[0002] In the field of solar cell manufacturing technology, the transmission of sheet materials (such as silicon wafers or solar cells) is usually essential, which ensures the position conversion of materials in different operation process links between different operation stations. Generally, for the transmission of sheet materials, the available transmission methods include belt transmission, robotic arm handling, etc., and there are also cases where multiple transmission methods are used in combination.

[0003] In the actual operation process, the position accuracy of sheet materials is affected by the transmission process of sheet materials, such as the running accuracy of the transmission equipment itself, the alignment and picking and placing accuracy between different transmission equipment, etc. Therefore, in the actual operation process, it is necessary to set an alignment mechanism in the transmission stroke of sheet materials to adjust the position of the materials, so as to ensure the accuracy of material picking and placing and operation.

[0004] Generally, the alignment adjustment during the conveying process of sheet materials is mainly to set alignment adjustment mechanisms on the lateral sides of the conveying device. For example, in the applicant's prior patent application CN 210635361 U, a centering clamping device is proposed, which can realize the centering clamping of sheet materials and can ensure the lateral position accuracy of sheet materials to a certain extent during the transmission process.

[0048] In the present utility model, the proposed technical solution aims to achieve the four-sided centering adjustment of sheet materials, ensure the consistency and accuracy of the centering adjustment of each sheet material, and thus provide an accurate position basis for the subsequent processing procedures of the sheet materials.

[0049] As follows, with the aid of Figures 1 to 5In the preferred embodiment shown, the technical solutions in the present utility model will be described in detail.

[0050] As an aspect of the present utility model, it provides a four-sided centering mechanism, which includes a substrate 1, a support assembly 2 arranged above the substrate 1, and a centering clamping assembly 3 arranged on the substrate 1.

[0051] Among them, the centering clamping assembly 3 includes a driving unit 301, a driving disk 302, and four centering swing rods 303 respectively arranged around the support assembly 2.

[0052] Specifically, the driving disk 302 is arranged below the support assembly 2 and is coaxially connected to the output shaft of the driving unit 301, so that the driving unit 301 can drive the driving disk 302 to rotate forward and backward respectively; at the same time, four arc-shaped cam grooves 3022 are circumferentially spaced on the disk body of the driving disk 302, and the distances between the two ends (their respective midlines) of each cam groove 3022 and the center of the disk body are different, so that when the component arranged in the cam groove 3022 moves from one end of the cam groove 3022 to the other end, the distance between the component and the center of the disk body continuously changes, thereby realizing the yaw control of the centering swing rod 303.

[0053] More specifically, the four centering swing rods 303 are respectively arranged around the driving disk 302 and are respectively opposite to a cam groove 3022. At the same time, the bottom of the centering swing rod 303 is hinged relative to the substrate 1, its top extends upward to one side of the support assembly 2, and a centering clamping unit 3033 is arranged at the top of the centering swing rod 303.

[0054] In detail, the middle part of the centering swing rod 303 is connected to the cam groove 3022 on its one side through a linkage 304. One end of the linkage 304 is movably connected to the middle part of the centering swing rod 303, and the other end is assembled in the corresponding cam groove 3022 and can reciprocate between the two ends of the cam groove 3022, so that the centering clamping unit 3033 on the centering swing rod 303 can approach or move away from the edge of the support assembly 2 by yawing, thereby clamping or no longer clamping the sheet material on the support assembly 2.

[0055] In the aforementioned four-sided centering mechanism, by rotating the driving disk 302, the positions of the ends of the four linkages 304 in the corresponding cam grooves 3022 can be synchronously changed, and the four centering clamping units 3033 on the four centering swing rods 303 can be driven to swing synchronously, so as to clamp the periphery of the sheet material located on the support assembly 2 or release the clamping of the periphery of the sheet material.

[0056] In actual setting, corresponding to the matching between the driving disk 302 and the output shaft of the driving unit 301, it is preferably provided with a central hole 3021 in the middle thereof, and four cam grooves 3022 are distributed at intervals on the periphery of the central hole 3021 and the output shaft of the driving unit 301 connected to the central hole 3021 at the end.

[0057] Meanwhile, in actual setting, the support assembly 2 can be a fixed platform structure or a transmission mechanism for sheet material transmission.

[0058] For example, in Figure 1 、 Figure 2 In the specific embodiment shown, the support assembly 2 is a conveyor belt assembly for supporting and transporting sheet materials, which includes two conveyor belts 203 arranged in parallel at intervals and a servo motor 201 and a synchronous belt 202 arranged corresponding to the two conveyor belts 203. Among them, at least one end of the two conveyor belts 203 is rotationally assembled through the same support rotating shaft 206, and the output shaft of the servo motor 201 is assembled with the support rotating shaft 206 through the synchronous belt 202. Then, through the operation of the servo motor 201, the support rotating shaft 206 can be driven to rotate, thereby realizing the synchronous movement of the two conveyor belts 203 and completing the transmission of sheet materials on the two conveyor belts 203.

[0059] More preferably, in actual setting, corresponding to the setting of the conveyor belt 203 above the substrate 1, it is preferably provided with a fixing plate 204 vertically on the substrate 1, and the bottom of the fixing plate 204 is installed on the substrate 1. Meanwhile, a profile 205 is provided at the top of the fixing plate 204 to assist in the rotational assembly of each support rotating shaft 206 of the two conveyor belts 203.

[0060] Furthermore, corresponding to the hinge of the centering swing rod 303 on the substrate 1, swing seats 3031 are respectively provided on the substrate 1 corresponding to each centering swing rod 303. In actual setting, the bottom of the swing seat 3031 passes through the substrate 1 and protrudes from the bottom surface of the substrate 1, and the bottom of the centering swing rod 303 is hinged to the bottom of the swing seat 3031, so that the hinged part of the centering swing rod 303 is located below the movable connection part between it and the push rod 3041.

[0061] Through the above settings, a longer swing arm can be obtained within a limited vertical height range. The longer swing arm enables a larger stroke to be obtained with a smaller driving angle; at the same time, by controlling the distance between the hinged part of the centering swing rod 303 and the movable connection part of the push rod 3041, the swing angle of the centering swing rod 303 corresponding to the unit stroke distance of the sliding seat 3043 can be adjusted accordingly, and then the swing amplitude of the centering swing rod 303 can be adjusted as needed.

[0062] As another embodiment, swing seats 3031 are respectively arranged on the substrate 1 corresponding to each pair of centering swing rods 303, and the centering swing rods 303 are hinged on the swing seats 3031; a baffle 3035 is further arranged on the swing seats 3031, which is arranged between the centering swing rods 303 and the support assembly 2 and is used for clamping and swinging limit of the centering swing rods 303 to avoid excessive clamping of the sheet material by the centering swing rods 303.

[0063] In addition, in a preferred embodiment, for the centering clamping unit 3033 arranged at the top of the centering swing rod 303, it preferably includes a plurality of guide wheels arranged at intervals in the direction parallel to the edge of the sheet material to be clamped, and the centering swing rod 303 contacts the edge of the sheet material through the plurality of guide wheels to complete centering adjustment.

[0064] Furthermore, for the four-sided centering mechanism in the preferred embodiment, the swing control of the centering swing rod 303 mainly depends on the assembly among the centering swing rod 303, the linkage 304 and the driving disk 302. Among them, the cam groove 3022 on the driving disk 302 is the basis for the assembly connection of the three. Due to its arc-shaped structure and the continuous change of the distance between the center line of the groove and the center of the disk body, the centering swing rod 303 has the ability to reciprocally yaw under the drive of the linkage 304.

[0065] In actual setting, the cam groove 3022 in the preferred embodiment is an Archimedean spiral, a modified sine curve or a modified trapezoidal curve.

[0066] More specifically, in a preferred embodiment, the linkage 304 includes a push rod 3041, a linear slide rail 3042, a sliding seat 3043 and a cam follower 3044. Among them, the linear slide rail 3042 is arranged between the centering swing rod 303 and the driving disk 302, and the sliding seat 3043 is slidably assembled on the linear slide rail 3042 and can perform reciprocating motion under the guidance of the linear slide rail 3042. At the same time, the bottom of the cam follower 3044 in the preferred embodiment is embedded in the cam groove 3022, and its top is connected to one end of the sliding seat 3043. With such a setting, the rotation of the driving disk 302 can drive the cam follower 3044 to reciprocate radially along the disk body of the driving disk 302, and further drive the sliding seat 3043 to reciprocate and translate radially along the disk body.

[0067] Correspondingly, a waist-shaped hole 3032 is opened in the middle of the centering swing rod 303 along its length direction. One end of the aforementioned push rod 3041 is connected to the sliding seat 3043, and the other end is movably connected to the waist-shaped hole 3032, so that the assembly position of the end of the push rod 3041 and the waist-shaped hole 3032 can reciprocally change following the movement of the sliding seat 3043, thereby realizing the yaw control of the centering swing rod 303.

[0068] With the above settings, the movement of the cam follower 3044 in the cam groove 3022 can be converted into the sliding of the sliding seat 3043 on the linear slide rail 3042 and the displacement movement of the end of the push rod 3041 in the waist-shaped hole 3032, and further into the swinging of the centering swing rod 303.

[0069] More specifically, in the preferred embodiment, the embedding depth of the push rod 3041 in the sliding seat 3043 is adjustable, so that it can be applied to the clamping of different-sized sheet materials (such as battery sheets), and stepless adjustment can be achieved within a certain range.

[0070] During actual setting, as Figure 5 shown, corresponding to the installation of the push rod 3041 on the sliding seat 3043, an installation hole 3045 with a certain length is provided in the sliding seat 3043. The axis of the installation hole 3045 is further preferably parallel to the length direction of the sliding seat 3043 (i.e., Figure 1 the horizontal direction parallel to the substrate 1 in ). At the same time, a locking hole 3046 is provided on the outer periphery of the sliding seat 3043 in the radial direction of the installation hole 3045. The locking hole 3046 penetrates through the outer surface of the sliding seat and communicates with the installation hole 3045. One end of the push rod 3041 is coaxially embedded in the installation hole 3045 and faces the locking hole 3046 with its outer peripheral wall, and a locking member with an end abutting against the outer peripheral wall of the push rod 3041 is fixedly connected in the locking hole 3046. The fixed connection between the push rod 3041 and the sliding seat 3043 is realized through the setting of the locking member. Among them, the locking member can preferably be a screw, a pin, etc.

[0071] In addition, corresponding to the adjustable connection part between the push rod 3041 and the sliding seat 3043, the connection position of the swinging seat 3031 on the substrate 1 is set to be adjustable. Specifically, as Figure 2 shown, preferably a waist-shaped installation hole 3047 with a length direction parallel to the sliding direction of the sliding seat 3043 is provided on the swinging seat 3031, so that the fixed position of the swinging seat 3031 on the substrate 1 can be changed by changing the fixed position of the connection bolt in the waist-shaped installation hole 3047, and further change the relative position between the hinged part of the centering swing rod 303 and the driving disk 302, and adjust the distance between the centering clamping unit 3033 of the centering swing rod 303 and the center of the driving disk 302 when the centering swing rod 303 is in the vertical state.

[0072] It can be understood that the linkage 304 in the preferred embodiment can be set in other forms besides the above form, as long as it can meet the yaw control of the centering swing rod 303.

[0073] Preferably, in order to better achieve the circumferential limit of the push rod 3041, it is preferred to axially provide a locking groove with a certain depth along the outer periphery of one end of the push rod 3041 for connecting the sliding seat 3043, so that the locking member for locking the push rod 3041 is embedded and abutted against the locking groove at its end.

[0074] In another preferred embodiment, a connecting rod is provided between the centering swing rod 303 and the cam groove 3022. One end of the connecting rod is hinged to the middle of the centering swing rod 303, and the other end is hinged to the slider slidably assembled in the cam groove 3022. By the sliding of the slider between the two ends of the cam groove 3022 and the corresponding rotation of both ends of the connecting rod, the yaw control of the centering swing rod 303 can also be achieved. The difference from the above embodiment is that when using a connecting rod, there is no need to axially provide a waist-shaped hole 3032 in the middle of the centering swing rod 303 along its length direction.

[0075] Through the above settings, the preferred embodiments as shown in Figure 1 , Figure 2 can be obtained. By using the rotation control of the drive disk 302 in the preferred embodiment, four centering swing rods 303 can be correspondingly driven to swing synchronously, so as to complete the four-sided centering adjustment of the sheet material on the support assembly 2.

[0076] As another aspect of the present invention, the present application also proposes a material handling device, including the aforementioned four-sided centering mechanism, and further including a belt conveying assembly, a handling assembly and a workbench. The support assembly 2 is a conveyor belt assembly, which can complete the processes of pre-conveying, four-sided centering and post-centering handling of the sheet material to the workbench. The belt conveying assembly is arranged on one side of the support assembly 2, and the belt conveying assembly is used to convey the sheet material to be centered to the support assembly.

[0077] Specifically, the belt conveying assembly is arranged upstream of the conveyor belt assembly, the workbench is arranged downstream of the conveyor belt assembly. At the same time, a handling mechanism is also arranged above the workbench and the conveyor belt assembly to realize the picking and handling of the sheet material after the four-sided centering adjustment.

[0078] During actual work, the sheet material to be centered (such as a battery sheet) is conveyed by the belt conveying assembly to the conveyor belt assembly, and the four sides of the sheet material on the conveyor belt assembly are aligned by the four-sided centering mechanism to achieve the positioning of the sheet material. After the positioning is completed, the handling assembly picks up the material from the conveyor belt assembly and transports it to the workbench for subsequent processing procedures of the sheet material.

[0079] In a preferred embodiment, the handling component is arranged above the workbench and the support component 2, and includes a displacement unit and a suction cup unit arranged on the displacement unit. The displacement unit is used to drive the suction cup unit to move back and forth between the workbench and the support component to directly transfer the centered sheet-like material to the workbench. Among them, the suction cup unit can be vertically aligned with the workbench and the support component 2 respectively under the drive of the displacement unit, that is, it can be vertically aligned with the centering station and the subsequent stations respectively. In this way, the suction cup unit can adsorb and transport the sheet-like material that has completed the four-sided centering operation to the subsequent station (i.e., the workbench).

[0080] For the four-sided centering mechanism, it is preferably in a vertical state when clamping, that is, the height change of the outermost edge of the guide wheel can be regarded as gradually increasing. In this way, when the suction cup assembly is used for the material taking measure of air extraction, it only needs to be slightly higher than the high point to directly take the material without avoiding.

[0081] It is not difficult to understand that during actual operation, when the sheet-like material (such as a battery cell) has not been conveyed onto the conveyor belt assembly, the tops of the four centering swing rods 303 should be lowered by yawing to a position lower than the height of the conveyor belt 203 to avoid affecting the conveyance of the sheet-like material. After the sheet-like material is conveyed in place, the four centering swing rods 303 (towards the center of the sheet-like material and the direction of upward movement) rotate to a position where they can center and clamp, thereby completing the four-sided centering adjustment of the sheet-like material.

[0082] By using the combined setting of the conveyor belt assembly, conveyor belt, workbench, and handling mechanism in the four-sided centering mechanism, the feeding, centering adjustment, and feeding to the subsequent station of the sheet-like material can be quickly realized. The number of handling times in the whole process is small, the equipment structure is compact, and the positioning accuracy of the sheet-like material in the subsequent processing process can be fully guaranteed.

[0083] More specifically, in the preferred embodiment, the centering swing rod 303 arranged between the support component 2 and the belt conveyor component includes a swing rod arranged horizontally below the belt conveyor component and two support rods 3034 extending vertically at both ends of the swing rod; the tops of the two support rods 3034 are respectively provided with centering clamping units 3033, and the two centering clamping units 3033 can be respectively arranged on the transverse sides of the end of the feeding component when the centering swing rod 303 swings to the clamping position. At this time, the centering swing rod 303 provided with the two support rods 3034 uses the centering clamping units 3033 at both ends of its top to complete the centering clamping of this side of the sheet-like material. By using the special design of the aforementioned centering swing rod 303, the distance between the conveyor belt assembly and the conveyor belt can be effectively avoided from being too large, ensuring the accuracy of the transmission of the sheet-like material between the conveyor belt assembly and the conveyor belt.

[0084] The four-sided centering mechanism in the present utility model has a compact structure and convenient control. It can effectively achieve the four-sided centering and clamping of sheet materials, improve the alignment accuracy during the processing of sheet materials, and ensure the consistency and accuracy of the centering adjustment of batch materials, providing guarantee for the processing accuracy of sheet materials and even subsequent solar cell modules, and having good practical value.

[0085] Those skilled in the art can easily understand that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
