Description

TECHNICAL FIELD

[0001] The present application relates to the field of photovoltaic production equipment, in particular to a wafer body regularizing device. BACKGROUND

[0002] During the conveying process of the battery wafer and the like, the position of the wafer body often needs to be regularized. The traditional regularizing method is to arrange regularizing assemblies on both sides of the conveying line of the wafer body. The regularizing assembly may include a regularizing wheel set and a driving mechanism, for example. The regularizing wheel set is fixedly installed on the driving end of the driving mechanism. The driving mechanisms on both sides of the regularizing assembly drive the corresponding regularizing wheel sets to approach the wafer body at the same time, so as to push the two side edges of the wafer body and regularize the wafer body.

[0003] In the traditional regularizing assembly, the minimum distance between the regularizing wheel sets on both sides is greater than the width of the wafer body when the regularizing wheel sets on both sides approach the clamped wafer body, so as to avoid crushing the wafer body. However, this method has the problem that the regularizing effect of the wafer body is poor and cannot guarantee that all the regularized wafer bodies are oriented in the same direction. CONTENT OF THE UTILITY MODEL

[0004] In view of the above technical problems, the present application provides a wafer body regularizing device, and the detailed technical scheme is as follows:

[0005] A wafer body regularizing device includes a conveying mechanism, a reference mechanism, and a regularizing driving mechanism, wherein:

[0006] The conveying mechanism is configured to convey the wafer body in a first direction. At least one regularizing station is arranged on the conveying path of the conveying mechanism.

[0007] The reference mechanism is arranged on the first side of the regularizing station. The reference mechanism has a regularizing reference surface facing the regularizing station. The regularizing reference surface extends in the first direction.

[0008] The regularizing driving mechanism is configured to push the wafer body located in the regularizing station towards the reference mechanism, so that one side edge of the wafer body is tightly attached to the regularizing reference surface.

[0009] The wafer body regularizing device provided by the present application pushes the wafer body in the regularizing station from one side towards the reference mechanism by the regularizing driving mechanism, so that one side edge of the wafer body is tightly attached to the regularizing reference surface, thereby completing the regularizing of the wafer body. The regularizing reference surface of the present application is uniform, which can guarantee that all the regularized wafer bodies are oriented in the same direction and have a good regularizing effect.

[0010] In some embodiments, the regularizing driving mechanism includes a first mounting bracket and at least one first adsorption block arranged on the first mounting bracket. The first adsorption block is located above the wafer body in the regularizing station.

[0011] The first suction block is configured to blow high-speed airflow at least towards the reference mechanism to generate a suction area for the sheet below the first suction block and to push the sheet towards the reference mechanism.

[0012] The first suction block above the sheet at the shaping station blows high-speed airflow towards the reference mechanism, and the effect generated thereby is that a suction area is generated below the first suction block under the action of the Bernoulli effect, so that the first suction block non-contactingly suctions the sheet. At the same time, since the first suction block blows air towards the reference mechanism, the suctioned sheet is pushed towards the reference mechanism, so that one side edge of the sheet is tightly attached to the shaping reference surface, and shaping is achieved.

[0013] During shaping, the first suction block is always non-contacting with the sheet, so that pressure damage to the sheet is avoided. The first suction block can suction the sheet to make the sheet completely or partially separate from the conveying mechanism, so that the friction between the sheet and the conveying mechanism is reduced when the sheet moves towards the reference mechanism.

[0014] In some embodiments, the first suction block is further configured to blow high-speed airflow away from the reference mechanism, wherein the amount of the high-speed airflow blown by the first suction block towards the reference mechanism is greater than the amount of the high-speed airflow blown by the first suction block away from the reference mechanism.

[0015] The two-side simultaneous air blowing manner can form a suction area below the first suction block, which is more stable and uniform in suction force, so as to ensure that the sheet remains in a horizontal state after being suctioned and improve the shaping effect. In addition, since the amount of the high-speed airflow blown by the first suction block towards the reference mechanism is greater than the amount of the high-speed airflow blown by the first suction block away from the reference mechanism, the blowing force of the first suction block towards the reference mechanism is greater than the blowing force of the first suction block away from the reference mechanism, so that the suctioned sheet is pushed towards the reference mechanism.

[0016] In some embodiments, the shaping driving mechanism comprises two first suction blocks arranged side by side along a second direction on the first mounting bracket, wherein the second direction is perpendicular to the first direction.

[0017] The two first suction blocks cooperate to implement suction of the sheet, which can further improve the suction stability of the sheet and prevent the sheet from tilting.

[0018] In some embodiments, the first suction block comprises a base and a core, wherein: the bottom of the base is provided with a mounting gap extending along the first direction, the core is embedded in the mounting gap, the core is provided with a first air cavity in communication with the compressed gas source, and a first air blowing gap is formed between the first side edge of the core and the base and is in communication with the first air cavity; the high-pressure gas supplied by the compressed gas source enters the first air cavity and is blown at high speed towards the reference mechanism through the first air blowing gap.

[0019] The first adsorption block is arranged to enable the first adsorption block to blow high-speed airflow towards the reference mechanism to generate an adsorption area for adsorbing the sheet below the first adsorption block and to drive the sheet to push towards the reference mechanism. The first adsorption block is arranged as a split assembly mechanism composed of the base and the core, which facilitates the processing and molding of the internal air path structure of the first air cavity, the first air blowing gap, etc., and facilitates the maintenance of the first adsorption block.

[0020] In some embodiments, the core is further provided with a second air cavity in communication with the compressed gas source, and a second air blowing gap is formed between the second side edge of the core and the base and in communication with the second air cavity; the high-pressure gas supplied by the compressed gas source enters the second air cavity and is blown away from the reference mechanism at high speed through the second air blowing gap; the flow rate of the airflow blown by the first air blowing gap is greater than the flow rate of the airflow blown by the second air blowing gap.

[0021] The first adsorption block blows air towards both sides at the same time, thereby forming an adsorption area below the first adsorption block with more stable and uniform adsorption force, ensuring that the sheet remains in a horizontal state after being adsorbed, and improving the regularity effect. In addition, since the flow rate of the airflow blown by the first air blowing gap is greater than the flow rate of the airflow blown by the second air blowing gap, the blowing force of the first adsorption block towards the reference mechanism is greater than the blowing force away from the reference mechanism, thereby ensuring that the adsorbed sheet is pushed towards the reference mechanism.

[0022] In some embodiments, the regularity driving mechanism includes a second mounting bracket, an air blowing block arranged on the second mounting bracket, and at least one second adsorption block, wherein the second adsorption block is located above the sheet at the regularity station, the air blowing block is located at the second side of the regularity station opposite to the first side, or the air blowing block is located above the sheet at the regularity station; the second adsorption block is configured to blow high-speed airflow at least to one side of the second adsorption block to generate an adsorption area for adsorbing the sheet below the second adsorption block; and the air blowing block is configured to blow air towards the adsorbed sheet to push the adsorbed sheet towards the reference mechanism.

[0023] The second adsorption block located above the sheet at the regularity station blows high-speed airflow at least to one side, thereby generating an adsorption area below the second adsorption block, so that the second adsorption block adsorbs the sheet in a non-contact manner. At the same time, the air blowing block blows air towards the adsorbed sheet, so that the adsorbed sheet is pushed towards the reference mechanism, so that one side edge of the sheet is tightly attached to the regularity reference surface, and regularity is achieved. During the regularity process, neither the second adsorption block nor the air blowing block contacts the sheet, avoiding pressure damage to the sheet.

[0024] In some embodiments, the regularity driving mechanism includes two second adsorption blocks arranged side by side on the second mounting bracket in a second direction; wherein the second direction is perpendicular to the first direction.

[0025] Two second adsorption blocks are matched to implement adsorption on the sheet, which can further improve the adsorption stability of the sheet and prevent the sheet from tilting.

[0026] In some embodiments, the conveying mechanism includes a first conveying section and a second conveying section arranged at intervals along the first direction, and a regular station is formed between the output end of the first conveying section and the input end of the second conveying section; the regular driving mechanism includes a third adsorption block located below the sheet at the regular station, and the third adsorption block is configured to blow high-speed airflow at least towards the reference mechanism to generate an adsorption area above the third adsorption block for adsorbing the sheet and push the sheet towards the reference mechanism.

[0027] The third adsorption block located below the sheet at the regular station blows high-speed airflow towards the reference mechanism, and the effect generated thereby is that an adsorption area is generated above the third adsorption block under the action of the Bernoulli effect, so that the third adsorption block adsorbs and supports the sheet passing from above in a non-contact manner. At the same time, since the third adsorption block blows air towards the reference mechanism, the adsorbed sheet is pushed towards the reference mechanism, so that one side edge of the sheet is tightly attached to the regular reference surface, and regularity is achieved.

[0028] In addition, the third adsorption block is arranged in the gap between the first conveying section and the second conveying section, which saves installation space and makes the structure of the sheet regularity device of the present application simpler.

[0029] In some embodiments, the reference mechanism includes a belt arranged along the first direction, and the outer side of the belt body near the regular station constitutes the regular reference surface; or the reference mechanism includes a plurality of rollers arranged at intervals along the first direction, and the outer circumferential surface of the plurality of rollers towards the regular station constitutes the regular reference surface.

[0030] Using a belt as the reference mechanism makes the pushed sheet have flexible contact with the belt, which further reduces the risk of damage to the sheet while ensuring the regularity effect. Using a plurality of rollers arranged at intervals along the first direction as the reference mechanism, when the sheet contacts the rollers, the rotating rollers can reduce the friction force on the sheet and prevent the sheet from being abraded.

[0042] The sheet body 100. DETAILED DESCRIPTION

[0043] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0044] As described in the background section, in the conventional sizing assembly, the minimum distance between the two sizing wheel sets on the two sides is greater than the width of the sheet body when the two sizing wheel sets are close to the clamped sheet body, so as to avoid crushing the sheet body, and thus the problems are that the sizing effect of the sheet body is poor and the orientations of all the sized sheet bodies cannot be guaranteed to be consistent.

[0045] In view of this, the present application provides a sheet body sizing device which can guarantee that the orientations of all the sized sheet bodies are consistent. As shown in Figure 1 The sheet body sizing device of the present application comprises a conveying mechanism 1, a reference mechanism 2, and a sizing driving mechanism 3, wherein:

[0046] The conveying mechanism 1 is configured to convey the sheet body 100 in a first direction (e.g., the X direction), and at least one sizing station is arranged on the conveying path of the conveying mechanism 1.

[0047] The reference mechanism 2 is arranged on the first side (e.g., the A side in Figure 1 ) of the sizing station, and the reference mechanism 2 has a sizing reference surface 21 facing the sizing station, wherein the sizing reference surface 21 extends in the first direction.

[0048] The regularizing driving mechanism 3 is configured to push the sheet body 100 at the regularizing station towards the reference mechanism 2, so that one side of the sheet body 100 is tightly attached to the regularizing reference surface 21.

[0049] The sheet body regularizing device provided in the present application pushes the sheet body 100 at the regularizing station from one side towards the reference mechanism 2 by the regularizing driving mechanism 3, so that one side of the sheet body 100 is tightly attached to the regularizing reference surface 21, thereby completing the regularizing of the sheet body 100. Since the regularizing reference surface 21 is uniform, it can ensure that all the regularized sheet bodies 100 are consistent in the direction, and the regularizing effect is better.

[0050] In addition, the reference mechanism 2 of the present application is only arranged on the first side of the conveying mechanism 1, and the second side of the conveying mechanism 1 is not provided with the reference mechanism 2, which makes more size range of sheet bodies 100 can enter the regularizing station, and the application range is wider.

[0051] The sheet body regularizing device provided in the present application can be applied to the regularizing of rectangular sheet bodies such as battery sheets.

[0052] Figures 1 to 2 In the embodiment shown, the regularizing driving mechanism 3 includes a first mounting bracket 31 and at least one first adsorption block 32 arranged on the first mounting bracket 31, and the first adsorption block 32 is located above the sheet body 100 at the regularizing station. As shown in Figure 2 As shown, the first adsorption block 32 is configured to at least blow high-speed airflow a towards the reference mechanism 2, so as to generate an adsorption area below the first adsorption block 32 for adsorbing the sheet body 100, and drive the sheet body 100 to be pushed towards the reference mechanism 2.

[0053] When the sheet body 100 is conveyed to the regularizing station, the first adsorption block 32 at least blows high-speed airflow a towards the reference mechanism 2, and the effect generated thereby is that: under the action of Bernoulli effect, an adsorption area is generated below the first adsorption block 32, so that the first adsorption block 32 adsorbs the sheet body 100 in a non-contact manner. At the same time, since the first adsorption block 32 blows air towards the reference mechanism 2, the adsorbed sheet body 100 is pushed towards the reference mechanism 2, so that one side of the sheet body 100 is tightly attached to the regularizing reference surface 21, and the regularizing is realized.

[0054] In addition, during the regularizing process, the first adsorption block 32 is always not in contact with the sheet body 100, so it will not cause pressure damage to the sheet body 100. And the first adsorption block 32 can adsorb the sheet body, so that the sheet body is completely separated from the conveying mechanism 1, or partially separated from the conveying mechanism 1, so that when the sheet body 100 moves towards the reference mechanism 2, the friction between the sheet body 100 and the conveying mechanism 1 is reduced.

[0055] As shown in Figure 2As shown, optionally, the first suction block 32 is further configured to blow out a high-speed airflow b away from the reference mechanism 2, wherein the amount of the high-speed airflow a blown out by the first suction block 32 towards the reference mechanism 2 is greater than the amount of the high-speed airflow b blown out by the first suction block 32 away from the reference mechanism 2.

[0056] In this way, the first suction block 32 blows out a greater force towards the reference mechanism 2 than away from the reference mechanism 2, thereby ensuring that the sheet 100 is pushed towards the reference mechanism 2 after being sucked.

[0057] As shown, optionally, the regularizing driving mechanism 3 comprises two first suction blocks 32 arranged side by side along a second direction (e.g. the Y direction) on the first mounting bracket 31, wherein the second direction is perpendicular to the first direction. Figure 2

[0058] Of course, the regularizing driving mechanism 3 can also comprise only one first suction block 32, or three or more first suction blocks 32 arranged side by side along the second direction (e.g. the Y direction) on the first mounting bracket 31.

[0059] As shown, optionally, the first suction block 32 comprises a base 321 and a core, wherein the bottom of the base 321 is provided with a mounting groove 326 extending along the first direction, the core is embedded in the mounting groove 326, the core is provided with a first air cavity in communication with the compressed gas source, and a first air blowing gap in communication with the first air cavity is formed between the first side edge of the core and the base. Figures 3 to 4

[0060] In this way, the high-pressure gas supplied by the compressed gas source enters the first air cavity and is blown out at high speed towards the reference mechanism 2 through the first air blowing gap.

[0061] Optionally, the core comprises a gasket 322 and a core plate 323, wherein the gasket 322 is padded between the base 321 and the core plate 323, the first side edge of the gasket 322 is provided with a plurality of first notches 324, and the base 321 and the core plate 323 block the plurality of first notches 324 from the top and bottom sides to form a plurality of first air cavities. Figure 3 ​​In the embodiment shown, the first side edge of the gasket 322 is provided with four first notches 324, and correspondingly, four first air chambers are formed in the core.

[0062] Optionally, the core also has a second air chamber connected to a compressed air source, and a second air-blowing slit connected to the second air chamber is formed between the second side edge of the core and the base 321. High-pressure gas supplied by the compressed air source enters the second air chamber and is blown out at high speed away from the reference mechanism 2 through the second air-blowing slit. The flow rate of the airflow blown out from the first air-blowing slit is greater than that of the airflow blown out from the second air-blowing slit. That is, the first adsorption block 32 blows air to both sides simultaneously through the first and second air-blowing slits, thereby forming an adsorption area with more stable and uniform adsorption force below the first adsorption block 32, ensuring that the sheet 100 remains horizontal after being adsorbed, and improving the regularization effect. In addition, since the flow rate of the airflow blown out from the first air-blowing slit is greater than that of the airflow blown out from the second air-blowing slit, it is possible to ensure that the blowing force of the first adsorption block 32 toward the reference mechanism 2 is greater than the blowing force away from the reference mechanism 2, thereby ensuring that the adsorbed sheet 100 is pushed toward the reference mechanism 2.

[0063] like Figure 5 As shown, optionally, the second side edge of the gasket 322 is provided with a plurality of second notches 325, and the base 321 and the core plate 323 block the plurality of second notches 325 from the upper and lower sides to form a plurality of second air chambers. Figure 5 In the embodiment shown, four second notches 325 are also provided on the second side edge of the gasket 322, and correspondingly, four second air chambers are formed in the core.

[0064] In another alternative embodiment, the alignment drive mechanism includes a second mounting bracket and an air-blowing block and at least one second adsorption block disposed on the second mounting bracket. The second adsorption block is located above the sheet at the alignment station, and the air-blowing block is located on a second side of the alignment station opposite to the first side, or the air-blowing block is located above the sheet at the alignment station. The second adsorption block is configured to blow a high-speed airflow at least to one side of the second adsorption block to create an adsorption zone below the second adsorption block for adsorbing the sheet. The air-blowing block is configured to blow air toward the adsorbed sheet to push the adsorbed sheet toward the reference mechanism.

[0065] When the sheet 100 is conveyed to the straightening station, the second adsorption block above the sheet 100 at the straightening station blows a high-speed airflow to at least one side, thereby creating an adsorption zone below the second adsorption block, allowing the second adsorption block to adsorb the sheet 100 in a non-contact manner. At the same time, the blowing block blows air toward the adsorbed sheet, thereby pushing the adsorbed sheet toward the reference mechanism 2, so that one side of the sheet 100 is pressed against the straightening reference surface 21, achieving straightening.

[0066] Similarly, during the alignment process, neither the second adsorption block nor the air blowing block comes into contact with the tablet, thus avoiding pressure damage to the tablet. In addition, by setting a dedicated air blowing block to blow air toward the adsorbed tablet, it is ensured that a sufficiently large pushing force is applied to the tablet to push it toward the reference mechanism.

[0067] The second adsorption block can adopt the same structure as the first adsorption block 32 in the previous embodiment. In particular, since the second adsorption block does not need to push the sheet, when the second adsorption block is configured to blow air to both sides simultaneously, the flow rate of the airflow blown to both sides can be set to be equal, thus forming an adsorption zone with more uniform adsorption force below the second adsorption block.

[0068] Similarly, optionally, the alignment drive mechanism includes two second adsorption blocks arranged side by side on the second mounting bracket along the second direction. The two second adsorption blocks cooperate to adsorb the sheet 100, which can further improve the adsorption stability of the sheet 100 and prevent the sheet 100 from tilting.

[0069] like Figure 7 As shown, in another optional embodiment, the conveying mechanism 1 includes a first conveying section 11 and a second conveying section 12 spaced apart along a first direction, with a regularization station formed between the output end of the first conveying section 11 and the input end of the second conveying section 12. The regularization drive mechanism 3 includes a third adsorption block 33 located below the sheet 100 at the regularization station. The third adsorption block 33 is configured to blow a high-speed airflow at least toward the reference mechanism 2 to create an adsorption area above the third adsorption block 33 for adsorbing the sheet 100, and to drive the sheet 100 toward the reference mechanism 2.

[0070] When the sheet 100 is conveyed from the first conveying section 11 to the straightening station, the third adsorption block 33 located below the sheet 100 at the straightening station blows a high-speed airflow toward the reference mechanism 2. The resulting effect is that, under the Bernoulli effect, an adsorption zone is generated above the third adsorption block 33, allowing the third adsorption block 33 to adsorb and support the sheet 100 passing above it in a non-contact manner. At the same time, because the third adsorption block 33 blows air toward the reference mechanism 2, the adsorbed sheet 100 is pushed toward the reference mechanism 2, so that one side of the sheet 100 is pressed against the straightening reference surface 21, achieving straightening. After straightening, the sheet 100 faces the same direction and is conveyed out through the second conveying section 12.

[0071] Furthermore, by placing the third adsorption block 33 within the gap between the first conveying section 11 and the second conveying section 12, installation space is saved, making the structure of the sheet straightening device of this application simpler. The distance between the first conveying section 11 and the second conveying section 12 can be slightly greater than the length of the sheet 100 in the conveying direction, so that when the sheet 100 is pushed laterally in the straightening position, the sheet 100 will not contact the first conveying section 11 and the second conveying section 12, avoiding wear of the sheet 100 due to friction.

[0072] The third adsorption block 33 can adopt the same structure as the first adsorption block 32 in the previous embodiment. Similarly, two third adsorption blocks 33 can be arranged side by side along the second direction. The two third adsorption blocks 33 cooperate to adsorb the sheet 100, so as to improve the adsorption stability of the sheet 100 and prevent the sheet from tilting.

[0073] like Figure 6 In the illustrated embodiment, the reference mechanism 2 includes a belt extending along a first direction, and the outer side of the belt near the straightening station forms a straightening reference surface 21. Using a belt as the reference mechanism allows the pushed sheet to make flexible contact with the belt, further reducing the risk of sheet damage while ensuring the straightening effect.

[0074] Optionally, the belt is mounted on the drive roller assembly, and the drive roller assembly and belt are driven to rotate by a motor. This ensures that the side of the belt closest to the straightening station is conveyed in the same direction as the sheet 100. This reduces the friction between the sheet 100 and the belt, preventing wear on the sheet 100. Additionally, the belt provides a certain driving force to the sheet 100, propelling it forward and improving straightening efficiency.

[0075] In another optional embodiment, the reference mechanism 2 includes a plurality of rollers spaced apart along a first direction, the outer peripheral surfaces of the rollers facing the regularization station forming a regularization reference surface. By using a plurality of rollers spaced apart along the first direction as the reference mechanism, when the sheet contacts the rollers, the rotating rollers can reduce the frictional force on the sheet, preventing wear. All rollers can be unpowered rollers or powered rollers driven by a motor. Powered rollers can also provide a certain driving force to the sheet 100 to move the sheet 100 forward, improving regularization efficiency.

[0076] The foregoing has provided a sufficiently detailed and specific description of this application. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of this application should fall within the protection scope of this application. The scope of protection claimed in this application is defined by the claims, and not by the above descriptions in the embodiments.
