[0025] The following specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.

[0026] Embodiment 1, as Figure 1-7As shown, a mattress punching cutter head includes a mounting post a2 which is used to be assembled with a motor shaft a10 of a punching rotary motor a1 and extends in the up-down direction. The motor shaft a10 of the punching rotary motor a1 also extends in the up-down direction. The mounting post a2 can be connected to the motor shaft a10 by a pin. The cutter head is preferably made of carbon steel, and of course, metal materials such as steel can also be used. A blade a3 which rotates with the mounting post a2 is fixed at the bottom of the mounting post a2. The mounting post a2 preferably has a cylindrical main body, and the lateral width of the blade a3 is preferably larger than 100 mm. The diameter of the mounting column a2 is preferably greater than that of the mounting column a2, and the axis of the mounting column a2 preferably passes through the center position of the width direction of the blade a3. The blade a3 includes a main body support cutting portion a41 in an upright shape, and a pre-drilling drill bit a42 which can drill into the flexible pad before the main body support cutting portion a41 is integrally connected to the bottom of the main body support cutting portion a41. The size of the pre-drilling drill bit a42 is smaller than that of the main body support cutting portion a41. The main function of the pre-drilling drill bit a42 is to first penetrate into the flexible pad and rotate to tear a small hole, and then continue to tear downward by itself. Flexible pad, at the same time, the main body supporting cutting part a41 acts on the flexible pad to cut a large flexible pad hole for the magnetic particles to be placed. Of course, the drilling rotating motor a1 can be connected through a lifting motor or a lifting cylinder to enable it to be lifted up and down, because in the drilling process, while the mounting column a2 motor shaft a10 drives the rotation, it is also necessary to lower the drilling hole to form a flexible pad hole for the magnetic particles to be placed on the flexible pad. This way of descending and rotating the cutter head allows the opening to be opened into a blind hole, or a non-connected hole. The advantage of this is that it can greatly improve the efficiency in the mattress production process. Like traditional punching and opening through-hole equipment, it is necessary to open holes in the flexible pad separately, and the flexible pad cannot be installed on the base structure before opening holes. Therefore, the flexible pad must be opened in advance and then collected, and then installed on the base structure, which will waste more time and reduce efficiency. The cutter head of this embodiment can open a blind hole, so that after the flexible pad is installed on the base structure, it can directly open a hole and enter the next process during the transportation process on the conveyor line, reducing the intermediate collection waiting time, which can greatly improve efficiency. The mounting column a2 and the blade a3 can be formed by integrally connecting the same material, which has a better effect and can be realized through existing forging, casting and other processes.

[0027] Preferably, the top of the main body supporting cutting portion a41 is integrally connected to the bottom of the mounting post a2, that is, the implementation structure of the above-mentioned connection between the mounting post a2 and the blade a3.

[0028] Specifically, the main body supporting cutting part a41 includes a main cutting plate a411 in an upright plate shape, the main cutting plate a411 is flat, and the cross section is preferably rectangular, that is, the four corners are right-angled cutting edges. The top of the pre-drilling drill a42 is integrally connected with the bottom of the main cutting plate a411, and the pre-drilling drill a42 is an upright plate-like structure. The pre-drilling drill a42 is preferably at the bottom center of the main cutting plate a411. The width of the pre-drilling drill a42 is preferably controlled at 1-2 mm, and try not to exceed 4 mm. The width of the main cutting plate a411 is preferably about ten times the width of the pre-drilling drill a42. The height of the pre-drilling drill a42 is about 3 mm, and the height of the main cutting plate a411 is about 4 times the height of the pre-drilling drill a42.

[0029] Furthermore, a V-shaped blade with an opening facing upward is formed at the bottom of the pre-drilling drill bit a42, thereby improving the ability to penetrate into the pad and the ability to tear open.

[0030] The main cutting plate a411 is located on both sides of the pre-drilling drill bit a42 in the horizontal direction and is respectively formed with main cutting edges a4111 extending obliquely upward to form a disconnected V-shaped structure, which also improves the ability of the main cutting plate a411 to rotate downward for cutting.

[0031] The auxiliary cutting plates a412 are integrally connected to both sides of the main cutting plate a411 in the plate direction. The auxiliary cutting plates a412 at the two plate surfaces are designed to be centrally symmetrical, and the auxiliary cutting plates a412 extend laterally from the middle of the main cutting plate a411 to the edge. The auxiliary cutting plate a412 has an arc-shaped cutting edge a4120, and the arc-shaped cutting edge a4120 preferably extends from the peripheral part of the mounting column a2 to the top position of the pre-drilling drill bit a42. The edge shape of the auxiliary cutting plate a412 on both sides of the width direction of the main cutting plate a411 should be consistent with the shape of the main cutting plate a411 to achieve the effect of side cutting. In addition, the arc-shaped cutting edge a4120 can also enhance the tearing ability of the middle area and minimize the problem of too many burrs.

[0032] Preferably, the top of the main cutting plate a411 is integrally connected to a radial line of the mounting column a2 to optimize the structure. The mounting column a2 is formed with an inclined guide surface a20 inclined upward to optimize the structure and force distribution, and at the same time, the cut pieces can have space for external discharge and can also be guided.

[0033] This embodiment also provides a mattress punching device, including the aforementioned mattress punching cutter head, and the mattress punching device can be applied to a mattress production line. The specific mattress punching device and mattress production line can adopt the structure of the embodiments described later.

[0034] Embodiment 2, as Figure 1-7 As shown, a magnetic particle conveying device for a mattress includes a row of magnetic particle falling guide cylinders b2 arranged in a left-right direction and used for magnetic particles to fall into the holes of a flexible pad. The magnetic particle falling guide cylinders b2 are upright and connected to a magnetic particle transverse conveying path c1 extending forward. The magnetic particle transverse conveying path c1 is connected to an upright entry channel c2. Magnetic particles can continuously enter the entry channel c2 from above and can be accumulated up and down. Then, through the horizontal and lateral conveying of the magnetic particles by the magnetic particle transverse conveying path c1, the magnetic particles can enter the magnetic particle falling guide cylinder b2. The magnetic particle falling guide cylinder b2 can drop the magnetic particles into the holes of the flexible pad, thereby realizing the automatic conveying process of the magnetic particles. The front-to-back direction involved in the embodiment refers to the front-to-back direction of the production line, the rear is the upstream end, and the front is the downstream end, that is, the production line of the mattress production process is carried out from the back to the front. Here, the magnetic particles are preferably input from the front to the back, because there are many previous process structures behind the magnetic particle falling guide cylinder b2, so that the space can be used more reasonably.

[0035] As a preference, all magnetic particle falling guide cylinders b2 are mounted on an integrated mounting support plate 3. The integrated mounting support plate 3 is a whole piece of aluminum alloy with an existing mounting flat plate structure, and of course, a number of hole structures are provided, and the magnetic particle falling guide cylinders b2 can be mounted on this integrated mounting support plate 3.

[0036] Preferably, a magnetic particle conveying guide rail c3 is arranged above the entry channel c2, and a soft connecting pipe c4 is connected between the entry channel c2 and the magnetic particle conveying guide rail c3. The magnetic particle conveying guide rail c3 can adopt an arc-shaped track, and the soft connecting pipe c4 can adopt a plastic tube. The magnetic particle conveying guide rail c3 is equipped with an existing electric push rod or a pushing wheel and other structures, so that the magnetic particles placed on the magnetic particle conveying guide rail can be pushed into the soft connecting pipe c4 and fall into the entry channel c2. The entry channel c2 can adopt a channel structure formed by a steel pipe.

[0037] The magnetic particle falling guide cylinder b2 is provided with a lifting rod c5 that can lift up and down to press the magnetic particles against the flexible pad hole. The magnetic particle transverse conveying path c1 is connected to a position between the upper and lower parts of the magnetic particle falling guide cylinder b2, so that the lifting rod c5 can conveniently press the magnetic particles into the flexible pad hole. The lifting rod c5 can adopt the piston rod structure of the pneumatic cylinder, but it is best to fix a pressing block structure similar to the shape of the magnetic particles at the lower end of the piston rod, so that after the magnetic particles fall into the flexible pad hole, the lifting rod c5 presses down to better bond the magnetic particles to the flexible pad hole. Of course, before the magnetic particles fall, glue needs to be dripped into the flexible pad hole.

[0038] The magnetic particle transverse conveying path c1 is provided with a push plate c6 for pushing the magnetic particles to be conveyed backwards, and the push plate c6 is connected to a transverse front-rear telescopic pneumatic cylinder c7. This design is to enable the magnetic particles that are at the bottom after the magnetic particles entering the channel c2 are accumulated and are already in the magnetic particle transverse conveying path c1 to be pushed backwards and conveyed into the magnetic particle falling guide cylinder b2.

[0039] A more important design is that the outer periphery of the bottom of the magnetic particle falling guide cylinder b2 is connected with a shielding protection plate c8. The shielding protection plate c8 can adopt a rectangular plate structure. The function of this is to prevent some semi-cured glue threads formed after the previous glue coating from sticking excessively to the lower mouth of the magnetic particle falling guide cylinder b2 and causing blockage. The structure of the shielding protection plate c8 can bond these glue threads more. In addition, in the process of the magnetic particles falling, it is possible that the position is abnormal and the particles are drilled to the outside of the flexible pad hole. This structure tries to prevent the magnetic particles from moving after falling.

[0040] This embodiment also provides a mattress magnetic particle installation device, including the aforementioned mattress magnetic particle conveying device. It also includes a conveyor belt 1 and a mattress punching device for punching holes in the flexible pad and a hole glue dripping device for applying glue to the flexible pad holes formed after the flexible pad is punched. The mattress punching device and the hole glue dripping device can adopt the structures mentioned in the subsequent embodiments.

[0041] This embodiment also provides a mattress production line, including the above-mentioned mattress magnetic particle installation device. Various structures on the production line can be used in combination with other embodiments.

[0042] Embodiment 3, as Figure 1-7 As shown, a mattress magnetic particle installation device includes a conveyor belt 1 and a mattress punching device for punching holes in a flexible pad, a hole glue dripping device for applying glue to the flexible pad holes formed after the flexible pad holes are punched, and a mattress magnetic particle conveying device for filling magnetic particles into the flexible pad holes. The mattress punching device has a row of mattress punching cutter heads arranged at intervals in the left and right directions and used for rotating holes in the flexible pads. The hole glue dripping device has a row of glue dripping cylinders b1 arranged at intervals in the left and right directions and used for dripping glue on the flexible pad holes. The mattress magnetic particle conveying device has a row of magnetic particle falling guide cylinders b2 arranged at intervals in the left and right directions and used for magnetic particles to fall into the flexible pad holes.

[0043] Preferably, a dust collecting device for cleaning the mattress is provided at the rear of the mattress punching device. The dust collecting device includes a dust collecting hood 2 extending in the left and right directions and opening downward. The upper part of the dust collecting hood 2 needs to be connected to an exhaust device such as a vacuum cleaner, mainly to promptly process the flexible pad block debris torn by punching, to ensure the cleanliness of the flexible pad block, and to produce a high-quality mattress.

[0044] Furthermore, the glue-dropping cylinder can be raised and lowered. The mattress punching cutter head can be raised and lowered. They can all be installed on a lifting motor or a lifting cylinder that can be raised and lowered and an existing lifting structure. The mattress punching cutter head is installed on the punching rotary motor a1, and the punching rotary motor a1 can be further connected to a lifting structure to achieve lifting, and the glue-dropping cylinder can be directly connected to a lifting structure for lifting.

[0045] Preferably, the mattress punching cutter head, glue dripping cylinder and magnetic particle falling guide cylinder are all installed on the same integrated mounting support plate 3 located above the conveyor belt 1. The aforementioned lifting structures can be installed on the integrated mounting support plate 3, so that the mattress punching cutter head and glue dripping cylinder are also installed accordingly, and the non-lifting structure such as the magnetic particle falling guide cylinder can be directly erected on the integrated mounting support plate 3, or the magnetic particle transverse conveying path c1 can be installed on the integrated mounting support plate 3, and the magnetic particle falling guide cylinder has to pass through the integrated mounting support plate 3 up and down anyway. As long as these three functional modules are integrated together, the three processes of drilling flexible pad holes, dripping glue in the flexible pad holes, and fixing magnetic particles in the flexible pad holes can be completed continuously during the conveying process, which is very fast and effective.

[0046] Other specific structures of the mattress magnetic particle conveying device, the mattress hole punching device, the hole glue dripping device can also be used in combination with the structures involved in other embodiments.

[0047] This embodiment also provides a mattress production line, including the aforementioned mattress magnetic particle installation device. Other structures involved in the production line can also adopt the structures of other embodiments.

[0048] Embodiment 4, as Figure 1-7 As shown, a mattress production conveyor belt includes a circulating belt body d1, and the belt body d1 has rollers d2 for tensioning and transmission on the front and rear sides, and the inner side of the belt body d1 is a rough surface. For a mattress production line with a high degree of automation, the travel speed of the conveyor belt needs to be precisely controlled, otherwise it will affect the timing of each station and cause problems in a certain link. Therefore, the conveyor belt must be able to run well with the rollers and try not to slip, thereby causing a short pause, resulting in deviations in the production process time, and causing problems such as inaccurate position of the mattress structure layer, inaccurate magnetic particles, and skewed punching. Therefore, the inner side of the belt body d1 must be a rough surface.

[0049] Preferably, the connection direction of the end-to-end connection of the belt body is inclined to the left-right direction. This belt body d1 is usually a flat conveyor belt connected end to end, because such a long assembly line generally adopts a light conveyor belt structure, so this conveyor belt is generally used in connection. The inclined design can reduce the risk of slipping at the connection point at the roller. Specifically, the end-to-end connection of the belt body forms an inclined circuitous connection part d3 that is inclined to the left-right direction and sewn back and forth by a sewing thread. Since the sewing thread is usually relatively smooth, the roughness of the connection point will be reduced. In this case, this inclined manner can make the connection point always have a part without sewing thread in the left-right direction, so that the connection point of the belt body d1 is not easy to slip when passing through the roller, because if a relatively straight sewing structure is adopted, then in a short time point, more sewing threads will contact with the roller to cause a short slip, thereby affecting the effectiveness of high-precision production, so this structural design of this embodiment is more in line with the purpose of precise transportation.

[0050] Preferably, the inclined circuitous connection portion d3 forms a V-shaped connection section that is continuous from left to right and alternately oriented front to back, thereby optimizing the structure.

[0051] The outer side of the belt body is a plastic surface or a plastic surface, such as nylon material, which is relatively light and has good structural strength. A plurality of block-shaped protrusions d4 are formed on the outer side of the belt body to ensure the friction force on the conveyor belt.

[0052] This embodiment also provides a mattress production equipment, that is, a mattress production line, including the aforementioned mattress production conveyor belt. It also includes a mattress punching device for punching holes in the flexible pad, a hole glue dripping device for applying glue to the flexible pad hole formed after the flexible pad is punched, and a mattress magnetic particle conveying device for filling magnetic particles into the flexible pad hole, which are arranged in sequence from back to front on the conveying path of the conveyor belt. The mattress punching device has a row of mattress punching heads arranged at intervals in the left and right directions and used to rotate and punch holes in the flexible pad, the hole glue dripping device has a row of glue dripping cylinders arranged at intervals in the left and right directions and used to drip glue on the flexible pad hole, and the mattress magnetic particle conveying device has a row of magnetic particle falling guide cylinders arranged at intervals in the left and right directions and used to let magnetic particles fall into the flexible pad hole.

[0053] The conveyor belt is provided with a manipulator on the side of the conveying path, and also includes a mattress cutting assembly at the front end of the conveyor belt.

[0054] The device structures other than the conveyor belts mentioned above may adopt the structures in other embodiments.

[0055] Embodiment 5, as Figure 1-7As shown, a mattress cutting table includes a support table e1, the support table is provided with at least two support plates e2 that can be lifted up and down for supporting the mattress, a cutting knife e3 is provided on the side of the support table, and the support table is equipped with a cutting positioning device that can press down the mattress for cutting. The initial mattress product also needs to be trimmed to reach the expected size, the cutting positioning device can better adjust and press the mattress, the cutting knife e3 can cut on the side, and the cut part on the side can be collected on the side, and the function of the support plate e2 is to enable the final product to be lifted and lowered after cutting, so that the finished mattress can be easily carried away.

[0056] Preferably, the support platform e1 is provided with a first embedding groove channel e4 for the support plate e2 to be lifted up and down, so that the table surface can be kept relatively intact before the finished mattress is transported, thereby ensuring the effectiveness of the cutting operation. The support plate e2 is equivalent to a part of the support platform e1 that can be lifted up and down.

[0057] The cutting knife e3 is a vertical flat blade, that is, the blade cuts in the horizontal direction. The cutting knife e3 can move in the horizontal direction. The cutting knife e3 can be installed on some existing mobile equipment. The table top of the support platform e1 is a smooth steel surface, which is convenient for the mattress products to be fed from the conveyor belt.

[0058] This embodiment also provides a mattress cutting assembly, including the aforementioned mattress cutting table and a mobile robot, the cutting positioning device includes a cutting manipulator connected to the mobile robot, the cutting manipulator includes a rectangular flat flattening support frame f1, a plurality of spaced flattening plates f2 are installed and connected below the flattening support frame f1, and the flattening plate f2 is provided with an insertion needle f3 for inserting into the mattress. The insertion needle f3 is installed and fixed on the side of the flattening support frame f1. A pressing counterweight f7 is fixed on the upper surface of the flattening plate f2 at both ends, and the insertion needle f3 also passes through the pressing counterweight f7 up and down, and the pressing counterweight f7 is installed on the side of the flattening support frame f1 through a lifting connection column f4 that can be lifted and lowered. The specific expansion of the technical content of this paragraph will be described in the subsequent embodiments, and will not be repeated here. The main purpose is to be able to press the mattress for cutting, and also to pull the mattress for turning, transportation, etc.

[0059] This embodiment also provides a mattress production line, including a conveyor belt and a first glue spraying device, a mattress punching device for punching holes in the flexible pad, a hole glue dripping device for applying glue to the flexible pad holes formed after the flexible pad holes are punched, a mattress magnetic particle conveying device for filling magnetic particles into the flexible pad holes, a second glue spraying device, a drying device, and a mattress cutting assembly as described above at the front end of the conveyor belt. Various device-like structures can also be used in combination with other embodiments.

[0060] Embodiment 6, as Figure 1-7 As shown, a mattress production line includes a conveyor belt and a first glue spraying device g1 arranged above the conveyor belt from back to front, a mattress punching device for punching holes in a flexible pad, a hole glue dripping device for applying glue to the holes of the flexible pad formed after the flexible pad is punched, and a mattress magnetic particle conveying device for filling magnetic particles into the holes of the flexible pad, a second glue spraying device g2, and a drying device h, and also includes a mattress cutting assembly arranged at the front end outlet of the conveyor belt. The device structure can adopt the specific structure in other embodiments, and the production process will be introduced later. The drying device h can adopt the existing drying equipment.

[0061] Preferably, the first glue spraying device includes glue spraying guns g arranged at intervals on the left and right. The second glue spraying device includes glue spraying guns g arranged at intervals on the left and right. The glue spraying guns can be installed on some support frames, and the gun heads are sprayed downward. The spraying time and spraying amount can be controlled by automatic control equipment. The gun heads are preferably scattered holes, so that the spraying can be more uniform, mainly to make the surface of the sprayed pad more uniform and more effectively coated with water, reducing waste.

[0062] The present embodiment provides a mattress production process, comprising the following steps: 1. placing a base support block on a conveyor belt and spraying glue on the surface through a first glue spraying device; 2. laying a flexible pad block in the middle; 3. punching holes in the flexible pad block, dripping glue, and placing magnetic particles; 4. spraying glue on the surface of the flexible pad block through a second glue spraying device; 5. laying a surface pad block on the flexible pad block; 6. drying; 7. cutting.

[0063] The base support block usually adopts a hard polyethylene or polypropylene foam bridge. The base support block can be automatically placed on the conveyor belt by a grabbing robot, and then the upper surface is sprayed with glue. The flexible pad block can be laid on the upper surface of the base support block after spraying with glue by a grabbing robot to complete the preliminary installation process. The flexible pad block can be a sponge block; then the flexible pad block is punched, glue is dripped, and magnetic particles are placed. The above production line is equipped with a corresponding device structure to process the flexible pad block and complete the installation of magnetic particles; then, the upper surface of the flexible pad block is also sprayed with glue, and the surface pad block can be grabbed by a grabbing robot and laid on the upper surface of the flexible pad block, so that the structure of the entire mattress is basically formed. The surface pad block can be a latex block; then the glue is dried and solidified to fix the shape, and then it is transported to the front end of the mattress cutting assembly for cutting and transportation.

[0064] The whole process is more efficient than before. The gripping manipulators of the base support block, the flexible pad block, and the surface pad block can adopt the existing gripping manipulators, or the manipulator structure in Example 8. In addition, it is more important that the flexible pad block is punched into half holes in step 3. In addition, some motor structures, telescopic structures, or lifting structures mentioned in this application can be automatically controlled by an automatic control system to achieve efficient automated production.

[0065] Embodiment 7, as Figure 1-7As shown, a manipulator for cutting in mattress production, that is, a cutting manipulator, can be connected to a mobile robot, so that it can be convenient to adjust its position in all directions, and the cutting manipulator of this embodiment includes a flat flat rectangular support frame f1, the upper part of the flattening support frame f1 can be connected to the robot, the robot can use an existing robot that can walk and has a movable arm, and the movable arm can be connected to the flattening support frame f1. It will not be elaborated in detail here, and it is a very easy to implement structure. A plurality of spaced-apart flat plates f2 are installed and connected at the bottom of the flattening support frame f1 and are used to directly press the mattress and can be raised and lowered. Insertion needles f3 for inserting into the mattress are penetrated from top to bottom at the flattening plate f2, and pressing counterweight blocks f7 are fixed on the upper surface of the flattening plate f2 near both ends. The insertion needle f3 can also pass through the pressing counterweight block f7 up and down, and corresponding upper and lower through holes are provided on the pressing counterweight block f7 and the flattening plate f2 for the insertion needle f3 to pass up and down. The flat plate f2 can be a rectangular flat plate structure. The pressing counterweight f7 and the flat plate f2 can of course be steel structures. When cutting, the flat plate f2 and the counterweight move down with the flattening support frame f1 to flatten the mattress by weight to make the mattress firm. At the same time, the insertion needle f3 is gradually inserted into the mattress. Since the pressing counterweight f7 and the flat plate f2 can be freely raised and lowered, they will not fall when they are pressed to a certain degree, and the insertion needle f3 can still be inserted for a section to ensure the stability of the plug-in. At this time, the flattening support frame f1 can be adjusted in position, for example, rotated, etc. After adjusting to the corresponding position, it can be cut by a cutting knife. The pressing counterweight f7 requires a larger counterweight, generally preferably more than 1 kg and less than 5 kg. This makes the mattress flat when the mattress is pressed and cut. After cutting, the flattening support frame f1 is lifted up, and the pressing counterweight f7 has enough weight to ensure that the mattress and the insertion needle f3 are separated from each other. The insertion needle f3 of this manipulator is vertical, not like the inclined setting for grabbing. In addition, the pressing weight f7 can be filled with wool felt coated with lubricating oil, so that the insertion needle f3 remains lubricated, which facilitates insertion without damaging the mattress.

[0066] Some specific optimizations, the pressing weight f7 is in the shape of a round cake. The insertion needle f3 is installed and fixed on the side of the flattening support frame f1.

[0067] Furthermore, the pressing counterweight f7 is installed on the side of the flattening support frame f1 through a lifting connection column f4 that can be lifted and lowered. The lower end of the lifting connection column f4 is fixed to the pressing counterweight f7. The side of the flattening support frame f1 is fixed with a mounting block f0. The mounting block f0 is provided with a lifting passage f01 for the lifting connection column f4 to pass through and can pass up and down. The upper end of the lifting connection column f4 is fixed with a limit head f40 to prevent it from falling down. The limit head f40 is located above the lifting passage f01. The size of the limit head f40 is larger than the caliber of the lifting passage f01. In this way, the lifting connection column f4 will not fall down. Preferably, the insertion needle f3 is directly fixed to the lower side of the mounting block f0.

[0068] Preferably, the side of the flattening support frame f1 is equipped with a conveying roller f5 and a motor f6 for conveying the mattress. The motor f6 is fixed to the flattening support frame f1. The conveying roller f5 is axially in the horizontal direction. The conveying roller f5 is installed on the shaft of the motor f6, and the wheel surface of the conveying roller f5 serves as the supporting surface. Furthermore, the top of the conveying roller f5 is higher than the flattening support frame f1. The advantage of this is that the manipulator can not only be used for cutting, but also the mattress can be transported by lifting the mattress through the aforementioned support plate e2, and then the flattening support frame f1 is extended to the bottom of the mattress and then raised. Due to the design of the conveying roller f5, the mattress supported by the flattening support frame f1 can be supported by the conveying roller f5 and then transported to the corresponding container or other places for storage. In addition, if two support plates e2 are used, the lateral spacing between the two support plates e2 is preferably large enough, so that the manipulator can be placed more under the mattress to better transport the mattress.

[0069] Further optimized, the conveying roller f5 includes a cylindrical wheel body f51 and supporting spikes f52 distributed in a circular array fixed on the outer periphery of the wheel body f51, which can better ensure the effectiveness of transporting mattresses.

[0070] This embodiment also provides a mattress production line, including the aforementioned robot. It also includes a conveyor belt and a first glue spraying device, a mattress punching device for punching holes in the flexible pad, a hole glue dripping device for applying glue to the holes of the flexible pad formed after the flexible pad is punched, and a mattress magnetic particle conveying device, a second glue spraying device, and a drying device for filling magnetic particles into the holes of the flexible pad. It also includes a mattress cutting assembly at the front end of the conveyor belt, and the mattress cutting assembly is as close as possible to the front end exit of the conveyor belt to facilitate the receipt of the mattress. These device structures can also refer to the aforementioned embodiments.

[0071] Embodiment 8, as Figure 1-7As shown, a manipulator for grabbing and laying mattresses in mattress production includes a movable support and laying frame k1 connected to a robot. The movable support and laying frame k1 is a rectangular frame and is moved by the robot. Insertion needles f3 that can move up and down are arranged at the peripheral position of the movable support and laying frame k1. The insertion needles f3 are arranged on a floating device. This allows the uneven pads to be flattened when being grabbed, as long as the movable support and laying frame k1 is lowered a little more.

[0072] Preferably, there are a plurality of insertion needles f3 which are arranged crosswise at an angle to the horizontal direction, and are arranged in the inner and outer directions of the edge of the movable supporting horizontal frame k1 to form a cross state.

[0073] The side of the movable support horizontal frame k1 is equipped with a mounting guide seat k2 for the insertion needle to pass through for installation. Of course, the upper position of the mounting guide seat k2 should be equipped with a telescopic structure such as a small cylinder connected to the top of the insertion needle and for the insertion needle to extend and retract obliquely. The floating device includes a floating plate k3 for the mounting guide seat k2 to be installed and connected and can float up and down. The floating plate k3 is upright and can be close to the side of the movable support horizontal frame k1. The extension direction of the mounting guide seat k2 and the insertion needle installed thereon are kept consistent as much as possible, so it is also inclined. The lower part of the floating plate k3 can be fixedly connected to the mounting guide seat k2 by welding or screwing, and a fixed connecting plate k8 is connected between the floating plate k3 and the mounting guide seat k2. The fixed connecting plate k8 connects the floating plate k3 and the mounting guide seat k2 together. Specifically, a laterally extending support beam k4 is installed on the movable support horizontal frame, and an up-and-down moving groove k5 is provided on the floating plate k3 for the support beam k4 to pass through laterally and move up and down, so that the floating plate k3 has sufficient free upward and downward movement ability.

[0074] Furthermore, a floating plate k3 is disposed on both sides of the movable support horizontal frame k1, and the bottoms of the two floating plates k3 are simultaneously connected to a bottom connecting block k6. The bottom of the bottom connecting block k6 is connected to a needle tip guiding pressing plate k7 extending downward and through which the needle tip of the needle f3 passes. The bottom surface of the needle tip guiding pressing plate k7 is horizontal. The needle tip guiding pressing plate k7 can preferably be a rectangular segment extending straight up and down fixedly connected to the bottom of the bottom connecting block k6 and an isosceles trapezoidal segment fixedly connected to the bottom of the rectangular segment. The insertion needles f3 on both sides can cross and pass through the waist of the isosceles trapezoidal segment. In this way, when the movable supporting flat frame k1 continues to move downward, not only can the insertion needle f3 be effectively inserted into the pad, but the counterweight of the needle tip guiding pressing plate k7 itself can also be used to flatten the uneven pad. Moreover, the structure of the floating plate can be used to flatten the pad better and more adaptively. Of course, as many floating plates k3 as possible should be set, and not all insertion needles should act on only one or two floating plates, so that each area can have more room for adjustment.

[0075] This embodiment also provides a mattress production line, including the aforementioned manipulator, a conveyor belt, and a first glue spraying device, a mattress punching device for punching holes in the flexible pad, a hole glue dripping device for applying glue to the flexible pad holes formed after the flexible pad holes are punched, and a mattress magnetic particle conveying device, a second glue spraying device, and a drying device for filling magnetic particles into the flexible pad holes. It also includes a mattress cutting assembly arranged at the front end of the conveyor belt. The specific structure can refer to the aforementioned embodiment.
