Description

Technical Field

[0001] This application relates to the field of infrared emitting tube array production equipment technology, specifically an infrared emitting tube array unloading and stacking mechanism. Background Technology

[0002] Infrared emitting diode arrays, as core components of photoelectric sensors, are widely used in security monitoring, smart homes and other fields.

[0003] However, existing material handling and stacking mechanisms are insufficient to meet the surge in production demands brought about by increasing market demand, and cannot keep pace with the high-efficiency production rhythm. In high-frequency production environments, the existing material handling method using robotic arms and conveyor belts struggles to achieve precise material positioning, potentially leading to inaccurate material placement. This can affect subsequent stacking, packaging, and other processes, and may even cause production accidents or product quality issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an infrared emitting tube feeding and stacking mechanism, which has advantages such as meeting the needs of high-efficiency production rhythms. It solves the problem that existing feeding and stacking mechanisms are unable to meet the large production tasks brought about by the growth of market demand and cannot match the high-efficiency production rhythm. In high-paced production environments, the existing feeding method of robotic arms and conveyor belts is difficult to achieve accurate material positioning, which may lead to inaccurate material placement, affecting subsequent stacking, packaging and other processes, and may even cause production accidents or product quality problems.

[0005] To achieve the above objectives, this application provides the following technical solution: an infrared emitting tube stacking and unloading mechanism, comprising a housing and a receiving rack. A support plate is fixedly connected inside the housing. Two vertical plates arranged in a mirror image are fixedly connected to one side of the upper end of the support plate. Mounting seats are fixedly connected to the upper ends of the two vertical plates. Four positioning columns arranged in a rectangular array are fixedly connected to the upper end of the mounting seats. Four positioning slots arranged in a rectangular array are opened at the bottom end of the receiving rack. Two guide rods arranged in a mirror image are fixedly connected to one side of the receiving rack. A handle is fixedly connected to the end of the receiving rack away from the guide rods. A conveying trough is fixedly connected to the upper end of the housing. A photoelectric sensor is fixedly connected to one side of the conveying trough.

[0006] The above solution utilizes the positioning pins on the mounting base and the positioning grooves at the bottom of the receiving rack to achieve precise positioning and stable placement of the receiving rack on the mounting base. This ensures accurate positioning of the receiving rack during subsequent material unloading and stacking, avoiding stacking chaos or damage caused by positional deviations, thus guaranteeing stacking quality and product integrity. The guide rod on one side of the receiving rack guides the infrared emitting tubes entering the rack, arranging them in a predetermined direction and position, improving stack neatness and compactness, facilitating subsequent storage, transportation, and use, and also enhancing space utilization. One end of the receiving rack... The addition of handles allows operators to easily pick up and place the receiving rack, improving operational convenience and efficiency. Once the receiving rack is full of products, it can be quickly removed and replaced with a new empty receiving rack to continue production, reducing downtime. The upper part of the outer shell is fixedly connected to the conveyor trough, providing a stable conveying channel for the infrared emitting tube array, ensuring that products can continuously and smoothly enter the unloading and stacking area. A photoelectric sensor on one side of the conveyor trough can detect in real time whether the infrared emitting tube array has reached the designated position, and promptly feed the signal back to the control system to trigger subsequent gripping and stacking actions, realizing the automation and precise control of the production process and improving production efficiency.

[0007] Furthermore, a first pneumatic push rod is fixedly connected to one end of the upper side of the support plate away from the upright plate, and four first positioning rods arranged in a rectangular array are fixedly connected to the upper end of the support plate away from the upright plate. A lifting plate is fixedly connected to the telescopic end of the first pneumatic push rod, and a positioning hole is opened through the lifting plate.

[0008] With the above scheme, the first pneumatic push rod serves as the power source, and its telescopic movement can precisely control the lifting stroke of the lifting plate. The four first positioning rods arranged in a rectangular array cooperate with the positioning holes on the lifting plate to provide a reliable guiding effect for the lifting of the lifting plate, which can effectively prevent the lifting plate from shaking or deviating during the lifting process.

[0009] Furthermore, a second pneumatic push rod is fixedly connected to the upper end of the lifting plate, and a positioning plate is fixedly connected to one side of the upper end of the lifting plate. The positioning plate has four through holes arranged in a rectangular array inside, and a second positioning rod is slidably connected inside each of the through holes. A moving plate is fixedly connected to one side of each of the four second positioning rods. A baffle is fixedly connected to each pair of the ends of the four second positioning rods away from the moving plate. A support arm is fixedly connected to the end of the moving plate away from the second positioning rods.

[0010] Through the above scheme, the second pneumatic push rod, as a power drive component, can precisely control the horizontal movement stroke of the clamping device, ensuring that the clamping device moves along the preset path, achieving precise gripping and placement of the infrared emitting tube array, effectively improving the accuracy and consistency of material stacking, and reducing production problems caused by positional deviations. The four second positioning rods, distributed in a rectangular array, slide in cooperation with the through holes on the positioning plate, providing stable guidance for the horizontal movement of the clamping device, preventing the clamping device from deflecting, shaking, or tilting during movement, ensuring a smooth and stable movement process, and improving the stability and reliability of the entire mechanism.

[0011] Furthermore, a fixing block is fixedly connected to one side of the inside of the support arm, and grippers are rotatably connected to both sides of the fixing block. A rotating shaft is rotatably connected inside each gripper, and a connecting rod is rotatably connected to the outer wall of each of the two rotating shafts. A connecting block is rotatably connected between the two connecting rods.

[0012] With the above scheme, the drive device directly drives the connecting block to move up and down, and the connecting rod converts the linear motion into the rotational opening and closing action of the gripper. The energy transmission path is short and the power loss is small, ensuring that the gripper can respond quickly to the drive signal and achieve efficient and stable clamping and release.

[0013] Furthermore, a third pneumatic push rod is fixedly connected to one side of the upper end of the support arm, and the telescopic end of the third pneumatic push rod passes through the fixing block and is fixedly connected to the connecting block.

[0014] With the above scheme, the third pneumatic push rod serves as the power source for the opening and closing of the gripper. The third pneumatic push rod is directly connected to the connecting block through the telescopic end, converting the linear motion of the cylinder into the opening and closing action of the gripper.

[0015] Furthermore, the receiving rack is located on the upper end of the mounting base, and the four positioning posts are all slidably positioned inside the positioning grooves.

[0016] By aligning the four positioning slots at the bottom of the receiving rack with the four positioning posts at the top of the mounting base using the above method, the installation of multiple receiving racks can be completed.

[0017] Furthermore, all four first positioning rods are slidably disposed inside the positioning holes.

[0018] With the above solution, the lifting plate moves stably and does not deviate during the movement of the lifting plate by sliding the first positioning rod in the positioning hole.

[0019] Furthermore, the telescopic end of the second pneumatic push rod passes through one end of the positioning plate and is fixedly connected to the moving plate.

[0020] With the above solution, the second pneumatic push rod serves as the power source, directly connecting the positioning plate and the moving plate without the need for additional transmission components. This allows the horizontal power to be directly applied to the clamping device, ensuring that the clamping device can respond quickly during horizontal movement.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This infrared emitting tube stacking mechanism utilizes a positioning post on the mounting base that engages with a positioning groove at the bottom of the receiving rack. This ensures precise positioning and stable placement of the receiving rack on the mounting base, guaranteeing accurate rack placement during subsequent stacking and preventing stacking chaos or damage caused by positional deviations. This safeguards stacking quality and product integrity. A guide rod on one side of the receiving rack guides the infrared emitting tubes entering the rack, arranging them in a predetermined direction and position. This improves stack neatness and compactness, facilitating subsequent storage, transportation, and use, while also enhancing space utilization. A handle is provided at one end of the material rack, making it easy for operators to pick up and put down the receiving rack, improving the convenience and efficiency of operation. After the receiving rack is full of products, it can be quickly removed and replaced with a new empty receiving rack to continue production, reducing downtime. The upper part of the outer shell is fixedly connected to the conveying trough, providing a stable conveying channel for the infrared emitting tube array, ensuring that products can continuously and smoothly enter the unloading and stacking area. The photoelectric sensor on one side of the conveying trough can detect in real time whether the infrared emitting tube array has reached the designated position, and promptly feed the signal back to the control system to trigger subsequent gripping and stacking actions, realizing the automation and precise control of the production process and improving production efficiency.

By cooperating with the positioning posts 5 on the mounting bases 4 and the positioning slots 7 at the bottom of the receiving rack 6, the receiving rack 6 is accurately positioned and stably placed on the mounting bases 4. This ensures that the receiving rack 6 is accurately positioned during subsequent stacking, avoiding stacking chaos or damage caused by positional deviations, thus guaranteeing stacking quality and product integrity. Two mirror-distributed guide rods 8 are fixedly connected to one side of the receiving rack 6. These guide rods 8 guide the infrared emitting tubes entering the receiving rack 6, ensuring that the emitting tubes follow a predetermined direction. The orderly arrangement of the positions helps to improve the neatness and compactness of the stacking, which facilitates subsequent storage, transportation and use. The end of the receiving rack 6 away from the guide rod 8 is fixedly connected to a handle 9. The handle 9 at one end of the receiving rack 6 makes it easy for operators to pick up and put down the receiving rack 6, which improves the convenience and efficiency of operation. After the receiving rack 6 is full of products, it can be quickly removed and replaced with a new empty receiving rack 6 to continue production, reducing downtime. The upper end of the outer shell 1 is fixedly connected to the conveying trough 10, and a photoelectric sensor 11 is fixedly connected to one side of the conveying trough 10. The upper end of the outer shell 1 is fixedly connected to the conveying trough 10, which provides a stable conveying channel for the infrared emitting tube row, ensuring that the products can enter the unloading and stacking area continuously and smoothly.

A lifting plate 14 is fixedly connected to the telescopic end of the first pneumatic push rod 12. A positioning hole 15 is opened through the lifting plate 14. The first pneumatic push rod 12 serves as a power source, and its telescopic movement can precisely control the lifting stroke of the lifting plate 14. The four first positioning rods 13 arranged in a rectangular array cooperate with the positioning hole 15 on the lifting plate 14 to provide a reliable guiding effect for the lifting of the lifting plate 14, which can effectively prevent the lifting plate 14 from shaking or deviating during the lifting process. A second pneumatic push rod 16 is fixedly connected to the upper end of the lifting plate 14. A positioning plate 17 is fixedly connected to one side of the upper end of the lifting plate 14. Four through holes 18 arranged in a rectangular array are opened inside the positioning plate 17. The through holes 18 are evenly slidable inside. The device is dynamically connected to a second positioning rod 20. A movable plate 19 is fixedly connected to one side of each of the four second positioning rods 20. A baffle 21 is fixedly connected to each pair of the ends of the four second positioning rods 20 away from the movable plate 19.

The second pneumatic push rod 16 serves as a power drive component and can precisely control the horizontal movement stroke of the clamping device. This ensures that the clamping device moves along a preset path, enabling precise gripping and placement of the infrared emitting tube array. This effectively improves the accuracy and consistency of material stacking and reduces production problems caused by positional deviations. The four second positioning rods 20, arranged in a rectangular array, slide in conjunction with the through holes 18 on the positioning plate 17, providing a stable guide for the horizontal movement of the clamping device. This prevents the clamping device from deflecting, shaking, or tilting during movement, ensuring a smooth and stable movement and improving the stability and reliability of the entire mechanism.

[0033] Please see Figure 2 , Figure 3 and Figure 5A fixed block 23 is fixedly connected to one side of the support arm 22. Grippers 24 are rotatably connected to both sides of the fixed block 23. Rotary shafts 25 are rotatably connected inside each gripper 24. Connecting rods 26 are rotatably connected to the outer walls of both rotating shafts 25. A connecting block 27 is rotatably connected between the two connecting rods 26. The drive device directly drives the connecting block 27 to move up and down. The connecting rods 26 convert linear motion into the rotational opening and closing action of the grippers 24. The energy transmission path is short, and the power loss is small, ensuring that the grippers 24 can quickly respond to the drive signal, achieving efficient and stable clamping and release. The upper side of the support arm 22... A third pneumatic push rod 28 is fixedly connected. The telescopic end of the third pneumatic push rod 28 passes through the fixed block 23 and is fixedly connected to the connecting block 27. The third pneumatic push rod 28 serves as the power source for the opening and closing of the gripper 24. The third pneumatic push rod 28 is directly connected to the connecting block 27 through its telescopic end, converting the linear motion of the cylinder into the opening and closing action of the gripper 24. The receiving rack 6 is set on the upper end of the mounting base 4. The four positioning pins 5 are all slidably set inside the positioning grooves 7. By aligning the four positioning grooves 7 at the bottom of the receiving rack 6 with the four positioning pins 5 at the upper end of the mounting base 4, the installation of the multiple receiving racks 6 can be completed.

[0034] Please see Figure 2 , Figure 4 and Figure 5 All four first positioning rods 13 are slidably set inside the positioning holes 15. During the movement of the lifting plate 14, the sliding of the first positioning rods 13 in the positioning holes 15 ensures that the movement of the lifting plate 14 is stable and will not deviate. The telescopic end of the second pneumatic push rod 16 passes through one end of the positioning plate 17 and is fixedly connected to the moving plate 19. The second pneumatic push rod 16 serves as a power source, directly passing through the positioning plate 17 and connecting to the moving plate 19. No additional transmission components are required, so that the horizontal power is directly applied to the clamping device, ensuring that the clamping device can respond quickly in horizontal movement.

[0035] In this embodiment, the infrared emitting tube stacking mechanism uses the positioning post 5 on the mounting base 4 to cooperate with the positioning groove 7 at the bottom of the receiving rack 6. This ensures the precise positioning and stable placement of the receiving rack 6 on the mounting base 4, guaranteeing accurate positioning of the receiving rack 6 during subsequent stacking. This avoids stacking chaos or damage caused by positional deviations, ensuring stacking quality and product integrity. The guide rod 8 on one side of the receiving rack 6 guides the infrared emitting tubes entering the receiving rack 6, arranging them in an orderly manner according to a predetermined direction and position. This improves the neatness and compactness of the stacking, facilitating subsequent storage, transportation, and use, while also enhancing space utilization. The receiving rack 6 is equipped with a handle 9 at one end, which makes it easy for operators to pick up and put down the receiving rack 6, improving the convenience and efficiency of operation. After the receiving rack 6 is full of products, it can be quickly removed and replaced with a new empty receiving rack 6 to continue production, reducing downtime. The upper end of the outer shell 1 is fixedly connected to the conveying trough 10, which provides a stable conveying channel for the infrared emitting tube array, ensuring that the products can enter the unloading and stacking area continuously and smoothly. The photoelectric sensor 11 set on one side of the conveying trough 10 can detect in real time whether the infrared emitting tube array has reached the designated position and promptly feed the signal back to the control system to trigger subsequent gripping and stacking actions, realizing the automation and precise control of the production process and improving production efficiency.

[0036] It should be noted that the mounting base 4 is tilted, so that the upper receiving rack 6 has a certain degree of tilt, allowing the infrared emitting tube array placed on the upper end of the guide rod 8 to slide to one side of the receiving rack 6 by gravity.

[0037] The working principle of the above embodiments is as follows:

[0038] The operator aligns the four positioning slots 7 at the bottom of the receiving rack 6 with the four positioning posts 5 at the top of the mounting base 4, inserts them precisely, and places the receiving rack 6 stably on the mounting base 4, ready to receive the infrared emitting tube arrays to be stacked. The infrared emitting tube arrays continuously and smoothly enter the unloading and stacking area through the conveying trough 10 at the top of the outer shell 1. The photoelectric sensor 11 on one side of the conveying trough 10 detects in real time whether the emitting tubes have reached the designated position. When the photoelectric sensor 11 detects that the infrared emitting tube array has reached the designated position, it immediately feeds back the signal to the control system. The control system then issues a command to initiate the gripping action. The first pneumatic push rod 12 is activated, and its telescopic end drives the lifting plate 14 to descend steadily along the four first positioning rods 13, so that the gripper 24 reaches the appropriate gripping height. The third pneumatic push rod 28 is activated, and its telescopic end drives the connecting block 27 to descend. Through the transmission action of the connecting rod 26, the linear motion is converted into the rotational opening and closing action of the gripper 24, so that the gripper 24 clamps the infrared emitting tube array and removes the infrared emitting tube array from the conveying trough 10. The second pneumatic push rod 16 is activated, and its telescopic end directly drives the... The movable plate 19 slides horizontally along the four second positioning rods 20, driving the support arm 22 and gripper 24 to move horizontally towards the receiving rack 6. This causes the gripper 24 to hold the infrared emitting tube array and move it horizontally to one side of the receiving rack 6, ready for stacking. The third pneumatic push rod 28 is activated again, and its telescopic end drives the connecting block 27 to rise. Through the transmission action of the connecting rod 26, the gripper 24 releases the infrared emitting tube array, accurately placing the infrared emitting tube array on the guide rod 8 on one side of the receiving rack 6. The guide rod 8 guides the falling infrared emitting tube array, causing it to move according to a predetermined path. The infrared emitting tubes are arranged in an orderly manner according to their direction and position, improving the neatness and compactness of the stack. The guide rod 8 guides the falling infrared emitting tubes to be arranged in an orderly manner according to the predetermined direction and position. The above steps are repeated to continuously grab, convey, and stack the infrared emitting tubes until the receiving rack 6 is full of products, improving the neatness and compactness of the stack. When the receiving rack 6 is full of products, the operator can quickly remove it from the mounting base 4 through the handle 9 at one end of the receiving rack 6 and replace it with a new empty receiving rack 6 to continue production, reducing downtime and improving production efficiency.
