Weld and take closing device and stringer

Technical Field

The utility model relates to the field of photovoltaic technology, especially, relate to a weld and take closing device and stringer.

Background

In the manufacturing process of the photovoltaic module, a plurality of battery pieces can be connected by using a welding strip. These solder strips may be rectangular in cross-section, circular in cross-section, triangular in cross-section, etc.

In the process of welding the welding strip on the battery piece, the welding strip can be compressed by the welding strip compressing device, so that the welding strip is in close contact with the battery piece, and the problems of insufficient soldering, partial soldering and the like are avoided. For example, a weld bead pressing device having a cylindrical ram may be used to press a weld bead of rectangular cross-section. However, when various welding strips with different shapes are used, the pressure head of the welding strip pressing device is often required to be replaced for many times, and the working efficiency is low.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a weld and take closing device and stringer to the better compresses tightly welds the area, and improves the work efficiency when compressing tightly different shapes and welding the area.

In a first aspect, the utility model provides a weld and take closing device. The solder strip pressing device comprises a support frame, at least one pressing piece group and at least one controllable locking mechanism. Each pressing member group includes a plurality of pressing members stacked in a first direction; at least one pressure piece group is arranged on the support frame. Each controllable locking mechanism is arranged on the support frame and is provided with an adjustable locking space. Each pressure piece set is located in a locking space provided by the corresponding controllable locking mechanism.

When the controllable locking mechanism is in the unlocking state, each pressing piece included in the corresponding pressing piece group of the controllable locking mechanism can move along a second direction, and the second direction is intersected with the first direction. When the controllable locking mechanism is in a locking state, the pressure piece group is locked by the corresponding controllable locking mechanism.

When the technical scheme is adopted, each pressing piece group included in the welding strip pressing device comprises a plurality of pressing pieces which are stacked along the first direction. And each pressure piece group is positioned in the locking space of the corresponding controllable locking mechanism, and the pressure pieces of the pressure piece group are controlled by the controllable locking mechanism to move or not move. When the welding strip pressing device presses the welding strip with a specific shape, the first direction can be consistent with the width of the welding strip, the controllable locking mechanism is controlled to be in an unlocking state, and the pressing piece can move along the second direction. When the pressing member group is pressed on the welding strip, because the pressing members of the pressing member group are arranged along the width direction of the welding strip and each pressing member is movable, the pressing members closely contacted with the surface of the welding strip can be jacked up by the welding strip (along the second direction), and the pressing members contacted with different positions on the surface of the welding strip are jacked up at different heights. At this time, each pressing piece of the pressing piece group pressed on the welding strip is surrounded into a contour shape matched with the surface shape of the welding strip. After the controllable locking mechanism is locked, each pressing piece of the pressing piece group can not move. At the moment, the pressing piece group is in close contact with the welding strip, and the positions of the pressing pieces are fixed, so that the effect of pressing and fixing the welding strip can be achieved. When the welding strips with the same shape are pressed, the pressing piece group in a locking state can be directly used for pressing. When the welding strips with different shapes are pressed, the controllable locking mechanism can be in the unlocking state again, and the welding strips are pressed as above. Based on this, the utility model discloses a weld and take closing device utilizes same pressure piece group, can realize carrying out along with the shape to the multiple strip that welds of different shapes and compress tightly fixedly. On the one hand, need not to change the pressure piece group that is used for compressing tightly, can improve work efficiency. On the other hand, the profile shape that the casting die group can contact with the solder strip according to the shape of solder strip, the casting die group for the casting die group can with solder strip surface in close contact with, thereby can be better compress tightly fixed solder strip, reduce solder strip roll, skew, rosin joint scheduling problem.

In some implementations, the support frame has at least one guide through hole along the second direction, and each press set is mounted in the corresponding guide through hole. At this time, the guide through-hole may define a moving direction of the pressing member group. When the pressing piece is jacked up by the welding strip, the pressing piece can move along the second direction defined by the guide through hole, so that the problems that the moving directions of the pressing pieces are not consistent and the moving directions of the pressing pieces are deviated can be reduced. Therefore, the arrangement of the guide through holes can reduce the deviation of the moving direction of each pressing piece and improve the reliability of the pressing piece group.

In some implementations, one end of the set of press pieces extends out of the guide through hole. When the welding strip pressing device is continuously close to the welding strip, the distance between the pressing piece group and the welding strip is smaller than the distance between the bottom surface of the support frame and the welding strip. At this time, the pressing member group is closer to the surface of the solder strip, so that the pressure member group can be ensured to be in contact with the surface of the solder strip, and the pressing member group can press the solder strip.

In some implementations, the compression element is a sheet compression element or a block compression element; the thickness of the sheet type casting die is 0.1 mm-1 mm; the width of the sheet type pressing piece is 2mm-6 mm. When the thickness of the sheet type pressing piece is in the range, the thickness of the sheet type pressing piece is small, and the precision of the laminated pressing piece group is high. When the pressing part group compresses the welding strip, the pressing parts on the unit width of the welding strip are more in number, and the contact area between the pressing part group and the welding strip is larger, so that the pressing part group can compress and fix the welding strip better. When the width of the sheet type pressing piece is in the range, the length of the welding strip in contact with the pressing piece group is 2mm-6 mm. At the moment, the length of the welding strip in contact with the pressing piece group and the contact area of the welding strip with the pressing piece group are larger, so that the pressing piece group can better compress and fix the welding strip.

In some implementations, the length of the press set in the first direction is greater than or equal to 2/3 of the solder ribbon width. The compression element set may cover 2/3 the width of the weld bead when the compression element set is compressed against the weld bead. At the moment, the pressing piece group has a large covering area, can well compress and fix the welding strip, and reduces the problems that the welding strip is easy to roll, shift and the like when the covering is small.

In some implementations, each controllable locking mechanism includes an actuating member disposed on the support bracket. The driving member is used for adjusting the locking width of the locking space. At this time, the controllable locking mechanism can be controlled to be in a locking state or an unlocking state through the driving piece, so that the pressing piece of the pressing piece group is in a movable state or an immovable state. During the locking state, the pressing part group can play the effect of compressing tightly, and during the unblock state, the pressing part group can warp with welding the outline that takes the contact, can take the shape along with welding. That is, the unlocked state allows for the change in profile shape of the press set for different shapes of weld beads of the press. Therefore, the pressing piece group can be controlled to change the contour shape or press the welding strip by controlling the driving piece. At the moment, the transformation of the outline shape of the pressing piece group can be rapidly realized, the welding strip is compressed, and the working efficiency is improved.

In some implementations, each controllable locking mechanism further includes opposing first and second locking members. First retaining member and second retaining member all can remove and establish on the support frame, and locking space is located between first retaining member and the second retaining member. The driving parts are two, one of the driving parts is connected with the first locking part, and the other driving part is connected with the second locking part. At this moment, can be through the position of controlling first retaining member and second retaining member both, and then the width in comparatively nimble control locking space.

In some implementations, each controllable locking mechanism further includes opposing first and second locking members. First retaining member is portable to be established on the support frame, and the second retaining member is fixed to be established on the support frame, and the locking space is located between first retaining member and the second retaining member. The driving member is connected with the first locking member. At the moment, the movable first locking piece and the fixedly arranged second locking piece can realize relative movement under the driving of the driving piece, so that the width of a locking space is increased or reduced, and further the controllable locking mechanism is in an unlocking state or a locking state.

In some implementations, the first retaining member snaps onto the driving member. At this moment, the connected mode of joint can realize first retaining member and being connected with dismantling of driving piece, and the first retaining member of being convenient for is installed, is dismantled with the driving piece fast, and then can improve production efficiency.

In some implementations, the first locking member is a pad, the first locking member has a slot, the driving member has a protrusion, and the slot is engaged with the protrusion. The second locking piece is of a sheet structure. At this moment, first retaining member can realize the joint through arch and draw-in groove with the driving piece, the quick dismantlement installation of being convenient for.

In some implementations, the material of the first locking member and/or the second locking member is an elastic material. When first retaining member and second retaining member contact with the pressure piece group, elastic material's first retaining member and second retaining member have better cushioning effect, can realize elastic contact, reduce the damage to the pressure piece, prolong the life of pressure piece group.

In some implementations, the drive member is a rod drive member. The rod-shaped driving piece comprises a screw rod, an electric push rod or an air cylinder push rod. The driving pieces can realize automatic control of the controllable locking mechanism.

In some implementations, when the number of controllable latching mechanisms is multiple, at least two controllable latching mechanisms share a common actuating member. At the moment, the number of driving pieces used by the welding strip pressing device can be reduced, the structure is simplified, and the cost is reduced. Also, fewer actuators facilitate simultaneous control of multiple controllable locking mechanisms.

In some implementations, when the weld bead pressing device presses the weld bead, the first direction is coincident with a width direction of the weld bead, and the second direction is perpendicular to a welding surface of the weld bead.

With the development of photovoltaic technology, photovoltaic modules gradually enter the era of large-scale mass production and high power. In order to meet the requirements of low cost and high power, the structure and the manufacturing process of the solar cell are improved. From the aspect of manufacturing process, the size of the battery piece is continuously increased to reduce the manufacturing cost. From the viewpoint of metallization structure (interconnection technology), the solder strip on the cell mostly adopts a circular solder strip or a triangular solder strip. The circular welding strip refers to a welding strip with a circular cross section. The triangular welding strip is a welding strip with a triangular cross section. The solder strip with the shape can reflect light irradiated to the solder strip area to the battery surface, so that the light utilization rate is improved, and the power of the photovoltaic module is increased.

In the metallization process, when the stringer is to weld the target position on the battery piece surface with the solder strip, can utilize and weld the target position that takes closing device to compress tightly the solder strip on the battery piece surface to reduce and weld the skew that takes the roll, can't laminate and lead to, rosin joint scheduling problem. As shown in fig. 1, a currently-used solder strip pressing device includes a support 1 and a pressing head 2. The ram 2 is mounted on the frame 1. The ram 2 is a generally cylindrical ram 2. The cylindrical pressure head 2 can conveniently compress the flat welding strip, and further achieves a better welding effect. To circular solder strip and triangle solder strip, cylindrical pressure head can't play fine effect that compresses tightly, appears skew easily, rosin joint scheduling problem. Even though the pressure heads aiming at the circular welding strip and the triangular welding strip exist in the prior art, the pressure heads still need to be replaced for many times aiming at various welding strips with different shapes, and the production efficiency is influenced.

In order to solve the technical problem, the embodiment of the utility model provides a stringer. The series welding machine comprises a welding strip pressing device. The series welding machine improves the pressure head of the welding strip pressing device for pressing the welding strip, so that the welding strip pressing device can better press various welding strips with different shapes. Moreover, when various welding strips in different shapes are faced, a pressure head does not need to be replaced, and the production efficiency can be further improved.

As shown in fig. 2 to 6, the solder strip pressing device includes a support frame 10, at least one pressing member set 20, and at least one controllable locking mechanism 30. Each of the pressing member groups 20 includes a plurality of pressing members 21 stacked along the first direction a; at least one press set 20 is mounted on the support frame 10. Each controllable locking mechanism 30 is provided on the support frame 10, each controllable locking mechanism 30 having an adjustable locking space. Each pressure piece set 20 is located in a locking space provided by a corresponding controllable locking mechanism 30. When the controllable locking mechanism 30 is in the unlocked state, each pressing member 21 included in the pressing member group 20 corresponding to the controllable locking mechanism 30 is movable in the second direction B, which intersects with the first direction a. When the controllable locking mechanism 30 is in the locking state, the pressing member set 20 is locked by the corresponding controllable locking mechanism 30.

As shown in fig. 2 to 6, when the solder strip 40 is pressed by the solder strip pressing device, the first direction a is the same as the width direction of the solder strip 40, and the second direction B is perpendicular to the soldering surface of the solder strip 40.

In practice, the support frame 10 with the pressing member set 20 is continuously close to the solder strip 40. When the pressing member set 20 contacts the welding strip 40, the controllable locking mechanism 30 is controlled to be in an unlocking state, so that the pressing member 21 of the pressing member set 20 can move. After the pressing member 21 of the pressing member set 20 is tightly contacted with the surface of the welding strip 40, the controllable locking mechanism 30 is controlled to be in a locking state, and the pressing member set 20 presses the welding strip.

As is apparent from the above-described structure of the solder ribbon hold-down device, each of the pressing member groups 20 included in the solder ribbon hold-down device includes a plurality of pressing members 21 stacked in the first direction a. And, each presser group 20 is located in the locking space of the corresponding controllable locking mechanism 30, and the presser 21 of the presser group 20 is controlled to be movable or immovable by the controllable locking mechanism 30. When the welding strip pressing device presses the welding strip 40 with a specific shape, the first direction can be consistent with the width of the welding strip 40, the controllable locking mechanism 30 is controlled to be in an unlocking state, and the pressing piece 21 can move along the second direction B. When the pressing member group 20 is pressed against the solder ribbon 40, since the pressing members 21 of the pressing member group 20 are arranged in the width direction of the solder ribbon 40 and each pressing member is movable, the pressing members 21 in close contact with the surface of the solder ribbon 40 can be pushed up (in the second direction) by the solder ribbon 40, and the pressing members 21 in contact with different positions on the surface of the solder ribbon 40 are pushed up at different heights. At this time, the pressing pieces 21 of the pressing piece group 20 pressed against the solder ribbon 40 enclose a contour shape matching the surface shape of the solder ribbon 40. After the controllable locking mechanism 30 is locked, each pressing member 21 of the pressing member set 20 is not movable. At this time, the pressing member set 20 is in close contact with the solder strip 40, and the positions of the pressing members 21 are fixed, so as to play a role of pressing and fixing the solder strip 40. When the welding strip 40 with the same shape is pressed, the pressing piece group 20 in the locking state can be directly used for pressing. When a differently shaped solder ribbon 40 is compressed, the controllable locking mechanism 30 can be re-unlocked and compressed as described above. Based on this, the utility model discloses weld and take closing device utilizes same pressure piece group 20, can realize carrying out the shape following to the multiple weld of different shapes and take 40 to compress tightly fixedly. On the one hand, the pressing member group 20 for pressing does not need to be replaced, and the working efficiency can be improved. On the other hand, the pressing member group 20 can change the contact contour shape of the pressing member group 20 and the solder strip 40 according to the shape of the solder strip 40, so that the pressing member group 20 can be in close contact with the surface of the solder strip 40, the solder strip 40 can be well pressed and fixed, and the problems of rolling, deviation, cold joint and the like of the solder strip 40 are reduced.

As shown in fig. 2 and 3, the support stand 10 mainly functions to support the pressure member set 20 and the controllable locking mechanism 30, and allows the two to move relative to the support stand 10. The support frame 10 may be a frame structure, a solid structure, or a support frame 10 formed by splicing a plurality of support plates, and is not limited thereto. Illustratively, as shown in fig. 2 and 3, the support frame 10 includes a first support plate 11, a second support plate 12, and two side plates 13 connecting the first support plate 11 and the second support plate 12, wherein the first support plate 11 and the second support plate 12 are parallel. When the first and second support plates 11 and 12 are different in length, the two side plates 13 may be bent side plates 13.

As shown in fig. 2 and 3, the above-described support frame 10 has at least one guide through-hole 14 along the second direction B, and each of the presser group 20 is fitted in the corresponding guide through-hole 14. Illustratively, when the supporting frame 10 is formed by splicing a plurality of supporting plates, a first through hole is formed in the first supporting plate 11, and a second through hole is formed in the second supporting plate 12. The first through holes and the second through holes are arranged along the second direction B to constitute the guide through holes 14. The pressing member set 20 passes through the guide through hole 14 of the support frame 10. The presser group 20 is movable in the opening direction (second direction) of the guide through hole 14 in the guide through hole 14. The guide through-hole 14 may define a moving direction of the pressing piece 21 of the pressing piece group 20. When the pressing member 21 is lifted by the solder ribbon 40, the pressing member 21 can move along the second direction defined by the guide through hole 14, so that the problems of non-uniform moving direction of the pressing members 21 and deviation of the moving direction of the pressing members 21 can be reduced. Accordingly, the guide through holes 14 can reduce the deviation of the moving direction of each pressing member 21, and improve the reliability of the pressing member group 20.

As shown in fig. 2 and 3, the shape of the guide through hole 14 matches the shape of the pressing member group 20. The size of the guide through hole 14 is only required to allow the press member group 20 to pass through, and the embodiment of the present invention is not particularly limited to this. The number of the guide through holes 14 is the same as that of the pressing member groups 20. When the press set 20 is one, the guide through hole 14 is one. When there are a plurality of the pressing member sets 20, the corresponding positions of the support frame 10 have a plurality of guiding through holes 14. The press pieces 20 are mounted in the guide through holes 14 in a one-to-one correspondence.

As shown in fig. 2 and 3, when the pressing member group 20 is mounted to the guide through hole 14, one end of the pressing member group 20 may protrude out of the guide through hole 14. When the welding strip pressing device is close to the welding strip 40, the distance between the pressing member group 20 and the welding strip 40 is smaller than the distance between the bottom surface of the support frame 10 and the welding strip 40. At this time, the pressing member group 20 is closer to the surface of the solder ribbon 40, so that it is ensured that the pressing member group 20 can be in surface contact with the solder ribbon 40, and the pressing member group 20 can press the solder ribbon 40.

As shown in fig. 2 to 4, the pressing member group 20 includes a plurality of pressing members 21 stacked in a first direction. The pressing member 21 may be a sheet pressing member 21 or a block pressing member 21. It should be understood that the compression member set 20 may include a stack of one row of compression members 21 and may also include a stack of multiple rows of compression members 21. In the plural rows of pressing members 21, each row of pressing members 21 is laminated in the first direction a.

The thickness of the sheet pressing member 21 may be 0.1mm to 1 mm. The thickness refers to a dimension of the sheet presser 21 along the stacking direction of the sheet presser 21, that is, the first direction a. Illustratively, the sheet press 21 may have a thickness of 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, or the like. When the thickness of the sheet pressing member 21 is within this range, the thickness of the sheet pressing member 21 is small, and the pressing member group 20 after lamination has high accuracy. When the pressing member set 20 presses the welding strip 40, the number of the pressing members 21 per unit width of the welding strip 40 is larger, and the contact area between the pressing member set 20 and the welding strip 40 is larger, so that the pressing member set 20 can better press and fix the welding strip 40.

The width of the sheet pressing member 21 may be 2mm to 6 mm. The width is a dimension of the sheet presser 21 in the extending direction of the solder ribbon 40, perpendicular to the first direction a and the second direction B, that is, when the solder ribbon 40 is pressed. Illustratively, the sheet presser 21 may have a width of 2mm, 2.5mm, 3mm, 3.4mm, 4mm, 5mm, 5.6mm, 6mm, or the like. When the width of the sheet pressing member 21 is within this range, the length of the solder strip 40 in contact with the pressing member group 20 is 2mm to 6 mm. At this time, the length of the solder strip 40 contacting the pressing member set 20 and the contact area with the pressing member set 20 are large, so that the pressing member set 20 can press and fix the solder strip 40 well.

The height of the sheet pressing member 21 may be 40mm to 60 mm. The height is the length of the sheet presser 21 in the second direction B. The height of the sheet pressing member 21 may be set according to the height of the supporting frame 10 as long as it is flush with the guide through hole 14 or protrudes out of the guide through hole 14.

The pressing member 21 may be made of a hard material such as metal or wood.

In the first direction, the length of the set of pressing members 20 may be greater than or equal to 2/3 of the width of the solder ribbon 40. For example, the length of the compression element set 20 may be 2/3, 0.7, 0.8, 1, 1.2, 1.3 times the width of the weld ribbon 40. When the compression member set 20 is pressed against the weld bead 40, the compression member set 20 may cover 2/3 of the width of the weld bead 40. In this case, the pressing member set 20 has a large covering area, and can press and fix the solder strip 40 well, thereby reducing problems such as easy rolling and shifting of the solder strip 40 when the covering is small. The height of the pressing member group 20 is the height of the pressing member 21. The width of the pressing member group 20 is the width of the pressing member 21, or the sum of the widths of the rows of pressing members 21.

The number of the pressing member groups 20 of the solder strip pressing device can be designed according to the number of solder strips 40 of the pressing member 21 required by the series welding machine. For example, when welding the welding tapes 40 on the surface of the 9-primary-grid (9BB) cell piece, the number of the pressing member groups 20 is 9.

As shown in fig. 2 and 3, the number of controllable locking mechanisms 30 corresponds to the number of compression members 20. The controllable locking mechanisms 30 correspond to the pressing member groups 20 one by one. Each controllable locking mechanism 30 includes opposing first 31 and second 32 locking members, and an actuating member 33. The first locking member 31 may be a block. The first locking member 31 may be a circular block or a square block, but is not limited thereto. The second locking member 32 may be a plate-like structure. The material of the first securing member 31 may be an elastic material. The material of the second locking member 32 can also be a resilient material. When the first locking member 31 and the second locking member 32 contact with the pressing member group 20, the first locking member 31 and the second locking member 32 made of elastic materials have a good buffering effect, elastic contact is achieved, damage to the pressing member 21 is reduced, and the service life of the pressing member group 20 is prolonged.

As shown in fig. 2 and 3, the first locking member 31 is movably disposed on the support frame 10, and the second locking member 32 is fixedly disposed on the support frame 10. The locking space is located between the first locking member 31 and the second locking member 32, that is, the pressing member set 20 is located between the first locking member 31 and the second locking member 32. Of course, the first locking member 31 and the second locking member 32 may be movably disposed on the supporting frame 10.

As shown in fig. 2 and 3, the driving member 33 is provided on the support frame 10 for adjusting a locking width of the locking space. When only the first locking member 31 is movably arranged, the driving member 33 is connected with the first locking member 31. At this time, under the driving of the driving member 33, the movable first locking member 31 and the fixedly disposed second locking member 32 can perform relative movement, so that the width of the locking space is increased or decreased, and the controllable locking mechanism 30 is in the unlocking state or the locking state. When both the first locking member 31 and the second locking member 32 are movably disposed, there are two driving members 33, one of the driving members 33 is connected to the first locking member 31, and the other driving member 33 is connected to the second locking member 32. At this time, the width of the locking space can be more flexibly controlled by controlling the positions of the first locking member 31 and the second locking member 32.

In practical applications, the controllable locking mechanism 30 can be controlled to be in a locking state or an unlocking state by the driving member 33, so that the pressing member 21 of the pressing member set 20 is in a movable state or in a non-movable state. In the locking state, the pressing member set 20 can play a role in pressing, and in the unlocking state, the contact profile of the pressing member set 20 and the welding strip 40 can deform along with the shape of the welding strip 40. That is, in the unlocked state, the profile shape of the presser group 20 can be changed for the differently shaped solder ribbon 40 of the presser 21. It follows that by controlling the drive 33, the set of pressure elements 20 can be controlled to change the contour or to press the weld bead 40. At this time, the change of the outline shape of the pressing member group 20 can be rapidly realized, and the welding strip 40 can be pressed, so that the working efficiency is improved.

As shown in fig. 2 and 3, when the first locking member 31 is movably disposed and the second locking member 32 is fixedly disposed, the first locking member 31 can be snapped onto the driving member 33. At this moment, the connected mode of joint can realize first retaining member 31 and driving piece 33 dismantling and be connected, and the first retaining member 31 of being convenient for is installed fast with driving piece 33, is dismantled, and then can improve production efficiency.

As shown in fig. 5, the first locking member 31 and the driving member 33 can be clamped by: the first locking member 31 has a locking slot 311, the driving member 33 has a protrusion 331, and the locking slot 311 is locked with the protrusion 331. At this time, the first locking member 31 and the driving member 33 can be clamped with the locking slot 311 through the protrusion 331, which is convenient for quick detachment and installation. It should be appreciated that when the second locking member 32 is movably disposed, the second locking member 32 is also coupled to the driving member 33 in a similar snap-fit manner.

As shown in fig. 6, the driving member 33 may be a rod-shaped driving member 33. The rod driver 33 includes a screw, an electric push rod, or a cylinder push rod. These drive members 33 can each be used to automate the control of the controllable locking mechanism 30. Taking a screw as an example, two ends of the screw can be connected with the support frame 10 by screw threads. The first locking member 31 is snapped onto the threaded rod. Rotating the screw may move the first locking member 31, thereby achieving either a locked state or an unlocked state of the controllable locking mechanism 30. For example, forward rotation of the screw may move first locking member 31 toward second locking member 32, and reverse rotation of the screw may move first locking member 31 away from second locking member 32.

In practice, one actuator 33 may be provided for each controllable locking mechanism 30. When the weld bead pressing apparatus includes a plurality of controllable locking mechanisms 30, at least two controllable locking mechanisms 30 may share one driving member 33. At this time, the number of the driving members 33 used in the solder strip hold-down device can be reduced, the structure can be simplified, and the cost can be reduced. Also, fewer actuators 33 facilitate uniform control of multiple controllable latching mechanisms 30.

It should be understood that for convenience of snapping a plurality of first locking members 31 sharing a common driving member 33 on the driving member 33, the first locking members 31 may be provided with through-holes 312 for allowing the driving member 33 to pass through. And, the second locking member 32 of the controllable locking mechanism 30 sharing one driving member 33 and the corresponding pressing member set 20 are both provided with mounting holes 312 for the driving member 33 to pass through.

The above description is only for the specific embodiments of the present invention or the description of the specific embodiments, the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. The protection scope of the present invention shall be subject to the protection scope of the claims.
