Description

Technical Field

[0001] The utility model belongs to the technical field of slit coating machines, and in particular relates to a fully automatic loading and unloading coating machine. Background Art

[0002] The slit coater is the core equipment for the production of perovskite solar cells.

[0003] In the related art, announcement number: CN219003605U requires a positioning and transferring mechanism to load and transfer the glass substrate. In the mass production process, for large-sized glass substrates, after using the positioning and transferring mechanism to load the material, it is necessary to wait for the coating to be completed before loading the next glass substrate, resulting in low efficiency of the entire working process; and in this patent, when the coating module receives the glass substrate, it directly coats it. This direct coating method makes the coating material on the surface of the substrate less uniform and less stable during subsequent use. Therefore, pre-coating is required before coating. However, in the loading-pre-coating-coating process, the width of a general pre-coating mechanism is too large to be compatible with the loading mechanism, which can easily cause the glass substrate to get stuck during the transition from loading-pre-coating or pre-coating-coating.

[0004] Therefore, how to better adapt the three modules of loading-precoating-coating during the conveying process is a technical problem that needs to be solved urgently in this field. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a fully automatic loading and unloading coating machine, which includes: a coating mechanism; a feeding mechanism, which is located on one side of the coating mechanism and has a pre-coating gap between the feeding mechanism and the coating mechanism; and a pre-coating mechanism, which is arranged at the pre-coating gap; wherein the feeding mechanism is suitable for conveying a glass substrate to the coating mechanism, and the pre-coating mechanism is suitable for pre-coating the glass substrate located in the pre-coating gap; the feeding mechanism, the pre-coating mechanism, and the coating mechanism are arranged in sequence on the same horizontal plane; the width K of the pre-coating gap is less than one-third of the length L of the glass substrate.

[0007] Furthermore, the coating mechanism includes: a coating platform; and two synchronous belts, respectively located on both sides of the coating platform, suitable for receiving the glass substrate transported by the feeding mechanism; wherein the pre-coating gap is between the synchronous belt and the feeding mechanism.

[0008] Furthermore, the feeding mechanism includes: a plurality of conveying rollers; the distance between a conveying roller close to the synchronous belt and the synchronous belt is the pre-coating gap.

[0009] Furthermore, the conveying surface of the conveying roller, the coating surface of the pre-coating mechanism, and the conveying surface of the synchronous belt are in the same plane.

[0010] Furthermore, the coating mechanism also includes: a lifting mechanism arranged below the coating platform; a lifting pin group of the lifting mechanism passes through the coating platform from bottom to top, and the upper end surface of the lifting pin group is flush with the conveying surface of the synchronous belt to receive the glass substrate.

[0011] Furthermore, the lifting mechanism also includes: a mounting frame and a driving mechanism; wherein the lifting pin group is vertically arranged on the mounting frame; the synchronous belt is connected to the mounting frame through a profile rod; and the driving mechanism is suitable for driving the mounting frame to rise and fall to drive the synchronous belt and the lifting pin group to rise and fall.

[0012] Furthermore, a lifting hole group adapted to the lifting needle group is provided on the coating platform; the lifting needle group is suitable for passing through the coating platform through the lifting hole group.

[0013] Furthermore, a ventilation hole group is provided on the coating platform; the coating platform is suitable for air floating or adsorbing the glass substrate through the ventilation hole group.

[0014] Furthermore, a plurality of positioning components are arranged around the coating platform; when the coating platform air-floats the glass substrate, the positioning components are suitable for moving toward the glass substrate to clamp it.

[0016] The beneficial effect of the utility model is that the fully automatic loading and unloading coating machine leaves a pre-coating gap between the coating mechanism and the feeding mechanism and installs the pre-coating mechanism, and pre-coating is first performed on the pre-coating mechanism before formal coating on the glass substrate. After the pre-coating reaches an ideal state, the glass substrate is coated, and the feeding mechanism, the pre-coating mechanism, and the coating mechanism are sequentially arranged on the same horizontal plane, so that in the mass production process of perovskite battery cells, one by one is continuously transported, the coating speed is fast, the coating uniformity is good, and the stability is high.

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] like Figure 1 , Figure 2 As shown, at least one embodiment provides a fully automatic loading and unloading coating machine, which includes: a coating mechanism 1; a feeding mechanism 2, which is located on one side of the coating mechanism 1 and has a pre-coating gap 21 between the feeding mechanism 2 and the coating mechanism 1; and a pre-coating mechanism 3, which is arranged at the pre-coating gap 21; wherein the feeding mechanism 2 is suitable for conveying a glass substrate 4 to the coating mechanism 1, and the pre-coating mechanism 3 is suitable for pre-coating the glass substrate 4 located in the pre-coating gap 21; the feeding mechanism 2, the pre-coating mechanism 3, and the coating mechanism 1 are arranged in sequence on the same horizontal plane; the width K of the pre-coating gap 21 is less than one-third of the length L of the glass substrate 4.

[0034] In some embodiments, a loading mechanism 2 is used instead of a positioning and transferring mechanism. When loading, the positioning and transferring mechanism only grabs the edge position of the glass substrate 4, leaving the middle of the glass substrate 4 vacant, causing deformation when subjected to force. Moreover, after loading using the positioning and transferring mechanism, it is necessary to wait until the coating is completed before loading the next glass substrate 4, resulting in low efficiency of the entire working process. Specifically, the loading mechanism 2 includes a plurality of conveying rollers 22, which can effectively support the edge position and the middle position of the glass substrate 4, preventing the glass substrate 4 from being deformed when subjected to force during pre-coating, and improving the overall mass production efficiency.

[0035] In some embodiments, in order to pre-coat the glass substrate 4 before formal coating, a pre-coating gap 21 is required between the coating mechanism 1 and the feeding mechanism 2 to set up the pre-coating mechanism 3. The width of the pre-coating mechanism 3 is as small as possible to ensure that the glass substrate 4 can smoothly transition from the feeding mechanism 2 to the coating mechanism 1 to avoid jamming. Specifically, the width K of the pre-coating gap 21 is less than one-third of the length L of the glass substrate 4.

[0036] like Figure 3As shown, in some embodiments, a loading mechanism 2 is provided on one side of the coating mechanism 1, and a unloading mechanism is provided on the other side; the coating mechanism 1 comprises: a coating platform 11; and two synchronous belts 12, respectively located on both sides of the coating platform 11, suitable for receiving the glass substrate 4 conveyed by the loading mechanism 2; wherein the pre-coating gap 21 is formed between the synchronous belt 12 and the loading mechanism 2; wherein the conveying speed of the synchronous belt 12 is consistent with the conveying speed of the loading mechanism 2 and the conveying speed of the unloading mechanism, so as to ensure that the glass substrate 4 can smoothly transition from the loading mechanism 2 to the coating platform 11 and from the coating platform 11 to the unloading mechanism.

[0037] In some embodiments, the feeding mechanism 2 includes: a conveying roller 22 close to the synchronous belt 12, the distance between the synchronous belt 12 is the pre-coating gap 21; at the same time, the conveying surface of the conveying roller 22, the coating surface of the pre-coating mechanism 3, and the conveying surface of the synchronous belt 12 are in the same plane.

[0038] like Figure 4 As shown, in some embodiments, the coating mechanism 1 further includes: a lifting mechanism 13 disposed below the coating platform 11; a lifting pin group 131 of the lifting mechanism 13 passes through the coating platform 11 from bottom to top, and the upper end surface of the lifting pin group 131 is flush with the conveying surface of the synchronous belt 12 to receive the glass substrate 5; specifically, the lifting mechanism 13 further includes: a mounting frame 132 and a driving mechanism 133; wherein the lifting pin group 131 is vertically arranged on the mounting frame 132; the synchronous belt 12 is connected to the mounting frame 132 through a profile rod; the driving mechanism 133 is suitable for driving the mounting frame 132 to rise and fall to drive the synchronous belt 12 and the lifting pin group 131 to rise and fall.

[0039] like Figure 5 As shown, in some embodiments, a lifting hole group 111 adapted to the lifting needle group 131 is opened on the coating platform 11; the lifting needle group 131 is suitable for passing through the coating platform 11 through the lifting hole group 111.

[0040] In some embodiments, a vent hole group 112 is provided on the coating platform 11; the coating platform 11 is suitable for floating or adsorbing the glass substrate 4 through the vent hole group 112; specifically, when it is necessary to receive the glass substrate 4, the driving mechanism 133 drives the lifting pin group 131 to extend out of the lifting hole group 111, and after receiving the glass substrate 5, the driving mechanism 133 drives the lifting pin group 131 to gradually descend so that the glass substrate 4 is placed on the coating platform 11.

[0041] In some embodiments, a plurality of positioning components 14 are disposed around the coating platform 11 ; when the coating platform 11 floats the glass substrate 4 , the positioning components 14 are adapted to move toward the glass substrate 4 to clamp it.

[0042] like Figure 6 As shown, in some embodiments, the positioning assembly 14 includes: a pneumatic slide 141, a lifting cylinder 142, a clamping positioning wheel 143 and a protective cover 144; wherein the pneumatic slide 141 is connected to the coating platform 11, the lifting cylinder 142 is slidably arranged on the pneumatic slide 141, the clamping positioning wheel 143 is arranged on the lifting cylinder 142, and the protective cover 144 is connected to the coating platform 11 to cover the pneumatic slide 141 and the lifting cylinder 142; specifically, when the ejector needle group 131 After the glass substrate 4 is placed on the coating platform 11 driven by the synchronous belt 12, the coating platform 11 starts the air flotation function, that is, it sprays air outwards through the vent group 112 to suspend the glass substrate 4, and then the clamping positioning wheels 143 in each positioning component 14 move along the pneumatic slide 141 until the glass substrate 4 is clamped. At this time, the glass substrate 4 is positioned, and then the coating platform 11 stops spraying and starts the adsorption function, that is, it sucks air inwards through the vent group 112 so that the glass substrate 4 is adsorbed on the coating platform 11 by negative pressure.

[0043] In summary, the fully automatic loading and unloading coating machine leaves a pre-coating gap 21 between the coating mechanism 1 and the loading mechanism 2 and installs the pre-coating mechanism 3, so that the glass substrate 4 is pre-coated before the formal coating, thereby improving the coating effect of the glass substrate 4.

[0044] The synchronous belt 2 and the lifting mechanism 3 are used to jointly receive the glass substrate 5. The two synchronous belts 2 are respectively used to support the two side edges of the glass substrate 5, and the lifting needle group 31 is used to support the middle of the glass substrate 5, so that the contact surface with the glass substrate 5 can be reduced as much as possible; at the same time, in the process of conveying the glass substrate 5, the synchronous belt 2 can absorb the glass substrate 5 through the negative pressure hole group 21 thereon to prevent the glass substrate 5 from deviating during the conveying process.
