Description

Technical Field

[0001] This utility model belongs to the field of silicon rod size detection technology, and in particular relates to a silicon rod size detection clamping device. Background Technology

[0002] Silicon rods, especially monocrystalline silicon rods, are the core raw material for manufacturing solar photovoltaic cells. Their quality directly determines the quality of subsequent silicon wafers and the power generation efficiency of the final photovoltaic modules. In recent years, driven by the global goal of "carbon neutrality," the photovoltaic industry has experienced explosive growth, leading to a surge in demand for upstream silicon materials. This has also placed unprecedented demands on production efficiency and product quality. Against this backdrop, silicon rod production must evolve towards greater efficiency, precision, and automation. The traditional model of quality control relying on manual experience and simple tools has become a bottleneck for improving production capacity and yield. Therefore, dimensional inspection technology that enables automated, high-precision, and non-contact measurement has become an indispensable part of the silicon rod production process.

[0003] Silicon rods need to be kept stable and centered during dimensional inspection. Traditional clamping methods easily cause the silicon rod to shift or wobble, affecting the inspection accuracy. Furthermore, since the bottom of the silicon rod is in contact with the support structure, it needs to be lifted for each measurement, significantly impacting measurement efficiency. Therefore, we provide a silicon rod dimensional inspection clamping device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a silicon rod size detection clamping device. The device uses an electric lifting cylinder to control the up and down movement of the diagonal plate, which works in conjunction with the roller assembly to accurately and quickly clamp and position the silicon rod. At the same time, the two roller assemblies support the silicon rod, suspending it above the detection port, so that the silicon rod at the detection port can be quickly measured, thus improving measurement efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a silicon rod size detection clamping device, including a base plate; an inverted U-shaped frame is fixed on the upper end surface of the base plate, an electric lifting cylinder is fixed on the upper end surface of the outer side of the inverted U-shaped frame, an adjustment plate is provided on the inner side of the inverted U-shaped frame, a diagonal plate is provided at the position directly below the adjustment plate, and two sets of rollers are provided on the upper end surface of the base plate in a symmetrical arrangement, one set of rollers being located directly below the diagonal plate.

[0006] The present invention is further configured such that a detection port is provided on the upper surface of the adjustment plate located between the two sets of rollers, and the detection port penetrates through the side of the base plate.

[0007] The present invention is further configured such that L-shaped plates are provided at both ends of the roller assembly, the shafts at both ends of the roller assembly are rotatably connected to the side walls of the L-shaped plates, and the L-shaped plates are installed on the upper end face of the base plate by bolts.

[0008] The present invention is further configured such that adjustment ports are provided at both the front and rear parts of the upper surface of the adjustment plate, and the two sets of adjustment ports penetrate through the lower surface of the adjustment plate.

[0009] The present invention is further configured such that a sliding column is fixed at the position of the two sets of adjustment ports in the middle of the upper wall of the diagonal plate, and a square plate that abuts against the upper surface of the adjustment plate is fixed at the upper end of the sliding column through the adjustment port. The piston end of the electric lifting cylinder passes through the upper end of the inverted U-shaped frame, and the piston end of the electric lifting cylinder is bolted to the upper surface of the adjustment plate located between the two sets of adjustment ports.

[0010] The present invention is further configured such that each of the inclined surfaces at both ends of the diagonal plate is provided with a ball opening, and there are multiple ball openings.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1 Please see Figures 1 to 5 This utility model is a silicon rod size detection clamping device. The diagonal plate 202 is moved up and down by an electric lifting cylinder 2 and works in conjunction with the roller group 3 to clamp the silicon rod accurately and quickly and position it. At the same time, the two roller groups 3 support the silicon rod so that it is suspended above the detection port 102, so that the silicon rod at the detection port 102 can be quickly measured, thus improving the measurement efficiency.

[0022] Specifically, the base plate 1 has an inverted U-shaped frame 101 fixed to its upper surface. An electric lifting cylinder 2 is fixed to the upper surface of the inverted U-shaped frame 101. An adjustment plate 201 is located inside the inverted U-shaped frame 101. A diagonal plate 202 is located directly below the adjustment plate 201. Two sets of roller groups 3 are symmetrically arranged on the upper surface of the base plate 1. One set of roller groups 3 is located directly below the diagonal plate 202. A detection port 102 is opened on the upper surface of the adjustment plate 201 between the two sets of roller groups 3, and the detection port 102 penetrates the side of the base plate 1. L-shaped plates 301 are provided at both ends of the roller groups 3. The shafts at both ends of the roller groups 3 are rotatably connected to the side walls of the L-shaped plates 301. The L-shaped plates 301 are installed on the upper surface of the base plate 1 by bolts.

[0023] The operation process of this embodiment is as follows: When the silicon rod needs to be clamped for size detection using the above structure, the silicon rod is placed from directly below the diagonal plate 202, so that one end of the silicon rod initially rests on the roller group 3, and the electric lifting cylinder 2 is controlled to work. The electric lifting cylinder 2 directly controls the diagonal plate 202 to move downward, so that the diagonal plate 202 clamps the upper part of the silicon rod, thereby positioning the silicon rod. Then, the silicon rod is pushed to slide on the roller group 3, so that one end of the silicon rod moves to another roller group 3, thereby placing the middle part of the silicon rod at the detection port 102. At this time, the silicon rod at the detection port 102 can be measured by the detection equipment. With the support of the two roller groups 3, the bottom position of the silicon rod at the detection port 102 will not be in contact with the external structure, which facilitates accurate and rapid detection of the silicon rod's size.

[0024] Example 2 Please see Figure 4 and Figure 5 Based on Example 1, by adjusting the cooperation between the adjustment plate 201 and the diagonal plate 202, the position of the silicon rod located at the detection port 102 can be easily adjusted.

[0025] Specifically, adjustment ports 207 are provided at the front and rear of the upper surface of the adjustment plate 201, and the two sets of adjustment ports 207 pass through the lower surface of the adjustment plate 201. A sliding column 204 is fixed at the middle of the upper surface of the diagonal plate 202 corresponding to the position of the two sets of adjustment ports 207. The sliding column 204 passes through the upper surface of the adjustment port 207 and a square plate 205 is fixed thereto, which abuts against the upper surface of the adjustment plate 201. The piston end of the electric lifting cylinder 2 passes through the upper surface of the inverted U-shaped frame 101, and the piston end of the electric lifting cylinder 2 is bolted to the upper surface of the adjustment plate 201 located between the two sets of adjustment ports 207.

[0026] The operation process of this embodiment is as follows: With the above structure, when it is necessary to adjust the position of the silicon rod at the detection port 102, the silicon rod can be controlled to rotate on the roller group 3, so that the silicon rod can move left and right on the roller group 3. At the same time, the diagonal plate 202 can be controlled to slide along the lower end face of the adjustment plate 201, so that the diagonal plate 202 will drive the sliding column 204 to move in the adjustment port 207, and drive the square plate 205 to slide on the upper end face of the adjustment plate 201. By the square plate 205 being above the adjustment plate 201, the diagonal plate 202 is limited, ensuring that the diagonal plate 202 is stably located below the adjustment plate 201.

[0027] Example 3 Please see Figure 4 Based on Example 1, the use of ball block 206 can reduce the friction on the silicon rod and prevent damage to the surface of the silicon rod.

[0028] Specifically, the inclined surfaces at both ends of the diagonal plate 202 are provided with ball openings 203, and there are multiple ball openings 203. The multiple ball openings 203 on the inclined surfaces at both ends of the diagonal plate 202 are distributed linearly and equidistantly. Each ball opening 203 has a ball block 206 rotatably arranged inside it.

[0029] The operation process of this embodiment is as follows: When the control diagonal plate 202 clamps the silicon rod, the ball block 206 on the two inclined surfaces of the diagonal plate 202 will abut against the surface wall of the silicon rod. Therefore, when the control silicon rod moves on the roller group 3, the silicon rod will drive the ball block 206 to rotate in the ball opening 203. Thus, the rotation of the ball block 206 can reduce the friction on the silicon rod and avoid damage to the surface wall of the silicon rod.
