Description

TECHNICAL FIELD

[0001] The present application relates to the field of solar cell processing, in particular to a horizontal conveying device of a graphite box assembly suitable for use in an automatic storage system. BACKGROUND

[0002] Copper-indium-gallium-selenium solar cells have the advantages of good stability, radiation resistance, good performance, low cost, high efficiency, etc. With the continuous development of the technology, the market share of copper-indium-gallium-selenium solar cells in the photovoltaic market continues to rise, and they have strong competitiveness compared with traditional crystalline silicon cells. With the gradual expansion of the scale of the photovoltaic industry, especially the rapid growth of the output of thin-film solar cells in recent years.

[0003] The graphite box assembly of copper-indium-gallium-selenium solar cells is an intermediate product of copper-indium-gallium-selenium solar cells. The storage system of the graphite box assembly of copper-indium-gallium-selenium solar cells is an adjustable buffer area in the production line layout, so the utilization rate of the graphite box assembly storage system will affect the production efficiency of the entire production line.

[0004] The graphite box assembly of copper-indium-gallium-selenium solar cells is sensitive to mechanical strain and vibration, and measures need to be taken during transportation to ensure stability and no vibration during transportation. In the prior art, general horizontal conveying devices will produce vibration during mechanical transportation and placement, which will affect the performance of the graphite box assembly, so during the process of placing the graphite box assembly into the storage device, the operator is required to carefully place the graphite box assembly into the storage device. Since the storage system of the graphite box assembly is an adjustable buffer area in the production line layout, the utilization rate of the graphite box assembly storage system will affect the production efficiency of the entire production line. The non-automatic access mode of the graphite box assembly seriously affects the production efficiency of the entire production line. SUMMARY

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present application is at least to provide a horizontal conveying device of a graphite box assembly to achieve smooth horizontal conveying of the graphite box assembly.

[0006] To achieve the above-mentioned purposes and other related purposes, one embodiment of the present application provides a horizontal conveying device of a graphite box assembly,

[0007] including a support platform assembly and a horizontal conveying component;

[0008] The support platform assembly includes two horizontally arranged longitudinal support rods for supporting the graphite box assembly, and a support platform transverse link fixed below the longitudinal support rods;

[0009] The horizontal conveying component is provided on the support platform transverse link and includes a push plate assembly for pushing the graphite box assembly and a gripper assembly for clamping the graphite box assembly.

[0010] In some embodiments of the present application, the horizontal conveying component further comprises a horizontal conveyor belt provided on the table assembly, and the push plate assembly and the gripper assembly are fixed on the horizontal conveyor belt by the operation table. Through the arrangement of the push plate assembly, automatic storage of the table assembly can be realized, and through the arrangement of the gripper assembly, automatic clamping of the table assembly can be realized.

[0011] The operation table comprises a fixed plate provided on the horizontal conveyor belt, one side of the fixed plate is provided with the push plate assembly, and the other side of the fixed plate is provided with the gripper assembly. The push plate assembly and the gripper assembly are both fixed on the horizontal conveyor belt by the operation table, and the structure is simple and convenient.

[0012] The push plate assembly comprises a push plate lifting oil cylinder fixedly connected to one side of the fixed plate, and a push plate is arranged at the end of the piston rod of the push plate lifting oil cylinder. When the push plate is in a low position, the top end of the push plate assembly is lower than the position of the longitudinal supporting rod. When the push plate is in a high position, at least part of the push plate is higher than the position of the longitudinal supporting rod. When the push plate is in the low position, the top end of the push plate assembly is lower than the position of the longitudinal supporting rod, so that the graphite box assembly can be conveniently pushed horizontally on the longitudinal supporting rod. When the push plate is in the high position, the push plate can push the graphite box assembly.

[0013] The gripper assembly comprises a gripper lifting oil cylinder and a gripper. The gripper lifting oil cylinder is fixedly connected to the other side of the fixed plate, and the end of the piston rod of the gripper lifting oil cylinder is connected to the gripper through a gripper connecting component. When the gripper is in a low position, the top end of the gripper assembly is lower than the position of the supporting rod. When the gripper is used to clamp the graphite box assembly, the gripper is in a high position. When the gripper assembly is in the low position, it is below the table assembly, so that it can be conveniently moved below the table assembly.

[0014] The clamping surfaces of the upper and lower clamping heads of the gripper are provided with a polyurethane layer, which can effectively protect the graphite box assembly.

[0015] The gripper connecting component comprises an upper horizontal plate, a side plate and a lower horizontal plate. The upper horizontal plate is fixedly connected to the movable end of the gripper lifting oil cylinder. The side plate is fixedly connected to the side end of the upper horizontal plate. The lower horizontal plate is arranged at the bottom end of the side plate, and an adjusting cylinder is arranged on the lower horizontal plate. The movable end of the adjusting cylinder is fixedly connected to the gripper. Through the specific arrangement of the gripper connecting component, the graphite box assembly can be accurately clamped. Before clamping, the gripper can be more accurately aligned with the graphite box assembly through the adjusting cylinder, and the distance between the upper and lower clamping heads is slightly greater than the thickness of the graphite box assembly. When preparing to clamp, the cylinder piston rod of the adjusting cylinder is retracted, the upper clamping head naturally falls on the upper surface of the graphite box assembly by gravity, and the gripper operates to tighten the upper and lower clamping heads to clamp the graphite box assembly.

[0016] The inner side of the longitudinal supporting rod is provided with an axially horizontally arranged bearing wheel, the rolling direction of which is consistent with the conveying direction of the graphite box assembly, and the bearing wheel is composed of a polyurethane rubber wheel with a bearing skeleton to match the conveying of the copper-indium-gallium-selenium solar cell by the conveying component and avoid vibration during conveying.

[0017] The bottom end of the graphite box assembly is provided with a sunken body, the width of which is equal to the distance between the two rows of bearing wheels, and when the graphite box assembly is placed on the bearing wheels, the two side walls of the sunken body abut against the inner sides of the two rows of bearing wheels, thereby playing a role of positioning the position of the graphite box assembly.

[0018] The top of the longitudinal supporting rod is provided with an axially vertically arranged lateral guide wheel, the rolling direction of which is consistent with the conveying direction of the graphite box assembly. The lateral guide wheel is composed of a polyurethane rubber wheel with a bearing skeleton to match the conveying of the copper-indium-gallium-selenium solar cell by the conveying component and play a guiding role on the graphite box assembly, and the lateral vibration of the copper-indium-gallium-selenium solar cell during conveying is absorbed by the polyurethane.

[0019] A limiting mechanism for blocking the further forward movement of the clamping jaw assembly and the push plate assembly is arranged on the lateral connecting component near the storage component, and the limiting mechanism comprises a limiting lifting cylinder arranged on the lateral connecting component, and a blocking wheel arranged at the top end of the limiting lifting cylinder. This avoids accidents caused by the further forward movement of the clamping jaw assembly and the push plate assembly. The horizontal conveying component has high action accuracy and can meet the sensitive characteristics of the assembly itself.

[0020] The horizontal conveying component further comprises a straight line bearing member arranged on the lateral connecting components of the supporting table assembly, and the two ends of the lateral connecting component are fixedly connected with the two opposite longitudinal supporting rods through vertical connecting rods, so that the lateral connecting component as a whole is below the longitudinal supporting rods. At this time, the horizontal conveying component is arranged on the lateral connecting component, so that the horizontal conveying component as a whole is below the longitudinal supporting rods, thereby facilitating the horizontal pushing of the supporting table assembly.

[0021] The horizontal conveying component further comprises a horizontal driving motor arranged at one end of the straight line bearing member near the storage component. The initial positions of the push plate assembly and the clamping jaw assembly are away from the storage component, and the horizontal driving motor is arranged near the storage component, so that the structure has better stress performance and stronger overall stability.

[0022] The lateral connecting component is further provided with a drag chain matched with the straight line bearing member. The equipment such as the wire pipeline related to the clamping jaw assembly and the push plate assembly can be conveniently and safely arranged.

[0135] The conveying method of the horizontal conveying device is as follows:

[0136] For the case of pushing the graphite box assembly to the storage position, the steps are as follows:

[0137] The height of the push plate piston rod is adjusted by the push plate lifting oil cylinder, so that the height of the push plate matches the height of the graphite box assembly;

[0138] The upper side of the horizontal drive motor drives the belt body to move inward, and the horizontal conveying belt drives the operation table and the push plate to move inward, and the push plate pushes the graphite box assembly to move towards the storage position. When the graphite box assembly is pushed to the storage position by the push plate, the horizontal drive motor drives the upper side of the horizontal conveying belt to move outward, and drives the operation table and the push plate to return to the initial position on the outside;

[0139] The height of the push plate piston rod is adjusted to the initial position, so that the height of the push plate is lower than the height of the longitudinal supporting rod;
