Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, and more specifically, to an adsorption and waste removal feeding device. Furthermore, this utility model also relates to a laser die-cutting machine including the aforementioned adsorption and waste removal feeding device. Background Technology

[0002] Among existing laser die-cutting machines, the types used for material feeding include perforated thin steel strips and needle-embedded synchronous belts;

[0003] Among them, the perforated thin steel strip uses the air holes on its surface to adsorb the workpiece carried by the thin steel strip. After the workpiece is die-cut, the waste material is separated from the workpiece in time. A hollow conveying mechanism needs to be set up downstream to remove the waste material. However, the non-hollow part of the hollow conveying mechanism will hinder the waste material from falling, affecting the separation efficiency between the waste material and the workpiece. In addition, the air holes of the thin steel strip are usually small and are easily blocked by waste material or dust, which will reduce the adsorption force of the workpiece and affect the adsorption effect of the workpiece.

[0004] The needles embedded in the timing belt are thin and tall, and the timing belt at the base of the needles is a flexible structure. This means that the needles may fall over, making it impossible for the top of the needles to form a stable and flat support surface. As a result, the flatness of the workpiece substrate is insufficient after vacuum adsorption, which also leads to insufficient sealing between the workpiece and the negative pressure area, affecting the adsorption effect of the workpiece.

[0005] In summary, how to solve the problem of poor material feeding and adsorption effect in die-cutting machines is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0058] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0059] The core of this utility model is to provide an adsorption and waste removal feeding device, which uses parallel and spaced toothed chains as feeding components to carry and feed the workpiece, effectively ensuring the negative pressure adsorption effect of the workpiece during the feeding process.

[0060] Another core aspect of this utility model is to provide a laser die-cutting machine that includes the above-mentioned adsorption and waste removal feeding device, which has the same technical features and can achieve the same technical effects.

[0061] Please refer to Figures 1-8 An adsorption waste removal feeding device, comprising:

[0062] The waste adsorption and collection assembly 3 includes a negative pressure chamber 32 with a single-sided opening;

[0063] The feeding assembly 2 includes several parallel and spaced conveyor chains 21 and a drive mechanism for driving the conveyor chains 21 to feed. The load-bearing part of the conveyor chain 21 is located at the opening of the negative pressure chamber 32. The conveyor chain 21 is a toothed chain.

[0064] like Figure 1 and Figure 3 As shown, the adsorption waste removal feeding device includes a negative pressure chamber 32. The top opening of the negative pressure chamber 32 is a negative pressure adsorption area. Therefore, the bearing part of several parallel and spaced conveyor chains 21, which are the feeding components 2, is set at the opening of the negative pressure chamber 32. When the workpiece substrate is fed, the substrate is supported on the surface of the conveyor chain 21 and is adsorbed by the negative pressure at the opening of the negative pressure chamber 32, thereby adsorbing the substrate on the surface of the conveyor chain 21 and feeding synchronously with the conveyor chain 21.

[0065] Moreover, the conveyor chains 21 are arranged in parallel with intervals, and there are gaps between adjacent conveyor chains 21 to allow airflow to pass through. That is, the negative pressure of the negative pressure chamber 32 can adsorb the workpiece substrate through the gaps between the conveyor chains 21, and after the workpiece substrate is die-cut, the waste can enter the negative pressure chamber 32 in time through the gaps between the conveyor chains 21 with the negative pressure airflow, thus realizing the rapid removal of waste from the substrate.

[0066] The conveyor chain 21 adopts a toothed chain, and its toothed part is rigidly connected to the chain part. Therefore, during the feeding process of the conveyor chain 21, the toothed part will not tilt relative to the chain part. That is, the toothed parts of all the bearing parts of the conveyor chain 21 can form a stable and flat support surface, which provides good support for the workpiece substrate, thereby increasing the air seal between the substrate and the adsorption area of ​​the negative pressure chamber 32, and ensuring the adsorption effect of the substrate.

[0067] In practical applications, to maintain the load-bearing capacity of the conveyor chain 21, a conveyor track 22 for support and guidance is provided on the load-bearing part of the conveyor chain 21, such as... Figure 4 and Figure 5 As shown, the conveying track 22 is a long strip structure, with its length direction consistent with the feeding direction of the conveying chain 21. The pointed teeth of the toothed chain are set on both sides of the chain, while the conveying track 22 is set in the gap between the pointed teeth on both sides. Through the mutual limiting of the pointed teeth on both sides and the conveying track 22, the conveying chain 21 is laterally limited.

[0068] Meanwhile, the use of a toothed chain, with the contact and support position between the toothed chain and the substrate being the top of the toothed part, results in a smaller obstruction of the substrate by the toothed chain, allowing the substrate to obtain a larger adsorption area. This avoids difficulties in separating waste from the substrate due to obstruction by the conveyor chain 21, effectively ensuring the separation efficiency of waste from the substrate.

[0069] like Figure 3As shown, the conveyor chain 21 is a closed-loop structure and is arranged around the negative pressure chamber 32. Only the part of the conveyor chain 21 that bears the load is located at the opening of the negative pressure chamber 32. Therefore, the driving roller 23 and the driven roller are respectively set at both ends of the negative pressure chamber 32 to drive the conveyor chain 21, and the tension roller 24 is set at other positions of the conveyor chain 21 to tension the conveyor chain 21.

[0070] In some embodiments, an airtight component 6 is provided at the opening of the negative pressure chamber 32 to increase the airtightness between the bearing part of the feed component 2 and the opening of the negative pressure chamber 32.

[0071] The airtight assembly 6 includes an annular structure consisting of two sets of side sealing plates 62 and two sets of end sealing plates 61 connected at intervals. The side sealing plates 62 are arranged on both sides of the feed assembly 2, and the end sealing plates 61 have a comb-like structure. The conveyor chain 21 passes through the gap area of ​​the comb-like structure.

[0072] like Figure 1 , Figure 3 and Figure 6 As shown, the feeding component 2 is located at the opening of the negative pressure chamber 32. There is a serious gas leakage problem at the contact position between the edge of the feeding component 2 and the opening of the negative pressure chamber 32, which affects the negative pressure adsorption effect of the substrate. Therefore, an airtight component 6 is set at the opening of the negative pressure chamber 32 to increase the airtightness between the negative pressure chamber 32 and the edge of the feeding component 2, reduce gas leakage, and improve the adsorption capacity of the adsorption area of ​​the negative pressure chamber 32 on the substrate.

[0073] The airtight assembly 6 includes two side sealing plates 62 to block external airflow from entering the negative pressure chamber 32 through the sides of the feed assembly 2, and also includes two end sealing plates 61, such as... Figure 1 and Figure 4 As shown, the end sealing plate 61 has a comb-like structure, and the conveyor chain 21 passes through the gaps in the comb-like structure, increasing the airtightness at both ends of the interval area of ​​the conveyor chain 21.

[0074] like Figure 3 and Figure 6 As shown, the negative pressure chamber 32 includes a bottom sealing part 321 and a top sealing part 322, which together form the negative pressure chamber 32 and are separable. The opening of the negative pressure chamber 32 is located in the top sealing part 322, and the edge of the opening of the top sealing part 322 is sealed to the lower edge of the airtight component 6.

[0075] In some embodiments, the airtight component 6 and the negative pressure chamber 32 are designed as a single unit, which can also achieve the above-mentioned functions.

[0076] In some embodiments, the adsorption waste removal feeding device further includes a brushing mechanism assembly 5 for removing waste carried by the non-load-bearing part of the feeding component 2;

[0077] The brushing mechanism assembly 5 includes a brush roller 51 and a drive motor 52 that drives the brush roller 51 to rotate;

[0078] The brush roller 51 is used to rotate and brush away the waste material carried by the non-load-bearing part of the conveyor chain 21;

[0079] The feeding direction of the outer periphery of the brush roller 51 is opposite to the feeding direction of the conveyor chain 21.

[0080] During use, feed component 2 generates waste or dust on its surface, which can affect the adsorption effect on the substrate and cause contamination. Therefore, if... Figure 3 As shown, a brushing mechanism assembly 5 is provided at the downstream end of the bearing part of the feed assembly 2 to clean the non-bearing part of the feed assembly 2 and remove waste and dust from the surface.

[0081] The brushing mechanism assembly 5 includes a brush roller 51 made of soft or hard bristles. The brush roller 51 is driven to rotate by a drive motor 52. The brush roller 51 contacts and rubs against the conveyor chain 21 to remove waste and dust from the surface of the conveyor chain 21.

[0082] When setting the brush roller 51, the feeding direction of the brush roller 51 is opposite to the feeding direction of the conveyor chain 21, so that the contact part of the two can obtain a larger relative speed, thereby improving the brushing effect.

[0083] In some embodiments, the adsorption and waste collection assembly 3 further includes a negative pressure air collection port 324, and the relative working position of the brushing mechanism assembly 5 and the feeding component 2 is located at the air collection port 324, for adsorbing the waste material removed by the brushing mechanism assembly 5 through the negative pressure of the air collection port 324.

[0084] like Figure 3 As shown, the interface positions of the bottom sealing part 321 and the top sealing part 322 of the negative pressure chamber 32 are reserved with air collection ports 324, which can also generate negative pressure attraction. Therefore, the brushing mechanism assembly 5 is set at the air collection port 324, or the interaction position between the brush roller 51 and the conveyor chain 21 is set at the air collection port 324, so that the waste and dust generated by the brushing mechanism assembly 5 can be attracted by the negative pressure of the air collection port 324 and enter the negative pressure chamber 32 for collection.

[0085] In some embodiments, the adsorption waste removal feeding device further includes a post-waste removal assembly 7 and a post-waste collection assembly 4;

[0086] The rear waste removal assembly 7 is located downstream of the feed assembly 2's supporting section;

[0087] The rear waste collection assembly 4 is used to collect the waste removed by the rear waste removal assembly 7.

[0088] like Figure 1 and Figure 2As shown, a post-waste cleaning assembly 7 and a post-waste collection assembly 4 are set at the downstream end of the bearing part of the feed assembly 2 to perform secondary waste cleaning on the workpiece substrate, further improving the separation effect of waste from the workpiece substrate and avoiding some waste from not being separated from the substrate.

[0089] In some embodiments, the post-waste cleaning assembly 7 includes a post-feed assembly 71 and a waste cleaning fan 72;

[0090] The rear feed assembly 71 is located at the downstream end of the carrying part of the feed assembly 2 and is used to receive the workpiece conveyed by the carrying part of the feed assembly 2.

[0091] The waste removal fan 72 is located above the rear feed assembly 71 and is used to separate waste from workpieces by means of airflow.

[0092] like Figure 1 As shown, the post-feed assembly 7 includes a post-feed assembly 71 that drives the substrate feeding and a post-feed blower 72 that forces the waste and the substrate to separate. The post-feed blower 72 is fixedly installed. When the substrate is fed into the working area of ​​the post-feed assembly 71, the airflow generated by the post-feed blower 72 acts vertically on the surface of the substrate, causing the waste to separate from the substrate.

[0093] In some embodiments, the rear feed assembly 71 includes several groups of parallel and spaced-apart flow wheel mechanisms 711, and there is a non-zero angle between the windward surface of the flow wheel mechanism 711 and the airflow direction generated by the waste removal fan 72.

[0094] like Figure 1 and Figure 8 As shown, the rear feed assembly 71 uses several sets of parallel and spaced-apart flow wheel mechanisms 711 to support the workpiece substrate. It does not require its own power drive and is fed by the power of the substrate itself. There are gaps between adjacent flow wheel mechanisms 711 to allow waste material to fall. In the design of the flow wheel mechanism 711, its supporting surface or windward surface is at an angle to the airflow direction generated by the waste removal fan 72. Therefore, the force exerted by the waste removal fan 72 varies at different positions on the supporting surface of the flow wheel mechanism 711. As a result, different points of the waste material are subjected to different forces, and thus, with the help of leverage, the waste material is accelerated to separate from the substrate.

[0095] In some embodiments, the post-waste collection assembly 4 includes a hopper assembly 41 and a post-waste collection module 42;

[0096] The hopper assembly 41 is located below the post-waste cleaning assembly 7 and is used to collect the waste material removed by the post-waste cleaning assembly 7 into the post-waste collection module 42.

[0097] like Figure 1As shown, the addition of the post-waste collection assembly 4 allows for the separate collection of waste removed by the post-waste cleaning assembly 7, thus avoiding a decrease in negative pressure in the negative pressure chamber 32 caused by sharing the waste collection module 33 with the adsorption waste collection assembly 3.

[0098] In some embodiments, the adsorption and waste collection assembly 3 further includes a waste collection module 33, which is disposed in a negative pressure chamber 32, and a guide plate 323 is provided in the negative pressure chamber 32 to guide the waste into the waste collection module 33.

[0099] The negative pressure chamber 32 is equipped with a sealable assembly port for the waste collection module 33 to enter and exit.

[0100] A transparent sealing plate is installed at the assembly port to observe the amount of waste material contained in the waste collection module 33.

[0101] An independent waste collection module 33 is set up inside the negative pressure chamber 32 to collect waste materials, which facilitates waste cleaning. A guide plate 323 is also set up to facilitate the quick and accurate entry of waste materials into the waste collection module 33. At the same time, an openable assembly port is set on the side of the negative pressure chamber 32 for the disassembly of the waste collection module 33. A transparent sealing plate is used for sealing to ensure the airtightness of the negative pressure chamber 32 and to facilitate the observation of the accumulation of waste materials inside the waste collection module 33.

[0102] In some embodiments, the sidewall of the waste collection module 33 is a transparent plate, which is directly used for sealing the assembly port, and can also achieve the above-mentioned functions.

[0103] In some embodiments, the adsorption and waste collection assembly 3 further includes an air suction and filtration assembly 34, which includes a filter cartridge 341 and a hollow tube 342 that is rotatably disposed inside the filter cartridge 341.

[0104] The filter cartridge 341 is connected to a negative pressure source to create a negative pressure chamber 32;

[0105] A backflush nozzle 343 is connected to the outer periphery of the hollow tube 342. The hollow tube 342 is connected to a controllable high-pressure gas source, which is used to make the backflush nozzle 343 spray high-pressure gas to drive the hollow tube 342 to rotate and remove the waste material attached to the outside of the filter cartridge 341.

[0106] like Figure 2 , Figure 3 and Figure 7 As shown, a suction filter assembly 34 is installed inside the negative pressure chamber 32. The suction filter assembly 34 is connected to the negative pressure fan 31 through a negative pressure pipe to draw negative pressure from the negative pressure chamber 32. At the same time, an exhaust filter 35 is installed at the exhaust port of the negative pressure fan 31 to filter the exhaust.

[0107] The suction and filtration assembly 34 includes a cylindrical filter cartridge 341 that filters the intake air and has a large filtration area to prevent waste from clogging the air inlet of the negative pressure pipe and to ensure that the negative pressure fan 31 can continuously draw negative pressure from the negative pressure chamber 32.

[0108] Meanwhile, a hollow tube 342 is rotatably installed inside the filter cartridge 341, and a backflush nozzle 343 is installed on the outer periphery of the hollow tube 342. The hollow tube 342 is connected to a high-pressure air source through a rotary joint 344. When the outside of the filter cartridge 341 is severely blocked, a high-pressure airflow is introduced into the hollow tube 342, and air is blown outward from the inside of the filter cartridge 341 through the backflush nozzle 343 to clean the blockage of the filter cartridge 341. During the process, the backflush nozzle 343 can push the hollow tube 342 to rotate, which can clean more parts of the outside of the filter cartridge 341.

[0109] In addition to the adsorption and waste removal feeding device disclosed in the above embodiments, the present invention also provides a laser die-cutting machine, including a laser galvanometer assembly 1 and the adsorption and waste removal feeding device of any of the above embodiments.

[0110] The laser galvanometer assembly 1 is arranged at the bearing part of the feed assembly 2 and is used to die-cut the workpiece carried by the bearing part of the feed assembly 2.

[0111] The structure of other parts of this laser die-cutting machine is described in reference to existing technologies and will not be repeated here.

[0112] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0113] The adsorption waste removal feeding device and laser die-cutting machine provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
