Description

Technical Field

[0001] This invention relates to the field of product packaging technology, and in particular to a foam pad packaging device. Background Technology

[0002] Foam pads are flexible components made of foamed materials (such as polyurethane, silicone, EVA, foam adhesive, etc.). They have elastic deformation capabilities and can be used as protective parts during equipment assembly or transportation. Produced foam pads need to be stacked in a certain quantity. To protect the stacked foam pads, partitions are usually added to the top and bottom sides, and areas with grooves on the outside are filled with sponge blocks. Finally, the products are packaged with packing tape.

[0003] However, the varying positions of different foam pads on the conveyor belt mean that manual operation is still required when placing sponge blocks into the stacked foam pads, thus reducing the packaging efficiency of the foam pads. Summary of the Invention

[0004] The present invention addresses the problem that the varying positions of different foam pads on the conveyor belt necessitate manual operation when inserting sponge blocks into stacked foam pads, thus reducing the packaging efficiency of foam pads. The invention aims to provide a foam pad packaging device that overcomes or at least partially solves the aforementioned problems.

[0005] This invention provides a foam pad packaging device, the foam pad packaging device comprising: Support base; A first transmission component is mounted on the support base; A first blocking component is mounted on the support base and located at the first end of the first conveying component. When the first blocking component moves upward, it blocks the foam padding on the first conveying component. Two first telescopic positioning components are distributed on both sides of the first conveying component and installed on the support base. When the two first telescopic positioning components extend relative to each other, they position the foam pad stack that is blocked by the first blocking component. A sponge robot assembly, located at the first end of the first conveying assembly, is used to grasp sponge blocks and place them into the grooves of the positioned foam pad stack.

[0006] In one optional embodiment of the invention, the first blocking assembly includes a first blocking telescopic member and a first blocking plate. The output shaft of the first blocking telescopic member is parallel to the vertical direction and is connected to the first blocking plate in a transmission manner. When the first blocking telescopic member extends, it drives the first blocking plate to rise and contact the foam padding surface to block the foam padding. The first telescopic positioning assembly includes a first positioning telescopic member and a first positioning plate. The output shaft of the first positioning telescopic member is parallel to the horizontal direction and is connected to the first positioning plate in a transmission manner. When the two first positioning telescopic members extend relative to each other, they drive the two first positioning plates to form surface contact with the two sides of the foam pad stack.

[0007] In one optional embodiment, the foam pad packaging equipment further includes a pad stacking and transfer assembly, the pad stacking and transfer assembly comprising: Transfer robotic arm; A padding clamping unit is connected to the end of the transfer robotic arm, and the padding clamping unit clamps the foam padding. The pallet pressing expansion joint is connected to the pallet clamping unit via a transmission mechanism. The lower pressure plate of the padding is connected to the lower pressure telescopic device of the padding. When the lower pressure telescopic device of the padding extends, the lower pressure plate of the padding descends and abuts against the foam padding held by the padding clamping unit, so as to cooperate with the padding clamping unit to lock the position of the foam padding.

[0008] In one optional embodiment, the pad clamping unit comprises: A bidirectional telescopic palletizer is provided, which is connected to the end of the transfer robotic arm. Two padding clamps are provided, and the two padding clamps are respectively connected to the two output shafts of the bidirectional expansion joint of the padding. The padding clamps are L-shaped structures. When the bidirectional expansion joint of the pad is retracted, the two pad clamping members move in a straight line closer to each other to clamp the foam pad on three sides.

[0009] In one optional embodiment, the first transmission component includes: At least two first conveying shafts are distributed at intervals along the conveying direction and are rotatably connected to the support base; At least four first transmission wheels, with two first transmission wheels respectively connected to each first transmission shaft; Two conveyor belts, the first conveyor belt is driven and engaged with all the first conveyor wheels on the first side of the first conveyor shaft respectively, and the second conveyor belt is driven and engaged with all the first conveyor wheels on the second side of the first conveyor shaft respectively. The upper surfaces of the two conveyor belts support the foam pads, and a blocking movement channel is formed between the two conveyor belts for the first blocking assembly to move upward. A first transmission driver is mounted on the support base and is connected to one of the first transmission shafts. When the first transmission driver is working, it drives the first transmission shaft to rotate and drives the conveyor belt to rotate and transport the foam pad stack.

[0010] In one optional embodiment, the foam pad packaging device further includes a first feeding assembly, the first feeding assembly comprising: The first feeding base is used to place the pad; A feeding baffle is installed on the first feeding base and cooperates with the first feeding base to form a feeding guide channel for a single layer of pad to pass through. The first unloading conveying unit is installed on the first unloading base. When the first unloading conveying unit is working, it drives the pad through the unloading guide channel and conveys it to the second end of the first conveying component. A pressure roller is rotatably connected to the first feeding base and forms a pressure contact with the pad that passes through the feeding guide channel.

[0011] In one optional embodiment, the first feeding assembly further includes two first feeding limiting members, which are spaced apart on the first feeding base and cooperate to form a feeding limiting channel distributed along the length direction of the first feeding conveying unit, so as to limit the movement trajectory of the pad through the feeding limiting channel.

[0012] In one optional embodiment, the foam pad packaging device further includes a second feeding component and a feeding transfer component, wherein the second feeding component and the first feeding component have the same structure, and the feeding transfer component includes: Material feeding conveyor base; The second unloading conveying unit is mounted on the unloading conveying base, and the first end of the second unloading conveying unit is in transmission cooperation with the second unloading component; The second material feeding blocking unit is installed on the material feeding conveying base and is located at the second end of the second material feeding conveying unit. When the second material feeding blocking unit moves upward, it blocks the pad on the second material feeding conveying unit. Two second telescopic positioning units are distributed on both sides of the second unloading conveying unit and installed on the unloading conveying base. When the two second telescopic positioning units extend relative to each other, they position the pad that is blocked by the second unloading blocking unit. A pad transfer unit is located above the second telescopic positioning unit and is used to transfer the pad to the top of a foam pad stack filled with sponge blocks.

[0013] In one optional embodiment, the pad transfer unit comprises: A transfer frame, which is located above the second telescopic positioning unit; A linear actuator for transport, which is mounted on the transport frame; A transfer lifter is connected to the transfer linear drive, and when the transfer linear drive is working, it drives the transfer lifter to perform reciprocating linear motion in the horizontal direction. At least one transfer suction cup is mounted on the output shaft of the transfer lifter. The transfer suction cup is used to adsorb the pad. When the transfer lifter is working, the transfer suction cup moves up and down.

[0014] In an optional embodiment, the foam pad packaging device further includes: Foam stacking base; A stacking conveyor assembly is installed on the foam stacking base. When the stacking conveyor assembly is in operation, it conveys the foam pad from the first end of the stacking conveyor assembly to the second end of the stacking conveyor assembly. A stacking receiving assembly is located at the first end of the stacking conveying assembly. When the stacking receiving assembly is in an upward state, the top of the stacking receiving assembly receives the foam pad. When the stacking receiving assembly is lowered to its lowest position, the top of the stacking receiving assembly is lower than the conveying surface of the stacking conveying assembly, so that the foam pad located on the stacking receiving assembly is conveyed by the stacking conveying assembly to the clamping area of ​​the pad clamping unit.

[0015] In one optional embodiment, the stacking support assembly includes: A limiting platform is installed on the foam stacking base and located above the stacking conveying assembly. The limiting platform and the stacking conveying assembly cooperate to form a stacking guide channel for the passage of multi-layer stacked foam pads. A stacking limiting component is located at the first end of the stacking conveying assembly and is fixedly connected to the foam stacking base. At least two stacking positioning units are distributed on the limiting platform and cooperate with the stacking limiting member to form at least three-sided limiting of the foam pad stack. A stacking lifter, which is installed on the foam stacking base; A stacking support is provided, which is connected to the output shaft of the stacking lifter. When the stacking lifter raises the stacking support to its highest position, the stacking support is higher than the conveying surface of the stacking conveying assembly, so that the foam pads are stacked on the stacking support. When the stacker lift lowers the stacking support to its lowest position, and the stacking support is lower than the conveying surface of the stacking conveyor assembly, the stacking conveyor assembly receives the foam pad and conveys it.

[0016] In one optional embodiment, the foam pad packaging equipment further includes a negative pressure conveying device located above the stacking receiving assembly. The distance between the stacking positioning unit and the bottom of the negative pressure conveying device is less than the thickness of a single layer of the foam pad, so that the single layer of foam pad conveyed from the bottom of the negative pressure conveying device is confined on the stacking support for stacking.

[0017] In one optional embodiment, the foam pad packaging equipment further includes a strapping machine located at one end of the transfer frame away from the sponge robot assembly, wherein the strapping machine straps the foam pad stack with the top pad placed on it during operation.

[0018] Compared with existing technologies, this invention includes a support base, a first conveying component, a first blocking component, two first telescopic positioning components, and a sponge robot component. The first conveying component is mounted on the support base, and the first blocking component is mounted on the support base and located at the first end of the first conveying component. When the first blocking component moves upward, it blocks the foam pad stack on the first conveying component. The two first telescopic positioning components are distributed on both sides of the first conveying component and mounted on the support base. When the two first telescopic positioning components extend relative to each other, they position the foam pad stack blocked by the first blocking component. The sponge robot component is located at the first end of the first conveying component and is used to grasp sponge blocks and place them into the grooves of the positioned foam pad stack. Thus, the foam pad stack conveyed from the first conveying component is limited on three sides by the extension and cooperation of the first blocking component and the first telescopic positioning component. This allows for precise positioning of the groove positions of the foam pad stack, and finally, the sponge robot component inserts the sponge blocks into the foam pad stack, thereby greatly improving the packaging efficiency of the foam pads.

[0022] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0023] Foam pads are flexible components made of foamed materials (such as polyurethane, silicone, EVA, foam adhesive, etc.). They have elastic deformation capabilities and can be used as protective parts during equipment assembly or transportation. Produced foam pads need to be stacked in a certain quantity. To protect the stacked foam pads, partitions are usually added to the top and bottom sides, and areas with grooves on the outside are filled with sponge blocks. Finally, the products are packaged with packing tape.

[0024] However, the varying positions of different foam pads on the conveyor belt mean that manual operation is still required when placing sponge blocks into the stacked foam pads, thus reducing the packaging efficiency of the foam pads.

[0025] Based on the aforementioned technical problems, this application proposes an embodiment that may include a support base, a first conveying component, a first blocking component, two first telescopic positioning components, and a sponge robot component. The first conveying component is mounted on the support base, and the first blocking component is mounted on the support base and located at the first end of the first conveying component. When the first blocking component moves upward, it blocks the foam pad stack on the first conveying component. The two first telescopic positioning components are distributed on both sides of the first conveying component and mounted on the support base. When the two first telescopic positioning components extend relative to each other, they position the foam pad stack blocked by the first blocking component. The sponge robot component is located at the first end of the first conveying component and is used to grasp sponge blocks and place them into the grooves of the positioned foam pad stack. Thus, the foam pad stack conveyed from the first conveying component is limited on three sides by the extension and cooperation of the first blocking component and the first telescopic positioning component. This allows for precise positioning of the groove positions of the foam pad stack, and finally, the sponge robot component inserts the sponge blocks into the foam pad stack, thereby greatly improving the packaging efficiency of the foam pads.

[0026] Reference Figure 1-9 This application provides a foam pad 1510 packaging device, which may include a support base 100, a first conveying component 200, a first blocking component 300, two first telescopic positioning components 400, and a sponge robot component 500. The first conveying component 200 is mounted on the support base 100, and the first blocking component 300 is mounted on the support base 100 and located at the first end of the first conveying component 200. When the first blocking component 300 moves upward, it blocks the foam pad stack 1500 on the first conveying component 200. The two first telescopic positioning components 400 are distributed on both sides of the first conveying component 200 and mounted on the support base 100. When the two first telescopic positioning components 400 extend relative to each other, they position the foam pad stack 1500 blocked by the first blocking component 300. The sponge robot component 500 is located at the first end of the first conveying component 200 and is used to grasp sponge blocks 1600 and place them into the grooves 1501 of the positioned foam pad stack 1500.

[0027] In this embodiment, the support base 100 provides structural support for equipment-related components such as the first conveying component 200, the first blocking component 300, and the first telescopic positioning component 400. The first conveying component 200 is used to convey foam pad stacks 1500. A foam pad stack 1500 refers to a stack of two or more foam pads 1510. When the first conveying component 200 is operating, it can convey the foam pad stacks 1500 located on the first conveying component 200 from the second end of the first conveying component 200 to the first end of the first conveying component 200.

[0028] The first blocking component 300, the first conveying component 200, and the first telescopic positioning component 400 can all be mounted on the support base 100. The first blocking component 300 is located at the first end of the first conveying component 200 and is used to block the foam pad stack 1500 located on the first conveying component 200. The first blocking component 300 can move up and down during operation. When the first blocking component 300 is moving upward or in a raised state, it limits the foam pad stack 1500 located on the first conveying component 200 along the conveying direction of the first conveying component 200. When the first blocking component 300 is moving downward or in a lowered state, it is lower than the conveying surface of the first conveying component 200, so the foam pad stack 1500 located on the first conveying component 200 can continue to be conveyed, thereby allowing the foam pad stack 1500 to enter the next packaging process.

[0029] Two first telescopic positioning components 400 are distributed on both sides of the first conveying component 200, specifically on both sides of the first conveying component 200 along its width. The first telescopic positioning components 400 perform telescopic movements during operation. When the two first telescopic positioning components 400 extend in opposite directions, they respectively abut against both sides of the foam pad stack 1500 blocked by the first blocking component 300, thereby limiting the foam pad stack 1500 on three sides and precisely positioning the groove 1501 of the foam pad stack 1500. In other words, the position of each group of foam pad stacks 1500 after being limited by the first blocking component 300 and the two first telescopic positioning components is consistent, that is, the position of the groove 1501 of each group of foam pad stacks 1500 is also consistent.

[0030] The sponge robot assembly 500 is located at the first end of the first conveying assembly 200. It is used to grasp the sponge block 1600 and deliver the grasped sponge block 1600 into a preset groove 1501, thereby enabling the sponge block 1600 to be placed into the groove 1501 of the foam pad stack 1500. For example, the sponge robot assembly 500 may include a robotic arm and a sponge suction cup connected to the end of the robotic arm. The sponge suction cup can adsorb the sponge block 1600 and place it into the groove 1501.

[0031] Based on the above structural design, the foam pad stack 1500 conveyed from the first conveying component 200 can be three-sidedly limited by the extension and cooperation of the first blocking component 300 and the first telescopic positioning component 400. This precisely positions the groove 1501 of the foam pad stack 1500, and finally, the sponge robot component 500 inserts the sponge block 1600 into the foam pad stack 1500, thereby greatly improving the packaging efficiency of the foam pad 1510.

[0032] In one or more embodiments, refer to Figure 2 As shown, the first blocking assembly 300 may include a first blocking telescopic member 310 and a first blocking plate 320. The output shaft of the first blocking telescopic member 310 is parallel to the vertical direction and is convectively connected to the first blocking plate 320. When the first blocking telescopic member 310 extends, it drives the first blocking plate 320 to rise and contact the foam pad stack 1500 surface, thereby blocking the foam pad stack 1500. The first telescopic positioning assembly 400 may include a first positioning telescopic member 410 and a first positioning plate 420. The output shaft of the first positioning telescopic member 410 is parallel to the horizontal direction and is convectively connected to the first positioning plate 420. When the two first positioning telescopic members 410 extend relative to each other, they drive the two first positioning plates 420 to form surface contact with both sides of the foam pad stack 1500.

[0033] In this embodiment, the first blocking assembly 300 may include a first blocking telescopic device 310 and a first blocking plate 320. The first blocking telescopic device 310 may include, but is not limited to, a cylinder, an electric cylinder, a hydraulic cylinder, and an electric telescopic tube. The output shaft of the first blocking telescopic device 310 is arranged parallel to the vertical direction and is connected to the first blocking plate 320 in a transmission manner. That is, when the first blocking telescopic device 310 is working to extend or retract, it can realize the vertical lifting and lowering of the output shaft, and simultaneously drive the first blocking plate 320 to lift and lower.

[0034] When the first obstruction telescopic device 310 extends, causing the first obstruction plate 320 to rise, the first obstruction plate 320 rises to a position above the conveying surface of the first conveying assembly 200, thereby making the first obstruction plate 320 contact the surface of the foam pad stack 1500 and preventing the foam pad stack 1500 from continuing to move along the conveying direction of the first conveying assembly 200. When the first obstruction telescopic device 310 retracts, causing the first obstruction plate 320 to descend, the first obstruction plate 320 descends to a position below the conveying surface of the first conveying assembly 200, thereby releasing the obstruction of the first obstruction plate 320 on the foam pad stack 1500, allowing the foam pad stack 1500 located on the first conveying assembly 200 to continue to be conveyed, and thus allowing the foam pad stack 1500 to be conveyed into the next packaging process.

[0035] The first telescopic positioning assembly 400 may include a first positioning telescopic device 410 and a first positioning plate 420. The first positioning plate 420 telescopic device may include, but is not limited to, devices such as cylinders, electric cylinders, hydraulic cylinders, and electric telescopic tubes. The output shaft of the first positioning telescopic device 410 is parallel to the horizontal direction and is connected to the first positioning plate 420 in a transmission manner. That is, when the first positioning telescopic device 410 is working to extend or retract, it can realize the reciprocating linear motion of the output shaft along the horizontal direction, and can synchronously drive the first positioning plate 420 to make reciprocating linear motion toward or away from the first conveying assembly 200.

[0036] When the two first positioning telescopic joints 410 extend towards each other, they can form two-sided contact with the foam pad stack 1500 blocked by the first blocking assembly 300. When the two first positioning telescopic joints 410 retract away from each other, the foam pad stack 1500 blocked by the first blocking assembly 300 can be released from its position.

[0037] Based on the above structural design, the foam pad stack 1500 can be limited on three sides by the first blocking plate 320 and the two first positioning plates 420, and the contact area between the plate structure and the foam pad stack 1500 can be expanded, thereby improving the positioning accuracy of the groove 1501 of the foam pad stack 1500 and making it easier to improve the grasping efficiency of the sponge robot component 500 on the sponge block 1600.

[0038] In one or more embodiments, refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, the foam pad 1510 packaging equipment may further include a padding transfer assembly 600, which may include a transfer robotic arm 610, a padding clamping unit 620, a padding downward pressure telescopic device 630, and a padding downward pressure plate 640. The padding clamping unit 620 is connected to the end of the transfer robotic arm 610 and clamps the foam padding 1500. The padding downward pressure telescopic device 630 is drivenly connected to the padding clamping unit 620, and the padding downward pressure plate 640 is drivenly connected to the padding downward pressure telescopic device 630. When the padding downward pressure telescopic device 630 extends, the padding downward pressure plate 640 descends and abuts against the foam padding 1500 clamped by the padding clamping unit 620, so as to cooperate with the padding clamping unit 620 to lock the position of the foam padding 1500.

[0039] In this embodiment, the padding and transfer assembly 600 is used to transfer each stacked foam pad 1500. For example, it can transfer the foam pads 1500 from other transfer assemblies to the first transfer assembly 200. The padding and transfer assembly 600 may include a transfer robotic arm 610, a padding clamping unit 620, a padding pressure telescopic device 630, and a padding pressure plate 640. The transfer robotic arm 610 may include, but is not limited to, a six-axis robotic arm. The padding clamping unit 620 is connected to the end of the transfer robotic arm 610, so that the spatial position of the padding clamping unit 620 can be adjusted by the movement of the transfer robotic arm 610 to transfer the foam pads 1500.

[0040] The foam pad clamping unit 620 is used to clamp the foam pad stack 1500. For example, the foam pad clamping unit 620 abuts against the two opposite sides of the foam pad stack 1500 to clamp the foam pad stack 1500. The foam pad pressing telescopic device 630 may include, but is not limited to, cylinders, electric cylinders, hydraulic cylinders, and electric telescopic tubes. The foam pad pressing telescopic device 630 is drive-connected to the foam pad clamping unit 620. For example, the output shaft of the foam pad pressing telescopic device 630 is parallel to the vertical direction. The foam pad pressing plate 640 is fixedly connected to the output shaft of the foam pad pressing telescopic device 630. When the foam pad pressing telescopic device 630 extends, it can drive the foam pad pressing plate 640 to descend closer to the foam pad stack 1500 held by the foam pad clamping unit 620, and allow the foam pad pressing plate 640 to abut against the top of the foam pad stack 1500, thus cooperating with the foam pad clamping unit 620 to lock the position of the foam pad stack 1500. When the foam pad pressing telescopic device 630 retracts, it can drive the foam pad pressing plate 640 to rise away from the foam pad stack 1500, and release the position lock of the foam pad stack 1500.

[0041] Based on the above structural design, the coordinated operation of the transfer robotic arm 610, the stacking clamping unit 620, the stacking pressure telescopic device 630, and the stacking pressure plate 640 can achieve both neat stacking of the foam pads 1500 and lock their position, preventing them from shifting during transfer. This also further improves the positioning accuracy of the grooves 1501 in the foam pads 1500 and the packaging efficiency of the foam pads 1510.

[0042] In one or more embodiments, refer to Figure 4 As shown, the padding clamping unit 620 may include a bidirectional padding telescopic device 621 and two padding clamping members 622. The bidirectional padding telescopic device 621 is connected to the end of the transfer robotic arm 610. The two padding clamping members 622 are respectively drivenly connected to the two output shafts of the bidirectional padding telescopic device 621, wherein the padding clamping member 622 has an L-shaped structure. When the bidirectional padding telescopic device 621 retracts, the two padding clamping members 622 move in a straight line towards each other to clamp the foam padding 1500 on three sides.

[0043] In this embodiment, the padding clamping unit 620 may include a bidirectional padding telescoping device 621 and two padding clamping members 622. The bidirectional padding telescoping device 621 may include, but is not limited to, a bidirectional cylinder. The bidirectional padding telescoping device 621 is connected to the end of the transfer robotic arm 610, and the two padding clamping members 622 are respectively drivenly connected to the two output shafts of the bidirectional padding telescoping device 621. That is, when the two output shafts of the bidirectional padding telescoping device 621 extend in opposite directions, the two padding clamping members 622 move away from each other in a linear motion to increase the clamping space between the two padding clamping members 622, so that the foam padding 1500 can enter the clamping space.

[0044] For each of the padding clamping members 622, each padding clamping member 622 can be an L-shaped structure. Thus, after the foam padding 1500 enters the clamping space, when the two output shafts of the padding bidirectional telescoping device 621 retract in opposite directions, the two padding clamping members 622 move in a straight line closer to each other to reduce the clamping space between the two padding clamping members 622, so that the two sides of the foam padding 1500 abut against the two padding clamping members 622 respectively, and the bottom of the foam padding 1500 also abuts against the two padding clamping members 622.

[0045] Based on the above structural design, the movement of the two foam pad clamping members 622 can be controlled by the action of one of the two-way telescopic pads 621, thereby improving the ease of clamping the foam pad 1500. Furthermore, through the cooperation of the two foam pad clamping members 622 and the lower pressure plate 640, the foam pad 1500 can be limited on all four sides, thereby improving the clamping firmness of the foam pad clamping unit 620 on the foam pad 1500 and preventing the foam pad 1500 from shifting position during transport.

[0046] In one or more embodiments, refer to Figure 2 As shown, the first conveying assembly 200 may include at least two first conveying shafts 210, at least four first conveying wheels 220, two conveyor belts 230, and a first conveying driver 240. At least two first conveying shafts 210 are spaced apart along the conveying direction and rotatably connected to the support base 100. Each first conveying shaft 210 is driven by two first conveying wheels 220. A first conveyor belt 230 is driven by all the first conveying wheels 220 on the first side of the first conveying shafts 210, and a second conveyor belt 230 is driven by all the first conveying wheels 220 on the second side of the first conveying shafts 210. The upper surfaces of the two conveyor belts 230 support the foam pad 1500, and a blocking movement channel 2301 is formed between the two conveyor belts 230 for the first blocking assembly 300 to perform upward movement. The first transmission driver 240 is mounted on the support base 100 and is connected to one of the first transmission shafts 210. When the first transmission driver 240 is working, it drives the first transmission shaft 210 to rotate and drives the conveyor belt 230 to rotate and transport the foam pad stack 1500.

[0047] In this embodiment, the first conveying assembly 200 is integrally mounted on the support base 100 and may include at least two first conveying shafts 210, at least four first conveying wheels 220, two conveyor belts 230, and a first conveying driver 240. At least two first conveying shafts 210 are spaced apart along the conveying direction (also referred to as the conveying direction of the foam padding 1500). Both ends of each first conveying shaft 210 can be rotatably connected to a preset mounting position on the support base 100 via bearings, enabling the first conveying shaft 210 to rotate around its own axis under external force. The number of first conveying shafts 210 can be determined based on the required conveying length and is not limited here.

[0048] Two first transmission wheels 220 are fixedly connected to each first transmission shaft 210. The two first transmission wheels 220 are distributed at intervals along the axis of the first transmission shaft 210. For example, one first transmission wheel 220 may be located on the first side of the first transmission shaft 210, and the other first transmission wheel 220 may be located on the second side of the first transmission shaft 210. The central axis of the first transmission shaft 210 coincides with the central axis of the first transmission wheel 220. For example, the first transmission wheel 220 and the first transmission shaft 210 may be connected by a key or interference fit to ensure that the first transmission shaft 210 can synchronously drive the first transmission wheel 220 to rotate when it rotates.

[0049] The first conveyor belt 230 can form a transmission engagement (including but not limited to friction engagement or meshing) with all the first conveyor wheels 220 located on the first side of all the first conveyor shafts 210. The second conveyor belt 230 can form a transmission engagement with all the first conveyor wheels 220 located on the second side of all the first conveyor shafts 210. Thus, the upper surfaces of the two conveyor belts 230 are at the same horizontal plane, jointly supporting the foam pad stack 1500. Simultaneously, a certain gap is reserved between the two conveyor belts 230, thereby forming a blocking movement channel 2301 for the first blocking assembly 300 to move upwards. When the first blocking assembly 300 moves upwards, the foam pad stack 1500 rises from the blocking movement channel 2301 to a position higher than the upper surface of the conveyor belts 230, thereby blocking the foam pad stack 1500 located on the conveyor belts 230.

[0050] The first transmission driver 240 is mounted on the support base 100 and is drive-connected to one of the first transmission shafts 210. For example, the first transmission driver 240 can be a power source that outputs rotational motion, such as a motor. The output shaft of the first transmission driver 240 is coaxially fixed with the first transmission shaft 210, so that when the first transmission driver 240 is working, it can drive the first transmission shaft 210 to rotate, thereby driving the conveyor belt 230 to rotate and transport the foam pad stack 1500. Those skilled in the art can also set a tensioning device, such as a tensioning wheel, at a corresponding position on the support base 100 to adjust the tension of the conveyor belt 230. The outer diameter of the first transmission wheel 220 can also be adapted to the width of the conveyor belt 230, thereby preventing the conveyor belt 230 from shifting along the axial direction of the first transmission wheel 220 during movement.

[0051] Based on the above structural design, stable conveying of the foam pad stack 1500 can be achieved, and the obstruction movement channel 2301 can be formed between the two conveyor belt 230 supports, so that the first obstruction component 300 does not need to occupy horizontal space, thus reducing the overall size of the equipment. Furthermore, when the first obstruction component 300 forms a movement obstruction to the foam pad stack 1500, the conveyor belt 230 can continue to operate continuously without frequent starting and stopping of the first conveyor drive 240, and without causing wear and tear on the conveyor belt 230 due to obstruction. This improves the service life of the first conveyor component 200 and increases the conveying efficiency of the foam pad stack 1500, which is beneficial for further improving the packaging efficiency of the foam pad 1510.

[0052] In one or more embodiments, refer to Figure 1 , Figure 3 as well as Figure 5 As shown, the foam pad 1510 packaging device may further include a first feeding assembly 700. The first feeding assembly 700 may include a first feeding base 710, a feeding baffle 720, a first feeding conveying unit 730, and a pressure roller 740. The first feeding base 710 is used to place the pad 1700. The feeding baffle 720 is installed on the first feeding base 710 and cooperates with the first feeding base 710 to form a feeding guide channel 7201 through which a single layer of pad 1700 passes. The first feeding conveying unit 730 is installed on the first feeding base 710. When the first feeding conveying unit 730 is working, it drives the pad 1700 through the feeding guide channel 7201 and conveys it to the second end of the first conveying assembly 200. The pressure roller 740 is rotatably connected to the first feeding base 710 and forms pressure contact with the pad 1700 passing through the feeding guide channel 7201.

[0053] In this embodiment of the application, the first feeding component 700 is used to convey the bottom pad 1700 required for packaging the foam pad stack 1500 to the second end of the first conveying component 200, that is, automatically convey the bottom pad 1700 to the second end of the first conveying component 200, and so that during the process of conveying the pad 1700 along the second end of the first conveying component 200 to the first end, the stacked foam pad stack 1500 is transferred to the pad 1700 by the pad stack clamping unit 620.

[0054] The first feeding assembly 700 may include a first feeding base 710, a feeding baffle 720, a first feeding conveying unit 730, and a pressure roller 740. The first feeding base 710 is used to place the pad 1700. For example, the pad 1700 can be stacked and placed on the first feeding base 710. The feeding baffle 720 can be installed obliquely on the first feeding base 710, wherein a feeding guide channel 7201 can be formed between the bottom of the feeding baffle 720 and the first feeding base 710. The feeding guide channel 7201 allows only a single layer of pad 1700 to pass through. That is, the height of the feeding guide channel 7201 is greater than or equal to the thickness of a single layer of pad 1700, and less than the thickness of two layers of pad 1700 stacked together.

[0055] The first unloading conveyor unit 730 is mounted on the first unloading base 710 and located at the bottom of the stacked pads 1700. When the first unloading conveyor unit 730 is working, it can convey the stacked pads 1700 towards the second end of the first conveying assembly 200. However, due to the height limitation of the unloading guide channel 7201, only the bottommost pad 1700 of the stacked pads can be conveyed by the first unloading conveyor unit 730 through the unloading guide channel 7201. Other pads 1700 remain stationary or undergo only a small displacement due to the obstruction of the baffle. Thus, the stacked pads 1700 can be unloaded one by one. In some embodiments, the first unloading conveyor unit 730 can be implemented by a combination of a conveyor belt 230 and conveyor wheels, and can be powered by a motor or other driving components; no specific limitations are made here.

[0056] The pressure roller 740 is rotatably connected to the first unloading base 710 and forms a pressure contact with the pad 1700 passing through the unloading guide channel 7201. The setting of the pressure roller 740 allows the pad 1700 located on the first unloading transmission unit to be smoothly conveyed to the first transmission component 200, avoiding the pad 1700 from moving onto the first transmission component 200 without the limiting action and causing positional deviation, which would reduce the packaging quality of the foam pad 1510.

[0057] Based on the above structural design, the bottom pad 1700 of the foam pad 1510 can be automatically unloaded, and the packing rhythm can be adapted to the conveying speed of the first unloading conveying unit 730, which greatly improves the packing efficiency of the foam pad 1510 without the need for manual intervention.

[0058] In one or more embodiments, refer to Figure 5As shown, the first unloading assembly 700 may further include two first unloading limiting members 750. The two first unloading limiting members 750 are distributed at intervals on the first unloading base 710 and cooperate to form an unloading limiting channel 7501 distributed along the length direction of the first unloading conveying unit 730, so as to limit the movement trajectory of the pad 1700 through the unloading limiting channel 7501.

[0059] In this embodiment, the first unloading limiting member 750 can be an elongated structure, and its length direction is parallel to the length direction (also known as the conveying direction) of the first unloading conveying unit 730. For example, two first unloading limiting members 750 can be spaced apart on the first unloading base 710 and detachably connected to it. The distance between the two first unloading limiting members 750 is greater than the width of the pad 1700. This allows for the formation of an unloading limiting channel 7501 distributed along the length direction of the first unloading conveying unit 730, thereby limiting the movement trajectory of the pad 1700 through the unloading limiting channel 7501.

[0060] Based on the above structural design, under the limiting action of the feeding limiting channel 7501, the pad 1700 will not undergo large displacement or even directional reversal, which facilitates the blocking and positioning of the foam pad stack 1500 by the first blocking component 300, and improves the positioning accuracy of the foam pad stack 1500 by the combination of the first telescopic positioning component 400 and the first blocking component 300.

[0061] In one or more embodiments, refer to Figure 1 , Figure 3 as well as Figure 6As shown, the foam pad 1510 packaging device further includes a second feeding assembly 800 and a feeding transfer assembly 900, wherein the second feeding assembly 800 and the first feeding assembly 700 have the same structure. The feeding transfer assembly 900 may include a feeding conveying base 910, a second feeding conveying unit 920, a second feeding blocking unit 930, two second telescopic positioning units 940, and a pad transfer unit 950. The second feeding conveying unit 920 is mounted on the feeding conveying base 910, and the first end of the second feeding conveying unit 920 is in transmission cooperation with the second feeding assembly 800. The second feeding blocking unit 930 is mounted on the feeding conveying base 910 and is located at the second end of the second feeding conveying unit 920. When the second feeding blocking unit 930 moves upward, it blocks the pad 1700 on the second feeding conveying unit 920. Two second telescopic positioning units 940 are distributed on both sides of the second unloading conveying unit 920 and are mounted on the unloading conveying base 910. When the two second telescopic positioning units 940 extend relative to each other, they position the pad 1700, which is blocked by the second unloading blocking unit 930. The pad transfer unit 950 is located above the second telescopic positioning units 940 and is used to transfer the pad 1700 to the top of the foam pad stack 1500 filled with sponge blocks 1600.

[0062] In this embodiment, the second feeding component 800 is used to convey the top pad 1700 required for packaging the foam pad stack 1500 to the feeding and transfer component 900. Specifically, it automatically transfers the top pad 1700 to the feeding and transfer component 900, and then transfers the pad 1700 to the top of the foam pad stack 1500 filled with sponge blocks 1600. The second feeding component 800 can have the same structure as the first feeding component 700, thereby enabling automatic feeding of the top pad 1700 of the foam pad 1510.

[0063] The material unloading and transfer assembly 900 may include an unloading conveying base 910, a second unloading conveying unit 920, a second unloading blocking unit 930, two second telescopic positioning units 940, and a pad transfer unit 950. The unloading conveying base 910 provides structural support for components such as the second unloading conveying unit 920, the second unloading blocking unit 930, and the two second telescopic positioning units 940. The second unloading conveying unit 920 is used to transfer the pad 1700 at the bottom. When the second unloading conveying unit 920 is operating, the pad 1700 located on the second unloading assembly 900 can be transferred from the first end of the second unloading conveying unit 920 to the second end of the second unloading conveying unit 920.

[0064] The second unloading conveying unit 920, the second unloading blocking unit 930, and the two second telescopic positioning units 940 are respectively mounted on the unloading conveying base 910. The second unloading blocking unit 930 is located at the second end of the second unloading conveying unit 920 and is used to block the pad 1700 located on the second unloading conveying unit 920. The second unloading blocking unit 930 can move up and down during operation. When the second unloading blocking unit 930 is moving upward or in a raised state, the second unloading blocking unit 930 limits the pad 1700 located on the second unloading conveying unit 920 along the conveying direction of the second unloading conveying unit 920.

[0065] Two second telescopic positioning units 940 are distributed on both sides of the second unloading conveying unit 920, specifically on both sides of the second unloading conveying unit 920 along its width. The second telescopic positioning units 940 perform telescopic movements during operation. When the two second telescopic positioning units 940 extend in opposite directions, they respectively abut against both sides of the pad 1700 blocked by the second unloading blocking unit 930, thereby enabling three-sided positioning of the pad 1700. In other words, the position of each pad 1700 after passing through the second unloading blocking unit 930 and the two second telescopic positioning units 940 is consistent.

[0066] The pad transfer unit 950 is located above the second unloading and conveying unit 920, and is used to transfer the positioned pad 1700 to the top of the foam pad stack 1500 filled with sponge blocks 1600.

[0067] In some embodiments, the structure of the second feeding conveying unit 920 can be consistent with the structure of the first conveying component 200, the structure of the second feeding blocking unit 930 can be consistent with the structure of the first blocking component 300, and the structure of the second telescopic positioning unit 940 can be consistent with the structure of the first telescopic positioning component 400.

[0068] Based on the above structural design, the top pad 1700 of the foam pad 1510 can be automatically unloaded. The pad 1700, conveyed from the second unloading conveying unit 920, can be positioned on three sides by the extension of the second unloading blocking unit 930 and the second telescopic positioning unit 940. Finally, the positioned pad 1700 is transferred to the top of the foam pad stack 1500 filled with sponge blocks 1600 via the pad transfer unit 950, thereby greatly improving the packaging efficiency of the foam pad 1510.

[0069] In one or more embodiments, refer to Figure 6 and Figure 7 As shown, the pad transfer unit 950 may include a transfer frame 951, a transfer linear driver 952, a transfer lifter 953, and at least one transfer suction cup 954. The transfer frame 951 is located above the second telescopic positioning unit 940, and the transfer linear driver 952 is mounted on the transfer frame 951. The transfer lifter 953 is drively connected to the transfer linear driver 952, and when the transfer linear driver 952 is working, it drives the transfer lifter 953 to perform reciprocating linear motion in the horizontal direction. At least one transfer suction cup 954 is mounted on the output shaft of the transfer lifter 953, and the transfer suction cup 954 is used to adsorb the pad 1700. When the transfer lifter 953 is working, it moves the transfer suction cup 954 to perform lifting and lowering motion.

[0070] In this embodiment, the transfer frame 951 is located above the second telescopic positioning unit 940 and provides structural support for other components of the pad transfer unit 950 besides the transfer frame 951. For example, the transfer linear actuator 952 can be mounted on the transfer frame 951. The transfer linear actuator 952 can be used to output linear motion. For example, when the transfer lifter 953 is connected to the transfer linear actuator 952, the transfer linear actuator 952 can drive the transfer lifter 953 to perform reciprocating linear motion on a horizontal surface when it is working, thereby driving the transfer lifter 953 to perform linear motion towards or away from the foam pad stack 1500. The transfer linear actuator 952 may include, but is not limited to, devices such as a transverse cylinder or an electric cylinder, and the transfer lifter 953 may include, but is not limited to, devices such as a cylinder or an electric telescopic rod.

[0071] At least one of the transfer suction cups 954 is mounted on the output shaft of the transfer lifter 953, which can drive the transfer suction cup 954 to perform lifting and lowering movements when the transfer lifter 953 is working. The transfer suction cup 954 is used to adsorb the pad 1700, thereby completing the transfer of the pad 1700.

[0072] During the process of the pad transfer unit 950 transferring the pad 1700, the transfer linear actuator 952 drives the suction cup to move in a straight line towards the pad 1700 blocked by the second feeding blocking unit 930, until the suction cup moves directly above the pad 1700 blocked by the second feeding blocking unit 930. Then, the transfer lifting device 953 actuates, driving the transfer suction cup 954 to descend. The transfer suction cup 954 descends to a position where it contacts the surface of the pad 1700, allowing the transfer suction cup 954 to firmly adhere to the pad 1700. Then, the transfer lifting device 953 retracts, driving the transfer suction cup 954 to rise. Next, the transfer linear actuator 952 drives the suction cup to move towards the foam pad stack 1500 filled with sponge blocks 1600, until the suction cup moves directly above the foam pad stack 1500 filled with sponge blocks 1600. The transfer lift 953 actuates, causing the transfer suction cup 954 to descend. The pad 1700 descends to a position where it contacts the foam pad stack 1500, causing the transfer suction cup 954 to release its grip on the pad 1700. This completes the placement of the pad 1700 on the foam pad stack 1500. Finally, the transfer lift 953 retracts, causing the transfer suction cup 954 to rise. This causes the transfer linear actuator 952 to operate, moving the suction cup in a straight line towards the pad 1700 that was blocked by the second unloading blocking unit 930. This initiates the transfer of the next pad 1700.

[0073] Based on the above structural design, the top pad 1700 of the foam pad 1510 can be automatically unloaded, and the packing rhythm can be adapted to the conveying speed of the second unloading conveying unit 920, which greatly improves the packing efficiency of the foam pad 1510 without the need for manual intervention.

[0074] One or more implementation methods, refer to Figure 1 , Figure 3 . Figure 8 as well as Figure 9As shown, the foam pad 1510 packaging equipment may further include a foam stacking base 1000, a stacking conveying assembly 1100, and a stacking receiving assembly 1200. The stacking conveying assembly 1100 is installed on the foam stacking base 1000. When the stacking conveying assembly 1100 is working, it conveys the foam pad stack 1500 from the first end of the stacking conveying assembly 1100 to the second end of the stacking conveying assembly 1100. The stacking receiving assembly 1200 is located at the first end of the stacking conveying assembly 1100. When the stacking receiving assembly 1200 is in the rising state, the top of the stacking receiving assembly 1200 receives the foam pad stack 1500. When the stacking receiving assembly 1200 is lowered to the lowest position, the top of the stacking receiving assembly 1200 is lower than the conveying surface of the stacking conveying assembly 1100, so that the foam pad stack 1500 located on the stacking receiving assembly 1200 is conveyed by the stacking conveying assembly 1100 to the clamping area of ​​the pad clamping unit 620.

[0075] In this embodiment, the foam stacking base 1000 provides structural support for the stacking conveying assembly 1100 and the stacking receiving assembly 1200. When the stacking conveying assembly 1100 is in operation, it conveys the foam pad stack 1500 from a first end to a second end of the stacking conveying assembly 1100. For example, the structure of the stacking conveying assembly 1100 can be consistent with the structure of the first conveying assembly 200.

[0076] The stacking receiving component 1200 is located at the first end of the stacking conveying component 1100. That is, the foam pad stack 1500 is conveyed from the pad receiving component to the first end of the stacking conveying component 1100. Then, through the operation of the stacking conveying component 1100, the foam pad stack 1500 located at the first end of the stacking conveying component 1100 is conveyed to the second end of the stacking conveying component 1100 until it reaches the clamping area of ​​the pad clamping unit 620 at the second end of the stacking conveying component 1100. Then, through the operation of the pad clamping unit 620, the foam pad stack 1500 located on the stacking conveying component 1100 is transferred.

[0077] In some embodiments, when the stacking receiving assembly 1200 is in an upward state, the top of the stacking receiving assembly 1200 receives the foam pad stack 1500. The top of the stacking receiving assembly 1200 can gradually descend, thereby stacking the foam pads 1510 one by one to form the foam pad stack 1500. When the stacking receiving assembly 1200 descends to its lowest position, the top of the stacking receiving assembly 1200 is lower than the conveying surface of the stacking conveying assembly 1100, and the foam pad stack 1500 located on the stacking receiving assembly 1200 is conveyed by the stacking conveying assembly 1100 to the clamping area of ​​the pad clamping unit 620.

[0078] Based on the above structural design, the foam pad 1510 can be automatically stacked, further improving the packaging efficiency of the foam pad 1510.

[0079] In one or more embodiments, refer to Figure 8 and Figure 9 As shown, the stacking receiving assembly 1200 may include a limiting platform 1210, a stacking limiting member 1220, at least two stacking positioning units 1230, a stacking lifter 1240, and a stacking support 1250. The limiting platform 1210 is mounted on the foam stacking base 1000 and located above the stacking conveying assembly 1100. The limiting platform 1210 and the stacking conveying assembly 1100 cooperate to form a stacking guide channel 12101 for the passage of multiple stacked foam pads 1500. For example, a limiting groove may be provided on the limiting platform 1210 to form a stacking space for the foam pads 1510 to be stacked.

[0080] The stacking limiting member 1220 is located at the first end of the stacking conveying assembly 1100 and is fixedly connected to the foam stacking base 1000. At least two stacking positioning units 1230 are distributed on the limiting platform 1210 and cooperate with the stacking limiting member 1220 to form at least three-sided limiting of the foam pad stack 1500. For example, three stacking positioning units 1230 can be provided, and the three stacking positioning units 1230 can be located on different sides of the limiting groove, so that they can cooperate with the stacking limiting member 1220 to form four-sided limiting of the foam pad stack 1500, thereby improving the stacking neatness of the foam pad 1510. The structure of the stacking positioning unit 1230 can be consistent with the structure of the first telescopic positioning assembly 400.

[0081] The stacking lift 1240 is mounted on the foam stacking base 1000, and the stacking support 1250 is drively connected to the output shaft of the stacking lift 1240. The stacking lift 1240 may include, but is not limited to, devices such as cylinders. When the stacking lift 1240 raises the stacking support 1250 to its highest position, the stacking support 1250 is higher than the conveying surface of the stacking conveying assembly 1100, allowing the foam pads 1510 to be stacked on the stacking support 1250. For example, the stacking lift 1240 can descend in successive heights, each time descending by the thickness of one layer of foam pad 1510. This allows for the storage of stacking space for the next layer of foam pads 1510 after each layer of foam pads 1510 has been received on the stacking support 1250. Furthermore, after each layer of foam pad 1510 is stacked, each stacking positioning unit 1230 moves relative to the foam pad 1510 to abut against it, thereby adjusting the stacking position of each layer of foam pad 1510 and improving the stacking neatness of the foam pad stack 1500.

[0082] When the stacker lift 1240 lowers the stacker support 1250 to its lowest position, and the stacker support 1250 is lower than the conveying surface of the stacker conveying assembly 1100, the stacker conveying assembly 1100 receives the foam pad stack 1500 and conveys it.

[0083] Based on the above structural design, the automatic stacking of the foam pads 1510 can be achieved, and the stacking neatness of the foam pad stacks 1500 can be greatly improved, thereby ensuring packaging efficiency and packaging quality.

[0084] In one or more embodiments, refer to Figure 1 and Figure 3 As shown, the foam pad 1510 packaging equipment may further include a negative pressure conveying device 1300, which is located above the stacking receiving assembly 1200. The distance between the stacking positioning unit 1230 and the bottom of the negative pressure conveying device 1300 is less than the thickness of a single layer of the foam pad 1510, so that the single layer of foam pad 1510 conveyed from the bottom of the negative pressure conveying device 1300 is limited to stacking on the stacking support 1250.

[0085] In this embodiment, the negative pressure conveying device 1300 is a device based on the principle of negative pressure adsorption, which uses gas pressure difference to fix materials to the surface of the negative pressure conveying device 1300, and can realize material conveying from the bottom. The negative pressure conveying device 1300 is located above the stacking receiving assembly 1200, and is used to convey the completed single-layer foam pads 1510 one by one.

[0086] The negative pressure conveying device 1300 is located above the stacking receiving assembly 1200, wherein the distance between the bottom of the stacking positioning unit 1230 and the negative pressure conveying device 1300 is less than the thickness of a single layer of the foam pad 1510. Therefore, when the negative pressure conveying device 1300 passes the stacking receiving assembly, the stacking positioning unit 1230 can release the negative pressure conveying device 1300 from the foam pad 1510, causing the foam pad 1510 to fall onto the stacking support 1250. The stacking lifter 1240 can then lower the stacking support 1250. For example, it can lower the support by the height of one foam pad 1510 at a time, thus allowing multiple layers of the foam pad 1510 to be stacked on the stacking support 1250.

[0087] Based on the above structural design, the foam pad 1510 can be stably adsorbed at the bottom of the negative pressure conveying device 1300, facilitating the stacking of the foam pad 1510 on the stacking support 1250. When the preset number of layers is reached, the stacking support 1250 is driven down to its lowest position, and the stacking conveying component 1100 receives and conveys the preset number of foam pad stacks 1500. This enables automatic stacking of the foam pad 1510 and automatic transfer of the stacks 1500 after reaching the preset number of layers, further improving the packaging efficiency of the foam pad 1510.

[0088] In one or more embodiments, refer to Figure 1 and Figure 3 As shown, the foam pad 1510 packaging equipment may further include a strapping machine 1400, which is located at the end of the transfer frame 951 away from the sponge robot assembly 500. When the strapping machine 1400 is working, it straps the foam pad stack 1500 on which the top pad 1700 is placed. Thus, the strapping machine 1400 can automatically strap the foam pad stack 1500, thereby completing the packaging process of the foam pad 1510.

[0089] Based on the above structural design, the automatic transfer of the foam pad stack 1500, the automatic placement of the bottom pad 1700, the automatic placement of the sponge block 1600 into the groove 1501 of the positioned foam pad stack 1500, the automatic placement of the top pad 1700, and the automatic strapping can be realized, thereby realizing a fully automated packaging process for the foam pad 1510 and greatly improving the packaging efficiency of the foam pad 1510.

[0090] In some implementations, conveying components, blocking components, or positioning components may be added depending on the location of different packaging processes, and no further limitations are made here.

[0091] In summary, this application discloses a foam pad 1510 packaging device. The device may include a support base 100, a first conveying component 200, a first blocking component 300, two first telescopic positioning components 400, and a sponge robot component 500. The first conveying component 200 is mounted on the support base 100, and the first blocking component 300 is mounted on the support base 100 and located at the first end of the first conveying component 200. When the first blocking component 300 moves upward, it blocks the foam pad stack 1500 on the first conveying component 200. The two first telescopic positioning components 400 are distributed on both sides of the first conveying component 200 and mounted on the support base 100. When the two first telescopic positioning components 400 extend relative to each other, they position the foam pad stack 1500 blocked by the first blocking component 300. The sponge robot component 500 is located at the first end of the first conveying component 200 and is used to grasp sponge blocks 1600 and place them into the grooves 1501 of the positioned foam pad stack 1500. Therefore, the foam pad stack 1500 conveyed from the first conveying component 200 can be limited on three sides by the extension cooperation of the first blocking component 300 and the first telescopic positioning component 400. This allows for precise positioning of the groove 1501 in the foam pad stack 1500. Finally, the sponge robot component 500 inserts the sponge block 1600 into the foam pad stack 1500, thereby greatly improving the packaging efficiency of the foam pad 1510.
