[0043] This invention discloses a welding strip cutting unit to improve cutting efficiency.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] like Figures 1-4 As shown, this embodiment of the invention provides a solder strip cutting unit, including: a support platform 116 having multiple solder strip placement positions; and a cutting blade assembly that moves relative to the support platform 116 and cuts solder strips 119 at the multiple solder strip placement positions. The cutting blade assembly includes: a cutting blade driving component 101; a cutting blade mounting component 105 driven by the cutting blade driving component 101; and multiple cutting blades 110 mounted on the cutting blade mounting component 105, with the multiple cutting blades 110 corresponding to the multiple solder strip placement positions.

[0046] The solder ribbon cutting unit provided in this embodiment of the invention has multiple solder ribbon placement positions on the support platform 116, which allows multiple solder ribbons 119 to be fixed simultaneously. The cutting blade assembly moves relative to the support platform 116 to cut the solder ribbons 119 at the multiple placement positions, thus completing the operation of cutting multiple solder ribbons 119 together and effectively improving cutting efficiency. Furthermore, by using multiple cutting blades 110 mounted on the cutting blade mounting member 105, the cutting blade driving member 101 drives the cutting blade mounting member 105 to move, ensuring that the multiple cutting blades 110 correspond one-to-one with the solder ribbons 119 at the multiple placement positions for cutting. This reduces the stroke of a single cutting blade 110 cutting the solder ribbon 119, further improving cutting efficiency.

[0047] The correspondence between multiple cutting blades 110 and multiple solder strip placement positions means that the spacing between the multiple cutting blades 110 corresponds to the spacing between the multiple solder strip placement positions (the cutting blades 110 can move relative to the solder strip placement positions).

[0048] Specifically, the welding strip placement position is a location on the support platform 116 for placing multiple welding strips 119, and the cutting blade assembly is located on the side of the support platform 116.

[0049] Alternatively, only one cutting blade 110 can be set up, and the cutting blade mounting part 105 is driven by the cutting blade driving part 101, which in turn drives the cutting blade 110 to cut the welding strips 119 at multiple welding strip placement positions in sequence. Among them, the cutting blade driving part 101 is preferably a power cylinder.

[0050] Furthermore, to ensure the cutting effect of the weld strip 119, the cutting blade assembly also includes a transverse carrier plate 120 connected to the drive end of the cutting blade drive component 101, a cutting blade limiting structure, and a cutting blade driving structure. The transverse carrier plate 120 can move laterally relative to the support platform 116. The moving direction of the transverse carrier plate 120 is the arrangement direction of the multiple weld strip placement positions. The transverse carrier plate 120 is slidably connected to the cutting blade mounting component 105. The sliding direction of the transverse carrier plate 120 and the cutting blade mounting component 105 is set at an angle to the arrangement direction of the multiple weld strip placement positions. The cutting blade limiting structure is used to limit contact with the transverse carrier plate 120. The cutting blade driving structure is used to drive the transverse carrier plate 120 and the cutting blade mounting component 105 to slide. The cutting blade driving component 101 drives the transverse carrier plate 120 to move along the arrangement direction of multiple welding strip placement positions. After the cutting blade limiting structure makes contact with the transverse carrier plate 120, the cutting blade mounting component 105 moves along the arrangement direction of multiple welding strip placement positions to the position corresponding to the welding strip 119 positioned by the multiple welding strip placement positions. The cutting blade driving structure is used to drive the transverse carrier plate 120 and the cutting blade mounting component 105 to slide, realizing the cutting at an angle to the arrangement direction of multiple welding strip placement positions, thus ensuring the cutting effect.

[0051] In this embodiment, preferably, the sliding direction of the transverse carrier plate 120 and the cutter mounting member 105 is perpendicular to the arrangement direction of the plurality of solder strip placement positions, such as the cutter mounting member 105 moving vertically downward relative to the transverse carrier plate 120. Alternatively, the angle between the sliding direction of the transverse carrier plate 120 and the cutter mounting member 105 and the arrangement direction of the plurality of solder strip placement positions can be set to other angles, such as 45° or 60°, etc., which will not be elaborated here and are all within the scope of protection.

[0052] Preferably, a linear guide rail 106 is provided between the cutter mounting component 105 and the transverse transfer plate 120 to ensure the sliding stability of the transverse transfer plate 120.

[0053] The cutter mounting component 105 is connected to the transverse carrier plate 120 via a linear guide rail 106. Preferably, the linear guide rail 106 is a guide rail for the longitudinal movement of the transverse carrier plate 120, so as to facilitate the longitudinal displacement of the cutter 110 to cut the welding strip 119.

[0054] To simplify the structure and reduce the space occupied by the welding strip cutting unit, the cutting blade drive component 101 can drive the transverse carrier plate 120 to move the cutting blade mounting component 105 along the arrangement direction of multiple welding strip placement positions. After being limited by the cutting blade limiting structure, the cutting blade drive component 101 then acts as the power device for the cutting blade driving structure, causing the transverse carrier plate 120 and the cutting blade mounting component 105 to slide relative to each other. The cutting blade assembly also includes an elastic connection mechanism 108, which is connected between the drive end of the cutting blade drive component 101 and the transverse carrier plate 120. The cutting blade driving structure includes a guide component 104 and a follower component 103. The guide component 104 is fixedly connected to the cutting blade mounting component 105 and has an inclined guide surface that is inclined upward in a direction away from the cutting blade drive component 101. The follower component 103 is connected to the drive end of the cutting blade drive component 101 and can contact the inclined guide surface and slide along the inclined guide surface.

[0055] To facilitate the repositioning of the transverse carrier plate 120 and the cutter mounting component 105, the cutter drive structure also includes an elastic repositioning component 107. One end of the elastic repositioning component 107 is connected to the cutter mounting component 105, and the other end is connected to the transverse carrier plate 120. Preferably, the elastic repositioning component 107 is a tension spring. It can also be other elastic blocks or elastic telescopic rods, etc.

[0056] To improve the stability of the follower component 103 sliding along the inclined guide surface, the cutting blade drive structure also includes a follower block 109. The follower block 109 is fixed to the transverse carrier plate 120 and is directly connected to the other end of the elastic connecting device 108. A channel is formed between the follower block 109 and the guide member 104 for the follower component 103 to pass through. It can be understood that the inclined guide surface is the side of the guide member 104 facing the follower block 109, and the side of the follower block 109 facing the guide member 104 is a limiting surface used to restrict the follower component 103 from moving away from the guide member 104.

[0057] Preferably, the guide 104 is a wedge-shaped fastener. The follower 103 is preferably a cam follower.

[0058] The cutter drive component 101 can drive the transverse carrier plate 120 to move the cutter mounting component 105 along the arrangement direction of the multiple welding strip placement positions; after being limited by the cutter limiting structure, the drive end of the cutter drive component 101 continues to move, causing the elastic connecting mechanism 108 to compress and causing the follower component 103 to continue to move along the arrangement direction of the multiple welding strip placement positions; until the follower component 103 contacts the inclined guide surface and slides along the inclined guide surface; since the inclined guide surface is inclined upward in the direction away from the cutter drive component 101, the guide component 104 and the cutter mounting component 105 overcome the elastic restoring force of the elastic reset component 107 and move downward, realizing the relative sliding of the cutter mounting component 105 and the transverse carrier plate 120.

[0059] Of course, an additional drive unit can be added to drive the cutter mounting piece 105 to slide relative to the transverse carrier plate 120.

[0060] To facilitate limit adjustment, the cutter limiting structure includes a cutter limiting screw mounting part 111 and a first limiting screw 112 disposed on the cutter limiting screw mounting part 111. The end of the first limiting screw 112 is used to make limiting contact with the transverse carrier plate 120. By rotating the first limiting screw 112 relative to the cutter limiting screw mounting part 111, the position of the first limiting screw 112 relative to the cutter limiting screw mounting part 111 is adjusted, so as to adjust the position of the end of the first limiting screw 112, thereby realizing the adjustment of the position of the transverse carrier plate 120 after the cutter limiting structure makes limiting contact with the transverse carrier plate 120.

[0061] Of course, the cutting blade limiting structure can also be set to a non-adjustable limiting structure, or set to other common limiting structures that can limit the position of the horizontal carrier plate 120, such as limiting plates or limiting blocks, etc., which will not be described in detail here.

[0062] Preferably, the cutting assembly further includes a lower cutting blade 205 for cooperating with the plurality of cutting blades 110 for cutting, the lower cutting blade 205 being located below the plurality of solder strip placement positions. That is, during the relative sliding process between the cutting blade mounting member 105 and the transverse carrier plate 120, the plurality of cutting blades 110 on the cutting blade mounting member 105 move toward the lower cutting blade 205, and the solder strip 119 to be cut is located between the cutting blades 110 and the lower cutting blade 205, and the cutting of the solder strip 119 is completed by the movement of the cutting blades 110 toward the lower cutting blade 205.

[0063] To facilitate the fixing of the solder ribbon, the support platform 116 (corresponding to the location of the solder ribbon placement position) has adsorption holes for adsorbing the solder ribbon. These adsorption holes connect to external vacuum equipment. The adsorption holes provide an adsorption force on the solder ribbon after it is placed on the support platform 116, ensuring the solder ribbon's position is stable and preventing it from shifting during the cutting process. Furthermore, the adsorption force is not so strong that it would prevent the solder ribbon from moving during the positioning process. Of course, other forms can be used to facilitate solder ribbon fixing, such as providing grooves.

[0064] like Figure 1 and Figure 2 As shown, the transverse transfer plate 120 is mounted on the support side plate 201 via a linear guide rail 204 and a linear guide rail mounting component 203. The support side plate 201 is connected to the mounting base plate 114, and the mounting base plate 114 is fixedly connected to the support platform 116. The linear guide rail 204 serves as a guide rail for the transverse movement of the transverse transfer plate 120, facilitating the transverse displacement of the cutter 110 to the welding strip position, thereby limiting the position of the cutter 110. The cutter drive component 101 pushes the upper cutter 110 to move laterally via an elastic connection mechanism 108.

[0065] Furthermore, it also includes a guide rod structure, one end of which is fixedly connected to one of the drive ends of the follower pressure block 109 and the cutter drive component 101, and the other end of which is slidably engaged with the other of the drive ends of the follower pressure block 109 and the cutter drive component 101.

[0066] Each welding strip cutting unit also includes a guide rod (not labeled in the figure). The follower block 109 has a through channel, and the guide rod is embedded in the through channel between the elastic connecting device 108 (spring) and the follower block 109. One end of the guide rod (via the connector 102) is connected to the cutting blade drive component 101, and the other end is movably disposed in the through channel of the follower block 109. The other end of the guide rod can even protrude out of the through channel. The guide rod facilitates the lateral reset of the cutting blade 110 after cutting and also prevents the elastic connecting device 108 from tilting.

[0067] Furthermore, to facilitate ribbon positioning, the ribbon cutting unit also includes a ribbon positioning structure, which includes a ribbon positioning mechanism 118 that moves relative to the support platform 116 and a ribbon positioning drive device that drives the ribbon positioning mechanism 118 to move relative to the support platform 116. The ribbon placement position also has a limiting structure 117 on another side. The moving direction of the ribbon positioning mechanism 118 is the same as the arrangement direction of the multiple ribbon placement positions. The ribbon positioning mechanism 118 has a limiting structure 305 on one side; the ribbon is located between the limiting structure 305 on one side and the limiting structure 117 on the other side. By driving the ribbon positioning mechanism 118 to move relative to the support platform 116 through the ribbon positioning drive device, the ribbon can move closer to or further away from the limiting structure 305 on one side and the limiting structure 117 on the other side, thereby achieving the positioning and contact of the ribbon.

[0068] Preferably, the welding strip limiting drive mechanism and the cutting blade drive component 101 of the cutting blade assembly are the same component; it also includes a linkage device for causing the transverse carrier plate 120 of the cutting blade assembly to move the welding strip positioning mechanism 118. That is, the cutting blade drive component 101 can also drive the welding strip positioning mechanism 118 to move, so that the limiting structure 305 on one side moves closer to and further away from the limiting structure 117 on the other side, thereby completing the positioning of the welding strip. Furthermore, in addition to providing driving force for limiting the welding strip 119, the cutting blade drive component 101 can also provide driving force for the aforementioned limiting and cutting actions of the cutting blade 110.

[0069] Furthermore, the welding strip positioning mechanism 118 includes a positioning rod 302; the positioning rod 302 is provided with a one-sided limiting structure 305, and the positioning rod 302 passes through the support platform 116. This configuration effectively improves structural compactness, thereby reducing the floor space. It also allows the positioning rod 302 to slide on the surface of the support platform 116. The linkage device includes a pushing structure and a pushing block 206; the pushing structure is located at one end of the positioning rod 302, and the driving end of the welding strip limiting drive device pushes the pushing structure to move; the pushing block 206 is fixed to the transverse carrier plate 120. During the movement of the transverse carrier plate 120 driven by the cutter drive component 101, the pushing block 206 contacts the pushing structure to facilitate the movement of the positioning rod 302, ultimately achieving the approach and distance between the one-sided limiting structure 305 and the other-sided limiting structure 117.

[0070] A push block 206 is fixed on the transverse transfer plate 120. The push block 206 contacts the end of the second limit screw 113 to realize the pushing action of the welding strip positioning mechanism 118. The push block 206 can be integral with the transverse transfer plate 120, or the push block 206 can be fixed to the transverse transfer plate 120 by welding or connecting the push block 206 to the transverse transfer plate 120.

[0071] Furthermore, an anti-detachment component is provided at the other end of the positioning rod 302. After the drive end of the welding strip limiting drive device pushes the pushing structure a predetermined distance, the anti-detachment component can abut against the support platform 116. After the drive end of the welding strip limiting drive device pushes the pushing structure, the limiting structure 305 on one side of the positioning rod 302 moves, realizing the clamping and positioning of the welding strip. During this process, the anti-detachment component does not contact the support platform 116. In order to prevent the positioning rod 302 from separating from the support platform 116 under the action of inertia or pushing force, the anti-detachment component can abut against the support platform 116, restricting the positioning rod 302 from continuing to move.

[0072] To avoid hard contact, the anti-detachment component is an elastic contact component 301. The elastic contact component 301 is located at the other end of the positioning rod 302 and is used to abut against the side wall of the support platform 116.

[0073] Furthermore, the pushing structure includes a ribbon limiting screw mounting part 115 and a second limiting screw 113 disposed on the ribbon limiting screw mounting part 115. The end of the second limiting screw 113 is used for limiting contact with the drive end of the ribbon limiting drive device. By rotating the second limiting screw 113 relative to the ribbon limiting screw mounting part 115, the position of the second limiting screw 113 relative to the ribbon limiting screw mounting part 115 is adjusted, so as to adjust the position of the end of the second limiting screw 113, thereby adjusting the contact position between the pushing structure and the drive end of the ribbon limiting drive device, and thus adjusting the pushing distance of the pushing structure. Of course, the pushing structure can also be configured with other common structures, such as a pushing rod connected to the ribbon positioning mechanism 118, etc., which will not be described in detail here.

[0074] Specifically, since the welding strip limiting drive mechanism and the cutter drive component 101 of the cutter assembly are the same component, the transverse carrier plate 120 of the cutter assembly has a push block 206 that makes limiting contact with the end of the second limiting screw 113, driving the positioning rod 302 to move, thereby achieving the positioning of the welding strip. Afterwards, the cutter drive component 101 continues to drive, and the end of the first limiting screw 112 makes limiting contact with the transverse carrier plate 120, completing the limiting of the cutter 110. Then, the cutter drive component 101 continues to drive, causing the transverse carrier plate 120 to slide relative to the cutter mounting component 105, performing a cutting action on the welding strip.

[0075] To improve the moving stability of the transverse carrier plate 120, the transverse carrier plate 120 is fixed to the mounting side plate 201 by the linear guide rail 204 and the linear guide rail mounting part 203. The second limit screw 113 is connected to N (N≥1) welding strip positioning mechanisms 118 by the limit screw mounting part 115. The position of the limit screw 113 is set to correspond to the push block 206.

[0076] Preferably, the welding strip positioning mechanism 118 further includes an elastic connector 303 and a slider 304 that slides relative to the positioning rod 302. The elastic connector 303 connects the positioning rod 302 and the slider 304; a one-sided limiting structure 305 is fixedly connected to the slider 304. This arrangement avoids hard contact between the one-sided limiting structure 305 and the welding strip 119, preventing damage to the welding strip during pushing.

[0077] Furthermore, the positioning rod 302 has a slotted structure, and the slider 304 and the elastic connector 303 are disposed within the slotted structure. One end of the elastic connector 303 contacts one side of the slot wall within the slotted structure, and the other end of the elastic connector 303 abuts against the slider 304. The slider 304 has a one-sided limiting structure 305. This design improves the structural compactness. Alternatively, a groove that mates with the slider 304 can also be provided on the positioning rod 302.

[0078] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0079] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
