Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mattress automation production, and particularly relates to a bed net combination device. BACKGROUND

[0002] The main component of a spring mattress is a spring bed net, and the manufacturing method of the spring bed net is usually to sequentially connect multiple springs to form a pocketed spring string, and then sequentially weld the spring string side by side. For example, the connecting cloth between the two adjacent springs in the spring string is used as a welding position, and the combination of a welding knife and a welding head can weld the cloth at the welding positions of the two adjacent rows of spring strings to each other, so as to connect and fix the two rows of spring strings.

[0003] Generally, the welding positions between the two adjacent rows of spring strings are arranged alternately. When welding, the first row of spring strings is laid first, and the first welding position of the spring string is welded; then the second row of spring strings is laid, and the second welding position of the spring string is welded, and the first welding position and the second welding position are arranged alternately, which can realize the welding forming of the spring bed net. However, in the process of laying the spring string, the welding head needs to be separated from the welding knife, and after the spring string is laid in place, the welding head and the welding knife can be connected again. In this process, due to the waiting time of the welding head, the welding head is in an idle state during the waiting time, which causes time waste and is not conducive to improving the welding speed and the production efficiency of the bed net. CONTENT OF THE UTILITY MODEL

[0004] To solve at least one of the above technical problems, the present application provides a bed net combination device which can save the waiting time of the welding head, improve the welding efficiency, and adopts the technical scheme as follows.

[0005] The bed net combination device provided in the first aspect of the present application comprises a welding head mechanism, a feeding assembly, and a plurality of sets of welding knife mechanisms arranged along a first direction. One side of each set of the welding knife mechanisms forms a welding station. The welding knife mechanism comprises two groups of welding knife assemblies, each of which comprises a plurality of welding knives arranged along the first direction. The welding knives in the same group are arranged alternately along a second direction, and the welding knives in different groups are arranged alternately along the second direction to correspond to the positions between the adjacent springs of the spring string. The two groups of welding knife assemblies are alternately extracted from between the two adjacent rows of spring strings and moved to one side of the spring string close to the welding station. The welding head mechanism is movable to any welding station along the first direction. The welding head mechanism comprises a plurality of welding head assemblies arranged alternately along the second direction. The welding head assemblies can cooperate with any group of welding knife assemblies to complete welding. The feeding assembly is used to move along the second direction to transport the spring string to the welding station. When the welding head mechanism moves to any welding station, the feeding assembly transports the spring string to the remaining welding stations.

[0006] In some embodiments of this application, two sets of feeding components and two sets of welding knife mechanisms are provided, with the feeding components and welding knife mechanisms being provided in a one-to-one correspondence.

[0007] In some embodiments of this application, the feeding assembly includes conveyors arranged in pairs along a second or third direction at intervals, forming at least a partial 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.

[0008] In some embodiments of this application, the distance between the pairs of conveyors can be adjusted to accommodate spring strings of different diameters.

[0009] 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 includes a first guide component, which is disposed radially along the spring on both sides of the spring string. The space between two sets of the first guide components forms the feeding channel; and / or

[0010] The guiding structure includes a second guiding component, which is disposed radially on the end face of the spring string, and the side of the second guiding component facing the spring string forms part of the feeding channel.

[0011] In some embodiments of this application, the welding knife assembly is movable along a third direction. When the welding knife assembly is pulled out from between the spring strings along a first direction and moved along a third direction to the side of the spring strings facing the welding head mechanism, the welding knife assembly can push the spring strings away from the welding head mechanism along the third direction.

[0012] In some embodiments of this application, the bed mesh assembly device further includes multiple sets of limiting components. The limiting components are disposed along a third direction on the side of the welding knife mechanism opposite to the welding station. The limiting components are disposed one-to-one with the welding knife mechanism. The surface of the limiting components is formed into a forming channel for the welded bed mesh to pass through.

[0013] In some embodiments of this application, the limiting component includes a first receiving member and a second receiving member spaced apart along a first direction, with the first receiving member and the second receiving member forming the forming channel. Both the first receiving member and the second receiving member extend along a second direction, and the distance between the second receiving member and the second receiving member is adjustable. When the welding head mechanism applies pressure to the welding knife assembly, the welding knife assembly can abut against the first receiving member and the second receiving member.

[0014] 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 first receiving member and the second receiving member facing the welding head mechanism. The support members are disposed in the gap between adjacent welding blades and extend along a third direction into the welding station. The support members are used to place the spring string laid by the feeding component.

[0015] In some embodiments of this application, the first receiving member and the second receiving member are both limiting plates, the support member is snapped onto the limiting plate, and the spacing of the plurality of support members along the second direction is adjustable.

[0016] In some embodiments of this application, the welding knife assembly includes a first mounting base and a welding knife. One end of the welding knife is rotatably connected to the first mounting base. When the welding knife engages with the welding head assembly, the welding knife can rotate relative to the first mounting base, and the back of the welding knife abuts against a limiting plate to make the welding knife fit against the welding head assembly.

[0017] In some embodiments of this application, the welding head assembly is movable along a second direction so that the welding head assembly can cooperate with the welding knife at different positions in the same welding knife mechanism to complete welding at different positions.

[0018] Secondly, this application provides a method for assembling a bed net, including...

[0019] The welding head mechanism works in conjunction with the first welding knife mechanism to complete the welding; at the same time, the feeding assembly lays spring strings at the welding station of the second welding knife mechanism.

[0020] The welding head mechanism switches from the first welding knife mechanism to the welding station of the second welding knife mechanism;

[0021] The welding head mechanism works in conjunction with the second welding knife mechanism to complete the welding; at the same time, the feeding assembly lays a string of springs at the welding station of the first welding knife mechanism.

[0022] The welding head mechanism switches from the second welding knife mechanism to the welding station of the first welding knife mechanism.

[0023] In some embodiments of this application, the welding head mechanism cooperates with the first welding knife mechanism to complete welding, including: the welding head mechanism cooperating with one set of welding knife assemblies of the first welding knife mechanism for welding; and the welding head mechanism cooperating with another set of welding knife assemblies of the first welding knife mechanism for welding.

[0024] The welding head mechanism cooperates with the second welding knife mechanism to complete the welding, including: the welding head mechanism and one set of welding knife assemblies of the second welding knife mechanism cooperate to weld; the welding head mechanism and another set of welding knife assemblies of the second welding mechanism cooperate to weld.

[0025] In some embodiments of this application, when the number of welding heads in the welding head mechanism is less than the number of welding blades in the welding blade assembly, the welding head mechanism cooperates with the welding blade assembly to complete the welding, including:

[0026] The welding head mechanism cooperates with a portion of the welding knife assembly to achieve welding;

[0027] The welding head mechanism moves along the second direction, and the welding head mechanism cooperates with the remaining welding blades of the welding blade assembly to achieve welding;

[0028] Repeat the previous step until welding is completed with all welding blades.

[0029] The embodiments of this application have at least the following beneficial effects: By utilizing the alternating operation of the feeding assembly and the welding head mechanism, when the welding head mechanism is engaged in welding with the first set of welding knife mechanisms, the feeding assembly delivers spring strings to other welding stations. When the welding head mechanism completes welding, it separates from the first set of welding knife mechanisms and switches to the second set of welding knife mechanisms in a first direction for welding. During the welding time with the second set of welding knife mechanisms, the feeding assembly lays spring strings for the first set of welding knife mechanisms. After welding with the second set of welding knife mechanisms is completed, the welding head mechanism switches to engage with the first set of welding knife mechanisms and can immediately begin welding without waiting for feeding, thus saving and shortening the waiting time of the welding head mechanism during the laying of spring strings, helping to reduce wasted time, thereby increasing welding speed and improving the efficiency of the bed mesh assembly.

[0053] Please see Figures 1 to 6 The first aspect of this application provides a bed mesh assembly device 1000, including a feeding assembly 400, a welding head mechanism 200, and multiple sets of welding knife mechanisms 100. Multiple sets are arranged along a first direction (e.g., ...). Figure 1The welding knife mechanisms 100 are distributed in the z-direction shown. Each welding knife mechanism 100 has a welding station 101 formed on one side. The welding knife mechanism 100 includes two sets of welding knife assemblies 110. Each welding knife assembly 110 includes multiple welding knives 111 extending along a first direction. The welding knives 111 in the same set extend along a second direction (e.g., ...). Figure 1 The welding blades 111 are arranged at intervals in the x-direction shown. Different groups of welding blades 111 are alternately arranged along the second direction to correspond to the positions between adjacent springs of the spring string 2000. Two groups of welding blade assemblies 110 are alternately pulled out from between two adjacent rows of spring strings 2000 and moved to the side of the spring string 2000 near the welding station 101. The welding head mechanism 200 is movable to any welding station 101 along the first direction. The welding head mechanism 200 includes a plurality of welding head assemblies 210 spaced apart along the second direction. The welding head assembly 210 can cooperate with any group of welding blade assemblies 110 to complete the welding. The feeding assembly 400 is used to move along the second direction to transport the spring string 2000 to the welding station 101. When the welding head mechanism 200 moves to any welding station 101, the feeding assembly 400 transports the spring string 2000 to the other welding stations 101.

[0054] In this application, the feeding assembly 400 and the welding head mechanism 200 work alternately. When the welding head mechanism 200 and the welding knife mechanism 100 of any welding station 101 (with...) are engaged in the alternating operation of the feeding assembly 400 and the welding head mechanism 200, the welding head mechanism 200 and the welding knife mechanism 100 of any welding station 101 are engaged in the alternating operation of the welding head mechanism 200 and the welding knife mechanism Figure 1 For example, when the first welding knife mechanism (hereinafter referred to as the first welding knife mechanism) is engaged in welding, the feeding assembly 400 feeds spring strings 2000 to other welding stations 101. When the welding head mechanism 200 completes welding, it separates from the first welding knife mechanism and switches to another welding knife mechanism 100 (hereinafter referred to as the second welding knife mechanism) in the first direction for welding. During the welding time with the second welding knife mechanism, the feeding assembly 400 lays the spring strings 2000 on the first welding knife mechanism. After welding with the second welding knife mechanism is completed, the welding head mechanism 200 switches to engage with the first welding knife mechanism and can immediately perform welding without waiting for feeding, thereby saving and shortening the waiting time of the welding head mechanism 200 during the laying of the spring strings 2000, helping to reduce time waste, thereby increasing welding speed and improving the efficiency of the bed mesh 3000 assembly.

[0055] by Figure 1 For example, the first direction is the vertical direction, and the first, second, and third directions are perpendicular to each other.

[0056] Of course, in other instances, the first direction can also be the horizontal direction, and the third direction can be the vertical direction, such as... Figure 2 As shown. In Figure 2 In the example, the bed mesh 3000 is welded and assembled along the vertical direction. Specifically, multiple sets of welding knife mechanisms 100 are welded along a first direction (e.g., Figure 2The welding head mechanism 200 is arranged in a z-direction (as shown), and is positioned along a third direction (e.g., the z-direction). Figure 2 (As shown in the y-direction) approaching or moving away from the welding knife assembly 110. That is, the welding knife assembly 110 is horizontally positioned below the welding head mechanism 200, and the welding station 101 is vertically upward. At this time, when the welding knife assembly 110 is pulled out from between the spring strings 2000 in the horizontal direction, the spring strings 2000 can move downward by their own weight, or by being pressed down by a set of separately provided pressure plates or spaced pressure rods. Then the welding knife assembly 110 returns in the horizontal direction to the side of the spring strings 2000 closer to the welding station 101. In this way, the welding knife assembly 110 only needs to reciprocate in the horizontal direction.

[0057] If the welding knife assembly 110 adopts the following... Figure 1 In the layout shown, the welding knife assembly 110 is vertically arranged. After the welding knife assembly 110 is pulled out from the spring string 2000 along the first direction, it can be pushed by a set of separately provided pressure plates or spaced pressure rods to push the spring string 2000 away from the welding station 101. Then the welding knife assembly 1100 returns to the side of the spring string 2000 near the welding station 101 along the first direction. In this way, the welding knife assembly 110 only needs to reciprocate along the first direction.

[0058] The two examples above illustrate two different layout methods for the first, second, and third directions. This application does not specifically limit the layout methods for these three directions. The following will use... Figure 1 Let's continue with the explanation using the component form as an example.

[0059] 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 7 The welding of one of the 3000 mesh mattresses will be used as an example for explanation. Figure 7 In the diagram, each welding position in each row of 2000 spring strings is identified by indicator lines with numerical numbers, and... Figure 7 The laying sequence of each spring string 2000 in the bed net 3000 is also indicated by arrow-shaped guide lines. For example... Figure 7 As 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.

[0060] 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 101. 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 top of the even-numbered rows of spring strings 2000. The welding head assembly 210 presses against the welding station 101. The welding head assembly 210 and the second welding blade 1112 clamp and weld the two rows of spring strings 2000 together at the second welding position 920. 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.

[0061] For example, the welding head assembly 210 includes a welding head 211 and a welding head drive 212. The welding head drive 212 drives the welding head 211 to extend and connect with the welding knife 111 to achieve welding. The welding head drive 212 also drives the welding head 211 to retract and separate from the welding knife 111. The welding head 211 can be an ultrasonic welding head 211, a thermal welding head 211, etc.

[0062] Optionally, with Figure 1 For example, the bed mesh assembly equipment 1000 is equipped with two sets of welding knife mechanisms 100, which are distributed along the first direction. Of course, in other examples, three, four or more sets of welding knife mechanisms 100 can be set along the first direction, which is not limited here. The following explanation will continue with the example of two sets of welding knife mechanisms 100.

[0063] In some embodiments, two sets of feeding components 400 and two sets of welding knife mechanisms 100 are provided, with each feeding component 400 corresponding to a welding knife mechanism 100. This allows the two sets of feeding components 400 to independently feed the welding stations 101 on each welding knife mechanism 100, without needing to move the feeding components 400 along the first direction, thus meeting the feeding needs of both welding knife mechanisms 100 and further improving the laying efficiency of the spring string 2000. During this process, since the welding operation and feeding operation in the welding station 101 are always alternated, when welding, the feeding mechanism is positioned at one end of the welding knife assembly 110 along the second direction, avoiding interference with the welding head mechanism 200.

[0064] As an alternative implementation, the feeding assembly 400 can also be set up in one set. After the spring string 2000 is laid on one set of welding knife mechanism 100, the feeding assembly 400 can switch to the position of another set of welding knife mechanism 100 in the first direction to feed the material.

[0065] In some embodiments, the feeding assembly 400 includes conveyors 410, which are paired along a second direction or a third direction (e.g., Figure 5 Arranged at intervals (in the y-direction shown), the paired conveyor elements 410 form at least a partial feeding channel 401. At least one conveyor element 410 is a driving element, which includes at least one of a dial wheel, a roller, and a conveyor belt. The driving element moves to transport the spring string 2000. The movement of the spring string 2000 is powered by the rotation of the driving element and the friction between the surface of the driving element and the surface of the spring string 2000, thereby realizing the laying action of the spring string 2000. The driving element can be in the form of a dial wheel (e.g., ...). Figure 5 (As shown in the example), the grooves formed between adjacent pawls of the dial wheel can engage with the outer circumference of the spring, and the rotation of the dial wheel conveys the spring string 2000. Of course, rollers or conveyor belts can also be used. In the paired conveyor components 410, both can be designated as driving components, meaning both conveyor components 410 are powered. Alternatively, in other examples, one conveyor component 410 can be designated as the driving component and the other as the driven component; no specific limitation is made here.

[0066] In some embodiments, the distance between the paired conveyors 410 is adjustable to accommodate spring strings 2000 of different diameters. By adjusting the distance between the paired conveyors 410 for spring strings 2000 of different diameters, the combination requirements of different sizes of bed nets can be met, improving the versatility of the feeding assembly 400. Optionally, the distance between the paired conveyors 410 can be adjusted manually or electrically; this is not limited here.

[0067] 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.

[0068] 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 101, avoiding twisting of the spring string 2000, and improving the stability and reliability of feeding. Exemplarily, the first guide component 421 can be an arranged roller or wheel (such as...). Figure 5 (as shown), conveyor belts, drive chains, etc.

[0069] 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 bouncing 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 belts, drive chains, etc.

[0070] 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.

[0071] In some embodiments, the welding knife assembly 110 is movable along a third direction. When the welding knife assembly 110 is pulled out from between the spring strings 2000 along a first direction and moves along a third direction to the side of the spring strings 2000 facing the welding head mechanism 2000, the welding knife assembly 110 can push the spring strings 2000 away from the welding head mechanism 2000 along the third direction. By using the pushing action of the welding knife 111, the spring strings 2000 can be pushed out of the welding station 101 and leave the welding station 101, thereby freeing up the welding station 101 to avoid occupying space, so as to facilitate the laying of the next row of spring strings 2000. The spring strings 2000 that have been welded can enter the forming channel 301 for waiting and temporary storage. After the entire bed net 3000 is welded, the bed net 3000 can be transferred away from the forming channel 301. By using the welding knife assembly 110 to move along a third direction, the spring string 2000 can be pushed toward the forming channel 301 by the first direction and the third direction movement of the welding knife assembly 110 itself, and the welding knife assembly 110 can be switched to the side of the spring string 2000 closer to the welding station 101. In this process, there is no need to set up additional pressure rods or pressure plates to push the spring string 2000, which helps to simplify the structure of the bed net combination equipment 1000.

[0072] In some embodiments, the bed net assembly device 1000 further includes multiple sets of limiting components 300. The limiting components 300 are disposed along a third direction on the side of the welding knife mechanism 100 opposite to the welding station 101. Each limiting component 300 corresponds to one of the welding knife mechanisms 100. The surface of each limiting component 300 is formed into a forming channel 301 for the passage of the welded bed net 3000. The forming channel 301, constructed using the limiting components 300, can hold welded spring strings 2000. After a certain number of multiple rows of spring strings 2000 are welded, a bed net 3000 is formed and can be output from the forming channel 301. By setting multiple sets of limiting components 300 and corresponding them one-to-one with the welding knife mechanism 100, multiple bed nets 3000 can be held simultaneously. The forming channel 301 can define a relatively independent placement space for each bed net 3000, preventing mutual interference between multiple bed nets 3000 during the welding process.

[0073] In some embodiments, the limiting component 300 includes a first receiving member 310 and a second receiving member 320 spaced apart along a first direction, forming a forming channel 301 between the first receiving member 310 and the second receiving member 320. Both the first receiving member 310 and the second receiving member 320 extend along a second direction, and the distance between the second receiving member 320 and the second receiving member 320 is adjustable. When the welding head mechanism 200 applies pressure to the welding knife assembly 110, the welding knife assembly 110 can abut against the first receiving member 310 and the second receiving member 320. By defining the forming channel 301 between the first receiving member 310, the second receiving member 320 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 distance between the first receiving member 310 and the second receiving member 320 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. When the welding head 211 and the welding knife 111 cooperate and apply pressure, the limiting component 300 can provide support force to the back of the welding knife 111. That is, by using the limiting component 300 to abut against the back of the welding knife assembly 110, the welding knife 111 can be more stable when the welding head 211 squeezes the welding knife 111, thereby increasing the bonding force between the welding head 211 and the welding knife 111, which helps the welding head 211 and the welding knife 111 to form a good fit and improve the welding effect.

[0074] For example, the first receiving member 310 may include at least one of a platform, a baffle, a partition, and a conveyor belt. Figure 5 In one embodiment, the first receiving member 310 is configured as a baffle (limiting plate).

[0075] 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 first receiving member 310 and the second receiving member 320 facing the welding head mechanism 200. The support members 340 are disposed in the gap between adjacent welding blades 111 and extend along a third direction into the welding station 101. The support members 340 are used to place the spring string 2000 laid by the feeding component 400. By extending the support members 340 into the welding station 101, the spring string 2000 laid on the welding station 101 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 101 can be fully utilized, making the arrangement of the support members 340 and the welding blades 111 more compact.

[0076] In some embodiments, the first receiving member 310 and the second receiving member 320 are both limiting plates, and the support member 340 is snapped onto 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 support the position of each spring, thereby improving the stability of the support and the adaptability to spring strings 2000 of different specifications.

[0077] In some embodiments, the welding knife assembly 110 includes a first mounting base 113 and a welding knife 111. One end of the 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 back of the welding knife 111 abuts against the limiting plate. 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 fit between the welding head 211 and the welding knife 111, so that the welding head 211 can fully contact the welding knife 111, thereby improving the welding quality of the weld.

[0078] 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 steps 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, allowing it to engage with welding knives 111 at different positions within the same welding knife mechanism 100 to complete 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 steps, thereby achieving multiple welding in the second direction to weld a complete row of spring strings 2000.

[0079] Secondly, please refer to Figure 8 This application provides a method for assembling a bed net, which can be implemented using the bed net assembly device 1000 provided in the first aspect. The bed net assembly method specifically includes...

[0080] S100. The welding head mechanism 200 cooperates with the first welding knife mechanism to complete the welding; at the same time, the feeding assembly 400 lays the spring string 2000 on the welding station 101 of the second welding knife mechanism.

[0081] S200. Welding station 101 where the welding head mechanism 200 switches from the first welding knife mechanism to the second welding knife mechanism;

[0082] S300. The welding head mechanism 200 cooperates with the second welding knife mechanism to complete the welding; at the same time, the feeding assembly 400 lays the spring string 2000 on the welding station 101 of the first welding knife mechanism.

[0083] S400. Welding head mechanism 200 switches from the second welding knife mechanism to the welding station 101 of the first welding knife mechanism.

[0084] During the welding process between the welding head mechanism 200 and the first welding knife mechanism, the feeding assembly 400 simultaneously lays spring strings 2000 on the second welding knife mechanism. This fully utilizes the idle time of the welding station 101 of the second welding knife mechanism. When the welding head mechanism 200 completes welding and switches to the welding station 101 of the second welding knife mechanism, it can immediately cooperate with the second welding knife mechanism for welding without waiting for the spring strings 2000 to be laid, thus saving waiting time and improving welding efficiency. Similarly, when the welding head mechanism 200 is cooperating with the second welding knife mechanism for welding, the feeding assembly 400 lays spring strings 2000 on the first welding knife mechanism. This alternating cycle ensures that the welding head mechanism 200 and the feeding assembly 400 are always in working condition, thereby reducing waiting time and improving the welding efficiency of the bed mesh 3000.

[0085] In some embodiments, step S100, where the welding head mechanism 200 cooperates with the first welding knife mechanism to complete welding, includes:

[0086] S101. The welding head mechanism 200 cooperates with one of the welding knife assemblies 110 of the first welding knife mechanism for welding;

[0087] S102. The welding head mechanism 200 cooperates with another set of welding knife assemblies 110 of the first welding knife mechanism for welding.

[0088] The above step S300, where the welding head mechanism 200 cooperates with the second welding knife mechanism to complete the welding, includes:

[0089] S301. The welding head mechanism 200 cooperates with one of the welding knife assemblies 110 of the second welding knife mechanism for welding;

[0090] S302. The welding head mechanism 200 cooperates with another set of welding knife assemblies 110 of the second welding mechanism for welding.

[0091] By alternately connecting the welding head mechanism 200 with two different welding knife assemblies 110 in the same welding knife mechanism 100, welding at different welding positions on the spring string 2000 can be achieved, thereby realizing the welding and forming of the spring bed mesh 3000.

[0092] In some embodiments, when the number of welding heads 211 in the welding head mechanism 200 is less than the number of welding blades 111 in the welding blade assembly 110, the welding head mechanism 200 cooperates with the welding blade assembly 110 to complete the welding, including:

[0093] S101. The welding head mechanism 200 cooperates with a portion of the welding knife assembly 110, the welding knife 111, to achieve welding;

[0094] S102. The welding head mechanism 200 moves along the second direction, and the welding head mechanism 200 cooperates with the remaining welding blades 111 of the welding blade assembly 110 to achieve welding;

[0095] S103. Repeat the previous step until welding is completed with all welding blades 111.

[0096] In this way, the welding head assembly 210 is connected to the welding blades 111 at different positions in two or more steps, thereby achieving multiple welding in the second direction to weld a whole row of spring strings 2000. Optionally, the bed mesh assembly device 1000 also includes a first track 610 and a second drive member 620. The first track 610 extends along the first direction, the welding head mechanism 200 is movably connected to the first track 610, and the second drive member 620 can drive the welding head mechanism 200 to move along the first track 610, thereby achieving welding with the welding blades 111 at different positions.

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 described in the embodiments of this application can be combined with each other.
