Embodiments

[0028] As Figures 1-6 shown, the utility model provides a kind of metal substrate input device, including the input mechanism 1 of feeding substrate stack 4, the sorting mechanism 2 of sorting single substrate and the output mechanism 3 of confirming and feeding substrate, sorting mechanism 2 includes frame body 5, substrate moving module 22 and substrate grabbing module 23;

[0029] Substrate moving module 22 is provided with the rolling module 221 of substrate stack 4 x-axis direction movement, the conveying module 222 of parallel arrangement and the lifting module 223 of substrate stack 4 switching track, conveying module 222 is set in the upper of rolling module 221 by rolling module 221, lifting module 223 is set in the bottom of rolling module 221 and is fixedly connected with frame body 5, substrate stack 4 into sorting mechanism 2 is moved to target position by rolling module 221 in x-axis direction, then lifting module 223 controls the height of rolling module 221 to drop so that substrate stack 4 falls into conveying module 222, and is driven by conveying module 222 to move in circumferential direction to reach the lower of substrate grabbing module 23;

[0030] Substrate grabbing module 23 is provided with movable frame 231, three-axis track 232 of supporting movable frame 231 movement and electric cylinder 233 matched with three-axis track 232, three-axis track 232 is fixed in frame body 5, electric cylinder 233 is fixed on one side of three-axis track 232, movable frame 231 is slidably connected with three-axis track 232, movable frame 231 is provided with two rows of several vacuum suction heads 234, movable frame 231 is positioned on three-axis track 232 under the drive of electric cylinder 233, and vacuum suction head 234 is lowered to the edge of substrate and is lifted to target position after being sucked, and then is lowered.

[0031] Rolling module 221, the substrate stack 4 moves along the x-axis direction on the rolling module 221, and is adjusted according to the target position preset or detected by the sensor.

[0032] Lifting module 223, when the substrate stack 4 moves to the target position, the lifting module 223 starts to work, reduces the height of the rolling module 221, so that the substrate stack 4 is separated from the rolling module 221, and falls into the conveying module 222 below.

[0033] Conveying module 222, the substrate stack 4 is driven on the conveying module 222 and moves along the circumferential direction. This allows the substrate stack 4 to realize multi-dimensional movement in a limited physical space, facilitating subsequent sorting and grabbing operations.

[0034] Positioning of movable frame 231, electric cylinder 233 drives movable frame 231 to slide on three-axis track 232, and positions movable frame 231 to the target position above substrate stack 4 according to the preset or sensor detected position information.

[0035] Vacuum suction head 234 action, movable frame 231 moves down, vacuum suction head 234 contacts the edge of the substrate and starts vacuum suction to suck up the substrate.

[0036] Substrate conveying and putting down, after sucking up the substrate, movable frame 231 slides on three-axis track 232 to convey the substrate to the target position (such as output mechanism 3 or the next processing link), and then releases the vacuum suction to put down the substrate.

[0037] Through the input mechanism 1, the stacked metal substrates can be automatically fed into the sorting mechanism 2, reducing the trouble of manual handling and improving the work efficiency.

[0038] The sorting mechanism 2 can accurately sort single metal substrates from the substrate stack 4 through the cooperation of the substrate moving module 22 and the substrate grabbing module 23. The substrate moving module 22 is responsible for moving the substrate stack 4 in the x-axis and y-axis directions, and switching the track through the lifting module 223, so that the substrate stack 4 can be accurately moved to the position below the substrate grabbing module 23.

[0039] The substrate grabbing module 23 is driven by the cooperation of the movable frame 231 and the three-axis track 232 fixed in the frame body 5, and the electric cylinder 233. The three-axis track 232 provides the movable frame 231 with a moving path in three directions (usually X-axis, Y-axis and Z-axis). The movable frame 231 is in sliding connection with the three-axis track 232 and can move freely on the three-axis track 232. The movement of the movable frame 231 on the three-axis track 232 is driven by the electric cylinder 233. The movable frame 231 slides on the three-axis track 232 through the extension and retraction movement of the electric cylinder 233. The design of the three-axis track 232 enables the movable frame 231 to achieve accurate positioning and movement in the X-axis, Y-axis and Z-axis directions. Through the accurate control of the electric cylinder 233, the movable frame 231 can be accurately moved above the substrate and realize the downward movement and lifting operation of the vacuum suction head 234, so as to be flexibly moved and positioned above the substrate. Then, the edge of the substrate is sucked up by the vacuum suction head 234 and is transported to the target position and then is lowered. The movable frame 231 is provided with two rows of vacuum suction heads 234 for sucking the substrate. When the movable frame 231 is positioned above the substrate, the vacuum suction head 234 starts to work and generates negative pressure to suck up the substrate. This grabbing method is not only accurate and efficient, but also can reduce damage due to the soft suction head.

[0040] After sorting and grabbing, the metal substrate is sent to the output mechanism 3 for confirmation and output. In this way, the entire process is automated, greatly improving production efficiency and accuracy.

[0041] Since the device realizes automatic sorting and conveying, the manual operation link is reduced, so as to reduce errors and damage caused by human factors, thereby improving production quality.

[0042] The automatic sorting and grabbing mechanism reduces the demand for manpower and reduces production costs.

[0043] Automatic processing reduces human errors and improves the accuracy of substrate sorting and grabbing.

[0044] By adjusting the configuration of the sorting mechanism 2 and the grabbing module, the production needs of different products can be met, and the flexibility and scalability of the production line are improved.

[0045] Automatic processing reduces manual operation, reduces the labor intensity of workers, and reduces potential safety hazards caused by improper manual operation.

[0046] Referring to Figures 2 to 6, the rolling module 221 is provided with a base 301, a first motor 302 and a plurality of first rotating shafts 303 are installed below the base 301, one end of the first rotating shaft 303 is connected with a first toothed disc 304 of a movable end of the first motor 302, the first toothed discs 304 are meshed and connected with a chain 305, the first motor 302 drives the chain 305 to roll in the same direction, so that the substrate stack 4 placed thereon is translated;

[0047] The conveying module 222 is provided with two or more rows of support parts 401 parallel to the first rotating shaft 303, the support parts 401 are movably connected with a belt 402, the middle end of the support part 401 is provided with a second motor 403 and a second rotating shaft 404, the second rotating shaft 404 is fixedly connected with a movable end of the second motor 403, the second motor 403 drives the rotating shaft to rotate to drive the belt 402 to move in the same direction, so that the substrate stack 4 placed thereon is translated;

[0048] The lifting module 223 is provided with a support plate 501, the support plate 501 is provided with a first air cylinder 502 and a plurality of column bodies 503, the column bodies 503 are vertically placed to form a support surface, the column bodies 503 penetrate the base 301 of the rolling module 221, the first air cylinder 502 is connected with the support plate 501 and the base 301 of the rolling module 221 respectively, the first air cylinder 502 pushes up the rolling module 221 to separate the substrate stack 4 placed thereon from the conveying module 222.

[0049] The substrate stack 4 is translated in the y-axis direction, the rolling module 221 drives the first rotating shaft 303 to rotate through the first motor 302, and then drives all the first rotating shafts 303 to roll in the same direction through the chain 305, so that the substrate stack 4 placed on the rolling module 221 can move stably in the y-axis direction, facilitating the conveying of the substrate stack 4 to the designated sorting position.

[0050] The base 301 of the rolling module 221 and the first rotating shaft 303 jointly constitute a platform for supporting the substrate stack 4, ensuring that the substrate stack 4 remains stable during movement.

[0051] The substrate stack 4 is translated in the x-axis direction, the conveying module 222 drives the second rotating shaft 404 to rotate through the second motor 403, and then drives the belt 402 to move in the same direction, so that the substrate stack 4 placed on the conveying module 222 can move in the x-axis direction, facilitating the conveying of the substrate stack 4 to the lower side of the substrate grabbing module 23.

[0052] The lifting module 223 drives the support plate 501 to rise or fall through the first air cylinder 502, and then drives the base 301 of the rolling module 221 and the substrate stack 4 to rise or fall together. When the substrate stack 4 needs to be switched to the conveying module 222, the lifting module 223 lifts the rolling module 221, so that the substrate stack 4 contacts the belt 402 of the conveying module 222 and smoothly transitions to the conveying module 222.

[0053] After the substrate stack 4 is transported to the transport module 222, the lifting module 223 separates the rolling module 221 from the transport module 222 by lowering the support plate 501, preparing for the next round of substrate stack 4 input and sorting.

[0054] The coordinated work of the rolling module 221, the transport module 222 and the lifting module 223 realizes the full automation process of the substrate stack 4 from input to sorting to output, greatly improves the production efficiency and reduces the manual intervention. Through the precise control of the motor and the cylinder, the precise control of the moving speed and position of the substrate stack 4 can be realized, which helps to ensure the stability and accuracy of the substrate stack 4 in the sorting process.

[0055] Referring to Figure 4 , the first rotating shaft 303 of the rolling module 221 is provided with a friction wheel 306, and the friction wheel 306 is fixed to the first rotating shaft 303 to increase the friction to prevent slipping.

[0056] The friction wheel 306 increases the friction force between the substrate stack 4. When the substrate stack 4 is placed on the rolling module 221, the contact surface between the friction wheel 306 and the substrate stack 4 will generate enough normal force, so as to generate enough friction force between the contact surfaces. This helps to maintain the stability of the substrate stack 4 on the rolling module 221, preventing it from slipping or deviating due to external force during movement.

[0057] Referring to Figure 4 , the transport module 222 is provided with a fixed wheel 405 and a movable wheel 406. The fixed wheel 405 is arranged at the contact position of the second rotating shaft 404 and the belt 402 to increase the contact area, and the movable wheel 406 is fixed above both sides of the fixed wheel 405 to change the position of the belt 402.

[0058] The fixed wheel 405 is arranged at the contact position of the second rotating shaft 404 and the belt 402, which increases the contact area between the rotating shaft and the belt 402, and further increases the friction between the rotating shaft and the belt 402, preventing the rotating shaft and the belt 402 from slipping.

[0059] The fixed wheel 405 provides stable support for the belt 402, which helps to maintain the tension and stability of the belt 402. This ensures that the belt 402 will not be loose or jump during operation, thereby improving the accuracy and efficiency of the transport.

[0060] The movable wheels 406 are fixed above the two sides of the fixed wheels 405, and their main function is to change the position of the belt 402. By adjusting the height and angle of the movable wheels 406, the tension of the belt 402 can be adjusted, so as to ensure that the belt 402 always maintains appropriate tension during operation. In addition, the movable wheels 406 can also help the belt 402 to transition more smoothly when turning or changing direction, reducing friction and wear between the belt 402 and the support part 401.

[0061] By adjusting the height, angle and position of the movable wheels 406, the conveying module 222 can adapt to different sizes and shapes of the substrate stack 4, thereby meeting more diversified sorting needs.

[0062] The arrangement of the fixed wheels 405 and the movable wheels 406 helps to disperse the pressure generated by the belt 402 during operation, reducing friction and wear, thereby prolonging the service life of the belt 402 and the entire conveying module 222.

[0063] Referring to Figure 4 , the base 301 of the rolling module 221 is provided with a rotary clamping cylinder 307, and a limiting piece 309 is arranged on the opposite side of the rotary clamping cylinder 307. The movable end of the rotary clamping cylinder 307 is connected with an "L"-shaped blocking piece 308, and the blocking piece 308 cooperates with the limiting piece 309 to clamp and stabilize the substrate stack 4.

[0064] When the substrate stack 4 is placed on the rolling module 221, the rotary clamping cylinder 307 drives the "L"-shaped blocking piece 308 to move towards the limiting piece 309, and the two cooperate to clamp the substrate stack 4. This clamping action can ensure that the substrate stack 4 does not slip or deviate during movement due to external forces, thereby maintaining its stability.

[0065] During sorting, if the substrate stack 4 is unstable, it may need to be adjusted frequently, which will waste a lot of time. By arranging the rotary clamping cylinder 307 and the blocking piece 308, the stability of the substrate stack 4 during movement can be ensured, thereby reducing the adjustment time and improving the sorting efficiency.

[0066] Referring to Figure 4 , the base 301 is a rectangular base 301, and the rotary clamping cylinder 307 is two groups of cylinders, which are arranged on the side surface and the adjacent side surface of the base 301, respectively, and the opposite sides are provided with limiting pieces 309.

[0067] Since the two groups of cylinders are arranged on the side surface and the adjacent side surface of the base 301, respectively, they can clamp the substrate stack 4 in both directions at the same time. This clamping method is more stable than one-way clamping, which can effectively prevent the substrate stack 4 from slipping or deviating during movement due to external forces.

[0068] The design of the rectangular base 301 itself has good stability, and the two-way clamping action of the two groups of air cylinders can further enhance the stability of the substrate stack 4 during movement.

[0069] The electric cylinder 233 is a ball screw electric cylinder 233.

[0070] The ball screw electric cylinder 233 realizes motion transmission through the rolling of balls between the screw shaft and the nut. This rolling motion mode has minimal friction resistance, smooth motion, and can realize high-precision linear motion. Under the cooperation of servo control, the ball screw electric cylinder 233 can achieve extremely high positioning accuracy, such as 0.01 mm or even higher, and is suitable for occasions with extremely high position accuracy requirements.

[0075] II. Substrate stack 4 enters the sorting mechanism 2

[0076] The rolling module 221 starts: the first motor 302 starts, drives the first rotating shaft 303 to roll in the same direction through the chain 305 transmission, and the friction wheel 306 increases the friction to prevent the substrate stack 4 from slipping during rolling.

[0077] The substrate stack 4 translates in the x-axis direction with the rolling of the first rotating shaft 303.

[0078] III. Substrate stack 4 positioning and switching track

[0079] The substrate stack 4 is positioned, and when the substrate stack 4 moves to the target position, the rotary clamping air cylinder 307 drives the "L" type blocking piece 308 to cooperate with the limiting piece 309 to clamp and stabilize the substrate stack 4, wherein the design of the rectangular base 301 and the two groups of air cylinders ensures the stability of the substrate stack 4 during positioning.

[0080] The first air cylinder 502 pushes up the support plate 501, so that the height of the base 301 of the rolling module 221 is lowered.

[0081] The substrate stack 4 falls onto the support part 401 of the conveying module 222.
