Description

Technical Field

[0001] This utility model relates to the field of photovoltaic silicon plate transmission technology, specifically to a horizontal transmission device based on a synchronous belt. Background Technology

[0002] In the horizontal transport of precision workpieces such as photovoltaic silicon panels and brittle electronic substrates, traditional conveying devices often face problems such as insufficient transmission stability, rapid equipment wear and tear, and high maintenance costs. Specifically: Existing horizontal conveyor systems mostly employ planar or symmetrical roller sets for transmission. The contact position between the workpiece and the conveyor belt is fixed. After prolonged operation, specific areas where the conveyor belt contacts the workpiece are prone to localized wear due to continuous friction, leading to decreased transmission accuracy and requiring frequent conveyor belt replacements, resulting in short maintenance cycles. Furthermore, the fixed conveyor belt position prevents dynamic adjustment of the contact area to distribute wear, resulting in a short equipment lifespan and high overall costs.

[0003] Photovoltaic silicon panels are sensitive to transmission pressure. Traditional rigid conveyor belts lack a buffer structure and are prone to chipping and scratching of workpiece edges and surfaces due to vibration or uneven pressure, resulting in a high defect rate. At the same time, the conveyor belt is prone to inward denting or warping due to uneven force during operation, which further affects the transmission stability. Utility Model Content

[0004] Therefore, it is necessary to provide a horizontal transmission device based on synchronous belts to address the existing technical problems.

[0005] To solve the problems of the existing technology, the technical solution adopted by this utility model is as follows: This utility model provides a horizontal conveying device based on a synchronous belt, including a frame, on which two conveyors are mounted symmetrically along a vertical center plane and arranged in a V-shape. The conveyor belts on the two conveyors respectively adhere to both sides of the workpiece for conveying. Each conveyor includes a conveyor shaft and a conveyor belt. The conveyor shaft is rotatably mounted on the frame, and the conveyor belt is drivenly connected to the conveyor shaft. The conveyor belt can be displaced along the inclined direction of the conveyor. A pushing mechanism is mounted on the frame and is drivenly connected to the conveyor belt.

[0006] On one hand, the shaft length of the transmission shaft is greater than the width of the transmission belt. The transmission shaft is provided with transmission roller teeth, and the inner sidewall of the transmission belt is provided with an inner tooth layer. The transmission belt meshes with the transmission shaft, and the pushing mechanism is connected to the transmission belt. The transmission belt can slide on the frame along the axial direction of the transmission shaft.

[0007] In order to achieve stable transmission of the conveyor belt, in this embodiment, the pushing mechanism includes two sets of first linear drivers, a first transmission frame, and a horizontal transmission plate, each corresponding to one of the two conveyors. The first linear drivers are fixedly installed at the bottom of the frame, and the output end of the first linear drivers is fixedly connected to the first transmission frame. The output direction of the first linear drivers is consistent with the tilt direction of one of the conveyors. Horizontal transmission plates are installed at both the upper and lower ends of each conveyor belt on the side close to or far from the center plane of symmetry, and the horizontal transmission plates are fixedly connected to the first transmission frame.

[0008] To prevent the conveyor belt from warping or folding during the pushing process, which would result in an uneven surface and affect the transmission effect, the following structure was designed to solve the above problems: a back connecting plate is provided on the side of the conveyor belt away from the center plane of symmetry. The surface of the back connecting plate is in contact with the surface of the conveyor belt. The upper and lower ends of the back connecting plate are fixedly connected to two horizontal transmission plates respectively. Several back connecting plates are provided along the transmission direction.

[0009] On the other hand, the pushing mechanism includes two sets of second linear drivers and a pushing frame, each corresponding to one of the two transmitters. An inclined guide rail is provided on the frame along the tilt direction of the transmitter. The pushing frame is slidably mounted on the frame via the inclined guide rail. The second linear driver is fixedly installed below the frame. The output end of the second linear driver is fixedly connected to the pushing frame. The transmitter is fixedly installed on the pushing frame.

[0010] To improve the stability of the conveyor belt when transporting silicon plates, the following structure is designed: each conveyor belt is equipped with a limiting baffle in the middle, which is fixedly installed on the frame, and the outer wall of the limiting baffle is in contact with the inner wall of the conveyor belt.

[0011] Preferably, the outer surface of the conveyor belt is made of a wear-resistant material.

[0012] Preferably, the middle layer of the conveyor belt is an elastic pad layer.

[0013] The advantages of this utility model compared to the prior art are: 1. Two V-shaped symmetrically arranged conveyors are used. The conveyor belt is driven to move along the inclined direction by a pushing mechanism, dynamically adjusting the contact position with the workpiece to avoid localized continuous wear. Components such as the back connecting plate and horizontal transmission plate enhance the overall structural integrity of the conveyor belt, preventing folding or deformation during pushing, improving the uniformity of conveyor belt wear, and extending the maintenance cycle.

[0014] 2. The outer side of the conveyor belt is made of wear-resistant material, and an elastic pad is added in the middle layer to ensure wear resistance and provide cushioning elasticity, reduce rigid impact on brittle workpieces, and reduce the workpiece scratch rate; the design of the limit baffle and the back connecting plate further prevents the conveyor belt from denting or warping and reduces the transmission offset.

[0017] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0018] like Figures 1-6 The horizontal conveyor based on synchronous belt shown includes a frame 1, on which two conveyors 2 are symmetrically arranged along the vertical center plane and are arranged in a V-shape. The conveyor belts 3 on the two conveyors 2 respectively conform to both sides of the workpiece for conveying. The conveyor 2 includes a conveyor shaft 4 and a conveyor belt 3. The conveyor shaft 4 is rotatably mounted on the frame 1, and the conveyor belt 3 is drivenly connected to the conveyor shaft 4. The conveyor belt 3 can be displaced along the inclined direction of the conveyor 2. A pushing mechanism 5 is installed on the frame 1 and is drivenly connected to the conveyor belt 3.

[0019] In this scheme, silicon wafers are transported using two V-shaped conveyors 2. The two sides of the silicon wafers are respectively attached to the two sides of the conveyor belt 3 within the conveyor 2. When the conveyor shaft 4 drives the conveyor belt 3 to move, the silicon wafers move forward synchronously, thus achieving horizontal transport. During long-term operation, when the silicon wafers being transported are of uniform size, the contact point between the silicon wafer and the surface of the conveyor belt 3 remains at the same height. Prolonged transport will cause wear at this height on the surface of the conveyor belt 3, thus affecting the accuracy of horizontal transport. This scheme addresses this by incorporating a pushing mechanism 5, which allows the conveyor belt 3 to move along the tilt direction of the conveyor 2. This displacement ensures that the height of the silicon wafers remains constant during horizontal transport, while adjusting the contact position between the conveyor belt 3 and the silicon wafer. This significantly extends the service life of the conveyor belt 3, making the contact with the silicon wafer more uniform and extending the replacement and maintenance cycle. This method largely avoids maintenance and ensures the accuracy of the horizontal transport process.

[0020] In order to realize the displacement function of the conveyor belt 3, the first embodiment of this solution proposes that: the shaft length of the transmission shaft 4 is greater than the width of the transmission belt, the transmission shaft 4 is provided with transmission roller teeth 6, the inner sidewall of the conveyor belt 3 is provided with an inner tooth layer 7, the conveyor belt 3 meshes with the transmission shaft 4, the pushing mechanism 5 is connected to the transmission belt 3 in a transmission connection, and the conveyor belt 3 can be slidably mounted on the frame 1 along the axial direction of the transmission shaft.

[0021] like Figures 1-4 In this embodiment shown, the conveyor belt 3 is directly pushed onto the transmission shaft 4 by the pushing mechanism 5. The entire transmission machine 2 remains stationary; only the position of the transmission belt on the transmission machine 2 is adjusted, thereby achieving the function of switching the contact position between the conveyor belt 3 and the silicon plate. The transmission roller teeth 6 cooperate with the inner tooth layer 7 to achieve stable transmission. Furthermore, since the axis length of the transmission shaft 4 is greater than the width of the conveyor belt 3, the conveyor belt 3 can be displaced along its axial direction on the transmission shaft 4 while still maintaining stable transmission.

[0022] In order to achieve stable transmission of the conveyor belt 3, in this embodiment, the pushing mechanism 5 includes two sets of first linear drivers 8, first transmission frames 9 and horizontal transmission plates 10, each corresponding to one of the two transmission machines 2. The first linear drivers 8 are fixedly installed at the bottom of the frame 1. The output end of the first linear drivers 8 is fixedly connected to the first transmission frame 9. The output direction of the first linear drivers 8 is consistent with the tilt direction of one of the transmission machines 2. Horizontal transmission plates 10 are installed at both the upper and lower ends of each conveyor belt 3 on the side close to or away from the center plane of symmetry. The horizontal transmission plates 10 are all fixedly connected to the first transmission frame 9.

[0023] When the pushing mechanism 5 in this embodiment is working, the first linear driver 8 drives the first transmission frame 9, which is fixedly connected to its output end, to move along the tilt direction of the transmission machine 2. The first transmission frame 9 drives the horizontal transmission plate 10, which is fixedly connected to it, to move synchronously, thereby driving the transmission belt located between the upper and lower horizontal transmission plates 10 to move synchronously, thus realizing the synchronous belt working at the position of the transmission shaft 4.

[0024] To prevent the conveyor belt from warping or folding during the pushing process, which would result in unevenness on its surface and affect the transmission effect, the following structure is designed to solve the above problems: a back connecting plate 11 is provided on the side of the conveyor belt 3 away from the center plane of symmetry. The surface of the back connecting plate 11 is in contact with the surface of the conveyor belt 3. The upper and lower ends of the back connecting plate 11 are fixedly connected to two horizontal transmission plates 10 respectively. Several back connecting plates 11 are provided along the transmission direction.

[0025] The back connecting plate 11 has two functions. The first function is to connect the upper and lower horizontal transmission plates 10, so that the pushing mechanism 5 can synchronously drive the upper and lower horizontal transmission plates 10 to move synchronously, ensuring that the conveyor belt 3 can be driven synchronously when moving upward or downward. The second function is to ensure that the surface of the conveyor belt 3 will not warp or fold when driven by the pushing mechanism 5. It can provide support during pushing and smooth the surface of the conveyor belt 3 after pushing is completed.

[0026] In the second embodiment, the pushing mechanism 5 includes two sets of second linear drivers 12 and a pushing frame 13, each corresponding to one of the two transmitters 2. An inclined guide rail 14 is provided on the frame 1 along the inclined direction of the transmitter 2. The pushing frame 13 is slidably mounted on the frame 1 via the inclined guide rail 14. The second linear driver 12 is fixedly installed below the frame 1. The output end of the second linear driver 12 is fixedly connected to the pushing frame 13. The transmitter 2 is fixedly installed on the pushing frame 13.

[0027] like Figures 5-6 In the second embodiment shown, when the second linear driver 12 is working, it drives the pusher 13 connected to it to move synchronously. The inclined guide rail 14 is used to guide and limit the pusher 13. When the pusher 13 moves, it drives the transmission machine 2 fixedly connected to it to move synchronously, thereby realizing the displacement of the drive conveyor belt 3.

[0028] In order to improve the stability of the conveyor belt 3 when transporting silicon plates, the following structure is designed: each conveyor belt 3 is provided with a limiting baffle 15 in the middle, the limiting baffle 15 is fixedly installed on the frame 1, and the outer wall of the limiting baffle 15 is in contact with the inner wall of the conveyor belt 3.

[0029] By limiting the position of the conveyor belt 3 by the limiting baffle 15, it can be ensured that the conveyor belt 3 will not dent inward when transporting silicon plates, thus ensuring the stability of the transport.

[0030] like Figures 1-6 The outer surface of the conveyor belt 3 shown is made of wear-resistant material 16.

[0031] The wear-resistant material 16 increases the service life of the conveyor belt 3 and reduces the maintenance cycle.

[0032] The middle layer of conveyor belt 3 is an elastic padding layer 17.

[0033] The elastic pad 17 can adapt to the slight warping of the workpiece surface, increasing the contact area between the conveyor belt 3 and the workpiece, reducing local pressure concentration, ensuring transmission stability, and avoiding indentations on the workpiece surface.

[0034] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
