[0030] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] Embodiment 1:

[0032] As Figure 1 shown, a needle wiping device includes a clamping and wiping assembly 1. The clamping and wiping assembly 1 is provided with a needle wiping gap 11. The clamping and wiping assembly 1 is movably connected to a wiping belt 2. The wiping belt 2 passes through the needle wiping gap 11. The wiping belt 2 is connected to a feeding and receiving assembly 3. The feeding and receiving assembly 3 can drive the wiping belt 2 to move relative to the needle wiping gap. By driving the wiping belt 2 to move on the needle wiping gap 11 through the feeding and receiving assembly 3, the wiping belt 2 that has already wiped the needle 5 is taken away, and the unwiped wiping belt 2 is replaced, so as to ensure that the residue left by needle wiping will not adhere to the needle 5 during the next wiping process, and ensure the quality of each wiping. The needle wiping gap 11 provides an avoidance space for the movement of the needle, and enables the wiping belt 2 to be extruded by the needle into the needle wiping gap 11 in a straightened state, so as to realize the full wrapping of the wiping belt 2 around the needle.

[0033] As Figure 1 shown, the feeding and receiving assembly 3 includes a feeding wheel 31 and a receiving wheel 32. Both ends of the wiping belt 2 are respectively wound around the feeding wheel 31 and the receiving wheel 32. A tape guide wheel 33 is arranged between the receiving wheel 32 and / or the feeding wheel 31 and the clamping and wiping assembly 1. The tape guide wheel 33 abuts against the wiping belt 2. The feeding and receiving assembly 3 includes a conveying driving member 34. The conveying driving member 34 is arranged between the feeding wheel 31 and the receiving wheel 32, and the conveying driving member 34 is arranged on the side of the clamping and wiping assembly 1 away from the needle.

[0034] By winding the wiping belt 2 around the feeding wheel 31 and the receiving wheel 32, the conveying of the wiping belt 2 is made stable, and the storage of the wiping belt 2 is improved, ensuring the integration of the whole device. A tape guide wheel 33 is arranged on the movement path of the wiping belt 2. By abutting against the wiping belt 2 through the tape guide wheel 33, guiding and tensioning are provided for the wiping belt 2, ensuring the movement stability of the wiping belt 2. By driving the receiving wheel 32 and the feeding wheel 31 to move through the conveying driving member 34, and arranging the conveying driving member 34 between the receiving wheel 32 and the feeding wheel 31 and on the side of the clamping and wiping assembly 1 away from the needle, the whole needle wiping and gluing assembly can ensure the centering and lower placement of the center of gravity, and ensure the stability of the needle wiping and gluing assembly.

[0035] As Figure 1 、 2As shown, the clamping and wiping assembly 1 includes a clamping driving member 12. The clamping and wiping assembly 1 includes a side clamping block 13 that moves with the clamping driving member 12. A soft clamping pad 14 is provided on the side clamping block 13 near the needle. The clamping and wiping assembly 1 includes a clamping driving member 12. The clamping driving member 12 can drive the side clamping block 13 to move. A soft clamping pad 14 is provided on the side clamping block 13. When the side clamping block 13 moves close to the needle, the soft clamping pad 14 clamps the needle. Since the material of the soft clamping pad 14 is softer, it can deform after contacting the needle, thereby increasing the contact area with the needle and improving the wrapping property during the wiping process.

[0036] As Figure 3 As shown, a material shortage detection component 4 is provided on the extending path of the wiping belt 2. The wiping belt 2 includes a feeding section 22 and a collecting section 23. The material shortage detection component 4 is provided on the side close to the feeding section 22. A material shortage detection component 4 is also provided in this device, which can give a timely reminder when the wiping belt 2 is insufficient and prompt for replacement. The material shortage detection component 4 is arranged on the side of the feeding section 22, so as to accurately detect the shortage of the wiping belt 2.

[0037] In this embodiment, the assembly and working process of the needle wiping device are as follows: In this embodiment, a bottom plate for installing the clamping and wiping assembly 1 and the feeding and collecting assembly 3 is provided. The feeding and collecting assembly 3 includes a feeding wheel 31 and a collecting wheel 32. The feeding wheel 31 and the collecting wheel 32 are symmetrically arranged on both sides respectively. The feeding and collecting assembly 3 further includes a conveying driving member 34. The conveying driving member 34 is arranged between the feeding wheel 31 and the collecting wheel 32 and is arranged below the clamping and wiping assembly 1. In this embodiment, a tape guide wheel 33 is provided on the side of the feeding wheel 31 and the collecting wheel 32 close to the clamping and wiping assembly 1 respectively. The tape guide contacts the wiping belt 2, tensions the wiping belt 2 and provides a guiding function for the wiping belt 2.

[0038] In this embodiment, the wiping belt 2 includes a wiping section 21 near the needle wiping gap 11 in the clamping and wiping assembly 1. On one side of the wiping section 21 close to the feeding wheel 31 and the receiving wheel 32 are the feeding section 22 and the receiving section 23 respectively. In this embodiment, two tape guide wheels 33 are provided, and the tape guide wheels are respectively located at the positions where the feeding section 22 and the receiving section 23 are located, and the two tape guide wheels 33 respectively abut against the wiping belt 2 on the feeding section 22 and the receiving section 23. Further, in this embodiment, the tape guide wheels 33 respectively tension the wiping belt 2 on the feeding section 22 and the receiving section 23 into an obtuse angle structure. In this embodiment, with the needle moving downward into the needle wiping gap 11 as the moving direction, the wiping belt 2 is wound around the feeding wheel 31, then extends upward to abut against the tape guide wheel 33 on the feeding section 22. After passing through the tape guide wheel 33, it continues to extend upward to the clamping and wiping assembly 1, extends horizontally on the clamping and wiping assembly 1, passes through the entire clamping and wiping assembly 1, then extends downward to abut against the receiving wheel 32 on the receiving section 23, and then continues to extend downward to the receiving wheel 32.

[0039] In this embodiment, when the wiping belt 2 is at the needle wiping gap 11, there is a void structure below the wiping belt 2. The wiping belt 2 of the wiping section 21 relies on the tension on both sides to maintain its movement at the needle wiping gap 11. When needle wiping is required, the needle moves downward to abut against the wiping belt 2 and continues to move downward to an ideal position. At this time, the movement of the needle overcomes the tension effect of the wiping belt 2 and squeezes the part on the wiping section 21 downward, so that the wiping section 21 wraps around the needle at the needle wiping gap 11. Subsequently, the clamping and driving member 12 drives the side clamping blocks 13 on both sides to squeeze the needle. Since there is a wiping belt 2 between the side clamping blocks 13 and the needle, after the needle leaves the needle wiping gap 11, the residual material on the needle is cleaned by the wiping belt 2 on the wiping section 21, achieving the wiping effect on the needle.

[0040] After the needle wiping is completed, the feeding and receiving assembly 3 starts to move, transmits the wiped wiping section 21 toward the receiving wheel 32 side, and moves the unwiped wiping belt 2 on the feeding section 22 to the wiping section 21, waiting for the next wiping action.

[0041] In this embodiment, the conveying driving member 34 is a motor, the clamping and driving member 12 is a cylinder, and the entire needle wiping and gluing device is symmetrically arranged, with the clamping and wiping assembly 1 centered. The movement path of the needle is also in the middle position of the entire device. Further, in this embodiment, a material shortage detection assembly 4 is provided on the clamping and wiping assembly 1. The material shortage detection assembly 4 can detect the conveying path on the wiping belt 2 through a sensor. Further, the wiping belt 2 in this embodiment is arranged on one side of the feeding section 22, so that when the wiping belt 2 on the feeding section 22 is missing, it can be notified in time to replenish the wiping belt 2.

[0042] Example 2:

[0043] As Figure 1 、 2 shown, different from Example 1, in this embodiment, the clamping and wiping assembly 1 includes a guiding surface, the wiping belt 2 abuts against the guiding surface, and limiting side plates 16 are arranged on both sides of the movement path of the wiping belt 2. The clamping and wiping assembly 1 includes a guiding surface that abuts against the wiping belt 2. In order to ensure the smooth movement of the wiping belt 2 without deviation, limiting side plates 16 are arranged on the side of the guiding surface to ensure the smooth operation of the wiping belt 2.

[0044] The clamping and wiping assembly 1 includes a limiting block 15 arranged in the needle wiping gap 11, and the position of the limiting block 15 is aligned with the movement path of the needle. The wiping belt 2 includes a wiping section 21, and the wiping section 21 is arranged on the needle wiping gap 11, and the wiping section 21 is arranged between the limiting block 15 and the needle.

[0045] A limiting block 15 is arranged in the needle wiping gap, and the limiting block 15 can provide a constraint for the traveling distance of the needle. The wiping section 21 of the wiping belt 2 is arranged on the needle wiping gap 11, and the wiping section 21 is arranged between the needle and the limiting block 15 to ensure that when the needle moves close to the side of the limiting block 15, the wiping belt 2 can fully wrap the needle.

[0046] The assembly and working process of the needle wiping device in this embodiment are as follows: In this embodiment, a bottom plate for installing the clamping and wiping assembly 1 and the feeding and discharging assembly 3 is provided. The feeding and discharging assembly 3 includes a feeding wheel 31 and a receiving wheel 32, and the feeding wheel 31 and the receiving wheel 32 are symmetrically arranged on both sides respectively. The feeding and discharging assembly 3 further includes a conveying driving member 34, and the conveying driving member 34 is arranged between the feeding wheel 31 and the receiving wheel 32 and below the clamping and wiping assembly 1. In this embodiment, tape guide wheels 33 are arranged on one side of the feeding wheel 31 and the receiving wheel 32 close to the clamping and wiping assembly 1 respectively. The tape guide abuts against the wiping belt 2 to tension the wiping belt 2 and provide a guiding function for the wiping belt 2.

[0047] In this embodiment, the wiping belt 2 includes a wiping section 21 near the needle wiping gap 11 in the clamping and wiping assembly 1. A guiding surface is provided on the clamping and wiping assembly 1, and the guiding surface is located on the upper side of the clamping and wiping assembly 1. The wiping section 21 is located on the guiding surface. Further, in this embodiment, limiting side plates 16 are provided on the guiding surface, and the limiting side plates 16 are located on both sides of the guiding surface. In this embodiment, since there are two side clamping blocks 13, guiding surfaces are provided on both side clamping blocks 13. The guiding surfaces on both sides and the middle needle wiping gap 11 form the area where the wiping section 21 is located. During the downward movement of the needle, due to the limiting effect of the limiting side plates 16, it can be ensured that the wiping belt 2 will not shift in position during movement. On one side of the wiping section 21 close to the feeding wheel 31 and the winding wheel 32 are respectively a feeding section 22 and a winding section 23. In this embodiment, two tape guiding wheels 33 are provided, and the tape guiding wheels are respectively located at the positions where the feeding section 22 and the winding section 23 are located. The two tape guiding wheels 33 respectively abut against the wiping belt 2 on the feeding section 22 and the winding section 23. Under the guiding action of the tape guiding wheels 33 and the limiting side plates 16, the wiping belt 2 can move along the set route, ensuring the movement stability of the wiping belt 2.

[0048] In this embodiment, when the wiping belt 2 is located on the needle wiping gap 11, there is a gap structure below the wiping belt 2. The wiping belt 2 of the wiping section 21 maintains its movement on the needle wiping gap 11 by the tension on both sides. When needle wiping is required, the needle moves downward and abuts against the wiping belt 2. At this time, the wiping belt 2 on the needle wiping gap 11 receives a downward acting force. Due to the limiting effect of the limiting side plates 16, it can be ensured that the wiping belt 2 moves in a straight downward direction and moves to the ideal position.

[0049] Further, in this embodiment, a limiting block 15 is provided on the needle wiping gap 11. The limiting block 15 is provided at the end of the needle movement path and is arranged between the two side clamping blocks 13. At the same time, furthermore, in this embodiment, soft clamping pads 14 are respectively provided on the opposite surfaces of the two side clamping blocks 13. The setting of the soft clamping pads 14 can not only ensure the wrapping property of the needle clamping, but also prevent interference between the two side clamping blocks 13 and the limiting block 15 during the opposite movement.

[0050] The downward movement of the needle overcomes the tensioning effect of the wiping belt 2, and squeezes the part on the wiping section 21 downward, so that the wiping section 21 wraps the needle on the needle wiping gap 11, and then the clamping drive 12 drives the side clamping blocks 13 on both sides to squeeze the needle. Since the side clamping blocks 13 are provided with soft pads 14, the soft pads 14 are deformed after being subjected to the squeezing force, thereby increasing the contact area with the needle, so that the wiping belt 2 can wrap the needle in all directions. After the needle leaves the needle wiping gap 11, the residual material on the needle is wiped off by the wiping belt 2 in all directions, thereby achieving an all-round wiping effect on the needle.

[0051] After the needle is wiped, the feeding assembly 3 starts to move, transferring the wiped section 21 toward the receiving wheel 32, and moving the unwiped wiping belt 2 on the feeding section 22 to the wiping section 21, waiting for a new round of wiping action.

[0052] In this embodiment, the conveying drive member 34 is a motor, the clamping drive member 12 is a cylinder, the entire needle eraser is symmetrically arranged, the clamping and wiping assembly 1 is centrally arranged, and the movement path of the needle is also in the middle of the entire device. Further, in this embodiment, a material shortage detection assembly 4 is arranged on the clamping and wiping assembly 1, wherein the material shortage detection assembly 4 can detect the conveying path on the wiping belt 2 through sensor detection. Furthermore, the wiping belt 2 in this embodiment is arranged on one side of the feeding section 22, so that when the wiping belt 2 on the feeding section 22 is missing, it can be notified in time to replenish the wiping belt 2.
