Description

Technical Field

[0001] The invention relates to the technical field of low-sugar biscuit detection, and in particular to a reversible low-sugar biscuit defect detection device. Background Art

[0002] Low-sugar biscuits are a specially designed health food. Their main feature is that they use ingredients with a low glycemic index to reduce the rapid impact on blood sugar. Compared with traditional biscuits, low-sugar biscuits are more suitable for diabetics, people who want to lose weight, and consumers who pay attention to blood sugar control. When producing low-sugar biscuits, machine vision optical inspection technology is needed to detect whether there are large pores and burnt defects on the surface of the biscuits.

This patent can quickly realize the quality inspection function of biscuits and automatically distinguish defective biscuits from qualified biscuits through the cooperation of the detection system with the drive motor, the turntable and the detection frame, greatly reducing the labor cost and improving the efficiency of biscuit quality inspection. However, in actual use, this type of detection device can usually only perform visual inspection on the top of the biscuit, and it is not convenient to detect the bottom of the biscuit, so that after a round of inspection, the bottom of the biscuit needs to be re-inspected to completely complete the biscuit sorting operation, resulting in the problem of low overall efficiency.

An electric push rod is arranged inside one end of the limit ring, and the end of the electric push rod is connected to the limit block.

[0016] The present invention provides a reversible low-sugar biscuit defect detection device, which has the following beneficial effects:

[0017] 1. According to the present invention, when the feeding tray moves the biscuit to the clamping assembly, the servo motor can control the reciprocating screw to rotate, so that the driving seat moves up along the light rod. At this time, the compression spring will press the lifting seat against the convex ring in the middle of the lifting frame, so that the clamping assembly can work normally. After clamping the biscuit, as the driving seat continues to move up, the lifting seat will squeeze the compression spring to shrink it, thereby driving the biscuit to move up one end distance to prevent obstruction during flipping. After that, the ratchet will contact the tooth plate. At this time, the pawl and the ratchet will slide, so as not to limit the rotation of the first damping shaft, and the biscuit can be automatically flipped while it rises. When the driving seat moves down, the inclined surface on the spring seat will contact the inclined surface on the tooth plate, so as to provide a certain horizontal component force to squeeze the spring seat. At the same time, the ratchet will resist the teeth of the ratchet to prevent the first damping shaft from rotating. Therefore, slippage will occur between the tooth plate and the ratchet, and no transmission will be performed. Therefore, after the biscuit is flipped, the biscuit remains stable and falls back onto the support plate, so that the next visual detector can perform visual defect detection on the other side of the biscuit.

[0018] 2. The inner curvature of the outer groove of the feed plate of the present invention matches the round biscuits produced, so when the feed plate rotates, the centrifugal force can be used to make the outer side of the biscuit fit with the arc of the groove, and the biscuit is automatically positioned. At the same time, the groove is large, which is convenient for taking and placing the biscuits. At the same time, the opening on the support plate is convenient for the clamping plate to pass through. Therefore, in the process of the driving seat moving up, the guide block can be pushed to move up along the guide rod, thereby driving the sliding column to move horizontally, so that the driving plate drives the sliding sleeve to move to one end of the first damping shaft, so that the connecting rod can push the clamping plate to clamp the biscuits, and the buffer pad can be used to avoid damaging the biscuits. , and when the splint is horizontal, the end of the first damping shaft will block the rotation of the splint, and the splint will not continue to rotate at this time, so as to avoid excessive force and damage to the biscuits. After clamping, the sliding sleeve cannot slide, so the first damping shaft can be driven to move upward to perform the flipping operation. In the flipping process, since the driving plate is rotatably connected to the sliding sleeve, no motion interference will occur. When the driving seat moves downward and separates from the guide block, the guide block is heavier and can pull the sliding column. Similarly, the splint can automatically release the biscuits, so that the biscuits can be flipped one by one during continuous production.

[0019] When the driving seat moves downward, the driving column will squeeze the driving column to move downward, so that the rack contacts the active gear, and the rotating seat can be driven to rotate through the second damping shaft, the driven gear and the gear ring to automatically feed the biscuits on the outer end of the feeding plate. After the feeding plate rotates one-sixth of a circle, the driving column will drive the rack to slide along the fixed rod under the guidance of the inclined surface of the lower part of the limiting plate, so that the rack is automatically separated from the active gear. At this time, under the damping action of the second damping shaft, the continuous rotation of the rotating seat can be limited to avoid excessive rotation due to inertia. When the driving seat moves upward, the magnet can absorb the iron driving column, thereby driving the rack, the fixed rod and the slider to move upward together, and when the driving seat moves to the inclined surface at the upper part of the limiting plate, it will slide along the fixed rod again and move to the top of the active gear. Therefore, in the process of reciprocating up and down movement, the feeding operation of the feeding plate can be automatically controlled without adding an additional power source.

[0020] 4. The present invention can utilize the limit ring to limit and block the end of the slide bar, so that the block supports the bottom of the support plate, so that the biscuits can be placed in the groove outside the feeding tray, and the grooves outside the feeding tray are respectively for loading, first detection, turning over, second detection, defective product rejection and unloading positions, and the concave portion of the limit ring corresponds to the unloading position. Therefore, when the feeding tray moves qualified products here, the return spring will push the slide bar under the limit of the fixed ear, so that the block slides, the support plate will rotate to an inclined state, and the biscuits will slide along the support plate to the conveyor belt below for automatic unloading. When a defective product is encountered, the electric push rod can be started by the controller to separate the limit block from the slide bar, and the defective product can slide to another conveyor belt below, so that the biscuits can be automatically sorted after detection, thereby improving the degree of automation of the equipment.

[0030] See also Figures 1 to 5 The driving assembly 6 includes a polished rod 601, a top plate 602 and a servo motor 603. The polished rod 601 is arranged at one end of the top of the base 4, and the top plate 602 is fixed on the top of the polished rod 601, and the servo motor 603 is arranged on the top of the top plate 602. The driving assembly 6 also includes a reciprocating screw 604, a driving seat 605 and a magnet 606. The bottom of the servo motor 603 is connected to the reciprocating screw 604, and the driving seat 605 is arranged on the outer side of the middle part of the reciprocating screw 604, and the magnet 606 is fixed inside the driving seat 605. A clamping assembly 7 is arranged on the upper end of one side of the driving seat 605. The clamping assembly 7 includes a guide block 701 and a guide rod 702. The guide block 701 is arranged on the top of one end of the driving seat 605, and the guide rod 702 is slidably connected inside one end of the guide block 701. , the middle part of the guide rod 702 is convex, and the guide rod 702 is fixedly connected to the base 4, the clamping assembly 7 also includes a slide column 703, a drive plate 704 and a sleeve 705, the guide block 701 is internally slidably connected with the slide column 703, and the end of the slide column 703 is fixed with the drive plate 704, and the drive plate 704 is internally rotatably connected with the slide sleeve 705, the clamping assembly 7 also includes a first damping shaft 706, a connecting rod 707, a clamping plate 708 and a buffer pad 709, the interior of the sleeve 705 is slidably connected with the first damping shaft 706, and the first damping shaft 706 is rotatably connected to the lifting seat 802, the upper and lower ends of the sleeve 705 are rotatably connected with the connecting rod 707, and the end of the connecting rod 707 is rotatably connected with the clamping plate 708, and a buffer pad 709 is provided on one side of the clamping plate 708;

[0031] The specific operation is as follows: the visual detector 5 will take a picture of the biscuit below for detection, and when the biscuit moves to the clamping assembly 7, the servo motor 603 can control the reciprocating screw 604 to rotate, so that the drive seat 605 moves up along the light rod 601. At this time, the compression spring 803 will press the lifting seat 802 against the convex ring in the middle of the lifting frame 801. Therefore, during the upward movement of the drive seat 605, the guide block 701 can be pushed to move up along the guide rod 702, thereby driving the sliding column 703 to move horizontally, so that the drive plate 704 drives the sliding sleeve When 705 moves to one end of the first damping shaft 706, the connecting rod 707 can push the clamping plate 708 to clamp the biscuit, and the buffer pad 709 can be used to avoid damaging the biscuit. When the clamping plate 708 is horizontal, the end of the first damping shaft 706 will block the rotation of the clamping plate 708, and the clamping plate 708 will not continue to rotate, avoiding excessive force from damaging the biscuit. After clamping, the sliding sleeve 705 cannot slide, so it can drive the first damping shaft 706 to move upward, and the lifting seat 802 will squeeze the compression spring. 803 is contracted, thereby driving the biscuit to move up a distance to prevent it from being blocked when turning over. Then the ratchet 805 contacts the tooth plate 808. At this time, the pawl 804 slides with the ratchet 805, thereby not restricting the rotation of the first damping shaft 706. The biscuit can be automatically turned over while it rises. In the process of turning over, since the driving plate 704 is rotatably connected with the sliding sleeve 705, no motion interference occurs. When the driving seat 605 moves downward, the inclined surface on the spring seat 807 contacts the inclined surface on the tooth plate 808. The inclined surface of the biscuit 605 contacts with the guide block 701, which can provide a certain horizontal component force to squeeze the spring seat 807. At the same time, the ratchet 805 will resist the teeth of the ratchet 805 to prevent the first damping shaft 706 from rotating. Therefore, the tooth plate 808 and the ratchet 805 will slip and no transmission will be performed. Therefore, after the biscuit is turned over, the biscuit can remain stable and fall back onto the support plate 2. When the drive seat 605 moves down and separates from the guide block 701, the guide block 701 is heavier and can pull the slide column 703. Similarly, the clamping plate 708 can automatically release the biscuit.

[0032] See also Figures 3 to 7, a material moving assembly 9 is connected to the outer side of the rotating seat 3, and the material moving assembly 9 includes a limit plate 901, a slider 902, a fixed rod 903, a rack 904 and a driving column 905.

The material moving assembly 9 also includes a second damping shaft 906, a driving gear 907, a driven gear 908 and a gear ring 909. The top of the base 4 is rotatably connected to the second damping shaft 906, and a driving gear 907 is fixed to one end of the second damping shaft 906, and a driven gear 908 is arranged on the other end of the second damping shaft 906, and the upper end of the driven gear 908 is meshed with the second damping shaft 906 , and the second damping shaft 906 is fixedly connected to the rotating seat 3, a discharge assembly 10 is arranged at the bottom of the feeding tray 1, and the discharge assembly 10 includes a fixed ear 1001, a slide bar 1002, a stopper 1003 and a return spring 1004, a fixed ear 1001 is fixed to the outer end of the bottom of the feeding tray 1, and the fixed ear 1001 is slidably connected to the inside of the fixed ear 1001, a stopper 1003 is arranged at one end of the slide bar 1002, and a return spring 1004 is sleeved at the other end of the slide bar 1002, the discharge assembly 10 also includes a limit ring 1005, an electric push rod 1006 and a limit block 1007, the other end of the fixed ear 1001 is slidably connected to the limit ring 1005, and the limit ring 1005 is fixedly connected to the base 4, an electric push rod 1006 is arranged inside one end of the limit ring 1005, and the end of the electric push rod 1006 is connected to the limit block 1007;

[0033] The specific operation is as follows: the limit ring 1005 will limit and block the end of the slide bar 1002, so that the block 1003 can support the bottom of the support plate 2, so that the biscuits can be placed in the groove outside the feeding tray 1, and the grooves outside the feeding tray 1 are respectively for loading, first detection, turning over, second detection, defective product removal and unloading stations. After the biscuits are placed on the support plate 2, the servo motor 603 can control the reciprocating screw 604 to rotate, so that the drive seat 605 moves down along the light rod 601, and the drive seat 605 will squeeze the drive column 905 to move it down. , so that the rack 904 contacts the driving gear 907, and the rotating seat 3 can be driven to rotate through the second damping shaft 906, the driven gear 908 and the ring gear 909, so as to automatically feed the biscuits on the outer end of the feeding tray 1, and when the feeding tray 1 rotates one sixth of a circle, the driving column 905 will drive the rack 904 to slide along the fixed rod 903 under the guidance of the inclined surface of the lower part of the limiting plate 901, so that the rack 904 is automatically separated from the driving gear 907, and at this time, the continuous rotation of the rotating seat 3 can be limited under the damping action of the second damping shaft 906, avoiding In order to avoid excessive rotation due to inertia, when the driving seat 605 moves up, the magnet 606 can absorb the iron driving column 905, thereby driving the rack 904, the fixed rod 903 and the slider 902 to move up together, and when the driving seat 605 moves to the inclined surface on the upper part of the limit plate 901, it will slide along the fixed rod 903 again and move to the top of the driving gear 907, so that in the process of reciprocating up and down movement, the feeding operation of the feeding tray 1 can be automatically controlled without adding an additional power source, and when the biscuits are conveyed to the top of the limit block 1007, Once a defective product is encountered, the electric push rod 1006 can be started through the controller to separate the limit block 1007 from the slide bar 1002, and the defective product can slide onto the conveyor belt below. Moreover, since the recessed portion of the limit ring 1005 corresponds exactly to the unloading position, when the feeding tray 1 moves the qualified product here, the return spring 1004 will push the slide bar 1002 under the limit of the fixed ear 1001, so that the stop block 1003 slides, and the support plate 2 will rotate to an inclined state, and the biscuits will slide along the support plate 2 to the conveyor belt below and be automatically unloaded.

[0034] In summary, when this reversible low-sugar biscuit defect detection device is used, first, the limit ring 1005 will limit and block the end of the sliding rod 1002, so that the block 1003 can support the bottom of the support plate 2, so that the biscuits can be placed in the groove outside the feeding tray 1, and the grooves outside the feeding tray 1 are respectively for loading, first detection, turning over, second detection, defective product rejection and unloading stations. Secondly, the biscuits are placed on the support plate 2 using an external loading device. At this time, the servo motor 603 can control the reciprocating screw 604 to rotate, so that the driving seat 605 moves down along the light rod 601, and the driving seat 605 will squeeze the driving column 905 to move it down, so that the rack 904 contacts the driving gear 907, and the second damping The rotating shaft 906, the driven gear 908 and the gear ring 909 drive the rotating seat 3 to rotate, and automatically feed the biscuits on the outer end of the feeding tray 1. After the feeding tray 1 rotates one-sixth of a circle, the driving column 905 will drive the rack 904 to slide along the fixed rod 903 under the guidance of the inclined surface of the lower part of the limiting plate 901, so that the rack 904 is automatically separated from the active gear 907. When the driving seat 605 moves up, the magnet 606 can absorb the iron driving column 905, thereby driving the rack 904, the fixed rod 903 and the slider 902 to move up together. When the driving seat 605 moves to the inclined surface on the upper part of the limiting plate 901, it will slide along the fixed rod 903 again and move to the top of the active gear 907. Then, the visual detector 5 will detect the lower The biscuit shooting detection is carried out on the other side. When the biscuit moves to the clamping assembly 7, the servo motor 603 can control the reciprocating screw 604 to rotate, so that the driving seat 605 moves up along the light rod 601. At this time, the compression spring 803 will press the lifting seat 802 against the convex ring in the middle of the lifting frame 801. Therefore, in the process of the driving seat 605 moving up, the guide block 701 can be pushed to move up along the guide rod 702, thereby driving the sliding column 703 to move horizontally, so that the driving plate 704 drives the sliding sleeve 705 to move to one end of the first damping shaft 706, so that the connecting rod 707 can push the clamping plate 708 to clamp the biscuit, and use the buffer pad 709 to avoid damaging the biscuit. After clamping, the first damping shaft 706 can be driven to move up, and the lifting seat 80 2 will squeeze the compression spring 803 to make it contract, thereby driving the biscuit to move up a certain distance, and then the ratchet 805 will contact the tooth plate 808. At this time, the pawl 804 and the ratchet 805 will slide, so that the biscuit will be automatically turned over while it rises. Then, when the driving seat 605 moves down, the inclined surface on the spring seat 807 will contact the inclined surface on the tooth plate 808, which can provide a certain horizontal component force to squeeze the spring seat 807. At the same time, the ratchet 805 will resist the teeth of the ratchet 805 to prevent the first damping shaft 706 from rotating. Therefore, slippage will occur between the tooth plate 808 and the ratchet 805, and when the driving seat 605 moves down and separates from the guide block 701, since the guide block 701 is heavier, it can pull the sliding column 703.Similarly, the clamping plate 708 can automatically release the biscuits. Finally, after the visual detector 5 detects the turned biscuits, the biscuits will be conveyed to the top of the limit block 1007. At this time, when a defective product is encountered, the electric push rod 1006 can be activated by the controller to separate the limit block 1007 from the slide bar 1002, and the defective product can slide to the conveyor belt below. Moreover, since the concave part of the limit ring 1005 just corresponds to the unloading station, when the feeding tray 1 moves the qualified product to this place, the reset spring 1004 will push the slide bar 1002 under the limit of the fixed ear 1001, so that the block 1003 slides, and the support plate 2 will rotate to an inclined state, and the biscuits will slide along the support plate 2 to the conveyor belt below for unloading.
