Description

Technical Field

[0001] The present invention relates to the technical field of steel sheet processing and transportation devices, and in particular to a feeding device for steel sheet processing and a use method thereof. Background Art

[0002] Steel sheets are made of stainless steel materials through heat treatment and fine grinding. They have the characteristics of high precision, strong tensile strength, good finish, toughness, and are not easy to break. They are mainly used in: electronic instruments, mold manufacturing, precision machinery, hardware parts, mechanical parts, stamping parts, small hardware manufacturing, etc. In the production process of steel sheets, it is necessary to go through cutting, grinding, hot pressing and other processes. In order to ensure that the process can proceed smoothly, feeding equipment is usually set up to transport the steel sheets.

[0003] In the related art, a Chinese patent with the announcement number CN215557199U discloses an automatic sequential feeding device for steel sheets, and the key points of its technical solution are: comprising a machine tool, a loading module installed at the bottom of the machine tool for loading, a clamping module installed on the upper side of the machine tool for clamping steel sheets, and a conveying module arranged on the right side of the clamping module for conveying steel sheets. The feeding device can realize sequential transportation of steel sheets through the setting of the loading module, so that the steel sheets are transported at a certain distance, and there is no need to manually place the steel sheets at a specific position for conveying. The steel sheets can be clamped by the clamping module, which cooperates with the loading module to clamp the steel sheets in sequence, and then convey the steel sheets through the conveying module, and steel sheet processing equipment can be installed on its outer side.

[0004] However, although the above patent solves the problem of automatic feeding during steel sheet processing, the following problems will still be encountered in actual application:

[0005] Before the gripper module grips the steel sheet, it needs to go through the conveyor module to load the steel sheet, but the steel sheet is directly placed on the top of the conveyor module. The position of the steel sheet is not restricted during the conveying process, that is, if the position of the steel sheet is offset and the position is not corrected before being gripped, the gripper module will not be able to grip it, which will affect the subsequent processing of the steel sheet.

[0006] In view of this, we propose a feeding device for steel sheet processing and a method of using the same to improve the deficiencies in the prior art. Summary of the invention

[0007] The object of the present invention is to provide a feeding device for steel sheet processing and a method of using the same, so as to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above-mentioned object, one of the objects of the present invention is to provide a feeding device for steel sheet processing, comprising a base, a feeding mechanism is provided at the top center of the base, a pair of first enclosures and a pair of second enclosures are respectively provided on both sides of the feeding mechanism at the top of the base, the first enclosures are located above the second enclosures, a plurality of pairs of correction mechanisms are provided on the tops of the two first enclosures, a transfer mechanism is provided on the tops of the two second enclosures, a clamping mechanism is provided on the tops of the two transfer mechanisms, and the spacing between each pair of the correction mechanisms is different;

[0009] The feeding mechanism is used to feed the steel sheet to be processed, the correcting mechanism is used to correct the steel sheet with position deviation, the transfer mechanism is used to change the relative position of the clamping mechanism and the feeding mechanism, and the clamping mechanism is used to clamp the steel sheet located below itself;

[0010] When the feeding method of the steel sheet is determined, the clamping mechanism is located on one side of a pair of correction mechanisms with the smallest spacing, so as to improve the positioning effect of the steel sheet between the multiple pairs of correction mechanisms;

[0011] When the feeding method of the steel sheet is uncertain, the clamping mechanism is located on one side of a pair of correction mechanisms with the largest spacing to prevent the steel sheet from getting stuck at the correction mechanisms, and the correction mechanisms with gradually increasing spacing can improve compatibility with the steel sheet size.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In the feeding equipment for processing steel sheets, the feeding mechanism is used to feed the steel sheets to be processed, the correction mechanism is used to correct the steel sheets with position deviation, the transfer mechanism is used to change the relative position of the clamping mechanism and the feeding mechanism, and the clamping mechanism is used to clamp the steel sheets located below itself.

[0014] 2. In the feeding equipment for processing steel sheets, when the feeding method of the steel sheets is determined, the clamping mechanism is located on one side of a pair of correction mechanisms with the smallest spacing, so as to improve the positioning effect of the steel sheets between multiple pairs of correction mechanisms; when the feeding method of the steel sheets is uncertain, the clamping mechanism is located on one side of a pair of correction mechanisms with the largest spacing, so as to prevent the steel sheets from getting stuck at the correction mechanisms, and the correction mechanisms with gradually increasing spacing can improve the compatibility with the steel sheet sizes.

[0015] On the basis of the above technical solution, the present invention can also make the following improvements:

[0016] As a further improvement of the present technical solution, the feeding mechanism includes a pair of conveying rollers arranged at intervals, the outer periphery of the two conveying rollers is wrapped with a conveyor belt, the wrapping angle between the two conveying rollers and the conveyor belt is between 120°-240°, and the conveying rollers are driven by a servo motor.

[0017] As a further improvement of the technical solution, the correction mechanism includes an extension frame fixedly connected to the top of the first enclosure, and the extension frame is provided with a correction wheel on a side close to the center of the conveyor belt.

[0018] As a further improvement of the technical solution, the correction wheel is rotatably connected to the extension frame.

[0019] As a further improvement of the technical solution, the spacing between each pair of the correction wheels changes gradually.

[0020] The beneficial effects of adopting the above-mentioned improvement scheme are that, first, when the steel sheet becomes skewed while being transported on the conveyor belt, its edge will contact the correction wheel. The correction wheel can rotate, and the pressure from the edge of the steel sheet will cause the correction to rotate. Since the position of the correction wheel 320 is fixed on both sides of the conveyor belt, it will produce a reaction force on the steel sheet. Secondly, when multiple correction wheels are used to correct the position of the steel sheet, the effect of guiding the position correction of the steel sheet can be produced by adjusting the rotation speed of the correction wheel. If the rotation speed of the correction wheel on one side is slightly faster than that of the other side, a speed difference will be generated when the edge of the steel sheet contacts the correction wheels on both sides. Moreover, the correction wheel and the conveyor belt form a structure similar to a "track", which limits the boundary range of the steel sheet. During normal transportation, a certain gap is maintained between the edge of the steel sheet and the correction wheel. The size of this gap is designed according to the size of the steel sheet and the transportation requirements.

[0021] As a further improvement of the present technical solution, the transfer mechanism includes a guide rail fixedly connected to the top of the second enclosure, a transfer seat is provided on the top of the guide rail, and the transfer seat is slidably connected to the guide rail.

[0022] As a further improvement of the technical solution, a plurality of pulleys are rotatably connected inside the transfer seat, each of the pulleys is rotatably connected to the outer wall of the guide rail, and the pulleys are driven by a servo motor.

[0023] The beneficial effect of adopting the above-mentioned improved scheme is that when the position of the clamping arm needs to be transferred, the servo motor driving the pulley is started, and the servo motor drives the pulley coaxially connected to its output shaft to rotate. Under the action of the friction force between the pulley and the guide rail, the two transfer seats synchronously drive the clamping mechanism to move on the top of the guide rail.

[0024] As a further improvement of the technical solution, the clamping mechanism at least includes a gantry fixedly connected to the tops of the two guide rails, a mounting seat is provided on one side of the gantry, and a pair of clamping arms is provided on the side of the mounting seat away from the gantry.

[0025] As a further improvement of the technical solution, the clamping mechanism further includes a hydraulic rod, a fixed portion of the hydraulic rod is fixedly connected to the gantry, and a movable portion of the hydraulic rod is fixedly connected to the mounting seat.

[0026] The beneficial effect of adopting the above-mentioned improvement scheme is that after the conveyor belt transports the steel sheet to be processed to the bottom of the clamping arm, the hydraulic rod drives the mounting seat to move downward, and the pair of clamping arms clamps the steel sheet on the top of the conveyor belt to the subsequent processing equipment.

[0027] The second object of the present invention is to provide a method for feeding equipment for steel sheet processing, comprising the following steps:

[0028] S1. Place the steel sheet to be processed on the top end of the feeding mechanism, and then start the feeding mechanism to feed the steel sheet;

[0029] S2. During the process of the feeding mechanism conveying the steel sheet, if the position of the steel sheet is offset, the correction mechanism corrects the position of the steel sheet;

[0030] S3, after the steel sheet is transferred to the bottom of the clamping mechanism, the clamping mechanism clamps the steel sheet to the subsequent processing equipment;

[0031] S4. When the feeding method of the steel sheet is determined, the clamping mechanism is located on one side of a pair of correction mechanisms with the smallest spacing, so as to improve the positioning effect of the steel sheet between multiple pairs of correction mechanisms;

[0032] S5. When the feeding method of the steel sheet is uncertain, the clamping mechanism is located on one side of a pair of correction mechanisms with the largest spacing to prevent the steel sheet from getting stuck at the correction mechanism, and the correction mechanism with gradually increasing spacing can improve the compatibility with the steel sheet size.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0053] Embodiment 1: In order to solve the problem of position deviation during the steel sheet feeding process mentioned in the above background technology, correction devices (i.e., correction mechanisms 300 hereinafter) are provided on both sides of the conveying device (i.e., the feeding mechanism 200 to be described hereinafter).

[0054] See also Figure 1-Figure 3 As shown, the purpose of this embodiment is to provide a feeding device for steel sheet processing, including a base 100, a feeding mechanism 200 is provided at the top center of the base 100, a pair of first enclosures 110 and a pair of second enclosures 120 are respectively provided on both sides of the feeding mechanism 200 at the top of the base 100, the first enclosure 110 is located above the second enclosure 120, a plurality of pairs of correction mechanisms 300 are provided on the tops of the two first enclosures 110, a transfer mechanism 400 is provided on the tops of the two second enclosures 120, a clamping mechanism 500 is provided on the tops of the two transfer mechanisms 400, and the spacing between each pair of correction mechanisms 300 is different;

[0055] The feeding mechanism 200 is used to feed the steel sheet to be processed, the correcting mechanism 300 is used to correct the steel sheet with position deviation, the transfer mechanism 400 is used to change the relative position of the clamping mechanism 500 and the feeding mechanism 200, and the clamping mechanism 500 is used to clamp the steel sheet located below itself;

[0056] When the feeding method of the steel sheet is determined, the clamping mechanism 500 is located on one side of a pair of correction mechanisms 300 with the smallest spacing, so as to improve the positioning effect of the steel sheet between the multiple pairs of correction mechanisms 300;

[0057] When the feeding method of the steel sheet is uncertain, the clamping mechanism 500 is located on one side of a pair of correction mechanisms 300 with the largest spacing to prevent the steel sheet from getting stuck at the correction mechanism 300, and the correction mechanism 300 with gradually increasing spacing can improve the compatibility with the steel sheet size.

[0058] Working principle:

[0059] First, the steel sheet to be processed is placed on the top end of the feeding mechanism 200, and then the feeding mechanism 200 is started to feed the steel sheet;

[0060] During the process of the feeding mechanism 200 conveying the steel sheet, if the position of the steel sheet is offset, the correction mechanism 300 corrects the position of the steel sheet; after the steel sheet is conveyed to the bottom of the clamping mechanism 500, the clamping mechanism 500 clamps the steel sheet to the subsequent processing equipment;

[0061] When the feeding method of the steel sheet is determined, the clamping mechanism 500 is located on one side of a pair of correction mechanisms 300 with the smallest spacing, so as to improve the positioning effect of the steel sheet between multiple pairs of correction mechanisms 300; when the feeding method of the steel sheet is uncertain, the clamping mechanism 500 is located on one side of a pair of correction mechanisms 300 with the largest spacing, so as to prevent the steel sheet from getting stuck at the correction mechanism 300, and the correction mechanisms 300 with gradually increasing spacing can improve the compatibility with the steel sheet size.

[0062] like Figure 4 As shown, the feeding mechanism 200 includes a pair of conveying rollers 210 arranged at intervals, and the outer periphery of the two conveying rollers 210 is wrapped with a conveyor belt 220. The wrapping angle between the two conveying rollers 210 and the conveyor belt 220 is between 120° and 240°. The conveying rollers 210 are driven by a servo motor.

[0063] That is to say, after the steel sheet to be processed is placed on the top of the conveyor belt 220, the power of the servo motor driving the conveyor roller 210 is turned on, the servo motor drives the conveyor roller 210 to rotate, and the conveyor roller 210 drives the conveyor belt 220 to rotate. Under the action of the friction force of the conveyor belt 220 on the steel sheet, the steel sheet is driven to move toward the clamping mechanism 500.

[0064] Since the steel sheet is directly placed on the top of the conveyor belt 220, the position of the steel sheet is not restricted during the conveying process, that is, if the position of the steel sheet is offset and the position is not corrected before being clamped, the clamping mechanism 500 will not be able to clamp it, which will affect the subsequent processing of the steel sheet.

[0065] exist Figure 5 In the figure, the correction mechanism 300 includes an extension frame 310 fixedly connected to the top of the first enclosure 110, and the extension frame 310 is provided with a correction wheel 320 on one side close to the center of the conveyor belt 220.

[0066] The improvement lies in that the correction wheel 320 is rotatably connected to the extension frame 310 .

[0067] Furthermore, the distance between each pair of correction wheels 320 changes gradually.

[0068] The working principle of the correction wheels 320 arranged on both sides of the conveyor belt 220 to correct the position of the skewed steel sheet is as follows:

[0069] (1) Contact guiding principle: When the steel sheet is skewed while being transported on the conveyor belt 220, its edge will contact the correction wheel 320. The correction wheel 320 is rotatable, and the pressure from the edge of the steel sheet will cause the correction wheel 320 to rotate. Since the correction wheel 320 is fixed on both sides of the conveyor belt 220, it will generate a reaction force on the steel sheet.

[0070] For example, if the steel sheet tilts to the right and contacts the right correction wheel 320, the correction wheel 320 will rotate to the left under the push of the steel sheet, and at the same time give the steel sheet a leftward reaction force. This reaction force will cause the front end (forward direction) of the steel sheet to produce a leftward displacement component, and under the continuous forward conveyance of the conveyor belt 220, the steel sheet will gradually move to the left, thereby correcting its position and returning it to the correct conveying route.

[0071] (2) Speed ​​difference guiding principle: When multiple correction wheels 320 are used to correct the position of the steel sheet, the effect of guiding the position correction of the steel sheet can be achieved by adjusting the rotation speed of the correction wheel 320. If the rotation speed of the correction wheel 320 on one side is slightly faster than that of the other side, a speed difference will be generated when the edge of the steel sheet contacts the correction wheels 320 on both sides.

[0072] For example, when the steel sheet is tilted to the left, the rotation speed of the right correction wheel 320 is increased so that the right edge of the steel sheet moves faster than the left edge. Under the effect of this speed difference, the steel sheet will generate a rightward correction force, causing the steel sheet to gradually move to the right and return to the correct position. This principle is similar to the situation when a car turns due to the speed difference between the inner and outer wheels.

[0073] (3) Limiting Boundary Principle: The correction wheel 320 and the conveyor belt 220 form a "track"-like structure that limits the boundary range of the steel sheet. During normal transportation, a certain gap is maintained between the edge of the steel sheet and the correction wheel 320. The size of this gap is designed according to the size of the steel sheet and the transportation requirements.

[0074] When the steel sheet is skewed, the part beyond the normal position will enter the restricted area. For example, if the steel sheet is skewed to the left, the left part will enter the range restricted by the correction wheel 320, and the correction wheel 320 will prevent the steel sheet from further deviating to the left. As the conveyor belt 220 continues to transport, the steel sheet can only move along the boundary range specified by the correction wheel 320 under the restriction of the correction wheel 320, so as to restore to the correct position, ensuring that the steel sheet is transported at the center position of the conveyor belt 220 or the preset correct position, so that the subsequent clamping mechanism 500 can accurately clamp it.

[0075] It should be noted that in different scenarios, the feeding method for steel sheets is different. The spacing of the correction wheel 320 is set to change gradually. When the steel sheet is skewed on the conveyor belt 220, as it moves along the gradually changing correction wheel 320 channel, it will gradually return to the correct position under the constraint of the correction wheel 320, just like being guided into a specific track, which effectively improves the accuracy of the steel sheet conveying position. The gradually changing spacing can adapt to steel sheets of different widths. For wider or narrower steel sheets, appropriate guidance can be obtained at different positions of the channel, so that the equipment can handle steel sheets of various specifications, enhancing the versatility of the equipment. Compared with the correction wheel 320 with a fixed spacing, the gradually changing spacing allows the steel sheet to have a transition adjustment process. If it is a correction wheel 320 with a small fixed spacing, the steel sheet may be stuck or damaged due to a sudden collision when it is skewed. The gradual spacing can make the steel sheet transition to the correct position more smoothly, reduce the collision force between the steel sheet and the correction wheel 320, and protect the integrity of the steel sheet.

[0076] Suitable for the scenario where the distance between the correction wheels 320 is gradually increased (the clamping mechanism 500 is transferred to the side of the pair of correction wheels 320 with the largest distance through the transfer mechanism 400): When the initial position of the steel sheet entering the conveyor belt 220 is relatively uncertain, such as manual loading or unloading from the storage device in a more random manner, the gradually increasing distance between the correction wheels 320 can provide a larger error tolerance. This ensures that the steel sheet can more easily enter the channel between the correction wheels 320 and avoid being stuck at the entrance due to inaccurate initial position.

[0077] For example, in some small workshop-style steel sheet processing scenarios, workers manually place steel sheets on the conveyor belt 220. Due to the inaccuracy of manual operation, the steel sheets may enter at various positions and angles. In this case, the correction wheels 320 with gradually increasing spacing from the exit end to the entrance end, such as a larger spacing at the entrance (e.g., 60-80 cm), can allow the steel sheets to enter the correction area more smoothly.

[0078] Suitable for the scenario where the spacing between the correction wheels 320 is gradually reduced (the clamping mechanism 500 is transferred to the side of the pair of correction wheels 320 with the smallest spacing through the transfer mechanism 400): When the subsequent processing technology (such as precision stamping, laser cutting, etc.) requires extremely high position accuracy of the steel sheet, the correction wheels 320 with gradually reduced spacing can accurately position the steel sheet to the required position. The gradual reduction of the spacing between the correction wheels 320 is like a closed funnel, which can make the steel sheet gradually move closer to the center position, ensuring the accuracy of the final position.

[0079] For example, in the high-precision stamping process of automobile parts, the steel sheet needs to be accurately positioned directly above the stamping die. Setting the spacing of the correction wheels 320 from a larger size at the entrance (such as 80 cm) to a suitable size at the exit (such as 40 cm) can ensure that the steel sheet reaches a very high position accuracy before being transported to the stamping equipment.

[0080] like Figure 6 As shown, the specific structure of the transfer mechanism 400 is disclosed below. The transfer mechanism 400 includes a guide rail 410 fixedly connected to the top of the second enclosure 120. A transfer seat 420 is provided on the top of the guide rail 410. The transfer seat 420 is slidably connected to the guide rail 410.

[0081] Furthermore, a plurality of pulleys 430 are rotatably connected inside the transfer seat 420 , and each pulley 430 is rotatably connected to the outer wall of the guide rail 410 , and the pulley 430 is driven by a servo motor.

[0082] It should be noted that when the position of the clamping mechanism 500 needs to be transferred, the servo motor driving the pulley 430 is started, and the servo motor drives the pulley 430 coaxially connected to its output shaft to rotate. Under the action of the friction force between the pulley 430 and the guide rail 410, the two transfer seats 420 synchronously drive the clamping mechanism 500 to move on the top of the guide rail 410.

[0083] Based on the above working process of the correction wheel 320, combined with Figure 7-Figure 11 The coordination process between the correction wheel 320 and the clamping mechanism 500 is explained. The clamping mechanism 500 at least includes a gantry 130 fixedly connected to the top of the two guide rails 410. A mounting seat 510 is provided on one side of the gantry 130. The mounting seat 510 is provided with a pair of clamping arms 520 on the side away from the gantry 130.

[0084] It should be noted that the clamping mechanism 500 further includes a hydraulic rod 530 , a fixed portion of the hydraulic rod 530 is fixedly connected to the gantry 130 , and a movable portion of the hydraulic rod 530 is fixedly connected to the mounting seat 510 .

[0085] That is to say, after the conveyor belt 220 transports the steel sheet to be processed to the bottom of the clamping arm 520, the hydraulic rod 530 drives the mounting seat 510 to move downward, and the pair of clamping arms 520 clamp the steel sheet on the top of the conveyor belt 220 to the subsequent processing equipment.

[0086] Embodiment 2: This embodiment is based on the content provided in Embodiment 1, and aims to provide a method for a feeding device for steel sheet processing, and the specific steps are as follows:

[0087] S1. After placing the steel sheet to be processed on the top of the conveyor belt 220, turn on the power of the servo motor driving the conveyor roller 210. The servo motor drives the conveyor roller 210 to rotate, and the conveyor roller 210 drives the conveyor belt 220 to rotate. Under the action of the friction force of the conveyor belt 220 on the steel sheet, the steel sheet is driven to move below the clamping arm 520.

[0088] S2. When the steel sheet is skewed while being transported on the conveyor belt 220, its edge will contact the correction wheel 320. The correction wheel 320 can rotate, and the pressure from the edge of the steel sheet will cause the correction wheel 320 to rotate. Since the position of the correction wheel 320 is fixed on both sides of the conveyor belt 220, it will produce a reaction force on the steel sheet; when multiple correction wheels 320 are used to correct the position of the steel sheet, the rotation speed of the correction wheel 320 can be adjusted to produce the effect of guiding the position correction of the steel sheet. If the rotation speed of the correction wheel 320 on one side is slightly faster than that of the other side, a speed difference will be generated when the edge of the steel sheet contacts the correction wheels 320 on both sides. Ensure that the steel sheet is transported at the center position of the conveyor belt 220 or the preset correct position so that the subsequent clamping mechanism 500 can accurately clamp it.

[0089] S3. When the position of the clamping arm 520 needs to be transferred, the servo motor driving the pulley 430 is started, and the servo motor drives the pulley 430 coaxially connected to its output shaft to rotate. Under the action of the friction force between the pulley 430 and the guide rail 410, the two transfer seats 420 synchronously drive the clamping mechanism 500 to move on the top of the guide rail 410.

[0090] S4. When the feeding method of the steel sheet is determined, that is, when the subsequent processing technology (such as precision stamping, laser cutting, etc.) requires extremely high position accuracy of the steel sheet, the correction wheel 320 with gradually decreasing spacing can accurately position the steel sheet to the required position. By gradually reducing the spacing of the correction wheel 320, like a closed funnel, the steel sheet can gradually move closer to the center position to ensure the accuracy of the final position.

[0091] S5. When the feeding method of the steel sheet is uncertain, such as manual feeding or unloading from the storage device in a more random manner, the gradually increasing spacing between the correction wheels 320 can provide a larger margin for error. This ensures that the steel sheet can more easily enter the channel between the correction wheels 320 and avoid being stuck at the entrance due to inaccurate initial position.

[0092] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
