Description

Technical Field

[0001] The present disclosure relates to the technical field of photovoltaic component transmission and transportation, and specifically provides a transfer mechanism. Background Art

[0002] In the new energy industry such as hot wire CVD or other photovoltaic production lines, the transport transfer mechanism is widely used in the automated production line. In the photovoltaic industry, the transport transfer carrier transfer mechanism is particularly important. The transport transfer carrier transfer mechanism requires stable transmission, high transmission accuracy, large transmission volume, and fast speed during transportation. The impact of ambient temperature changes on the size changes of the transport transfer mechanism has become a key issue for the equipment.

[0003] In the photovoltaic industry, the transport carrier transplanting mechanism currently belongs to the single-warehouse transport on the market, but this method usually has the disadvantages of long transport cycle, insufficient carrying capacity, single transport distance, and the influence of ambient temperature changes on the size change of the transport carrier transplanting mechanism. Summary of the invention

[0004] In order to solve the problems existing in the above-mentioned prior art, the present invention provides a transfer mechanism, which uses a single loading unit or a multi-loading unit reciprocating transmission and transfer transport structure to achieve transportation, and can adjust the unloading and transportation position according to different transportation distances, thereby meeting its functionality, effectively shortening the transmission time and production cycle, and avoiding the impact of changes in ambient temperature on the size of the transmission and transfer mechanism. That is, the present invention provides a transfer mechanism for a multi-bin transport carrier that is not affected by changes in ambient temperature and can freely change the distance.

[0005] In a first aspect, some embodiments of the present invention provide a transfer mechanism, comprising: a base, which is mounted and fixed on the ground; at least one loading part, which is located on the upper surface of the base and is used to load materials; at least one first driving part, which is the same in number as the loading parts and is installed at the lower part of the loading part, and can make the loading part move back and forth linearly on the upper surface of the base; and at least one thermal expansion variable distance part, which is installed below the loading part and can change distance according to the temperature change of the loading part.

[0006] The embodiment of the present invention adopts a thermal expansion pitch changing part to change the pitch, which can avoid the influence of the change of the ambient temperature on the size change of the conveying and transferring mechanism.

[0007] In some embodiments, the thermal expansion displacement portion is located on one side of the loading portion.

[0008] In some embodiments, the thermal expansion displacement portion is located on both sides of the loading portion.

[0009] In some embodiments, at least one second driving unit is further provided, the number of the second driving units being the same as the number of the loading units and being located at the top of the loading unit, and being capable of reciprocating the material within a range from the top of the loading unit to the bottom of the loading unit.

[0010] In some embodiments, there are multiple loading units, and each loading unit can operate independently.

[0011] In some embodiments, each of the loading portions is capable of alternately loading and unloading materials.

[0012] The present invention provides a transfer mechanism. It has the following advantages: (1) For multi-loading unit transportation, a single loading unit and a multi-loading unit can be selected for loading and unloading, thus shortening the transportation cycle; (2) A single loading unit and a multi-loading unit can be transported alternately to meet the transportation needs. The transportation volume is increased, and the distance can be changed; (3) The loading unit is deformed by heat, and the distance change caused by heat can be automatically adjusted.

[0020] In order to more clearly understand the above-mentioned purposes, features and advantages of the present disclosure, the embodiments of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0022] At least in order to realize the transportation by using a single loading part or a multi-loading part reciprocating transmission and transplanting transportation structure, and to adjust the unloading transportation position according to different transportation distances, its functionality is met, the transmission time and production cycle are effectively shortened, and the above-mentioned technical problem of the influence of ambient temperature changes on the size change of the transmission and transfer mechanism can be avoided. The first embodiment of the present application provides a transfer mechanism, characterized in that it includes: a base, which is installed and fixed on the ground; at least one loading part, which is located on the upper surface of the base and is used to load materials; at least one first driving part, which is the same in number as the loading part and is installed in a one-to-one manner on the lower part of the loading part, and can make the loading part reciprocate linearly on the upper surface of the base; and at least one thermal expansion variable distance part, which is installed below the loading part and can change the distance according to the temperature change of the loading part.

[0023] It can be understood that the transfer mechanism provided by the embodiment of the present application can effectively improve the technical defects of the transfer mechanism using related technologies.

[0024] Combine the following Figure 1-Figure 4 The above transfer mechanism is exemplified and the structure of the transfer mechanism is exemplified. It should be noted that those skilled in the art can design different transfer mechanisms based on the concept of the above transfer mechanism according to specific needs. Figure 1-Figure 4 institution.

[0025] First, briefly introduce the Figure 1-Figure 4 corresponding components or units.

[0026] Reference numeral 1 is used to characterize the base, which is also called the mobile base; reference numeral 2 is used to characterize the loading part, which is also called the bin; reference numeral 3 is used to characterize the first driving part, which is the X-axis driving transmission mechanism; reference numeral 4 is used to characterize the second driving part, which is the Y-axis driving transmission mechanism; reference numeral 5 is used to characterize the thermal expansion variable distance part, which is the heat-induced variable distance mechanism.

[0027] Secondly, the transfer mechanisms of some embodiments of the present application are exemplarily described in combination with the above-mentioned figure marks.

[0028] Figure 1 It is an overall schematic diagram of the transfer mechanism involved in the present invention, and the state of the transfer carrier (transfer material) is also shown in the figure. Figure 2The present invention relates to a transfer mechanism, wherein a single loading unit or multiple loading units are arranged in Figure 2 The conveying and transportation can be carried out with variable distance in the middle, left and right directions.

[0029] like Figure 1 As shown, the transfer mechanism provided by an embodiment of the present invention is characterized in that it includes: a base 1, which is installed and fixed on the ground; at least one loading part 2, which is located on the upper surface of the base 1 and is used to load materials; at least one first driving part 3, which is the same in number as the loading parts 2 and is installed at the lower part of the loading part 2, and can make the loading part 2 move back and forth linearly on the upper surface of the base 1; and at least one thermal expansion variable distance part 5, which is installed below the loading part 2 and can change distance according to the temperature change of the loading part 2.

[0030] Here, the base 1 is installed on a horizontal reference ground, and after adjusting the level, it is fixed to the ground by, for example, chemical bolts. The first driving part 3 can be an X-axis driving transmission mechanism (in Figure 1 In the figure, the left and right directions of the paper are the X-axis directions), the X-axis driving transmission mechanism is installed at the lower part of the single bin (loading part 2) bin body by bolts (e.g., in a one-to-one correspondence manner), and the X-axis driving transmission mechanism includes but is not limited to a driving motor, a gear rack, a linear module combination, etc. The material can be a carrier, or a silicon wafer, a substrate, etc.

[0031] like Figure 4 As shown, the thermal expansion and displacement unit 5 is located at one side of the loading unit 2. In the mechanism of the thermal expansion and displacement unit 5, one end of the conveying rack is fixed, and the other end is applicable to move left and right.

[0032] That is, under a single bin (loading part 2), there is a heat expansion variable distance part 5 as a heat variable distance device on one side of the bin, which can ensure that the transfer mechanism of the present invention will not be affected by the change of temperature on the size (especially the length size of the long span) under different temperature environments, and the equipment can adapt to such changes and easily produce large stress and deformation, so that the transfer mechanism of the present invention can always maintain normal operation.

[0033] However, those skilled in the art should understand that the thermal expansion displacement portion 5 may also be located on both sides of the loading portion 2 (not shown).

[0034] like Figure 1 As shown, the transfer mechanism also has at least one second driving unit 4, which has the same number as the loading unit 2 and is located at the top of the loading unit 2, and can move the material back and forth within the range from the top of the loading unit 2 to the bottom of the loading unit 2.

[0035] Of course, the second driving part 4 can also be installed in the middle of the loading part 2 .

[0036] like Figure 2 As shown, the second driving unit 4 can be a Y-axis driving transmission mechanism (in Figure 1 In the figure, the up and down direction of the paper is the Y-axis direction), the Y-axis driving transmission mechanism is installed on the upper part of the warehouse body by bolts, and the Y-axis driving transmission mechanism includes but is not limited to a driving motor, a gear rack, etc.

[0037] like Figure 1 As shown, there are multiple loading sections 2, that is, a multi-bin structure is adopted, and each loading section 2 can operate independently.

[0038] That is, the transplanting mechanism of the present invention can receive the carrier in a single bin (loading part 2) and carry out the Y-axis delivery and unloading, or can receive the carrier in multiple bins (loading part 2) at the same time and carry out the Y-axis delivery and unloading. In addition, it can also move in the X-axis direction with variable pitch and unload materials in multiple bins at the same time, and can also meet the selection of single bin and multi-bin unloading.

[0039] Although Figure 1 and Figure 2 The number of bins as the loading part 2 shown in the figure is four, but it is not limited thereto, and may be one bin (single bin) or three bins, five bins (multi-bin), etc. Furthermore, the loading part 2 may be fixed to the base 1 by bolts.

[0040] Each loading part 2 can alternately load and unload materials. In the process of alternately loading and unloading materials in the loading part 2, there is a carrier plate, which is transported from the previous station to the loading part for caching through the upper drive conveying mechanism. When the carrier plate needs to be transported, it is transported to the next station through the upper drive conveying mechanism.

[0041] The loading part 2 receives the carrier from any input port. The carrier can be loaded and unloaded forward and backward through, for example, a Y-axis driven conveying mechanism, or can be transported by the X-axis driven conveying mechanism with the bin (loading part 2) to move left and right for unloading. In addition, the X-axis moving direction can be adjusted and controlled by the X-axis driven conveying mechanism to control different transportation distances, transport the carrier to different positions, and unload freely.

[0042] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0043] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.
