Description

Technical Field

[0001] This utility model relates to the field of automation technology for high-temperature processes of solar cells, and in particular to a quartz boat handling device. Background Technology

[0002] In the field of high-temperature process automation technology, gantry-type quartz boat handling mechanisms are currently widely used for transporting quartz boats. However, the fixed grippers of current automated gantry-type quartz boat handling mechanisms have a triangular contact position with the quartz boat, resulting in line contact between the grippers and the boat. This makes the boat prone to movement during handling, causing positional errors and leading to inconsistent boat placement and numerous gripper alarms. According to machine tracking and anti-pressure alarm data, the number of alarms can reach 20+ per shift. After an alarm, the boat must be reset to clear the alarm. If the alarm cannot be cleared, manual intervention is required to straighten the boat's position so that handling can continue. This not only easily damages the silicon wafers but also significantly impacts production efficiency, increasing time, labor, and material costs.

[0003] Therefore, it is necessary to design a quartz boat transport device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a quartz boat handling device that overcomes the defect of inaccurate boat placement and retrieval, and improves the accuracy and efficiency of placement and retrieval.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quartz boat handling device for handling quartz boats, comprising a mounting base and two gripper mechanisms disposed opposite to each other below the mounting base. Each gripper mechanism includes a horizontal support plate, a guide component disposed above the horizontal support plate, a horizontal drive cylinder disposed below the horizontal support plate, a vertical support plate, and at least two gripper fixing blocks disposed on one side of the vertical support plate. The guide component is located between the horizontal support plate and the mounting base. The output end of the horizontal drive cylinder is connected to the mounting base. The horizontal drive cylinders of the two gripper mechanisms respectively drive the opposite gripper fixing blocks closer to or further away from each other. The end face of the gripper fixing block that contacts the groove bar of the quartz boat is an arc surface.

[0006] As a further improvement of this utility model, the arc of the arc surface of the gripper fixing block is 90°≤α≤180°.

[0007] As a further improvement to this utility model, the radius R of the arc surface of the gripper fixing block and the radius r of the grooved bar satisfy the relationship: R = k×r, where 1.0 <k≤1.2。

[0008] As a further improvement of the present invention, the gripper mechanism further includes a vertical drive cylinder and a support plate disposed on a vertical support plate. The output shaft of the vertical drive cylinder is provided with a clamping plate that cooperates with the support plate. The vertical drive cylinder drives the clamping plate to move up and down above the support plate.

[0009] As a further improvement of this utility model, a guide rod is provided above the pallet, and a guide channel that cooperates with the guide rod is provided on the vertical support plate.

[0010] As a further improvement of the present invention, the mounting base includes a horizontal plate and a vertical plate located in the middle of the lower part of the horizontal plate. The two horizontal drive cylinders of the gripper mechanism are located on both sides of the vertical plate, and the output shaft of the horizontal drive cylinder is connected to the vertical plate.

[0011] As a further improvement of this utility model, a protective plate is provided on one side of the vertical support plate. The protective plate is located below the horizontal drive cylinder, and a buffer block is provided on the lower surface of the protective plate.

[0012] As a further improvement of the present invention, the invention also includes a machine base and a lifting mechanism disposed on the machine base, wherein the mounting base moves up and down under the drive of the lifting mechanism.

[0013] As can be seen from the above technical solution, the grippers of the quartz boat handling device of this utility model form surface contact with the cylindrical grooved bar. Compared with the line contact of the prior art, this increases the contact area and friction, eliminating the risk of slippage during clamping. The arc-shaped design has an automatic centering and guiding effect on the grooved bar. Even if there is a slight deviation in the initial position, it can be automatically corrected to the center position during clamping, eliminating error problems and achieving precise positioning. Therefore, compared with the prior art, the grippers are more accurately fixed in position when handling the boat, avoiding differences in position each time, thus better protecting the quartz boat, reducing repeated alarms, reducing the error of the boat handling position to within ±1 mm, reducing the number of alarms to 2 per shift, and reducing the damage rate of the quartz boat by 80%.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Please refer to Figure 1 and Figure 2 As shown, this utility model provides a quartz boat transporting device for transporting quartz boats 100. The quartz boat transporting device includes a machine base (not shown), a lifting mechanism 10 mounted on the machine base, a mounting plate 20 mounted on the lifting mechanism 10, two mounting seats 30 located below the mounting plate 20, and two gripper mechanisms 40 located opposite each mounting seat 30. The mounting seats 30 move up and down under the drive of the lifting mechanism 20. In this embodiment, the quartz boat transporting device can transport two quartz boats simultaneously. In other embodiments, the number of mounting seats 30 and the number of gripper mechanisms 40 mounted on them can be set as needed, and is not limited here. The quartz boat 100 specifically includes a top plate, a bottom plate, four grooved bars 101 connecting the top plate and the bottom plate, and two boat ears 102 on both sides.

[0021] Please refer to Figure 2 As shown, two gripper mechanisms 40 below the mounting base 30 are arranged opposite each other to grip and transport the quartz boat. The two gripper mechanisms 40 have the same structure and are symmetrically arranged. Specifically, the gripper mechanism 40 includes a horizontal support plate 41, a guide assembly 43 above the horizontal support plate 41, a horizontal drive cylinder 44 below the horizontal support plate 41, a vertical support plate 42, and at least two gripper fixing blocks 46 on one side of the vertical support plate 42. The output end of the horizontal drive cylinder 44 is connected to the mounting base 30. The mounting base 30 includes a horizontal plate 31 and a vertical plate 32 located in the middle below the horizontal plate 31. The horizontal drive cylinders 44 of the two gripper mechanisms 40 are located on both sides of the vertical plate 32, and the output shafts of the horizontal drive cylinders 44 are connected to the vertical plate 32.

[0022] The guide assembly 43 is located between the horizontal support plate 41 and the mounting base 30, and can be selected as a guide form with a slide rail and a slide groove, which is not limited here. The horizontal drive cylinders 44 of the two gripper mechanisms 40 respectively drive the opposite horizontal support plate 41, vertical support plate 42 and the gripper fixing blocks 46 on it to move closer or further away. Preferably, the two gripper fixing blocks 46 on the same vertical support plate 42 are mounted on the vertical support plate 42 by a fixing bracket 45.

[0023] Please refer to Figures 3-5As shown, the end face of the clamping jaw fixing block 46 that contacts the groove bar 101 is a circular arc surface 461. The radian α of the circular arc surface 461 satisfies 90°≤α≤180°, and the height h is greater than the diameter of the groove bar 101. The radius R of the circular arc surface 461 and the radius r of the groove bar satisfy the relational expression: R = k×r, where 1.0<k≤1.2. With such arrangement, the radius of the circular arc surface is slightly larger than the radius of the groove bar, creating a wrapping effect that makes clamping more stable.

[0024] The clamping jaw mechanism 40 further includes a vertical drive cylinder 47 and a support plate 48 disposed on the vertical support plate 42. The output shaft of the vertical drive cylinder 47 is provided with a clamping plate that cooperates with the support plate 48, and the vertical drive cylinder 47 drives the clamping plate to move up and down above the support plate 48. During handling, the support plate 48 is located below the boat ear 102 of the quartz boat, the vertical drive cylinder 47 drives the clamping plate to abut against above the boat ear 102, and the clamping plate cooperates with the support plate 48 to clamp the boat ear 102, so as to fix the quartz boat in the vertical direction.

[0025] One side of the vertical support plate 42 is further provided with a protection plate 49, which is located below the horizontal drive cylinder 44, and is used to isolate the horizontal drive cylinder 44 and accessories such as the air pipe connected to the cylinder from the quartz boat below. The lower surface of the protection plate 49 is provided with a buffer block 491, which is used to buffer the upward impact force of the quartz boat.
