Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic cell assembly string welding processing equipment, and in particular to a device for taking and placing a batch of welding strips and a system thereof. Background Art

[0002] When making battery modules in the photovoltaic field, multiple battery cells need to be connected by welding tapes. Since the number of battery cells to be laid out is large, the number of welding tapes required is also large. In addition, since the welding tapes connecting the battery cells are in sections, the welding tapes need to be cut and then moved to the battery cells. In the existing welding tape layout machines, some use suction cups for pick-up and placement. The suction cups have multiple microholes, which can simultaneously absorb multiple welding tapes on a battery cell. If multiple welding tapes on multiple battery cells are simultaneously absorbed, the bending state of the welding tapes, the flatness of the suction cups and the welding tape trays will affect the success rate of absorption, and the welding tapes are not fixed, and the position accuracy of the welding tapes cannot be guaranteed; when placing the welding tapes, the bending state of the welding tapes and the parallelism between the battery cell and the suction cup will also affect the position accuracy when placing the welding tapes. Therefore, the current welding tape placement mechanism uses a clamping mechanism to drive the welding tape, but the existing clamping mechanism requires multiple sets of power, resulting in complex mechanisms, complex gas circuits and circuits, and inconvenient maintenance.

[0003] In addition, when the solder strip is conventionally clamped and transported, no pre-positioning is performed before placing the solder strip, which causes the solder strip to easily shift when clamped and affects the position accuracy of the solder strip. Utility Model Content

[0038] The present application provides a device 100 for placing and taking a batch of solder strips. Figures 1 to 4The device 100 for placing and taking a batch of solder strips comprises a plurality of clamping devices 10 and a first driving mechanism 20, wherein each clamping device 10 comprises a plurality of clamping jaw units arranged side by side, each clamping jaw unit comprises two clamping jaws 120 arranged colinearly and separately along a first direction A, the first direction A is the extending direction of the solder strip, one clamping jaw unit is used to clamp a solder strip, and the clamping jaw 120 comprises a fixed clamping jaw 121 and a movable clamping jaw 122 arranged opposite to each other; wherein the plurality of clamping jaw units are arranged side by side along a second direction B, the second direction B is perpendicular to the first direction A, and the plurality of clamping devices 10 are arranged side by side along the first direction A or the second direction B. The first driving mechanism 20 includes a first power member 22, which can be a cylinder, a motor or an electric cylinder, etc., a first series driving member 24 connected to the first power member 22, and a plurality of driving modules 26, wherein the first power member 22 is used to drive the first series driving member 24 to move, and the first series driving member 24 is used to simultaneously drive all driving modules 26 to move; the number of driving modules 26 is the same as the number of clamping devices 10 and the positions are arranged in a one-to-one correspondence, and one driving module 26 is used to simultaneously drive all the moving jaws 122 in a clamping device 10 to move, and the driving module 26, under the drive of the first series driving member 24, drives all the moving jaws 122 in the corresponding clamping device 10 to open and close relative to the fixed jaw 121.

[0039] In the solder strip batch picking and placing device 100 provided in the present application, the multiple clamping devices 10 can be arranged side by side along the first direction A or the second direction B to achieve flexible arrangement of the clamping devices 10, so that it can be suitable for a variety of scenarios; each clamping device 10 includes a plurality of clamping units, and each clamping unit can be used to clamp a corresponding solder strip, so the solder strip batch picking and placing device 100 can clamp solder strips in batches and has the ability to clamp a large number of solder strips at the same time.

[0040] The number of the clamping devices 10 may be 2, 3, 4, 5, 6, 8, 10 or more, and the number of the clamping units on each clamping device 10 may be 2, 3, 4, 5, 6, 8, 10, 12, 16 or more. For example, if the number of the clamping devices 10 is 7, the number of the clamping units on each clamping device 10 is 6, and the 7 clamping devices 10 are arranged along the first direction A, it can be known that the solder strip batch pick-up and placement device 100 can clamp 42 solder strips at the same time, and the 42 solder strips are arranged in 6 rows and 7 columns; if the 7 clamping devices 10 are arranged along the second direction B, the 42 solder strips are arranged in rows along the second direction B, and are substantially parallel to each other.

[0041] Each clamping jaw unit includes two clamping jaws 120 arranged colinearly and separately along a first direction A, and the two clamping jaws 120 cooperate with each other to clamp a welding strip; the fixed clamping jaw 121 in the clamping jaws 120 is relatively fixed, while the movable clamping jaw 122 moves and cooperates with the fixed clamping jaw 121 to clamp the welding strip. Optionally, the movable clamping jaw 122 is hinged with the fixed clamping jaw 121, that is, the movable clamping jaw 122 swings back and forth relative to the fixed clamping jaw 121 to clamp or release the welding strip; or, the fixed clamping jaw 121 is relatively arranged on a fixed base, and the movable clamping jaw 122 is connected to a movable part that can move relative to the base, and the movable part cooperates with the fixed clamping jaw 121 by reciprocating along a direction, thereby clamping or releasing the welding strip; in addition, the movable clamping jaw 122 and the fixed clamping jaw 121 may also have other movement modes, which are not listed one by one in this application.

[0042] As an example, Figure 1 As shown, a plurality of clamping devices 10 are arranged side by side along a first direction A, and a first serial driving member 24 spans across all the clamping devices 10 along the first direction A (that is, the length of the first serial driving member 24 covers the length of all the clamping devices 10). The first power member 22 can simultaneously drive the plurality of clamping devices 10 to move through the first serial driving member 24 and a plurality of driving modules 26, and specifically, simultaneously drive all the clamping jaws 120 to move. The number of the first power member 22 is one, which is arranged on one end side of the plurality of clamping devices 10 arranged side by side or above the plurality of clamping devices 10. The space for clamping the welding ribbon is below the device 100 for batch picking and placing the welding ribbon, so the power arrangement in the present application is simple, and the first serial driving member 24 drives the plurality of driving modules 26 and then drives all the clamping devices 10, thereby saving the cost of the power device.

[0043] Among them, there are many ways for the first serial driving member 24 to drive all the driving modules 26 to move at the same time. Optionally, the first power member 22 can drive the plurality of driving modules 26 to move at the same time by driving the pusher in the first serial driving member 24 to rotate and swing (see the examples below for details) to achieve simultaneous driving of multiple dynamic clamps 122; or, the first power member 22 can drive the plurality of driving modules 26 to move up and down by driving the first serial driving member 24 to move up and down, so as to achieve simultaneous driving of multiple dynamic clamps 122; or, the first serial driving member 24 can drive the plurality of driving modules 26 to move at the same time by reciprocating in the horizontal direction, so as to achieve simultaneous driving of multiple dynamic clamps 122 (see the examples below for details). It should be noted that the specific structure of the first serial driving member 24 is not particularly limited here, as long as the first power member 22 can drive the first serial driving member 24 to move, and the first serial driving member 24 includes a structural member that can simultaneously drive the driving modules 26 of each clamping device 10 to move.

[0044] The present application limits the first driving mechanism 20 to simultaneously drive the opening and closing movements of the jaws 120 on each clamping device 10, so that each jaw unit can clamp or release the welding strip at the same time, that is, one set of power can drive all the jaws 120 on the welding strip batch picking and placing device 100. Relatively speaking, the number of power sets required for the welding strip batch picking and placing device 100 provided by the present application is greatly reduced, thereby reducing the complexity and cost of the mechanism and being more conducive to maintenance; and multiple clamping devices 10 can also be flexibly arranged to adapt to different scenarios. Each clamping device 10 also includes multiple jaw units, each jaw unit can be used to clamp a corresponding welding strip, so the welding strip batch picking and placing device 100 can clamp welding strips in batches and has the ability to clamp a large number of welding strips at the same time.

[0045] See also Figure 2 , Figure 4 and Figure 5 , wherein the driving module 26 includes two jaw plates 260 separately arranged along the first direction A, each jaw plate 260 includes a plurality of driving teeth 262 arranged along the second direction B, one driving tooth 262 corresponds to driving one or two jaws 120, and the power provided by the first series driving member 24 drives the driving tooth 262, thereby pushing the dynamic jaw 122 corresponding to the driving tooth 262 to move.

[0046] The clamping jaws 120 in the clamping device 10 are arranged in two rows spaced apart along the first direction A, and each row of the clamping jaws 120 includes a plurality of clamping jaws 120 spaced apart along the second direction B, and one clamping jaw insert plate 260 drives one row of the clamping jaws 120 accordingly. Optionally, in the same row of the clamping jaws 120, the clamping jaws 120 are distributed in the same posture, for example, the movable clamping jaws 122 in the same clamping jaw 120 are all located on the left side of the fixed clamping jaw 121, or the movable clamping jaws 122 in the same clamping jaw 120 are all located on the right side of the fixed clamping jaw 121, then one driving tooth 262 can drive one movable clamping jaw 122 accordingly. Optionally, in the same row of jaws 120, two adjacent jaws 120 are distributed in different postures. For example, in two adjacent jaws 120, the dynamic jaw 122 in one jaw 120 is located on the left side of its fixed jaw 121, and the dynamic jaw 122 in the other jaw 120 is located on the right side of its fixed jaw 121, and the two dynamic jaws 122 are adjacent (there is no fixed jaw 121 between the two dynamic jaws 122), then one driving tooth 262 can correspondingly drive the two adjacent dynamic jaws 122.

[0047] Specifically, the first serial driving member 24 can drive the two jaw plates 260 to perform lifting motion, thereby driving the corresponding movable jaw 122 to move; or, the first serial driving member 24 can drive the two jaw plates 260 to reciprocate along the second direction B, thereby driving the corresponding movable jaw 122 to move; wherein, the movable jaw 122 can specifically perform a swinging motion.

[0048] By providing two clamping jaws inserting plates 260, all the clamping jaws 120 on a clamping device 10 can be driven to move, that is, a batch drive of all the clamping jaws 120 in a clamping device 10 can be realized through a simple structural arrangement, achieving high efficiency and greatly saving power arrangement costs. In addition, all the clamping jaws in a clamping device 10 pick up and place the welding strip together, providing consistency in the movement of the clamping jaws 120.

[0049] Combined with reference Figure 5 In this embodiment, the movable jaw 122 is hinged to the fixed jaw 121, and the first serial driving member 24 drives the driving tooth 262 to move up and down (i.e., lifting and lowering movement). The driving tooth 262 is arranged on the side of the movable jaw 122, and one end of the movable jaw 122 that does not clamp the welding strip is provided with a first plane 101 and a first curved surface 102 that are connected. The side of the driving tooth 262 close to the movable jaw 122 is provided with a second plane 202 and a third plane 203 that are connected. The second plane 202 is inclined relative to the third plane 203, and the second plane 202 is used to abut the first curved surface 102, thereby driving the movable jaw 122 to swing, and the third plane 203 is used to fit with the first plane 101, thereby controlling the opening angle of the movable jaw 122 relative to the fixed jaw 121, so that each jaw 12 can maintain the same opening angle when opening, thereby improving the movement consistency of each jaw 12.

[0050] Furthermore, after the third plane 203 is in contact with the first plane 101, the driving tooth 262 can continue to move downward, and the opening angle of the clamping jaw 12 will remain unchanged, that is, a certain movement margin is reserved between the third plane 203 and the first plane 101, which can avoid the driving tooth 262 from colliding with the dynamic clamping jaw 122.

[0051] Continue reading Figure 4 The driving module 26 also includes a base 14 and a first guide member 265. The first guide member 265 is slidably connected to the base 14 along the vertical direction C. The clamping claw plate 260 is connected to the first guide member 265. The first serial driving member 22 drives the first guide member 265 to move, thereby driving the driving tooth 262 to move up and down in the vertical direction C.

[0052] The base 14 and the first guide member 265 can be guided by the shaft hole; or the base 14 is provided with a slide groove or a slide rail, and the first guide member 265 is provided with a slider structure, so as to slide with the slide groove or the slide rail on the base 14. The clamping claw plate 260 can be connected to one side of the first guide member 265 and move with the first guide member 265. The first serial driving member 24 drives the first guide member 265 to move, thereby stably and reliably driving the clamping claw plate 260 to move.

[0053] By means of the sliding limitation between the first guide member 265 and the base 14 in the vertical direction C, and the connection of the clamping jaw plate 260 to the first guide member 265, it is possible to ensure that the clamping jaw plate 260 can perform lifting and lowering movements in the vertical direction C with high precision and high stability, thereby improving the driving reliability and stability of the driving tooth 262 on the movable clamping jaw 122.

[0054] Furthermore, if Figure 3 As shown, the first guide member 265 includes two first linear bearings 266 arranged along the vertical direction C on the base 14, two first guide rods 267 respectively arranged in the first linear bearings 266, and a first pressure plate 268 connected to the top of the first guide rod 267; the clamping claw plate 260 is connected to the first pressure plate 268, and the first series driving member 24 drives the first pressure plate 268 in the first guide member 265 to move, thereby driving the driving tooth 262 to perform lifting and lowering movements in the vertical direction C.

[0055] When the first linear bearing 266 is assembled with the first guide rod 267, each first guide rod 267 moves more smoothly and has a higher movement accuracy, so that the first pressure plate 268 drives the clamping claw plate 260 to move with high efficiency and high accuracy. The first pressure plate 268 can be a flat plate. Furthermore, when the first serial driving member 24 includes the first driving rod 240 and the first pushing member 242 as described below, the first pushing member 242 slides in contact with the surface of the first pressure plate 268 by swinging; or when a plurality of clamping devices 10 are arranged side by side along the second direction B, the first pressure plate 268 includes a flat plate and a guide boss arranged on the flat plate, and the guide boss can have an inclined plane or an arc surface. The first pushing member 242 slides in contact with the inclined plane or the arc surface of the guide boss by swinging or moving, thereby driving the first pressure plate 268 to perform lifting and lowering motion under the limitation of the first guide member 265.

[0056] Furthermore, a first elastic member 269 is provided between the first pressing plate 268 and the base 14. When the first pressing plate 268 moves downward, the first elastic member 269 is also compressed. After the force applied to the first pressing plate 268 is reduced or removed, the elastic force provided by the first elastic member 269 will drive the first pressing plate 268 to rise, thereby driving the clamping claw plate 260 to rise; wherein a plurality of first elastic members 269 are provided between the first pressing plate 268 and the base 14, and the plurality of first elastic members 269 together form a multi-point elastic support between the first pressing plate 268 and the base 14, thereby providing a more stable support to the first pressing plate 268, so that the first pressing plate 268 can rise smoothly. The first elastic member 269 can be an elastic structure such as a compression spring or an elastic sleeve. Of course, in order to make the clamping claw plate 260 rise, other forms can also be adopted as long as the corresponding functions can be achieved.

[0057] In this embodiment, Figure 2 , Figure 3As shown, the first serial driving member 24 includes a first driving rod 240 and at least one first pushing member 242 connected to the first driving rod 240. The first pushing member 242 is in sliding contact with the clamping claw plate 260. The first driving rod 240 slides with the first pushing member 240 on the clamping claw plate 260, thereby driving the driving tooth 262 to move.

[0058] The first driving rod 240 connects all the clamping devices 10 in series along the first direction A or the second direction B.
