Description

TECHNICAL FIELD

[0001] The present application relates to the field of detection equipment, in particular to a finished product detection marking equipment. BACKGROUND

[0002] The inkjet printer is a high-tech product that uses charged ink particles deflected by a high-voltage electric field to print patterns, characters and numbers on various surfaces. It is widely used in the food industry, cosmetics industry, pharmaceutical industry, automobile parts processing industry, wire and cable industry, aluminum plastic pipe industry, tobacco and liquor industry and other fields. It can be used on different carriers such as paper, plastic, metal and glass, and can achieve good printing effect on both hard and soft surfaces.

[0003] However, during actual production, a small number of printed products may have color block overlap and color block misalignment, resulting in the production of defective products. Enterprises usually customize printed products for customers, and the same detection equipment cannot adapt to the detection of different specifications of printed products. When different printed products are placed on the same equipment, they may slip, misalign or fold due to the size matching between the equipment and the printed products, resulting in low detection accuracy, and even damage to the printed products during detection. SUMMARY

[0004] In order to adapt to the detection and marking of printed products of different sizes, the present application provides a finished product detection marking equipment.

[0005] The finished product detection marking equipment provided by the present application adopts the following technical scheme:

[0011] By adopting the above technical scheme, when the driving gear rotates, the first rack can move in opposite directions at the same time, so as to adjust the distance between the two guide assemblies, so that the two guide assemblies can abut against the two sides of the composite film at the same time, and the composite film of different sizes can be limited, thereby reducing the risk of deviation of the composite film, so that the composite film can pass below the detecting mechanism, thereby improving the recognition accuracy of the detecting mechanism on the composite film and avoiding the situation that the detecting mechanism does not recognize the composite film completely.

[0012] Optionally, the guide assembly comprises an elastic limiting piece and a roller, the first rack and the second rack are rotationally connected with a roller respectively, one end of the elastic limiting piece is connected with the rotating shaft of the roller, and the other end abuts against the surface of the workbench, and is used for clamping the composite film located on the surface of the workbench.

[0013] By adopting the above technical scheme, the two rollers can abut against the two sides of the composite film, thereby reducing the risk of deviation of the composite film during movement, the elastic limiting piece enables the composite film to move in close contact with the surface of the workbench, so that the composite film can pass through the detecting mechanism smoothly, thereby reducing the risk that the bending and folding of the composite film affect the detection result, and further reducing the risk of deviation of the composite film.

[0014] Optionally, the limiting assembly further comprises a guide gear and a control lever, the guide gear is rotationally connected with the workbench and is in mesh with the first rack, the control lever is fixedly connected with the guide gear towards the side of the support, the workbench is rotationally connected with a blocking piece and a spring, one end of the blocking piece is rotationally connected with the workbench, the other end is a free end, one end of the spring is fixedly connected with the workbench, the other end is fixedly connected with the blocking piece, and the spring is used to force the blocking piece to abut against the guide gear.

[0016] Optionally, the detection mechanism comprises a camera and a control console, the camera is electrically connected with the control console, the camera is fixed on the support and faces the workbench, and is used to detect the passing composite film.

[0017] By adopting the above technical scheme, when the composite film to be detected is located on the workbench at the bottom of the camera, the camera takes a photo of the part of the composite film, and compares it with the sample to detect whether the part of the composite film is a defective product.

[0018] Optionally, the transfer mechanism comprises a first transfer roller, a second transfer roller and an adjusting assembly, the adjusting assembly is slidably connected between the support and the vertical direction. The first transfer roller is rotationally connected with the support, the second transfer roller is rotationally connected with the adjusting assembly, a gap is left between the first transfer roller and the second transfer roller for the composite film to pass through, the first transfer roller is connected with a first motor, and the first motor drives the first transfer roller to rotate to drive the first transfer roller to rotate.

[0019] By adopting the above technical scheme, the operator adjusts the distance between the second transfer roller and the first transfer roller through the adjusting assembly to adapt to composite films of different thicknesses, so that the first transfer roller and the second transfer roller can have a clamping effect on composite films of different thicknesses, and the first motor can drive the first transfer roller to rotate to advance the composite film.

[0021] By adopting the above technical solution, the infrared sensor can identify the printed products on the composite film. For example, the camera's recognition range is two printed products. After the infrared sensor detects the two printed products passing by, it transmits an electrical signal to the control console. The control console controls the first motor to stop rotating, and the two printed products fall completely into the camera's recognition area, enabling the camera to take clear photos for comparison with the samples, thereby improving the accuracy of the detection. After the photo is taken, the control console controls the first motor to rotate, causing the first motor to produce intermittent motion to cooperate with the camera's photo detection.

[0022] Optionally, the marking mechanism includes a first cylinder and a marking assembly. The first cylinder is mounted on a bracket and electrically connected to a control console. The piston rod of the first cylinder is connected to the marking assembly. The piston rod of the first cylinder extends and retracts toward the worktable to mark defective composite films.

[0023] By adopting the above technical solution, when the camera detects a defective product, the first motor transports the defective product to the worktable at the bottom of the marking mechanism after multiple intermittent motion cycles. The control console controls the piston rod of the first cylinder to extend, so that the marking component contacts the defective product area and marks the defective product area, making it easier to find and remove the defective product later.

[0040] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0041] This application discloses a finished product testing and marking device.

[0042] The composite film 100 to be tested includes a printed film 101 and a surface cover film 102. The printed film 101 to be tested has block-shaped printed products. There is a long white border between adjacent block-shaped printed products. The white border is printed with long positioning color blocks, and there is a white gap between the positioning color blocks and the two adjacent printed products.

[0043] Reference Figure 1The finished product inspection and marking equipment includes a feeding mechanism 1, an inspection mechanism 2, a marking mechanism 3, and a winding mechanism 8. The feeding mechanism 1 transports the composite film 100 to one end of the inspection mechanism 2. The winding mechanism 8 carries the composite film 100 from the feeding mechanism 1 through the inspection mechanism 2 and the marking mechanism 3 in sequence. When the composite film 100 enters the identification area of ​​the inspection mechanism 2, the inspection mechanism 2 inspects the composite film 100. When the inspection mechanism 2 detects that the printed product is defective and the defective product moves to the bottom of the marking mechanism 3, the marking mechanism 3 marks the defective product, completing the inspection and marking operation of the composite film 100.

[0044] The bottom of the testing mechanism 2 is provided with a workbench 4 for load-bearing. The top of the workbench 4 is a plane for the composite film 100 to move. A bracket 41 is fixedly connected to the top of the workbench 4. The feeding mechanism 1, the testing mechanism 2 and the marking mechanism 3 are all fixed on the bracket 41 in sequence. The winding mechanism 8 is located at the end of the workbench 4 away from the feeding structure.

[0045] refer to Figure 2 A pressing mechanism 5 is provided between the feeding mechanism 1 and the detection mechanism 2. The feeding mechanism 1 includes a feeding roll 13, a first slitting roller group 11, and a second slitting roller group 12. The feeding roll 13 winds up the composite film 100 to be detected. The feeding roll 13 is rotatably connected to the support 41. Both the first slitting roller group 11 and the second slitting roller group 12 are rotatably connected to the support 41. The second slitting roller group 12 is located below the first slitting roller group 11. After the composite film 100 leaves the feeding roll 13 and enters the first slitting roller group 11, it is separated into a printing film 101 and a surface cover film 102. The printing film 101 is wound around the first slitting roller group 11, while the surface cover film 102 is wound around the second slitting roller group 12.

[0046] The first slitting roller group 11 includes a first pre-tensioning roller 111, a second pre-tensioning roller 112, and a first rotary roller 113, which are rotatably connected to the support 41 in sequence. The second slitting roller group 12 includes a second rotary roller 121, a third pre-tensioning roller 122, a fourth pre-tensioning roller 123, and a dust removal roller 124, which are rotatably connected to the support 41 in sequence.

[0047] The composite film 100 winds from the top of the first pre-tightening roller 111 to the bottom of the second pre-tightening roller 112. Upon leaving the second pre-tightening roller 112, the composite film 100 separates into a printing film 101 and a surface cover film 102. The printing film 101 winds towards the top of the first rotary roller 113. The separated surface cover film 102 winds towards the top of the third pre-tightening roller 122. After passing the bottom of the second rotary roller 121 and the top of the fourth pre-tightening roller 123, the surface cover film 102 winds around the bottom of the dust removal roller 124 and enters the extrusion mechanism 5 to remove dust from the surface cover film 102 and improve the accuracy of the inspection. The surface cover film 102 and the printing film 101 enter the extrusion mechanism 5 together. It is worth noting that after the composite film 100 separates, the printing film 101 and the surface cover film 102 travel the same distance, allowing them to enter the extrusion mechanism 5 simultaneously at the separation point.

[0048] refer to Figure 3 The extrusion mechanism 5 includes a first pressing roller 51, a second pressing roller 52, and an adjusting assembly 73. A bracket 41 is fixedly connected to the top of the worktable 4. The first pressing roller 51 is rotatably connected to the bracket 41. The adjusting assembly 73 includes a screw 731 and a limiting member 732. The limiting member 732 is fixedly connected to one end of the screw 731. The screw 731 is vertically connected to the bracket 41 by a thread. The end of the screw 731 facing away from the limiting member 732 is threadedly connected to a limiting turntable 733 and a pre-tightening turntable 734. The second pressing roller 52 is rotatably connected to the inner wall of the limiting member 732, and the outer wall of the limiting member 732 is slidably connected to the bracket 41.

[0049] The rotation axis of the first pressing roller 51 and the rotation axis of the second pressing roller 52 are located in the same vertical plane. A gap is left between the first pressing roller 51 and the second pressing roller 52 for the printing film 101 and the surface covering film 102 to pass through. Each end of the second pressing roller 52 is connected to an adjustment component 73. The operator can control the second pre-tightening roller 112 to rise or fall vertically by rotating the limit turntable 733, so that the second pre-tightening roller 112 moves closer to or away from the first pre-tightening roller 111. By adjusting the gap between the first pressing roller 51 and the second pressing roller 52, pressure is applied to the printing film 101 and the surface covering film 102 to bond them together and form the composite film 100 again.

[0050] refer to Figure 4 and Figure 5The adjustment mechanism 6 includes a limiting component 61 and a guiding component 62. The limiting component 61 includes a drive gear 611, a first rack 612, and a second rack 613. The surface of the worktable 4 is provided with a slide groove 42, located between the pressing mechanism and the light inlet groove 43. The drive gear 611 is rotatably connected to the slide groove 42, and its rotation axis is vertically oriented. The drive gear 611 meshes with the first rack 612 and the second rack 613, which are parallel to each other and slidably connected within the slide groove 42. A guiding component 62 is connected to the side of the first rack 612 and the second rack 613 facing away from the worktable 4. It is worth noting that the first rack 612, the second rack 613, and the drive gear 611 are all located within the slide groove 42 to reduce resistance to the composite membrane 100 passing over the slide groove 42.

[0051] A guide gear 614 and a control lever 615 are provided on the side of the first rack 612 away from the drive gear 611. The guide gear 614 is rotatably connected to the surface of the worktable 4 and meshes with the first rack 612. The control lever 615 is fixedly connected to the guide gear 614. The operator can control the movement of the first rack 612 by rotating the control lever 615. The inner wall of the slide 42 is provided with a blocking member 616 and a spring 617. One end of the blocking member 616 is rotatably connected to the inner wall of the slide 42, and the other end of the blocking member 616 is a free end. One end of the spring 617 is fixedly connected to the inner wall of the slide 42, and the other end of the spring 617 is fixedly connected to the blocking member 616. The spring 617 forces the free end of the blocking member 616 to abut against the guide gear 614 circumferentially, thereby restricting the rotation of the guide gear 614.

[0052] The guide assembly 62 includes an elastic restraint 621 and a roller 622. Taking the first rack 612 as an example, the roller 622 is rotatably connected to the side of the first rack 612 away from the worktable 4. The rotation axis of the roller 622 is vertically arranged, and part of the roller 622 protrudes from the slide groove 42. One end of the elastic restraint 621 is fixedly connected to the rotation axis of the roller 622, and the other end abuts against the surface of the worktable 4. The abutting end of the elastic restraint 621 against the worktable 4 is an arc surface to reduce wear on the elastic restraint 621.

[0053] The operator removes the obstruction 616 and then rotates the control lever 615 to control the guide gear 614 to rotate, forcing the first rack 612 to drive a set of guide components 62 to slide towards the drive gear 611. The first rack 612 drives the drive gear 611 to rotate, thereby forcing the second rack 613 to drive another set of guide components 62 to slide towards the drive gear 611. This results in the two sets of guide components 62 moving closer to each other in opposite directions, causing the two rollers 622 to limit the composite film 100 on the worktable 4. The two elastic limiting members 621 cooperate with the surface of the work strip to clamp the composite film 100, thereby accurately positioning and guiding the composite film 100 and improving the accuracy of subsequent testing of the composite film 100.

[0054] The workbench 4 is equipped with a transfer mechanism 7, which includes a first transfer roller 71, a second transfer roller 72, and a first motor 75. Both ends of the first transfer roller 71 are rotatably connected to the support 41. The first motor 75 is located at one end of the first transfer roller 71, and its housing is fixedly connected to the side wall of the workbench 4. The output shaft of the first motor 75 is fixedly connected to the third roller via a coupling. Each end of the second transfer roller 72 is connected to an adjusting assembly 73. A limiting member 732 is fixedly connected to one end of a screw 731, which is vertically connected to the support 41. The end of the screw 731 facing away from the limiting member 732 is threadedly connected to a limiting turntable 733 and a pre-tightening turntable 734. The second pressing roller 52 is rotatably connected to the inner wall of the limiting member 732, and the outer wall of the limiting member 732 is slidably connected to the support 41. The adjustment component 73 can adjust the first transfer roller 71 and the second transfer roller 72 to clamp composite films 100 of different thicknesses and drive the composite films 100 to move.

[0055] refer to Figure 6 and Figure 7 An infrared sensor 74 is fixedly connected to the bracket 41. The infrared sensor 74 is positioned towards the composite film 100 and is used to detect the composite film 100 passing through the rotating mechanism. Both the infrared sensor 74 and the first motor 75 are electrically connected to the control console 23. After the infrared sensor 74 identifies the positioning color block, it sends an electrical signal to the control console 23, causing the control console 23 to stop the first motor 75 for detection by the camera component 21. After detection, the control console 23 automatically controls the first motor 75 to rotate, allowing the composite film 100 to continue moving forward.

[0056] refer to Figure 8The testing mechanism 2 includes a camera assembly 21 and a display assembly 22. The camera assembly 21 includes a camera 211 and a light strip 212. The workbench 4 has a light inlet groove 43 located on the moving path of the composite film 100. The light strip 212 is fixedly installed in the light inlet groove 43. The camera 211 is fixedly connected to the bracket 41 and is set facing the light inlet groove 43 for visual recognition and testing of the composite film passing through the light inlet groove 43.

[0057] The display component 22 includes a first display screen 221 and a second display screen 222. A control console 23 is provided on one side of the workbench 4. The first display screen 221, the second display screen 222, and the camera 211 are all electrically connected to the control console 23.

[0058] Infrared camera 211 identifies and positions color blocks. Every time infrared camera 211 identifies two color blocks, the first motor 75 stops, causing intermittent movement of the composite film 100. When the first motor 75 stops, there are two complete printed products in the identification area directly in front of camera 211. Camera 211 detects the two printed products passing under its bottom. After a two-second delay, the first motor 75 resumes rotating the composite film 100.

[0059] The first display screen 221 establishes a comparison sample for testing by scanning. During testing, the printed product identified by the camera 211 is compared with the test sample for identification. When the camera 211 detects a defective printed product during scanning, it is displayed on the second display screen 222 for real-time monitoring by the operator.

[0060] refer to Figure 9 The marking mechanism 3 includes a first cylinder 31 and a marking assembly 32. The cylinder body of the first cylinder 31 is fixedly connected to the bracket 41. The marking assembly 32 includes a mounting clip 321, a limiting ring 322, and a marker pen 323. The limiting ring 322 and the mounting clip 321 are both fixed to the end of the piston rod of the first cylinder 31. The marker pen 323 passes through the limiting ring 322 and the mounting clip 321 in sequence. The mounting clip 321 is connected to a bolt and a nut for adjusting the tightness of the marker pen 323. Tightening the bolt and nut allows the mounting clip 321 to fit the marker pen 323, thereby reducing the risk of the marker pen 323 slipping off.

[0061] The winding mechanism 8 includes a tripod 81, a second motor 82, and a winding roller 83. The housing of the second motor 82 is rotatably and fixedly connected to the tripod 81, and the winding roller 83 is rotatably connected to the tripod 81. The output shaft of the second motor 82 is fixedly connected to the winding roller 83 through a coupling. The composite film 100 is wound onto the surface of the winding roller 83. The second motor 82 drives the winding roller 83 to rotate at a uniform speed, so that the composite film 100 moves forward at a uniform speed with the rotation of the winding roller 83.

[0062] A buffer platform 44 is provided between the winding mechanism 8 and the marking mechanism 3, allowing the composite film 100 to pass sequentially through the buffer platform 44 on the workbench 4. The height of the buffer platform 44 is lower than that of the workbench 4 and the winding mechanism 8. When the composite film 100, having completed the inspection and marking processes, enters the buffer platform 44, the composite film 100 is in a relaxed state. Under its own gravity, the composite film 100 bends downward in a U-shape, providing a movement margin for the intermittent movement of the transfer mechanism 7 and the uniform movement of the winding mechanism 8, thus avoiding the risk of the composite film 100 being pulled apart or broken.

[0063] The implementation principle of Example 1 is as follows: The composite film 100 to be tested enters the first slitting roller group 11 from the feeding roll 13. After passing around the second pre-tightening roller 112, the composite film 100 is separated into a printing film 101 and a surface cover film 102. The printing film 101 passes around the top of the first rotary roller 113, and the surface cover film 102 passes around the bottom of the second rotary roller 121. After the same stroke, the printing film 101 and the surface cover film 102 simultaneously enter the extrusion mechanism 5. The printing film 101 and the surface cover film 102 simultaneously pass through the gap between the first pressing roller 51 and the second pressing roller 52, and are extruded and bonded again to become the composite film 100, thereby removing air bubbles from the printing film 101 and the surface cover film 102. As the composite film 100 passes over the surface of the workbench 4, the operator removes the obstruction 616 and rotates the control lever 615 to control the guide gear 614 to rotate, forcing the drive gear 611 to rotate. The first rack 612 and the second rack 613 move closer or further apart, allowing the two rollers 622 to abut against the sides of the composite film 100, guiding the composite film 100 precisely toward the bottom of the camera 211. At this time, the elastic limiting member 621 and the surface of the workbench 4 clamp the composite film 100, ensuring the flatness of the composite film 100 and improving the detection accuracy of the camera 211. The first transfer roller 71 and the second transfer roller 72 clamp the composite film 100, and the first motor 75 drives the first transfer roller 71 to rotate, thereby moving the composite film 100 toward the marking mechanism 3. After the infrared sensor 74 identifies two positioning color blocks, it transmits an electrical signal to the control console 23. The control console 23 controls the first motor 75 to stop rotating, causing the composite film 100 to stop moving forward. The camera 211 captures the printed product of the printed film 101 located at the bottom of the camera 211 and compares it with the sample to detect whether it is a defective product. When the detection result is a defective product, the area moves intermittently to the calibration mechanism as the transfer mechanism 7 moves. The piston rod of the first cylinder 31 drives the marker pen 323 to mark the defective area, which is convenient for subsequent cutting and separation. After marking, the composite film 100 is conveyed to the buffer table 44. At this time, the composite film 100 is in a relaxed state. The winding roller 83 winds up the composite film 100 for the next process.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
