[0034] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0035] Next, in combination with Figures 1 to 9 , the embodiments of the present utility model will be described.

[0036] According to an embodiment of the present utility model, on the one hand, a feeding device for a junction box is provided, including: a storage mechanism 1, a transfer mechanism 2, a conveying mechanism 3, and a detection unit 4. The transfer mechanism 2 is arranged downstream of the storage mechanism 1, and the transfer mechanism 2 is adapted to remove the junction box stored in the storage mechanism 1 and transfer it downstream. The conveying mechanism 3 is arranged downstream of the transfer mechanism 2, and the conveying mechanism 3 is adapted to receive the junction box conveyed by the transfer mechanism 2 and convey it to the subsequent process. The detection unit 4 is arranged between the transfer mechanism 2 and the conveying mechanism 3, the detection unit 4 is electrically connected to the transfer mechanism 2, the detection unit 4 is adapted to detect the junction box on the transfer mechanism 2, and send the detection result to the transfer mechanism 2, and the transfer mechanism 2 is adapted to adjust the attitude of the junction box according to the detection result.

[0037] The transfer mechanism 2 removes the junction box stored in the storage mechanism and transfers it towards the conveying mechanism 3. During the transfer process, the detection unit 4 detects the attitude of the junction box (such as the front and back of the junction box). When there is an error in the attitude of the junction box, the transfer mechanism 2 compensates for the error, and then places the junction box with the correct attitude on the conveying mechanism 3. The conveying mechanism 3 conveys the junction box to the subsequent process. Therefore, the automatic feeding of the junction box is realized, and the consistency of the attitude of the feeding junction box can be ensured, meeting the usage requirements of the subsequent process.

[0038] It should be noted that the feeding device for the junction box in this embodiment can feed the positive junction box, or feed the negative junction box, or feed the positive junction box and the negative junction box simultaneously.

[0039] In one embodiment, as Figure 1 and Figure 2 shown, the storage mechanism 1 is movably arranged, and the storage mechanism 1 is adapted to approach or move away from the transfer mechanism 2. By movably arranging the storage mechanism 1, the storage mechanism 1 can feed towards the transfer mechanism 2, shortening the moving cooperation time between the transfer mechanism 2 and the storage mechanism 1, and improving the feeding efficiency.

[0040] It should be noted that the storage mechanism 1 can approach or move away from the transfer mechanism 2, that is, the storage mechanism 1 can approach or move away from the conveying mechanism 3. When the transfer mechanism 2 transfers the junction box of the storage mechanism 1 to the conveying mechanism 3, the moving path of the transfer mechanism 2 is smaller, shortening the feeding time.

[0041] It should be noted that, please refer to Figure 1 , the storage mechanism 1 is movably arranged along the transverse direction.

[0042] In one embodiment, as Figure 1 and Figure 2As shown, the storage mechanism 1 includes two placement racks 101, which are arranged relatively spaced apart, and are suitable for placing the positive electrode terminal box and the negative electrode terminal box respectively; the transfer mechanism 2, the conveying mechanism 3 and the detection unit 4 are each provided with two, the two transfer mechanisms 2 are arranged correspondingly to the two placement racks 101, the two conveying mechanisms 3 are arranged correspondingly to the two transfer mechanisms 2, and the two detection units 4 are arranged correspondingly to the two conveying mechanisms 3.

[0043] Two placement racks 101 are used to place the positive electrode junction box and the negative electrode junction box respectively, and two transfer mechanisms 2, conveying mechanisms 3 and detection units 4 are correspondingly provided, so that both the positive electrode junction box and the negative electrode junction box can be automatically loaded.

[0044] It is worth noting that a positive electrode terminal box placed on a placement rack 101 is transferred to a corresponding conveying mechanism 3 by a transfer mechanism 2, and is inspected by a detection unit 4 in the middle; another transfer mechanism 2 is used to transfer a negative electrode terminal box placed on another placement rack 101 to another corresponding conveying mechanism 3, and is inspected by another detection unit 4 in the middle.

[0045] In one embodiment, Figure 1 As shown, the conveying mechanism 3 is a conveying belt conveyor, and two conveying belt conveyors are arranged in parallel.

[0046] In one embodiment, Figure 1 and Figure 9 As shown, the detection unit 4 is a CCD camera. Specifically, the detection unit 4 includes a camera body 401 , a lens 402 and a light source 403 .

[0047] In one embodiment, Figure 2 As shown, the material storage mechanism 1 further includes a material storage driving structure 102, which is transmission-connected to the two placement racks 101, and the material storage driving structure 102 is suitable for driving the two placement racks 101 to move closer to or farther from each other, and the two transfer mechanisms 2, the two conveying mechanisms 3 and the two detection units 4 are all located between the two placement racks 101. The synchronous movement of the two placement racks 101 can be achieved through a material storage driving structure 102, which reduces the use cost of the driving structure and simplifies the overall structure.

[0048] It is worth mentioning that please refer to Figure 1 , driven by the material storage driving structure 102, the two placement racks 101 can move toward the middle position or toward both sides at the same time. Figure 1 When the placement rack 101 located on the left side moves to the right, the placement rack 101 located on the right side moves to the left at the same time; when the placement rack 101 located on the left side moves to the left, the placement rack 101 located on the right side moves to the right at the same time.

[0049] It should be further noted that on each side ( Figure 1 the left side and the right side in) two layers of placement racks 101 can be provided. Correspondingly, there are two material storage driving structures 102, and each material storage driving structure 102 is in transmission connection with two placement racks 101 on the same layer. When the two placement racks 101 on one layer are used for loading materials, the two placement racks 101 on the other layer can be used for preparing materials, realizing continuous loading without stopping the machine.

[0050] In one embodiment, as Figure 2 shown, the material storage driving structure 102 includes a driving part 1021 and a lead screw structure 1022. The driving part 1021 is adapted to drive the lead screw structure 1022 to rotate. The lead screw structure 1022 is formed with two thread segments, and the spiral directions of the two thread segments are opposite. The two placement racks 101 are respectively in threaded connection with the two thread segments. Therefore, when the driving part 1021 drives the lead screw structure 1022 to rotate, under the action of the two opposite thread segments, the two placement racks 101 move synchronously in opposite directions.

[0051] In one embodiment, as Figure 2 shown, the lead screw structure 1022 includes two lead screw bodies 10221. The two lead screw bodies 10221 are respectively arranged on opposite sides of the driving part 1021. The driving part 1021 is in transmission connection with the two lead screw bodies 10221 at the same time, and the two thread segments are respectively arranged on the two lead screw bodies 10221.

[0052] Of course, in other alternative embodiments, the lead screw structure 1022 can be an integrally formed lead screw, and two thread segments with opposite spiral directions are formed on one lead screw. The lead screw is driven to rotate by the driving part 1021.

[0053] In one embodiment, the driving part 1021 is a servo motor and a T-shaped reduction gear in transmission connection.

[0054] In one embodiment, as Figure 2 shown, the material storage mechanism 1 further includes a slide rail 103, and the placement rack 101 is slidably connected with the slide rail 103.

[0055] In one embodiment, as Figures 2 to 5 shown, the placement rack 101 includes a rack body 1011 and a hanging rod 1012. One end of the hanging rod 1012 is connected to the rack body 1011, and the other end of the hanging rod 1012 extends in a direction away from the rack body 1011. A material groove 10121 is formed on the outer periphery of the hanging rod 1012, and a plurality of material grooves 10121 are arranged at intervals along the extending direction of the hanging rod 1012. The wiring box is suspended by the hanging rod 1012, and a plurality of wiring boxes are accommodated through the plurality of material grooves 10121, and adjacent wiring boxes are separated, facilitating the individual removal of each wiring box.

[0056] It should be noted that on the material storage mechanism 1, the junction box is hung in a form, which is convenient for stock preparation and grasping. Further, the junction box can be placed on the hanging rod 1012 manually or by the equipment.

[0057] In one embodiment, as Figure 4 and Figure 5 shown, the outer periphery of the hanging rod 1012 is also provided with avoidance grooves 10122. A plurality of avoidance grooves 10122 are provided, and the plurality of avoidance grooves 10122 are correspondingly and communicatively arranged with a plurality of material grooves 10121. The avoidance grooves 10122 are suitable for the transfer mechanism 2 to extend into. By providing the avoidance grooves 10122, the transfer mechanism 2 can enter the material groove 10121 through the avoidance grooves 10122 to grasp the junction box, which is convenient for material taking.

[0058] In one embodiment, as Figures 1 to 5 shown, a plurality of hanging rods 1012 are arranged at intervals on a placement rack 101.

[0059] In one embodiment, as Figures 6 to 8 shown, the transfer mechanism 2 includes a four-axis drive module 201 and a material taking gripper 202. The four-axis drive module 201 is suitable for driving the material taking gripper 202 to move along the x-axis, y-axis and z-axis and rotate around the z-axis. By driving the material taking gripper 202 to move through the four-axis drive module 201, the material taking, transfer and attitude adjustment of the junction box are realized.

[0060] It should be noted that, please refer to Figure 6 and Figure 7 , the four-axis drive module 201 includes a three-way linear motor and a rotary motor. The three-way linear motor is respectively used to drive the material taking gripper 202 to move along the x-axis, y-axis and z-axis, and the rotary motor is used to drive the material taking gripper 202 to rotate around the z-axis.

[0061] In one embodiment, as Figure 1 shown, the junction box feeding device further includes a feeding mechanism 5. The feeding mechanism 5 is suitable for providing zero-pole junction boxes, and the discharging position of the feeding mechanism 5 is arranged on the same side as the discharging position of the conveying mechanism 3. Using the feeding mechanism 5 to provide zero-pole junction boxes is convenient for simultaneously conveying the positive-pole junction boxes, negative-pole junction boxes and zero-pole junction boxes to the subsequent process.

[0062] It should be noted that in this embodiment, the feeding mechanism 5 can be a flexible vibrating disk.

[0063] When using the wiring box loading device of this embodiment, first, the driving part 1021 drives the two screw rod bodies 10221 to rotate, so that the two placement racks 101 move closer to each other to a predetermined position; then, the four-axis driving module 201 drives the material taking gripper 202 to move, and removes the wiring box on the hanging rod 1012; after that, the four-axis driving module 201 drives the material taking gripper 202 to move the wiring box to the CCD camera, the CCD camera takes a picture of the wiring box, and adjusts the posture of the wiring box through the four-axis driving module 201; finally, the four-axis driving module 201 and the material taking gripper 202 place the wiring box on the conveying mechanism 3, and use the conveying mechanism 3 to convey the wiring box to the subsequent process.

[0064] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
