Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of photovoltaic panel accessory welding, and particularly relates to a photovoltaic panel accessory welding clamp. BACKGROUND

[0002] A photovoltaic panel (also known as a solar panel) is a core component for realizing photoelectric conversion, but to apply it to an actual scene (such as a roof, ground, photovoltaic power station, etc.), the photovoltaic panel needs to be installed on a photovoltaic support, and a series of accessories are needed to assist in installation, fixation, support, and guarantee the normal operation of the photovoltaic support system, among which the ground pile pipe is the most important accessory and is the foundation and root of the photovoltaic support system.

[0003] In the production process of the ground pile pipe, multiple nuts need to be pre-welded at the end of the ground pile pipe to lay a foundation for subsequent assembly with other accessories into a support. In the existing welding operation, the fixation of the ground pile pipe and the placement of the nuts usually adopt a mechanical and manual auxiliary mode: the worker first inserts the ground pile pipe horizontally into the positioning column, adjusts the posture of the initial ground pile pipe so that a certain row of bolt holes in the length direction of the side surface of the ground pile pipe can be centered and upward, and then the locking mechanism on the positioning column fixes the pipe body to determine the initial fixation state of the ground pile pipe; then the worker accurately places the nuts in the bolt hole port, and finally completes the welding through the welding gun.

[0004] However, this operation mode exposes significant defects in actual mass production: 1. The single row of bolt holes on the surface of the ground pile pipe need to be manually adjusted to the upward centered state, and the worker often needs to position and repeatedly calibrate through auxiliary tools, which not only occupies a large amount of working hours, but also is difficult to avoid the positioning deviation caused by visual error or operation deviation, directly affecting the accuracy of subsequent nut placement. 2. The placement of the nuts completely depends on manual operation, and the worker needs to place them one by one after aligning the bolt holes, which not only has high labor intensity and low efficiency, but also may cause nut and bolt hole alignment deviation due to slight negligence, resulting in quality problems such as virtual welding and offset welding after welding, and increasing the rework rate.

[0005] In summary, when dealing with a large number of ground pile pipes for welding, a large amount of time is needed for the fixation of the ground pile pipe and the nut, which reduces the welding quality and greatly prolongs the production cycle.

DETAILED DESCRIPTION

[0028] The following will be described in detail below with reference to the accompanying drawings. Figure 1 - the accompanying drawings Figure 9 The present application will be further described in detail.

[0029] Please refer to the accompanying drawings Figure 1 and Figure 2 A photovoltaic panel accessory welding clamp for use in machining the ground pile pipe 11 in the photovoltaic panel accessory. The clamp comprises a mounting seat 1, a hollow positioning column one 2 is rotatably arranged on the mounting seat 1, a rotating mechanism 3 is arranged between the mounting seat 1 and the positioning column one 2, an alignment and locking mechanism one 4 is arranged on the positioning column one 2, and an alignment and locking mechanism two 5 is arranged above the positioning column one 2.

[0030] In specific work, after the ground pile pipe 11 is sleeved on the positioning column 1, the ground pile pipe 11 is automatically adjusted and locked in the predetermined posture by the adjusting and locking mechanism 1 4, so that the single-row threaded hole 12 on the ground pile pipe 11 can be upwardly and centrally arranged, and the adjusting and locking mechanism 2 5 can first guide and centrally arrange the nut 10 (hexagonal nut in the present scheme) and then adjust and centrally lock the nut 10, so as to cooperate with the external welding equipment to weld the nut 10 and the ground pile pipe 11. When the single-row threaded hole 12 on the ground pile pipe 11 is welded with the nut 10, the rotating mechanism 3 and the adjusting and locking mechanism 1 4 can be rotated by a certain angle (90° in the present scheme), and then the automatic feeding, clamping and fixing of the nut 10 and the welding are repeated, so as to finally complete the welding processing of the ground pile pipe 11. The automatic central fixing and locking of the ground pile pipe 11, the automatic feeding, guiding, central arrangement and locking of the nut 10 are realized.

[0031] Referring to Figure 1 and Figure 2 , the rotating mechanism 3 comprises a motor 1 fixedly arranged on the mounting seat 1, and the output shaft of the motor 1 is in transmission connection with the surface of the positioning column 1 2 through a gear set. The positioning column 1 2 is driven to rotate by the adjusting and locking mechanism 1 4, and the ground pile pipe 1 1 locked by the adjusting and locking mechanism 1 4 is rotated.

[0032] Referring to Figure 2 and Figure 3 , the adjusting and locking mechanism 1 4 comprises a plurality of slide seats 41 which are columnar and can slide along the positioning column 1 2 in the radial direction. The plurality of slide seats 41 at the same position are uniformly distributed in the circumferential direction of the positioning column 1 2. The surface of the positioning column 1 2 is provided with a plurality of slide holes 1 6 corresponding to the threaded holes 1 2 on the surface of the ground pile pipe 1 1. The inner end port position of the slide hole 1 6 is fixedly provided with a guide sleeve. The slide seat 41 is slidingly arranged between the slide hole 1 6 and the corresponding guide sleeve. The slide seat 41 is fixedly provided with two return springs 1 (not shown in the figure) which are symmetrical to the center axis of the slide seat 41 on the port side wall close to the inside of the positioning column 1 2. The other end of the return spring 1 is fixedly connected with the corresponding position of the inner wall of the positioning column 1 2, so as to automatically return after the slide seat 41 loses the pressure of the driving assembly 1 43. The slide seat 41 is provided with an adjusting assembly 1 42 on the end face away from the center axis of the positioning column 1 2. The positioning column 1 2 is provided with a driving assembly 1 43. After the worker sleeves the ground pile pipe 1 1 on the surface of the positioning column, the single-row threaded hole 1 2 on the ground pile pipe 1 1 needs to be roughly aligned with the slide hole 1 6 on the positioning column 1 2, and then the driving assembly 1 43 drives the slide seat 1 41 to move outward, drives the adjusting assembly 1 42 to move towards the inner port of the threaded hole 1 2 on the surface of the ground pile pipe 1 1, forces the ground pile pipe 1 1 to locally fine-tune to centrally adjust the threaded hole 1 2, and the adjusting assembly 1 42 and the inner wall of the inner port of the threaded hole 1 2 generate a certain pressure, so that the positioning column 1 2 and the ground pile pipe 1 1 are relatively locked by the common pressure of the plurality of adjusting assemblies 1 42.

[0033] Referring toFigure 3 and Figure 6 The righting assembly 42 includes two guide blocks one 421 and two guide blocks two 422, which are integrally fixed on the side end face of the slide 41 away from the inside of the positioning column one 2, and the two guide blocks one 421 and the two guide blocks two 422 are evenly staggered along the circumference of the corresponding slide 41. The guide block one 421 and the guide block two 422 are both right triangle structures, and the slopes of the two are different in inclination (the specific inclination is obtained by multiple experiments and calculations by those skilled in the art). The slopes of the two corresponding guide blocks one 421 form a conical guide surface one 7, and the slopes of the two corresponding guide blocks two 422 form a conical guide surface two 8, as shown in Figure 6 When the staff roughly aligns the pile pipe 11 into the positioning column one 2, there is often a condition that the threaded hole 12 and the slide hole one 6 are not accurately aligned. At this time, the drive assembly one 43 drives the slide 41 to move towards the inner port of the corresponding threaded hole 12. Due to the difference in the height of the inner wall of the inner port of the threaded hole 12 at different positions caused by the inaccurate alignment of the threaded hole 12 and the slide hole one 6, the present application can ensure that the slopes of the guide block one 421 and the guide block two 422 can simultaneously abut the inner wall of the inner port of the threaded hole 12 after the slide 41 moves a certain distance, thereby realizing the righting of the threaded hole 12.

[0034] During specific work, the conical guide surface one 7 and the conical guide surface two 8 simultaneously move towards the inner wall of the inner port of the threaded hole 12 under the action of the drive assembly one 43. When the threaded hole 12 and the slide hole one 6 do not completely correspond, they respectively abut the inner wall of the inner port of the threaded hole 12 at different positions and right the threaded hole 12, so that the threaded hole 12 at this position completely corresponds to the corresponding slide hole one 6. At this time, the slopes of the corresponding guide block one 421 and the guide block two 422 respectively abut the inner wall of the inner port of the threaded hole 12 at different positions of this position, and the slopes of all corresponding guide blocks one 421 and guide blocks two 422 at different positions on the positioning column one 2 abut the inner wall of the inner port of the threaded hole 12 at the corresponding position and generate pressure, which together center the pile pipe 11 and lock it on the positioning column one 2. At the same time, if the pile pipe 11 is exactly matched with the threaded hole 12 and the slide hole one 6 when it is inserted into the positioning column one 2, the pile pipe 11 can be centered and locked on the positioning column one 2 without righting.

[0035] Reference Figures 2-4The driving assembly one 43 comprises a driving screw 431 rotatably arranged at the inner center position of the positioning column one 2, a plurality of tapered driving seats 432 are threadedly arranged on the driving screw 431 along the length direction of the driving screw 431, the guide wheels are rotatably arranged on the side end face of the sliding seat 41 close to the driving seats 432, the guide wheels roll against the surfaces of the corresponding driving seats 432, two guide rods are slidably and telescopically arranged between all the driving seats 432, the two ends of the guide rods are fixedly connected with the inner wall of the positioning column one 2, the motor two is fixedly arranged on the end face of the positioning column one 2 away from the mounting base 1, and the output shaft of the motor two is fixedly connected with one end of the driving screw 431. The motor two controls the rotation of the driving screw 431 to drive the horizontal movement of the driving seats 432, and the tapered surfaces of the driving seats 432 roll against the corresponding guide wheels in the horizontal movement process and force the guide wheels to push the sliding seat 41 to move towards the inner port of the corresponding threaded hole 12.

[0036] In specific work, after the staff sets the ground pile pipe 11 on the surface of the positioning column one 2, the single-row threaded hole 12 on the ground pile pipe 11 needs to be roughly aligned with the sliding hole one 6 on the positioning column one 2, then the motor two controls the rotation of the driving screw 431 to drive the horizontal movement of the driving seats 432, the guide block one 421 and the guide block two 422 on the sliding seat 41 are moved towards the inner port of the corresponding threaded hole 12 on the ground pile pipe 11, and finally the two guide block ones 421 and the two guide block twos 422 in the same aligning assembly one 42 are arranged to abut against the inner wall of the inner port of the same threaded hole 12 at different positions, so that the ground pile pipe 11 is aligned with the positioning column one 2 according to the predetermined posture and is fixed on the positioning column one 2, so that the ground pile pipe 11 can be rotated and displaced by the motor one and the gear set.

[0037] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7, the second righting and locking mechanism 5 comprises a storage cylinder 51 connected with an external mobile device and having an open lower end, an inside of the storage cylinder 51 is provided with a storage cavity 9 in a hexagonal cross section, a cylindrical locating post two 52 is fixedly arranged at a middle portion of an upper end of the storage cavity 9, a plurality of sliding holes two extending along a length direction of the locating post two 52 are arranged on a surface of the locating post two 52, the plurality of sliding holes two are uniformly distributed along a circumferential direction of the locating post two 52, a plurality of inner support locking plates 53 which can slide along a radial direction of the locating post two 52 are arranged on the locating post two 52, the inner support locking plates 53 are in sliding connection with the corresponding sliding holes two, two reset springs two symmetrically arranged above and below are fixedly arranged on a side of the locating post two 52 close to an inside of the locating post two 52, the other end of the reset spring two is fixedly connected with a corresponding position of an inner wall of the locating post two 52, so as to automatically reset when the inner support locking plate 53 loses pressure of a driving assembly two 54. The storage cylinder 51 and the locating post two 52 are jointly provided with the driving assembly two 54, and the driving assembly two 54 and the storage cylinder 51 are jointly provided with a righting assembly two 55 for righting the nut 10.

[0038] The storage cylinder 51 can realize up-down movement and horizontal-left and right movement through the external mobile device. When feeding, the nuts 10 are sent into the storage cavities 9 in the inside of the storage cylinder 51 from the lower end of the storage cylinder 51 one by one and are stacked and placed. And each nut 10 is sleeved on the surface of the locating post two 52. Since the storage cavity 9 is in a hexagonal shape, the nut 10 is directly limited after entering the storage cavity 9. When the driving assembly two 54 controls the inner support locking plate 53 to abut against an inner wall of a center hole of the nut 10 in the storage cylinder 51, the nut 10 is coaxially and centrally positioned and locked with the locating post two 52, at this time, the righting assembly two 55 is in an idle state; when the inner support locking plate 53 is unlocked, the righting assembly two 55 simultaneously acts, and righting of the nut 10 is realized by clamping two symmetric plane segments of a peripheral side of the nut 10.

[0039] The second righting and locking mechanism in the application needs to be installed on an existing mobile device (i.e. a mobile platform) when in use. It should be understood by those skilled in the art that any selection or change of the structure, model or control mode of the mobile device itself should be considered to fall within the protection scope of the technical scheme of the application as long as it can drive the clamp to complete the movement function.

[0040] Referring to Figure 2 , Figure 3 , Figure 8 and Figure 9The driving assembly two 54 comprises a driving rotating rod 541 rotatably arranged in the positioning column two 52 through a connecting plate, a plurality of polygonal cams 542 are fixedly arranged on the surface of the driving rotating rod 541, the side of the inner supporting locking plate 53 close to the polygonal cam 542 is arranged as a circular arc surface, the polygonal cam 542 movably abuts against the circular arc surface of the inner supporting locking plate 53, the upper end of the storage cylinder 51 is fixedly provided with a motor three through a support, the upper end of the driving rotating rod 541 movably penetrates the upper end of the storage cylinder 51 and the upper end of the positioning column two 52 and is fixedly connected with the output shaft of the motor three. The motor three controls the rotation of the driving rotating rod 541 to drive the rotation of the polygonal cam 542, each outer convex surface of the polygonal cam 542 respectively abuts against the corresponding circular arc surface of the inner supporting locking plate 53, thereby pushing the inner supporting locking plate 53 to move to the outside of the positioning column two 52, and the plurality of inner supporting locking plates 53 simultaneously move outward to abut against the inner wall of the central hole of all the nuts 10 sleeved on the surface of the positioning column two 52, thereby centrally locking all the nuts 10 in the storage cylinder 51.

[0041] Referring to Figures 2-5 The righting assembly two 55 comprises two swing rods 551 rotatably arranged on the outside of the storage cylinder 51 and symmetrically relative to the center of the storage cylinder 51, the lower end of the swing rod 551 is arranged as a bent section and is fixedly connected with a pushing rod 552, the pushing rod 552 is perpendicular to the swing rod 551, two guide seats 553 are fixedly arranged on the outside of the storage cylinder 51, a strip-shaped guide hole is formed in the guide seat 553, the upper end of the swing rod 551 is slidably arranged in the corresponding strip-shaped guide hole, the upper end of the driving rotating rod 541 is fixedly provided with a driving disc 554, two push-pull plates 555 are hingedly arranged on the surface edge of the driving disc 554, and the end of the push-pull plate 555 away from the driving disc 554 is hingedly connected with the upper end of the corresponding swing rod 551. When the motor three controls the reverse rotation of the driving rotating rod 541 to drive the polygonal cam 542 to abut against the corresponding inner supporting locking plate 53 to lock the corresponding nut 10, at this time, the driving rotating rod 541 simultaneously drives the rotation of the driving disc 554, the driving disc 554 drives the swing rod 551 to rotate through the push-pull plate 555, and the originally horizontal pushing rod 552 swings away from the positioning column two 52, as shown in Figure 9 When the motor three controls the forward rotation of the driving rotating rod 541 to drive the polygonal cam 542 to rotate forward, so that the inner supporting locking plate 53 releases the locking of the nut 10, at this time, the swing rod 551 rotates to drive the pushing rod 552 to move close to the positioning column two 52 and finally abut against the horizontal section of the corresponding nut 10, and the two pushing rods 552 simultaneously abut against the two symmetrical horizontal sections of the nut 10, thereby righting the nut 10, as shown in Figure 3 .

[0042] Need to be particularly pointed out is that the angle of the driving disc 554 rotation and the distance of the swing lever 551 driving the push rod 552 swing, all through the personnel in the technical field through many rounds of repeated experiments, ensure that the driving rotation lever 541 drive the driving disc 554 rotation, the driving disc 554 can be through the push and pull plate 555 drive the swing lever 551 and the push rod 552 corresponding action to the nut 10 for swing right.

[0043] Specific work, the nut 10 in the storage cylinder 51 is locked by each inner support locking plate 53 in multiple directions around the positioning column two 52, at this time the push rod 552 moves away from the positioning column two 52, when each inner support locking plate 53 around the positioning column two 52 simultaneously shrink inward, the push rod 552 synchronously moves towards the positioning column two 52, for the nut 10 placed on the surface of the pile pipe 11 to swing right, as Figure 3 Shown.

[0044] The clamp in the scheme is used with the external welding equipment as follows: the worker puts the end of the pile pipe 11 needing to weld the nut 10 on the surface of the positioning column one 2, and then roughly aligns any one row of thread holes 12 on the surface of the pile pipe 11 with the sliding hole one 6 at the corresponding position on the surface of the positioning column one 2, and then the motor two controls the driving seat 432 to cooperate with the sliding seat 41, so that all the guide blocks one 421 and the guide blocks two 422 move towards the inner wall of the inner port of the corresponding thread hole 12, and the thread hole 12 and the corresponding sliding hole one 6 are swung right through the slope section of the guide blocks one 421 and the guide blocks two 422, and the pressure generated in the swinging right process can relatively lock the pile pipe 11 and the positioning column one 2.

[0045] For the convenience of understanding, the welding direction in the scheme is from right to left. The storage cylinder 51 moves downward under the control of the external moving device to above the first thread hole 12 on the right side of the pile pipe 11, and then the inner support locking plates 53 around the positioning column two 52 simultaneously shrink, so that all the nuts 10 fixed in the storage cylinder 51 simultaneously move downward, until the nut 10 at the lowermost falls to the outer port position of the corresponding thread hole 12 on the upper surface of the pile pipe 11 under the guidance of the inner support locking plates 53, at this time the push rod 552 still exists a certain distance with the nut 10. Then the driving rotation lever 541 further rotates forward, the inner support locking plates 53 further shrink towards the center of the positioning column two 52, so that the swing lever 551 further moves towards the horizontal section around the nut 10, and the two push rods 552 finally abut and clamp the two horizontal sections around the nut 10 symmetrically, so as to swing right the nut 10, and then the driving rotation lever 541 reversely rotates by a certain angle, so that the inner support locking plates 53 move outward from the positioning column two 52 to lock the nut 10 swung right, and then the external welding gun is aligned with the connection between the nut 10 swung right and locked and the pile pipe 11, and rotates to weld with the center of the positioning column two 52 as the circle point.

[0046] After the welding of the nut 10 in a single position is completed, the inner support locking plate 53 is separated from the welded nut 10, and then the storage cylinder 51 drives the inner support locking plate 53 to move upward by a certain height, so that the lower end of the inner support locking plate 53 is in the second nut 10, and then the inner support locking plate 53 is expanded outward again to fix other nuts 10 in the storage cylinder 51. Then the storage cylinder 51 as a whole moves to the left to the upper end of the next threaded hole 12 on the ground pile pipe 11, and the welding operation is repeated.

[0047] When the welding of all the threaded holes 12 in a row on the ground pile pipe 11 is completed, the positioning column one 2 drives the ground pile pipe 11 to rotate 90° through the cooperation of the motor one and the gear set, and the welding operation is repeated again, so that the welding of the nuts 10 on all the threaded holes 12 on the ground pile pipe 11 is completed in a cycle.

[0048] The ground pile pipe 11 is automatically locked through the alignment locking mechanism one 4, the staff only needs to roughly align the threaded hole 12 of the ground pile pipe 11 with the sliding hole one 6 of the positioning column one 2, and the driving assembly one 43 can drive the sliding seat 41 to move outward to drive the alignment assembly one 42 to move outward, and the threaded hole 12 is fine-tuned and aligned by using the different inclination sections of the guide block one 421 and the guide block two 422, and finally the relative locking of the ground pile pipe 11 and the positioning column one 2 is realized through the common pressure of multiple alignment assemblies one 42, which saves the manual repeated calibration steps and solves the problem of time-consuming and easy positioning deviation of the threaded hole 12 of the ground pile pipe 11 in the prior art; in the alignment locking mechanism two 5, the hexagonal storage cavity 9 of the storage cylinder 51 realizes the preliminary positioning of the nut 10, the inner support locking plate 53 can first center-lock the nut 10 in the storage cylinder 51, the inner support locking plate 53 shrinks when discharging, so that the nut 10 is accurately dropped into the position of the threaded hole 12 under the guidance, then the alignment assembly two 55 completes the alignment by clamping the two horizontal sections of the nut 10, and finally the inner support locking plate 53 expands outward again to realize the center locking, realizing the full-automatic discharging, guiding, aligning and locking of the nut 10, replacing manual operation, solving the problems of high labor intensity, low efficiency and easy deviation of the nut 10; through the cooperation of the rotating mechanism 3 and the alignment locking mechanism one 4, the rotating mechanism 3 can cooperate with the alignment locking mechanism one 4 to drive the positioning column one 2 to accurately rotate 90° after the welding of a row of threaded holes 12 is completed, and then the nut 10 discharging, locking and welding process is repeated to realize the circular machining of multiple rows of threaded holes 12, realize the automatic continuous welding of multiple rows of threaded holes 12 on the ground pile pipe 11, and solve the problem of manual adjustment of the pipe body posture multiple times for welding of multiple rows of threaded holes 12. In summary, the coordinated operation of the mechanisms in the scheme improves the degree of automation, reduces manual intervention, ensures the stability of welding, and improves the welding quality.
