Detailed Implementation

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0024] like Figure 1-4 As shown, a component stacking mechanism includes: a stacking assembly 2, a material blocking structure 4, and a frame 6. The stacking assembly 2 is detachably connected to the frame 6, and the material blocking structure 4 is disposed at the discharge end of the stacking assembly 2.

[0025] The material blocking structure 4 is used to separate excess material that is sucked up by the external material taking component 1.

[0026] In this embodiment, when the material-picking component 1 picks up the material, the material-blocking structure 4 separates the excess material picked up by the material-picking component 1 through physical blocking and flexible contact. For example, for stacked sheet materials, the material-blocking structure 4 can apply reverse resistance during the picking process, allowing only a single layer of material to be adsorbed, effectively avoiding double-sheet phenomenon. This design not only reduces material waste, but also eliminates the problems of decreased processing accuracy and equipment jamming that may be caused by double-sheet materials entering subsequent processes, reducing production and maintenance costs and meeting the stringent requirements of industrial production for the accuracy of material conveying.

[0027] In this embodiment, the material blocking structure 4 physically blocks and flexibly contacts the excess material, separating the excess material absorbed by the material picking component 1 during the material picking process. For example, it applies reverse resistance to stacked sheet materials, allowing only single-layer adsorption, solving the double-sheet phenomenon, avoiding material waste and subsequent processes caused by double-sheet materials, such as reduced processing accuracy and equipment jamming, reducing production and maintenance costs, and meeting the stringent requirements of industry for conveying accuracy.

[0028] The stacking assembly 2 includes at least two stacking racks 21 to allow for material replenishment without downtime. When the stacking assembly 2 is operating, one stacking rack 21 serves as the working position, and the other as the storage position. The material height in the working stacking rack 21 is monitored in real-time by the material sensing component 3 and fed back to the external sliding module 5. When material is sufficient, the sliding module 5 drives the material-picking component 1 to continuously pick up material. When material is depleted at the working position, the material-picking component 1 switches to picking up material from the storage position and replenishing the working position to reduce downtime during replenishment. The stacking rack 21 includes several limiting... Positioning member 211, a plurality of the aforementioned positioning members 211 are all provided on the frame 6, and the plurality of the aforementioned positioning members 211 surround the material stacking trough 212. The positioning members 211 play a role in restraining the material, so that the material can be neatly stored in the material stacking trough 212; the material stacking trough 212 is used to stack the material, and the material blocking structure 4 includes a plurality of annular rubber rings 41. The plurality of annular rubber rings 41 are sleeved on the discharge end of each of the aforementioned positioning members 211, which can form a flexible barrier, effectively preventing two or more sheets of material from being simultaneously sucked up and discharged by the material picking component 1 and entering the subsequent conveying process, ensuring that only one layer of material is taken away each time;

[0029] In this embodiment, the continuous supply of materials is achieved through the double stacking rack 21 structure. When the material in the stacking rack 21 at the working position is exhausted, the system can automatically switch to the storage position to pick up the material without stopping the machine, which greatly improves production efficiency and reduces the production capacity loss caused by replenishment. The stacking trough 212 formed by the limiting member 211 forms an orderly constraint on the material, making the material neatly stacked, which is convenient for the picking component 1 to accurately position and grab, and improves the picking efficiency. The annular rubber ring 41 of the material blocking structure 4 is sleeved on the upper end of the limiting member 211. During material picking, it effectively separates excess material through physical blocking and flexible contact, avoids double-sheet phenomenon, ensures that only a single layer of material is adsorbed each time, eliminates processing errors and equipment failures caused by double-sheet material, and reduces production and maintenance costs.

[0030] The component stacking mechanism also includes a material sensing component 3, and the stacking component 2 also includes an adjustment structure 22, which is mounted on the frame 6. The material sensing component 3 is detachably connected to the adjustment structure 22. The material sensing component 3 is used to detect the amount of material in the stacking component 2. The adjustment structure 22 is used to adjust the horizontal installation position and vertical installation height of the material sensing component 3.

[0031] In this embodiment, the material sensing component 3 can be selected from a variety of sensor types, such as photoelectric sensors that detect materials by utilizing the characteristics of light reflection or transmission, and ultrasonic sensors that determine the condition of materials by relying on the principle of ultrasonic wave reflection.

[0032] In this embodiment, the material sensing component 3 monitors the material quantity in the stacking component 2 in real time and feeds the material quantity information back to the external sliding module 5. When sufficient material is detected, the sliding module 5 can start the next round of material handling based on the feedback signal after the material handling component 1 completes the current material handling action, thereby achieving continuous and efficient material handling. During the equipment installation and commissioning phase, the position of the material sensing component 3 can be adjusted according to the actual situation through the adjusting structure 22 to achieve the best detection effect and adapt to different production environments and material detection needs. During equipment maintenance, if it is necessary to repair or replace the material sensing component 3, the disassembly and connection method makes the operation more convenient and reduces maintenance time and cost. Adjusting the horizontal and vertical installation height of the material sensing component 3 through the adjusting structure 22 can ensure the best detection effect. At the same time, the disassembly and connection design of the material sensing component 3 and the adjusting structure 22 makes the repair or replacement operation more convenient and reduces maintenance time and cost.

[0033] The frame 6 is provided with a pushing structure 7 at the position of the stacking trough 212. The pushing structure 7 is electrically connected to the material sensing component 3 and is used to push the material in the stacking trough 212.

[0034] In this embodiment, the pushing structure 7 is set at the position of the frame 6 corresponding to the stacking trough 212, and can directly push the material in the trough. When the material sensing component 3 detects a change in the amount of material in the stacking trough 212, it can send a signal to the pushing structure 7 in a timely manner. The pushing structure 7 pushes the material to the discharge end of the stacking trough 212 according to the signal, ensuring that the material is continuously and stably supplied to the material picking stage, ensuring the smooth operation of the entire production process, avoiding production stoppages caused by untimely material supply, and improving production efficiency.

[0035] The frame 6 includes a base 62 and a stacking base plate 63, with the stacking base plate 63 mounted on the base 62. A pushing structure 7 is provided on the base 62 at the position of the stacking trough 212. The pushing structure 7 is electrically connected to the material sensing component 3 and is used to push the material in the stacking trough 212 to a suitable picking position. Several limiting members 211 are mounted on the stacking base plate 63. An adjusting structure 22 is mounted on the base 62 and is used to adjust the position of the material sensing component 3 to meet material quantity detection requirements.

[0036] In this embodiment, the pushing structure 7 and the limiting member 211 cooperate with each other. The former pushes the material to the appropriate picking position, while the latter ensures that the material is neatly positioned, effectively solving the picking problem caused by material accumulation or position deviation and optimizing the material management process. The adjusting structure 22 is used to adjust the position of the material sensing component 3 to adapt to the material quantity detection requirements and ensure that the material sensing component 3 is always in the optimal detection position.

[0037] The material stacking base plate 63 is provided with a plurality of fixing holes 631. The limiting member 211 includes a limiting rod and a locking block 213. The locking block 213 is provided at the lower end of the limiting rod. The locking block 213 is provided with a locking hole. A first locking pin passes through the locking hole. The locking hole and the fixing hole 631 are locked together by the first locking pin. A plurality of annular rubber rings 41 are sleeved on the discharge end of each limiting rod.

[0038] In this embodiment, when materials need to be changed, the operator only needs to loosen each of the first locking pins to easily rotate each limiting rod and change the position of each limiting rod on the stacking base plate 63, thereby changing the shape of the stacking trough 212. This design enables the stacking mechanism to quickly adapt to materials of different shapes and sizes, broadening its application range. Whether it is small precision parts or large block materials, precise positioning and stacking can be achieved by adjusting the position of the limiting rods, improving production efficiency and providing a strong guarantee for the efficient and stable operation of the production process.

[0039] The pushing structure 7 includes a lifting rod 71, a material support plate 72, and a drive module. The drive module is mounted on the base 62 and is electrically connected to the material sensing components 3. There are two or more material sensing components 3, each detecting the amount of material on one stacking rack 21. The drive module controls the lifting rod 71 based on the information from the material sensing components 3, causing the material support plate 72 to lift and lower, thus achieving material lifting and lowering. When material is removed, causing a decrease in the amount of material in the stacking trough 212, the lifting rod 71 can lift the material support plate 72 upwards, keeping the material at a suitable height for easy grabbing by the material handling components. The base 62 has a first through hole at the location of the stacking trough 212, and the stacking base plate 63 has a second through hole at the location of the stacking trough 212. The lifting rod... 71 passes through the first through hole and the second through hole and is connected to the drive module for transmission; the lifting rod 71 is movably mounted on the base 62, and both the lifting rod 71 and the material support plate 72 are located on the stacking trough 212. The first through hole and the second through hole provide the necessary space for the installation and movement of the lifting rod 71. The lifting rod 71 can lift the material support plate 72 as needed, thereby allowing the material support plate 72 to move within the stacking trough 212, thus achieving support, lifting, and height adjustment of the material; the material support plate 72 is mounted on the output end of the lifting rod 71, and the shape of the material support plate 72 can be various shapes such as cross, star, and rhombus, so as to directly support the material on it. It moves up and down with the lifting rod 71 to ensure the stability of the material position within the stacking trough 212, while providing support for the material;

[0040] In this embodiment, the material sensing component 3 detects the amount of material on the stacking rack 21 in real time and feeds the material amount information back to the drive module. The drive module drives the lifting rod 71 to operate, which in turn drives the material support plate 72 to rise and fall, ensuring that the material is always kept at a height that is easy for the material picking component 1 to grab. This design effectively avoids the difficulty of picking up materials due to the reduction of the amount of material in the stacking trough 212, and improves the stability and accuracy of picking up materials. The first through hole and the second through hole provide the necessary space for the installation and movement of the lifting rod 71, so that the lifting rod 71 can flexibly lift and lower the material support plate 72, further optimizing the spatial layout in the stacking trough 212. The material support plate 72 can be selected according to the shape and size of the material to ensure stable support and support of the material, and enhance the versatility and adaptability of the equipment.

[0041] The accessory stacking mechanism also includes a positioning component 8, and the stacking base plate 63 and the base 62 are positioned by the positioning component 8;

[0042] In this embodiment, the positioning component 8 can constrain the relative position of the stacking base plate 63 and the base 62, preventing the stacking base plate 63 from shifting due to factors such as material stacking, ensuring the fixation and stability of the stacking area, and providing a reliable foundation for material stacking and retrieving operations.

[0043] The number of positioning components 8 is two or more sets. Each set of positioning components 8 includes a positioning pin 81 and a positioning post 82. One of the positioning post 82 and the positioning pin 81 is disposed on the base 62 and the other is disposed on the stacking base plate 63. The positioning pin 81 and the positioning post 82 are detachably connected.

[0044] In this embodiment, the positioning component 8 uses a structure of positioning pin 81 and positioning column 82 to achieve rapid positioning of base 62 and stacking base plate 63, which has the advantages of simple assembly and disassembly and simple structure.

[0045] The adjustment structure 22 includes a first upright 221, a first shaft clamp 222, a first horizontal bar 223, and a vertical adjustment component 224. The material sensing component 3 is fixed on the first upright 221. The first upright 221 serves as the carrier of the material sensing component 3, directly supporting and fixing it. It is a fundamental component ensuring that the material sensing component 3 can perform its detection function normally. The first shaft clamp 222 is mounted on the first upright 221 and is detachably connected to the first horizontal bar 223. It is a key component for adjusting the horizontal position of the material sensing component 3. The clamping position on the first horizontal bar 223 can drive the first vertical bar 221 and the material sensing component 3 fixed thereon to move horizontally; the first horizontal bar 223 is detachably connected to the vertical adjustment component 224, which is provided on the base 62 to provide a stable support foundation for the entire adjustment structure 22. At the same time, the vertical position of the first horizontal bar 223 can be finely adjusted when necessary, and the spatial position of the material sensing component 3 can be adjusted in conjunction with the horizontal adjustment; by adjusting the clamping position of the first shaft clamp 222 on the first horizontal bar 223, the horizontal installation position of the material sensing component 3 can be changed.

[0046] In this embodiment, the material sensing component 3 is stably supported by the first upright 221, and the detachable connection between the first shaft clamp 222 and the first crossbar 223 enables flexible adjustment of the horizontal position of the material sensing component. Combined with the fine-tuning function of the vertical adjustment component 224, it can adapt to the material detection needs under different production scenarios and improve the accuracy and reliability of data acquisition. The detachable connection between the components not only facilitates installation and debugging, but also reduces maintenance difficulty and cost. When the production layout is adjusted or the material position changes, the position can be quickly calibrated without reinstallation. By optimizing the detection position of the material sensing component 3, the operating efficiency of material picking and feeding can be effectively improved, and the adaptability of the production line to diversified production needs can be enhanced.

[0047] The vertical adjustment component 224 includes a second shaft clamp 2241, a third shaft clamp 2242, a second horizontal bar 2243, and a second vertical bar 2244. The second vertical bar 2244 is mounted on the base 62 and provides a stable foundation support for the entire vertical adjustment component 224, serving as a reference carrier for the installation and adjustment of other components. The second horizontal bar 2243 is detachably connected to the second vertical bar 2244 via the second shaft clamp 2241. The second horizontal bar 2243 serves as an intermediate connecting component, with one end connected to the second shaft clamp 2241. The second shaft clamp 2241 is connected to the second upright 2244, and the other end is detachably connected to the first crossbar 223 via the third shaft clamp 2242. It plays a connecting role, transmitting vertical adjustment actions while also providing an installation platform for the first crossbar 223. The first crossbar 223 is detachably connected to the second crossbar 2243 via the third shaft clamp 2242. By adjusting the clamping position of the second shaft clamp 2241 on the second upright 2244, the vertical installation height of the material sensing component 3 can be changed.

[0048] In this embodiment, the second upright 2244 serves as a stable support. Combined with the detachable connection of the second shaft clamp 2241, the second crossbar 2243, and the third shaft clamp 2242, the vertical installation height of the material sensing component 3 can be easily adjusted. Simultaneously, the modular design reduces the difficulty of equipment installation and debugging, shortens maintenance time, and reduces downtime losses. Furthermore, precise height adjustment makes material detection information more accurate, which helps subsequent equipment optimize its operating path, reduce energy consumption and material loss, and improve the efficiency of production resource utilization and overall benefits.
