[0039] like Figure 1-Figure 3 As shown, the tin wire tensioning equipment according to the embodiment of the present application includes: a frame 10, a feeding mechanism 20, a tin wire pulling mechanism 30, a tensioning mechanism 40, a control mechanism and a first detection mechanism 50.

[0040] Specifically, the feeding mechanism 20 is used to convey the tin wire 1; the tin wire pulling mechanism 30 includes a power component 31 and a first clamping jaw component 32, the first clamping jaw component 32 is transmission-connected to the power component 31 to drive the first clamping jaw component 32 to move, and the first clamping jaw component 32 is used to clamp and stretch the tin wire 1; the tensioning mechanism 40 is arranged between the feeding mechanism 20 and the tin wire pulling mechanism 30, the tensioning mechanism 40 includes a connecting rod 41 and a test piece 42, the connecting rod 41 is swingably arranged on the frame 10, and the connecting rod 41 is provided with a first wire groove 431 and the test piece 42, and the first wire groove 431 is used to clamp the tin wire 1; the first detection mechanism 50 is arranged relative to the test piece 42 for detecting the position of the test piece 42; the control mechanism is electrically connected to the first detection mechanism 50 and the feeding mechanism 20.

[0041] In detail, the feeding mechanism 20 is used to feed the tin wire tensioning equipment, and the tin wire pulling mechanism 30 uses the power component 31 to provide power for the movement of the first clamping jaw component 32, so that the first clamping jaw component 32 can move to a suitable position to clamp the tin wire 1 and drive the tin wire 1 to move for tensioning. The tensioning mechanism 40 is arranged between the feeding mechanism 20 and the tin wire pulling mechanism 30. The tensioning mechanism 40 is used to tension the tin wire 1, so as to facilitate the first clamping jaw component 32 to tension the tin wire 1, wherein the first wire passing groove 431 is used to limit the tin wire 1, and the tin wire 1 is clamped in the first wire passing groove 431. The connecting rod 41 is gradually pulled up by the tin wire 1 during the tensioning process, and the connecting rod 41 gradually falls down during the process of the tin wire 1 being relaxed after the feeding mechanism 20 is loaded. Therefore, the first detection mechanism 50 detects the position of the test piece 42 to determine when to control the feeding mechanism 20 to load.

[0042] It should be noted that Figure 1 The middle dashed line shows an example in which the link 41 swings to one of the positions.

[0043] According to the tin wire tensioning device of the embodiment of the present application, the connecting rod 41 swings to tension the tin wire 1, which can reduce the gravity on the tin wire 1, and can better achieve uniform tensioning of the tin wire 1 to prevent the tin wire 1 from being broken.

[0044] like Figure 1 and Figure 4 As shown, in a specific embodiment, the feeding mechanism 20 includes a driving unit and a winding drum, the tin wire 1 is wound on the winding drum, and the driving unit is transmission-connected to the winding drum to drive the winding drum to rotate, thereby realizing the feeding of the tin wire 1.

[0045] In a specific embodiment, the connecting rod 41 can swing between a first position and a second position. When the connecting rod 41 is in the second position, the tin wire 1 is tensioned. When the connecting rod 41 is in the first position, the test piece 42 can be sensed by the first detection mechanism 50. The specific control process is as follows:

[0046] When the tin wire 1 is gradually tightened under the tension of the first clamping jaw assembly 32 so that the connecting rod 41 is pulled away from the first position, the first detection mechanism 50 detects that the connecting rod 41 is out of the first position. At this time, feedback is given to the control mechanism, and the control mechanism controls the feeding mechanism 20 to start feeding. During the feeding process, as the tin wire 1 is gradually relaxed, the connecting rod 41 gradually falls down under the action of gravity and falls back to the first position again. When the first detection mechanism 50 detects that the connecting rod 41 is in the first position, feedback is given to the control mechanism, and the control mechanism controls the feeding mechanism 20 to stop feeding. Among them, the first detection mechanism 50 determines the position of the connecting rod 41 by detecting the position of the test piece 42.

[0047] like Figure 2 and Figure 4As shown, according to the tin wire tensioning equipment of the embodiment of the present application, a first pulley 43 is provided on the connecting rod 41, a first wire passing groove 431 is provided on the circumference of the first pulley 43, a second pulley 44 is provided between the first pulley 43 and the first clamping jaw assembly 32, a second wire passing groove is provided on the second pulley 44, and the second wire passing groove is used to clamp the tin wire 1.

[0048] In detail, the first pulley 43 and the second pulley 44 assist in tensioning and positioning the tin wire 1, which can reduce unnecessary friction during the conduction of the tin wire 1, so that when the first clamping jaw assembly 32 tensions the tin wire 1, it is easier to tension the tin wire 1 at a uniform speed at all locations and it is not easy to break.

[0049] like Figure 2 and Figure 4 As shown, in some embodiments, the connecting rod 41 can swing between a first position and a second position, the first position being the position where the connecting rod 41 naturally hangs down under the action of gravity, and the projections of the first pulley 43 in the first position and in the second position are both located on the side of the second pulley 44 close to the first clamping jaw assembly 32 when projected in a horizontal plane. Figure 1 The dashed line illustrates that the connecting rod 41 is in the first position, and the solid line illustrates that the connecting rod 41 is in the second position. Figure 2 The solid line illustrates that the connecting rod 41 is in the second position. Figure 2 The dashed line illustrates that the connecting rod 41 is in the first position. Figure 4 The dashed line illustrates that the connecting rod 41 is in the second position, and the solid line illustrates that the connecting rod 41 is in the first position.

[0050] In detail, the connecting rod 41 can swing between the first position and the second position (the swing of the connecting rod 41 is caused by the pulling of the tin wire 1), and the first position is the position where the connecting rod 41 naturally hangs down under the action of gravity, that is, at this time, the connecting rod 41 is subjected to the force of the tin wire 1, and the tin wire 1 is sufficiently relaxed, and the control mechanism controls the feeding mechanism 20 to suspend feeding when the connecting rod 41 moves to the first position, which can avoid the tin wire 1 from being excessively relaxed and causing uneven tension. Projected in the horizontal plane, the projections of the first pulley 43 when it is in the first position and in the second position are both located on the side of the second pulley 44 close to the first clamping jaw assembly 32. When the first pulley 43 is pulled to the second position, the feeding mechanism 20, the first pulley 43 and the second pulley 44 form a triangular relationship, so that when the first pulley 43 is pulled to the second position, the tin wire 1 can still be effectively tensioned.

[0051] like Figure 1 , Figure 3 as well as Figure 4As shown, according to the tin wire tensioning device of the embodiment of the present application, the power assembly 31 includes a first drive group 311, the tin wire pulling mechanism 30 includes a second clamping jaw assembly 33, the second clamping jaw assembly 33 is spaced apart from the first clamping jaw assembly 32, the first drive group 311 drives the first clamping jaw assembly 32 to move along a first direction toward or away from the second clamping jaw assembly 33, and the second clamping jaw assembly 33 is used to clamp the tin wire 1.

[0052] In detail, the power component 31 includes a first drive group 311, and the tin wire pulling mechanism 30 includes a second clamping jaw assembly 33. The second clamping jaw assembly 33 is spaced from the first clamping jaw assembly 32. The first clamping jaw assembly 32 and the second clamping jaw assembly 33 are both used to clamp the tin wire 1. The first drive group 311 drives the first clamping jaw assembly 32 to move along the first direction toward or away from the second clamping jaw assembly 33. When the tin wire 1 is tensioned, the second clamping jaw assembly 33 clamps the tin wire 1. The first clamping jaw assembly 32 is driven by the first drive group 311 to approach the second clamping jaw group to clamp the tin wire 1. After clamping the tin wire 1, the second clamping jaw assembly 33 releases the tin wire 1. The first drive group 311 drives the first clamping jaw group to move in a direction away from the second clamping jaw group, thereby tensioning the tin wire 1. The cooperation between the second clamping jaw assembly 33 and the first clamping jaw assembly 32 can fix the tin wire 1, which is conducive to the uniform stretching of the tin wire 1 during the tensioning process.

[0053] like Figure 4 and Figure 6 As shown, in some embodiments, the power assembly 31 also includes a second drive group 312, the second drive group 312, the first drive group 311 and the first clamping jaw assembly 32 are sequentially connected in transmission, and the second drive group 312 drives the first clamping jaw assembly 32 to move along the second direction.

[0054] In detail, the power assembly 31 also includes a second drive group 312. The second drive group 312, the first drive group 311 and the first clamping jaw assembly 32 are sequentially connected in transmission. The second drive group 312 drives the first clamping jaw assembly 32 to move along the second direction. In this way, the position of the first clamping jaw assembly 32 can be adjusted in multiple directions to better tension the tin wire 1.

[0055] like Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, the power assembly 31 also includes a third drive group 313, and the third drive group 313, the second drive group 312, the first drive group 311 and the first clamping jaw assembly 32 are sequentially connected in transmission, and the third drive group 313 is used to drive the first clamping jaw assembly 32 to move along the third direction, and the first direction, the second direction and the third direction are perpendicular to each other.

[0056] Specifically, the power assembly 31 includes a third drive group 313, and the third drive group 313, the second drive group 312, the first drive group 311 and the first clamping jaw assembly 32 are sequentially connected in transmission. The third drive group 313 drives the second drive group 312, the first drive group 311 and the first clamping jaw assembly 32 to move along the third direction as a whole, thereby driving the first clamping jaw assembly 32 to move along the third direction. In this way, the position of the first clamping jaw assembly 32 can be adjusted in multiple directions to better tension the tin wire 1.

[0057] In a specific embodiment, the second drive group 312 and the third drive group 313 are configured as cylinder drives.

[0058] like Figure 1 , Figure 3 as well as Figure 4 As shown, in some embodiments, the first drive group 311 includes a motor, a first transmission wheel 3112, a second transmission wheel 3113, a transmission belt 3114 and a connecting member 3115. The motor is connected to the first transmission wheel 3112 in transmission connection. The first transmission wheel 3112 and the second transmission wheel 3113 are arranged at intervals.

The transmission belt 3114 is connected to the connecting member 3115, and the connecting member 3115 is connected to the first clamping jaw assembly 32.

[0059] Specifically, the first drive group 311 includes a motor, a first transmission wheel 3112, a second transmission wheel 3113, a transmission belt 3114 and a connecting member 3115. The motor is connected to the first transmission wheel 3112, the first transmission wheel 3112 and the second transmission wheel 3113 are arranged at intervals, and the transmission belt 3114 is sleeved on the first transmission wheel 3112 and the second transmission wheel 3113. The motor drives the first transmission wheel 3112 to rotate, and the first transmission wheel 3112 rotates to drive the transmission belt 3114 to rotate, and the transmission belt 3114 rotates to drive the connecting member 3115 to move, and the connecting member 3115 moves to drive the first clamping jaw assembly 32 to move, so that the first clamping jaw assembly 32 can be driven to move more evenly. For example, compared with the cylinder driving the first clamping jaw assembly 32 to move and stretch the tin wire 1, the moving speed of the cylinder may be uneven due to changes in air pressure.

[0060] like Figure 3 and Figure 6As shown, in a specific embodiment, the tin wire tensioning device further includes a fourth drive group 314, which is disposed on the frame 10, and the fourth drive group 314, the third drive group 313, the third drive group 313, the second drive group 312, the first drive group 311 and the first clamping jaw assembly 32 are sequentially connected in transmission. The fourth drive group 314 drives the first clamping jaw assembly 32 to move along the first direction. Since the first drive group 311 has a travel limit on the moving range of the first clamping jaw assembly 32, the fourth drive group 314 can be used to adjust the position of the first clamping jaw assembly 32 within a larger range.

[0061] like Figure 3 and Figure 6 As shown, in some embodiments, the second driving group 312 includes a driving cylinder 3121 and a fixed plate 3122, the piston end of the driving cylinder 3121 is connected to the fixed plate 3122, the motor, the first transmission wheel 3112 and the second transmission wheel 3113 are all arranged on the fixed plate 3122, the fixed plate 3122 is provided with a slide rail 3123, the connecting end of the first clamping jaw assembly 32 is provided with a slide groove, and the slide rail 3123 is clamped in the slide groove.

[0062] In detail, the second driving group 312 includes a driving cylinder 3121 and a fixed plate 3122. The piston end of the driving cylinder 3121 is connected to the fixed plate 3122. The second driving group 312 drives the fixed plate 3122 to move as a whole along the second direction. A slide rail 3123 is provided on the fixed plate 3122. A slide groove is provided at the connecting end of the first clamping jaw assembly 32. The slide rail 3123 is engaged with the slide groove, so that the slide rail 3123 cooperates with the slide groove to provide a guiding effect on the movement of the first clamping jaw assembly 32, so that the movement of the first clamping jaw assembly 32 is more stable.

[0063] like Figure 3 As shown, in some embodiments, two spaced second detection mechanisms 60 are provided on the fixed plate 3122 along the first direction, and the two second detection mechanisms 60 are respectively located on both sides of the first clamping jaw assembly 32, and the second detection mechanism 60 and the motor are electrically connected to the control mechanism, and the second detection mechanism 60 is used to detect the position of the first clamping jaw assembly 32.

[0065] Among them, the first detection mechanism 50 can be a sensor, and the second inspection mechanism can be a sensor, which is not limited in this application.

[0066] like Figure 5 As shown, in some embodiments, a guide member 11 is further provided on the frame 10 , and the guide member 11 defines a wire groove for sleeved tin wire 1 , and the guide member 11 is located between the first clamping jaw assembly 32 and the second clamping jaw assembly 33 .

[0067] In detail, the wire groove is used to keep the tin wire 1 linear, and the guide member 11 is located between the first clamping jaw assembly 32 and the second clamping jaw assembly 33. During the tensioning process of the tin wire 1, it provides a guiding function, which can better enable the tin wire 1 to be tensioned at a uniform speed to avoid breaking.
