A kind of automatic edge sealing machine rack structure

Abstract

This utility model relates to the field of edge banding machine frame technology, specifically an automatic edge banding machine frame structure. Due to differences in the surface condition of the edge banding strip, the angle and intensity of reflected laser light will vary. If the edge banding strip surface is flat, the reflected laser light is relatively regular; if the edge banding strip surface has wrinkles, it will change the reflection path and intensity of the laser, and the laser signal received by the laser receiving device will be different from the signal on a normal flat surface. By analyzing the signal received by the laser receiving device, it is possible to determine whether the edge banding is qualified. The inspection station transmits the inspection result to the sorting station. The sorting station completes the product sorting based on the result. This allows edge banding, inspection, and product sorting to be completed on a continuous production line, optimizing the entire edge banding production process. It avoids production interruptions and chaos caused by manual handling and secondary inspections, improving the smoothness and continuity of production. It can be widely applied in the field of edge banding machine frame technology.

Description

Technical Field

[0001] This utility model relates to the field of edge banding machine frame technology, and more specifically, to an automatic edge banding machine frame structure. Background Technology

[0002] Automatic edge banding machines are used to band the edges of various types of boards. Their working principle is as follows: The boards first enter the automatic edge banding machine via a conveyor structure. The conveyor structure accurately transports the boards to each processing station at a stable speed. When the boards reach the glue application station, glue is evenly applied to the areas of the board to be banded using glue rollers.

[0003] Subsequently, the edge banding feeding device retrieves the edge banding strip from its storage location and conveys it to the edge of the glued board according to the set length and speed. Next, the bonding device applies a certain pressure to ensure that the edge banding strip is tightly bonded to the board. After the adhesive cures, a strong bond is achieved between the two.

[0004] However, in actual production, edge banding defects may occur after the sealing process. For example, the edge banding strip may have wrinkles on its surface. Currently, these defective products typically require manual secondary inspection and processing. This not only increases labor costs and reduces production efficiency, but manual inspection is also inevitably subject to subjective errors and missed detections. Furthermore, because the frame structure of automatic edge banding machines may not have been adequately designed to integrate edge banding quality inspection and defective product handling processes, the connection between edge banding, inspection, and defective product handling in the entire production process is not smooth enough.

[0005] Therefore, developing an automatic edge banding machine frame structure that can better optimize the edge banding process, effectively detect edge banding quality, and reasonably handle defective products is of great practical significance and will help improve the production quality and efficiency of furniture manufacturing and other related industries. Utility Model Content

[0006] In view of the problems existing in the prior art, this utility model proposes an automatic edge banding machine frame structure.

[0007] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0008] An automatic edge banding machine frame structure includes a conveyor belt and support plates located on both sides of the conveyor belt. An edge banding station, an inspection station, and a diversion station are sequentially arranged between the two support plates along the conveyor belt travel direction. A laser generating device is provided on the side wall of one support plate at the inspection station, and a laser receiving device is provided on the side wall of the other support plate at the inspection station. The laser emitted by the laser generating device enters the laser receiving device after being reflected by the material on the conveyor belt.

[0009] The conveyor belt transports the boards to the edge banding station, the inspection station, and the sorting station in sequence at a stable speed.

[0010] At the edge banding station, according to the conventional working principle of the automatic edge banding machine, the glue applicator roller first evenly applies glue to the edge to be banded on the board. Subsequently, the edge banding strip feeding device sends the edge banding strip to the edge of the glued board, and the fitting device applies pressure to make the edge banding strip closely fit the board. Wait for the adhesive to cure to complete the edge banding. When the edge-banded board reaches the inspection station, the laser generating device on the side wall of the supporting plate on one side emits laser light. The laser light irradiates the surface of the edge-banded board on the conveyor belt and is reflected. The reflected laser light enters the laser receiving device on the side wall of the supporting plate on the other side. Due to the different surface conditions of the edge banding strip, the characteristics of the reflected laser light, such as the angle and intensity, will vary. If the surface of the edge banding strip is flat, the reflected laser light is relatively regular; if there are wrinkles on the surface of the edge banding strip, it will change the reflection path and intensity of the laser light, and the laser signal received by the laser receiving device will be different from the signal of the normal flat surface. By analyzing the signal received by the laser receiving device, it is possible to judge whether the edge banding is qualified, such as whether there are problems such as wrinkles. The inspection station transmits the inspection result of whether the edge banding is qualified to the sorting station. The sorting station completes the sorting of the products according to this result.

[0011] The rack structure is provided with an edge banding station, an inspection station, and a sorting station in sequence along the direction of the conveyor belt travel, so that edge banding, inspection, and product sorting are completed on a coherent production line, closely connecting each link, and optimizing the entire edge banding production process. It avoids the interruption and chaos of the production process caused by manual handling, secondary inspection, etc., and improves the fluency and coherence of production.

[0012] As a preference; a dust-proof board is provided above the conveyor belt between the edge banding station and the inspection station, and a brush is installed on the lower end surface of the dust-proof board.

[0013] The brush installed on the lower end surface of the dust-proof board will contact the surface of the board. As the board moves on the conveyor belt, the brush sweeps the edge banding surface of the board. Its purpose is to clean impurities such as glue stains and debris that may be generated during the edge banding process, and prevent these impurities from affecting the accuracy of the laser detection in the subsequent inspection station. Because impurities may change the reflection characteristics of the laser light, resulting in deviation of the detection result. Through the setting of the dust-proof board and the brush, it is ensured that the edge banding surface of the board reaching the inspection station is relatively clean, providing good conditions for accurate detection.

[0014] As a preference; a light-proof board is provided between the inspection station and the sorting station. A top board is provided on the upper end surfaces of the light-proof board and the dust-proof board. The dust-proof board, the light-proof board, and the top board are all made of opaque materials.

[0015] The dustproof panel, light-blocking panel, and top panel are all made of opaque material, creating a relatively enclosed space. When the laser emitted by the laser generator shines on the edge of the panel and is reflected to the laser receiver for detection, the light-blocking panel effectively blocks external light from entering the detection area, preventing external light from interfering with the laser detection.

[0016] Preferably, the lower end face of the dustproof plate is provided with a mounting groove, the brush includes a base plate and bristles set on the base plate, the upper end face of the brush is fixed with a mounting part that can extend into the mounting groove, the side wall of the mounting groove is provided with a mounting hole, and the side wall of the mounting part is provided with a connecting hole; it also includes bolts, when the mounting part extends into the mounting groove, the mounting hole and the connecting hole are coaxial, and the bolts can pass through the mounting hole and the connecting hole in sequence to fix the mounting part in the mounting groove.

[0017] The mounting part is securely fixed in the mounting groove by utilizing the friction between the bolt threads and the hole wall, thus achieving stable installation of the brush on the lower end face of the dustproof plate. During the material conveying process, the bristles at the lower end of the fixed brush contact the edge sealing surface of the material to clean impurities. When the brush becomes worn or needs to be replaced after a period of use, simply unscrew the bolts to remove the mounting part of the brush from the mounting groove for easy replacement with a new brush.

[0018] As a preferred embodiment, one of the support plates has an electric push rod located at the diversion station on its side wall, and the other support plate has a waste outlet on its side wall. The electric push rod can push out unqualified products from the conveyor belt through the waste outlet.

[0019] The design of the push rod and waste inlet automates the diversion of defective products. This eliminates the need for manual removal of defective products from the conveyor belt, significantly improving diversion efficiency, reducing manual intervention, and further enhancing the automation of the entire edge-sealing production process. This not only speeds up production but also reduces potential errors caused by manual operation.

[0020] Preferably, a light polarizing glass plate is placed in front of the laser receiving device.

[0021] Optically polarizing glass only allows light with a specific polarization direction to pass through. When an optically polarizing glass is placed in front of a laser receiver, when laser light reflected from the surface of the edge-sealing material and stray light from the outside reaches the optically polarizing glass, only light with the polarization direction that matches the allowed polarization direction can pass through smoothly; light with other polarization directions is blocked or significantly attenuated. In this way, the light signal reaching the laser receiver is purer, mainly consisting of laser signals reflected from the surface of the edge-sealing material with the required polarization direction, reducing stray light interference.

Detailed Implementation

[0029] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0030] Example

[0031] like Figures 1-5 As shown, the frame structure of the automatic edge banding machine in this embodiment mainly consists of a conveyor belt 110 and support plates 120 located on both sides of the conveyor belt 110. Between the two support plates 120, along the traveling direction of the conveyor belt 110, edge banding station 1301, inspection station 1302 and diversion station 1303 are arranged in sequence.

[0032] At inspection station 1302, a laser generator 1401 is installed on the side wall of one support plate 120, and a laser receiver 1402 is installed at a corresponding position on the side wall of the other support plate 120. A polarizing glass plate is provided in front of the laser receiver 1402. Between the sealing station 1301 and the inspection station 1302, a dustproof plate 150 is provided above the conveyor belt 110. The lower end face of the dustproof plate 150 has a mounting groove 1501. The brush 180 consists of a base plate and bristles on the base plate. The mounting part 1803 fixed on its upper end face can extend into the mounting groove 1501. The side wall of the mounting groove 1501 and the side wall of the mounting part 1803 are respectively provided with coaxial mounting holes 1502 and connecting holes 1804. The brush 180 is fixed on the lower end face of the dustproof plate 150 by bolts 190 passing through them.

[0033] A light-blocking plate 160 is provided between the inspection station 1302 and the diversion station 1303. The upper surfaces of the light-blocking plate 160 and the dust-blocking plate 150 are connected to a top plate 170. The dust-blocking plate 150, the light-blocking plate 160 and the top plate 170 are all made of opaque material, forming a relatively enclosed space. At the diversion station 1303, an electric push rod 200 is provided on the side wall of one side support plate 120, and a waste outlet 1201 is provided on the side wall of the other side support plate 120.

[0034] Its specific operating principle is as follows:

[0035] The conveyor belt 110 transports the sheet material to the edge banding station 1301 at a stable speed. An automatic edge banding machine is installed at this station; the automatic edge banding machine performs the edge banding operation on the sheet material.

[0036] After edge banding, the sheet material enters the inspection station 1302 via conveyor belt 110. A laser generator 1401 emits a laser beam, which illuminates and reflects off the surface of the edge banding sheet. Before reaching the laser receiver 1402, the reflected light passes through a polarizing glass plate. Only light with the polarization direction permitted by the polarizing glass plate can pass through the laser beam reflected from the edge banding sheet surface, along with stray light. Light with other polarization directions is blocked or significantly attenuated, resulting in a purer light signal reaching the laser receiver 1402, consisting mainly of laser signals reflected from the edge banding sheet surface with the required polarization direction. Due to variations in the surface condition of the edge banding strip, the angle and intensity of the reflected laser differ. If the edge banding strip surface is flat, the reflected laser beam is relatively regular; however, wrinkles alter the reflection path and intensity of the laser, causing the signal received by the laser receiver 1402 to differ from that of a normally flat surface. By analyzing this signal, the quality of the edge banding can be determined, such as the presence of wrinkles or other issues. During this process, the brush 180 on the lower end face of the dustproof plate 150 cleans the sealing surface of the plate during conveying, removing adhesive residue, debris, and other impurities to prevent these impurities from altering the laser reflection characteristics and affecting the detection results. Simultaneously, the enclosed space formed by the dustproof plate 150, the light-blocking plate 160, and the top plate 170 effectively blocks external light from entering the detection area, preventing interference with laser detection. The laser incident angle emitted by the laser generator 1401 towards the plate is set between 30° and 60°.

[0037] Inspection station 1302 transmits the inspection results of whether the edge sealing is qualified to the sorting station 1303. When unqualified products are transported to the sorting station 1303, the electric push rod 200 is activated, pushing the unqualified products out of the waste port 1201 from the conveyor belt 110, while qualified products continue to be transported along the conveyor belt 110 to the subsequent process or storage area, thus completing the product sorting.

[0038] The above setup integrates edge banding, inspection, and product diversion on a single, continuous production line, seamlessly connecting each stage. This avoids production interruptions and chaos caused by manual handling and secondary inspections, significantly improving production flow and continuity, and increasing production efficiency.

[0039] The optically polarizing glass filter filters stray light, allowing the laser receiver 1402 to receive a purer signal and enhancing its anti-interference capability. The dustproof plate 150 and brush 180 clean impurities from the edge-sealing surface of the board, preventing impurities from interfering with laser detection. The enclosed space constructed by the light-blocking plate 160, dustproof plate 150, and top plate 170 blocks external light, preventing light interference with laser detection. These multiple measures work together to greatly improve the accuracy of edge-sealing quality inspection at the inspection station 1302, reducing misjudgments and omissions, and ensuring product quality.

[0040] The above design optimizes the use of production space, facilitates the centralized collection of defective products, and keeps the production site clean.

[0041] In summary, the above are merely preferred embodiments of this embodiment. All equivalent changes and modifications made in accordance with the scope of the patent application of this embodiment shall fall within the scope of the patent of this embodiment.
