[0059] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0061] It should be noted that in the description of the present invention, the terms "connection" and "installation" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through an intermediate medium; it can be a mechanical connection or an electrical connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0062] The existing photovoltaic module processing equipment still relies on manual loading and cannot achieve fully automated installation; in addition, the existing photovoltaic module processing equipment cannot achieve assembly line operation and has low processing efficiency.

[0063] Based on this, the present application provides a photovoltaic module processing device, referring to Figure 1 and Figure 2 The device includes a conveying part 1, a lead processing part 2, a wire box installation part 3 and a shell 4, wherein the lead processing part 2, the wire box installation part 3 and part of the conveying part 1 are arranged inside the shell 4; wherein: the conveying part 1 is used to convey the photovoltaic module 100, the lead processing part 2 and the wire box installation part 3 are sequentially arranged above the conveying part 1 along the conveying direction of the conveying part 1; there is a wire box installation position on the upper surface of the photovoltaic module 100, the lead processing part 2 is used to shape the lead at the wire box installation position, and the wire box installation part 3 is used to install the junction box 200 to the wire box installation position.

[0064] During operation, the conveying part 1 conveys the photovoltaic module 100 to the bottom of the lead processing part 2, and the lead processing part 2 shapes the lead at the junction box installation position of the photovoltaic module 100, so that the lead is roughly in a vertical state, which is convenient for the subsequent insertion of the lead into the junction box 200; after the lead shaping is completed, the conveying part 1 conveys the photovoltaic module 100 to the bottom of the junction box installation part 3, and the junction box 200 is installed at the junction box installation position through the junction box installation part 3 to complete the installation of the junction box 200. The above device realizes the fully automated installation of the junction box 200 through the coordinated cooperation of the conveying part 1, the lead processing part 2 and the junction box installation part 3, reducing the labor intensity of manual labor; the lead processing part 2 and the junction box installation part 3 can work synchronously to realize streamlined operation, thereby greatly improving the processing efficiency of the photovoltaic module 100.

[0065] Optionally, the conveying part 1 may be a belt conveying structure, which is a common conveying structure and is not described in detail herein. The conveying part 1 is provided with two correction mechanisms for limiting the position of the photovoltaic module 100, and the two correction mechanisms are respectively provided below the lead processing part 2 and below the wire box installation part 3; when the lead processing part 2 and the wire box installation part 3 are working, the correction mechanism can prevent the photovoltaic module 100 from being offset.

[0066] Reference Figure 3 The wire box installation part 3 includes a plurality of transfer mechanisms 31 and a plurality of wire box picking and placing mechanisms 32, and the plurality of transfer mechanisms 31 and the plurality of wire box picking and placing mechanisms 32 are arranged in a one-to-one correspondence, wherein: the transfer mechanism 31 is used to carry and position the junction box 200; the wire box picking and placing mechanism 32 is used to install the junction box 200 at the corresponding transfer mechanism 31 to the wire box installation position.

[0067] In the above structure, the transfer mechanism 31 can keep the junction box 200 in a specific orientation, so that the wire box pick-up and placement mechanism 32 can accurately clamp the junction box 200 at the transfer mechanism 31 and accurately install the junction box 200 at the wire box installation position, which alleviates the problem that the junction box 200 and the lead wire cannot be accurately aligned due to the position offset of the junction box 200, and improves the installation efficiency of the junction box 200. Compared with the method of manually fixing the junction box 200 in the prior art, the setting of the transfer mechanism 31 not only positions the junction box 200 more accurately, but also does not require manual loading, thereby improving the installation accuracy and efficiency of the junction box 200 and reducing the manual labor.

[0068] Continue to refer to Figure 3 In this embodiment, the number of the transfer mechanism 31 and the number of the junction box placement mechanism 32 are both multiple, so that multiple junction boxes 200 can be installed at the same time, further improving the installation efficiency of the junction boxes 200.

[0069] Reference Figure 4 and Figure 5 The transfer mechanism 31 includes a wire box bearing seat 311 and a wire box positioning structure. The wire box bearing seat 311 is provided with a wire box placement position, and the wire box positioning structure is arranged around the wire box placement position. When working, the wire box placement position is used to place the junction box 200, and the wire box positioning structure is used to position the junction box 200 so that the junction box 200 is kept in a specific orientation.

[0070] Specifically, the wire box positioning structure includes two groups of positioning holes and a pair of wire box clamps 313. The two groups of positioning holes are respectively arranged on opposite sides of the wire box placement position along the length direction, and the two wire box clamps 313 are respectively arranged on opposite sides of the wire box placement position along the width direction. The two groups of positioning holes and the pair of wire box clamps 313 can accurately position the junction box 200 so that the junction box 200 is centered at the wire box installation position.

[0071] On the basis of the above structure, each group of positioning holes includes one or more positioning holes 3111 arranged on the wire box bearing seat 311, and the positioning holes 3111 can play a marking role in the installation of the junction box 200, and prevent the junction box 200 from deviating from the set position. The transfer mechanism 31 also includes a driving source three 312, and the driving source three 312 is installed on the wire box bearing seat 311. The two power output ends of the driving source three 312 are respectively connected to the two wire box clamps one 313. The two wire box clamps one 313 can move toward or away from each other under the drive of the driving source three 312, so as to clamp the junction box 200 at the wire box placement position in the center and keep the junction box 200 in the set position.

[0072] In this embodiment, the transfer mechanism 31 also includes a slide rail 314 and a drive source 315, wherein: one end of the slide rail 314 is located outside the shell 4, and the other end of the slide rail 314 is located inside the shell 4 and close to the conveying part 1 or extends to the top of the conveying part 1; the wire box support seat 311 is slidably set on the slide rail 314, and the drive source 315 is used to drive the wire box support seat 311 to slide back and forth along the slide rail 314.

[0073] When the junction box 200 is loaded, there is no junction box 200 placed on the junction box support seat 311, and the driving source seven 315 drives the junction box support seat 311 to move along the slide rail 314 to the outside of the shell 4, and the junction box installation position is identified by the camera on the loading robot, and then the junction box 200 is placed at the junction box installation position by the loading robot; then, the driving source three 312 drives a pair of junction box clamps one 313 to clamp the junction box 200 to maintain the orientation of the junction box 200; then, the driving source seven 315 drives the junction box support seat 311 to move along the slide rail 314 to close to the conveying part 1 or above the conveying part 1 for clamping by the junction box picking and placing mechanism 32.

[0074] Reference Figure 6The lead processing unit 2 includes a plurality of lead shaping mechanisms 21. In the present embodiment, the number of the lead shaping mechanisms 21 is plural, so that multiple pairs of leads can be shaped at the same time, thereby improving the shaping efficiency of the leads.

[0075] Each lead shaping mechanism 21 includes a lead straightening component 211, a driving component 212 and a visual inspection component 213, wherein: the lead straightening component 211 is installed at the power output end of the driving component 212; the driving component 212 is a three-axis moving structure, which can drive the lead straightening component 211 to move along the three directions of the X-axis, the Y-axis and the Z-axis; the visual inspection component 213 is used to detect the position and shape of the lead at the installation position of the junction box to determine whether the lead is in a vertical state.

[0076] Reference Figure 7 The lead straightening assembly 211 includes two pressing blocks 2111 and two lead claws 2112. The two lead claws 2112 are arranged in the middle of the two pressing blocks 2111, and the two pressing blocks 2111 and the two lead claws 2112 are arranged one by one. A corresponding set of pressing blocks 2111 and lead claws 2112 can move toward or away from each other.

[0077] Specifically, the lead straightening assembly 211 further includes two driving sources 1 2113, which are relatively arranged on both sides of the two pressing blocks 2111, and the power output ends of the two driving sources 1 2113 are respectively connected to the two pressing blocks 2111;

[0078] And / or, the lead wire straightening assembly 211 further includes a second driving source 2114 , and two power output ends of the second driving source 2114 are respectively connected to the two lead wire pushing claws 2112 .

[0079] In this embodiment, the lead straightening assembly 211 also includes a connecting seat 2115, and the driving source 1 2113 and the driving source 2 2114 are both installed on the connecting seat 2115, and the connecting seat 2115 is installed at the power output end of the driving assembly 1 212.

[0080] Reference Figure 8 Each lead wire claw 2112 includes a clamping portion 21121 and a guiding portion 21122 that are connected to each other; the clamping portion 21121 is arranged opposite to the corresponding pressing block 2111, and one end of the guiding portion 21122 away from the clamping portion 21121 extends through the pressing block 2111; the cross-sectional area of ​​the guiding portion 21122 tends to decrease in the direction away from the clamping portion 21121.

[0081] In the above structure, the clamping part 21121 and the pressing block 2111 are arranged opposite to each other, and the two can clamp the lead wire together to shape the lead wire; the end of the guide part 21122 away from the clamping part 21121 has a pointed end, so that the guide part 21122 can be inserted into the middle of a pair of leads. The front end of the clamping part 21121 (i.e., the end close to the guide part 21122) is provided with a chamfer or a rounded corner to further ensure that the lead wire can be smoothly guided to the clamping position.

[0082] In the initial state, the two lead wire pusher claws 2112 are close to each other, and the ends of the guide portions 21122 of the two lead wire pusher claws 2112 away from the clamping portion 21121 form a structure with a substantially triangular longitudinal section. Fig. 9 and Fig.10 When working, the entire mechanism is moved to the rear of a pair of leads, and then the entire mechanism is pushed forward, and the tip of the guide portion 21122 is inserted into the middle of the pair of leads; the entire mechanism continues to be pushed forward, and since the cross-sectional area of ​​the guide portion 21122 increases from front to back, the pair of leads can be pushed apart during the forward movement of the guide portion 21122, thereby guiding the two leads to the two sides of the two clamping portions 21121.

[0083] The provision of the guide portion 21122 is helpful for guiding the inwardly tilted lead to the clamping position, thereby alleviating the problem that the two lead pushers 2112 cannot be smoothly inserted between a pair of leads due to the lead tilting too much inward.

[0084] Continue to refer to Fig. 9 and Fig.10 A groove and a convex strip are respectively provided on the surfaces of the pressing block 2111 and the lead wire claw 2112 which are close to each other, and the convex strip can be inserted into the groove.

[0085] Reference Fig.11 , a protrusion can be squeezed out at the lower end of the lead wire through the groove and the convex strip. When the lead wire is inserted into the junction box 200, the protrusion on the lead wire can enter the junction box 200 through the deformation of the lead wire, and the protrusion on the lead wire can limit the relative position of the lead wire and the junction box 200 to a certain extent, thereby improving the connection strength between the lead wire and the junction box 200, and alleviating the problem of the internal circuit being unstable or even disconnected due to the relative shaking of the lead wire and the junction box 200.

[0086] Reference Fig.12 The lead straightening assembly 211 also includes two guide blocks 2116, which are respectively mounted on two pressing blocks 2111; the guide block 2116 includes a fixing portion 21162 and a conical portion 21161 that are connected to each other, wherein: the fixing portion 21162 is connected to the pressing block 2111; the bottom end of the conical portion 21161 is connected to the fixing portion 21162, and the tip end of the conical portion 21161 is away from the pressing block 2111.

[0087] In this embodiment, the fixing portion 21162 is detachably fixed to the corresponding pressing block 2111 by means of fasteners such as screws. In other embodiments, the guide block 2116 may also be integrally formed with the corresponding pressing block 2111.

[0088] In the above structure, the tapered portion 21161 is used to guide the outwardly inclined lead to between the two pressing blocks 2111, thereby alleviating the problem that the lead cannot smoothly enter between the two pressing blocks 2111 due to the excessive outward inclination of the lead.

[0089] Specifically, a surface of each tapered portion 21161 close to the lead claw 2112 is tilted downward from the pressing block 2111 to the lead claw 2112 , and a surface from the pressing block 2111 to the tip of the tapered portion 21161 is tilted away from the lead claw 2112 .

[0090] Reference Fig.13 and Fig.14 The bottom end of the side of the tapered portion 21161 close to the lead claw 2112 is inclined toward the direction close to the lead claw 2112, which is conducive to pushing the lead inward; the front end of the side of the tapered portion 21161 close to the lead claw 2112 is inclined toward the direction away from the lead claw 2112, thereby increasing the vertical distance between the front end of the tapered portion 21161 and the lead claw 2112, which is conducive to the front end of the tapered portion 21161 being inserted under the expanded lead. The upper end surface of the tapered portion 21161 is inclined downward from the pressing block 2111 to the tip of the tapered portion 21161, the lower end surface of the tapered portion 21161 is horizontally arranged, and the side of the tapered portion 21161 away from the lead claw 2112 is vertically arranged, and the tapered portion 21161 is formed by connecting four planes end to end.

[0091] Continue to refer to Fig.13 and Fig.14 In this embodiment, the lower end surface of the tapered portion 21161 is higher than the upper end surface of the guide portion 21122. Fig.13 and Fig.14 The dotted line in the figure represents the upper end surface of the guide portion 21122. As shown in the figure, since the guide portion 21122 is arranged below the tapered portion 21161, the tapered portion 21161 and the guide portion 21122 will not interfere with each other during the process of the pressure block 2111 and the lead wire claw 2112 clamping the lead wire.

[0092] For the outward-expanding lead, as the mechanism advances forward, the tip of the tapered portion 21161 is first inserted under the outward-expanding lead; as the mechanism continues to advance, the tapered portion 21161 pushes the outward-expanding lead inward, and the lead enters the clamping position along the plane of the tapered portion 21161 close to the lead claw 2112.

[0093] For the retracted lead, as the mechanism moves forward, the tip of the guide portion 21122 is first inserted under the retracted lead; as the mechanism continues to move forward, the lead enters the clamping position along the chamfered or rounded corners of the guide portion 21122 and the front end of the clamping portion 21121.

[0094] The working principle of the lead shaping mechanism 21 is as follows: in the initial state, the two lead claws 2112 are in contact with each other, and the two pressure blocks 2111 are in a retracted state; first, the driving component 212 drives the lead straightening component 211 to move to a position close to the wire box installation position, and the specific position of the lead is detected by the visual detection component 213, and the moving route of the driving component 212 is planned according to the detection result of the visual detection component 213; the lead straightening component 211 is continued to be moved, and under the guidance of the guide part 21122 and the tapered part 21161, a pair of leads at a wire box installation position are respectively located on both sides of the two lead claws 2112, that is, one of the leads is located between a group of pressure blocks 2111 and the lead claws 2112, and the other lead is located at the other between the two pressing blocks 2111 and the lead claws 2112; then, the two driving sources 1 2113 drive the two pressing blocks 2111 to move toward each other, and at the same time, the driving source 2 2114 drives the two lead claws 2112 to move away from each other, and under the clamping force of the two groups of pressing blocks 2111 and the lead claws 2112, a pair of leads are shaped into a vertical state; then, the two driving sources 1 2113 drive the two pressing blocks 2111 to move away from each other, and at the same time, the driving source 2 2114 drives the two lead claws 2112 to move toward each other, releasing a pair of leads; finally, the visual detection component 1 213 detects whether the leads are in a vertical state. After the shape of the leads meets the requirements, the driving component 1 212 drives the lead straightening component 211 to return to its initial state to wait for the next shaping.

[0103] Continue to refer to Fig.16 , the lead clamping assembly 325 is installed on the driving assembly 323; specifically, the driving assembly 323 includes an X-axis moving module 2, a Y-axis moving module 2 and a Z-axis moving module 2, wherein the Y-axis moving module 2 is slidably arranged on the X-axis moving module 2; the lead clamping assembly 325 and the Z-axis moving module 2 are slidably arranged on the Y-axis moving module 2; the wire box clamping group 321, the lead flattening group 322 and the visual inspection assembly 324 are all arranged at the power output end of the Z-axis moving module 2.

[0105] The middle clamping arm 3251 is arranged in the middle of a pair of side clamping arms 3252; the two power output ends of the driving source six 3253 are respectively connected to the two side clamping arms 3252, and are used to drive the two side clamping arms 3252 to move toward each other or away from each other; the power output end of the driving source eight 3255 is connected to the driving source six 3253, and is used to drive the driving source six 3253 to move in a direction away from or close to the lead; the driving source nine 3254 is installed on the Y-axis moving module two, and its power output end is connected to the driving source eight 3255, and is used to drive the driving source eight 3255 to move up and down.

[0106] In the above structure, two opposite leads at the installation position of the wire box can be clamped between the two side clamping arms 3252 and the middle clamping arm 3251, that is, one lead can be clamped between one side clamping arm 3252 and the middle clamping arm 3251, and the other lead can be clamped between the other side clamping arm 3252 and the middle clamping arm 3251. If there is no bulge on the lead, the middle clamping arm 3251 and the side clamping arm 3252 can be clamped on the belly or lower part of the lead; if there is a bulge on the lower part of the lead, the middle clamping arm 3251 and the side clamping arm 3252 can be clamped on the belly of the lead.

[0107] The lead wire clamping assembly 325 can prevent the free end of the lead wire from shaking, so that the free end of the lead wire can be smoothly inserted into the junction box 200 .

[0108] Reference Fig.18 The wire box clamping group 321 includes a driving source 4 3211 and a pair of wire box clamping jaws 2 3212, and two power output ends of the driving source 4 3211 are respectively connected to the two wire box clamping jaws 2 3212;

[0109] The lead wire leveling group 322 is arranged between a pair of wire box clamping jaws 3212, and includes a driving source 5 3221 and a pair of lead wire leveling claws 3222. The power output end of the driving source 5 3221 is connected to the pair of lead wire leveling claws 3222.

[0110] The working principle of the wire box picking and placing mechanism 32 is as follows: first, the driving component 2 323 drives the wire box clamping group 321, the lead leveling group 322, the visual inspection component 2 324 and the lead clamping component 325 to move to a position close to the wire box installation position, and the specific position of the lead is detected by the visual inspection component 2 324, and the moving route of the driving component 2 323 is planned according to the detection result of the visual inspection component 2 324, so that the wire box clamping group 321, the lead leveling group 322 and the lead clamping component 325 are aligned with the lead; then, the driving source 6 3253, the driving source 8 3255 and the driving source 9 3254 drive the middle clamping arm 3251 and the side clamping arm 3252 to clamp a pair of leads at a wire box installation position on both sides of the middle clamping arm 3251, that is, one of the leads is clamped between the middle clamping arm 3251 and one of the side clamping arms 3252, and the other lead is clamped between the middle clamping arm 3251 and the other a side clamping arm 3252; then, the Z-axis moving module 2 drives the lead flattening group 322 and the wire box clamping group 321 to descend. During the descent of the wire box clamping group 321, the upper end of the lead is inserted into the junction box 200. At this time, the lead clamping assembly 325 releases the clamping of the lead, and drives the middle clamping arm 3251 and the side clamping arm 3252 to move in a direction away from the lead through the driving source eight 3255; the Z-axis moving module 2 drives the lead flattening group 322 and the wire box clamping group 321 to continue to descend, and places the junction box 200 on the photovoltaic module 100; at this time, the lead is inserted into the junction box 200 as a whole, and the driving source five 3221 drives a pair of lead flattening claws 3222 to move in opposite directions to flatten a pair of leads; finally, the installation state of the junction box 200 is detected by the visual inspection component 2 324. After the installation state of the junction box 200 meets the requirements, each component is restored to the initial state to wait for the next shaping.

[0111] Reference Fig.19 The lead clamping assembly 325 also includes a push rod 3256 and a driving source +3257. The push rod 3256 passes through the middle clamping arm 3251 and both ends pass through the two side clamping arms 3252 respectively. A lead accommodating groove 32522 is provided on the side of each side clamping arm 3252 close to the middle clamping arm 3251. The driving source +3257 is used to drive the driving source 6 3253 and the two side clamping arms 3252 to move horizontally synchronously in a direction close to or away from the wire box clamping group 321.

[0112] Reference Fig. 20 and Fig.21 The middle clamping arm 3251 is penetrated by a first through hole 32511, each side clamping arm 3252 is penetrated by a second through hole 32521, and the push rod 3256 passes through the second through hole 32521 on one side clamping arm 3252, the first through hole 32511 and the second through hole 32521 on the other side clamping arm 3252 in sequence.

[0113] On the basis of the above structure, the first through hole 32511 is adapted to the outer diameter of the push rod 3256 , and the first through hole 32511 can limit the radial displacement of the push rod 3256 ; the second through hole 32521 is in the shape of a long hole, and part of the push rod 3256 is slidably arranged in the second through hole 32521 .

[0114] In the above structure, the second through hole 32521 reserves the movable space of the push rod 3256; when the two side clamping arms 3252 translate backward, the push rod 3256 will not translate backward with the two side clamping arms 3252 due to the restriction of the first through hole 32511, that is, the radial position of the push rod 3256 remains unchanged during the process of the two side clamping arms 3252 translate backward.

[0115] Furthermore, limiting structures are respectively provided at both ends of the push rod 3256, and the limiting structures prevent the push rod 3256 from coming out of each through hole. Optionally, the limiting structure on the push rod 3256 can be a fastener such as a nut or a bayonet, or a radial protrusion on the push rod 3256. In this embodiment, a radial protrusion is provided at one end of the push rod 3256; the other end of the push rod 3256 passes through each through hole in sequence, and a nut is connected to the part that passes through.

[0116] With the above-mentioned structure, when the two side clamping arms 3252 move toward or away from each other, the push rod 3256 can slide relative to the two side clamping arms 3252 .

[0117] The working principle of the above mechanism is:

[0118] In the initial state, the driving source six 3253 drives the two side clamping arms 3252 to open, and the driving source ten 3257 drives the driving source six 3253 and the two side clamping arms 3252 to be close to the wire box clamping group 321;

[0119] Reference Fig. 20 and Fig.21 , the lead clamping assembly 325 is controlled to move as a whole through the driving device, so that the middle clamping arm 3251 is inserted between the two leads at the installation position of the wire box. At this time, one of the leads is located between one of the side clamping arms 3252 and the middle clamping arm 3251, and the other lead is located between the other side clamping arm 3252 and the middle clamping arm 3251;

[0120] Reference Fig. 22 , continue to push the middle clamping arm 3251 and the two side clamping arms 3252 forward horizontally, thereby driving the push rod 3256 to move forward. If the lead is in a backward tilted state at this time, the push rod 3256 can push the backward tilted lead forward to a vertical state;

[0121] Reference Fig.23Then, the driving source 6 3253 drives the two side clamping arms 3252 to close, and the two leads are clamped between the two side clamping arms 3252 and the middle clamping arm 3251, and are located in the lead receiving grooves 32522 on the two side clamping arms 3252;

[0122] Reference Fig.24 Then, the driving source ten 3257 drives the driving source six 3253 and the two side clamping arms 3252 to move in a direction away from the wire box clamping group 321 (i.e., move backward). If the lead wire is in a forward tilted state at this time, the front side groove wall of the lead wire accommodating groove 32522 can push the forward tilted lead wire backward to a vertical state; Fig.24 As shown, the front and rear ends of the lead are clamped between the front groove wall of the lead accommodating groove 32522 and the push rod 3256, and the two sides of the lead along the thickness direction are clamped between the groove bottom of the lead accommodating groove 32522 and the middle clamping arm 3251, so it will not move, which is convenient for the subsequent installation of the junction box.

[0123] It should be noted that the above-mentioned driving sources can be one of a pneumatic cylinder, an electric cylinder or an oil cylinder, and a pneumatic cylinder is preferably used as the driving source. The above-mentioned driving assembly can also adopt other structural forms, such as a three-axis or six-axis robot structure, and the configuration of the driving assembly only needs to be able to move the corresponding mechanism to a set position.

[0124] In summary, the photovoltaic module processing device provided by the present application realizes the fully automated installation of the junction box 200 through the coordinated cooperation of the conveying part 1, the lead processing part 2 and the junction box installation part 3, and can perform streamlined operations, reduce the labor intensity, and greatly improve the processing efficiency of the photovoltaic module 100.
