Description

Technical Field

[0001] This application relates to the field of automated mattress production technology, and in particular to a mattress assembly device. Background Technology

[0002] The main component of a spring mattress is the spring mesh. The spring mesh is typically manufactured by first connecting multiple springs sequentially to form pocket spring strings, and then welding these strings side-by-side. For example, the connecting fabric between two adjacent springs in a spring string serves as the welding point. A welding knife and welding head work together to weld the fabric at the welding points of adjacent rows of spring strings together, thus connecting and securing the two rows of spring strings.

[0003] Typically, the welding positions between adjacent rows of spring strings are staggered. During welding, the first row of spring strings is laid first, and the first welding position of the spring strings is welded; then the second row of spring strings is laid, and the second welding position of the spring strings is welded, with the first and second welding positions staggered. This welding method can achieve the welding and forming of the spring bed mesh; however, it still suffers from problems such as insufficient welding speed and low production efficiency. Utility Model Content

[0004] To solve at least one of the above-mentioned technical problems, this application provides a bed net assembly device that can weld multiple bed nets simultaneously, thereby improving production efficiency. The technical solution adopted is as follows.

[0005] The bed frame assembly equipment provided in this application includes a welding knife mechanism, a welding head mechanism, a limiting component, and a feeding component. The welding knife mechanism includes two sets of welding knife assemblies, each of which includes multiple welding knives extending along a first direction. The welding knives form multiple welding stations along the first direction. The welding knives in the same set are spaced apart along a second direction, and the welding knives in different sets are alternately arranged along the second direction. The welding head mechanism is located on one side of the welding knife mechanism along a third direction. The welding head mechanism includes multiple welding head assemblies spaced apart along the second direction. Each welding head assembly includes an ultrasonic welding head, which can move along the third direction to cooperate with any set of welding knife assemblies to complete the welding of multiple welding stations. The limiting component is located on the side of the welding knife mechanism opposite to the welding head mechanism along the third direction. The limiting component forms a multi-layer forming channel for placing spring strings. The multi-layer forming channels are distributed along the first direction and correspond one-to-one with the welding stations. The feeding component is used to transport the spring strings to the welding stations along the second direction.

[0006] In some embodiments of this application, the limiting component includes at least a first receiving member, which extends along a second direction and has forming channels on both sides along a first direction, the forming channels being used for the welded bed mesh to pass through.

[0007] In some embodiments of this application, the limiting component further includes a second receiving member and a third receiving member extending along a second direction.

The space between the first receiving member and the second receiving member, and the space between the third receiving member and the first receiving member, define the forming channel. The distance between at least two of the first receiving member, the second receiving member, and the third receiving member is adjustable.

[0008] In some embodiments of this application, the limiting component further includes a plurality of support members spaced apart along a second direction. The support members are disposed on the side of the receiving member facing the welding head mechanism, and are disposed in the gap between adjacent welding blades. The support members extend into the welding station along a third direction.

[0009] In some embodiments of this application, the receiving member includes a limiting plate, the support member is disposed on the limiting plate, and the spacing of the plurality of support members along the second direction is adjustable.

[0010] In some embodiments of this application, the limiting plate is provided with a guide rail extending along a second direction, the support member includes a flexible part and a connecting part connected to each other, the connecting part is engaged with the guide rail and is movable along the guide rail, the flexible part extends from between two adjacent welding knives along a third direction, the flexible part is provided with a buffer notch, the buffer notch divides the flexible part into two parts along the second direction, when the welding head and the welding knife cooperate to weld, the side of the welding head contacts the flexible part.

[0011] In some embodiments of this application, the feeding assembly forms multiple feeding channels in a first direction, and each feeding channel is correspondingly provided to the welding station.

[0012] In some embodiments of this application, the feeding assembly includes conveyors arranged in pairs at intervals in a second or third direction, forming at least a portion of the feeding channel between the pairs of conveyors, and at least one of the conveyors being an active member, the active member including at least one of a dial wheel, a roller, and a conveyor belt, the active member being movable to transport the spring string.

When the dial wheel is located in the feeding channel, the dial wheel is segmented in a first direction corresponding to the multi-layer feeding channel.

[0014] In some embodiments of this application, the feeding assembly further includes a guide structure disposed on the feeding side of the conveyor, the guide structure including a first guide component disposed radially on both sides of the spring string, the space between two sets of the first guide components forming the feeding channel; and / or, the guide structure includes a second guide component disposed radially on the end face of the spring string, the side of the second guide component facing the spring string forming part of the feeding channel.

[0015] In some embodiments of this application, the welding knife assembly is movable along a third direction, and the welding knife assembly can also be inserted or withdrawn from between adjacent springs of the spring string along a first direction. When the welding knife assembly is withdrawn from between the springs and moved along a third direction to the side of the spring string facing the welding head mechanism, the welding knife assembly can push the spring string towards the forming channel along the third direction.

[0016] In some embodiments of this application, the welding knife assembly includes a first mounting base and a welding knife, one end of a plurality of welding knives being rotatably connected to the first mounting base, and when the welding knife engages with the welding head assembly, the welding knife can rotate relative to the first mounting base so that the welding knife is in contact with the welding head assembly.

[0018] In some embodiments of this application, the push rod assembly is configured as two sets, with the push rods of the two sets of push rod assemblies arranged alternately along a second direction. The positions of the push rods correspond to the two sets of welding knife assemblies respectively. After one set of welding knife assemblies is pulled out from between the spring strings along a first direction, the push rod assembly in the corresponding position pushes the spring strings toward the forming channel through movement in the first direction and a third direction, so that when the welding knife assembly is reset, it can switch to the side of the spring string closer to the welder's position.

The second drive member can drive the welding head mechanism to move along the first track, and the welding head mechanism can move in the first direction to avoid the feeding assembly.

[0022] In some embodiments of this application, the welding head assembly is movable along a second direction to connect the welding head assembly to the welding knife at different positions in the same welding knife mechanism to complete welding at different positions.

[0023] The embodiments of this application have at least the following beneficial effects: Spring strings are laid at multiple welding stations using a feeding assembly. When the welding head mechanism approaches the welding knife mechanism, the welding head assembly and the welding knife assembly are connected along a third direction, enabling the fabric at the welding positions of adjacent rows of spring strings to be welded and fixed together. Since multiple welding stations are provided in the extension direction of the welding knife, multiple bed nets in the first direction can be welded simultaneously when the welding knife and welding head are connected. Thus, each welding action performed by the welding head can simultaneously complete the welding of spring strings from multiple bed nets, thereby helping to increase welding speed and improving the efficiency of bed net manufacturing.

[0050] Please see Figures 1 to 4 This application provides a bed frame assembly device 1000, including a welding knife mechanism 100, a welding head mechanism 200, a limiting component 300, and a feeding component 400. The welding knife mechanism 100 includes two sets of welding knife assemblies 110, each of which includes multiple welding knife components along a first direction (e.g., ...). Figure 1 The welding knife 111 extends along the z-direction (as shown), and the welding knife 111 forms multiple welding stations 112 along the first direction. The welding knives 111 in the same group extend along the second direction (as shown). Figure 1 The welding blades 111 are arranged at intervals along the second direction (as shown in the x-direction), and different groups of welding blades 111 are alternately arranged along the second direction. The welding head mechanism 200 is arranged along the third direction (as shown in the x-direction). Figure 1 The welding head mechanism 200 (as shown in the y-direction) is located on one side of the welding knife mechanism 100. The welding head mechanism 200 includes multiple welding head assemblies 210 spaced apart along the second direction. Each welding head assembly 210 includes an ultrasonic welding head 211, which can move along a third direction to cooperate with any set of welding knife assemblies 110 to complete welding at multiple welding stations 112. A limiting assembly 300 is located on the side of the welding knife mechanism 100 opposite to the welding head mechanism 200 along the third direction. The limiting assembly 300 forms a multi-layer forming channel 301 for placing the spring string 2000. The multi-layer forming channels 301 are distributed along the first direction and correspond one-to-one with each welding station 112. The feeding assembly 400 is used to transport the spring string 2000 to the welding station 112 along the second direction.

[0051] In this application, a feeding assembly 400 is used to lay spring strings 2000 at multiple welding stations 112. When the welding head mechanism 200 approaches the welding knife mechanism 100, the welding head assembly 210 and the welding knife assembly 110 are connected in a third direction, which can weld and fix the fabric at the welding positions of adjacent rows of spring strings 2000. Since multiple welding stations 112 are provided in the extension direction of the welding knife 111, when the welding knife 111 is connected to the ultrasonic welding head 211, multiple bed nets 3000 in the first direction can be welded simultaneously. Thus, each time the ultrasonic welding head 211 performs a welding action, it can simultaneously complete the welding of spring strings 2000 of multiple bed nets 3000, thereby helping to improve the welding speed and thus improve the manufacturing efficiency of the bed nets 3000. Optionally, the welding head 211 can also adopt other welding methods besides ultrasonic welding, such as a thermal welding head. Here, the ultrasonic welding head 211 is used as an example for explanation. This application does not limit the specific type of welding head.

[0052] by Figure 1 For example, the first direction is vertical, and the first, second, and third directions are set perpendicular to each other. Two welding stations 112 are formed on one side of the welding knife mechanism 100, distributed vertically. Correspondingly, the limiting component 300 forms two layers of forming channels 301. Each layer of forming channel 301 is used to place partially welded spring strings 2000. When a certain number of spring strings 2000 are all welded, they can form a bed net 3000. Thus, the bed net assembly equipment 1000 can weld two bed nets 3000 simultaneously, thereby improving the production efficiency of the bed net 3000. Of course, in other examples, three or four welding stations 112 can be set along the first direction, and the first direction can also be horizontal; this is not limited here. The following explanation will continue with the example shown in the attached figure (z-direction is the first direction) and the two layers of forming channels 301.

[0053] Optionally, the two sets of welding knife assemblies 110 alternately weld different welding positions of the spring string 2000. Specifically, please refer to... Figure 1 and Figure 10 The welding of one of the 3000 mesh mattresses will be used as an example for explanation. Figure 10 In the diagram, each welding position in each row of 2000 spring strings is identified by indicator lines with numerical numbers, and... Figure 10 The laying sequence of each spring string 2000 in the bed net 3000 is also indicated by arrow-shaped guide lines. For example... Figure 1 as well as Figure 10As shown, in a row of spring strings 2000, the welding positions can be further divided into a first welding position 910 (i.e., the welding position marked by the even-numbered indicator line) and a second welding position 920 (i.e., the welding position marked by the odd-numbered indicator line). The first welding position 910 and the second welding position 920 alternate with each other. The spring strings 2000 in the first row and the spring strings 2000 in the second row are welded together through the first welding position 910, and the spring strings 2000 in the second row and the spring strings 2000 in the third row are welded together through the second welding position 920.

[0054] The feeding assembly 400 sequentially lays out rows of spring strings 2000. Starting from the second row of spring strings 2000, after each row of spring strings 2000 is laid out, the welding head assembly 210 and the welding knife assembly 110 weld the laid-out spring strings 2000 together with the previous row of spring strings 2000. The two sets of welding knife assemblies 110 correspond to the first welding position 910 and the second welding position 920 of the spring strings 2000, respectively. During the welding process, firstly, the welding knife 111 of the first set of welding knife assemblies 110 (hereinafter defined as the first welding knife 1111) corresponds to the first welding position 910. The feeding assembly 400 lays out the even-numbered rows of spring strings 2000 on the odd-numbered rows of spring strings 2000. The welding head assembly 210 presses against the welding station 112. The welding head assembly 210 and the first welding knife 1111 clamp and weld the first welding positions 910 of the two rows of spring strings 2000 together. Next, the welding blade 111 (hereinafter defined as the second welding blade 1112) of the second welding blade assembly 110 corresponds to the second welding position 920. The feeding assembly 400 lays the odd-numbered rows of spring strings 2000 on the even-numbered rows of spring strings 2000. The welding head assembly 210 presses against the welding position 112. The welding head assembly 210 and the second welding blade 1112 clamp and weld the two rows of spring strings 2000 at the second welding position 920 together. On the one hand, the feeding assembly 400 can continuously lay a row of spring strings 2000, and the welding head assembly 210 performs welding after a row of spring strings 2000 is laid. On the other hand, the two sets of welding blade assemblies 110 alternately cooperate with the welding head assembly 210 to complete the welding, thereby improving the production efficiency of the bed mesh 3000.

[0055] In some embodiments, please refer to Figure 3 The welding head assembly 210 includes a welding head 211 and a third driving member 212. The third driving member 212 drives the welding head 211 to extend and connect with the welding knife 111 to achieve welding. The third driving member 212 also drives the welding head 211 to retract and separate from the welding knife 111.

[0056] In some embodiments, please combine Figures 2 to 4The limiting component 300 includes at least a first receiving member 310, which extends along a second direction. Forming channels 301 are formed on both sides of the first receiving member 310 along a first direction, allowing the welded bed mesh 3000 to pass through. Using the first receiving member 310, the space on the side of the welding knife mechanism 100 away from the welding station 112 can be divided into upper and lower layers, each forming a forming channel 301. The welded spring strings 2000 can be stored in the forming channels 301, freeing up space in the welding station 112 for laying a new row of spring strings 2000, thus avoiding interference with the unwelded spring strings 2000. The separation of the two forming channels 301 by the first receiving member 310 prevents mutual interference between the two layers of bed mesh 3000 during the welding process, improving the reliability of the bed mesh 3000 welding process.

[0057] For example, the first receiving member 310 may include at least one of a platform, a baffle, a partition, and a conveyor belt. Figure 3 In one embodiment, the first receiving member 310 is configured as a baffle (limiting plate).

[0058] In some embodiments, the limiting component 300 further includes a second receiving member 320 and a third receiving member 330 extending along a second direction. The second receiving member 320 and the third receiving member 330 are respectively spaced apart on both sides of the first receiving member 310 along a first direction. The space between the first receiving member 310 and the second receiving member 320, and the space between the third receiving member 330 and the first receiving member 310, define a forming channel 301. The distance between at least two of the first receiving member 310, the second receiving member 320, and the third receiving member 330 is adjustable. By defining the forming channel 301 between the second receiving member 320, the third receiving member 330, and the first receiving member 310, the sealing and independence of each forming channel 301 can be improved, interference between the forming channel 301 and other components can be avoided, and the welded spring string 2000 can be placed in the forming channel 301, thereby improving the safety and reliability of the bed net 3000 manufacturing process. Adjusting the spacing between the first receiving part 310, the second receiving part 320, and the third receiving part 330 helps to adjust the layer height of the forming channel 301, thereby accommodating spring strings 2000 of different heights and improving the adaptability to the production of bed nets 3000 of different specifications.

[0059] Optionally, the second receiving member 320 is disposed above the first receiving member 310 and forms a first forming channel 301 with the first receiving member 310; the third receiving member 330 is disposed below the first receiving member 310 and forms a second forming channel 301 with the first receiving member 310. The height of one of the forming channels 301 can be adjusted, or the height of both forming channels 301 can be adjusted.

[0060] For example, please refer to Figure 4 The limiting component 300 also includes an adjusting component 350, which includes a guide frame 351 and an adjusting screw 352. The guide frame 351 extends along a first direction and has a slider 353 that can move along the first direction. The slider 353 is connected to the second receiving member 320, and the fixed end of the guide frame 351 is connected to the first receiving member 310. The adjusting screw 352 is also connected to the movable slider 353. By rotating the adjusting screw 352, the position of the slider 353 on the guide frame 351 is adjusted, thereby causing the second receiving member 320 to move along the first direction and adjusting the distance between the second receiving member 320 and the first receiving member 310, thus adjusting the layer spacing of the first forming channel 301. Similarly, in other examples, the adjusting component 350 can also connect the first receiving member 310 and the third receiving member 330 to adjust the layer spacing of the second forming channel 301. Alternatively, the adjusting component 350 can be connected to the second receiving member 320 and the third receiving member 330, simultaneously adjusting the layer spacing between the first forming channel 301 and the second forming channel 301. The connection method of the adjusting component 350 can be flexibly set according to the actual situation, and no specific limitation is made here.

[0061] In some embodiments, the limiting component 300 further includes a plurality of support members 340 spaced apart along a second direction. The support members 340 are disposed on the side of the receiving member facing the welding head mechanism 200, and are disposed in the gaps between adjacent welding blades 111. The support members 340 extend into the welding station 112 along a third direction. By extending the support members 340 into the welding station 112, the spring string 2000 laid on the welding station 112 can be supported to ensure the stability of the spring string 2000 during the welding process. On the other hand, by interleaving the support members 340 and the welding blades 111, mutual interference between the support members 340 and the welding blades 111 can be avoided, and the space of the welding station 112 can be fully utilized, making the arrangement of the support members 340 and the welding blades 111 more compact.

[0062] In some embodiments, the receiving member includes a limiting plate, and the support member 340 is disposed on the limiting plate. The spacing between the multiple support members 340 along the second direction is adjustable. For spring strings 2000 of different specifications and sizes (e.g., different spring arrangement densities, different spring diameters), by adjusting the spacing between the multiple support members 340, each support member 340 can provide support corresponding to the position of each spring, thereby improving the stability of the support and the adaptability to spring strings 2000 of different specifications.

[0063] In some embodiments, the limiting plate is provided with a guide rail 311 extending along a second direction. The support member 340 includes a flexible portion 341 and a connecting portion 342 connected to each other. The connecting portion 342 is engaged with the guide rail 311 and is movable along the guide rail 311. The flexible portion 341 extends in a third direction between two adjacent welding blades 111. The flexible portion 341 is provided with a buffer notch 3411, which divides the flexible portion 341 into two parts along the second direction. When the welding head 211 and the welding blade 111 are engaged for welding, the side of the welding head 211 contacts the flexible portion 341. By utilizing the interlocking action of the guide rail 311 and the connecting portion 342, the support member 340 can be easily installed on the limiting plate, improving the installation efficiency of the support member 340. In some embodiments where the welding head mechanism 200 and the support member 340 are relatively compact, the distance between two adjacent support members 340 along the second direction is less than the width of the welding head assembly 210. When the welding head assembly 210 approaches the welding knife 111, there is a risk of scratching due to contact or friction between the side wall of the welding head 211 of the welding head assembly 210 and the support member 340. Therefore, the protruding end of the support member 340 is set as a flexible part 341, and the flexible part 341 is provided with a buffer notch 3411. In this way, when the welding head assembly 210 approaches the welding knife 111, the side of the welding head assembly 210 can contact the flexible part 341. Two adjacent welding head assemblies 210 press the flexible part 341 along the second direction. The buffer notch 3411 can provide a certain amount of deformation to the flexible part 341. On the one hand, it ensures that the welding head assembly 210 can be inserted from the gap between two adjacent support members 340 so that the welding knife 111 can be connected. On the other hand, it avoids the side of the welding head assembly 210 from rubbing against the support member 340, thereby improving the reliability of the welding head mechanism 200.

[0064] In some embodiments, please refer to Figure 5 and Figure 6The feeding assembly 400 forms multiple feeding channels 401 in the first direction, and each feeding channel 401 is correspondingly set to a welding station 112. By setting multiple feeding channels 401 in the feeding assembly 400, each feeding channel 401 can correspond one-to-one with each welding station 112, thereby realizing simultaneous feeding. This can improve the efficiency of laying the spring string 2000 on the one hand, and avoid the feeding assembly 400 from using a reciprocating movement along the first direction to achieve feeding on the other hand, which helps to simplify the feeding action of the feeding assembly 400 and improve the reliability of the spring string 2000 laying process.

[0065] In some embodiments, the feeding assembly 400 includes conveyors 410, which are arranged in pairs at intervals in a second or third direction, forming at least a partial feeding channel 401 between the pairs of conveyors 410. At least one conveyor 410 is a drive member, which includes at least one of a turntable, a roller, and a conveyor belt. The drive member moves to transport the spring string 2000. The movement of the spring string 2000 is powered by the rotation of the drive member and the friction between the surface of the drive member and the surface of the spring string 2000, thereby realizing the laying action of the spring string 2000. The drive member can be in the form of a turntable (e.g., a turntable). Figure 5 (As shown in the example), a groove 412 is formed between adjacent pawls 411 of the dial wheel, which can engage with the outer periphery of the spring. Under the rotation of the dial wheel, it conveys the spring string 2000. Of course, rollers or conveyor belts can also be used. In the paired conveyor components 410, both can be set as driving components, that is, both conveyor components 410 are powered. Alternatively, in other examples, one conveyor component 410 can be set as the driving component and the other as the driven component. No specific limitation is made here.

[0066] In some embodiments, please refer to Figure 6 The conveyor components 410 are configured in pairs, with the driving component being a set of dial wheels. One pair of dial wheels is located at the output end of the feeding channel 401, and the other pair is located at the input end of the feeding channel 401 or within the feeding channel 401. By setting two sets of conveyor components 410, power can be provided for conveying the spring string 2000 at the input end, output end, or within the feeding channel 401, further improving the stability and reliability of the spring string 2000 during the feeding process. When the dial wheels are located within the feeding channel 401, the dial wheels are segmented in the first direction corresponding to the multi-layer feeding channel 401 (e.g., ...). Figure 6 (As shown). Thus, each layer of the feeding channel 401 has a dial wheel, which can simultaneously transport the spring strings 2000 of each layer. Furthermore, the segmented dial wheels can avoid the partition structure between the multiple layers of feeding channels 401, making the structure of the feeding assembly 400 more compact.

[0067] In some embodiments, the feeding assembly 400 includes two sidewall structures defining a feeding channel 401. The distance between the two sidewall structures is adjustable. Pairs of conveying members 410 are respectively disposed on the two sidewall structures, thus the distance between the pairs of conveying members 410 is also adjustable to meet the conveying requirements of spring strings 2000 of different diameters. Specifically, the feeding assembly 400 may be equipped with a lead screw, one end of which is fixedly connected to one of the sidewall structures. A slider is disposed in the lead screw, and the slider is connected to the other sidewall structure. By rotating the lead screw, the distance between the slider and the end of the lead screw is adjusted, thereby adjusting the distance between the two sidewall structures. A handwheel 430 can be connected to the lead screw, and the lead screw can be rotated by rotating the handwheel 430.

[0068] Optionally, when the conveyor 410 is in the form of a conveyor belt, the conveyor belt can extend along the conveying direction of the spring string 2000, serving to guide and limit the spring string 2000 during the laying process. In this way, the conveyor 410 can both provide power for the movement of the spring string 2000 and guide it. Of course, in other examples, a guide structure 420 can be additionally provided in the feeding assembly 400 to achieve the guiding effect on the spring string 2000.

[0069] In some embodiments, the feeding assembly 400 further includes a guide structure 420, which is disposed on the feeding side of the conveyor 410. The guide structure 420 includes a first guide component 421, which is disposed radially along the spring on both sides of the spring string 2000. The space between the two sets of first guide components 421 forms a feeding channel 401. The first guide structure 420 can guide the spring in the circumferential direction, ensuring that the spring string 2000 can be smoothly laid on the welding station 112, avoiding twisting of the spring string 2000, and improving the stability and reliability of feeding. Exemplarily, the first guide component 421 can be an array of rollers (such as... Figure 5 (As shown), conveyor belt, drive chain, baffles, etc.

[0070] In some embodiments, the guide structure 420 includes a second guide component 422, which is disposed radially on the end face of the spring string 2000. The side of the second guide component 422 facing the spring string 2000 forms part of the feeding channel 401. By utilizing the guide structure 420 disposed on the end face of the spring, the spring can be axially limited, preventing problems such as spring bounce in the spring string 2000 and improving the reliability of feeding. Similarly, the second guide component 422 can be an array of rollers (such as...). Figure 5 (As shown), conveyor belt, drive chain, baffles, etc.

[0071] For example, one or more second guide components 422 may be provided. When one second guide component 422 is provided, the second guide component 422 is horizontally arranged, forming two layers of feeding channels 401 on both sides along the first direction. The second guide component constitutes the bottom wall of the upper feeding channel 401 and the top wall of the lower feeding channel 401. Of course, a second second guide component 422 may also be provided on the top surface of the upper feeding channel 401, or a third second guide component 422 may be provided on the bottom surface of the lower feeding channel 401, thereby providing a more stable guiding effect on the spring string 2000.

[0072] It is understandable that the first guide component 421 and the second guide component 422 can be set individually, or the first guide component 421 and the second guide component 422 can be set simultaneously, without limitation here.

[0073] In some embodiments, to further arrange the spring strings 2000 more orderly before entering the feeding assembly 400, a spring tidying structure (not shown) can be provided upstream of the feeding assembly 400 along the conveying direction of the spring strings 2000. The spring tidying structure can tidy up multiple spring strings 2000, preventing them from tangling together before entering the feeding assembly 400. Exemplarily, the spring tidying structure can be a smooth-surfaced baffle or roller. The spring strings 2000 are wound around the outer circumference of the baffle (or roller). Utilizing the guiding effect of the baffle, the spring strings 2000 can be guided from different directions into the feeding assembly 400, solving the problem of the spring strings 2000 tangling together. Alternatively, in another example, the spring arrangement structure can also be configured as a guide structure with multiple platforms spaced apart along the first direction. Each platform corresponds to a different multi-level feeding channel 401. In this way, multiple spring strings 2000 can be separated before entering the feeding assembly 400, thereby preventing the spring strings 2000 from tangling with each other and improving the orderliness and reliability of the spring string 2000 feeding process.

[0074] In some embodiments, the welding knife assembly 110 is movable along a third direction. The welding knife assembly 110 can also be inserted into or withdrawn from between adjacent springs of the spring string 2000 along a first direction. When the welding knife assembly 110 is withdrawn from between the springs and moves along a third direction to the side of the spring string 2000 facing the welding head mechanism 2000, the welding knife assembly 110 can push the spring string 2000 towards the forming channel 301 along the third direction. After one of the welding knife assemblies 110 completes welding, its welding knife 111 is withdrawn from the gap between the spring strings 2000 and moves along a third direction to the outside of the spring string 2000 (i.e., the side of the spring string 2000 facing the welding head mechanism 2000). Thus, driving the welding knife assembly 110 to move along a third direction towards the forming channel 301 can push the spring string 2000 away from the welding station 112. After the feeding assembly 400 lays the next row of spring strings 2000 in the welding station 112, the spring strings 2000 cover the welding knife assembly 110 again. Then the welding head assembly 210 approaches and connects with another set of welding knife assemblies 110. The welding of the spring strings 2000 is achieved by the mutual connection between the welding head assembly 210 and its welding knife 111.

[0075] In some embodiments, please refer to Figure 9 The welding knife assembly 110 includes a first mounting base 113 and welding knives 111. One end of each welding knife 111 is rotatably connected to the first mounting base 113. When the welding knife 111 engages with the welding head assembly 210, the welding knife 111 can rotate relative to the first mounting base 113 so that the welding knife 111 abuts against the limiting component. Correspondingly, the welding head 211 is also mounted via an elastic connector to swing slightly about a rotation axis with the axial direction as the second direction. When the welding head 211 approaches the welding knife 111, the welding head 211 can press the welding knife 111 towards the first mounting base 113, improving the contact between the welding head 211 and the welding knife 111, so that the welding head 211 can make complete contact with the welding knife 111, thereby improving the welding quality of the weld.

[0076] Optionally, the first mounting bases 113 of the two sets of welding knife assemblies 110 are respectively mounted on both ends of the welding knife 111 along a first direction, such as... Figure 9 As shown in (a), or, the first mounting bases 113 of both sets of welding knife assemblies 110 are disposed at the same end of the welding knife 111 along the first direction, as shown in (a). Figure 9 As shown in (b).

[0077] Optionally, when the welding knife 111 is squeezed by the welding head 211, the back of the welding knife 111 can abut against the limiting component 300 (e.g., the first receiving member 310 or a receiving member). This allows the limiting component 300 to limit the rotation range of the welding knife 111 and provide support for the welding knife 111, thereby improving the stability when the welding knife 111 and the welding head 211 are connected.

[0078] In some embodiments, the welded spring string 200 can be pushed to the forming channel 301 without relying on the welding knife assembly 110, but instead pushed by the push rod assembly 500. For details, please refer to... Figure 8 The bed frame assembly 1000 also includes at least one set of push rod assemblies 500, each comprising a plurality of push rods 510 extending along a first direction. The spacing between the push rods 510 is the same as the spacing between the welding blades 111 of the welding blade assembly 110. The push rods 510 are movable along the first direction and a third direction to push the spring string 2000 from the welding station 112 toward the forming channel 301. Alternatively, the spacing between the push rods 510 may be twice the spacing between the welding blades 111 of the welding blade assembly 110. In this case, the push rods need to move along a second direction, pushing the spring string in two stages. Using the pushing action of the push rod assembly 500, the spring string 2000 can be pushed from the welding station 112 to the forming channel 301, thereby freeing up the welding station 112 to avoid occupying space, so as to lay the next row of spring strings 2000. The spring strings 2000 that have been welded can enter the forming channel 301 for temporary storage. After the entire bed net 3000 is welded, the bed net 3000 can be transferred away from the forming channel 301.

[0079] In some embodiments, the push rod assemblies 500 are configured as two sets, with the push rods 510 of the two sets of push rod assemblies 500 arranged alternately along a second direction. The positions of the two sets of push rods 510 correspond to the two sets of welding knife assemblies 110, respectively. After one set of welding knife assemblies 110 is pulled out from between the spring strings 2000 along a first direction, the push rod assembly 500 in the corresponding position pushes the spring string 2000 towards the forming channel 301 through the movement in the first direction and the third direction, so that when the welding knife assembly 110 is reset, it can switch to the side of the spring string 2000 closer to the welding station 112. By setting two sets of push rod assemblies 500, it is possible to satisfy the requirement that each set of welding knife assemblies 110 is correspondingly set. By controlling the alternating movement of the two sets of push rod assemblies 500, it is possible to ensure that each set of push rod assemblies 500 moves independently without interfering with each other, thereby improving the reliability of the movement of the push rod assembly 500.

[0080] In some embodiments, the pusher assembly 500 is configured as a set, and the pusher assembly 500 is movable in a second direction to cut corresponding to two sets of welding knife assemblies 110. After one set of welding knife assemblies 110 is pulled out from between the spring strings 2000 in a first direction, the pusher assembly 500 moves in the second direction to the corresponding position and pushes the spring strings 2000 toward the forming channel 301 through the movement in the first and third directions, so that when the welding knife assembly 110 is reset, it can switch to the side of the spring strings 2000 closer to the welding station 112. By utilizing the second direction movement of the pusher assembly 500, it is possible to satisfy the corresponding setting with one of the two sets of welding knife assemblies 110 respectively, thereby realizing the pushing of the spring strings 2000 toward the forming channel 301.

[0081] In some embodiments, the push rod assembly 500 is disposed on the welding head mechanism 200, and the push rod 510 is spaced apart from the welding head assembly 210 along a second direction and moves with the welding head assembly 210. In this way, the push rod assembly 500 can move simultaneously with the movement of the welding head assembly 210, thereby reducing the number of power structures and simplifying the structural configuration of the bed mesh assembly device 1000.

[0082] In some embodiments, the push rod assembly 500 further includes a connecting rod 520 and a first driving member 530. Multiple push rods 510 extend along a first direction and are all connected to the connecting rod 520. The first driving member 530 drives the push rods 510 to move along a third direction, thereby causing the push rods 510 to push the spring string 2000 along the third direction. By using the first driving member 530 to drive the connecting rod 520, and then using the connecting rod 520 to simultaneously drive multiple push rods 510 to push the spring string 2000, the number of driving members can be reduced, achieving the effect of one power source driving multiple push rods 510, thus simplifying the structure of the push rod assembly 500. For example, the first driving member 530 can be a motor, cylinder, or other structure.

[0083] When welding large-sized bed wire mesh 3000s, the number of welding head assemblies 210 may be less than the number of welding knife assemblies 110. In this case, a single connection between the welding head assembly 210 and the welding knife assembly 110 is insufficient to weld all positions of the spring string 2000. Therefore, welding can be completed in multiple stages by moving the welding head assembly 210 along the second direction. Specifically, in some embodiments, the welding head assembly 210 is movable along the second direction to connect with welding knives 111 at different positions in the same welding knife mechanism 100, thereby completing welding at different positions. In this way, the welding head assembly 210 is connected to the welding knives 111 at different positions in two or more stages, thereby achieving multiple welding in the second direction to complete the welding of a whole row of spring strings 2000.

[0084] Optionally, the bed mesh assembly 1000 further includes a second mounting base 630 and a fourth driving member 640. The second mounting base 630 extends along a second direction, and multiple welding head assemblies 210 are spaced apart on the second mounting base 630 along the second direction. The fourth driving member 640 can drive the second mounting base 630 to move along the second direction, thereby enabling the welding head assemblies 210 to be correspondingly connected to welding blades 111 at different positions. A push rod assembly 500 can also be mounted on the second mounting base 630, allowing the push rod assembly 500 to move along with the welding head assembly 210 in the second direction. Of course, in other examples, the push rod assembly 500 and the welding head mechanism 200 can also be set independently, i.e., different driving members can be used to independently drive the push rod assembly 500 and the welding head mechanism 200.

[0085] In some embodiments, the bed mesh assembly 1000 further includes a first track 610 and a second drive member 620. The first track 610 extends along a first direction, and the welding head mechanism 200 is movably connected to the first track 610. The second drive member 620 can drive the welding head mechanism 200 to move along the first track 610. The welding head mechanism 200 can move in the first direction to avoid the feeding assembly 400. By using the movement of the welding head mechanism 200 in the first direction to avoid the feeding assembly 400, interference between the welding head mechanism 200 and the feeding assembly 400 can be avoided during the feeding process, improving the reliability of the feeding process. At the same time, by achieving misalignment and avoidance between the welding head mechanism 200 and the feeding assembly in the first direction, the compactness of the bed mesh assembly 1000 structure is improved.

[0086] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
