Description

Technical Field

[0001] This utility model belongs to the field of perovskite laser scribing technology, and particularly relates to a transfer platform, a transfer device for laser scribing, and a laser scribing system. Background Technology

[0002] In the production process of perovskite solar cells, it is necessary to laser scribing the glass substrate and transfer the glass to a transfer platform. However, during the initial laser power debugging, it is unavoidable that if the laser power is too high, the laser will cut through the glass during scribing, causing the laser to hit the transfer platform and resulting in an uneven surface on the transfer platform.

[0003] Therefore, there is an urgent need to develop a new transfer platform, a transfer device for laser scribing, and a laser scribing system to solve the technical problem that laser penetration through glass will damage the surface flatness of the transfer platform.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0005] This disclosure provides at least one transfer platform, a transfer device for laser scribing, and a laser scribing system.

[0006] In a first aspect, embodiments of this disclosure provide a transfer platform, which includes: a platform body; wherein the platform body has a plurality of grooves; when the platform body supports a workpiece, the projection of each position to be marked on the workpiece onto the platform body is covered by the corresponding groove.

[0007] In one optional embodiment, the grooves are arranged equidistantly on the platform body, and the positions to be marked are arranged equidistantly on the workpiece; the arrangement distance between two adjacent grooves is equal to the arrangement distance between two adjacent positions to be marked.

[0008] In one optional embodiment, the groove width is 1mm-2.5mm, and the line width at the position to be marked is 0.01mm-0.08mm.

[0009] In one optional embodiment, the platform body is further provided with a plurality of adsorption grooves, and each adsorption groove is located between two corresponding grooves.

[0010] In one alternative implementation, Where μ is the friction coefficient of the platform body, m is the mass of the workpiece, g is the gravitational acceleration, P is the pressure of the workpiece on the platform body, a is the acceleration of the workpiece toward the platform body, k is the safety factor; S is the total area of ​​each of the adsorption tanks, so that each of the adsorption tanks can hold the workpiece on the platform body.

[0011] Secondly, embodiments of this disclosure also provide a transfer device for laser scribing, comprising: a transfer platform as described above, a first limiting mechanism, and a second limiting mechanism; wherein the first limiting mechanism is located on both sides of the platform body in the transfer platform, and the second limiting mechanism is located on the other two sides of the platform body in the transfer platform; the first limiting mechanism is adapted to push the workpiece to move on the platform body, the second limiting mechanism is adapted to push the workpiece to move on the platform body, and the pushing direction of the first limiting mechanism is perpendicular to the pushing direction of the second limiting mechanism, so that the projection of each scribing position on the workpiece on the platform body is covered by the corresponding groove.

[0012] In one optional embodiment, the first limiting mechanism includes: a plurality of first positioning blocks and a plurality of first pushing members; each of the first positioning blocks is located at one short side of the platform body, and each of the first pushing members is located at the other short side of the platform body; each of the first pushing members is adapted to synchronously push the workpiece on the platform body toward each of the first positioning blocks.

[0013] In one optional embodiment, the first limiting mechanism further includes: a plurality of first flexible layers; each of the first flexible layers is connected to a corresponding first pushing member, so that the first pushing member contacts the workpiece through the first flexible layer.

[0014] In one optional embodiment, the second limiting mechanism includes: a plurality of second positioning blocks, a plurality of second pushing members, and a plurality of second flexible layers; each of the second positioning blocks is located at one long side of the platform body, and each of the second pushing members is located at the other long side of the platform body; each of the second flexible layers is connected to the corresponding second pushing member so that the second pushing member contacts the workpiece through the second flexible layer; each of the second pushing members is adapted to synchronously push the workpiece on the platform body toward each of the second positioning blocks.

[0015] Thirdly, embodiments of this disclosure also provide a laser scribing system, which includes: a laser scribing transfer device as described above, for supporting a workpiece.

[0016] The beneficial effect of this utility model is that by opening grooves on the platform body and the position of the grooves corresponding to the positions to be scribed, the projection of each position to be scribed on the workpiece onto the platform body can be covered by the corresponding grooves. Even if the laser power is too high and penetrates the glass, the laser cannot hit the surface of the platform body because there is a buffer space between the glass and the platform body. Instead, it falls into the groove, avoiding damage to the platform body and thus ensuring the flatness of the platform body.

[0035] Research has revealed that the transfer platform in the existing technology is a common adsorption platform. When the laser scribing is performed, the laser will penetrate the glass and hit the transfer platform, causing the surface of the transfer platform to become uneven. Consequently, the transfer platform will no longer adhere to the glass, affecting the adsorption effect.

[0036] Based on the above research, this disclosure provides a transfer platform, a transfer device for laser scribing, and a laser scribing system. By slotting the transfer platform to provide a buffer space, the surface of the transfer platform can be prevented from being damaged by the laser after penetrating the glass, thus ensuring the flatness of the transfer platform surface.

[0037] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0039] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] like Figures 1 to 3 As shown, at least one embodiment provides a transfer platform, which includes: a platform body 1; wherein the platform body 1 is provided with a plurality of grooves 11; when the platform body 1 supports the workpiece 2, the projection of each position 21 to be marked on the workpiece 2 onto the platform body 1 is covered by the corresponding groove 11.

[0041] Specifically, workpiece 2 can be glass.

[0042] In at least one embodiment, by creating a groove 11 on the platform body 1, and the position of the groove 11 corresponds to the position 21 to be scribed, that is, the projection of each position 21 to be scribed on the workpiece 2 onto the platform body 1 can be covered by the corresponding groove 11. Even if the laser power is too high and causes it to penetrate the glass, since there is a buffer space between the glass and the platform body 1, the laser cannot hit the surface of the platform body 1, but falls into the groove 11, thus avoiding damage to the platform body 1 and ensuring the flatness of the platform body 1.

[0043] In at least one embodiment, please refer to Figure 2 Each groove 11 is arranged at equal intervals on the platform body 1, and each marking position 21 is arranged at equal intervals on the workpiece 2; the arrangement distance between two adjacent grooves 11 is equal to the arrangement distance between two adjacent marking positions 21.

[0044] Specifically, please refer to Figure 2 The distance between the center line of any groove 11 and the center line of the adjacent groove 11 is L1, that is, the layout distance between two adjacent grooves 11 is L1, and the distance between the center line of any position 21 to be marked and the center line of the adjacent position 21 to be marked is L1, that is, the layout distance between two adjacent positions 21 to be marked is L1.

[0045] In at least one embodiment, please refer to Figure 2 The groove 11 has a groove width of 1mm-2.5mm, and the line width of the position to be marked 21 is 0.01mm-0.08mm.

[0046] Specifically, please refer to Figure 2 The groove width of groove 11 is denoted as L2, and the distance of L2 is 1mm-2.5mm, and L2 can be 1mm, 1.5mm, 2mm, or 2.5mm.

[0047] Specifically, please refer to Figure 2 The line width of position 21 to be drawn is denoted as L3, and the distance of L3 is 0.01mm-0.08mm, and L2 can be 0.01mm, 0.03mm, 0.05mm, or 0.08mm.

[0048] In at least one embodiment, please refer to Figure 3 The platform body 1 is also provided with a number of adsorption grooves 12, and each adsorption groove 12 is located between two corresponding grooves 11.

[0049] Specifically, a connector 5 is provided to communicate with each adsorption tank 12, and the connector 5 is connected to the adsorption equipment, so that the workpiece 2 can be adsorbed onto the platform body 1 through each adsorption tank 12.

[0050] In at least one embodiment, Wherein, μ is the friction coefficient of the platform body 1, m is the mass of the workpiece 2, g is the gravitational acceleration, P is the pressure of the workpiece 2 on the platform body 1, a is the acceleration of the workpiece 2 toward the platform body 1, k is the safety factor; S is the total area of ​​each of the adsorption grooves 12, so that each of the adsorption grooves 12 can hold the workpiece 2 on the platform body 1.

[0051] Specifically, since the platform body 1 has grooves 11, in order to be able to hold the workpiece 2 on the platform body 1, the total area of ​​each adsorption groove 12 needs to meet the requirements of the above formula.

[0052] Specifically, if the mass of workpiece 2 is 1 kg, the pressure is -70 kPa, the coefficient of friction is 0.3, the safety factor is 3, and the acceleration is 1 m / s², then the total area of ​​each adsorption tank 12 needs to be no less than 2.86 × 10⁻⁶ m². -6 m 2 .

[0053] Based on the same technical concept, please refer to Figures 1 to 3 At least one embodiment also provides a transfer device for laser marking, comprising: a transfer platform as described above, a first limiting mechanism 3, and a second limiting mechanism 4; wherein the first limiting mechanism 3 is located on both sides of the platform body 1 in the transfer platform, and the second limiting mechanism 4 is located on the other two sides of the platform body 1 in the transfer platform; the first limiting mechanism 3 is adapted to push the workpiece 2 to move on the platform body 1, the second limiting mechanism 4 is adapted to push the workpiece 2 to move on the platform body 1, and the pushing direction of the first limiting mechanism 3 is perpendicular to the pushing direction of the second limiting mechanism 4, so that the projection of each marking position 21 on the workpiece 2 on the platform body 1 is covered by the corresponding groove 11.

[0054] Specifically, the transfer platform is installed on the base plate 15.

[0055] Specifically, please refer to Figure 1 The first limiting mechanism 3 pushes the workpiece 2 to move on the platform body 1 along the F1 direction.

[0056] Specifically, please refer to Figure 1 The second limiting mechanism 4 pushes the workpiece 2 to move on the platform body 1 along the F2 direction.

[0057] In at least one embodiment, the first limiting mechanism 3 includes: a plurality of first positioning blocks 31 and a plurality of first pushing members 32; each of the first positioning blocks 31 is located at one short side 13 of the platform body 1, and each of the first pushing members 32 is located at the other short side 13 of the platform body 1; each of the first pushing members 32 is adapted to synchronously push the workpiece 2 on the platform body 1 toward each of the first positioning blocks 31.

[0058] Specifically, each of the first positioning blocks 31 is located on the same straight line, and the function of the first positioning block 31 is to limit the workpiece 2 as a reference surface.

[0059] Specifically, the first pusher 32 is mounted on the first mounting bracket 34.

[0060] In at least one embodiment, the first limiting mechanism 3 further includes: a plurality of first flexible layers 33; each of the first flexible layers 33 is connected to a corresponding first pushing member 32 so that the first pushing member 32 contacts the workpiece 2 through the first flexible layer 33.

[0061] In at least one embodiment, the second limiting mechanism 4 includes: a plurality of second positioning blocks 41, a plurality of second pushing members 42, and a plurality of second flexible layers 43; each of the second positioning blocks 41 is located at one long side 14 of the platform body 1, and each of the second pushing members 42 is located at the other long side 14 of the platform body 1; each of the second flexible layers 43 is connected to the corresponding second pushing member 42 so that the second pushing member 42 contacts the workpiece 2 through the second flexible layer 43; each of the second pushing members 42 is adapted to synchronously push the workpiece 2 on the platform body 1 toward each of the second positioning blocks 41.

[0062] Specifically, the second pusher 42 is mounted on the second mounting bracket 44.

[0063] Based on the same technical concept, please refer to Figures 1 to 3 At least one embodiment also provides a laser scribing system, which includes: a laser scribing transfer device as described above, for supporting the workpiece 2.

[0064] In summary, this utility model creates grooves on the platform body, with the grooves corresponding to the positions to be scribed. This means that the projections of each scribing position on the workpiece onto the platform body can be covered by the corresponding grooves. Even if the laser penetrates the glass, due to the buffer space between the glass and the platform body, the laser cannot hit the surface of the platform body but falls into the groove, thus avoiding damage to the platform body and ensuring the flatness of the platform body.

[0065] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0066] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0067] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0068] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
