Description

Technical Field

[0001] This utility model belongs to the field of packaging equipment technology, and in particular relates to a packaging machine for slider components. Background Technology

[0002] After production, slider components need to be packaged and stored to protect them and improve storage efficiency. Existing slider component packaging machines typically consist of a conveying device and a packaging sealing device. The packaging sealing device seals the packaging bag containing the slider components through heat sealing. For example, a pillow-type packaging machine empty package rejection device disclosed in patent application number CN202322747062.6 includes a machine body, a fixed frame, a support frame, a lifting assembly located on the top of the machine body and the back of the fixed frame, as well as contact blocks, connecting springs, and sensors.

[0003] In this type of existing packaging machine, the adhesive film at the bag opening is prone to melting and overflowing during heat sealing, which contaminates the sealing device and affects subsequent sealing processes, thus reducing the packaging effect of the machine. Therefore, it is necessary to make improvements. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a slider component packaging machine, thereby effectively improving the packaging effect of the slider component packaging machine.

[0005] In view of this, the present invention provides a slider component packaging machine, comprising:

[0006] A conveying device, the conveying device comprising a conveyor belt with workpiece grooves arranged on its surface;

[0007] A sealing device, which is disposed above the conveying device for sealing a packaging bag containing a slider component;

[0008] The sealing device further includes:

[0009] A heating block having a heating surface;

[0010] A pressure block, used to press the opening of the packaging bag against the heating surface of the heating block;

[0011] The lower part of the heating surface bears a greater pressure than the upper part.

[0012] In this technical solution, during the packaging process, the packaging bag is placed in the workpiece groove of the conveyor belt, and the slider component is placed inside the packaging bag. As the conveyor belt rotates, the packaging bag is moved to the sealing device. The opening of the packaging bag is placed between the heating block and the pressure block. Then, the pressure block presses the opening of the packaging bag against the heating surface of the heating block. The heating surface of the heating block heat-seals the opening of the bag. During the heat-sealing process, the lower part of the heating surface bears greater pressure than the upper part, thereby ensuring that the bottom of the bag opening is fully melted and sealed, while the top of the bag opening is under lower pressure, resulting in a lower melting temperature. This effectively prevents the adhesive film from melting and overflowing. Compared with the prior art, this utility model can effectively improve the packaging effect of the slider component packaging machine.

[0013] Furthermore, the above technical solution also includes:

[0014] The LED lighting unit is disposed on one side of the conveying device and located on the outlet side of the sealing device;

[0015] A camera is positioned above the LED lighting unit with its visual receiving end facing the workpiece groove.

[0016] The LED lighting unit illuminates the sealed packaging bag at a specific angle so that any imperfections at the sealed opening appear as a white sheen in the camera image.

[0017] In the above technical solution, the LED lighting unit is located on one side of the conveyor belt and emits light upwards towards the packaging bag at a position lower than the packaging bag.

[0018] In the above technical solution, the distance between the camera and the packaging bag is further 12-50mm.

[0019] In the above technical solution, the heating surface is further described as a stepped heating surface, which consists of a main heating surface and a secondary heating surface. The main heating surface is located below the secondary heating surface, and the protrusion distance of the main heating surface is greater than that of the secondary heating surface.

[0020] In the above technical solution, the heating block is further described as a split heating block, which includes an upper heating block and a lower heating block that can be moved independently.

[0021] The beneficial effects of this utility model are:

[0022] 1. By designing the lower part of the heating surface to have a higher pressure than the upper part, combined with the temperature control of the stepped heating surface or the split heating block, the melting and overflow of the adhesive film at the top of the bag opening is effectively reduced, the degree of contamination of the sealing device is reduced, the stability and reliability of subsequent sealing processes are ensured, and the packaging effect of the packaging machine is improved.

[0023] 2. The greater pressure and suitable temperature at the bottom make the bottom of the bag mouth more firmly bonded, resulting in better sealing and reducing problems such as moisture and oxidation of the slider parts caused by poor sealing, thus improving the storage effect of the product;

[0024] 3. The defect detection system, consisting of LED lighting and a camera, can detect defects at the bag opening seal in real time and accurately, preventing defective products from entering the next process and improving the product pass rate. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0035] Example 1:

[0036] This application provides a slider component packaging machine, including: a conveying device, the conveying device including a conveyor belt 1 with workpiece grooves 100 arranged on its surface; and a sealing device 2, the sealing device 2 being disposed above the conveying device for sealing a packaging bag 13 containing slider components.

[0037] The sealing device 2 also includes: a heating block 3 having a heating surface; and a pressure block 4 for pressing the opening of the packaging bag 13 against the heating surface of the heating block 3.

[0038] The lower part of the heating surface bears greater pressure than the upper part.

[0039] The heating surface is a stepped heating surface, which consists of a main heating surface 5 and a secondary heating surface 6. The main heating surface 5 is located below the secondary heating surface 6, and the protrusion distance of the main heating surface 5 is greater than that of the secondary heating surface 6.

[0040] Moreover, the conveying device has a conventional structure. Specifically, the main body of the conveying device is welded from aluminum alloy profiles. The conveyor belt 1 is installed on the upper part of the frame to support the guide rail. The guide rail is a linear guide rail. The conveyor belt 1 can be a polyurethane synchronous belt. The conveyor belt 1 is tensioned by a drive roller and a driven roller. The drive roller is connected to the output shaft of the servo motor through a flat key. The two ends of the driven roller are installed on an adjustable tension bracket. The tension bracket is connected to the frame guide rail through a slider and can move laterally along the guide rail. The workpiece groove 100 is evenly distributed along the length of the conveyor belt 1. The heating block 3 is equipped with a heating element, such as a resistance wire, and the heating temperature can be controlled by a temperature controller. The protrusion distance of the main heating surface 5 is 3mm, and the protrusion distance of the secondary heating surface 6 is 1mm. The pressure block 4 is driven by a conventional cylinder or hydraulic cylinder. Similarly, the heating block 3 can also be driven and adjusted by connecting to the corresponding cylinder or hydraulic cylinder, which is convenient for the staff to adjust the heat sealing position.

[0041] In this technical solution, during the packaging process, the packaging bag 13 is placed in the workpiece groove 100 of the conveyor belt 1, and the slider component is placed inside the packaging bag 13. As the conveyor belt 1 rotates, the packaging bag 13 is moved to the sealing device 2. The opening of the packaging bag 13 is placed between the heating block 3 and the pressure block 4. Then, the pressure block 4 presses the opening of the packaging bag 13 against the heating surface of the heating block 3. The heating surface of the heating block 3 heat-seals the opening of the bag. During the heat-sealing process, the lower part of the heating surface bears greater pressure than the upper part, thereby ensuring that the bottom of the bag opening is fully melted and sealed, while the top of the bag opening is under lower pressure and the melting temperature decreases, effectively preventing the adhesive film from melting and overflowing. Compared with the prior art, this utility model can effectively improve the packaging effect of the slider component packaging machine.

[0042] Example 2:

[0043] This embodiment provides a slider component packaging machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including: an LED lighting unit 7, which is disposed on one side of the conveying device and located on the outlet side of the sealing device 2; and a camera 8, which is disposed above the LED lighting unit 7 and whose visual receiving end faces the workpiece groove 100.

[0044] The LED lighting unit 7 illuminates the sealed packaging bag 13 at a specific angle so that the imperfections at the sealed opening of the bag appear as a white luster in the image captured by the camera 8.

[0045] The LED lighting unit 7 is located on one side of the conveyor belt 1 and is tilted upwards at a position lower than the packaging bag 13, emitting light toward the packaging bag 13.

[0046] The distance between the camera 8 and the packaging bag 13 is 12-50mm.

[0047] Furthermore, it also includes a conventional control and processing unit 9, such as an industrial computer. The LED lighting unit 7 consists of a lamp board and a bracket. The lamp board is made of an aluminum substrate and high-brightness white LEDs are mounted on the surface. They are arranged in a matrix and the light emission angle is optimized to 30° by optical design to ensure that the light shines on the bag opening seal at a specific angle. Preferably, the LED lighting unit 7 is installed on the side of the conveyor belt 1, 20mm below the bottom of the packaging bag 13, and emits light towards the bag opening seal at a 35° upward angle, so that the seal wrinkles produce a mirror reflection to form a white luster.

[0048] Camera 8 is an industrial-grade monochrome camera with a fixed-focus lens. The focal length is set to 8-12mm. Camera 8 is fixed directly above the LED lighting unit 7 using a conventional three-dimensional adjustment bracket. The vertical distance between camera 8 and the packaging bag 13 is strictly controlled within the range of 12-50mm. This distance is automatically adjusted by an electric push rod with an adjustment accuracy of ±0.5mm. The optical axis of camera 8 forms a 45° angle with the LED lighting light to avoid interference from direct light. Camera 8 captures the sealing image in high-speed continuous shooting mode (frame rate ≥30fps). At least 3 frames are acquired for each inspection for data fusion. Optional black-and-white inversion processing technology is used to convert white glossy areas in the image into black areas for subsequent counting processing. The inversion threshold can be adjusted by software. Using a gloss counting algorithm, connected component analysis is performed on the preprocessed image to extract the quantity, area, shape, and other feature parameters of white gloss (or inverted black areas). The extracted feature parameters are compared with a preset threshold. If the number of glosses exceeds the preset threshold (e.g., 5 glosses / 100mm²), it is judged as a defective product.

[0049] Camera 8 is connected to the industrial computer in the control cabinet via a GigE interface, with a data transmission rate of ≥1Gbps; LED lighting unit 7 is powered by a 24V DC power supply, and the power module communicates with the computer via an RS485 bus; the camera 8 detection system and the conveying device are synchronized via encoder signals; when the packaging bag 13 reaches the detection position, the encoder sends a trigger signal to the computer to start the camera 8 exposure, ensuring accurate image acquisition position.

[0050] Preferably, a conventional gripping robot 10 is also installed on one side of the conveyor belt 1 for handling defective packaging bags 13.

[0051] In this embodiment, the sealed packaging bag 13 continues to move along the conveyor belt 1 to the detection area of ​​the LED lighting unit and the camera 8. The LED lighting unit is located on one side of the conveyor belt 1 and emits light upwards at a position lower than the packaging bag 13, illuminating the sealed area of ​​the bag opening at a specific angle. When there are defects at the sealed area of ​​the bag opening, such as poor shrinkage, weak adhesion, or air bubbles, these defects will change the reflection path of the light, causing the defective area to appear white and shiny in the image captured by the camera 8, while the normally sealed area appears darker. The camera 8 can clearly capture the image of the sealed area of ​​the bag opening. The camera 8 transmits the acquired image to the control processing unit 9, which analyzes the image using an image recognition algorithm to identify the white and shiny areas, thereby determining whether there are defects at the sealed area of ​​the bag opening. If a defect is detected, the system can issue an alarm or control a corresponding rejection device, such as a gripping robot 10, to reject the defective packaging bag 13, ensuring the packaging quality of the product.

[0052] Example 3:

[0053] This embodiment provides a slider component packaging machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the heating block 3 is a split heating block 3, which includes an upper heating block 11 and a lower heating block 12 that can be moved independently.

[0054] Furthermore, a vision sensor 14 for visual inspection is arranged above the split heating block 3, and the split heating block 3 is also controlled by a conventional cylinder or hydraulic cylinder.

[0055] In this embodiment, when the adhesive film tends to overflow during the heat sealing process of the packaging tape, the vision sensor 14 detects the risk of overflow and triggers a cylinder or hydraulic cylinder through a control device such as an industrial computer to move the upper heating block 11 backward, thereby reducing the contact between the heating surface of the upper heating block 11 and the bag opening, thus reducing the melting temperature and reducing the overflow of the adhesive film.

[0056] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
