Technical Field
[0001] This invention relates to the field of component processing technology, and more specifically to a device for processing internal components of a junction box. Background Technology
[0002] Appendix Figure 1 and Figure 2 The photovoltaic element 4, housed inside the junction box, includes a first conductive terminal 41, a diode 42, and a second conductive terminal 43. The diode 42 is positioned between the first conductive terminal 41 and the second conductive terminal 43. Both the first conductive terminal 41 and the second conductive terminal 43 include an end plate 44 and inner and outer abutment plates 45 and 46, respectively, offset from each other on the side walls of the end plate 44. When processing the photovoltaic element 4, the electrodes 421 at both ends of the diode 42 must first be bent. Positioning fixtures are used to position the first conductive terminal 41, the second conductive terminal 43, and the bent diode 42, respectively, so that the electrodes 421 at both ends of the diode 42 are engaged between the inner and outer abutment plates 45 and 46, and the components are then welded together. This process requires repeated positioning of the component, resulting in low efficiency. In particular, the bent electrode 421 is difficult to manually and quickly position accurately between the inner and outer abutment plates 45 and 46 in one go, leading to low processing efficiency for the photovoltaic element 4.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0031] like Figures 1 to 6 As shown, the present invention provides a device for processing internal components of a junction box, including a bending mechanism 1, a positioning mechanism 2, a driving mechanism 3, and a discharge port 20 located on one side of the bending mechanism 1.
[0032] The bending mechanism 1 is used to bend the electrodes 421 at both ends of the diode 42. It includes a mounting block 101, a guide groove 110 formed in the middle of the mounting block 101, a sliding block 102 slidably disposed on the guide groove 110 by a reset spring 105, and a pressure block 109 driven by a power mechanism and disposed opposite to the sliding block 102. A U-shaped groove 103 is provided on the inner side of the sliding block 102. The groove width of the U-shaped groove 103 is equivalent to the diameter of the tube section 422 of the diode 42.
[0033] The sliding block 102 is provided with baffles 111 on both sides of the U-shaped groove 103. The distance between the two baffles 111 is equivalent to the width of the tube section 422 of the diode 42. The baffles 111 are provided with clearance grooves 112 that are equivalent to the width of the electrode 421.
[0034] A flexible clamping block 104 is provided inside the U-shaped groove 103. The flexible clamping block 104 is an arc-shaped rubber clamping block that opens towards the U-shaped groove 103 and can flexibly clamp the tube section 422 when squeezed by the tube section 422 of the diode 42.
[0035] The mounting block 101 has bending grooves 106 on both sides of the upper opening of the guide groove 110 in the middle. The sidewalls of the bending grooves 106 form the outer blocks 107 when the electrodes 421 at both ends of the diode 42 are bent.
[0036] The positioning mechanism 2 consists of a set of movable locking blocks 201 disposed on both sides of the bending mechanism 1, used to respectively lock the conductive terminal 41 and the conductive terminal 43. The conductive terminal 41 and the conductive terminal 43 can slide out from the inner side of the corresponding movable locking block 201. The outer wall of the inner abutment plate 45 of the conductive terminal 41 and the conductive terminal 43 locked in the corresponding movable locking block 201 is located inside the corner side wall of the bent electrode 421.
[0037] The driving mechanism 3 drives the two movable blocks 201 towards the bending mechanism 1, positioning the conductive terminals 41 and 43 on the movable blocks 201 on both sides of the diode 42 and completing the welding. It then drives the welded photovoltaic element 4 away from the bending mechanism 1 and unloads it at the unloading port 20. Specifically:
[0038] The driving mechanism 3 includes a first guide rod group 301 disposed on one side of the bending mechanism 1 parallel to the moving direction of the sliding block 102, and a second guide rod group 305 disposed outside the first guide rod group 301 perpendicular to the moving direction of the sliding block 102. A first guide rail plate 302 driven to move by a first cylinder 303 is slidably mounted on the first guide rod group 301. Two moving blocks 201 are respectively slidably disposed at both ends of the first guide rail plate 302. A sliding clamping rod 304 is also disposed on the moving block 201 parallel to the moving direction of the sliding block 102. Two second guide rail plates 306 connected to each other by compression springs 307 are slidably mounted on the second guide rod group 305. The sliding clamping rods 304 are respectively slidably connected to the second guide rail plates 306. The two second guide rail plates 306 are driven by the push plate assembly to move away from or towards each other.
[0039] The push plate assembly includes a first wedge block 308 disposed opposite to the inner side of the second guide plate 306 and a second wedge block 309 cooperating with the first wedge blocks 308 on both sides. The second wedge block 309 is connected to a vertically guided lifting rod 310. A drive gear 311 is provided on one side of the lifting rod 310 and meshes with a rack on the side wall of the lifting rod 310. A translation rod 312 is installed above the drive gear 311 and has a rack on its bottom surface that meshes with it and is horizontally guided to move. A power plate 108 is connected to one end of the translation rod 312 near the bending mechanism 1. The pressure block 109 is installed on the power plate 108. The power plate 108 is driven to move by the second cylinder 313.
[0040] The working principle of the device of this invention is as follows:
[0041] To facilitate understanding, the principle section will begin with the unloading process of the photovoltaic element 4 after welding:
[0042] I. Unloading of photovoltaic components:
[0043] During unloading, the two moving blocks 201 approach each other, and the diode 42 near the center of the conductive terminal 41 and conductive terminal 43 on them are welded together to form a complete photovoltaic element 4.
[0044] Driven by the first cylinder 303, the first guide plate 302 is limited and slidable by the movable clamping block 201, which clamps the welded photovoltaic element 4 and moves it toward the unloading port 20. The pipe section 422 disengages from the flexible clamping block 104 inside the sliding block 102 under the action of external force.
[0045] Once the U-shaped groove 103 of the sliding block 102 is cleared, the diode 42 can be loaded. Specifically, the diode 42 segments 422 are snapped between the U-shaped groove 103 and the baffle 111. In the initial state, the segments 422 are not squeezed to the flexible clamping block 104, and the electrodes 421 at both ends of the segments 422 are limited in the clearance grooves 112 of the baffle 111.
[0046] Afterwards, the second cylinder 313 drives the power plate 108 to move towards the bending mechanism 1. The rack on the translation rod 312 connected to the power plate 108 drives the drive gear 311 to rotate counterclockwise. The drive gear 311 drives the lifting rod 310 where the rack is located to move downward. The second wedge block 309 connected to the lower end of the lifting rod 310 drives the second guide rail plates 306 connected to the first wedge blocks 308 on both sides to move away from each other. The sliding clamp rods 304 that are limited on them also move away from each other. The moving block 201 installed on the sliding clamp rod 304 moves away from each other. The photovoltaic element 4 moves away from the moving block 201 and is unloaded from the discharge port 20 in the middle.
[0047] After unloading, the movable card block 201 can load conductive terminal 1 41 and conductive terminal 2 43. Specifically:
[0048] The conductive terminal 41 and the conductive terminal 43 are respectively positioned and locked in the movable locking block 201, so that the inner abutment plate 45 of the two are close to the side of the bending mechanism 1 after positioning.
[0049] II. Bending the diode:
[0050] During the process of the power plate 108 being pushed toward the bending mechanism 1, the pressure block 109 on the power plate 108 first presses against the outside of the electrodes 421 at both ends of the diode 42, and drives the tube section 422 to be pressed toward the sliding block 102. When the sliding block 102 is pressed to the end of the guide groove 110, the tube section 422 is pressed into the flexible clamping block 104 and engaged. The electrodes 421 at both ends are pressed by the pressure block 109 to the stop block 107 of the bending groove 106 and bent.
[0051] III. Positioning Welding:
[0052] At this time, the first cylinder 303 drives the first guide plate 302 to limit the sliding of the movable block 201 on it to move the conductive terminal 41 and the conductive terminal 43 to one side of the bending mechanism 1, so that the conductive terminal 41 and the conductive terminal 43 are close to the two sides of the bending mechanism 1 but do not move towards each other.
[0053] After bending, the second cylinder 313 drives the power plate 108 to move away from the bending mechanism 1, and the pressure block 109 moves away from the surface of the photovoltaic element 4. Under the elastic action of the reset spring 105, the sliding block 102 returns to the initial state, and the tube section 422 of the bent diode 42 is still held by the flexible clamping block 104.
[0054] At the same time, the second wedge block 309 moves away from the surface of the squeezed first wedge block 308. Under the elastic action of the compression spring 307, the second guide plate 306 connected to the first wedge block 308 and the sliding clamp 304 that slides at its upper limit move closer to each other. The conductive terminal 41 and conductive terminal 43 in the movable card block 201 installed thereon move closer to the bent diode 42. Since the outer wall of the inner abutment plate 45 of the conductive terminal 41 and conductive terminal 43 in the corresponding movable card block 201 is located inside the corner side wall of the bent electrode 421. The inner abutment plate 45 cuts into the outside of the bent electrode 421 of the diode 42, thereby displacing the diode 42 away from the flexible clamping block 104. At this time, the diode 42 cannot completely slip out of the flexible clamping block 104, and the reset spring 105 is stretched, so that the electrode 421 of the diode 42 is only pressed into the inner layer of the electrode 421. As the conductive terminal 1 41 and conductive terminal 2 43 are pushed towards the center, the electrode 421 can be just locked between the inner abutment plate 45 and the outer abutment plate 46 to fix the relative positions of conductive terminal 1 41, diode 42 and conductive terminal 2 43. The welding operation between them is completed in this positioning state. The above steps are repeated to complete the positioning welding operation between the remaining photovoltaic elements 4.
[0055] This invention, through the cooperation of bending mechanism 1, positioning mechanism 2, and driving mechanism 3, can simultaneously bend diode 42 and complete the positioning welding between conductive terminal 41, diode 42, and conductive terminal 43, as well as the subsequent unloading of photovoltaic element 4. On the other hand, it can ensure that during the process of conductive terminal 41 and conductive terminal 43 being pushed towards the center, electrode 421 can be precisely fitted between inner plate 45 and outer plate 46, achieving precise positioning. This invention improves the overall efficiency of positioning welding of photovoltaic elements.
[0056] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
