Description

Technical Field

[0001] This invention relates to the field of detergent production equipment, and particularly to a detergent block and stain-removing ball embedded assembly. Background Technology

[0002] With the improvement of living standards, the market share of dishwashers is also increasing year by year. As one of the consumables for dishwashers, dishwashing tablets have a very promising commercial prospect. In order to improve the cleaning ability and product competitiveness of dishwashing tablets, some manufacturers embed cleaning balls into the surface of ordinary dishwashing tablets, such as the design patent CN307808209S "Dishwashing Tablets". The cleaning balls contain enhanced cleaning ingredients and together with the dishwashing tablets form a composite dishwashing tablet, which can effectively remove stubborn stains.

[0003] Currently, composite detergent blocks are manufactured through multiple pressing processes, which requires the design of complex molds and the use of specialized composite pressing machines. This results in high equipment investment costs, and the specialized composite pressing machines can only produce composite detergent blocks, leading to persistently high production costs for composite detergent blocks. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the above-mentioned related technologies and proposes a detergent block cleaning ball embedded assembly that can be adapted and installed on a conventional detergent block production line without the need for a special composite tablet press.

[0005] According to a first aspect of the present invention, a detergent block and stain-removing ball embedded assembly comprises: A first conveyor is provided with a first conveyor line for sequentially conveying detergent blocks. The first conveyor line has a conveying direction arranged in a front-back direction. The surface of the detergent blocks is provided with embedded holes. A positioning mechanism is provided on the first conveyor line. The positioning mechanism is configured to limit multiple detergent blocks to a preset position on the first conveyor line. The second conveyor is provided with a second conveying line for conveying decontamination balls. The second conveying line is provided with multiple conveying channels and multiple discharge ports. The multiple discharge ports are spaced apart in the front-back direction. A docking platform is located on the left or right side of the first conveyor, between the first conveyor and the second conveyor. The docking platform is equipped with a linear drive device, which drives a movable plate to reciprocate in the front-back direction, so that the movable plate has a first station and a second station. The surface of the movable plate is provided with multiple positioning grooves, each of which can only accommodate one cleaning ball. When the movable plate is in the first station, the multiple positioning grooves are respectively docked with the multiple discharge ports of the multi-channel conveyor. When the movable plate is in the second station, the multiple positioning grooves are respectively aligned with the embedding holes of the multiple cleaning blocks that are confined to the first conveyor line in the front-back direction. A two-dimensional clamping mechanism is provided with multiple clamping parts. Each clamping part has a first moving path and a second moving path under the drive of the two-dimensional clamping mechanism. The first moving path is arranged in the vertical direction, and the second moving path is arranged in the horizontal direction. The multiple clamping parts are aligned one by one with the holes of the multiple washing blocks that are limited on the first conveying line in the front-back direction.

[0006] The detergent block cleaning ball embedding assembly according to an embodiment of the present invention has at least the following beneficial effects: the first conveyor is a conventional linear conveyor belt. When it is necessary to produce composite detergent blocks with cleaning balls, the workpiece it conveys is a detergent block with embedded holes. When it is not necessary to produce composite detergent blocks with cleaning balls, the workpiece it conveys is an ordinary detergent block. During operation, the positioning mechanism limits multiple detergent blocks to a preset position on the first conveyor line in a sequential arrangement, thereby fixing the position of each embedded hole. When the second conveyor conveys all the cleaning balls into the multiple positioning grooves of the movable plate, the linear drive device drives the movable plate to switch from the first working position state to the second working position state. The two-dimensional clamping mechanism separates the cleaning balls in the positioning groove from those in the multi-channel conveying system. Then, multiple clamping parts of the two-dimensional clamping mechanism simultaneously clamp and transfer the cleaning balls in the positioning groove to the corresponding holes in the cleaning block to form a composite cleaning block. Compared with existing technologies, this technology can be adapted to conventional cleaning block production lines. Therefore, by using or not using the embedding assembly, it can selectively meet the processing and production needs of different types of cleaning blocks, thus eliminating the need for a dedicated composite tablet press. Furthermore, it can produce several composite cleaning blocks at a time, improving production efficiency and significantly reducing the production cost of composite cleaning blocks, which is conducive to the widespread adoption of composite cleaning blocks.

[0007] According to some embodiments of the present invention, the second conveyor includes a vibratory feeder, a diversion channel, and the multi-channel conveying system. The vibratory feeder is provided with a discharge channel, and the multi-channel conveying system is connected to the discharge channel through the diversion channel.

[0008] According to some embodiments of the present invention, there is a gap of <1.5mm between the multi-channel conveying channel and the diversion channel, and a debris collection channel is provided below the gap.

[0009] According to some embodiments of the present invention, a vibration device is provided at the bottom of the multi-channel conveying system, the vibration device being used to accelerate the flow of the cleaning balls in the multi-channel conveying system.

[0010] According to some embodiments of the present invention, the docking platform is provided with a plurality of photoelectric sensors, and the detection direction of each photoelectric sensor is directed toward the position of the corresponding positioning groove when it is in the first working position.

[0011] According to some embodiments of the present invention, the docking platform is provided with a plurality of air blowing pipes, and the air blowing direction of each air blowing pipe is directed toward the position of the corresponding positioning groove when it is in the second working position.

[0012] According to some embodiments of the present invention, the two-dimensional clamping mechanism includes a left-right moving device and a right-up lifting device. The left-right moving device is driven and connected to a first mounting plate in the left-right direction. The right-up lifting device is mounted on the first mounting plate and driven and connected to a second mounting plate in the up-down direction. A plurality of clamping parts are mounted on the second mounting plate.

[0013] According to some embodiments of the present invention, the two-dimensional clamping mechanism is further provided with a plurality of dispensing valves, the dispensing valves being further away from the second conveyor relative to the clamping part, and the plurality of dispensing valves having an initial position that is aligned one-to-one with the recesses of the plurality of cleaning blocks defined on the first conveyor line in the vertical direction.

[0014] According to some embodiments of the present invention, a first clearance space is provided between every two discharge ports, and each positioning groove is connected to a second clearance space. When the movable plate is in the second working position, the first clearance space and the second clearance space are used together to avoid the clamping part.

[0015] According to some embodiments of the present invention, the positioning mechanism includes a blocking unit and a pressing unit. The blocking unit is disposed downstream of the pressing unit on the first conveyor line. The blocking unit is movably connected to a baffle for blocking the washing block. The pressing unit is movably connected to a pressing block that moves in the left-right direction at the first conveyor line.

[0023] like Figure 1 As shown, the present invention discloses a detergent block 600 embedding assembly, which includes a base frame 100, a first conveyor 200, a second conveyor 300, a docking platform 400, and a two-dimensional clamping mechanism 500. The base frame 100 provides an installation reference for the first conveyor 200, the second conveyor 300, the docking platform 400, and the two-dimensional clamping mechanism 500. The base frame 100 has configurations related to pneumatic and electric drives. The first conveyor 200 is used to convey detergent blocks 600, the second conveyor 300 is used to convey cleaning balls 700, the docking platform 400 is used to dock the second conveyor 300 with the first conveyor 200, and the two-dimensional clamping mechanism 500 is used to clamp and transfer the cleaning balls 700 on the docking platform 400 and embed them into the holes 610 of the detergent blocks 600 on the first conveyor 200.

[0024] This invention aims to solve the technical problems of existing composite detergent block production, which relies on dedicated composite tablet presses, resulting in high modification costs and low production efficiency. By adapting to conventional detergent block production lines, it achieves precise batch embedding of cleaning balls 700, while reducing modification costs and enhancing product market competitiveness. The following detailed description of the various components and connections of this invention, in conjunction with specific embodiments, provides a detailed explanation.

[0025] like Figure 2As shown, the first conveyor 200 can serve as the conveying section of a conventional detergent block production line. It includes a frame 210, a first conveyor line 220, and a positioning mechanism. The frame 210 is constructed from aluminum alloy profiles, offering both lightweight and high strength advantages. Its height can be adjusted according to the standard production line height to meet the installation requirements of different production scenarios. The first conveyor line 220 employs a belt conveyor structure, specifically using a PU conveyor belt. This belt has an anti-slip texture on its surface to effectively prevent the detergent blocks 600 from slipping during transport. Its conveying direction is set along the front-to-back direction; in this embodiment, the front direction is the downstream conveying direction, and the rear direction is the upstream conveying direction. The conveying speed of the conveyor belt can be adjusted via a variable frequency motor to adapt to different production cycle requirements.

[0026] The surface of the first conveyor line 220 is provided with two rows of limiting plates 240. Each row of limiting plates 240 is fixedly connected to the frame 210 via a connecting block, ensuring that the two rows of limiting plates 240 do not rotate with the first conveyor line 220. The two rows of limiting plates 240 together form a feeding channel 241 slightly larger than the width of a single washing block 600, to accommodate the sequential feeding of multiple washing blocks 600. Since the washing blocks 600 come in various sizes, the setting of the limiting plates 240 allows for the sequential feeding of washing blocks 600 of different sizes without altering the structure of the first conveyor line 220, simply by adjusting the spacing between the two rows of limiting plates 240.

[0027] It should be noted that, since this embodiment requires the production of composite detergent blocks, all detergent blocks 600 conveyed on the first conveyor line 220 have embedded holes 610 on their surfaces. The size of the embedded holes 610 is adapted to the size of the cleaning balls 700. Because the detergent block cleaning ball embedding assembly is configured on the detergent block production line, and some detergent block production lines have a water-soluble film packaging machine downstream of the embedding assembly, the aperture of the embedded holes 610 can be 0.2mm to 0.5mm larger than the diameter of the cleaning balls 700. The two are designed with an overfit to facilitate the embedding of the cleaning balls 700. Since the composite detergent blocks are packaged immediately after production, there is no possibility of the cleaning balls 700 falling out of the embedded holes 610. Once the composite detergent block is packaged with a water-soluble film and heat-shrinked by a heat-shrinking machine, the cleaning balls 700 and the detergent block 600 will be tightly bonded together under the shrinkage force of the water-soluble film. When in use, because the packaging material of the composite detergent tablets is a water-soluble film, users do not need to open the outer packaging of the composite detergent tablets before putting them into the dishwasher, making it very convenient to use.

[0028] Compared to a dedicated composite tablet press, the detergent block 600 with embedded holes 610 can be processed using a regular tablet press, as can the cleaning ball 700. The mold cost of a regular tablet press is very low, and the tablet press used is also a very mature processing equipment. Therefore, the company only needs to spend a small amount of mold opening cost to complete the processing of the detergent block 600 with embedded holes 610 and the cleaning ball 700. At this time, the cost of the product is mainly concentrated on the raw materials.

[0029] Furthermore, a positioning mechanism is installed on the first conveyor line 220. Its core function is to limit multiple washing blocks 600 to a preset position on the first conveyor line 220, ensuring that the insertion hole 610 of each washing block 600 can be precisely aligned with the subsequent clamping part 540. The positioning mechanism includes a blocking unit 231, a pressing unit 232, and a counter (not shown in the attached figure). The counter is located upstream of the pressing unit 232 on the first conveyor line 220, specifically installed on one side of the limiting plate 240. The counter uses an infrared detection sensor, and its detection direction is towards the conveying surface of the feeding channel 241, which can detect the number of washing blocks 600 passing through in real time. When the counter detects a specified number of washing blocks 600, it sends a signal to the control system, and the control system sequentially activates the blocking unit 231 and the pressing unit 232.

[0030] The blocking unit 231 is positioned downstream of the pressing unit 232 on the first conveyor line 220. It includes a cylinder mounting base, a blocking cylinder 2311, and a baffle 2312. The cylinder mounting base is fixedly connected to a vertical frame 510 located above the first conveyor line 220. The blocking cylinder 2311 is vertically mounted on the cylinder mounting base, and the baffle 2312 is fixed to the top of the piston rod of the blocking cylinder 2311. Upon receiving a signal from the counter, the piston rod of the blocking cylinder 2311 extends, causing the baffle 2312 to move downwards to block the feeding channel 241, thereby preventing the subsequent washing blocks 600 from continuing to be conveyed forward.

[0031] After the blocking unit 231 has been activated for a period of time, until the washing blocks 600 on the feeding channel 241 are pressed together by the baffle 2312 and the first conveyor line 220, the pressing unit 232 will start. The pressing unit 232 includes a pressing cylinder 2321 and a pressing block 2322 located on one side of the first conveyor line 220. The pressing unit 232 is located away from the second conveyor 300. The pressing cylinder 2321 is horizontally mounted on the frame 210, and its piston rod extends in the left and right direction. The pressing block 2322 is fixed to the end of the piston rod. The length of the pressing block 2322 needs to be determined according to the number of washing blocks 600 that need to be pressed. The more washing blocks 600 that need to be pressed, the longer the pressing block 2322 will be. The pressing block 2322 can be a polyurethane block to reduce the risk of the washing blocks 600 being crushed. One of the limiting plates 240 is provided with a clearance area to avoid the pressing unit 232, so that the pressing block 2322 can press and position the multiple washing blocks 600 located on the feeding channel 241 toward the other limiting plate 240, thereby limiting the position of the hole 610 of a specified number of washing blocks 600.

[0032] like Figure 3 and Figure 4 As shown, the core function of the second conveyor 300 is to convey the cleaning balls 700. It includes a vibrating plate 310, a diversion channel 320, a multi-channel conveying channel 330 and a vibration device 340. Specifically, it is located on the left side of the first conveyor 200, maintaining a certain distance from the first conveyor 200. This distance provides sufficient space for the installation of the docking platform 400. The vibratory feeder 310, serving as the feeding device for the cleaning balls 700, boasts advantages such as large capacity and stable feeding. The inner wall of the vibratory feeder 310 is equipped with a spiral feeding track, the width of which is adapted to the diameter of the cleaning balls 700. During operation, the vibratory feeder 310 uses a vibrating motor at its bottom to drive the hopper to vibrate, causing the cleaning balls 700 to gradually rise along the spiral track. During this rising process, a debris channel is provided on the vibratory feeder 310, located on the essential path of the cleaning balls 700. Debris generated during the vibration conveying of the cleaning balls 700 falls from this channel into the debris collection box below, preventing debris from mixing into the intact cleaning balls 700 and affecting subsequent embedding quality. The discharge channel of the vibratory feeder 310 connects to the diversion channel 320. A guide plate is located at the end of the discharge channel, guiding the cleaning balls 700 smoothly into the diversion channel 320.

[0033] The function of the diversion channel 320 is to divide the single-path cleaning balls 700 conveyed by the vibratory feeder 310 into multiple paths. It includes a pre-diversion area and a post-diversion area. Taking this embodiment as an example, the pre-diversion area has three pre-channels 321, while the post-diversion area has six post-channels 322. Every two post-channels 322 are connected to one pre-channel 321, ultimately achieving the goal of discharging six balls from one outlet of the vibratory feeder 310. The inner wall of the diversion channel 320 is smooth and polished to reduce the friction during the conveying of the cleaning balls 700.

[0034] The multi-channel conveying channel 330 connects to the discharge channel via a diversion channel 320. The multi-channel conveying channel 330 has the same number of channels as the downstream channel 322. The multi-channel conveying channel 330 is expanded to widen the distance between two adjacent discharge ports 331, thus providing a structural basis for subsequent separation and transfer. There is a gap 350 of less than 1.5 mm between the multi-channel conveying channel 330 and the diversion channel 320. Specifically, the gap 350 is about 0.8 mm in size. This gap 350 is much smaller than the diameter of the cleaning ball 700, which ensures that the complete cleaning ball 700 can pass through smoothly, while the debris generated during the conveying process will fall out from the gap 350. Below the gap 350, there is a debris collection channel 360. The debris collection channel 360 adopts a funnel-shaped structure. The opening size at the top covers the entire gap 350 area, and the bottom end is connected to the collection box. The tilt angle of the debris collection channel 360 is 60° to 70°, which can ensure that the debris can slide down quickly and avoid accumulation.

[0035] A vibration device 340 is installed at the bottom of the multi-channel conveying channel 330. The vibration device 340 uses a vibration motor with a vibration frequency of 50Hz to 60Hz. The vibration motor is fixed between the multi-channel conveying channel 330 and the base frame 100 by bolts. The vibration generated during its operation can accelerate the flow of the cleaning balls 700 in the multi-channel conveying channel 330, preventing the cleaning balls 700 from accumulating at the inlet position. The discharge ports 331 of the multi-channel conveying channel 330 are spaced apart in the front-to-back direction. The spacing between any two adjacent discharge ports 331 is consistent, and a first clearance space 332 is provided between every two discharge ports 331. The first clearance space 332 is of practical significance in subsequent clamping operations.

[0036] It should be further explained that, in this embodiment, the clamping unit 232 on the first conveyor line 220 can limit and fix 12 cleaning blocks 600 at a time, while the number of discharge ports 331 obtained from each second conveyor 300 is only 6. If the number of discharge ports 331 is set too much, it may cause poor diversion. Therefore, in order to meet the processing requirements, in this embodiment, the number of second conveyors 300 is set to two, and the two second conveyors 300 are arranged at intervals in the front-back direction. The two second conveyors 300 have a total of 12 discharge ports 331, so that 12 composite cleaning blocks can be processed at the same time in one processing step.

[0037] It is understood that in some other embodiments, the vibratory feeder 310 of the second conveyor 300 can be replaced with a conveyor belt, that is, the same structure as the first conveyor line 220 can be used. In this case, the first conveyor 200 is connected to a tablet press for producing detergent blocks 600, and the second conveyor 300 is connected to a tablet press for producing cleaning balls 700, and is not limited to the above embodiments.

[0038] like Figure 5 and Figure 6 As shown, the docking platform 400 is positioned between the first conveyor 200 and the second conveyor 300. Its core function is to facilitate the transition of the cleaning ball 700 from the second conveyor 300 to the insertion hole 610 of the cleaning block 600. The docking platform 400 includes a support frame 410, a linear drive device 420, a movable plate 430, a photoelectric sensor 440, and an air blowing pipe 450. The support frame 410 is fixedly connected to the base frame 100, and its height can be adjusted according to the height of the second conveyor 300 to ensure proper docking. The movable plate 430 is slidably connected to the support frame 410 in the front-back direction via a slider guide rail. The linear drive device 420, which can be a cylinder, is installed on the rear side of the support frame 410. The telescopic rod of the linear drive device 420 is fixedly connected to the movable plate 430 to achieve reciprocating movement of the movable plate 430 in the front-back direction. In this embodiment, the telescopic rod of the linear drive device 420 has two limiting lengths: one limiting length is the length when the telescopic rod is extended to its limit, and the other limiting length is the length when the telescopic rod is retracted to its limit, thereby giving the movable plate 430 a first station and a second station.

[0039] Of course, in some other embodiments, the linear drive device 420 may also be an electric push rod, which has higher movement stability and better positioning accuracy than cylinder drive, and can effectively avoid docking deviation caused by air pressure fluctuations.

[0040] The surface of the movable plate 430 is provided with a plurality of positioning grooves 431. The number of positioning grooves 431 is the same as the number of discharge ports 331 of the multi-channel conveying channel 330. In this embodiment, the number of positioning grooves 431 is 12. Each positioning groove 431 can only accommodate one cleaning ball 700. The size and shape of the positioning groove 431 are adapted to the size and shape of the cleaning ball 700. If the cross-sectional shape of the cleaning ball 700 is circular, then the shape of the positioning groove 431 is a rounded rectangle; if the cross-sectional shape of the cleaning ball 700 is rectangular, then the shape of the positioning groove 431 is also rectangular.

[0041] When the movable plate 430 is in the first working position, multiple positioning grooves 431 are aligned with multiple discharge ports 331 one by one, meaning that the cleaning balls 700 in the multi-channel conveying system 330 can enter the corresponding positioning groove 431 through the discharge port 331. Since each positioning groove 431 can only accommodate one cleaning ball 700, when the movable plate 430 is switched to the second working position by the linear drive device 420, the positioning grooves 431 can be separated from the cleaning balls 700 in the multi-channel conveying system 330, ensuring that only one cleaning ball 700 is transferred at each location. When the movable plate 430 is in the second working position, multiple positioning grooves 431 are aligned with the insertion holes 610 of multiple cleaning blocks 600 limited on the first conveyor line 220 in the front-to-back direction. At this time, the center of the positioning groove 431 and the center of the insertion hole 610 do not deviate from 0.2mm, providing precise positioning for subsequent clamping and transfer.

[0042] Photoelectric sensors 440 are mounted on the support frame 410 of the docking platform 400, located above the movable plate 430. Each photoelectric sensor 440's detection direction is towards the positioning groove 431 at its initial position. Using photoelectric sensors, the photoelectric sensors 440 detect the presence of cleaning balls 700 within the positioning groove 431. When the second conveyor 300 delivers cleaning balls 700 to the positioning groove 431, the photoelectric sensors 440 continuously monitor the material feeding status of each positioning groove 431. Only when all photoelectric sensors 440 detect the presence of cleaning balls 700 within the positioning groove 431 will the control system activate the linear drive device 420, driving the movable plate 430 to switch from the first position to the second position. If a positioning groove 431 fails to feed material into its designated position, the photoelectric sensor 440 sends a signal to the control system. The control system then suspends subsequent processes and issues an alarm. Workers must promptly investigate the cause of the malfunction to prevent product defects due to insufficient material.

[0043] Air blowing pipes 450 are mounted on the support frame 410 of the docking platform 400, located above the movable plate 430. The air blowing direction of each air blowing pipe 450 is towards the positioning groove 431 in its second working position. The air blowing pipes 450 are connected to a compressed air source with a working air pressure of 0.3MPa to 0.5MPa. During the clamping process of the two-dimensional clamping mechanism 500, some of the cleaning balls 700 may be crushed. If these fragments remain in the positioning groove 431, they will affect the smooth entry of subsequent cleaning balls 700, leading to a shortage of material. Therefore, after the two-dimensional clamping mechanism 500 completes one clamping and transfer cycle, the air blowing pipes 450 will blow air into the positioning groove 431 for 0.5s to 1s to remove any remaining fragments, ensuring the cleanliness of the positioning groove 431.

[0044] In addition, each positioning groove 431 is connected to a second clearance position 432. The first clearance position 332 and the second clearance position 432 are both rectangular groove structures. When the movable plate 430 is in the second working position, the positions of the first clearance position 332 and the second clearance position 432 correspond to each other. The first clearance position 332 and the second clearance position 432 are used together to avoid the clamping part 540 of the two-dimensional clamping mechanism 500, so that the gripper 542 of the clamping part 540 can enter the clearance position and clamp the cleaning ball 700 inward.

[0045] like Figure 2 and Figure 7 As shown, the core function of the two-dimensional clamping mechanism 500 is to clamp and transfer the cleaning ball 700 in the positioning groove 431 to the recess 610 of the cleaning block 600. It includes a stand 510, a left-right moving device 520, a right-up lifting device 530, and multiple clamping parts 540. The stand 510 is fixedly connected to the base frame 100 and is positioned above the first conveyor 200. The top surface of the stand 510 is provided with a slide rail arranged in the left-right direction. The left-right moving device 520 uses a cylinder slide module. The left-right moving cylinder 521 is fixedly installed on one side of the stand 510 and is used to drive the first mounting plate 522 to move left and right along the slide rail. A limit switch 523 is provided on the side of the stand 510 away from the left-right moving cylinder 521. The limit switch 523 is used to limit the maximum stroke of the first mounting plate 522. By adjusting the position of the limit switch 523, the cleaning block 600 can be precisely aligned with the recess 610. The first mounting plate 522 is made of aluminum alloy with a thickness of 10mm to 15mm, and has sufficient structural strength to support the weight of the lifting device 530 and the clamping part 540.

[0046] The lifting device 530 is fixedly connected to the first mounting plate 522 and is driven by a lifting cylinder 531 to drive the second mounting plate 532 to move vertically. The second mounting plate 532 and the first mounting plate 522 are connected vertically via a guide sleeve 533. It should be noted that in this embodiment, a cylinder is preferred as the power source because it has the advantages of fast response and low cost. However, it is not limited to a cylinder; other power sources such as electric push rods and hydraulic cylinders can also be used, as long as they can achieve the lifting function. The second mounting plate 532 is fixed to the bottom end of the piston rod of the lifting device 530 and is horizontally positioned. The length of the second mounting plate 532 is adapted to the length of the pre-set washing blocks 600 on the first conveyor line 220. Multiple clamping parts 540 are installed on the bottom of the second mounting plate 532. The number of clamping parts 540 is the same as the number of positioning grooves 431, which is 12. The multiple clamping parts 540 are evenly distributed in the front-back direction. The distance between two adjacent clamping parts 540 is the same as the distance between two adjacent washing blocks 600, ensuring that each clamping part 540 can correspond to one positioning groove 431 and one hole 610. Since the clamping parts 540 have two degrees of freedom of movement, they can be called "two-dimensional mechanisms" or "two-dimensional mechanisms" in the mechanical industry.

[0047] The clamping part 540 employs pneumatic grippers 542, which includes a clamping cylinder 541 and two grippers 542. The grippers 542 are made of stainless steel and have anti-slip teeth on the inner side to enhance the clamping force on the cleaning ball 700 and prevent it from falling off during transfer. The clamping part 540 also has a spring pressure column 543, which is installed vertically between the two grippers 542. The spring pressure column 543 includes a guide rod, a spring, and a pressure head. The guide rod is sleeved inside the spring, and the pressure head is fixed to the bottom end of the guide rod and is made of rubber. As the clamping part 540 moves downward, the spring pressure column 543 first abuts against the upper surface of the cleaning ball 700. As the clamping part 540 continues to move downward, the guide rod retracts upward, the spring is compressed, and elastic pressure is generated. This elastic pressure can fix the position of the cleaning ball 700 and prevent the cleaning ball 700 from shifting position during the closing of the gripper 542, ensuring that the gripper 542 can accurately clamp the center position of the cleaning ball 700.

[0048] In addition, the second mounting plate 532 is also equipped with multiple dispensing valves 550. The dispensing valves 550 are located further away from the second conveyor 300 than the clamping part 540, i.e., to the right of the clamping part 540. The multiple dispensing valves 550 are evenly distributed along the front-back direction, and their number is the same as the number of clamping parts 540. Each dispensing valve 550 has an initial position aligned vertically with the recesses 610 of the multiple washing blocks 600 confined on the first conveyor line 220. Specifically, the dispensing valves 550 are pneumatic dispensing valves, model MV-8, capable of dispensing a measured amount of adhesive. The adhesive used is a food-grade hot melt adhesive with a melting point of 80℃ to 100℃, possessing good bonding properties and not producing harmful substances during dishwasher operation, thus not affecting the washing effect.

[0049] When the two-dimensional clamping mechanism 500 resets, the initial position of each dispensing valve 550 is directly above the corresponding hole 610 of the detergent block 600. While the clamping part 540 clamps the cleaning ball 700 downwards, the dispensing valve 550 simultaneously descends to near the hole 610 of the detergent block 600. Simultaneously, while the clamping part 540 clamps the cleaning ball 700, the dispensing valve 550 dispenses 0.1ml to 0.2ml of adhesive into the hole 610. This adhesive facilitates the bonding between the cleaning ball 700 and the hole 610, making it suitable for detergent block production lines without packaging functions and ensuring the product quality of composite detergent blocks. After dispensing, the clamping part 540, holding the cleaning ball 700, sequentially moves upwards and then to the right. At this time, the dispensing valve 550 moves to the right out of the area where the first conveyor 200 is located and enters a standby state.

[0050] Of course, if the dispensing function is not needed, the power supply to the dispensing valve 550 can be directly cut off. Although the dispensing valve 550 still moves with the second mounting plate 532, it will not dispense glue and will not affect the normal processing procedure.

[0051] Compared with existing technologies, the detergent block and cleaning ball embedding assembly has the following significant advantages: First, it is compatible with conventional production lines, eliminating the need for a dedicated composite tablet press. Switching between ordinary detergent blocks 600 and composite detergent blocks can be achieved simply by starting and stopping the components, significantly reducing equipment investment costs. Second, it can produce multiple composite detergent blocks at a time, significantly improving production efficiency. Third, when changing the shape of the cleaning ball 700, only the movable plate 430 with the corresponding positioning groove 431 needs to be replaced, resulting in extremely low modification costs. Fourth, through the coordinated design of multiple components such as the counter, photoelectric sensor 440, and spring pressure column 543, embedding accuracy is ensured, achieving a product qualification rate of over 99%. Fifth, the inclusion of a debris channel, a dust collection channel 360, and an air blowing pipe 450 effectively prevents debris from affecting product quality and improves production stability. In summary, the technical solution of this invention effectively solves many pain points of existing technologies and has promising prospects for industrial application.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
