The two sets of mechanisms are placed in parallel, which occupies a large space and causes the equipment to be bloated.

[0014] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] like Figure 1-3 As shown, the embodiment of the utility model includes:

[0016] A half-sheet telescopic film-taking mechanism comprises a bottom mounting plate 1, a channel 2, a telescopic cylinder 3, a connecting member 4, a telescopic plate 5, a variable pitch winding 6, a transmission belt 7, and a motor 8. A channel 2 is opened in the middle of the bottom mounting plate 1, and a telescopic cylinder 3 is arranged below the bottom mounting plate 1 along the line of the channel 2. A cylinder slider 9 on the telescopic cylinder 3 is arranged in the channel 2 and carries a connecting member 4. A telescopic plate 5 is horizontally mounted on the connecting member 4. The front edge of the telescopic plate 5, the side of the connecting member 4, and the front and rear ends of the bottom mounting plate 1 are parallelly provided with left and right variable pitch windings 6 connected by a transmission shaft 10. A transmission belt 7 is tensioned on the variable pitch winding 6, and the transmission shaft 10 is externally connected to a motor 8.

[0017] Among them, the variable pitch winding 6 is composed of a variable pitch pulley 61, a tensioning pulley 62 and a plurality of guide wheels 63. The variable pitch pulley 61 is located on the side of the connecting member 4, the tensioning pulley 62 is located at the rear end of the bottom mounting plate 1, and the guide wheels 63 are located at the front edge of the telescopic plate 5, the front end of the bottom mounting plate 1, and both sides of the tensioning pulley 62.

[0018] Furthermore, pulley brackets 11 are respectively provided at the front and rear ends of the bottom mounting plate 1 , and two sets of variable pitch windings 6 are coaxially provided on both sides of the pulley bracket 11 , both sides of the connecting member 4 , and the front edge of the telescopic plate 5 .

[0019] Furthermore, the connecting members 4 are arranged in pairs on both sides of the telescopic plate 5, a slider 12 is arranged on the outer side of the lower end of the connecting member 4, and slide rails 13 that match the telescopic cylinder 3 in the same direction are arranged on the inner edges of the two edges of the channel 2, and the slider 12 is connected to the slide rail 13.

[0020] This equipment is divided into three parts: bottom fixed part, motor 8 transmission part, and upper telescopic mechanism;

[0021] The telescopic cylinder 3 is installed on the bottom mounting plate 1, the telescopic plate 5 is connected to the cylinder slider 129 through the connecting piece 4, the slider 12 is installed on the side of the connecting piece 4, the bottom mounting plate 1 is provided with a channel 2 to match the telescopic cylinder 3 and the cylinder slider 129, and the slide rails 13 are matched in the same direction at the inner edges of both sides of the channel 2, and the slider 12 and the slide rails 13 are connected to ensure the stability of sliding.

[0022] The motor 8 is mounted on the bottom mounting plate 1 and is connected to a transmission shaft 10 of the motor 8 via a variable pitch winding 6. When the motor 8 rotates, it drives four (2x2) transmission belts 7 to transport photovoltaic silicon wafers.

[0023] The specific working process is that before the flower basket at the front performs the lifting or replacement action, the telescopic cylinder 3 drives the telescopic plate 5 to retract, and the motor 8 does not rotate; when the flower basket is in place, the telescopic cylinder 3 drives the telescopic plate 5 to extend to the bottom of the photovoltaic silicon wafer in the flower basket, and the motor 8 rotates, and the stepping displacement transmission belt 7 preset in the flower basket will dock with the telescopic plate 5, and the two "half slices" on the telescopic plate 5 are synchronously introduced into the flower basket, or the two "half slices" in the flower basket are synchronously exported to the telescopic plate 5 outside the flower basket. When the photovoltaic silicon wafers in the flower basket are emptied or filled, the flower basket is replaced, and the telescopic cylinder 3 drives the telescopic plate 5 to retract, and the above steps are repeated.

[0024] This solution uses one cylinder and one motor 8 to replace the parallel working mode of two sets of equipment, thereby reducing equipment costs; a slider 12 slide rail 13 structure is used to increase the transmission stability of the equipment; this solution simultaneously integrates two variable pitch windings 6, sharing a set of telescopic cylinders 3 and motors 8, greatly reducing the number of parts and components, and facilitating on-site installation, commissioning and subsequent maintenance.

[0025] In the process of automated production of photovoltaic silicon wafers, it is necessary to synchronously import and export two and a half photovoltaic silicon wafers mounted on the same horizontal plane in the flower basket carrier. Half-piece photovoltaic silicon wafers are stored in layers in the flower basket, and two and a half photovoltaic silicon wafers are stored on the same horizontal shelf. Before each material taking device takes materials, the flower basket will lift the photovoltaic silicon wafers to a high position equal to the material taking device to achieve docking. Before the flower basket is lifted, the material taking device needs to retreat and avoid first, and the avoidance process is realized by the telescopic film taking mechanism, i.e., the telescopic plate 5, on the material taking device. When the flower basket is lifted, the telescopic film taking mechanism retracts and avoids. Before the photovoltaic silicon wafer is transferred from the flower basket to the telescopic film taking mechanism, the telescopic film taking mechanism extends into the flower basket to reach the bottom of the photovoltaic silicon wafer to receive the material.

[0026] Considering that a single "half-chip" is small in size, it is easy to cause shaking during expansion and contraction, thereby causing hidden cracks in the silicon chip. In order to solve this technical problem, this solution adopts the method of adding a slide rail 13 and a slider 12 on the side of the expansion and contraction mechanism to ensure the stability of the equipment.

[0027] This solution adopts two-way belt synchronous linkage to achieve synchronous transmission of photovoltaic silicon wafers, which is convenient for installation, commissioning and subsequent maintenance.

[0028] In summary, the utility model provides a half-sheet telescopic sheet taking mechanism, which uses a cylinder to simultaneously control two sets of variable pitch windings 6 for telescoping, and uses a motor 8 for synchronous driving, thereby achieving equipment scale compression, reduction in the number of parts and components, and equipment cost control.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
