Description

Technical Field

[0001] This utility model relates to the field of overlock technology, and specifically to a vision positioning and feeding device for intelligent overlock machines. Background Technology

[0002] The current edge-sealing process for products such as armbands and shoulder patches is all done manually. During manual operation, there is no precise fixed position for edge sealing, resulting in poor edge uniformity and an unattractive appearance after the product is finished. Because it relies entirely on manual operation, the processing cost is high, the processing steps are cumbersome, the labor intensity is high, and the work efficiency is low, which does not meet the needs of automated production advocated by today's society.

[0003] Chinese utility model patent ZL202223530744.3 discloses a double-material feeding and conveying device for an edge banding machine. This device includes a first and a second feeding mechanism, and a conveying mechanism located between the first and second feeding mechanisms to alternately transport the products to be edged from the first and second feeding mechanisms. The conveying mechanism includes a first and a second conveying frame, a first lifting module mounted at the front end of the first conveying frame, a first positioning component mounted at the lower end of the first lifting module for positioning the products to be edged from the first feeding mechanism, a second lifting module mounted at the front end of the second conveying frame, a second positioning component mounted at the lower end of the second lifting module for positioning the products to be edged from the second feeding mechanism, and a rotary drive module for driving the first and second conveying frames to rotate synchronously. When the first conveying frame, in conjunction with the first positioning component, transports the products to be edged from the first feeding mechanism, the second conveying frame, in conjunction with the second positioning component, picks up and positions the products to be edged from the second feeding mechanism.

[0004] The aforementioned dual-feeding and conveying device only uses the first and second feeding mechanisms to store the products to be edged and to feed the products to be edged. Then, the conveying mechanism alternately transports the products to be edged fed by the first and second feeding mechanisms out. It does not use visual positioning, so it cannot confirm the starting point of the products to be edged, nor can it adjust the starting point of all the products to be edged to a uniform position. As a result, after the edge-sealing machine stitches the products to be edged, the different starting points lead to inconsistent product quality or poor quality.

[0005] In view of the above, the inventors propose the following technical solution. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a visual positioning and feeding device for intelligent overlock machines.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The visual positioning and feeding device for the intelligent overlock machine includes a storage mechanism installed on the side of the machine base for storing products to be overlocked, a feeding mechanism for lifting the products to be overlocked in the storage mechanism to achieve feeding, and a conveying mechanism for picking up and transporting the products to be overlocked at the top of the storage mechanism to the worktable. Above the storage mechanism is a visual positioning mechanism for taking pictures of the products to be overlocked at the top of the storage mechanism to determine the starting point of the stitch. Furthermore, a rotation drive module is provided on the outside of the storage mechanism or the outside of the machine base for driving the products to be overlocked at the top of the storage mechanism to rotate so that their starting points are in the same position.

The lifting plate is placed in the storage space and located above the bottom plate.

[0010] Furthermore, in the above technical solution, the lifting drive module includes a vertically installed first stand, a first lead screw installed in the first stand, a first lifting seat installed on the first lead screw, and a first servo motor for driving the first lead screw to rotate. The lifting plate is installed on the first lifting seat; the sensing module is installed on the upper end of the first stand.

[0011] Furthermore, in the above technical solution, the sensing module includes a mounting frame that is installed on the upper end of the first stand in an adjustable relative position and is in the shape of a semi-square frame, and a first sensor and a second sensor that are installed at both ends of the mounting frame and are corresponding to each other. The mounting frame surrounds the outer side of the upper end of the storage mechanism, and the first sensor and the second sensor are located outside the upper end of the storage mechanism on both sides.

[0012] Furthermore, in the above technical solution, the rotary drive module includes a first upright frame installed on the outside of the storage mechanism or the outside of the base, a motor installed on the upper end of the first upright frame and vertically distributed, and a brush wheel installed on the rotating shaft at the upper end of the motor. The outer side of the brush wheel extends into the storage mechanism and contacts the outer surface of the product to be locked at the uppermost end of the storage mechanism.

[0013] Furthermore, in the above technical solution, the visual positioning mechanism includes a second upright mounted on the base, an annular light source mounted on the upper end of the second upright and adjustable in front and back position, and a visual camera mounted on the upper end of the second upright and located above the annular light source and adjustable in front and back and up and down position. Both the annular light source and the visual camera are located above the material storage mechanism.

[0014] Furthermore, in the above technical solution, the annular light source is fixed to a horizontal adjustment plate. A first strip-shaped adjustment hole is provided on one side of the horizontal adjustment plate. The annular light source is installed on an L-shaped adjustment plate in an adjustable manner. A second strip-shaped adjustment hole is provided on one side of the lower end of the L-shaped adjustment plate. The horizontal adjustment plate is attached to the second upright, and the lower end of the L-shaped adjustment plate is attached to the horizontal adjustment plate. The second strip-shaped adjustment hole corresponds to the first strip-shaped adjustment hole. Several first screws pass through the second strip-shaped adjustment hole and the first strip-shaped adjustment hole and are screwed to the upper end of the second upright to form an adjustable assembly structure, thereby fixing the L-shaped adjustment plate and the horizontal adjustment plate to the upper end of the second upright.

[0015] Furthermore, in the above technical solution, the upper end of the L-shaped adjustment plate is provided with several vertically distributed third strip-shaped adjustment holes, and the second screw passes through the third strip-shaped adjustment holes and is screw-fixed to the vision camera to form an adjustable assembly structure.

[0017] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: When the present invention is working, the vision positioning mechanism is used to take pictures of the products to be edged at the top of the storage mechanism to determine the starting point. When it is found that the starting points of the products to be edged are not in the same position, the rotation drive module is controlled to work. The rotation drive module drives the products to be edged at the top of the storage mechanism to rotate in order to adjust the relative position of the products to be edged until the starting points of the products to be edged are in the same position. The rotation drive module stops driving the products to be edged to rotate, and the vision positioning mechanism is used again to take pictures of the products to be edged to determine the starting point. Finally, the conveying mechanism picks up the products to be edged at the top of the storage mechanism and conveys them to the worktable to facilitate the subsequent edge-locking work. It can also ensure that the starting point of the edge-locking of each product is in the same position, ensuring that the quality of each product is uniform and that the quality of each product is excellent.

[0027] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0028] See Figure 1-9 The image shows an intelligent overlock machine equipped with the visual positioning feeding device of this invention. It includes a base 1, a worktable 2 mounted on the base 1 for supporting the product to be overlocked, a machine head 3 located beside the worktable 2 for overlocking the product, needle plate teeth 4 mounted on the worktable 2, and presser feet 5 adapted to the needle plate teeth 4. In operation, the product to be overlocked is placed on the worktable 2 and positioned on top of the needle plate teeth 4. The presser feet 5 then hold the product in place. The machine head 3 then operates to overlock the edges of the product, while the needle plate teeth 4 cooperate to move the product, continuously overlocking the edges. This is the working process of a conventional overlock machine and represents conventional technology.

[0029] The base 1 is also provided with an auxiliary edge-locking device 6. The auxiliary edge-locking device 6 includes a swing seat 61 mounted on the base 1 in a swingable manner, a first drive mechanism 62 for driving the swing seat 61 to swing, a transverse drive mechanism 63 mounted on the swing seat 61, a transverse moving frame 64 mounted on the transverse drive mechanism 63, a pressure arm 65 mounted on the transverse moving frame 64, and a pressure roller 66 mounted at the end of the pressure arm 65 and distributed in a vertical direction, a detection module 67 located on the side of the workbench 2 for detecting the position of the outer edge of the product to be edged, and a second drive mechanism 68 for cooperating with the detection module 67 to control the pressure roller 66 to rotate clockwise / counterclockwise. The pressure roller 66 is located on the side of the pressure foot 5 and is used to press the product to be edged so as to cooperate with the needle plate teeth 4 to control the movement direction of the product to be edged.

[0030] The auxiliary overlocking device 6 plays an auxiliary role when the overlocking machine is overlocking the product to be overlocked. Specifically, the product to be overlocked is placed on the worktable 2 and placed on the upper end of the needle plate teeth 4. The presser foot 5 presses down on the product to be overlocked. At the same time, the first drive mechanism 62 of the auxiliary overlocking device 6 drives the swing seat 61, which in turn drives the press arm 65 to press down, thereby pressing the press roller 66 to press down on the product to be overlocked, so that the product to be overlocked is in close contact with the worktable 2. The detection module 67 detects the position of the outer edge of the product to be overlocked in real time, determines that the outer edge of the product to be overlocked is in the optimal position, ensures that the spacing of the overlocking is equal in the later stage, and thus ensures the quality of overlocking. Subsequently, the machine head 3 works to sew the edge of the product to be overlocked, and the needle plate teeth 4 cooperate to drive the product to be overlocked to move. At the same time, the second drive mechanism 68 drives the pressure roller 66 to rotate, thereby assisting the needle plate teeth 4 in driving the product to be overlocked to move. Thus, the pressure roller 66 not only presses down on the product to be overlocked to prevent local bulging and other defects during the overlocking process, but also assists the needle plate teeth 4 in driving the product to be overlocked to move, thereby controlling the direction of the overlocking stitch. It does not require manual operation, reduces labor intensity, avoids hand injuries, and ensures that the stitch direction of the product to be overlocked is always in the optimal direction, ensuring the quality of the overlocking / overlocking of the product. When overlocking the convex edge of the product to be overlocked, the detection module 67 detects that the outer edge of the product to be overlocked is a convex edge, and controls the second drive mechanism 68 to drive the pressure roller 66 to rotate counterclockwise. At the same time, the auxiliary needle plate teeth 4 continue to drive the product to be overlocked from front to back, and control the rotation speed of the pressure roller 66, thereby driving the product to be overlocked to turn, so that the machine head always sews at equidistant positions on the outer edge of the product to be overlocked to achieve equidistant binding / overlocking. Similarly, when overlocking the concave edge of the product to be overlocked, the detection module 67 detects that the outer edge of the product to be overlocked is a convex edge. The outer edge of the product is concave. The second drive mechanism 68 drives the pressure roller 66 to rotate clockwise. At the same time, the auxiliary needle plate teeth 4 continue to drive the product to be edged from front to back and control the rotation speed of the pressure roller 66. This allows the product to be edged to turn, so that the machine head always sews at equidistant positions on the outer edge of the product to be edged to achieve equidistant binding / locking. This ensures that the stitching direction of the product to be edged is always in the optimal direction and there will be no crooked stitching, thus ensuring the binding / locking quality of the product to be edged.

[0031] The function of the transverse drive mechanism 63 is to drive the pressure arm 65 and the pressure roller 66 at its lower end to move outward, thereby driving the product pressed by the pressure roller 66 and completed with the edge locking to move outward, so that the product with the edge locking is removed from the needle plate teeth 4, which facilitates the subsequent cutting and blanking of the product with the edge locking, and also provides enough space for the next product to be edge locked for edge locking processing.

[0032] A support column 11 is provided on the base 1, and the swing seat 61 is mounted on the support column 11 in a swingable manner through a hinge 611. Its assembly structure is simple. The hinge 611 can be a hinge or the like. A wire cutting module 21 is provided at the front end of the workbench 2. When the lateral drive mechanism 63 drives the pressure arm 65 and the pressure roller 66 at its lower end to move outward, the finished edge-locking product is moved outward. The lateral drive mechanism 63 also drives the pressure arm 65 and the pressure roller 66 at its lower end to reset. After the machine head performs stitching on the next product to be edge-locked, the stitching of the finished edge-locking product is still connected to the product to be edge-locked. As the product to be edge-locked rotates, the finished edge-locking product rotates along with the stitching and falls below the front end of the worktable 2. The stitching is straightened and falls into the thread-cutting module 21. The thread-cutting module 21 cuts the stitching, causing the finished edge-locking product to fall into the discharge hopper 10. The discharge hopper 10 is located on the lower side of the front end of the worktable 2 and below the thread-cutting module 21 to receive the finished edge-locking product.

[0033] The structure of the detection module 67 is described in detail below:

[0034] The detection module 67 includes a detection swing arm 671 mounted oscillatingly on the side of the workbench 2 for contacting the outer edge of the product to be edged, and a sensor 672 mounted on the upper end of the detection swing arm 671 for detecting the swing amplitude of the detection swing arm 671. During operation, when the product to be edged is in contact with the lower end of the detection swing arm 671, and the edge of the product shifts, the product will push the detection swing arm 671 to swing. At this time, the sensor 672 detects the swing amplitude of the detection swing arm 671, and then controls the rotation direction and speed of the second drive mechanism 68 driving the pressure roller 66. This assists the needle plate teeth 4 in driving the product to change its direction of movement, thereby adjusting the stitch direction of the product to be edged to always be in the optimal direction, so that the machine head always sews at equidistant positions on the outer edge of the product to achieve equidistant edge binding / locking.

[0035] Specifically, a swing shaft 673 is fixed in the middle of the detection swing rod 671. The swing shaft 673 is installed in the connecting block 674 in a swingable manner, and the connecting block 674 is fixed on the machine head 3. The connecting block 674 also has a swing groove 675 that runs through the upper and lower end faces and the side. The detection swing rod 671 is placed in the swing groove 675 and can swing in the swing groove 675 to ensure that the swing direction is in one direction and avoid deviation. The sensor 672 is installed on the machine head 3 in an adjustable relative position through a mounting bracket 676. The relative position of the sensor 672 can be adjusted by the mounting bracket 676 to improve the detection quality. A detection block 677 is also provided at the upper end of the detection swing rod 671. The detection block 677 is located next to the sensor 672. The sensor 672 can be a photoelectric sensor or the like. The detection block 677 is used to reflect the light emitted by the sensor 672, and the sensor 672 receives the reflected light to calculate the offset of the swing arm 671. This is a conventional technology and will not be described in detail here.

[0036] The detection block 677 is provided with a through hole 601 that passes through the upper and lower ends. The side of the detection block 677 is provided with a transverse screw hole 602 that passes through the through hole 601. The detection block 677 is sleeved on the upper end of the detection swing rod 671 through the through hole 601. The first screw spirals through the transverse screw hole 602 and presses against the outer side of the upper end of the detection swing rod 671 to fix the detection block 677 to the upper end of the detection swing rod 671. Its assembly structure is simple, its installation is convenient, and it is easy to adjust and maintain.

[0037] The first drive mechanism 62 is fixed to the base 1. The upper end of the first drive rod 621 of the first drive mechanism 62 is rotatably connected to the swing seat 61. The first drive mechanism 62 is an electric push rod, a pneumatic cylinder, or a hydraulic cylinder. In this embodiment, the first drive mechanism 62 is a pneumatic cylinder, which has a simple structure and low cost.

[0038] The lateral drive mechanism 63 includes a lateral slide rail 631 mounted on a swing base 61, a lateral slider 632 sleeved on the lateral slide rail 631, a threaded sleeve disposed in the lateral slider 632, a lead screw 633 passing through the threaded sleeve, and a servo motor 634 mounted on the swing base 61 for driving the lead screw 633 to rotate. The lateral moving frame 64 is fixed to the lateral slider 632. The lateral drive mechanism 63 has a simple structure and can accurately drive the lateral moving frame 64 to move laterally.

[0039] The second drive mechanism 68 may include at least two of the above structures:

[0040] The first structure is: combination Figure 6As shown, the second drive mechanism 68 includes a first drive wheel 681 and a second drive wheel 682 disposed at the upper and lower ends of the pressure arm 65, a transmission component 683 connected between the first drive wheel 681 and the second drive wheel 682, and a motor 684 mounted on the transverse moving frame 64 for driving the first drive wheel 681 to rotate. The first drive wheel 681 and the second drive wheel 682 are pulleys, and the transmission component 683 is a belt; alternatively, the first drive wheel 681 and the second drive wheel 682 are gears, and the transmission component 683 is a chain.

[0041] The second structure is as follows: the second drive mechanism 68 includes a motor disposed at the lower end of the pressure arm 65, and the rotating shaft of the motor is connected to the pressure roller 66 to drive the pressure roller 66 to rotate.

[0042] The pressure arm 65 includes a first arm body 651 and a second arm body 652 with adjustable relative positions. The upper end of the second arm body 652 is provided with a strip hole 603, and the lower end of the first arm body 651 is provided with a first screw hole 604. A second screw passes through the strip hole 603 and is screwed into the first screw hole 604 for fixation. Its assembly structure is simple, and the length of the entire pressure arm 65 is adjustable, which facilitates the adjustment of the pressure roller's pressing height.

[0043] This utility model also adds a visual positioning feeding device 7, which includes a storage mechanism 71 installed on the side of the machine base 1 for storing products to be edged, a feeding mechanism 72 for lifting the products to be edged in the storage mechanism 71 to achieve feeding, and a conveying mechanism 73 for picking up and transporting the products to be edged at the top of the storage mechanism 71 to the worktable 2. When the visual positioning feeding device 7 is working, the storage mechanism 71 stores multiple products to be edged, the feeding mechanism 72 lifts the products to be edged in the storage mechanism 71 to achieve feeding, and finally the conveying mechanism 73 picks up and transports the products to be edged at the top of the storage mechanism 71 to the worktable 2, and places them on the upper end of the needle plate teeth 4. Then the presser foot 5 presses down the products to be edged, and then the machine head 3 works to sew the edges of the products to be edged, and the needle plate teeth 4 cooperate to drive the products to be edged to move, so as to continuously sew the edges of the products to be edged.

[0044] The visual positioning feeding device 7 of this utility model has made the following improvements: a visual positioning mechanism 9 is provided above the storage mechanism 71 for taking pictures of the product to be edged at the top of the storage mechanism 71 to determine the starting point of the stitching, and a rotary drive module 8 is provided on the outside of the storage mechanism 71 or the outside of the machine base 1 for driving the product to be edged at the top of the storage mechanism 71 to rotate so as to adjust its starting point to be in the same position. During operation, the vision positioning mechanism 9 takes a picture of the topmost product to be edged in the storage mechanism 71 to determine the starting point of the stitch. When it is found that the starting points of the products to be edged are not in the same position, the rotation drive module 8 is controlled to work. The rotation drive module 8 drives the topmost product to be edged in the storage mechanism 71 to rotate to adjust the relative position of the products to be edged until the starting points of the products to be edged are in the same position. The rotation drive module 8 stops driving the product to be edged to rotate, and the vision positioning mechanism 9 takes a picture of the product to be edged again to determine the starting point of the stitch. Finally, the conveying mechanism 73 picks up the topmost product to be edged in the storage mechanism 71 and conveys it to the worktable 2 to facilitate the subsequent edge-locking work and ensure that the starting point of the edge-locking of each product is in the same position, ensuring that the quality of each product is uniform and excellent.

[0045] The starting point for overlocking can be determined as follows: the product to be overlocked is an armband with various patterns, and a particular pattern is used as the starting point.

[0046] The storage mechanism 71 includes a base plate 711 and multiple limiting rods 712 fixed on the base plate 711. A storage space is formed between the base plate 711 and the limiting rods 712 for stacking products to be edged and limiting the products to be edged. Its structure is extremely simple.

[0047] The feeding mechanism 72 includes a lifting drive module 721 installed on the outside of the storage mechanism 71, a lifting plate 722 installed on the lifting drive module 721 and driven by the lifting drive module 721 to achieve lifting, and a sensing module 723 installed on the upper end of the lifting drive module 721 for detecting whether the product to be edged has risen to a predetermined position. The lifting plate 722 is placed in the storage space and located above the base plate 711, and its structure is extremely simple. The lifting drive module 721 includes a vertically installed first stand 701, a first lead screw 702 installed in the first stand 701, a first lifting seat 703 installed on the first lead screw 702, and a first servo motor 704 for driving the first lead screw 702 to rotate. The lifting plate 722 is installed on the first lifting seat 703; the sensing module 723 is installed on the upper end of the first stand 701.

[0048] The sensing module 723 includes a mounting frame 705, which is mounted on the upper end of the first stand 701 in an adjustable relative position and is in the shape of a semi-square frame. A first sensor 706 and a second sensor 707 are mounted on both ends of the mounting frame 705 and are corresponding to each other. The mounting frame 705 surrounds the outer side of the upper end of the storage mechanism 71, and the first sensor 706 and the second sensor 707 are located outside the upper end of the storage mechanism 71 on both sides. One of the first sensor 706 and the second sensor 707 is a transmitter and the other is a receiver. It can detect whether the product to be locked at the uppermost position has risen to a predetermined position. If it has risen to the predetermined position, it controls the visual positioning mechanism 9 to work.

[0049] The rotary drive module 8 includes a first upright 81 mounted on the outside of the storage mechanism 71 or the outside of the base 1, a motor 82 mounted on the upper end of the first upright 81 and vertically distributed, and a brush wheel 83 mounted on the rotating shaft of the upper end of the motor 82. The outer side of the brush wheel 83 extends into the storage mechanism 71 and contacts the outer surface of the product to be edged at the uppermost end of the storage mechanism 71. During operation, the motor 82 drives the brush wheel 83 to rotate, and the bristles on the outer surface of the brush wheel 83 rotate and rub against the outer edge surface of the product to be edged, thereby driving the product to rotate and facilitating the positioning of the starting point of the edge-locking process at a predetermined position. The rotary drive module 8 has a very simple structure and can smoothly drive the product to rotate.

[0050] The visual positioning mechanism 9 includes a second stand 91 mounted on the base 1, an annular light source 92 mounted on the upper end of the second stand 91 and adjustable in front and back position, and a visual camera 93 mounted on the upper end of the second stand 91 and located above the annular light source 92 and adjustable in front and back and up and down position. Both the annular light source 92 and the visual camera 93 are located above the material storage mechanism 71.

[0051] The ring light source 92 is fixed to a horizontal adjustment plate 94. A first strip-shaped adjustment hole 941 is provided on one side of the horizontal adjustment plate 94. The ring light source 92 is mounted on an L-shaped adjustment plate 95 with adjustable vertical position. A second strip-shaped adjustment hole 951 is provided on one side of the lower end of the L-shaped adjustment plate 95. The horizontal adjustment plate 94 is attached to a second upright 91, and the lower end of the L-shaped adjustment plate 95 is attached to the horizontal adjustment plate 94. The second strip-shaped adjustment hole 951 corresponds to the first strip-shaped adjustment hole 941. Several first screws pass through the second strip-shaped adjustment hole 951 and the first strip-shaped adjustment hole 941. The first screw is screwed to the upper end of the second support 91 to form an adjustable assembly structure. The L-shaped adjustment plate 95 and the horizontal adjustment plate 94 are fixed to the upper end of the second support 91. The assembly structure is simple. When it is necessary to adjust the relative position of the ring light source 92 and the vision camera 93, it is only necessary to loosen the first screw to adjust the horizontal adjustment plate 94 and the L-shaped adjustment plate 95 relative to the upper end of the second support 91 to adjust the horizontal position, thereby adjusting the relative position of the ring light source 92 and the vision camera 93. After completion, the first screw can be tightened directly. The operation is extremely simple, with few steps and convenient implementation.

[0052] The upper end of the L-shaped adjustment plate 95 is provided with several vertically distributed third strip-shaped adjustment holes 952. The second screw passes through the third strip-shaped adjustment holes 952 and is screw-fixed to the vision camera 93 to form an adjustable assembly structure, which is used to adjust the vertical position of the vision camera 93.

[0053] The conveying mechanism 73 includes a rotary cylinder 732 mounted on the base 1 at an adjustable height via an adjusting member 731, a lifting cylinder 733 mounted on the upper end of the rotary cylinder 732 and driven by the rotary cylinder 732 to rotate, a conveying frame 734 mounted on the lifting cylinder 733 and driven by the lifting cylinder 733 to achieve lifting, and a pickup member 735 mounted on the lower side of the end of the conveying frame 734, wherein the pickup member 735 is a clamp or a vacuum suction cup; the entire conveying mechanism 73 has a simple structure, and the lifting cylinder 733 drives the conveying frame 734 and... The pickup component 735 at its end descends to pick up the product to be edged at the top, and the lifting cylinder 733 drives the transport frame 734 and its pickup component 735 at its end to rise to drive the product to be edged at the top away from the storage mechanism 71. Then, the rotary cylinder 732 drives the lifting cylinder 733, the transport frame 734 and its pickup component 735 at its end to rotate to transport the product to be edged above the worktable. Then, the lifting cylinder 733 drives the transport frame 734 and its pickup component 735 at its end to descend to place the product to be edged on the worktable to realize the transport function.

[0054] The lifting cylinder 733 includes a cylinder body 708, a piston rod installed at the lower end of the cylinder body 708, and a lifting block 709 at the lower end of the piston rod. The lifting block 709 is installed with the rotary cylinder 732. The outer side of the upper end of the cylinder body 708 is fixedly installed with the transport frame 734. Its assembly structure is simple, and the cylinder body 708 has enough space for installation with the transport frame 734, so that the lifting block 709 can be installed with the rotary cylinder 732 even though the size is small.

[0055] In summary, during operation, the visual positioning mechanism 9 takes a picture of the topmost product to be edged in the storage mechanism 71 to determine the starting point. When the starting points of the products to be edged are not in the same position, the rotary drive module 8 is controlled to rotate, thereby adjusting the relative position of the products to be edged until the starting points are in the same position. The rotary drive module 8 then stops rotating the products to be edged, and the visual positioning mechanism 9 takes another picture of the products to be edged to determine the starting point. Finally, the conveying mechanism 73 picks up the topmost product to be edged in the storage mechanism 71 and moves it to the worktable 2 for subsequent edge-locking work. This ensures that the starting point of each product is in the same position, guaranteeing consistent and high-quality products.
