Description

Technical Field

DETAILED DESCRIPTION

[0040] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0041] like Figure 2-Figure 15 As shown, this embodiment provides a fabricated photovoltaic bracket connector forming device for welding Figure 1The connector 4 shown comprises a set of spaced vertical plates 1, the upper ends of which are connected to a common horizontal plate 2. Through holes 3 are provided at each end of the horizontal plate 2, and the through holes 3 are at the same distance from the corresponding vertical plates 1. The device comprises an assembly circular table 10, and its outer peripheral wall is sequentially provided with a vertical plate loading portion 20, a horizontal plate loading portion 30, a removal portion 40, and a welding assembly 50 disposed between the horizontal plate loading portion 30 and the assembly circular table 10.

[0042] Specifically, such as Figure 2 As shown, the assembly platform 10 comprises a rotating drum 11 and an assembly base 12. The opening of the rotating drum 11 is vertically oriented. A rotating motor with an output end facing vertically upward is coaxially mounted at the center of the bottom surface of the rotating drum 11. The motor housing is connected to the ground or a frame. Four assembly bases 12 are provided and evenly distributed in a circular array and connected to the outer circumference of the rotating drum 11.

[0043] Specifically, such as Figure 2-Figure 3 、 Figure 8-Figure 9 As shown, the assembly seat 12 includes a rotating shaft 121, a connecting plate 122, a U-shaped seat 123, and a pressing piece 126. The axis of the rotating shaft 121 is arranged along the radial direction of the rotating drum 11 and is located on the center line of the height direction of the rotating drum 11. The connecting plate 122 is connected to one end of the rotating shaft 121 in the middle of one side of the rotating drum 11, and the other end of the rotating shaft 121 passes through the wall of the rotating drum 11 and is connected to the output end of the driving motor. The housing of the driving motor is fixedly connected to the inner wall of the rotating drum 11.

[0044] The U-shaped seat 123 is located on the side of the connecting plate 122 away from the drum 11, with two symmetrically arranged U-shaped seats 123 corresponding to each connecting plate 122. The openings of the U-shaped seats 123 face the ends of the connecting plate 122, and the end surfaces of the openings of the U-shaped seats 123 are flush with the ends of the connecting plate 122. The middle vertical section of each U-shaped seat 123 is vertically recessed downward to form a U-shaped groove 125. The opening depth of the U-shaped groove 125 is less than the length of the vertical plate 1, and the top surface of the U-shaped groove 125 is open and connected to the upper side surface of the horizontal portion of the U-shaped seat 123. The distance between adjacent sides of the two U-shaped grooves 125 is consistent with the width of the rectangular rod cross section.

[0045] like Figure 10 As shown, the inner wall of the U-shaped groove 125 is provided with a receiving cavity 128 on the surface of the opening toward the U-shaped seat 123, and a square hole 129 is provided on one side of the receiving cavity 128. The square hole 129 is connected to the inner wall of the horizontal portion of the U-shaped seat 123, as shown in FIG. Figure 11As shown, the pressing member 126 includes a pressing plate 1261, a square rod 1262, a first spring 1263, and a first circular plate 1264. The pressing plate 1261 is vertically arranged in the U-shaped groove 125, and the outer dimensions of the pressing plate 1261 are adapted to the inner wall dimensions of the accommodating cavity 128. The square rod 1262 is passed through the square hole 129, and one end of the square rod 1262 is connected to the middle of a side of the pressing plate 1261 facing the accommodating cavity 128. The first spring 1263 is passed through the square rod 1262, and one end of the first spring 1263 abuts the pressing plate 1261, and the other end abuts one side of the accommodating cavity 128. The first circular plate 1264 is arranged at one end of the square rod 1262 passing through the square hole 129.

[0046] Avoidance holes 1221 are symmetrically provided on the connecting plate 122, and the avoidance holes 1221 are horizontally arranged along the opening direction of the U-shaped seat 123. A horizontally arranged strip hole 127 is provided in a length direction of the square rod 1262 toward the first circular plate 1264. The strip hole 127 corresponds to the front of the avoidance hole 1221, and the strip hole 127 and the avoidance hole 1221 are located in the same plane.

[0047] like Figure 2 、 Figure 6-Figure 7 As shown, the vertical plate loading unit 20 includes a bracket 21, a first conveyor belt 22, a pusher 23, a vertical plate 24, and a cylinder 25. The bracket 21 includes two parallel and spaced-apart strips 211, each having a U-shaped cross-section. One end of the strip 211 facing the side of the rotating drum 11 is provided with an opening 212, and the length of the opening 212 is greater than the length of the vertical plate 1. Two first conveyor belts 22 are provided, arranged along the length of the strip 211, for conveying the vertical plates 1, so that the length of the vertical plates 1 is consistent with the conveying direction of the first conveyor belts 22. The distance between the two vertically distributed first conveyor belts 22 is consistent with the distance between the two U-shaped grooves 125 on the same connecting plate 122. The side of the strip 211 facing the rotating drum 11 is provided with an arc-shaped notch 214, which is concentric with the rotating drum 11 and corresponds to the end of the first conveyor belt 22 in the conveying direction. The arc-shaped notch 214 is used to avoid the assembly seat 12 when the rotating drum 11 rotates.

[0048] The cylinder 25 is mounted on a frame, with the output end of the cylinder 25 oriented vertically toward the side of the bracket 21 away from the drum 11 and corresponding to the end of the first conveyor belt 22 in the conveying direction. The vertical plate 24 is rectangular and vertically mounted at the output end of the cylinder 25. Two ejectors 23 are symmetrically arranged vertically along the height of the vertical plate 24. The ejectors 23 include a push rod 231, an L-shaped plate 232, a push plate 233, a first inclined surface 234, and an intercepting plate 235. The push rod 231 and the L-shaped plate 232 are located on either side of the long axis of the vertical plate 24, with the L-shaped plate 232 located diagonally above the push plate 233 in the conveying direction of the first conveyor belt 22. The length of the L-shaped plate 232 is greater than that of the push rod 231. One end of the push rod 231 is connected to the vertical plate 24, and the other end is inserted into one side of the strip frame 211. A groove 213 corresponding to the opening 212 is recessed into the other side of the inner wall of the strip frame 211. The groove 213 corresponds to the arc-shaped notch 214. A push plate 233 is positioned corresponding to the groove 213, and its dimensions match the dimensions of the recessed position of the groove 213. Its thickness matches the depth of the recessed position of the groove 213. The side of the push plate 233 facing the vertical plate 24 is connected to the end of the push rod 231 that extends into the strip frame 211.

[0049] The L-shaped plate 232 is arranged horizontally, and the first inclined surface 234 is arranged at one end of the horizontal part of the L-shaped plate 232 and is inclined in the direction of the inner right angle of the L-shaped plate 232. One end of its vertical part is connected to the vertical plate 24, and the horizontal part extends into the strip frame 211. The inner right angle of the L-shaped plate 232 on the upper side faces upward, and the inner right angle of the L-shaped plate 232 on the lower side faces downward. When the opening of the U-shaped groove 125 is rotated to a horizontal state toward the incoming direction of the first conveyor belt 22, the horizontal part of the L-shaped plate 232 corresponds to the avoidance hole 1221.

[0050] One end of the intercepting plate 235 is perpendicularly arranged at one end of the pushing plate 233 toward the direction of the first conveyor belt 22, and the other end is passed through the vertical part of the outer side of the strip frame 211, which is used to intercept the next vertical plate 1 entering the end of the conveying direction of the first conveyor belt 22 when the vertical plate 1 is pushed into the U-shaped groove 125.

[0051] Preferably, in order to improve the stability of the movement of the L-shaped plate 232, a first ear plate is provided vertically upward on the outer side of the top surface of the upper strip frame 211, and a second ear plate is symmetrically provided vertically downward on the bottom surface of the lower strip frame 211, so that the horizontal part of the upper L-shaped plate 232 is passed through the first ear plate, and the lower L-shaped plate 232 is passed through the second ear plate.

[0052] When the vertical plate 1 is transported to the end of the first conveyor belt 22 along the first conveyor belt 22, an assembly seat 12 on the rotating drum 11 rotates to a vertical state, and the opening of the U-shaped groove 125 is directed towards the incoming direction of the first conveyor belt 22. When the assembly seat 12 rotates with the rotating drum 11 to the front of the arc-shaped notch 214, the cylinder 25 is started to move the push rod 231 and the L-shaped plate 232 toward the assembly seat 12, and the push rod 231 pushes the push plate 233 so that the push plate 233 pushes the vertical plate 1 into the corresponding U-shaped groove 125. In the process of pushing the vertical plate 1, the horizontal part of the L-shaped plate 232 corresponds to the lower part of the first inclined surface 234 and inserts the end of the square hole 129 exposed in the square hole 129, and under the action of the first inclined surface 234, the square rod 1262 is pulled out toward the opening of the U-shaped seat 123, so that the pressing plate 1261 remains in the accommodating cavity 128, thereby preventing the vertical plate 1 from entering the U-shaped groove 125. When the vertical plate 1 moves toward one side of the arc-shaped notch 214 to the arc-shaped notch 214, the front end of the horizontal part of the L-shaped plate 232 is inserted into the avoidance hole 1221, which not only allows the pressure plate 1261 to remain in the accommodating cavity 128 before the vertical plate 1 enters the U-shaped groove 125, but also ensures that the two U-shaped grooves 125 are in a horizontal state, thereby avoiding failure of the vertical plate 1 to be pushed into the U-shaped groove 125.

[0053] like Figure 2 、 Figure 12-13 As shown, the transverse plate loading part 30 includes a second conveyor belt 31, a door frame 32, a support rod 33, and a mounting plate 34. The conveying direction of the second conveyor belt 31 is consistent with the conveying direction of the first conveyor belt 22, and the conveying direction of the second conveyor belt 31 is opposite to the center of the rotating drum 11, and is used to convey the transverse plate 2. When conveying, the width direction of the transverse plate 2 is consistent with the conveying direction of the second conveyor belt 31. A blocking plate is laterally provided at the end of the conveying direction of the second conveyor belt 31, which is used to stop the transverse plate 2 conveyed to the end of the conveying direction of the second conveyor belt 31.

[0054] The door frame 32 is arranged across the end of the conveying direction of the second conveyor belt 31. The support rod 33 is vertically connected to the center of the horizontal part of the door frame 32 and faces the direction of the rotating drum 11. The bottom surface of the support rod 33 is provided with a first telescopic rod 331 sliding along its length direction. The first telescopic rod 331 is vertically arranged and a strip plate 332 is provided at the lower end. The length direction of the strip plate 332 is parallel to the horizontal direction of the door frame 32. The bottom surface of the strip plate 332 is parallel and spaced apart with two suction cups 333. When the vertical plate 1 enters the U-shaped groove 125, the L-shaped plate 232 and the push plate 233 exit the U-shaped seat. When the second conveyor belt 31 is turned 123, the connecting plate 122 rotates upward so that the opening of the U-shaped groove 125 is vertically upward. When the rotating drum 11 drives the assembly seat 12 carrying the vertical plate 1 to move to the front of the second conveyor belt 31, the first telescopic rod 331 moves to the top of a horizontal plate 2 at the end of the conveying direction of the second conveyor belt 31. The first telescopic rod 331 is vertically downward so that the suction cup 333 sucks the top surface of the horizontal plate 2 to lift the horizontal plate 2, and then the first telescopic rod 331 is retracted upward, and then moved along the support rod 33 toward the rotating drum 11 to move the horizontal plate 2 to the top surface of the vertical plate 1 for splicing.

[0055] Preferably, in order to improve the accuracy of the splicing position of the horizontal plate 2 and reduce the error, the upper horizontal and vertical sections of the two corresponding U-shaped seats 123 on the same connecting plate 122 are symmetrically provided with positioning holes 124, the diameter of the positioning holes 124 is consistent with the diameter of the through hole 3, and circular holes are provided at both ends of the strip plate 332. The diameter of the circular hole is smaller than the diameter of the positioning hole, and positioning members 334 are vertically penetrated in the corresponding circular holes. The positioning members 334 include a first round rod 3341, a second round rod 3342, and a second round rod 3343 from bottom to top. Plate 3344, the diameter of the first round rod 3341 is consistent with the diameter of the positioning hole 124, the diameter of the second round rod 3342 is smaller than the diameter of the first round rod 3341 and consistent with the diameter of the round hole, the second round plate 3344 is located above the second round rod 3342, and the diameter of the second round plate 3344 is larger than the diameter of the first round rod 3341, and a second spring 3343 is provided on the outer sleeve of the second round rod 3342, the upper end of the second spring 3343 abuts the bottom surface of the second round plate 3344, and the lower end abuts the top surface of the strip plate 332.

[0056] Mounting plates 34 are vertically provided on both sides of one end of the support rod 33 facing the rotating drum 11. The length direction of the mounting plate 34 is parallel to the horizontal part of the door frame 32. A second telescopic rod 341 is vertically provided at the lower end of the mounting plate 34 away from the support rod 33. The second telescopic rod 341 is vertically arranged, and a pressing plate 342 is provided at the lower end of the second telescopic rod 341. When the assembly seat 12 carrying the vertical plate 1 moves to the front of the second conveyor belt 31, the pressing plate 342 is located above the positioning hole 124.

[0057] When in use, the suction cup 333 sucks the top surface of the horizontal plate 2, and the first round rod 3341 is respectively inserted into the corresponding through holes 3 at both ends of the corresponding horizontal plate 2. Then the first telescopic rod 331 is retracted upward to suck the horizontal plate 2 vertically upward, and then the horizontal plate 2 is transferred to the top surface of the vertical plate 1 for splicing. At this time, the positioning piece 334 is located between the pressing plate 342 and the positioning hole 124.

[0059] like Figure 2 、 Figure 14 As shown, the picking part 40 includes a vertical rod 41, a pull plate 42, a slide rail 43, a horizontal rod 44, and a pull plate 45. The slide rail 43 is arranged along the normal direction perpendicular to the rotating drum 11. The lower end of the vertical rod 41 is slidably connected to the slide rail 43. The pull plate 45 is arranged on the side of the vertical rod 41 facing the rotating drum 11. One is vertically provided on both sides of the middle part of the vertical rod 41. The pull plate 45 is vertically arranged along the upper end of the vertical rod 41 facing the rotating drum 11.

[0060] The pulling plate member 42 includes a strip rod 421 and two right-angled trapezoidal plates 422, and the length of the right-angled trapezoidal plates 422 is greater than the length of the strip rod 421. One end of the strip rod 421 is connected to the upper end of the vertical rod 41 facing the rotating drum 11, and the pulling plate 45 is vertically telescopically arranged at the other end of the strip rod 421; the right-angled side of one side of the right-angled trapezoidal plate 422 is perpendicularly connected to the outer end of the cross bar 44 facing the rotating drum 11, and the hypotenuse of the right-angled trapezoidal plate 422 is arranged opposite to a right-angled side connecting the cross bar 44, and the hypotenuse gradually approaches the long axis centerline direction of the vertical rod 41.

[0061] Specifically, such as Figure 15As shown, a rectangular stepped hole 4211 is vertically provided at one end of the strip rod 421 facing the rotating drum 11, and the large end of the rectangular stepped hole 4211 faces upward, and the pull plate 45 includes a second inclined surface 451, a rectangular block 452, a rectangular rod 453, a third spring 454, and a rectangular plate 455. The outer dimensions of the rectangular block 452 are adapted to the inner wall dimensions of the large end of the rectangular stepped hole 4211. The second inclined surface 451 is provided on the side of the rectangular block 452 facing the rotating drum 11 and is inclined to the side away from the rotating drum 11, and the top surface height of the rectangular block 452 is higher than the connecting The height of the horizontal plate 2 on the component 4, the outer wall size of the rectangular rod 453 is adapted to the lower end size of the rectangular stepped hole 4211, the lower end of the rectangular rod 453 passes through the lower end of the rectangular stepped hole 4211 and extends vertically downward from the strip rod 421, the rectangular plate 455 is provided on the rectangular rod 453 passing through the lower end of the strip rod 421, the third spring 454 is sleeved on the rectangular rod 453, and the upper end of the third spring 454 abuts against the lower end of the rectangular block 452, and the lower end of the third spring 454 abuts against the connection between the large end and the small end of the rectangular stepped hole 4211.

[0062] When the spliced ​​connector 4 rotates with the drum 11 to the front of the vertical rod 41, the vertical rod 41 is driven to move toward the drum 11, so that the strip rod 421 passes under the horizontal plate 2 of the connector 4, and under the obstruction of the horizontal plate 2, the rectangular block 452 is vertically downwardly accommodated in the large end of the rectangular stepped hole 4211.

[0063] The extension and retraction of the first telescopic rod 331 , the second telescopic rod 341 , the third telescopic rod 54 and the column 52 can all be achieved by using electric telescopic rods.

[0064] Specific usage process:

[0065] Start the first conveyor belt 22 and the second conveyor belt 31, start the corresponding driving motor in the assembly seat 12 on the side away from the conveying direction of the second conveyor belt 31 to rotate the rotating shaft 121 downward 90 degrees toward the side where the second conveyor belt 31 is located, so that the U-shaped groove 125 is rotated to a horizontal state, start the rotating drum 11, so that the rotating drum 11 transfers the assembly seat 12 after rotating 90 degrees to the front of the arc-shaped notch 214 corresponding to the bracket 21, start the cylinder 25, so that the cylinder 25 pushes the vertical plate 24 to move in the direction of the bracket 21, so that the upper and lower push plates The output member 23 moves synchronously, allowing the two L-shaped plates 232 to pass through the corresponding strip holes 127 along the corresponding first and second lug plates and then into the avoidance hole 1221, allowing the pressure plate 1261 to enter the accommodating cavity 128. Simultaneously, the push plate 233 pushes the vertical plate 1 at the end of the second conveyor belt 31 in the conveying direction into the corresponding U-shaped groove 125. During this process, the first spring 1263 is compressed, and the intercepting plate 235 moves directly in front of the next vertical plate 1 in the conveying direction to intercept the vertical plate 1 and prevent it from interfering with the push plate 233 when the push plate 233 returns to its original position. When the vertical plate 1 is fully entered into the U-shaped groove 125, the output end of the cylinder 25 enters the return stroke, causing the L-shaped plates 232 to sequentially exit the avoidance hole 1221 and strip hole 127, allowing the pressure plate 1261 to press the vertical plate 1 entered into the U-shaped groove 125. Simultaneously, the push plate 233 enters the groove 213, causing the next vertical plate 1 to move directly in front of the push plate 233.

[0066] Start the rotating drum 11 again, and simultaneously start the driving motor corresponding to the assembly seat 12 carrying the vertical plate 1, so that the rotating shaft 121 rotates 90° in the opposite direction upward, so that the U-shaped groove 125 carrying the vertical plate 1 opens upward and is in a vertical state. As the rotating drum 11 rotates, the assembly seat 12 carrying the vertical plate 1 is transferred to the front of the second conveyor belt 31.

[0067] Start the first telescopic rod 331 and move it along the length direction of the support rod 33 to just above a horizontal plate 2 at the end of the conveying direction of the second conveyor belt 31. Then extend the first telescopic rod 331 vertically downward so that the suction cup 333 sucks the position between the two through holes 3 on the horizontal plate 2, and at the same time insert the first round rod 3341 into the corresponding through hole 3. In addition, in order to make the height of the first round rod 3341 exposed from the top surface of the horizontal plate 2 consistent with the height when the suction cup 333 is sucked after the first round rod 3341 is inserted into the through hole 3, through holes for avoiding the first round rod 3341 are respectively opened on both sides of the end of the conveying direction of the second conveyor belt 31.

[0068] When the suction cup 333 completes sucking the horizontal board 2, the first telescopic rod 331 is retracted vertically upward and moves along the support rod 33 to just above the assembly seat 12 carrying the vertical board 1, and then vertically downward so that the bottom surface of the horizontal board 2 is placed on the upper end of the vertical board 1 in the two U-shaped grooves 125.

[0069] Then, the second telescopic rod 341 is extended vertically downward so that the pressing plate 342 presses the second circular plate 3344 vertically downward, thereby moving the second circular rod 3342 vertically downward, and the first circular rods 3341 are respectively inserted into the corresponding positioning holes 124, so that the placement position of the horizontal plate 2 is more accurate. At this time, the suction cup 333 keeps pressing the horizontal plate 2.

[0070] Then, the column 52 is raised vertically upward, and the third telescopic rod 54 is moved toward the joint of the horizontal plate 2 and the vertical plate 1, and the rotary motor 55 is started to adjust the angle of the welding gun 51 so that the welding end of the welding gun 51 is welded to the joint of the horizontal plate 2 and the vertical plate 1, thereby forming the connecting piece 4.

[0071] After welding is completed, the third telescopic rod 54 retreats backward, and the column 52 moves vertically downward out of the rotation track of the assembly base 12.

[0072] Finally, start the rotating drum 11, so that the assembly seat 12 carrying the connecting part 4 rotates with the rotating drum 11 to the front of the vertical rod 41, so that the vertical rod 41 moves toward the assembly seat 12 along the length direction of the slide rail 43, and the rectangular block 452 moves downward to the rectangular stepped hole 4211 under the blocking action of the second inclined surface 451 of the horizontal plate 2. At the same time, the right-angled trapezoidal plate 422 passes through the strip hole 127 and is inserted into the avoidance hole 1221. When the rectangular block 452 moves directly under the horizontal plate 2, it extends vertically upward from the rectangular stepped hole 4211 under the action of the third spring 454. At this time, the top surface of the rectangular block 452 is higher than the top surface of the horizontal plate 2. At this time, the pressure plate 1261 enters the accommodating cavity 128 to release the limit on the vertical plate 1.

[0073] The vertical rod 41 then moves in the opposite direction along the length direction of the slide rail 43, so that the rectangular block 452 pulls the horizontal plate 2, so that the vertical plates 1 on both sides of the connecting member 4 move out of the corresponding U-shaped groove 125 and move out along the top surface of the strip rod 421, thereby realizing automatic discharging, and so on.

It should be understood by those skilled in the art that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
