Description

Technical Field

[0001] The utility model relates to the technical field of film pasting, in particular to a continuous horizontal film pasting machine for photovoltaic modules. Background Art

[0002] In many film pasting operations, it is necessary to attach a tape to the surface to be pasted. However, due to different working objects, the working conditions vary slightly. In a film pasting process, a large number of adhesive films need to be pasted along the width direction of the photovoltaic module. Therefore, generally, many film pasting components arranged in parallel are used to complete the operation at one time. However, if the spacing between these adhesive films is very small, or even the center distance of the adhesive films is less than the width of the film pasting component, it cannot be completed at one time.

[0003] Chinese Patent CN220549261U discloses a film pasting machine for photovoltaic modules, which can place the photovoltaic module by using the platform module and complete the film pasting by the relative movement of the platform module with respect to the film pasting module. A plurality of film pasting modules are arranged side by side, so a large number of adhesive films can be pasted at one time. However, there is a limit to the center distance of the adhesive films here, because the width of the film pasting module is always greater than the width of the adhesive film. Therefore, the spacing between the adhesive films cannot be further reduced, and the film pasting operation with relatively small requirements for the adhesive film spacing cannot be realized.

[0004] Therefore, it is necessary to design a new adhesive film pasting device to solve the above problems. Summary of the Invention

[0010] Specifically, both the first translational adsorption unit and the second translational adsorption unit include an adsorption table, a plurality of alignment mechanisms located on the four sides of the adsorption table, and an X-direction walking mechanism located at the bottom of the adsorption table. The adsorption table sucks air upward.

The first gear meshes with the X-direction rack.

[0012] Furthermore, both the first lifting and conveying unit and the second lifting and conveying unit include a bracket, three synchronous belt lines fixedly arranged in parallel on the bracket, and a first lifting mechanism for driving the bracket to lift relative to the machine frame. The lifting transfer rack includes three support beams and a second lifting mechanism for driving the three support beams to lift synchronously. Each synchronous belt line on the first lifting and conveying unit and the second lifting and conveying unit is coaxial with a support beam in the X axis; the adsorption table is divided into a plurality of adsorption areas with equal height, and the range of the adsorption area avoids the synchronous belt line and the support beam.

[0013] Specifically, both the first horizontal synchronous film pasting unit and the second horizontal synchronous film pasting unit include a fixed frame located on the machine frame, a lifting frame movably connected to the fixed frame along the Z axis, and a plurality of the film pasting components arranged at equal intervals along the Y axis on the lifting frame. A plurality of Z-direction slide rails are arranged on the fixed frame, and Z-direction sliders cooperating with the Z-direction slide rails are arranged on the back of the lifting frame. A synchronous lifting mechanism for controlling the height of the lifting frame is also arranged on the fixed frame.

[0014] Further, a Z - direction induction piece is arranged on the Y - direction side of the lifting frame, a high - position inductor and a low - position inductor are arranged on the Y - direction side of the fixed frame, the high - position inductor and the low - position inductor are used to detect the passing of the Z - direction induction piece, and the synchronous jacking mechanism determines the staying height of the lifting frame by using the signals output by the two Z - direction inductors.

Detailed implementation mode

[0032] The present utility model will be further described in detail below in conjunction with specific embodiments.

[0033] Embodiment:

[0034] As Figure 1 shown, a continuous horizontal film - sticking machine for photovoltaic modules of the present utility model includes a frame 1, a first lifting and conveying unit 2a, a second lifting and conveying unit 2b, a lifting transfer frame 3, a first translation and adsorption unit 4a, a second translation and adsorption unit 4b, a first horizontal synchronous film - sticking unit 5a and a second horizontal synchronous film - sticking unit 5b; the frame 1 is sequentially divided into a first working station, a second working station and a third working station along the X direction. The first horizontal synchronous film - sticking unit 5a and the first lifting and conveying unit 2a are arranged at the first working station, the second horizontal synchronous film - sticking unit 5b and the lifting transfer frame 3 are arranged at the second working station, and the second lifting and conveying unit 2b is arranged at the third working station; the first lifting and conveying unit 2a, the second lifting and conveying unit 2b, the lifting transfer frame 3, the first translation and adsorption unit 4a and the second translation and adsorption unit 4b are arranged at the lower part of the frame 1. The first translation and adsorption unit 4a moves back and forth between the first lifting and conveying unit 2a and the lifting transfer frame 3, and the second translation and adsorption unit 4b moves back and forth between the second lifting and conveying unit 2b and the lifting transfer frame 3; the first horizontal synchronous film - sticking unit 5a and the second horizontal synchronous film - sticking unit 5b are arranged at the upper part of the frame 1, and a plurality of film - sticking components 53 are arranged side by side in the Y direction on both of them. The film - sticking positions of the film - sticking components 53 on different horizontal synchronous film - sticking units are staggered.

[0035] This device is used for horizontally laminating photovoltaic modules, that is, the laminating direction is the width direction of the photovoltaic module, and the adhesive film will be arranged side by side along the length direction of the photovoltaic module. The first lifting and conveying unit 2a is used to feed the photovoltaic module into the device, the second lifting and conveying unit 2b is used to send the photovoltaic module out of the device, and the lifting transfer rack 3 serves as the transfer position for the photovoltaic module to be transferred from the first translational adsorption unit 4a to the second translational adsorption unit 4b. The first station is the station where the first horizontal synchronous adhesive application unit 5a performs the first synchronous adhesive application. The position of the first horizontal synchronous adhesive application unit 5a remains unchanged, and the first translational adsorption unit 4a pulls out the adhesive film by adsorbing and translating the photovoltaic module; the second station is the station where the second translational adsorption unit 4b performs the second synchronous adhesive application. The position of the second horizontal synchronous adhesive application unit 5b remains unchanged, and the second translational adsorption unit 4b pulls out the adhesive film by adsorbing and translating the photovoltaic module. If the laminating positions are sorted in the Y direction, the serial numbers of the adhesive films can be marked as 1, 2, 3... N, where N is the total number of adhesive films. Then the serial numbers of the adhesive films pasted by the first horizontal synchronous adhesive application unit 5a are 1, 3, 5... and the serial numbers of the adhesive films pasted by the second horizontal synchronous adhesive application unit 5b are 2, 4, 6.... If N is an odd number, the Nth adhesive film is pasted by the laminating component 53 on the first horizontal synchronous adhesive application unit 5a; if N is an even number, the Nth adhesive film is pasted by the laminating component 53 on the second horizontal synchronous adhesive application unit 5b. Generally, N is taken as an even number. In this way, the laminating distance is not limited by the width of a single laminating component, and the overall laminating work is continuously completed in two steps, meeting the need for laminating with a relatively close interval and having high work efficiency.

[0036] As Figure 2 shown, the first translational adsorption unit 4a includes an adsorption table 41, several alignment mechanisms 42 located on the four sides of the adsorption table 41, and an X-direction walking mechanism 43 located at the bottom of the adsorption table 41. The adsorption table 41 sucks air upward. The second translational adsorption unit 4b has the same structure as the first translational adsorption unit 4a and will not be elaborated here.

[0037] The alignment mechanism 42 is an alignment wheel driven by a cylinder, with one on each of the Y-direction two sides of the adsorption table 41 and two on each of the X-direction two sides. After the photovoltaic module is in place on the adsorption table 41, all the alignment wheels move inward to position the photovoltaic module before laminating.

[0038] As Figures 2 to 4 shown, two X-direction slide rails 11 and an X-direction rack 12 are provided at the bottom of the frame 1. A number of sliders cooperating with the X-direction slide rails 11 are provided at the bottom of the adsorption table 41. The X-direction walking mechanism 43 includes a first servo motor 431 provided at the bottom of the adsorption table 41 and a first gear 432 driven by the first servo motor 431. The first gear 432 meshes with the X-direction rack 432.

[0039] The transmission mode of the gear and rack is more suitable for translational work with relatively large loads, and the running speed is relatively stable, avoiding the misalignment of the photovoltaic modules on the adsorption table 41. It can also be replaced by components such as screw and nut sleeves.

[0040] As Figures 2 to 4 shown, both the first lifting and conveying unit 2a and the second lifting and conveying unit 2b include a bracket 21, three synchronous belt lines 22 fixedly arranged in parallel on the bracket 21, and a first lifting mechanism 23 for driving the bracket 21 to lift relative to the frame 1. The lifting transfer frame 3 includes three support beams 131 and a second lifting mechanism 132 for driving the three support beams 131 to lift synchronously. Each synchronous belt line 22 on the first lifting and conveying unit 2a and the second lifting and conveying unit 2b is collinear with one support beam 131 along the X-axis; the adsorption table 41 is divided into several adsorption areas 411 with the same height, and the range of the adsorption area 411 avoids the synchronous belt line 22 and the support beam 131.

[0041] The synchronous belt line 22 and the support beam 131 have the freedom of lifting respectively, and the first translational adsorption unit 4a and the second translational adsorption unit 4b have the freedom of translational movement in the X direction. The upper surface of the adsorption table 41 is the conveying surface of the first translational adsorption unit 4a and the second translational adsorption unit 4b. When they translate, the height of the upper surface of the adsorption table 41 remains unchanged; while the synchronous belt line 22 can be lifted or lowered under the drive of the first lifting mechanism 23, and the support beam 131 can be lifted or lowered under the drive of the second lifting mechanism 132. When the synchronous belt line 22 rises, the photovoltaic module falls on the synchronous belt line 22 and detaches from the adsorption table 41, and the first translational adsorption unit 4a or the second translational adsorption unit 4b can move away from or move under the photovoltaic module; when the synchronous belt line 22 descends, the photovoltaic module falls on the adsorption table 41. When the support beam 131 rises, the photovoltaic module falls on the support beam 131 and detaches from the adsorption table 41; when the support beam 131 descends, the photovoltaic module falls on the adsorption table 41.

[0042] As Figures 5 to 8 shown, both the first horizontal synchronous gluing unit 5a and the second horizontal synchronous gluing unit 5b include a fixed frame 51 located on the frame 1, a lifting frame 52 movably connected to the fixed frame 51 along the Z-axis, and a plurality of film pasting assemblies 53 arranged equidistantly on the lifting frame 52 along the Y-axis. A plurality of Z-direction sliding rails 511 are provided on the fixed frame 51, and Z-direction sliding blocks 521 cooperating with the Z-direction sliding rails 511 are provided on the back of the lifting frame 52. A synchronous jacking mechanism 54 for controlling the height of the lifting frame 52 is also provided on the fixed frame 51.

[0043] When the photovoltaic module is translated with the first translational adsorption unit 4a or the second translational adsorption unit 4b, the film pasting assembly 53 needs to be raised a certain distance first to prevent the photovoltaic module from being knocked crooked or knocked off; when the photovoltaic module has reached below the film pasting assembly 53, the film pasting assembly 53 is then pressed down so that the film pasting operation can start.

[0044] As Figure 6 shown, a Z-direction induction piece 521 is provided on the Y-direction side of the lifting frame 52, and a high-position sensor 512 and a low-position sensor 513 are arranged at different heights on the Y-direction side of the fixed frame 51. The high-position sensor 512 and the low-position sensor 513 are used to detect the passing of the Z-direction induction piece 521, and the synchronous jacking mechanism 54 determines the staying height of the lifting frame 52 by using the signals output by the high-position sensor 512 and the low-position sensor 513.

[0045] The cooperation of the two sensors and the Z-direction induction piece 521 realizes the accurate control of the height of the lifting frame 52, so as to orderly control the lifting of the film pasting assembly 53.

[0046] As Figure 6 and Figure 8 shown, a plurality of Y-direction slide rails 522 and a Y-direction rack 523 are provided on the lifting frame 52. Y-direction sliders 521 matching the Y-direction slide rails 522 are provided on the lifting frame 52. A second servo motor 55 is provided on each film pasting assembly 53, and a second gear 56 driven by the second servo motor 55. The second gear 56 meshes with the Y-direction rack 523.

[0047] Each film pasting assembly 53 adjusts its Y-direction position by relying on the second servo motor 55, which can improve the automation level of the equipment and does not require manual adjustment of the positions of the film pasting assemblies 53 one by one.

[0048] The working process of this equipment is as follows: The first translational adsorption unit 4a is first located at the first working station, and the second translational adsorption unit 4b is located at the third working station. The film applying assemblies 53 of the first lateral synchronous film applying unit 5a and the second lateral synchronous film applying unit 5b rise. At this time, the Z-direction sensing piece 524 is detected by the high-position sensor 512. The conveying surface of the synchronous belt line 22 of the first lifting and conveying unit 2a is higher than the adsorption table 41 of the first translational adsorption unit 4a. The synchronous belt line 22 of the first lifting and conveying unit 2a moves the photovoltaic module into the first working station. Subsequently, the synchronous belt line 22 of the first lifting and conveying unit 2a descends below the upper surface of the adsorption table 41 of the first translational adsorption unit 4a, and the photovoltaic module will fall onto the adsorption table 41. The alignment mechanism 42 around it completes the position positioning and then retracts. The adsorption table 41 sucks the photovoltaic module. The film applying assembly 53 of the first lateral synchronous film applying unit 5a descends and presses on the photovoltaic module. At this time, the support beam 131 is at a low position. The first translational adsorption unit 4a drives the photovoltaic module to move towards the second working station until the film applying assembly 53 leaves the photovoltaic module and descends. The Z-direction sensing piece 524 is sensed by the low-position sensor 513, and then the film applying assembly 53 returns to the high position. Subsequently, the support beam 131 rises to a position where its upper surface is higher than the adsorption table 41 of the first translational adsorption unit 4a, and the photovoltaic module is lifted. Then the first translational adsorption unit 4a retracts to the first working station, and the second translational adsorption unit 4b translates to the second working station. The support beam 131 descends, and the photovoltaic module falls onto the adsorption table 41 of the second translational adsorption unit 4b. Similarly, after the photovoltaic unit is aligned, it is sucked. The film applying assembly 53 of the second lateral synchronous film applying unit 5b descends and presses on the photovoltaic module. At this time, the support beam 131 is at a low position. The second translational adsorption unit 4b drives the photovoltaic module to move towards the third working station until the film applying assembly 53 leaves the photovoltaic module and descends. The Z-direction sensing piece 524 is sensed by the low-position sensor 513, and then the film applying assembly 53 returns to the high position. The synchronous belt line 22 of the second lifting and conveying unit 2b rises, and the photovoltaic module leaves the adsorption table 41 of the second translational adsorption unit 4b and falls onto the synchronous belt line 22 of the second lifting and conveying unit 2b. The second translational adsorption unit 4b leaves the third working station, and the synchronous belt line 22 of the second lifting and conveying unit 2b descends again. Subsequently, the synchronous belt line 22 moves the photovoltaic module out of the equipment.

[0049] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the inventive concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
