Description

Technical Field

[0001] This invention relates to the field of luggage manufacturing and processing technology, and more specifically, to an automated punching and processing equipment for luggage manufacturing. Background Technology

[0002] As an essential storage item for daily travel, suitcases are mostly made of plastic and manufactured in one piece through vacuum forming and stamping processes. To enhance the overall structural strength and aesthetic appeal of the suitcase shell, the surface is often integrally formed with reinforcing ribs, recessed grooves, steps, and other irregularly shaped structures. Due to the limitations of the one-piece molding process, directly drilling holes inside the mold can easily cause defects such as hole deformation and structural tearing. Therefore, the luggage manufacturing industry generally adopts a production process where the entire irregularly shaped suitcase shell is first integrally molded, and then the shell is drilled a second time using drilling equipment to ensure the integrity of the shell and the quality of the drilling.

[0003] In the existing technology, the side punching operation of irregular box shells is mainly completed by special box punching equipment. This type of equipment usually consists of a punching workbench and a punching head set on the workbench. The workbench supports and limits the inner side of the box shell, and the punching head presses down to complete the punching processing at the specified position of the box shell.

[0004] However, the internal support structure of traditional bag punching equipment is usually a fixed flat rigid structure, suitable for supporting and positioning workpieces with flat surfaces. When punching the sides of luggage shells with long, irregular shapes such as reinforcing ribs and recessed grooves, the flat support structure is not easy to fit into the irregular surface of the shell, which can easily lead to uneven support contact, local suspension, and single-point hard contact. This can cause the shell to shift under force and the hole position accuracy to decrease during the punching process. Therefore, there is an urgent need for an automated punching equipment for bag manufacturing to solve the above problems. Summary of the Invention

[0005] This invention provides an automated punching and perforation processing device for luggage manufacturing. By configuring a rigid clamping structure at the far end and a flexible bonding mechanism inside the punching cavity, the overall positioning during punching is more stable and reliable. Simultaneously, it absorbs the impact vibration generated by the downward pressure of the punching head, suppresses resonance in the punching cavity, and, during the feeding process of the luggage shell along the support groove, the linkage air circuit achieves phased coordination between the rigid clamping at the far end and the flexible bonding in the punching area. This improves the support bonding accuracy and overall machine stability during automated punching of irregularly shaped luggage shells, thereby solving the problems mentioned in the background art, namely:

[0006] Luggage cases are typically molded in one piece using vacuum forming or stamping, and their surfaces usually have irregularly shaped structures. The industry generally uses a process of forming first and then punching. However, most existing punching equipment uses flat supports, which can easily affect the punching accuracy due to incomplete fit.

[0007] To achieve the above objectives, the automated punching processing equipment for bag manufacturing includes a main body, which consists of a frame and a processing mechanism mounted on the frame. The processing mechanism includes an outer support mechanism, in which a punching mechanism for punching holes in the bag shell is installed. The outer support mechanism includes two side plates, each with a support groove. The two side plates are connected by a middle support plate and a bottom support plate, forming a punching cavity between the middle support plate and the bottom support plate. A flexible bonding mechanism is installed on the inner wall of the punching cavity, and the flexible bonding mechanism includes an upper flexible pad layer located at the top of the inner cavity of the punching cavity.

[0008] Both of the aforementioned support slots are movably connected to a remote clamping mechanism, which is composed of a clamping member and a connecting structure. When the housing is inserted into the support slot, the housing first squeezes the clamping member, causing the clamping member to rigidly clamp the area of ​​the housing away from the punching cavity. At the same time, the upper part of the clamping member extends into the side plate, forcing the connecting structure to open and supplying gas to the upper flexible pad. As the gas fills, the upper flexible pad gradually expands and adheres to the top surface of the housing, forming a flexible support in the punching area. In the same housing insertion action, staged clamping is achieved sequentially.

[0009] In the above technical solution, by coordinating the remote clamping mechanism and the flexible fitting mechanism inside the punching cavity, and combining the workpiece feeding stroke linkage air circuit on / off structure, the phased coordination of the remote rigid positioning and the flexible adaptive support of the punching area can be achieved in an orderly manner. This buffers the impact vibration of punching, suppresses cavity resonance, improves the clamping stability and fitting support effect of irregular box shells, and thus improves the overall punching processing quality and the stable operation of the equipment.

[0010] Based on this, the punching mechanism includes a driving component fixedly installed on the top of the side plate, and a punching head is assembled at the movable end of the driving component; a guide hole adapted to the punching head is opened on the middle support plate, and a material discharge hole is opened on the bottom support plate, the diameter of the material discharge hole being larger than the diameter of the guide hole.

[0011] Furthermore, the clamping member includes a guide rod, the cross-section of which is a convex structure that is narrower at the top and wider at the bottom; a sliding cavity is provided at the top of the inner cavity of the support groove, the cross-section of which is adapted to the guide rod, the guide rod is slidably disposed in the sliding cavity, and a pressing block is connected to its bottom; the wide part of the guide rod and the top of the inner cavity of the wide part of the sliding cavity are connected by an elastic element.

[0012] Preferably, the connecting structure includes a first airflow cavity and a second airflow cavity formed in the side plate, wherein an external air pump structure is connected in the first airflow cavity.

[0013] The narrow section of the guide rod has a connecting cavity. When the housing extends into the support groove, the housing can push the pressing block, forcing the guide rod to slide in the sliding cavity. During the sliding process, the guide rod can drive the connecting cavity to the position where the first airflow cavity and the second airflow cavity are connected.

[0014] The end of the pressing block facing the opening of the support groove forms a guide opening between it and the inner wall of the support groove.

[0015] In another technical solution, the upper flexible pad layer is composed of a connecting bladder and a facing layer. A central cavity is provided in the middle support plate. The central cavity is connected to the connecting bladder through an input hole. The other end of the central cavity is connected to the second airflow cavity through a connecting pipe.

[0016] The flexible bonding mechanism also includes a lower flexible pad layer, which includes a pad surface layer installed on the surface of the bottom support plate. The surface of the pad surface layer is smooth and has a height difference, and its opening is set to be arc-shaped.

[0017] The surface of the veneer layer has a wavy structure, and the direction of the crests and troughs of the wavy structure matches the direction of the elongated concave and convex features on the side of the casing.

[0018] This technical solution, through the layered arrangement of upper and lower flexible pads, forms a stable and sealed air delivery structure via a central cavity, inlet hole, and connecting pipe. The upper facing layer is designed as a wave-shaped structure that matches the elongated and uneven features of the box shell. Combined with the lower pad with height difference and arc-shaped opening, it achieves layered flexible support and adaptive fitting of the punching area, balanced force support, and improves the adaptability and support and protection performance of punching operations on irregularly shaped box shells.

[0019] In addition, a vent valve is also installed on the central cavity. The vent valve is electrically connected to the punching mechanism so that it can be opened to release pressure according to the signal of the punching mechanism after punching is completed.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. In this automated punching equipment for bag manufacturing, a remote rigid clamping structure is set up to form a clamping support for the side of the box shell that needs to be punched, thereby improving the overall positioning stability during the punching process. At the same time, the flexible bonding mechanism makes the inner wall of the punching cavity a flexible structure, which is different from the original rigid inner wall. When the punching head presses down and generates instantaneous impact vibration, it can effectively absorb the impact load, suppress the resonance of the punching cavity, and improve the stability of the whole machine operation.

[0022] 2. In this automated punching and processing equipment for bag manufacturing, when the bag shell is pushed into the processing mechanism along the support groove of the side plate, it will squeeze the clamping parts of the remote clamping mechanism to produce sliding displacement. This process can activate the air passage of the connecting structure to inflate the upper flexible pad. Through the single action of inserting the bag shell, the clamping parts are used to complete the remote rigid clamping first, and then the upper flexible pad after inflation provides adaptive and tight support to the periphery of the punching area, thereby improving the fitting accuracy of the bag shell support.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] In existing technologies, suitcase shells are mostly manufactured through vacuum forming or stamping, and their surfaces often feature reinforcing ribs and other irregularly shaped structures. Due to limitations in material tensile deformation, the industry generally adopts a process of forming first and then punching. The worktable support of existing luggage punching equipment is mostly a flat, rigid structure, which makes it difficult to fully conform to the irregularly shaped shell, resulting in uneven contact during punching and consequently affecting the accuracy of the holes.

[0044] In view of this, see Figures 1-11 As shown, the present invention provides an automated punching processing equipment for bag manufacturing, including a machine body 1. The machine body 1 is composed of a frame 10 and a processing mechanism 11 installed on the frame 10. The processing mechanism 11 includes an outer support mechanism 13, and a punching mechanism 12 for punching holes in the box shell is assembled in the outer support mechanism 13.

[0045] The external support mechanism 13 includes two side plates 131, each of which has a support groove 134. The two side plates 131 are connected by a middle support plate 132 and a bottom support plate 133. A punching cavity is formed between the middle support plate 132 and the bottom support plate 133. The inner wall of the punching cavity is equipped with a flexible bonding mechanism 3, which can form a flexible buffer and shock absorption for the punching area. The flexible bonding mechanism 3 includes an upper flexible pad 32 located at the top of the inner cavity of the punching cavity.

[0046] Both support grooves 134 are movably connected to remote clamping mechanisms 2, which can be flexibly triggered and linked with the workpiece insertion action. The remote clamping mechanism 2 is composed of clamping member 21 and connecting structure 210. When the box shell extends into the support groove 134, the box shell first squeezes the clamping member 21, so that the clamping member 21 rigidly clamps the area of ​​the box shell away from the punching cavity, ensuring the overall positioning stability of the box shell and reducing displacement deviation during the punching process. During this process, the upper part of the clamping member 21 extends into the side plate 131, forcing the connecting structure 210 to open. The air passage is automatically opened by mechanical linkage, and gas is delivered to the upper flexible pad 32. As the gas is filled, the upper flexible pad 32 gradually expands and fits the top surface of the box shell, which can reduce the defects of uneven contact of rigid support and form uniform flexible support in the punching area.

[0047] The aforementioned punching mechanism 12 has the same structural configuration and core function as conventional punching devices in the prior art. Both mechanisms use a drive component to drive the punching component to complete the punching action. (See reference...) Figure 4 and Figure 7 As shown, the driving component 121 (which may be a cylinder structure) is used as the power source for the punching action and is fixedly installed on the top of the side plate 131. The punching head 122 is assembled on the movable end of the driving component 121. The guide hole opened on the middle support plate 132 is adapted to the outer dimensions of the punching head 122 and is used to limit the movement trajectory of the punching head 122. The material discharge hole opened on the bottom support plate 133 corresponds to the waste discharge structure in the prior art, and its diameter is set to be larger than the diameter of the guide hole, forming a corresponding fit between the upper and lower parts.

[0048] Once the housing is completely and stably placed, the punching mechanism 12 begins operation. After receiving the operation signal, the drive component 121's movable end drives the punching head 122 to move downwards in the vertical direction. During its downward movement, the punching head 122 passes through the guide hole on the middle support plate 132, causing it to act on the preset punching position on the housing, thus completing the punching process. After the punching process is completed, the waste material generated by punching falls through the guide hole on the middle support plate 132 to the discharge hole on the bottom support plate 133 under its own gravity. Since the diameter of the discharge hole is larger than that of the guide hole, the waste material can be smoothly discharged outside the equipment through the discharge hole. Subsequently, the movable end of the drive component 121 drives the punching head 122 to move upwards in the vertical direction, returning to the initial position, waiting for the next punching operation signal, thus completing a single punching cycle.

[0049] In conjunction with the overall operation of the equipment body 1, the box shell completes the loading and unloading conveying operation through an automated gripper (using existing technology, which will not be elaborated here). The gripper completes the spatial position calibration in advance, so that the travel trajectory of the box shell entering and exiting the support groove 134 remains fixed, providing regular workpiece input conditions for the orderly operation of the internal mechanical linkage structure of the equipment.

[0050] The clamping member 21 is disposed in the cavity of the support groove 134. The clamping member 21 includes a guide rod 211 with a convex cross-section. The guide rod 211 is vertically slidably assembled in the sliding cavity 213 at the top of the support groove 134. The lower end of the guide rod 211 is fixedly connected to a pressing block 212. The guide rod 211 has a structure that is narrow at the top and wide at the bottom. An elastic member 216 (preferably a spiral spring) is connected between the wide part of the guide rod 211 and the lower top wall of the sliding cavity 213. The whole structure forms a vertically elastic sliding assembly structure. In the overall structure, the position of the distal clamping mechanism 2 is located outside the punching operation area. During the operation stage, it can form a lateral limiting and supporting effect on the side of the box shell, so that the box shell maintains a stable spatial placement state during the punching process.

[0051] The connecting structure 210 is embedded inside the solid structure of the side plate 131. The first airflow chamber 214 is connected to an external air supply pump (using existing technology). The second airflow chamber 215 is connected to the central cavity 321 inside the middle support plate 132 through the connecting pipe 325. The connecting cavity 217 in the narrow part of the guide rod 211 is located beside the docking path of the first airflow chamber 214 and the second airflow chamber 215. The vertical sliding displacement of the guide rod 211 realizes the connection and disconnection of the passage between the cavities.

[0052] The upper flexible pad 32 is integrally assembled on the top inner wall of the punching cavity. The connecting bladder 322 is fitted to the bottom of the inner cavity of the punching cavity. One side of the facing layer 323 is connected to the surface of the connecting bladder 322, and the other side faces downward toward the machined surface of the shell. An input hole 324 is opened at the bottom of the inner cavity of the middle cavity 321. The input hole 324 is used to connect the middle cavity 321 and the connecting bladder 322 to form a sealed inflation passage. The connecting bladder 322 can be made of aging-resistant nitrile rubber, and the facing layer 323 can be made of high-elasticity polyurethane material, which is suitable for long-term working conditions of repeated inflation deformation and bonding with irregular surfaces.

[0053] The lower flexible pad 31 is fixedly installed on the upper surface of the bottom support plate 133, located at the bottom of the punched cavity and arranged vertically opposite to the upper flexible pad 32. The pad surface layer 311 is preferably made of high-resilience silicone material. The height difference of the pad surface layer 311 is preferably controlled between 2mm and 3mm. This size matches the conventional concave and convex structure of the suitcase shell and the shell wall thickness parameters. The staggered surface shape of the pad surface layer 311 can adapt to the subtle structural differences at the bottom of the suitcase. Combined with the arc-shaped structure at the port, it is compatible with the movement trajectory of the suitcase shell conveyed by the automated gripper and will not cause movement interference during the axial insertion of the suitcase shell into the support groove 134.

[0054] Specifically, the rigid inner wall of the punching cavity is replaced by a flexible bonding mechanism 3. The flexible bonding mechanism 3 has the basic characteristic of elastic deformation. The instantaneous impact load and mechanical vibration generated by the punching head 122 pressing down can be transmitted and buffered through the flexible bonding mechanism 3, which adjusts the vibration transmission efficiency inside the punching cavity, changes the conditions for resonance in the punching cavity, and thus maintains the stability of the overall operation of the equipment.

[0055] Furthermore, the opening of the lower flexible pad 31 is set as an arc-shaped transition structure, which corresponds to the insertion direction of the box shell. The end face of the pressing block 212 facing the port of the support groove 134 and the inner wall of the support groove 134 form a guide opening. The guide opening can guide the entering box shell and correct its position. Under normal working conditions, when the box shell does not enter the support groove 134, a fixed reserved gap is maintained between the bottom of the pressing block 212 and the bottom of the inner cavity of the support groove 134. This gap can expand the inlet capacity of the support groove 134, adapt to the multi-angle entry posture of the workpiece conveyed by the automated gripper, and the gap layout only acts on the workpiece introduction stage and will not change the force support foundation of the pressing block 212 after being pressed.

[0056] During operation, the automated gripper, having completed its position calibration, smoothly transports the housing along the guide port to the inside of the support groove 134. The side wall of the housing gradually contacts and pushes against the pressing block 212, causing the guide rod 211 to slide vertically upward along the sliding cavity 213. The elastic element 216 undergoes compression deformation simultaneously. During the displacement of the guide rod 211, the connecting cavity 217 moves synchronously, so that the first airflow cavity 214 and the second airflow cavity 215 form a connected air passage through the connecting cavity 217. The airflow output by the external air pump flows sequentially through the connecting pipe 325, the middle cavity 321, and the input hole 324 before entering the connecting bladder 322. The connecting bladder 322 inflates and expands, causing the wave-shaped facing layer 323 to adhere to the peripheral surface of the perforated area of ​​the housing. The lower flexible pad layer 31 simultaneously supports the bottom foundation structure of the housing, sequentially completing the rigid clamping at the far end and the flexible support of the perforated area. Subsequently, the driving component 121 drives the punching head 122 downward to complete the perforation processing of the housing.

[0057] In addition, the overall lifting stroke of the clamping component 21 is positively correlated with the gas flow section inside the air passage. The difference in the basic wall thickness parameters of the case shell itself is small, but the greater the thickness difference of the concave and convex structure of the case shell side wall, the higher the lifting stroke value generated by the clamping component 21 under pressure. The flow area of ​​the air passage increases synchronously, and the gas flow rate entering the upper flexible pad 32 changes accordingly. The expansion amount of the flexible pad is adjusted synchronously. According to the degree of protrusion of the irregular concave and convex shape of the case, the corresponding fitting support force can be matched to adapt to the support needs of different shaped cases.

[0058] Correspondingly, as the box shell is pushed into the processing mechanism 11 by the automated gripper, the side wall of the box shell continuously squeezes the clamping component 21 and generates vertical sliding displacement. The mechanical linkage structure simultaneously completes the automatic air circuit conduction. Step-by-step clamping operation is achieved by relying on a single workpiece insertion action. The clamping component 21 at the outer far end position first completes rigid limiting and fixing. The upper flexible pad 32 on the inner side of the punching cavity is subsequently inflated and expanded to fit. The middle flexible support area maintains a reasonable and safe distance from the punching operation point and only acts on the periphery of the punching area. The layered and staggered clamping layout can adapt to the long strip-shaped irregular concave and convex surface of the box shell, improving the uniformity of the fit of the overall support contact of the box shell.

[0059] Subsequently, in actual operation, the upper flexible pad 32 at the top of the punching cavity can fully fit and contact the peripheral surface of the punching area of ​​the box shell. A small gap can be left between the lower flexible pad 31 at the bottom of the punching cavity and the bottom surface of the box shell. The force of the punching operation is mainly transmitted downward in the vertical direction. The flexible support structure covering the top can evenly bear the dispersed stress generated by punching, which meets the stress conditions for the punching and forming of the box. There is no main force transmission requirement in the lower position. The existence of this gap will not affect the positioning effect of the box and the punching quality. It can be normally adapted and used during continuous operation of the equipment.

[0060] In addition, the veneer layer 323 is designed as a continuous wave-shaped structure, and the peaks and troughs of the wave-shaped structure extend in the same direction as the long strip-shaped concave and convex features on the side of the box shell. This helps to increase the effective contact area between the flexible structure and the irregular box shell, so that the flexible support force is evenly distributed on the side wall of the box, which is suitable for the irregular structural features of the blister-formed and stamped one-piece molded bag shell.

[0061] The middle cavity 321 serves as a transfer air passage cavity connecting the second airflow cavity 215 and the upper flexible pad 32 connecting bag 322. A vent valve 326 is fixedly installed outside the middle cavity 321. The vent valve 326 is an air passage pressure relief adjustment component. The vent valve 326 forms an electrical matching arrangement with the punching mechanism 12. It can adjust its own on / off and conduction opening degree according to the working condition signal of the punching mechanism 12, so as to realize the timing coordination of the air passage pressure relief action and the punching process.

[0062] The electrical control module (not shown in the figure) of the punching mechanism 12 is electrically connected to the drive end of the vent valve 326 through a wire (using existing technology). The punching mechanism 12 is equipped with position sensing components, which can collect the movement stroke and station status of the punching head 122 in real time. Using a weak electrical signal as the transmission carrier, the station information of punching completion is synchronously transmitted to the vent valve 326. Through the real-time feedback transmission mode of electrical signals, the linkage logic between punching action and pressure relief action is established to realize the automated timing coordination between processes.

[0063] During operation, after the punching head 122 of the punching mechanism 12 descends to complete the punching operation of the housing and rises back to the preset initial position, the sensing components inside the punching mechanism 12 generate a corresponding electrical signal and send it to the vent valve 326 (the opening passage of the vent valve 326 is larger than the air inlet passage of the connecting cavity 217). After receiving the electrical signal, the vent valve 326 increases its own conduction diameter, and the gas passage inside the middle cavity 321 maintains a large flow state. The compressed air stored inside the upper flexible pad 32 is discharged outward through the vent valve 326. Under synchronous operation, the automated gripper receives... The machine control command drives the processed housing to move rapidly away along the axis of the support groove 134. The housing gradually detaches from the lateral pressure of the clamping block 212 on the clamping member 21. The clamping member 21 as a whole falls back to its original position under the action of the elastic member 216. The guide rod 211 follows the displacement and drives the connecting cavity 217 to detach from the communication area between the first airflow cavity 214 and the second airflow cavity 215. The air intake path is gradually cut off. The overall air path structure and clamping components of the equipment return to the normal assembly state, waiting for the automated gripper to transport the next housing to be processed into the work station.

[0064] Working principle:

[0065] First, the box body completes the standardized loading and unloading conveying operation of the box shell through the automated gripper (not shown in the diagram) with the preset calibration trajectory. The box shell is smoothly introduced into the equipment along the guide port of the support groove 134. During the process of the box shell extending into the support groove 134, it continuously presses against the pressing block 212, pushing the guide rod 211 to slide upward along the sliding cavity 213 and compress the elastic element 216. The displacement of the guide rod 211 synchronously drives the connecting cavity 217 to move, so that the first airflow cavity 214 and the second airflow cavity 215 form a communication channel. The compressed air delivered by the external air pump can be continuously introduced into the interior of the upper flexible pad 32 through the connecting pipe 325, the middle cavity 321, and the input cavity.

[0066] Furthermore, after the connecting bladder 322 of the upper flexible padding layer 32 is inflated, the wavy facing layer 323 on the surface adapts to the long strip-shaped concave-convex structure on the side of the box shell, forming a flexible support structure that cooperates with the lower flexible padding layer 31 at the bottom. At the same time, the outer far end clamping mechanism 2 forms a rigid limiting support for the side end of the box shell.

[0067] After receiving the work instruction, the punching mechanism 12 drives the punching head 122 to move vertically downwards, passing through the guide hole of the middle support plate 132 to complete the box shell punching process. During the operation, the flexible fitting mechanism 3 on the inner wall of the punching cavity can buffer and transmit the impact load generated by punching, adjust the vibration transmission form of the cavity, and maintain the stability of the overall machine operation.

[0068] After a single punching process is completed, the punching head 122 returns to its original position, and the built-in sensing element of the punching mechanism 12 outputs an electrical signal. After receiving the signal, the electrically connected vent valve 326 expands the conduction diameter, which accelerates the discharge rate of gas inside the middle cavity 321 and the upper flexible pad 32, thereby realizing the rapid retraction of the flexible support structure.

[0069] Finally, the automated gripper synchronously performs the material extraction action, causing the processed box shell to quickly detach axially from the support groove 134. The box shell releases the squeezing limit on the pressing block 212, and the elastic element 216 rebounds, driving the guide rod 211 and the pressing block 212 to move downward and reset as a whole. The connecting cavity 217 is misaligned and disconnects the connection between the two sets of airflow cavities, and the air intake path is cut off. All linkage structures of the equipment return to their initial normal state, waiting for the next set of box shells to enter the work station, thereby realizing continuous cycle automated punching processing.

[0070] It should be noted that the punching and drilling mentioned above refer to the same processing procedure, and their technical meanings are consistent.
