Description

[0001] The invention relates to a string welding machine, in particular to a welding strip clamping device and a string welding machine. Background Art

[0002] The function of the photovoltaic cell stringer is to press the welding tape and the grid lines of the photovoltaic cell together. When the stringer is working, the head of the welding tape needs to be clamped by a clamping device, so that the welding tape can be pulled out to a preset length under the traction of the traction structure, and then cut by the cutting structure and laid on the grid lines of the cell.

[0041] See also Figure 1 and Figure 2 As shown, a welding ribbon clamping device corresponding to a preferred embodiment of the present invention comprises: a clamping mechanism 100, comprising a first clamping assembly 110, a second clamping assembly 120 and a first elastic member, wherein the first clamping assembly 110 and the second clamping assembly 120 can move toward or away from each other; a first driving mechanism 200, comprising a first transmission assembly 210 located between the first clamping assembly 110 and the second clamping assembly 120 and a first driving cylinder 220 driving the first transmission assembly 210 to rotate; a second driving mechanism 300, comprising a second transmission assembly 310 located between the first clamping assembly 110 and the second clamping assembly 120 and a first driving cylinder 220 driving the first transmission assembly 210 to rotate The second driving cylinder 320 drives the second transmission component 310 to rotate; wherein, when the first driving cylinder 220 and the second driving cylinder 320 are in the extended state, the first clamping component 110 and the second clamping component 120 are suitable for moving toward each other to a closed state under the action of the first elastic member; the second transmission component 310 responds to the contraction of the second driving cylinder 320 to push the first clamping component 110 and the second clamping component 120 to move backwards to a slightly open state, and the first transmission component 210 responds to the contraction of the first driving cylinder 220 to push the first clamping component 110 and the second clamping component 120 to move backwards to a fully open state.

[0042] The present invention adopts the above structure, and the clamping mechanism 100 has a fully open state, a slightly open state and a closed state. When it is necessary to receive the soldering strip, the clamping mechanism 100 can be switched to the fully open state to facilitate the reception of the soldering strip. When it is necessary to perform an assembly operation, the clamping mechanism 100 can be switched to a closed state to clamp the soldering strip. When the soldering strip is pulled out after assembly, the clamping mechanism 100 can be switched to a slightly open state. During the soldering strip pulling process, the clamping mechanism 100 can guide the soldering strip to prevent the soldering strip from deviating and ensure the subsequent welding effect. The state switching of the clamping mechanism 100 is achieved by the first driving cylinder 220 and the second driving cylinder 320 cooperate with each other, the first driving cylinder 220 and the second driving cylinder 320 only need to switch to the extended state or the retracted state, the driving cylinder structure is simple and the switching reliability is good; in addition, the clamping mechanism 100 drives the first clamping component 110 and the second clamping component 120 to move toward each other to the closed state through the first elastic member, and the first driving mechanism 200 and the second driving mechanism 300 only need to provide a thrust to push the first clamping component 110 and the second clamping component 120 to move back to back, which can effectively simplify the structure of the first transmission component 210 and the second transmission component 310 and ensure the reliability during the pushing process.

[0043] Further, the welding strip clamping device includes a mounting seat 400, and the first clamping assembly 110 and the second clamping assembly 120 can be slidably arranged on the mounting seat 400 along the first horizontal direction. A connecting shaft 410 whose axial direction is parallel to the vertical direction is fixed on the mounting seat 400, and the first transmission assembly 210 and the second transmission assembly 310 are rotatably sleeved on the connecting shaft 410. The first driving cylinder 220 is hinged between the mounting seat 400 and the first transmission assembly 210, and the second driving cylinder 320 is hinged between the mounting seat 400 and the second transmission assembly 310. The hinge axis of the first driving cylinder 220 and the second driving cylinder 320 is parallel to the vertical direction. Specifically, a hinge 420 is provided on the mounting base 400, and the hinge 420 corresponds one-to-one to the first driving cylinder 220 and the second driving cylinder 320. The first driving cylinder 220 and the second driving cylinder 320 are placed on the mounting base 400, and the output end of the first driving cylinder 220 is hinged to the first transmission assembly 210, and the cylinder body of the first driving cylinder 220 is hinged to the hinge 420, and the output end of the second driving cylinder 320 is hinged to the second transmission assembly 310, and the cylinder body of the second driving cylinder 320 is hinged to the hinge 420.

[0044] Preferably, the first driving cylinder 220 and the second driving cylinder 320 are arranged opposite to each other in the first horizontal direction, and the connecting shaft 410 is located between the first driving cylinder 220 and the second driving cylinder 320. An accommodating space for accommodating the first transmission assembly 210 and the second transmission assembly 310 is formed between the first driving cylinder 220 and the second driving cylinder 320. By adopting the above arrangement, the first driving mechanism 200 and the second driving mechanism 300 can be made more compact and suitable for installation in a narrow space.

[0045] Further, refer to Figure 3 and Figure 4 As shown, the first transmission assembly 210 and the second transmission assembly 310 are arranged at an axial interval on the connecting shaft 410 so as not to hinder the independent rotation of the two. In this embodiment, the first transmission assembly 210 is located below the second transmission assembly 310, and a shoulder can be set on the connecting shaft 410 to ensure the axial position reliability of the two.

[0046] The first transmission assembly 210 includes a first transmission block 211, a first bearing 212 and a first follower 213. The first transmission block 211 is sleeved outside the connecting shaft 410 and has two opposite push-up ends in the radial direction of the connecting shaft 410. The output end of the first driving cylinder 220 is hinged to the first transmission block 211. The first bearing 212 is supported between the connecting shaft 410 and the first transmission block 211. The first follower 213 is a cam bearing follower. There are two first followers 213, which are arranged on different push-up ends of the first transmission block 211. The first follower 213 is suitable for pushing the first clamping assembly 110 and the second clamping assembly 120 to move in reverse under the drive of the first transmission block 211. By using the first follower 213 to push the first clamping assembly 110 and the second clamping assembly 120, rolling friction occurs between the first transmission assembly 210 and the clamping mechanism 100, and the transmission is smoother and more labor-saving.

[0047] In this embodiment, the first transmission block 211 includes a transmission part 2111 and a connection part 2112 connected to the transmission part 2111. The transmission part 2111 is in a long strip structure, and the length direction is perpendicular to the axial direction of the connecting shaft 410. The push-up ends are located at both ends of the transmission part 2111 in the length direction. A mounting hole 2113 is provided through the middle of the transmission part 2111. The outer ring of the first bearing 212 is interference fit with the inner wall of the mounting hole 2113, and the inner ring of the first bearing 212 is interference fit with the connecting shaft 410. The connection part 2112 is connected to the side of the transmission part 2111 in the width direction and extends along the radial direction of the connecting shaft 410. The output end of the first driving cylinder 220 is hinged to the end of the connection part 2112 away from the transmission part 2111.

[0048] Preferably, a flange 2114 is provided around the inner wall of the mounting hole 2113, the lower side of the outer ring of the first bearing 212 is supported on the flange 2114, a limiting bolt 214 is threadedly connected to the transmission part 2111, and the cap of the limiting bolt 214 is suitable for abutting against the lower side of the outer ring of the first bearing 212, thereby improving the axial installation reliability of the first bearing 212.

[0049] When the first follower 213 pushes the first clamping assembly 110 and the second clamping assembly 120, the pulling force applied by the first drive cylinder 220 is F1, the thrust applied by the first follower 213 is F2, the perpendicular distance from the rotation center of the first transmission block 211 to the line of action of the pulling force F1 is L1, and the perpendicular distance from the rotation center of the first transmission block 211 to the line of action of the thrust F2 is L2, L1 is greater than L2, and since F1*L1=F2*L2, F1 is smaller than F2, so after adopting the first transmission block 211 of the above structure, it is more labor-saving for the first drive cylinder 220 to push the first clamping assembly 110 and the second clamping assembly 120, the thrust requirement for the first drive cylinder 220 is low, and the adaptability is better. The line of action of the pulling force F1 is specifically the axis of the first driving cylinder 220, and the line of action of the thrust F2 is specifically the line between the contact point where one of the first followers 213 contacts the first clamping assembly 110 and the center of the first follower 213, or the line between the contact point where the other first follower 213 contacts the second clamping assembly 120 and the center of the first follower 213.

[0050] Further, the second transmission assembly 310 includes a second transmission block 311, a second bearing 312, and a second follower 313. The second transmission block 311 is sleeved outside the connecting shaft 410 and has two opposite push-against ends in the radial direction of the connecting shaft 410. The output end of the second driving cylinder 320 is hinged to the second transmission block 311. The second bearing 312 is supported between the connecting shaft 410 and the second transmission block 311. The structure of the second follower 313 is the same as that of the first follower 213. The number of the second followers 313 is also two, and they are separately arranged on different push-against ends of the second transmission block 311. The second follower 313 is suitable for pushing the first clamping assembly 110 and the second clamping assembly 120 to move in reverse under the drive of the second transmission block 311.

[0051] The structure of the second transmission block 311 is the same as or similar to that of the first transmission block 211, and the present invention will not be repeated here. A limiting bolt 214 is also provided on the second transmission block 311 to axially limit the second bearing 312. When the second follower 313 pushes the first clamping assembly 110 and the second clamping assembly 120, the pulling force applied by the second drive cylinder 320 is F3, and the thrust applied by the second follower 313 is F4. The vertical distance from the rotation center of the second transmission block 311 to the line of action of the pulling force F3 is L3, and the vertical distance from the rotation center of the second transmission block 311 to the line of action of the thrust F4 is L4. L3 is greater than L4. Since F3*L3=F4*L4, F3 is less than F4, so that after adopting the second transmission block 311 of the above structure, it is more labor-saving for the second drive cylinder 320 to push the first clamping assembly 110 and the second clamping assembly 120.

[0052] Further, refer to Figure 5 and Figure 6As shown, the first clamping assembly 110 includes a first sliding frame 111 and a first clamping member 112.

The mounting seat 400 is provided with a slide rail assembly 130 on one side of the second horizontal direction. The slide rail assembly 130 includes a slide rail 131 arranged along the first horizontal direction and a first slider 132 and a second slider 133 slidably connected to the slide rail 131. The first sliding frame 111 is fixed to the first slider 132, and the second sliding frame 121 is fixed to the second slider 133. After the first clamping member 112 and the second clamping member 122 are installed, the first clamping member 112 and the second clamping member 122 are located at one side of the mounting base 400 in the second horizontal direction to prevent the mounting base 400 from obstructing the first clamping member 112 and the second clamping member 122 in the vertical direction.

[0053] The first sliding frame 111 and the second sliding frame 121 both extend along the second horizontal direction toward the other side of the mounting seat 400. The first sliding frame 111 is provided with a first matching block 1111 at the extended end, and the second sliding frame 121 is provided with a second matching block 1211 at the extended end. The first transmission assembly 210 and the second transmission assembly 310 are located at the first matching block 1111 and the second matching block 1211 to cooperate with the first matching block 1111 and the second matching block 1211. There are multiple first clamping members 112 and the second clamping member 122, and they are arranged at intervals along the first horizontal direction. The first clamping member 112 and the second clamping member 122 correspond to each other one by one to cooperate to form multiple clamping units, and each clamping unit can clamp a welding strip. When the first matching block 1111 and the second matching block 1211 move toward each other, the multiple clamping units are synchronously switched to a closed state, and when the first matching block 1111 and the second matching block 1211 move away from each other, the multiple clamping units are synchronously switched to an open state.

[0054] Specifically, the first sliding frame 111 includes a first frame body 1112 and a first connecting plate 1113. The first frame body 1112 is located on one side of the mounting seat 400 in the second horizontal direction. One side of the first connecting plate 1113 is fixed to the first frame body 1112 and the first sliding block 132 respectively, and the other side extends along the second horizontal direction to the other side of the mounting seat 400 in the second horizontal direction.

The first connecting plate 1113 is located above the second driving cylinder 320, and the first matching block 1111 and the second driving cylinder 320 are located on the same side and suspended from the mounting seat 400.

[0055] The first frame 1112 is in a long block structure, and the length direction is parallel to the first horizontal direction.

A plurality of mounting grooves 1114 are arranged at intervals along the first horizontal direction. The first clamping member 112 corresponds to the mounting grooves 1114 one by one to be respectively received in different mounting grooves 1114. The first clamping member 112 is rotatably connected to the first frame 1112, and its rotation axis is parallel to the second horizontal direction. The mounting groove 1114 extends to the bottom side of the first frame 1112 along the vertical direction, and the lower end of the first clamping member 112 extends from the bottom side of the first frame 1112 from the mounting groove 1114. A second elastic member 113 is connected between the upper end of the first clamping member 112 and the side wall of the mounting groove 1114. The second elastic member 113 is a spring, and the expansion and contraction direction is parallel to the first horizontal direction.

[0057] Further, the second sliding frame 121 includes a second frame body 1212 and a second connecting plate 1213. The second frame body 1212 is located on one side of the mounting seat 400 in the second horizontal direction. One side of the second connecting plate 1213 is respectively fixed to the second frame body 1212 and the second slider 133, and the other side extends along the second horizontal direction to the other side of the mounting seat 400 in the second horizontal direction. There is at least one second slider 133, and it is located between the first sliders 132.

The second connecting plate 1213 is located above the first driving cylinder 220. The second matching block 1211 and the first driving cylinder 220 are located on the same side and are suspended from the mounting seat 400.

By adopting the above structure, the first sliding frame 111 and the second sliding frame 121 can be made more compact without affecting the sliding of the first sliding frame 111 and the second sliding frame 121.

[0059] The second frame 1212 is also in a long block structure, and the length direction is parallel to the first horizontal direction, and the two ends of the second frame 1212 extend to the two ends of the first frame 1112.

[0060] The second clamping member 122 is disposed on a side of the second frame 1212 facing the first frame 1112, and extends downward from the bottom side of the second frame 1212. The first frame 1112 is provided with an escape portion 1116 extending through it along the second horizontal direction, and the escape portion 1116 corresponds to the second clamping member 122 one by one to escape the second clamping member 122, and the adjacent second clamping members 122 and the first clamping member 112 are arranged opposite to each other in the first horizontal direction.

[0061] The working process of the welding ribbon clamping device of the present invention is as follows: initially, the first driving cylinder 220 and the second driving cylinder 320 are both in a retracted state, and the first matching block 1111 and the second matching block 1211 are abutted against the first follower 213 at both ends of the first transmission block 211 under the action of the first elastic member, and the clamping unit is in a fully open state; when the assembly process is required, the welding ribbon flows to different clamping units one by one, and the first driving cylinder 220 and the second driving cylinder 320 switch from the retracted state to the extended state. During this process, the first transmission block 211 rotates clockwise, and the second transmission block 311 rotates counterclockwise to release the obstruction of the first matching block 1111 and the second matching block 1211. The first matching block 1111 and the second matching block 1211 are moved along the first horizontal direction under the rebound action of the first elastic member. The two second followers 313 respectively turn to the first matching block 1111 and the second matching block 1211 to push the two to move backwards, so that the clamping unit is in a slightly open state, so as to loosen the welding strip and achieve the purpose of guiding and limiting when the welding strip is pulled out; after the welding strip is pulled out, the first driving cylinder 220 switches from the extended state to the retracted state, during which the first transmission block 211 rotates counterclockwise, and the two first followers 213 respectively turn to the first matching block 1111 and the second matching block 1211 to push the two to continue to move backwards, so that the clamping unit is in a fully open state, so as to continue to receive the welding strip.

[0062] In addition, refer to Figure 7 As shown, the solder strip clamping device further comprises a lifting mechanism 500, which is in transmission connection with the mounting seat 400 to drive the mounting seat 400 to lift and lower in the vertical direction. In addition, the present invention further provides a stringing machine, comprising the aforementioned solder strip clamping device.
