[0002] When splicing two bundles of wires, it is necessary to cut off a section of the insulation of each of the two bundles of wires to expose part of the conductor. Each bundle of wires can be composed of one or more wires. Ultrasonic welding is used to splice the exposed conductors of the two bundles of wires, and then a section of insulating heat shrink tubing is wrapped around the exposed conductors. During processing, the insulating heat shrink tubing is heated so that the insulating heat shrink tubing is tightly wrapped around the insulation of the two bundles of wires or is bonded to the insulation, so that the original exposed conductor is covered. During automated processing, the insulating heat shrink tubing needs to be positioned in a preset position in advance, and the exposed conductors need to be completely covered before being heated.

[0041] As Figure 1 shown, the pushing device 100 includes a driving device 110, a transmission mechanism 120, and a pushing and prodding member 130. The driving device 100 generates a driving force, which is transmitted to the pushing and prodding member 130 through the transmission mechanism 120 to move the pushing and prodding member 130. When the pushing and prodding member 130 moves, the pushed member is moved, so that the pushed member is moved to a preset position. When applied to the processing of the wire 200, the pushing device 100 can push the insulating heat-shrinkable sleeve 210 to move to cover the exposed conductor 201 through the pushing and prodding member 130.

[0042] The driving device 110 is a device for generating a driving force, and it can adopt various power output mechanisms, such as a motor, a cylinder, etc. In the example shown in the figure, the driving device 110 is a cylinder, and the driving device 110 has a piston rod 111. The piston rod 111 is telescopically arranged.

[0043] As Figures 1 to 4 shown, according to the technical solution of the present invention, the pushing device 100 further includes a flexible connection device 140. The flexible connection device 140 includes a push rod 141, a connection spring 142, a first stop block 143, and a second stop block 161. The connection spring 142 is sleeved on the push rod 141. The push rod 141 extends from one end 1421 of the connection spring 142 to the other end 1422 to support the connection spring. A flange 144 is provided on the push rod 141. The push rod 141 passes through the first stop block 143 and the second stop block 161, and is provided with a clearance with both the first stop block 143 and the second stop block 161, so that the push rod 141 can move relative to the first stop block 143 and the second stop block 161. The first stop block 143 and the second stop block 161 are arranged at intervals. The flange 144 is located between the first stop block 143 and the second stop block 161. The flange 144 is blocked by the second stop block 161 and cannot cross the second stop block 161. When the push rod 141 moves, the flange 144 can only move between the first bump 143 and the second blocking block 161. The connection spring 142 is located between the flange 144 and the first stop block 143. One end 1421 of the connection spring 142 abuts against the flange 144, and the other end 1422 abuts against the first stop block 143. The flange 144 is located between the first stop block 143 and the second stop block 161 and can move between the two. During the movement of the flange 144, it is blocked by the first and second stop blocks 161 and can contact the second stop block 161. The connecting member 162 connects the first stop block 143 and the second stop block 161.

[0044] The push rod 141 is connected to the piston rod 111. The driving device 110 drives the push rod 141 to move through the piston rod 111. When the push rod 141 moves, it can abut against one end 1421 of the connecting spring 142 through the flange 144, and transmit the driving force to the first stop block 143. When the resistance received by the first stop block 143 is less than the driving force, the connecting spring 142 does not deform or deforms slightly, and the first stop block 143 is driven to move. When the resistance received by the first stop block 143 is greater than the driving force, the connecting spring 142 is compressed and deformed, the push rod 141 moves relative to the connecting spring 142, and the length passing through the first stop block 143 gradually increases.

[0045] A push rod position detection device 145 is arranged on the moving route of the push rod 141. The push rod position detection device 145 can detect whether the push rod 141 reaches the critical position. The push rod position detection device 145 can adopt a proximity switch. When the end of the push rod 141 approaches the push rod position detection device 145, the push rod position detection device 145 outputs a control signal. The host computer can control the operation of the driving device 110 according to the control signal output by the push rod position detection device 145, so that the driving device 110 stops working or drives the push rod 141 to move in the reverse direction.

[0046] The transmission mechanism 120 includes a gear 121 and two racks 122; the two racks 122 are respectively meshed with the gear 121 and are linked through the gear 121. The gear 121 is rotatably arranged. When the gear 121 rotates, it drives the two racks 122 to move linearly and in opposite directions. To maintain the stability of the rack 122 during the movement process, the present invention also provides a guiding device 123 for guiding when the rack 122 moves. In the example shown in the figure, the guiding device 123 includes a guide rail 124 and a slider 125. The slider 125 is arranged in slidable cooperation with the guide rail 124. The slider 125 is fixedly arranged and the guide rail 124 is slidable. The rack 122 is connected to the guide rail 124. One of the racks 122 is fixedly connected to the first stop block 143. The connecting member 162 is also fixedly connected to this rack 122, that is to say, the first stop block 143 can be directly connected to the rack 122, or can be connected to this rack 122 through the connecting member 162. As a solution of an alternative embodiment, the connecting member 162 can also not be connected to the rack 122, but only the first stop block 143 is connected to the rack 122. When the first stop block 143 moves, it drives this rack 122 to move, and then drives the gear 121 to rotate, and further drives the other rack 122 to move.

[0047] As Figure 1 、 Figure 5 、 Figure 6As shown, the pushing and dialing member 130 includes a limiting piece 131 and a blocking piece 132. There is a gap 134 between the limiting piece 131 and the blocking piece 132. The blocking piece 132 is movably arranged, and when the blocking piece 132 moves, the size of the gap 134 is adjusted. In the example shown in the figure, the limiting piece 131 has a U-shaped section 133. The opening of the U-shaped section 133 is the gap 134. The limiting piece 131 has a groove 135. An upper fixing post 172 is arranged on the limiting piece 131. The blocking piece 132 is arranged in the groove 135 and can move up and down in the groove 135. The lower end 174 of the blocking piece 132 extends out of the groove 135. A lower fixing post 173 is arranged at the lower end 174 of the blocking piece 132. When the blocking piece 132 moves up and down, the size of the gap 134 can be adjusted. An elastic device is arranged on the limiting piece 131. The elastic device has an elastic force, and this elastic force acts on the blocking piece 132 to make the gap 134 tend to decrease. In the example shown in the figure, the elastic device is a tension spring 136. The upper end of the tension spring 136 is fixedly connected to the upper fixing post 172 of the limiting piece 131, and the lower end of the tension spring 136 is connected to the lower fixing post 173 of the blocking piece 132. The elastic force of the tension spring 136 can pull the blocking piece 132 upward to reduce the gap 134. When an object is located in the gap 134, the limiting piece 131 and the blocking piece 132 clamp the object. The size of the gap 134 is adjustable so that it can adapt to objects of various sizes. The limiting piece 131 and the first stopper 143 are fixedly connected through a mounting bracket 171. When the first stopper 143 moves, it drives the limiting piece 131 to move through a transmission mechanism 120. In the Figure 1 example shown, there are two limiting pieces 131. Each limiting piece 131 is connected to a rack 122. One of the first stoppers 143 abuts against the other end 1422 of the connecting spring 142.

[0048] The following takes the pushing device 100 in the present invention for processing wires as an example for illustration. After the exposed conductors 201 of two bundles of wires 200 are connected, a section of insulating heat-shrinkable sleeve 210 is sleeved on the wires 200. The wires 200 are passed through the gap 134, and the limiting piece 131 and the blocking piece 132 clamp the wires 200. The insulating heat-shrinkable sleeve 210 is located between the two pushing members 130 and can move relative to the wires 200. The insulating heat-shrinkable sleeve 210 cannot pass through the gap 134. Therefore, when the pushing members 130 move, they can push the insulating heat-shrinkable sleeve 210 to move. The connecting spring 142 is in a pre-compressed state and has elastic force. The driving device 110 is started, and the driving device 110 pushes the push rod 141 to move. The push rod 141 drives the flange 144 to move. When the flange 144 moves away from the second stop block 161, the connecting spring 142 is further compressed. The elastic force generated when the connecting spring 142 is pre-compressed and the elastic force generated by the further compression by the flange 144 drive the first stop block 143 and the second stop block 161 to move. The connecting spring 142 transmits the driving force to the first stop block 143 and pushes the first stop block 143 to move. The first stop block 143 drives one of the racks 122 to move and then drives the gear 121 to rotate. The rotation of the gear 121 drives the other rack 122 to move. The moving directions of the two racks 122 are opposite, so the two limiting pieces 122 can move towards each other or away from each other, that is, move closer to or away from each other. When the two limiting pieces 131 move closer, they push the insulating heat-shrinkable sleeve 210 to move until Figure 7 as shown in the figure, the insulating heat-shrinkable sleeve 210 is pushed to the preset position. At this time, when the distance between the two limiting pieces 131 is equal to the length of the insulating heat-shrinkable sleeve 210, that is, the two limiting pieces 131 just abut against both ends of the insulating heat-shrinkable sleeve 210. When the two limiting pieces 131 continue to move closer, they are resisted by the insulating heat-shrinkable sleeve 210, and this resistance is transmitted to the first stop block 143 through the limiting piece 131. When this resistance is greater than the driving force of the driving device, the connecting spring 142 is compressed, and the push rod 141 moves relative to the connecting spring 142. The end of the push rod 141 passes through the first stop block 143 and then enters the detection range of the push rod position detection device 145, and the push rod position detection device 145 outputs a control signal. The upper computer judges according to the control signal that the push rod 141 has moved to the critical position and is not suitable for continuing to move. Therefore, the driving device 110 is controlled to stop working or output a reverse driving force to make the push rod 141 move in the reverse direction. After the insulating heat-shrinkable sleeve 210 moves to the preset position, the driving device 110 drives the limiting piece 131 to move in the reverse direction to be away from the insulating heat-shrinkable sleeve 210, facilitating subsequent process processing.

[0049] After the insulating heat shrinkable tube 210 is pushed to a preset position, the two push members 130 move away from each other and reset. During the reset, the driving device 110 generates a reverse driving force to drive the push rod 141 to move in the reverse direction. When the flange 144 moves in the reverse direction and contacts the second bump 161, it pushes the second stop 161 to move in the reverse direction, and then drives the first stop 143 and the rack 122 to move in the reverse direction through the connecting member 162, and then drives the other rack 122 to move through the gear 121, and finally the two push members 130 move away from each other to reset, so that the insulating heat shrinkable tube 210 of the next wire to be processed can be placed between the two push members 130. During this process, the connecting spring 142 elongates. During the reset process, even if the driving device 110 does not generate a reverse driving force, the elastic force after the connecting spring 142 is compressed causes the flange 144 and the push rod 141 to move in the reverse direction, and then pushes the second stop 161 to move in the reverse direction until it resets.

[0050] According to the technical solution of the present invention, one of the two push members can be set to be movable and the other to be fixed; the movable push member moves closer to or away from the other push member to push the insulating heat shrinkable sleeve 210 to a preset position.

[0051] The pushing device 100 in the present invention can be combined with a wire processing device (not shown in the figure) to form a wire processing equipment for splicing and connecting two bundles of wires 200. During processing, the pushing device 100 is used to transfer the insulating heat shrinkable tube 210 to a preset position, and then the wire processing device performs the next processing operation.

[0052] The present invention also provides a method for processing wires, which includes:

[0053] Placing the wire to be processed at the position to be processed, the wire to be processed includes a splicing part, and the splicing part is the connection part of the exposed conductors of two bundles of wires;

[0054] Transferring the insulating heat shrinkable tube to the splicing part of the wire to be processed so that the insulating heat shrinkable tube covers the splicing part;

[0055] When the insulating heat shrinkable tube is transferred to the splicing part of the wire to be processed, stop the transfer;

[0056] Heating the insulating heat shrinkable tube so that the insulating heat shrinkable tube shrinks and covers the splicing part of the wire to be processed.

[0057] The pushing device, wire processing equipment and wire processing method in the present invention. The driving device drives the pushing member to move through the transmission mechanism. When the pushing member moves, it pushes the insulating heat shrinkable sleeve to a preset position to facilitate the next processing operation. There are two pushing members, and at least one of the two pushing members is movable. When moving, it can push the insulating heat shrinkable sleeve to the preset position. The driving device is flexibly connected to the transmission mechanism, which can not only transmit the driving force to the transmission mechanism, but also stop driving the transmission mechanism when the pushing member pushes the pushed member to the preset position, avoiding damage to the pushed member caused by continuous output of the driving force. When the two pushing members are linked, they can push the insulating heat shrinkable sleeve from both sides of the insulating heat shrinkable sleeve, and the movement of the pushing member is smoother and more convenient to use. One gear meshes with two racks, which can realize the simultaneous opposite movement or opposite movement of the two pushing members, with a simple structure and convenient use. The flexible connection device adopts a push rod and a connecting spring, which can not only play a buffering role when driving the pushing member to move; but also make the push rod and the connecting spring move relative to each other when the pushing member moves in place, so as to collect control signals to know that the pushed member has moved in place. The push rod can support the connecting spring to keep it stable when transmitting the driving force. The use of the first stop block has a simple structure. The use of the first stop block and the second stop block can pre-compress the connecting spring to have a certain elastic force, and the elastic force of the connecting spring can be used to push the first stop block when the driving device is started, reducing the hysteresis of the driving force transmitted to the first stop block.. The position of the push rod can be known by using the push rod position sensor. When the push rod moves to the critical position, a control signal is output. According to the control signal, it can be known that the push rod has moved to the critical position, and then the driving device can be controlled to stop working or drive the push rod to move in the reverse direction. The gap size between the retaining piece and the limiting piece can be adjusted, and the present invention is applicable to wires, wire bundles and heat shrinkable sleeves of various diameters. The use of an elastic device helps the retaining piece and the limiting piece to clamp the wire, which can not only keep the wire stable during the centering process, but also ensure that the insulating heat shrinkable sleeve will be pushed to the preset position.

[0058] The above are only preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are all covered by the claims of the present invention.
