Abstract
Description
Technical Field
[0001] This invention relates to the field of automated testing equipment technology, and in particular to an integrated light inspection machine. Background Technology
[0002] On bottled product production lines, it is necessary to perform seal testing on bottled products after packaging to detect defects, damage, leakage, etc. Typically, the industry uses manual inspection, with inspectors visually inspecting samples. This method is inefficient, prone to omissions, and detrimental to controlling finished product quality. In recent years, some manufacturers have introduced automatic leak detection equipment for bottled products. However, this equipment can only test single-unit bottled products. Currently, an increasing number of plastic bottles on the market use a continuous plate structure, consisting of multiple bottles connected side-by-side. This structure differs significantly from single-unit bottles, making existing testing equipment unsuitable for leak detection in continuous plate bottled products. Summary of the Invention

The clamping mechanism of the rotary light inspection mechanism also includes a telescopic rod, a return spring, a slide rod, and a connecting rod structure. The telescopic rod is hinged to the gripper, and the connecting rod structure is rotatably mounted on the clamping mechanism. The clamping mechanism has a through hole that fits with the telescopic rod with a clearance.

[0019] The beneficial effects of this invention are as follows: This invention transports the continuous-plate bottled products fed by the feeding mechanism via a linear conveyor, while simultaneously performing multiple preliminary inspections by photographing the products at linear light inspection stations on both sides of the linear conveyor. Defective products initially found to be substandard are discharged along with the linear conveyor. Through the cooperation of a leakage distribution mechanism and a material transfer mechanism, the preliminarily qualified continuous-plate bottled products are sent to a rotary light inspection mechanism. The rotary feeding mechanism in the rotary light inspection mechanism transfers the continuous-plate bottled products one by one to a high rotary light inspection station for light inspection. After the light inspection is completed, the qualified products are stacked by a stacking and lifting mechanism, and the stacked continuous-plate bottled products are transported to the discharge mechanism by a discharge component, where the qualified products are discharged.

Detailed Implementation
[0032] To facilitate understanding of the present invention, the invention will be further described below with reference to the accompanying drawings.
[0033] In the description of this invention, it should be noted that the terms "front", "rear", "left", "right", "up", "down", "inner", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.
[0034] This invention is used for leak detection of plate-type bottled products, i.e., workpiece 900 below. Plate-type bottled products are composed of multiple plastic bottles connected side by side. Their structure is special compared to ordinary bottled products. Conventional transportation, clamping, and packaging methods are not suitable for plate-type bottled products. Therefore, this invention proposes a light inspection integrated machine specifically for leak detection of plate-type bottled products. Figure 1As shown, the integrated light inspection machine disclosed in this invention comprises a base 100, a feeding mechanism 200, a linear conveying mechanism 300, a leakage distribution mechanism 400, a material transfer mechanism, a rotary light inspection mechanism 500, a palletizing and lifting mechanism 600, and a discharging mechanism 700. The base 100 serves as the mounting foundation for this invention. The feeding mechanism 200, linear conveying mechanism 300, leakage distribution mechanism 400, material transfer mechanism, rotary light inspection mechanism 500, palletizing and lifting mechanism 600, and discharging mechanism 700 are all mounted on the base 100. The base 100 can be made of carbon steel to improve its strength. The feeding mechanism 200 is used to feed the workpiece 900. The feeding mechanism 200 can be the same mechanism used in conventional inspection equipment, which will not be described in detail here. The feeding mechanism 200 allows the workpiece 900 to enter the subsequent linear conveying mechanism 300 at a constant speed and spacing. The linear transport mechanism 300 can perform preliminary leak detection on the workpiece 900 while transporting it linearly. Defective products that fail the initial inspection are then discharged through the leak-prone product discharge channel 320 at the outlet of the linear transport mechanism 300. The leak-distribution mechanism 400, in conjunction with the material transfer mechanism, transfers the workpieces 900 that pass the initial inspection from the linear transport mechanism 300 to the rotary light inspection mechanism 500 one by one. The rotary light inspection mechanism 500 performs both the transfer and light inspection of the workpieces 900, moving workpieces 900 from lower positions to higher inspection positions for light inspection. Workpieces 900 that pass the light inspection are then transported to the stacking and lifting mechanism 600 via a discharge conveyor line located between the rotary light inspection mechanism 500 and the stacking and lifting mechanism 600. Workpieces 900 that fail the light inspection are discharged through the light inspection defective product discharge outlet 660 at the outlet of the discharge conveyor line. The palletizing and lifting mechanism 600 is used to palletize and transfer the workpieces 900 that have passed the light inspection. The palletizing and lifting mechanism 600 stacks the workpieces 900 that have passed the light inspection together so that multiple workpieces 900 are stacked together. Then, the entire stack of workpieces 900 is sent to the unloading mechanism 700, where the unloading mechanism 700 performs the final unloading work. The unloading mechanism 700 is the same as the feeding mechanism 200 and can be the same mechanism used in conventional inspection equipment.
[0035] like Figure 1 and Figure 2As shown, the linear conveying mechanism 300 used in this invention is positioned between the feeding mechanism 200 and the leakage distribution mechanism 400. Multiple linear light inspection stations 310 are sequentially arranged on both sides of the front half of the linear conveying mechanism 300. Each linear light inspection station 310 is equipped with an image acquisition component, which can be a photographic or video recording device. The linear light inspection stations 310 acquire images of the workpieces 900 transported one by one by the linear conveying mechanism 300, and then transmit the image information to the control system of the integrated light inspection machine for analysis to determine whether the corresponding workpiece 900 has a leakage. Since this invention does not involve improvements to the control system, they are not described in detail here; furthermore, the electrical boxes supplying power to the various mechanisms in this invention are also conventionally chosen and will not be described in detail here. The linear transport mechanism 300 comprises a support assembly 330, a linear guide rail 340, a transport chain 350, and a transport drive motor 360. The support assembly 330 serves as the mounting base for the linear transport mechanism 300, and the linear guide rail 340 is fixed to the base 100 via the support assembly 330. The transport drive motor 360 is fixed to the support assembly 330 and is connected to the transport chain 350 via transmission. Multiple spaced push rods 370 are fixed on the transport chain 350, and the linear guide rail 340 has a limiting groove extending along the length of the linear guide rail 340. The limiting groove and the push rod 370 are in clearance fit, allowing the push rod 370 to travel along the limiting groove under the drive of the transport chain 350. The transport drive motor 360 drives the transport chain 350 to rotate. The push rod 370 on the transport chain 350 moves together with the transport chain 350. The upper part of the push rod 370 extends upward from the limiting groove. The workpiece 900 on the linear guide rail 340 is pushed forward by the push rod 370, thereby realizing the linear transport of the workpiece 900.
[0036] like Figure 3As shown, the leakage dispensing mechanism 400 used in this invention consists of a dispensing mechanism bracket 410, a dispensing guide rail 420, and a dispensing sliding plate 430. The leakage dispensing mechanism 400 is fixed on the base 100 by the dispensing mechanism bracket 410, and the dispensing guide rail 420 and the dispensing sliding plate 430 are suspended above the outlet end of the linear conveying mechanism 300. A dispensing drive motor 440 is installed on the dispensing guide rail 420. The output end of the dispensing drive motor 440 is connected to the dispensing sliding plate 430 through a transmission structure. The dispensing drive motor 440 drives the dispensing sliding plate 430 to slide along the dispensing guide rail 420. When the linear conveyor 300 transports the pre-inspected qualified workpiece 900 to below the leakage distribution mechanism 400, the distribution drive motor 440 receives the sorting signal transmitted by the control system and starts to work, driving the distribution sliding plate 430 to move horizontally to both sides of the linear conveyor 300. During the horizontal movement, the distribution sliding plate 430 contacts the workpiece 900 on the linear conveyor 300, and the distribution sliding plate 430 pushes the workpiece 900 to detach it from the linear conveyor 300, thus separating the pre-inspected qualified workpiece from the pre-inspected unqualified workpiece.
[0037] In this invention, the workpiece 900 that passes the initial inspection is transferred through a material transfer mechanism located between the leakage distribution mechanism 400 and the rotary lamp inspection mechanism 500. As shown in Figure 4, the material transfer mechanism used in this invention consists of a slide rail 810, a lifting mechanism 820, and a lifting box 821. The slide rail 810 is used to transport the workpiece, i.e., the connecting plate workpiece 900, to the rotary lamp inspection mechanism 500. The slide rail 810 is a groove-shaped channel structure with a slide rail inlet and a slide rail outlet at both ends. The slide rail inlet is used for feeding the workpiece 900, and the slide rail outlet is used for discharging the workpiece 900. The slide rail 810 is inclined, and the slide rail outlet of the slide rail 810 is opposite to the top opening of the lifting box 821. Since the workpiece 900 is composed of multiple plastic bottles connected side by side, the workpiece 900 is basically in a flat position during the conveying process, making it inconvenient for the clamping mechanism 530 in the rotating light inspection mechanism 500 to grasp and hold the workpiece 900. To solve this problem, the present invention uses the cooperation of the slide rail 810 and the lifting box 821, employing a lifting box 821 with an open top, and positioning the lifting box 821 relative to the slide rail outlet of the slide rail 810. The lifting box 821 is a rectangular box. The dimensions of 821 are limited so that the inner width of the lifting box 821 is less than the length of the workpiece 900 when it is lying flat. When the workpiece 900 slides from the slide rail 810 into the lifting box 821, the workpiece 900 can only remain in an inclined position. At this time, the clamping mechanism 530 can grasp the workpiece 900. If the inner width of the lifting box 821 is further reduced so that the inner width of the lifting box 821 is slightly greater than the thickness of the workpiece 900, the workpiece 900 can basically remain upright in the lifting box 821.
[0038] Furthermore, to ensure that the workpiece 900 in the slide rail 810 can stably enter the lifting box 821, the structure of the lifting box 821 can be optimized so that the height of the side of the lifting box 821 near the slide rail 810 is lower than the height of the side away from the slide rail 810, and the height of the side of the lifting box 821 near the slide rail 810 is lower than the height of the slide rail exit of the slide rail 810. In addition, outwardly flared flanges can be provided on the top of both sides of the lifting box 821 to increase the length of the top opening of the lifting box 821, thereby increasing the size of the entrance of the lifting box 821, facilitating the entry of the workpiece 900 into the lifting box 821, while not affecting the limiting effect of the lifting box 821 on the workpiece 900. A certain distance needs to be reserved between the clamping mechanism 530 and the lifting box 821 to provide space for the clamping action of the clamping mechanism 530 and the sliding of the workpiece 900. Therefore, after the workpiece 900 enters the lifting box 821, the lifting box 821 needs to be moved to a height where the clamping mechanism 530 can clamp the workpiece 900. The lifting mechanism 820 is the mechanism designed to achieve the above functions. Figure 4 As shown, the lifting mechanism 820 includes a lifting cylinder 822, a lifting cylinder bracket 823, a lifting sensor 824, a pushing cylinder 825, a pushing cylinder bracket 826, and a pushing sensor 827. The lifting cylinder bracket 823 serves as the mounting and supporting foundation for the lifting mechanism 820. The lifting cylinder 822 is vertically fixed on the lifting cylinder bracket 823, and the piston rod of the lifting cylinder 822 is fixedly connected to the lifting box 821. When the lifting cylinder 822 operates, the piston extends, which drives the lifting box 821 fixed on the piston rod to rise vertically, so as to send the workpiece 900 in the lifting box 821 to the clamping mechanism 530 where it can be clamped. After the clamping mechanism 530 clamps the workpiece 900, the piston rod of the lifting cylinder 822 retracts, driving the empty lifting box 821 to descend back to its original position, waiting for the next workpiece 900 to be handed over. In this invention, a lifting sensor 824 monitors whether the workpiece 900 stably falls into the lifting box 821. Two lifting sensors 824 are fixed on the lifting cylinder bracket 823 and are positioned at the same horizontal level to ensure that the lifting sensors 824 can sense the lifting box 821. When the workpiece 900 in the lifting box 821 is tilted significantly, one of the lifting sensors 824 may fail to sense the workpiece 900, and then the lifting sensor 824 will issue an alarm signal. During the process of the workpiece 900 sliding from the slide rail 810 into the lifting box 821, there may be a situation where the slide rail 800 does not slide completely and stops at the slide rail exit. The pushing cylinder 825, the pushing cylinder bracket 826, and the pushing sensor 827 in this invention solve this problem. Figure 4As shown, the pusher mechanism bracket 826 serves as the mounting base for the pusher cylinder 825. The pusher cylinder 825 is mounted below the slide rail 810 via the pusher mechanism bracket 826. The angle of the pusher cylinder 825 is adjusted so that its piston rod points towards the slide rail outlet of the slide rail 810. Simultaneously, a push port 811 is provided at the slide rail outlet of the slide rail 810, through which the piston rod of the pusher cylinder 825 can pass. When the workpiece 900 stops at the slide rail outlet of the slide rail 810, the piston rod of the pusher cylinder 825 extends out of the push port 811 to push the workpiece 900, causing it to be pushed into the lifting box 821. Then, the piston rod of the pusher cylinder 825 retracts below the slide rail 810, without affecting the subsequent sliding of workpieces. Whether a workpiece 900 is stopped at the slide rail exit of the slide rail 810 is monitored by the pusher sensor 827. A monitoring port 812 is provided at the slide rail exit of the slide rail 810. The pusher sensor 827 is fixed on the bottom surface of the slide rail 810. The pusher sensor 827 determines whether a workpiece 900 is stopped at the slide rail exit of the slide rail 810 by whether the monitoring port 812 is blocked.
[0039] like Figure 1 , Figures 5 to 9 As shown, the rotary light inspection mechanism 500 used in this invention consists of multiple rotary light inspection stations 510 arranged on both sides of the rear half of the linear transport mechanism 300 and at least two sets of rotary feeding mechanisms 520 arranged on the same horizontal line of the rotary light inspection stations 510 on the same side. The rotary feeding mechanism 520 is provided with a rotatable clamping mechanism 530, which clamps the workpiece 900 through openable and retractable grippers 531. The rotary feeding mechanism 520 is equipped with a clamping mechanism 530 and a cam mechanism 540. The clamping mechanism 530 has grippers 531 for gripping the workpiece. The grippers 531 grip the workpiece 900 by opening and closing their own actions. The cam mechanism 540 limits the clamping mechanism 530. The limiting action between the cam mechanism 540 and the clamping mechanism 530 controls the opening of the grippers 531 on the clamping mechanism 530. When the clamping mechanism 530 is not limited by the cam mechanism 540, it remains in a closed state. This invention makes the clamping mechanisms 530 on all rotary feeding mechanisms 520 rotate synchronously and in the same direction. At the same time, the limiting directions of the cam mechanisms 540 on adjacent rotary feeding mechanisms 520 are opposite, so the grippers 531 of the clamping mechanisms 530 on adjacent rotary feeding mechanisms 520 alternately open and close their actions.
[0040] When transferring workpiece 900, the gripper 531 of the clamping mechanism 530 on the first rotary feeding mechanism 520 at the head of the rotary inspection mechanism 500 opens to grip workpiece 900. Then, the gripper 531 closes to clamp workpiece 900. The clamping mechanism 530 rotates to transfer workpiece 900 to the second rotary feeding mechanism 520. At this time, the clamping mechanism 530 of the first rotary feeding mechanism 520 is limited by the cam mechanism 540. The jaw 531 opens, and at the same time, the jaw 531 of the clamping mechanism 530 on the second rotary feeding mechanism 520 opens to clamp the workpiece 900. Then, it disengages under the limiting action of the corresponding cam mechanism 540. The jaw 531 of the clamping mechanism 530 on the second rotary feeding mechanism 520 closes to clamp the workpiece 900, and it is transferred with the rotation of the clamping mechanism 530 on the second rotary feeding mechanism 520. This cycle continues until the workpiece 900 is transferred to the rotary light inspection station 510 for light inspection and leak detection.
[0041] like Figure 6 and Figure 7 As shown, the rotary feeding mechanism 520 of this invention includes a rotary block 521 and a servo motor 522. The rotary block 521 serves as the mounting base for the rotary feeding mechanism 520, and the clamping mechanism 530 is mounted on the rotary block 521. The servo motor 522 serves as the driving component of the rotary block 521, and is connected to the rotary block 521 via a transmission connection. The servo motor 522 can be fixed by other mechanisms. The output end of the servo motor 522 is connected to the rotary block 521, preferably at the center of the rotary block 521. The operation of the servo motor 522 drives the rotary block 521 to rotate. The movement of the gripper 531 in the clamping mechanism 530 is directly controlled by the telescopic rod 532. The telescopic rod 532 is hinged to the gripper 531 via a linkage structure. This linkage structure is a commonly used transmission structure in the art and will not be described in detail here. Figures 7 to 9As shown, the telescopic rod 532 is telescopically mounted on the clamping mechanism 530. The telescopic rod 532, through its telescopic movement relative to the clamping mechanism 530, drives the connecting rod structure, thereby causing the gripper 531 to open or close. Specifically, the telescopic movement of the telescopic rod 532 in the clamping mechanism 530 is achieved by the cooperation of the return spring 533 and the slide rod 534. The clamping mechanism 530 has a through hole through which the telescopic rod 532 can pass. The diameter of this through hole is larger than the outer diameter of the telescopic rod 532 to allow a clearance fit between the through hole and the telescopic rod 532. One end of the telescopic rod 532 is hinged to the gripper 531 via a connecting rod structure, and the other end of the telescopic rod 532 is inserted into the through hole on the clamping mechanism 530. The return spring 533 is sleeved on the telescopic rod 532, and the slide rod 534 is fixed to the telescopic rod 532. One end of the return spring 533 is fixedly connected to the slide rod 534, and the other end of the return spring 533 abuts against the clamping mechanism 530. Applying force to the slide rod 534 causes the slide rod 534 to move the telescopic rod 532 toward the through hole, thus shortening the extended portion of the telescopic rod 532. As the telescopic rod 532 shortens, it drives the gripper 531 to open through the linkage structure, and the return spring 533 is compressed. Similarly, when no force is applied to the slide rod 534, the return spring 533 is no longer compressed and rebounds, causing the telescopic rod 532 to move toward the outside of the through hole, thus lengthening the extended portion of the telescopic rod 532. As the telescopic rod 532 lengthens, it drives the gripper 531 to close through the linkage structure.
[0042] In this invention, the automatic clamping and unloading of the workpiece 900 by the clamping mechanism 530 is achieved through the cooperation of the cam mechanism 540 and the telescopic rod 532. For example... Figure 7As shown, the cam mechanism 540 includes a cam cylinder 541 and a limiting arc plate 542. The cam cylinder 541 is fixed to the outside of the rotation path of the slide rod 534 by other mechanisms. The position of the cam cylinder 541 needs to ensure that the extended position of the output end of the cam cylinder 541 is within the rotation radius of the slide rod 534. When the slide rod 534 rotates with the clamping mechanism 530 to the same horizontal position as the cam cylinder 541, the output end of the cam cylinder 541 faces the slide rod 534 from the side. When the slide rod 534 rotates to contact and be compressed with the output end of the cam cylinder 541, the slide rod 534 drives the telescopic rod 532 to shorten, and the gripper 531 opens. The limiting arc plate 542 in the cam mechanism 540 cooperates with the cam cylinder 541. The limiting arc plate 542 is located outside the rotation path of the slide rod 534, and the inner diameter of the limiting arc plate 542 is smaller than the maximum rotation radius of the slide rod 534. The end of the limiting arc plate 542 is connected to the output end of the cam cylinder 541. After the slide rod 534 moves under the limiting action of the output end of the cam cylinder 541, it moves along the inner arc surface of the limiting arc plate 542. At this time, the slide rod 534 is continuously limited by the limiting arc plate 542, the return spring 533 remains compressed, and the gripper 531 is also in an open state. When the slide rod 534 slides off the limiting arc plate 542, the slide rod 534 is no longer limited by the limiting arc plate 542, the return spring 533 rebounds, and the gripper 531 is in a closed state.
[0043] To facilitate the transfer of workpieces between adjacent rotary feeding mechanisms 520, the limiting arc plate 542 can be a semi-circular arc plate so that the junction position of the workpieces between adjacent rotary feeding mechanisms 520 is exactly on the horizontal line. The limiting arc plates 542 on adjacent rotary feeding mechanisms 520 are respectively set in the upper half and lower half of the corresponding rotary feeding mechanism 520, and the concave surface of the limiting arc plate 542 faces the direction of the corresponding clamping mechanism 530, so that the opening and closing actions of the grippers 531 on the adjacent rotary feeding mechanisms 520 can be carried out alternately. Furthermore, considering that the sliding rod 534 is affected by the friction of the limiting arc plate 542 during its rotation along the limiting arc plate 542, in order to reduce the friction between the two, a bearing 535 can be sleeved on the sliding rod 534. The bearing 535 is located at the end of the sliding rod 534 that contacts the limiting arc plate 542, thereby converting the friction between the sliding rod 534 and the limiting arc plate 542 into rolling friction. The resistance experienced by the sliding rod 534 during its rotation is smaller, and the movement is more stable.
[0044] After the rotary light inspection mechanism 500 performs light inspection and leak detection on the workpiece 900, the workpiece 900 is transferred through the discharge conveyor line set between the rotary light inspection mechanism 500 and the palletizing and lifting mechanism 600. The outlet end of the discharge conveyor line is connected to the light inspection defective product discharge outlet 660. Workpieces 900 that fail the light inspection are discharged through the light inspection defective product discharge outlet 660, while workpieces 900 that pass the light inspection are stacked through the palletizing and lifting mechanism 600. Figure 10 and Figure 11 As shown, the palletizing lifting mechanism 600 used in this invention consists of a lifting mechanism 610, a material feeding mechanism 620, and a discharging assembly. A palletizing box 640 is mounted on the lifting mechanism 610. The palletizing box 640 can be raised and lowered vertically and has an inlet for passing through blister packs of bottled products. The material feeding mechanism 620 includes a belt drive assembly that drives a material feeding plate 621 to rotate, thereby feeding the workpiece 900 from the discharging conveyor line into the palletizing box 640. The material feeding mechanism 620 is located next to the lifting mechanism 610, and the belt drive assembly on the material feeding mechanism 620 is directly opposite the palletizing box 640 so that the material feeding plate 621 on the belt drive assembly is directly opposite the inlet of the palletizing box 640. The material feeding mechanism 620 is positioned directly above the discharge conveyor line. As the discharge conveyor line transports workpieces 900 one by one to the area below the material feeding mechanism 620, the material feeding plate 621, rotating with the belt drive assembly, moves the workpieces 900 on the discharge conveyor line toward the palletizing box 640. The workpieces 900 enter the palletizing box 640 from the inlet. Simultaneously, the lifting mechanism 610 controls the palletizing box 640 to rise upwards, and the material feeding plate 621 continues to feed the next workpiece 900 into the palletizing box 640. This cycle continues, and as the material feeding plate 621 feeds one workpiece at a time and the palletizing box 640 gradually rises, the workpieces 900 are neatly stacked in the palletizing box 640 to complete the palletizing work. After the palletizing box 640 is full of workpieces 900, the lifting mechanism 610 controls the palletizing box 640 to rise to the top of the lifting mechanism 610 for unloading and discharge. After unloading, the lifting mechanism 610 controls the palletizing box 640 to descend back to its original position for the next palletizing operation.
[0045] Specifically, the lifting mechanism 610 of the palletizing lifting mechanism 600 includes a lifting drive motor 611 and a lifting guide rail 612, such as... Figure 10 and Figure 11As shown, the lifting guide rail 612 is vertically arranged, and the lifting drive motor 611 is fixed to the top of the lifting guide rail 612. The palletizing box 640 is slidably engaged with the lifting guide rail 612, and the lifting and lowering action of the palletizing box 640 is controlled by the lifting drive motor 611. The lifting drive motor 611 is connected to the palletizing box 640 through a transmission component. Under the control of the lifting drive motor 611, the palletizing box 640 moves vertically up and down along the lifting guide rail 612. The palletizing box 640 is composed of a sliding plate 641 and a side plate 642 connected together. The sliding plate 641 is slidably engaged with the lifting guide rail 612. A side plate 642 is fixed on each side of the sliding plate 641. The side plates 642 are vertically fixed on the sliding plate 641 to form a semi-enclosed structure that limits the workpiece 900 from both sides. The top, front and bottom surfaces of the palletizing box 640 are not closed. The opening on the front of the palletizing box 640 is the feed port. Multiple partition plates 643 are fixed on the opposite surfaces of the two side plates 642 of the palletizing box 640. The partition plates 643 on each side plate 642 are horizontally arranged and evenly distributed along the height direction of the side plate 642, and the partition plates 643 on the two side plates 642 correspond one-to-one. By setting the partition plates 643 as supporting components for the workpieces 900 inside the palletizing box 640, the partition plates 643 can also make the workpieces 900 stack neatly inside the palletizing box 640. Furthermore, in order to prevent the workpieces 900 from sliding out of the palletizing box 640 during the rising process, the structure of the partition plates 643 can be optimized. The ends of the partition plates 643 are thickened to form limiting bosses at the ends of the partition plates 643. The limiting bosses can then limit the workpieces 900 in the palletizing box 640 to prevent them from detaching from the palletizing box 640.
[0046] Specifically, the sliding engagement between the palletizing box 640 and the lifting guide rail 612 is achieved by the guide rail groove 613 provided on the lifting guide rail 612 and the limiting flange provided on the sliding plate 641. For example... Figure 11 As shown, guide rail grooves 613 are provided on both sides of the lifting guide rail 612. The guide rail grooves 613 extend along the height direction of the lifting guide rail 612. The two sides of the sliding plate 641 are bent to form limiting folds that insert into the corresponding guide rail grooves 613. These limiting folds and the guide rail grooves 613 form a limiting fit. Under the drive of the lifting drive motor 611, the palletizing box 640 can achieve vertical lifting and lowering movement by sliding along the lifting guide rail 612.
[0047] like Figure 10As shown, the belt drive assembly used in the feeding mechanism 620 of this invention consists of a mounting plate 631, a feeding drive motor 632, a belt 633, a drive pulley 634, and two driven pulleys 635. The drive pulley 634 is connected to the output end of the feeding drive motor 632. The two driven pulleys 635 are rotatably mounted on the mounting plate 631 and form a triangular distribution with the drive pulley 634. The belt 633 is sleeved on the drive pulley 634 and the two driven pulleys 635. The feeding plate 621 is vertically fixed on the outer surface of the belt 633. The feeding drive motor 632 drives the drive pulley 634 to rotate. During the rotation of the drive pulley 634, the belt 633 moves. The driven pulleys 635 support the belt 633 while assisting in promoting the movement of the belt 633, thereby causing the feeding plate 621 to rotate and move the blister packs of bottled products on the conveyor belt. To ensure the stability of the belt 633's movement and prevent the belt 633 from deviating, as follows... Figure 10 As shown, in this invention, a baffle 636 is added to the drive wheel 634. A baffle 636 is fixed at each end of the drive wheel 634. The outer diameter of the baffle 636 is larger than the outer diameter of the drive wheel 634. The belt 633 is located between the two baffles 636. The two baffles 636 and the belt 633 form a limiting fit to ensure the stable movement of the belt 633.
[0048] When the palletizing box 640, carrying a stack of workpieces 900, rises to the top of the lifting mechanism 610, the workpieces 900 inside the palletizing box 640 are unloaded and discharged through the unloading assembly. Figure 10 As shown, the discharge assembly includes a discharge guide rail 651 and a discharge plate 652. The discharge guide rail 651 is horizontally mounted on the side of the lifting guide rail 612 and suspended in the air via an installation structure. The discharge plate 652 is mounted on the discharge guide rail 651 via a transmission mechanism so that the discharge plate 652 can slide back and forth along the discharge guide rail 651 in the horizontal direction. The discharge plate 652 is vertically mounted and located in front of the lifting guide rail 612, and the discharge plate 652 is directly opposite the top opening of the palletizing box 640 in the vertical direction. When the palletizing box 640 rises along the lifting guide rail 612 to the upper part of the lifting mechanism 610, the unloading plate 652 is inserted into the palletizing box 640, and the unloading plate 652 is positioned between the workpiece 900 and the sliding plate 641 inside the palletizing box 640; then the unloading plate 652 moves forward along the discharge guide rail 651, and the unloading plate 652 smoothly pushes the workpiece 900 inside the palletizing box 640 forward until the stacked workpiece 900 is completely removed, thereby realizing the unloading and discharge work; after unloading, the palletizing box 640 descends back to its original position under the drive of the lifting drive motor 611 to carry out the next palletizing work, while the unloading plate 652 also moves backward back to its original position to wait for the next unloading work.
[0049] The palletizing lifting mechanism 600 transports the entire stack of workpieces 900 to the unloading mechanism 700 via the unloading component, and finally the unloading mechanism 700 unloads the qualified products.
