through erection support to be fixed on balladeur train c 2. Note that, in the initial state of the topping roller c61, the height of the topping roller c61 is flush with the height of the carrier arm c 4. After the material ejecting cylinder c62 drives the material ejecting roller c61 to complete the up-and-down reciprocating motion within a set time, the material ejecting cylinder c62 enables the material ejecting roller c61 to keep an ejecting state, namely the height of the material ejecting roller c61 is higher than that of the material supporting arm c4, through the arrangement, the height of a plate positioned between the plate positioning module b and the material supporting arm c4 can be improved to the maximum extent, and the phenomenon that the plate bends downwards due to gravity in the transferring process and the corner of the sliding frame c2 rubs to influence the product quality is avoided. After the constant-pressure mechanism c5 clamps the sheet, the ejection cylinder c62 drives the ejection roller c61 to reset to the initial position. It should be understood that the control system controls the action duration of the jacking driving mechanism, and the control system can be implemented by setting the existing control program.

In practical application, the plate positioning module b is provided with a position sensing assembly b9, when the position sensing assembly b9 senses a predetermined position, on one hand, the position sensing assembly b9 feeds back a signal to the control system, and the control system controls the plate positioning module b to start adjusting the transverse position of the plate; on the other hand, the situation that the plate d is about to be transited from the plate positioning module b to the plate transferring module c is explained, so that at the same time, the control system controls the action of the jacking driving mechanism, the jacking driving mechanism drives the material ejecting roller c61 to continuously perform reciprocating actions of ascending and descending within a set time, when the front end part of the plate d passes through the material ejecting roller c61, the front end of the plate d firstly abuts against the cambered surface of the material ejecting roller c61, the plate d continues to advance under the action of pushing force, and under the guiding action of the cambered surface of the material ejecting roller c61 and the action of elastic deformation of the front end of the plate d, the plate d is gradually unfolded and flattened above the material ejecting roller c61 from a downward bending state; in addition, under the action of continuous up-and-down reciprocating movement of the jacking roller c61, the front edge of the plate d swings up and down along with the jacking roller c61, and generally, after the plate is jacked up by the jacking roller c61, the plate d directly slides onto the top surface of the material supporting arm c4, so that the problem of shell clamping cannot occur; even if the front edge of the sheet metal is temporarily clamped at the rear end of the material supporting arm c4 and cannot continue to advance, the jacking roller c61 can quickly jack the sheet metal d upwards, so that the front edge of the sheet metal d smoothly goes over the top surface of the material supporting arm c4 and is pressed on the material supporting arm c4, and the problem of shell clamping is solved.

Specifically, the plate positioning module b comprises a fixed frame b1 arranged on the frame a, a plurality of material supporting rollers b2 arranged on the fixed frame b1 in a crossing manner, a positioning flange component b3 arranged on the fixed frame b1, a material pulling mechanism b4 for pulling the plate d to the positioning flange component b3, and a material pushing mechanism b5 for pushing the plate d to the positioning flange component b 3.

And when the single edge searching and positioning process is finished, the control system waits for the next edge searching signal to trigger, and after the single edge searching and positioning process is finished, the plate passes through for a long time without the condition of the edge searching signal or the midway edge searching caused by the disordered triggering.
