Description

Technical Field

[0001] This invention relates to the field of photovoltaic cell production technology, and more specifically to a rotary vertical box material sorting device based on photovoltaic cell production. Background Technology

[0002] The explanation focuses on the high-yield model of automated photovoltaic cell / box production, which uses PLC and robotic arms to replace manual operation. Taking actions such as box standing and material sorting as examples, the products move along the automated conveyor line at a fixed speed and direction, and the robotic arms complete the above-mentioned different actions.

[0003] However, it should be noted that in the mass production of battery cells, the robotic arm mostly moves according to a preset program. But from the perspective of mechanical wear, in repeated actions, the actual trajectory differs from the preset trajectory. Furthermore, considering the actual production process: Due to various uncontrollable factors (mechanical vibration), the actual position of the battery cells may differ from the preset position, which may cause multiple alarm signals during actual production. Problems such as increased load / operation limitations on the robotic arm, uneven separation of battery boxes, and slippage of the robotic arm gripper may easily lead to collision damage. This invention proposes a solution to these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a rotary vertical box material sorting device based on photovoltaic cell production. In the automated control process of cell production, due to mechanical operation factors or external environmental interference, there is a significant difference between the robotic arm gripping position, the product waiting position and the preset position, which affects product quality and production efficiency.

[0005] The objective of this invention can be achieved through the following technical solution: a rotary vertical box material sorting device based on photovoltaic cell production, including a conveyor belt assembly, wherein the conveyor belt assembly is staggered along the height direction, and a large rocker arm is provided at the middle position of the two conveyor belt assemblies, and a drive motor corresponding to the large rocker arm is provided on the conveyor belt assembly; Cylinder assembly two is installed on both sides of the upper part of the large rocker arm. A directional slider along the length of the large rocker arm is installed at the end of the output shaft of cylinder assembly two. The directional slider and the large rocker arm are slidably connected through cylinder assembly two. Cylinder assembly one is fixedly installed on the directional slider. A pressing block is rotatably installed at the end of the output shaft of cylinder assembly one. The pressing block is linearly arranged along the width of the large rocker arm through cylinder assembly one.

[0006] The following configuration is further provided: an infrared sensing component is provided on the conveyor belt assembly, and a baffle assembly is provided on one side of the conveyor belt assembly corresponding to its conveying direction.

[0007] The configuration is further defined as follows: the number of baffle assemblies along the conveying direction of the conveyor belt assembly is two, and the baffle assembly consists of a baffle and an actuating component.

[0008] The rotation point between the large rocker arm and the conveyor belt assembly is located at a point halfway down the length of the large rocker arm.

[0009] The following configuration is further provided: a transfer sleeve is rotatably mounted on the lower part of the large rocker arm; a take-up cable assembly is provided on the lower side of the two sections of the conveyor belt assembly corresponding to the transfer sleeve; and a guide cable is provided between the take-up cable assembly and the transfer sleeve.

[0010] A further configuration is provided: a rocker wheel is rotatably mounted on the middle section of the transfer cable sleeve, and a gravity pendulum is mounted on the rocker wheel.

[0011] The following actions are included during use: Action 1: The conveyor belt assembly is set to a horizontal position and a vertical position along its conveying direction and the setting direction of the large rocker arm, respectively, and the large rocker arm is set in a vertical direction in the initial state; Action 2: The large rocker arm rotates in a direction close to the flat position. After the position of the directional slider is adjusted by cylinder assembly 2, cylinder assembly 1 drives the two pressing blocks to move in opposite directions and completes the clamping action of the battery cell box. Action 3: After completing Action 2, the large rocker arm rotates in a direction close to the vertical position, and after completing the alignment of the battery cell box through one of the baffle assemblies, the large rocker arm returns to the initial position and repeats Action 1 to Action 2. Action 4: After the cell box alignment is completed, the vertical conveyor belt assembly drives the aligned cell box for directional transport, and completes the arrangement action through another baffle assembly.

[0012] Further configuration: In action two, the clamping point of the pressing block on the battery cell box is located at a position higher than half the height of the battery cell box.

[0013] The present invention has the following beneficial effects: 1. Firstly, improvements were made to the clamping action by using a rotation point design where the large rocker arm rotates below half its own length. Essentially, this utilizes the natural swinging process of gravity, combined with the height adjustment function of the two pairs of directional sliders in the cylinder assembly. This allows the pressing block to adapt to different specifications of battery cell boxes, and the clamping point is above half the height of the battery cell box, effectively preventing material tipping during clamping. The pressing block adopts a rotating installation structure, which can adapt to slight deviations of the battery cell box (naturally aligning), reducing damage caused by rigid contact. At the same time, the angle correction mechanism of the gravity pendulum ball and rocker wheel, as well as the buffering and limiting effect of the traction guide cable, doubly suppress the start-stop vibration and overshoot of the large rocker arm, ensuring precise and controllable clamping, rotation, and reset actions. Essentially, this is used to solve the problem of grasping misalignment caused by trajectory deviation and vibration of the robotic arm.

[0014] 2. To summarize the above, the rotation of the large rocker arm and the speed of the conveyor belt are controlled in coordination by the drive motor. This, along with the alignment and arrangement of the connecting baffle assembly, forms a continuous process of "grabbing - transferring - alignment - arrangement." This avoids frequent alarms and shutdowns caused by positional deviations in traditional equipment, reducing production interruptions. Angle correction and vibration buffering are achieved through mechanical structures (gravity pendulum, traction guide cable, transfer sleeve, etc.), eliminating the need for complex mechanical structure design. This reduces trajectory deviations caused by mechanical wear, lowers equipment load limits, reduces the incidence of malfunctions such as clamp slippage and collision damage, and extends the service life of the equipment.

[0018] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Regarding the automated control process in battery cell production, mechanical operating factors or external environmental interference can cause significant differences between the robotic arm's gripping position, the product's ready-to-be-picked position, and the preset position, thus affecting product quality and production efficiency. The following technical solution is proposed to address this issue: Reference Figures 1-5 The rotary vertical box material sorting equipment based on photovoltaic cell production in this embodiment includes a conveyor belt assembly 1, which is staggered along the height direction, and a large rocker arm 3 is provided in the middle of the two conveyor belt assemblies 1. A drive motor 4 corresponding to the large rocker arm 3 is provided on the conveyor belt assembly 1. Cylinder assembly 2 7 is installed on both sides of the upper part of the large rocker arm 3. A directional slider 13 along the length of the large rocker arm 3 is installed at the end of the output shaft of cylinder assembly 2 7. The directional slider 13 is slidably connected to the large rocker arm 3 through cylinder assembly 2 7. Cylinder assembly 1 6 is fixedly installed on the directional slider 13. A pressing block 12 is rotatably installed at the end of the output shaft of cylinder assembly 1 6. The pressing block 12 is linearly arranged along the width of the large rocker arm 3 through cylinder assembly 1 6. An infrared sensing component 5 is installed on the conveyor belt assembly 1. A baffle assembly 2 is installed on one side of the conveyor belt assembly 1 corresponding to its conveying direction. There are two baffle assemblies 2 along the conveying direction of the conveyor belt assembly 1. The baffle assembly 2 consists of a baffle and an actuation component. The rotation point between the large rocker arm 3 and the conveyor belt assembly 1 is lower than half the length of the large rocker arm 3.

[0020] Basic structural composition: (Refer to) Figure 1 The overall structure is essentially the same as a conventional conveyor belt structure, with the key difference being the use of a staggered dual conveyor belt design. These belts are responsible for horizontal and vertical conveying, respectively. The horizontal conveyor belt transports the battery cell boxes to be processed to the working area of ​​the large rocker arm 3, while the vertical conveyor belt receives the aligned and sorted battery cell boxes for subsequent transport. For details, please refer to [link / reference needed]. Figure 5The movement pattern in the process, the running speed of the conveyor belt assembly 1 and the movement rhythm of the large rocker arm 3 are controlled in coordination by the drive motor 4 to ensure precise connection between material conveying and gripping actions; The infrared sensing principle of the conveyor belt is similar. It monitors the position information of the battery box on the conveyor belt assembly 1 in real time. When the battery box is detected to have reached the preset gripping area, it immediately sends a signal to the drive motor 4 and cylinder assembly to trigger the gripping action of the large rocker arm 3, realizing the automated response of "processing upon arrival". The structure of its baffle assembly 2 is also relatively simple. The baffle is driven by a motor-like structure to rotate within a 90° range. Its purpose is to cooperate with the subsequent alignment and arrangement actions. The key point lies in the movement of the large rocker arm 3. It rotates directionally around a pivot point located halfway down its length, initially maintaining a vertical orientation. Driven by the drive motor 4, it rotates towards the horizontal conveyor belt to reach the gripping angle, completing the clamping action before rotating back towards the vertical conveyor belt to reset. Its rotation trajectory is controlled by mechanical limits and a closed-loop motor mechanism to ensure operational stability. The two cylinder assemblies are primarily used to adjust the position and clamping force of the battery cell box. For example, cylinder assembly 7 is fixed to both sides of the upper end of the large rocker arm 3. When its output shaft extends or retracts, it drives the directional slider 13 along the length of the large rocker arm 3. The pressing block 12 can be adjusted vertically by sliding in a certain direction, allowing it to adapt to battery cell boxes of different heights and expanding the applicability of the equipment. The cylinder assembly 6 is fixed on the directional slider 13, and the output shaft drives the two pressing blocks 12 to move in opposite directions along the width of the large rocker arm 3 to complete the clamping and releasing action of the battery cell box. The pressing block 12 adopts a rotating installation design, which can adaptively adjust its angle according to the slight displacement of the battery cell box during the clamping process, avoiding material damage caused by rigid clamping. Its key function is to use gravity to adjust the swing direction of the battery cell box, which facilitates the subsequent straightening action.

[0021] Example 2: Supplementary explanation of the movement process of the large rocker arm: The lower part of the large rocker arm 3 is rotatably mounted with a transfer sleeve 11. The lower part of the conveyor belt assembly 1 corresponding to the two sections of the transfer sleeve 11 is provided with a take-up cable assembly 8. A guide cable is provided between the take-up cable assembly 8 and the transfer sleeve 11. The middle section of the transfer sleeve 11 is rotatably mounted with a rocker wheel 10. A gravity pendulum ball 9 is mounted on the rocker wheel 10.

[0022] Solution Description: First, it should be noted that mechanical vibration is a problem inherent in any form of mechanical operation, especially when considering... Figure 2The rotation process of the large rocker arm 3 is not a completely symmetrical structure, and the battery cell box itself has a certain gravity. Therefore, this invention first uses a non-perfectly symmetrical method to "differentiate" the gravity distribution, so as to avoid a significant difference between the actual rotation angle of the large rocker arm 3 and the preset rotation angle due to large gravity differences. In addition, the key part is to balance the gravity changes through "tension changes", as shown below: The transfer sleeve 11 is rotatably mounted on the lower end of the large rocker arm 3. The take-up cable assembly 8 is located on the lower side of the two sections of the conveyor belt assembly 1 corresponding to the transfer sleeve 11. The two are connected by traction guide cables. When the large rocker arm 3 rotates, the take-up cable assembly 8 synchronously winds up and unwinds the traction guide cables. The tension of the cables helps to limit and buffer the rotation trajectory of the large rocker arm 3, preventing the large rocker arm 3 from overshooting due to inertia. This can further limit the binding direction of the two traction guide cables relative to the transfer sleeve 11, ensuring that the two traction guide cables can rotate clockwise or counterclockwise when the transfer sleeve 11 rotates in a directional manner. This can be understood as: when the large rocker arm 3 rotates in a directional manner, the two take-up cable assemblies 8 will also rotate in an adaptive manner. The take-up cable assembly 8 is essentially a combination of a motor and a reel structure. The rocker wheel 10 is rotatably installed in the middle section of the transfer cable sleeve 11, and the gravity pendulum 9 is fixed on the rocker wheel 10. During the rotation of the large rocker arm 3, the gravity pendulum 9 always remains vertically downward due to gravity. The rotation of the rocker wheel 10 provides feedback on the tilt angle of the large rocker arm 3, forming a mechanical angle compensation mechanism to further correct the rotation accuracy of the large rocker arm 3. However, its auxiliary role is to "consume" the inertial influence that may be generated during the rotation of the large rocker arm 3 through the natural swinging process of the gravity pendulum 9. In summary, the buffer limit of the guide cable and the angle feedback of the gravity pendulum 9 form a dual stability guarantee, effectively suppressing the vibration and overshoot of the large rocker arm 3 during start-up and shutdown, ensuring precise control of clamping, rotation, and reset actions, and improving the stability of the battery cell box transfer process. This is mainly to meet the subsequent alignment of the clamped battery cell box. Angle correction and buffering are achieved through mechanical structures (gravity pendulum 9, guide cable), eliminating the need for complex PLC program compensation, reducing the complexity of the control system, reducing program debugging and maintenance costs, and improving the reliability of equipment operation.

[0023] Example 3: Supplementary explanation of the action process based on Examples 1 and 2: The following actions are included during use: Action 1: The conveyor belt assembly 1 is set to a horizontal position and a vertical position along its conveying direction and the setting direction of the large rocker arm 3, respectively, and the large rocker arm 3 is set in a vertical position in the initial state; Action 2: The large rocker arm 3 rotates in a direction close to the flat position. After the position of the directional slider 13 is adjusted by the cylinder assembly 2 7, the cylinder assembly 1 6 drives the two pressing blocks 12 to move in opposite directions and complete the clamping action of the battery cell box. In Action 2, the clamping point of the pressing block 12 on the battery cell box is higher than half of the height of the battery cell box. Action 3: After completing Action 2, the large rocker arm 3 rotates in a direction close to the vertical position, and after completing the alignment action of the battery cell box through one of the baffle assemblies 2, the large rocker arm 3 returns to the initial position and repeats Action 1 to Action 2. Action 4: After the cell box alignment is completed, the vertical conveyor belt assembly 1 drives the aligned cell box to be transported in a directional manner, and completes the arrangement action through another baffle assembly 2.

[0024] The above actions are described in detail as follows: The horizontal conveyor belt assembly 1 starts and conveys the battery cell boxes at a preset speed, such as... Figure 5 As shown, the large rocker arm 3 maintains its initial vertical position, and cylinder assemblies 1 / 2 6 / 7 are all in the reset state. The pressing block 12 is open, and the infrared sensing component 5 continuously monitors the position of the battery cell box on the flat conveyor belt. When the infrared sensing component 5 detects that the battery cell box has reached the gripping area, the drive motor 4 drives the large rocker arm 3 to rotate in the direction of the flat position. After the large rocker arm 3 reaches the preset gripping angle, cylinder assembly 2 7 is activated to adjust the directional slider 13 to the appropriate height so that the pressing block 12 is aligned with the clamping point above half the height of the battery cell box. Then, cylinder assembly 1 6 drives the two pressing blocks 12 to move in opposite directions to complete the flexible clamping of the battery cell box (the clamping point above half the height can prevent the battery cell box from tipping over). However, its key purpose is to use the gravity of the battery cell box for automatic alignment. However, its swing process may aggravate the shaking process of the large rocker arm 3. Therefore, the protection process of the large rocker arm 3 by the two winding assemblies 8 in embodiment 2 is further utilized. After clamping is completed, the drive motor 4 drives the large rocker arm 3 to rotate and reset in the vertical direction. During the rotation, the transfer cable sleeve 11 and the take-up cable assembly 8 are buffered by the guide cable and the gravity pendulum ball 9 corrects the angle to ensure that the large rocker arm 3 rotates smoothly. When the large rocker arm 3 returns to the vertical position, the baffle assembly 2 near the reset side is activated. The battery cell box is aligned to the preset conveying position by the swing of the baffle. Then the cylinder assembly 6 releases the pressing block 12, and the large rocker arm 3 resets to the initial state, ready for the next gripping. The key is to explain the arrangement process of multiple cell boxes: Refer to Figure 5 To explain, the battery cell box is first aligned by one of the baffle assemblies 2, while the battery cell box placed on the conveyor belt assembly 1 continues to be transported. The other baffle assembly 2 is used to limit its movement. The purpose is to arrange multiple battery cell boxes tightly to facilitate the gripping action of the robotic arm.
