DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. 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.

[0029] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0030] Example:

[0031] like Figure 1 and Figure 2 As shown, the photovoltaic cell junction box cover device provided in this embodiment includes a robot arm 1, a gripping component 2 and a visual component 3; the robot arm 1 includes a working end, the gripping component 2 is connected to the working end of the robot arm 1, the gripping component 2 is used to clamp or loosen the cover of the junction box, the robot arm 1 is used to drive the gripping component 2 to move between the preparation area of ​​the cover and the top of the box body of the junction box, and to drive the gripping component 2 to rise and fall; the visual component 3 is connected to the working end of the robot arm 1, the visual component 3 is used to collect image information of the cover or the box body, or, the visual component 3 is used to collect image information of the cover and the box body.

[0032] The photovoltaic cell junction box upper cover device provided in this embodiment is used in the covering process of the solar cell junction box. When covering, the mechanical arm 1 can be started first, so that the mechanical arm 1 drives the grasping component 2 and the visual component 3 to move to the cover preparation area of ​​the junction box, and then the grasping component 2 is started, so that the grasping component 2 grasps the cover of the junction box. When the grasping component 2 moves to the cover preparation area, in order to facilitate the grasping component 2 to grasp the cover, the mechanical arm 1 can also drive the grasping component 2 to descend until the grasping component 2 contacts the cover. After the grasping component 2 grasps the cover, the mechanical arm 1 is used to drive the grasping component 2 to move to the top of the box body of the junction box. At this time, the cover grasped by the grasping component 2 is located above the box body. Then the mechanical arm 1 can be used to drive the grasping component 2 to descend. Since the cover and the box body of the solar cell junction box are usually fixed to each other by a clamping method, after the grasping component 2 drives the cover to descend, the cover can be automatically clamped and fixed on the box body, so that the automatic covering process of the solar cell junction box can be realized.

[0033] After the cover is snap-fitted and fixed on the box body, the visual component 3 can also be used to collect image information of the cover and the box body, so as to facilitate the inspection of whether the cover of the junction box is accurately snap-fitted and fixed on the box body.

[0034] It should be noted that the visual component 3 can not only be used to check whether the junction box cover is in place, but also assist the robot arm 1 and the grasping component 2 in operating when the robot arm 1 drives the grasping component 2 to move and the grasping component 2 grasps the cover. Specifically, the visual component 3 can collect image information of the cover in the preparation area and the box body of the junction box during the movement of the robot arm 1, so that the robot arm 1 can stop moving in time when it moves to the preparation area and above the box body. The visual component 3 can also collect image information of the cover when the grasping component 2 grasps the cover, so that the grasping component 2 can accurately grasp the cover.

[0035] It should also be noted that the cover of the junction box usually has a front side and a back side. During the covering process, only when the front side of the cover is facing away from the box body, that is, only when the front side of the cover is facing upward, can the cover and the box body be successfully snapped together. Otherwise, the cover and the box body cannot be snapped together, and the covering fails. The photovoltaic cell junction box cover device provided in this embodiment can observe whether the cover is facing upward through the visual component 3 when grabbing the cover, and make the grabbing component 2 accurately grab the cover facing upward with the cooperation of the visual component 3, so that the cover moved to the top of the box body is the cover facing upward, effectively ensuring the success rate of the subsequent covering process.

[0036] It can be seen that the photovoltaic cell junction box cover device provided in this embodiment can realize the automatic cover process of the junction box through the mechanical arm 1 and the grasping component 2, without manual operation, which can not only effectively save manpower, but also effectively improve the cover efficiency. And the photovoltaic cell junction box cover device can improve the accuracy of various operations in the cover process through the visual component 3, which can not only improve the success rate of junction box assembly, but also further improve the efficiency of junction box cover.

[0037] Compared with the prior art, the photovoltaic cell junction box cover device provided in this embodiment can realize the automatic snap-fitting and fixing between the cover body and the box body of the junction box through the cooperation between the robot arm 1 and the grasping component 2, without the need for manual operation, thus effectively improving the covering efficiency, and the photovoltaic cell junction box cover device can inspect the junction box after covering through the visual component 3 to determine whether the covering is successfully achieved.

[0038] like Figure 2 As shown, the photovoltaic cell junction box upper cover device provided in this embodiment also includes a lifting drive component 4, which is connected between the working end of the robot arm 1 and the grasping component 2 to drive the grasping component 2 to rise or fall.

[0039] Compared with using the robot arm 1 to drive the grabbing component 2 to rise or fall, setting a lifting drive component 4 between the working end of the robot arm 1 and the grabbing component 2 and using the lifting drive component 4 to drive the grabbing component 2 to rise or fall can effectively simplify the structure of the robot arm 1 and simplify the action design of the robot arm 1. Therefore, in this embodiment, the photovoltaic cell junction box upper cover device preferably also includes a lifting drive component 4, and the lifting drive component 4 is connected between the working end of the robot arm 1 and the grabbing component 2.

[0040] It should be noted that when the lifting drive assembly 4 drives the grabbing assembly 2 to rise or fall, it is not only convenient for the grabbing assembly 2 to grab the cover or release the cover, but also helps the grabbing assembly 2 to avoid obstacles, thereby effectively preventing the cover from being damaged due to collision.

[0041] In this embodiment, the lifting drive assembly 4 can be a drive such as a cylinder, an oil cylinder, an electric push rod or a swing cylinder. In this embodiment, the lifting drive assembly 4 preferably uses a cylinder, and correspondingly, the lifting drive assembly 4 can also include a solenoid valve 40, which is used to control the air intake or air outlet of the cylinder to achieve the extension or shortening of the cylinder.

[0042] like Figure 2As shown, the grabbing assembly 2 includes a driving structure 20, a first clamp 21 and a second clamp 22. The first clamp 21 or the second clamp 22 is connected to the output end of the driving structure 20, or both the first clamp 21 and the second clamp 22 are connected to the output end of the driving structure 20. The driving structure 20 is used to drive the first clamp 21 and the second clamp 22 to move closer to or away from each other to clamp or release the cover body.

[0043] During use, when the driving structure 20 drives the first jaw 21 and the second jaw 22 to move closer to each other, the first jaw 21 and the second jaw 22 can clamp the cover body, thereby realizing the cover body grabbing process; when the driving structure 20 drives the first jaw 21 and the second jaw 22 to move away from each other, the first jaw 21 and the second jaw 22 can relax the cover body, thereby realizing the cover body releasing process.

[0044] When the first clamp 21 or the second clamp 22 is connected to the output end of the driving structure 20, the driving structure 20 may adopt a telescopic driver with an output end such as a cylinder, and at this time, one of the first clamp 21 and the second clamp 22 is connected to the output end of the driving structure 20, and the other clamp remains in a fixed position. During use, the clamp connected to the output end of the driving structure 20 can be driven by the driving structure 20 to move closer to or away from the other clamp, thereby realizing the process of grabbing or releasing the cover.

[0045] When the first clamping jaw 21 and the second clamping jaw 22 are both connected to the output end of the driving structure 20, the driving structure 20 may adopt a driver with two output ends, such as a double-headed cylinder or a pneumatic slide rail with two sliders, and the first clamping jaw 21 and the second clamping jaw 22 are respectively connected to the two output ends of the driving structure 20. During use, the first clamping jaw 21 and the second clamping jaw 22 can be driven by the driving structure 20 to move toward each other or away from each other at the same time, thereby realizing the process of grabbing the cover or releasing the cover.

[0046] It should be noted that the structure of the grabbing assembly 2 is not limited to the above-mentioned form including the driving structure 20, the first clamping jaw 21 and the second clamping jaw 22. The grabbing assembly 2 may also adopt a suction cup structure capable of generating adsorption force. Since the grabbing assembly 2 formed by the driving structure 20, the first clamping jaw 21 and the second clamping jaw 22 has better grasping stability on the cover body than the suction cup structure, the grabbing assembly 2 in this embodiment preferably includes the driving structure 20, the first clamping jaw 21 and the second clamping jaw 22.

[0047] Furthermore, since the pneumatic slide rail has a simple structure and good stability in use, the preferred driving structure 20 in this embodiment is a pneumatic slide rail, which includes a slide rail and a slider that can slide on the slide rail; when there is one slider, the first clamp 21 or the second clamp 22 is connected to the slider; when there are two sliders, the first clamp 21 and the second clamp 22 are respectively connected to the two sliders.

[0048] In addition, in order to improve the installation stability of the driving structure 20 , a slide rail seat 200 may be provided at the position of the lifting driving assembly 4 connected to the grabbing assembly 2 , and the driving structure 20 is installed on the slide rail seat 200 .

[0049] like Figure 2 As shown, a receiving groove 23 is provided at the side wall of the grabbing assembly 2 close to the cover body, and the receiving groove 23 is used to receive the cover body.

[0050] In the process of grabbing the cover body, the receiving groove 23 can limit the cover body, thereby improving the grabbing stability of the grabbing component 2 on the cover body.

[0051] Further, such as Figure 2 As shown, a plurality of protrusions 230 are provided at the side wall of the grabbing assembly 2 close to the cover body, and the plurality of protrusions 230 are sequentially distributed along the circumference of the cover body to form a receiving groove 23 with the side wall of the grabbing assembly 2 .

[0052] Compared to directly digging a receiving groove 23 on the side wall of the grabbing component 2, forming the receiving groove 23 using multiple protrusions 230 and the side wall of the grabbing component 2 can not only ensure the limiting effect of the receiving groove 23 on the cover body, but also reduce the friction between the receiving groove 23 and the cover body, thereby facilitating the grabbing component 2 to release the cover body.

[0053] When the grasping assembly 2 includes a first jaw 21 and a second jaw 22, the first jaw 21 and the second jaw 22 can both adopt a rectangular block structure. At this time, the two top corners of the bottom of the first jaw 21 away from the second jaw 22 are respectively provided with protrusions 230, and the two top corners of the bottom of the second jaw 22 away from the first jaw 21 are respectively provided with protrusions 230. When the first jaw 21 and the second jaw 22 move closer to each other and abut against each other, the two protrusions 230 on the first jaw 21 and the two protrusions 230 on the second jaw 22 can cooperate with the bottom of the first jaw 21 and the bottom of the second jaw 22 to form a receiving groove 23.

[0054] like Figure 2 As shown, the photovoltaic cell junction box upper cover device provided in this embodiment may further include an air suction component, and a negative pressure hole 24 is provided on the side wall of the grabbing component 2 close to the cover body, and the negative pressure hole 24 is connected to the air suction component.

[0055] The suction component is used to inhale or release air, so as to generate or remove adsorption force at the negative pressure hole 24. Specifically, when the gripping component 2 grabs the cover body, the suction component inhales air to generate adsorption force at the negative pressure hole 24, and the adsorption force can further improve the stability of the cover body on the gripping component 2. When the gripping component 2 releases the cover body, the suction component inhales and releases air to remove the adsorption force at the negative pressure hole 24, so that the cover body can be separated from the gripping component 2.

[0056] Further, such as Figure 1 As shown, the photovoltaic cell junction box upper cover device provided in this embodiment may further include a negative pressure gauge 5, which is used to detect the negative pressure at the negative pressure hole 24, so as to facilitate judgment on whether the adsorption force at the negative pressure hole 24 meets the grasping stability requirements.

[0057] like Figure 1 As shown, the photovoltaic cell junction box upper cover device provided in this embodiment also includes a height adjustment component 6, which is connected between the working end of the robot arm 1 and the lifting drive component 4, and is used to adjust the height of the lifting drive component 4 from the ground.

[0058] When a height-adjusting component 6 is connected between the working end of the robot arm 1 and the lifting drive component 4, not only can the height-adjusting component 6 be used to flexibly adjust the height of the lifting drive component 4 from the ground, so that the photovoltaic cell junction box upper cover device is suitable for various working conditions, but also the height-adjusting component 6 can be used to supplement the lifting stroke of the lifting drive component 4, so that the lifting drive component 4 has a wider range of applications.

[0059] Among them, the height-adjusting component 6 can also adopt a telescopic driver such as a cylinder. In order to simplify the structure of the height-adjusting component 6 and reduce its use cost, the height-adjusting component 6 in this embodiment is preferably a lead screw, and the free end of the robotic arm 1 is provided with a threaded hole compatible with the above-mentioned lead screw, and the lead screw is threadedly connected to the threaded hole. At this time, by rotating the lead screw at the free end of the robotic arm 1, the lifting drive component 4 can be driven to rise or fall, thereby realizing the adjustment of the height of the lifting drive component 4 from the ground.

[0060] like Figure 1 and Figure 2 As shown, there are multiple grasping components 2, and the multiple grasping components 2 are divided into two groups, and the two groups of grasping components 2 are symmetrically distributed, and the visual component 3 is arranged between the two groups of grasping components 2.

[0061] The two groups of grasping components 2 enable the photovoltaic cell junction box upper cover device to grasp, transfer and cover multiple covers at the same time, thereby effectively improving the covering efficiency of the photovoltaic cell junction box upper cover device.

[0062] By arranging the visual component 3 between the two groups of grabbing components 2, the visual component 3 can collect image information of the cover or box body below the two groups of grabbing components 2, without the need to arrange multiple visual components 3, thus effectively saving costs.

[0063] The visual component 3 may be a camera or a monitoring device.

[0064] like Figure 1 As shown, a mounting seat 10 is provided at the working end of the robot arm 1 , two sets of gripping components 2 are connected to the mounting seat 10 , and the visual component 3 is installed on the mounting seat 10 .

[0065] The mounting seat 10 can provide support and mounting position for the grabbing component 2 and the vision component 3 , thereby effectively ensuring the mounting stability of the grabbing component 2 and the vision component 3 .

[0066] It should be noted that in the process of assembling the junction box of the solar cell, the box body and the cover body of the junction box are far away from each other after they are produced. If the cover body or the box body is manually moved when the cover is covered, the efficiency is low. Figure 3 and Figure 4 As shown, a conveying assembly 70 can be arranged between the area where the box body is located and the area where the cover body is located. The conveying assembly 70 can replace manual labor to convey the cover body far away from the box body to one side of the box body, thereby effectively improving the assembly efficiency of the junction box.

[0067] The photovoltaic cell junction box upper cover device provided in this embodiment can be arranged in the area where the box body is located. In this case, the end of the conveying component 70 close to the photovoltaic cell junction box upper cover device is the aforementioned material preparation area of ​​the cover body, and the end of the conveying component 70 away from the photovoltaic cell junction box upper cover device is the material loading area of ​​the cover body. When conveying the cover body, the cover body is first placed in the aforementioned material loading area, and then the conveying component 70 is started. When the conveying component 70 conveys the cover body to the material preparation area of ​​the cover body, the conveying component 70 is closed, and then the mechanical arm 1 and the grabbing component 2 in the photovoltaic cell junction box upper cover device are started, so as to transfer the cover body at the material preparation area to the top of the box body.

[0068] The conveying assembly 70 may be composed of a conveyor belt, a pulley and a motor. The motor may be a stepping motor. In this case, the conveying assembly 70 may perform step-by-step conveying on the cover.

[0069] It can be seen that the conveying assembly 70 can cooperate with the photovoltaic cell junction box cover device provided in this embodiment to realize the automatic conveying and covering process of the junction box cover, and further improve the efficiency of the junction box covering.

[0070] In addition, in order to keep the cover of the preparation area facing up to improve the success rate of subsequent capping, Figure 5As shown, a flip cover assembly 71 can be arranged near the cover loading area. The flip cover assembly 71 includes a vibration plate and a vibration driver. The vibration plate is used to hold the cover. The output end of the vibration driver is connected to the vibration plate. The vibration driver is used to drive the vibration plate to vibrate, thereby driving the cover inside to flip.

[0071] Furthermore, a cover visual component 710 may be provided above the vibration plate, and the cover visual component 710 is used to collect image information of the cover in the vibration plate, so as to facilitate observation of whether the cover in the vibration plate is facing up. If the cover in the vibration plate is facing up, the cover can be directly transferred to the conveying component 70; if the cover in the vibration plate is facing down, the vibration driver is started, and the vibration plate is driven to vibrate by the vibration driver, so that the cover in the vibration plate is facing up directly.

[0072] To further improve the cover conveying efficiency, and thus the cover capping efficiency, e.g. Figure 3-Figure 5 As shown, a feeding robot 72 may be further provided between the conveying assembly 70 and the flip cover assembly 71 . The feeding robot 72 is used to pick up the cover body in the vibration plate and transfer the cover body to the conveying assembly 70 .

[0073] like Figure 4 As shown, a cache component 73 can also be provided between the conveying component 70 and the feeding robot 72. The cache component 73 can include a cache seat and a rotary driver. The cache seat is provided on one side of the end of the conveying component 70 which serves as the cover loading area, and the cache seat is provided with a plurality of cache positions distributed in sequence along the width direction of the conveying component 70. The feeding robot 72 can pick up the plurality of cover bodies in the vibration plate in sequence and transfer them to the plurality of cache positions; the output end of the rotary driver is connected to the cache seat, and the rotary driver is used to drive the cache seat to rotate. When the cache seat rotates to be inclined relative to the conveying component 70 and connected to the conveying component 70, the plurality of cover bodies on the cache seat can automatically and simultaneously slide down to the conveying component 70 under the action of gravity.

[0074] It can be seen that the cache component 73 can cooperate with the feeding robot 72 to arrange the multiple cover bodies transferred to the conveying component 70 in an orderly manner, thereby making the multiple cover bodies in the cover body preparation area arranged in an orderly manner, effectively improving the convenience of the subsequent cover body picking process.

[0075] like Figure 3-Figure 5 As shown, a feeding assembly 74 may also be provided on the side of the flip cover assembly 71 away from the feeding robot 72. The feeding assembly 74 includes a hopper, a material channel and a material discharge driving mechanism. One end of the material channel is connected to the hopper, and the other end is arranged above the vibration plate. The hopper is used to hold a plurality of cover bodies, and the material discharge driving mechanism is arranged on one side of the hopper for driving the plurality of cover bodies in the hopper to enter the material channel in sequence.

[0076] During use, the cover in the hopper can enter the material channel by starting the material discharge drive mechanism.
