Description

TECHNICAL FIELD

[0001] The present application relates to an automatic device, in particular to a kind of photovoltaic module automatic tape stripping device. BACKGROUND

[0002] Photovoltaic module needs laminator to press together glass, EVA, cell piece, EVA and backboard these layers of material in production process, before laminating, to ensure the installation position of each part of photovoltaic module, generally, before entering laminator, frame around photovoltaic module will be pasted with tape, after laminating, the tape for solidification needs to be torn off.

[0003] Among them, one end of the tape of photovoltaic module frame will be exposed at the edge of photovoltaic module 3cm-5cm (one is to expose the end of the tape, to facilitate the tape to be torn off from the photovoltaic module, without the need for manual to find the end of the tape from the frame of photovoltaic module, and the other is that the length of exposure cannot be too long to affect the normal processing of photovoltaic module), and the exposed part of the four groups of tape around the clock or counterclockwise. In the prior art, the tape is generally manually removed. In the prior art, some automatic devices for tape removal have appeared, such as patent No. 202110760013.9, patent name: double-glass tape stripping machine, although the tape stripping device is disclosed. However, it has the following disadvantages:

[0004] 1. When positioning the product, the product is conveyed by the conveying line, then the product is lifted off the conveying line by the lifting device, and then the lower and upper suction are performed. In this way, the upper and lower suction are needed, the structure is relatively complex, and the cost is also higher;

[0005] 2. Whether the product is lower suction or upper suction, the suction cup needs to move to press against the product, and then the suction is performed. In this way, only the moving distance of the suction cup can be controlled to press against the product, only the moving distance of the suction cup can be controlled, but the contact force of the suction cup to the product cannot be controlled, which is easy to cause certain impact on the corresponding part of the product, and easy to cause damage to the product. At the same time, when the suction cup moves, it only moves fixedly, and after a period of use, the suction cup may be worn, resulting in poor suction effect of the suction cup;

[0006] 3. In the process of tape removal, especially when the tape is just clamped and removed, since the end of the tape leaks out a little, it is extremely easy to pull off the tape, resulting in failure to remove the tape;

[0007] 4. After the tape is rotated and wound, when the tape is detached, due to its own stickiness and the stretching during the winding process, the tape will be tightly wrapped around the rotating surface. When the tape is detached, it will stick to the surface and be difficult to detach completely. In other words, only the tape at the unloading plate is removed, while the tape in other parts of the rotating surface will still stick to it, resulting in poor tape removal effect.

DETAILED DESCRIPTION

[0054] The present application will be further described below in conjunction with the drawings and embodiments:

[0055] Embodiment one: referring to Figures 1-10 A kind of automatic tear tape equipment of photovoltaic module, including rack 1, conveying mechanism 2 being set on rack, product limiting mechanism 3, product alignment mechanism 4 and tear tape device 5, the product alignment mechanism is set in the four around of conveying mechanism;The tear tape device is four groups, the left side of conveying mechanism is feed end, and the right side is discharge end, two groups of tear tape device are set respectively above feed end and above discharge end, and other two groups of tear tape device are set respectively above front side of conveying mechanism and above rear side;

[0056] The conveying mechanism has multiple cavities 6 in the middle, and the product limiting mechanism is installed on the frame inside the cavity; a lifting mechanism is provided at the bottom of the frame, and the bottom of the conveying mechanism is connected to the lifting mechanism. The lifting mechanism pushes the conveying mechanism to move up and down; when the conveying mechanism moves downward, the top surface of the product limiting mechanism is positioned above the top surface of the conveying mechanism; when the conveying mechanism moves upward, the product limiting mechanism retracts into the cavity.

[0057] In this embodiment, during actual use, the lifting mechanism is in the lifting state, and the photovoltaic module enters the conveying mechanism and is conveyed by the conveying mechanism. After being conveyed to the predetermined position, a photoelectric sensor 7 is located on the side wall of the cavity. The detection end of the photoelectric sensor faces upward, and the photoelectric sensor is electrically connected to the lifting mechanism. When the photoelectric sensor detects that the product has arrived, the lifting mechanism drives the conveying mechanism to move downward, so that the product limiting mechanism is above the conveying mechanism. In this way, the bottom surface of the photovoltaic module abuts against the product limiting mechanism. Then, the product alignment mechanism aligns the product, making the product centered. After alignment is completed, the product limiting mechanism limits the bottom of the photovoltaic module, so that the product is fixed. After the product is fixed, four sets of tape-tearing devices move to the side of the photovoltaic module, facing the end of the tape attached to the side of the photovoltaic module. Then, the tape-tearing devices clamp the end of the tape and tear it off from the side of the photovoltaic module. The four sets of tape-tearing devices simultaneously tear off all the tape on all four sides of the photovoltaic module, completing the tape-tearing work. The efficiency is high, the quality is good, and no manual operation is required. After the tape is removed, the tape-tearing device moves away from the photovoltaic module. Then, the product limiting mechanism releases its restriction on the photovoltaic module, and the lifting mechanism lifts the conveying mechanism. The product is then lifted up by the conveying mechanism and sent away, waiting for the next set of products to be sent to the same position for the tape-tearing operation. This cycle continues.

[0058] See Figure 1 , 2 As shown, multiple sets of roller conveyor lines 8 are provided at intervals from front to back at the feed end and the discharge end. When the conveying mechanism is in the upward state, the top surface of the conveying mechanism is flush with the top surface of the roller conveyor line; when the conveying mechanism is in the downward state, the top surface of the conveying mechanism is located below the top surface of the roller conveyor line.

[0059] In the embodiment, the conveying mechanism conveys the product from left to right, conveying belts are arranged on the left side and the right side of the rack, the product is conveyed from the conveying belt on the left side to the right side, the right end of the product enters the roller conveying line on the left side first, and the product is supported by the roller conveying line, when the right end of the product moves to the conveying mechanism, the conveying mechanism has the power to convey the product to the right, when the product moves to the product limiting mechanism, the photoelectric sensor detects, then the conveying mechanism box is lowered, the product limiting mechanism limits the product, and then the work of tearing the adhesive tape is carried out. After the work of tearing the adhesive tape is completed, the conveying mechanism rises, and then continues to convey the product to the right, so that the product is conveyed to the roller conveying line on the right side, and then the product is sent away by the conveying belt on the right side of the rack, and then the left side product is conveyed, and the cycle is repeated.

[0060] Referring to Figures 1-4 As shown in the figure, the conveying mechanism 2 comprises a bracket 21, a driving motor 26 and a plurality of groups of conveying belts 22 arranged in front of each other, the bracket is provided with a transmission shaft 23, the driving motor is connected with the transmission shaft through a belt 24, and the ends of the plurality of groups of conveying belts are arranged on the transmission shaft; a plurality of groups of cavities are arranged on the bracket between adjacent conveying belts; the jacking mechanism comprises at least two groups of jacking electric cylinders 25, the bottom of the jacking electric cylinder is mounted on the rack, the output group of the jacking electric cylinder is connected with the bottom of the bracket, and when the output shaft of the jacking electric cylinder is extended, the bracket moves upward, and the top surface of the conveying belt is arranged above the top surface of the product limiting mechanism; when the output shaft of the jacking electric cylinder is retracted, the top of the product limiting mechanism is arranged above the top surface of the conveying belt. The jacking electric cylinder is arranged to facilitate the control of the speed of the upward and downward movement of the conveying mechanism, and the moving distance is also more accurate. Since the speed of the downward movement of the conveying mechanism is easy to control, the speed of the contact between the photovoltaic module and the product limiting mechanism is easy to control, and damage to the photovoltaic module caused by rapid impact or contact of the product limiting mechanism is prevented.

[0061] In the embodiment, the photoelectric sensor is mounted on the side wall of the cavity in the bracket, and is used to detect whether the product moves to the top of the product limiting mechanism.

[0062] The product limiting mechanism 3 comprises a plurality of groups of suction cups 31, the bottom of each group of suction cups is mounted on the rack in the cavity through a stand 32, the top surface of the suction cup retracts into the cavity when the conveying mechanism moves upward, and the top surface of the suction cup is arranged above the top surface of the conveying mechanism when the conveying mechanism moves downward. Among them, the suction cup is connected through the air pipe and the negative pressure mechanism, and when the negative pressure mechanism is vacuumized, negative pressure can be generated through the suction cup, so as to adsorb and limit the product.

[0063] In the embodiment, the top surface of the conveying belt is conveyed from left to right, the lifting electric cylinder drives the support to ascend and descend, when ascending, the top surface of the conveying belt is above the suction cups, after the product is moved to the position, the output shaft of the lifting electric cylinder is retracted, then the support and the conveying belt move downward, so that the top surface of the conveying belt is below the top surface of the suction cups, so that the product is against the suction cups, temporarily supported by the suction cups, then the product alignment mechanism aligns the product, after alignment, the suction cups generate negative pressure, the product is sucked and fixed by the negative pressure of the suction cups, which is convenient for subsequent adhesive tape tearing work of the product. Of course, after the product is moved to the position, the conveying belt can be paused, the product alignment mechanism is used for alignment, after alignment, the conveying belt is lowered again, so that the product is against the suction cups, and then the product is limited by the suction cups, both of which can be used. After the product adhesive tape tearing work is completed, the suction cups are released from the negative pressure, then the output shaft of the lifting electric cylinder is extended, drives the support and the conveying belt to ascend, so that the conveying belt lifts the product away from the suction cups, then the conveying belt continues to send the product to the discharge end, waits for the next group of products to tear the adhesive tape, and so on.

[0064] By lifting and descending of the conveying mechanism, whether the suction cups are exposed is realized, compared with lifting or descending of the suction cups, the conveying mechanism is descended and the weight of the product is automatically pressed on the suction cups, the product can press the suction cups tightly, which is convenient for quickly vacuumizing and adsorbing the product, improves the adsorption effect and strength, prevents the product from shaking, and also prevents the problem that the product is damaged by lifting of the suction cups (the suction cups are single-point positions, if the suction cups are lifted, a certain suction cup may collide with a certain part of the product to cause damage, and the product is automatically descended with the conveying mechanism, firstly, the speed is relatively slow, and the product itself slowly descending will not cause impact and wear due to contact of a single suction cup).

[0065] Referring to Figures 6-10 As shown in the figure, the adhesive tape tearing device 5 comprises a sliding rail 51, a mounting frame 52 slidingly mounted on the sliding rail, an adhesive tape tearing mechanism 50 mounted on the mounting frame, and a vertical motor 53, the outer side of the sliding rail is provided with a rack 54, the rack is parallel to the sliding rail, the output shaft of the vertical motor is provided with a gear 55, the gear is engaged with the rack; when the vertical motor drives the gear to rotate, the gear and the rack drive the mounting frame to move on the sliding rail.

[0066] The sliding rails arranged above the front side and the rear side of the conveying mechanism are parallel to the conveying direction of the conveying mechanism; the sliding rails arranged above the feeding end and the discharge end are perpendicular to the conveying direction of the conveying mechanism.

[0067] In the embodiment, the tape tearing devices on the front and back sides of the conveying mechanism move horizontally, and the tape tearing devices on the left and right sides of the conveying mechanism move vertically, so that the four sets of tape tearing devices can tear the tape on one side of the product respectively.

[0068] Referring to Figures 6-10 As shown in the figure, the tape tearing mechanism is movably installed on the mounting frame via a connecting frame 56, and the tape tearing mechanism is rotationally connected to the connecting frame. The connecting frame is provided with a rotary driving mechanism 57, which drives the tape tearing mechanism to rotate on the connecting frame.

[0069] The tape tearing mechanism comprises a stand 58, a tape clamping assembly, a tape winding assembly and a tape unloading assembly, which are all installed on the stand 58. The rotary driving mechanism drives the stand to rotate on the connecting frame.

[0070] The tape clamping assembly comprises a clamping cylinder 59 and a clamping jaw 60. The clamping cylinder drives the clamping jaw to open and close.

[0071] The tape winding assembly comprises a first cylinder 61 and a first supporting jaw 62. The first cylinder drives the first supporting jaw to open and close. The clamping jaw is arranged inside the first supporting jaw.

[0072] The tape unloading assembly comprises an unloading cylinder 63 and an unloading piece. The unloading cylinder drives the unloading piece to move up and down.

[0073] In the embodiment, when the clamping cylinder drives the clamping jaw to close, the end of the tape on the side of the product is clamped. Then the first cylinder drives the first supporting jaw to open. The rotary driving mechanism drives the tape tearing mechanism to rotate. Meanwhile, the mounting frame drives the tape tearing mechanism to move along the slide rail. During the movement and rotation, the clamping jaw clamps the end of the tape. When rotating, the tape is wound outside the first supporting jaw, so that the tape is annularly wound on the outer surface of the first supporting jaw. When the tape is completely torn off the surface of the product, the clamping jaw opens to release the end of the tape. Then the first supporting jaw closes to release the support of the annular tape. Since the tape has certain viscosity, it may be stuck on the clamping jaw and the first supporting jaw. Therefore, the unloading cylinder drives the unloading piece to move down, so that the annular tape stuck on the clamping jaw or the first supporting jaw is pushed away and falls into the receiving box, thereby achieving the unloading of the tape and waiting for the next set of products to tear the tape.

[0074] Four sets of receiving boxes 9 are arranged below the rack, and each set of receiving box is arranged below each set of tape tearing device. After the tape is torn off, the tape is unloaded by the unloading piece and falls into the receiving box, which can be cleaned by the operator regularly.

[0075] Referring to Figures 6-10As shown, two groups of adhesive tape winding plates 64 are symmetrically arranged on the outer surface of the first supporting claw, the outer surface of the adhesive tape winding plate is an arc-shaped adhesive tape winding surface, and an outwardly protruding baffle 65 is arranged on the top outer surface of the adhesive tape winding plate;

[0076] A first vertical air cylinder 66 is arranged on the stand, and the output shaft at the bottom of the first vertical air cylinder is connected with the top of the first air cylinder 61;

[0077] When the output shaft of the first vertical air cylinder is in the extended state, the bottom of the adhesive tape winding plate is arranged in a flush manner with the bottom of the clamping claw; when the output shaft of the first vertical air cylinder is in the retracted state, the bottom of the adhesive tape winding plate and the first supporting claw is arranged above the bottom surface of the clamping claw;

[0078] When the output shaft of the unloading air cylinder is in the retracted state, the unloading part is arranged above the bottom of the clamping claw; when the output shaft of the unloading air cylinder is in the extended state, the unloading part is arranged below the bottom of the clamping claw.

[0079] In this embodiment, two groups of arc-shaped adhesive tape winding surfaces are arranged, so that when they rotate, the adhesive tape can be wound on the arc-shaped adhesive tape winding surfaces of the two groups of adhesive tape winding plates, forming a ring structure, so that the adhesive tape is wound, and in the winding process, the adhesive tape can also be torn off from the surface of the product. During rotation, the output shaft of the unloading air cylinder is retracted, and after the adhesive tape is torn off, the output shaft of the unloading air cylinder is extended to push the adhesive tape away from the unloading part. The arrangement of the baffle limits the upward position of the adhesive tape, so that the adhesive tape will be below the baffle, thereby ensuring that the adhesive tape will not be stuck above the adhesive tape winding plate during unloading, and ensuring normal unloading of the adhesive tape.

[0080] Referring to Figures 6-10 As described above, the unloading part is connected with the output shaft at the bottom of the unloading air cylinder through a connecting plate 68, the clamping air cylinder is arranged between the unloading air cylinder and the first air cylinder, and the unloading part includes two groups of unloading rods 69, which are symmetrically arranged outside the clamping claw, and are arranged between the clamping claw and the first supporting claw.

[0081] In this embodiment, the two groups of unloading rods and the connecting plate form a U-shaped structure, which is equivalent to a U-shaped plate, so that the upward and downward movement of the unloading rods does not affect the opening and closing of the clamping claw and the supporting claw.

[0082] Referring to Figures 6-9As shown, the connecting frame is further provided with a material pushing mechanism 70 which is arranged beside the adhesive tape tearing mechanism; the material pushing mechanism comprises a vertical plate 71, a second vertical cylinder 72, a material pushing cylinder 73 and a material pushing plate 74, the outer end of the material pushing plate is connected with the output shaft of the inner end of the material pushing cylinder, the material pushing plate is arranged perpendicularly to the upper slide rail; the top of the vertical plate is connected perpendicularly to the bottom of the connecting frame, the second vertical cylinder is installed on the vertical plate, the middle part of the material pushing cylinder is connected with the output shaft of the bottom of the second vertical cylinder.

[0083] In the embodiment, since the protruding length of the adhesive tape is only 3-5 cm, the length of the protrusion is short, after the clamping jaw clamps the end of the adhesive tape, the first clamping jaw may touch the side wall of the product if it is directly rotated, which affects the normal rotation. Therefore, the clamping jaw needs to move outward and away from the surface of the product by a distance, so that it can rotate normally. However, if the clamping jaw clamps the end of the adhesive tape and directly pulls the end of the adhesive tape outward, since there are too many connections between the adhesive tape and the side of the product, the end of the adhesive tape is easy to be pulled off (for example, the distance between the material pushing mechanism and the adhesive tape clamping assembly is 8-10 cm, and the total length of the product width (the length of the adhesive tape to be removed) is 150 cm, if the material pushing mechanism is not provided, when the end of the adhesive tape is pulled outward to separate from the product, the adhesive tape is an integral structure, so that the adhesive tape is connected to the product surface by at least 30-50 cm, which is an integral structure, and it needs to be pulled off with great effort, which may break the adhesive tape), therefore, through the arrangement of the material pushing mechanism, after the clamping jaw clamps the end of the adhesive tape, the output shaft of the material pushing cylinder is extended, the material pushing plate is abutted on the surface of the adhesive tape on the side of the product, and the clamping jaw is away from the side of the product, in this process, the end of the adhesive tape is torn off from the side of the product, and the place where it is torn off is limited by the material pushing plate, so that the adhesive tape and the product to be removed only have a little distance, which is convenient for tearing, after tearing, the material pushing plate is retracted by the material pushing cylinder, and the output shaft of the second vertical cylinder is retracted, which is away from the product and does not affect the subsequent movement and conveying of the product. In this way, the adhesive tape tearing mechanism moves and rotates without touching the product, and the end of the adhesive tape is also prevented from being pulled off, which ensures the normal tearing of the adhesive tape.

[0084] Referring to Figures 6-9 As shown, the mounting frame is provided with a first slide rail 75 and a first driving mechanism, the first slide rail 75 and the first driving mechanism 77 are arranged perpendicularly to the slide rail, the connecting frame comprises a first connecting frame 78 and a second connecting frame 79;

[0086] The first connecting frame is provided with a first vertical slide rail 80 and a third vertical pneumatic cylinder 81, the second connecting frame is slidably arranged on the first vertical slide rail, and the output shaft of the third vertical pneumatic cylinder is connected with the second connecting frame, so that the third vertical pneumatic cylinder drives the second connecting frame to move up and down above the first vertical slide rail.

[0087] The rotating driving mechanism is installed on the second connecting frame, the top of the stand is rotationally connected with the second connecting frame, and the rotating driving mechanism drives the top of the stand to rotate above the second connecting frame. Wherein the rotating driving mechanism is a vertical motor, the bottom of which is provided with a transmission gear, and the outer surface of the support is provided with a gear disc, the transmission gear and the gear disc are engaged, so that the vertical motor drives the support to rotate, thereby realizing the work of tearing the adhesive tape and rotating and winding the adhesive tape, so that the adhesive tapes are wound together and cannot be adhered to other places. In this embodiment, a rotating air connector is provided for supplying air to the three pneumatic cylinders of the adhesive tape tearing mechanism, without affecting the normal rotation and work of the adhesive tape tearing mechanism.

[0088] The connecting frame includes a first connecting frame and a second connecting frame, the first connecting frame drives the adhesive tape tearing mechanism to move above the mounting frame, so that the adhesive tape tearing mechanism is arranged close to or away from the conveying mechanism, that is, close to or away from the product, and the adhesive tape of the product is torn off. The second connecting frame is used to drive the adhesive tape tearing mechanism to move up and down, so as to be away from the product or at the side of the product, without affecting the conveying of the product, and the adhesive tape can be torn off.

[0089] Referring to Figures 2-5 The product alignment mechanism is four groups, which are evenly distributed around the conveying mechanism, and each group of the product alignment mechanism is arranged opposite to the conveying mechanism;

[0092] In the embodiment, after the product is moved onto the conveying mechanism and conveyed by the conveying mechanism, the position of the product cannot be in the correct position and cannot be in the center of the four groups of adhesive tape tearing devices. Therefore, by arranging the four groups of product alignment mechanisms below the four groups of adhesive tape tearing devices, after the conveying mechanism is lowered and the product is placed on the suction cups (the suction cups are not adsorbed temporarily), or in other words, the conveying mechanism is not lowered, but the conveying mechanism is temporarily stopped to convey the product, each group of second sliding rails is arranged perpendicular to the sliding rails of the upper adhesive tape tearing device, wherein the second driving mechanism is a motor and a ball screw, the motor drives the ball screw to rotate, so as to drive the second support to move on the second sliding rail by the ball screw, to move close to or away from the conveying mechanism (the product). In other words, the output shaft of the fourth vertical air cylinder is first extended, so that the vertical pushing roller moves upward, so as to be opposite to the product, then the second support is moved towards the product, the vertical pushing roller of each group of product alignment mechanisms is in contact with four surfaces of the product, so as to center the product. After the centering is completed, the conveying mechanism is lowered, the product is adsorbed by the suction cups (if the conveying mechanism is lowered first, the product is directly adsorbed by the suction cups), the product is positioned (at the same time, the product alignment mechanism is reset, the vertical pushing roller is lowered, and the subsequent product is not affected to be separated from the conveying mechanism), then the adhesive tape tearing device tears the adhesive tape of the product. After the adhesive tape is torn, the product is sent away, and the next group of products is sent in for the adhesive tape tearing work.
