Description

Technical Field

[0001] The invention relates to automatic bundling equipment, and in particular to an automatic bundling equipment and method for a cable tie. Background Art

[0002] The present invention cites the applicant's published Chinese patents CN221738227U and CN220640344U as reference documents.

[0003] In the prior art CN220640344U, the inventor proposed an automatic harness bundling device, which disclosed structures such as a bundling assembly and a clip storage member, wherein the bundling assembly includes a first guide groove, a second guide groove, a tensioning member and a cutting member, wherein the first guide groove and the second guide groove can automatically bend the cable tie and guide the cable tie to pass through its square hole, the tensioning member can tighten the tail of the cable tie to achieve the tightening of the cable tie, and the cutting member can cut off the tail of the cable tie. The clip storage member stores a plurality of cable ties, and by storing the cable ties through the clip storage member, a plurality of cable ties can be transported to the bundling process at one time. A specific structure of a clip storage piece that can be used in the automatic wiring harness bundling device is shown in CN221738227U. The clip storage piece in this scheme includes a transversely extending storage slot, and the cable ties are fed into the storage slot one by one with their side edges in the width direction aligned with the storage slot. The storage slot can limit and fix the cable ties in the thickness direction of the cable ties. The clip storage piece of this structure has a very stable limiting and holding effect on the cable ties, but there is also a defect, that is, the cable ties stored in the clip storage piece cannot be directly applied to the wiring harness. For bundling operations, the cable ties are taken out from the magazine storage piece one by one and then transferred to the bundling position for automated bundling (see paragraphs 0046-0048 of the CN220640344U specification). Therefore, in the bundling process operation of CN220640344U, a first transfer piece is required to transfer the cable ties from the magazine storage piece to the bundling station, and a cable tie holder is required to be provided at the bundling station to position and hold the cable ties at the bundling station, and each cable tie needs to go through these processes. In general, the process of "taking the cable ties out of the magazine one by one - transporting and positioning the cable ties - bundling the cable ties" in the prior art increases the steps of automated operations, which is not conducive to further improving the operating efficiency, and the structure of the automatic bundling equipment is more complicated. Summary of the invention

[0004] In view of the above problems, the present invention provides a more optimized automatic bundling device for cable ties, and provides a more optimized automatic bundling method for cable ties.

[0012] Preferably, the disengagement mechanism comprises a toggle member disposed at the bundling station, and the toggle member is configured to be movable in a direction opposite to the direction in which the cable tie is loaded into the cable tie storage slot, so as to pull the cable tie out of the insertion port.

[0013] Preferably, the cable tie positioning platform comprises a second making way portion for making way for the disengagement mechanism, and the second making way portion is arranged on the cable tie storage slot at a position on the back side of the insertion port.

[0016] Preferably, it also includes a bundled piece, which can be relatively close to or away from the cable tie positioning platform to switch between a to-be-bundled position relatively close to the cable tie positioning platform and a standby position relatively away from the cable tie positioning platform. The bundled piece in the to-be-bundled position is close to one side of the bending and bundling direction of the cable tie on the cable tie positioning platform and is suspended above the cable tie positioning platform.

[0038] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0039] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0040] Embodiment 1:

[0041] See also Figure 1 As shown, as a preferred embodiment of the present invention, an automatic bundling device for cable ties is provided, comprising a base 1, on which a bundling station 20 is provided, on which a bundling execution device is provided, and the bundling execution device is used to realize automatic bundling of cable ties at the bundling station. Figure 2 The structure of a commonly used cable tie 100 is shown. The cable tie 100 includes a head 101 and a strap body 102. The head 101 is provided with a through hole 103. The through hole 103 allows the tail of the strap body 102 to be passed through and fixed in the through hole in a winding and bending manner. The cable tie 100 is a common cable tie. It is only used as an exemplary description of this embodiment. It can be understood that any cable tie in the prior art can be applied to this embodiment. The strapping execution device of this embodiment is implemented by the prior art. The strapping execution device includes a cable tie bending portion 21, a cable tie passing guide portion 22, a tensioning mechanism 23 and a cutting mechanism 24. The cable tie bending portion 21 is used to realize the bending of the strap body 102 toward the head 101. The cable tie passing guide portion 22 is used to guide the tail of the strap body 102 to pass through the through hole 103 of the head 101. The tensioning mechanism 23 is used to tighten the tail of the cable tie that has passed through the through hole 103. The cutting mechanism 24 is used to cut the tail of the cable tie. For more details about the strapping execution device, please refer to the applicant's patent CN220640344U, which will not be repeated in this example.

[0042] The base 1 is also provided with a cable tie positioning platform 3 and a mobile driver (not shown due to angle reasons). The cable tie positioning platform 3 includes a plurality of cable tie storage slots 30 arranged at intervals. The cable tie storage slots 30 are used to position and place a single cable tie 100, and the cable tie storage slots 30 are configured to allow the cable tie 100 loaded therein to be bent and tied directly without leaving the cable tie storage slots 30. The mobile driver is drivingly connected to the cable tie positioning platform 3, and is used to drive the cable tie positioning platform 3 to move back and forth along the arrangement direction of the cable tie storage slots 30. The bundling station 20 is set on the moving path of the cable tie positioning platform 3, so that the mobile driver can drive the cable tie positioning platform 3 to approach or move away from the bundling station 20, so as to transfer the cable ties 100 on the cable tie positioning platform 3 to the bundling station 20 one by one. The mobile driver can be implemented by any driving device, such as a motor, a cylinder, an oil cylinder, etc., as long as it can eventually drive the cable tie positioning platform 3 to move. It is understandable that after each tie 100 on the tie positioning platform 3 reaches the bundling station 20, the tie positioning platform 3 can be controlled to stop moving by electrical control technology. For example, a sensor (such as a photoelectric sensor) for detecting the tie 100 is set at the bundling station 20. Once the sensor detects the tie 100, a signal is sent to cause the controller to control the mobile driver to pause, so that the tie positioning platform 3 can achieve step-by-step movement toward the bundling station 20. When the tie 100 is paused at the bundling station 20, the bundling execution device is started to automatically bundle the tie 100.

[0043] In this embodiment, the thickness direction of a single cable tie 100 loaded into the cable tie storage slot 30 is defined as the thickness direction of the cable tie storage slot 30, and one side of the cable tie storage slot 30 in the thickness direction is set as an open insertion port, and the open insertion port allows the cable tie 100 to be directly inserted into the cable tie storage slot 30 from its thickness direction. Specifically in this embodiment, the side of the cable tie storage slot 30 close to the base 1 has a physical structure supporting the cable tie 100, and the side of the cable tie storage slot 30 away from the base 1 is set as an open insertion port. It can be understood that the thickness direction of the cable tie 100 is also the bending and bundling direction of the cable tie 100, because one side of the cable tie storage slot 30 in the thickness direction is completely open, so the cable tie 100 remaining in the cable tie storage slot 30 can also be directly bent and bundled. In other words, under such a configuration, the cable tie 100 remaining in the cable tie storage slot 30 still has space for direct bending and bundling, so that the cable tie storage slot 30 allows the cable tie 100 loaded therein to be directly bent and bundled without leaving the cable tie storage slot 30. The shape of the cable tie storage slot 30 may have a portion adapted to the shape of the cable tie 100, especially at a position corresponding to the head 101 of the cable tie 100, the shape of the cable tie storage slot 30 is adapted to the shape of the head 101, so that the cable tie storage slot 30 can better position and hold the cable tie 100.

[0044] Figure 3The schematic diagram of the automatic bundling device of the cable tie in the bundling working state is shown, wherein a cable tie 100 at the frontmost side (that is, closest to the bundling station 20) on the cable tie positioning platform 3 is transported to the bundling station 20 under the driving of the mobile driver on the cable tie positioning platform 3, and a bundled object 200 is horizontally placed on the cable tie positioning platform 3 and is located on the side of the cable tie 100 on the cable tie positioning platform 3 in the bending and bundling direction. At this time, the bundling execution device is started, and the cable tie bending portion 21 bends the belt body 102 of the cable tie 100 so that the belt body 102 is bent and wound around the bundled object 200, and under the guidance of the cable tie threading guide portion 22, the belt body 102 passes through the threading hole 103, and the cable tie 100 is tightened under the action of the tensioning mechanism 23. After the cable tie 100 is tightened, the tail of the belt body 102 is cut off by the cutting mechanism 24, completing the tightening action of the cable tie 100. It can be seen that after the tightening operation of a cable tie 100 is completed, the cable tie 100 still remains in the cable tie storage slot 30, in order to perform subsequent cable tie bundling operations, such as Figure 4 , Figure 5In this embodiment, a disengagement mechanism 4 is further provided, and the disengagement mechanism 4 is configured to be able to exert force on the cable tie 100 in the cable tie storage slot 30 of the bundling station 20, so that the cable tie 100 after bundling is disengaged from the cable tie storage slot 30. In this embodiment, the disengagement mechanism 4 is specifically a lever driven by a cylinder, which is arranged at the back side of the open insertion port of the cable tie storage slot 30. After the cable tie 100 is bundled, the lever of the disengagement mechanism 4 moves in the opposite direction of the cable tie 100 being loaded into the cable tie storage slot 30, and the cable tie 10 is pulled out of the open insertion port of the cable tie storage slot 30. In other embodiments, the disengagement mechanism 4 may also be implemented by other structures. For example, the disengagement mechanism 4 may be a clamping claw, which clamps the cable tie 100 and takes the cable tie out of the cable tie storage slot 30 by moving. The disengagement mechanism 4 may also be a movable vacuum suction nozzle, which sucks the cable tie and takes the cable tie out of the cable tie storage slot 30 by moving. The position where the disengagement mechanism 4 applies force to the cable tie 100 may be the head 101 of the cable tie 100 or the body 102 of the cable tie 100. If the lever is used as the disengagement mechanism 4 in this embodiment, it is more appropriate for the disengagement mechanism 4 to apply force to the head 101 of the cable tie 100, and the force application effect is better. If a vacuum suction nozzle or a clamping claw is used as the disengagement mechanism 4, the disengagement mechanism 4 may also apply force to the body 102 of the cable tie 100. If a disengagement mechanism 4 with different structures is used, the setting position of the disengagement mechanism 4 may also be adaptively changed. If a vacuum suction nozzle or a clamping claw is used as the disengagement mechanism 4, the disengagement mechanism 4 may also be set on the side where the insertion port of the cable tie storage slot 30 is open. A person skilled in the art can select a reasonable disengagement mechanism 4 according to actual conditions, and adaptively change the installation position of the disengagement mechanism 4. Any disengagement mechanism 4 that can apply force to the cable tie 100 in the cable tie storage slot 30 of the bundling station 20 so that the bundled cable tie 100 is disengaged from the cable tie storage slot 30 is feasible.

[0045] After the previous cable tie 100 enters the bundling station 20 to complete bundling and is separated from the cable tie storage slot 30, the cable tie positioning platform 3 can continue to move so that the next cable tie 100 enters the bundling station 20, and the action is repeated until all cable ties 100 on the cable tie positioning platform 3 are tied to the bundled object 200. During the process that the previous cable tie 100 completes bundling and the next cable tie enters the bundling station 20, the relative position of the bundling station 20 and the bundled object 200 can be changed by moving the bundled object 200 or moving the entire automatic bundling equipment, so that the area on the bundled object 200 that is not tied by the cable tie is moved to the bundling station 20, and the next cable tie 100 then bundles the area on the bundled object 200 that is not tied by the cable tie. This can be easily achieved in the art through an automatic moving mechanism, for example, a driving device is provided to control the movement of the bundled piece 200 relative to the entire automatic bundling device, or a driving device is provided to control the movement of the entire automatic bundling device relative to the bundled piece 200. Because the strap 100 on the strap positioning platform 3 can be directly bundled, if the outer surface of the bundled piece 200 is relatively smooth, the bundled piece 200 can be directly mounted on the strap positioning platform 3. If the outer surface of the bundled piece 200 is relatively rough, such as the bundled piece 200 of the present embodiment is a corrugated tube, in order to avoid the bundled piece 200 affecting the movement of the strap positioning platform 3, a more preferred solution is that the bundled piece 200 is suspended above the strap positioning platform 3, for example, by additionally providing a bearing member / holder to place the bundled piece 200, and the bearing member / holder can also be used to drive the bundled piece 200 to move relative to the strap positioning platform 3.

[0046] With the automatic strapping device for cable ties of this embodiment, the movement of the cable tie positioning platform 3 can quickly transport the cable tie 100 to the strapping station 20, and the cable tie 100 can be directly strapped on the cable tie positioning platform 3. Therefore, compared with the solution of taking out the cable ties from the magazine storage one by one in the prior art, and then transferring and positioning the cable ties to the strapping station 20 for strapping, the automatic strapping device for cable ties of this embodiment eliminates the repeated action of taking and placing the cable ties back and forth during the transfer process one by one, and the cable ties 100 are positioned on the cable tie positioning platform 3, which also eliminates the action of re-positioning the cable ties after entering the strapping station in the prior art. The automatic strapping device for cable ties of this embodiment simplifies the steps of automated operations in the automatic strapping process, improves the operating efficiency, and simplifies the structure of the automatic strapping device.

[0047] It is understandable that the cable ties 100 can be loaded manually, that is, a worker installs the cable ties 100 one by one on the cable tie positioning platform 3, and after the cable ties 100 are full, the automatic bundling device is started to start automatic bundling.

[0048] In this embodiment, if Figure 6 The cable tie positioning platform 3 further includes a loading platform 31 and a cable tie storage clip 32 that can be unloaded and loaded on the loading platform 31. The cable tie storage slot 30 is arranged on the cable tie storage clip 32, and the mobile driver is drivingly connected to the loading platform 31. The cable tie storage clip 32 is used to store a plurality of cable ties 100. Then, the cable tie storage clip 32 can be loaded one by one into the cable tie storage clip 32 in cooperation with the automatic feeding mechanism, and then the cable tie storage clip 32 is loaded on the loading platform 31 for subsequent bundling. After the cable ties 100 on the cable tie storage clip 32 are used up, the cable tie storage clip 32 is unloaded to re-load the cable ties 100. The automatic feeding mechanism of the cable tie 100 can be realized by existing technologies such as a manipulator and a positioning fixture. Compared with the manual feeding method, the use of the cable tie storage clip 32 can improve the automation level of the automatic bundling equipment.

[0049] The specific structure of the cable tie storage clip 32 of this embodiment can be found in Figure 7-Figure 9 As shown, the cable tie storage magazine 32 includes a magazine base 321, and a cable tie storage slot 30 is provided on the magazine base 321 (in this embodiment, 5 cable tie storage slots 30 are provided, so 5 cable ties 100 can be stored at a time), and the shape of the cable tie storage slot 30 is suitable for a single cable tie 100 to be loaded therein, and the width direction, thickness direction and length direction of the single cable tie 100 loaded into the cable tie storage slot 30 are defined as the width direction, thickness direction and length direction of the cable tie storage slot 30, respectively, that is, Figure 7 and Fig. 9 In the figure: the X direction and its opposite direction are the width directions of the cable tie 100 and the cable tie storage slot 30 , the Y direction and its opposite direction are the thickness directions of the cable tie 100 and the cable tie storage slot 30 , and the Z direction and its opposite direction are the length directions of the cable tie 100 and the cable tie storage slot 30 .

[0050] One side of the cable tie storage slot 30 in the thickness direction is set as an open insertion port, or in other words, the cable tie storage slot 30 is open in the Y direction, so that the cable tie 100 can be directly inserted into the cable tie storage slot 30 from the thickness direction. It can be understood that the cable tie storage slot 30 has a slot bottom in the thickness direction, and the cable tie 100 is completely inserted into the cable tie storage slot 30 when it is inserted and touches the slot bottom. The cable tie storage clip 32 also includes a limiting portion 323, which is an elastic clip in the present embodiment, including two left and right opposite spring plates arranged on the left and right sides of the width direction of the cable tie storage slot 30, and the spring plates are bent into a V-shape. During the process of inserting the cable tie 100 into the cable tie storage slot 30, the cable tie 100 can pass over the tip of the V-shape under the guidance of the spring plates, so that the spring plates and the cable tie 100 form a limiting fit, and the spring plates limit the cable tie 100 from easily escaping from the thickness direction of the cable tie storage slot 30, thereby keeping the cable tie 100 in the cable tie storage slot 30, and the limiting of the cable tie 100 in other directions is achieved by the cable tie storage slot 30 cooperating with the shape of the cable tie 100.

[0051] The setting of the limiting portion 323 is not necessary. For example, if the cable tie 100 is always placed horizontally during the feeding process of the cable tie storage clip 32 or during the transportation process of the cable tie storage clip 32, that is, the Y direction is kept vertically upward, then the gravity of the cable tie 100 itself is sufficient to limit the cable tie 100 to be kept in the cable tie storage slot 30. The limiting portion 323 is provided in this embodiment. On the one hand, the cable tie 100 can be kept in the cable tie storage slot 30 more stably. On the other hand, even if the cable tie storage clip 32 is transported in a vertical posture (that is, the Y direction is kept horizontal), the cable tie 100 will not fall out of the cable tie storage clip 32, which is more convenient for the automatic transportation of the cable tie storage clip 32, and at the same time, the cable tie 100 can be fed to the cable tie storage clip 32 in a vertical posture. In short, the limiting portion 323 is provided to allow the cable tie 100 to be more stably maintained in the cable tie storage slot 30 , so that the posture of the cable tie storage clip 32 during the process of automatic loading and transportation is less restricted and more flexible.

[0052] In order to improve the stability of the limiting cooperation between the limiting portion 323 and the cable tie 100, the limiting portion 323 is arranged at the position corresponding to the head 101, that is, the limiting portion 323 and the head 101 are limited and cooperated. In other embodiments, the limiting portion 323 can also be arranged in the thickness direction of the cable tie storage slot 30 to directly stop the cable tie 100. However, the limiting portion 323 in this embodiment needs to be movable. In the automatic strapping equipment, it is also necessary to automatically control the movement of the limiting portion 323 to close or open the cable tie storage slot 30. Therefore, it is preferred to set the limiting portion 323 on the side in the width direction of the cable tie storage slot 30. The limiting portion 323 can of course also act on the body 102 of the cable tie 100, but the limiting cooperation between the limiting portion 323 and the head 101 of the cable tie 100 has higher stability. In addition to the spring structure specifically used in this embodiment, other structures can also be used to replace the limiting portion 323, such as Fig.10 A modified example of the position limiting part 323 of this embodiment is proposed. This modified example is formed by a V-shaped sliding block and a compression spring. Its effect is basically the same as that of the spring sheet of this embodiment. Alternatively, the position limiting part 323 can also be replaced by a ball-type elastic clip in CN221738227U (see CN221738227U). Figure 3and paragraph 0033 of the specification). Alternatively, if the elastic mechanism is not used to implement the limiting portion 323, a buckle mechanism can also be used to implement the limiting portion 323, such as the limiting portion 323 is a buckle set on the two side groove walls in the width direction of the cable tie storage slot 30, but with this solution, the disengagement mechanism 4 needs a large force to make the cable tie 100 escape. In short, as long as the limiting portion 323 can be limited and matched with the cable tie 100 loaded into the cable tie storage slot 30 to keep the cable tie 100 in the cable tie storage slot 30, and the limiting cooperation between the limiting portion 323 and the cable tie 100 is detachable, it is a feasible solution.

[0053] Continue reading Figure 7-Figure 9 , and refer to Fig.11 , Fig.11 The structure of the loading platform 31 is shown, with the insertion port of the cable tie storage slot 30 opened at the first side of the cable tie storage slot 30, and the other side away from the first side is the second side of the cable tie storage slot 30, corresponding to Figure 7 and Fig. 9 That is, one side of the cable tie storage slot 30 in the Y direction is the first side, and the other side of the cable tie storage slot 30 in the opposite direction of the Y direction is the second side. A first clearance opening 325 is provided on the second side of the cable tie storage slot 30, and a second clearance opening 315 is provided on the loading platform 31 at a position corresponding to the first clearance opening 325. The first clearance opening 325 and the second clearance opening 315 correspond to the positions of the through-hole 103 of the cable tie 100. The first clearance opening 325 and the second clearance opening 315 together form a first clearance portion for allowing the strap body 102 of the cable tie 100 in the cable tie storage slot 30 to continue to pass through its through-hole 103. Furthermore, a third yielding opening 324 is provided on the second side of the cable tie storage slot 30, and a fourth yielding opening 314 is provided on the loading platform 31 at a position corresponding to the third yielding opening 324. The third yielding opening 324 and the fourth yielding opening 314 together form a second yielding portion for yielding the disengagement mechanism 4. In this embodiment, the second yielding portion corresponds to the position of the head 101 of the cable tie 100 loaded into the cable tie storage slot 30. If the disengagement mechanism 4 in the form of a lever in this embodiment is not adopted, the form of the second yielding portion for yielding the disengagement mechanism 4 on the cable tie positioning platform 3 can be adaptively changed.

[0054] Continue reading Figure 7In this embodiment, the clip base 321 further includes a head accommodating portion 3211 and a body supporting portion 3212. The head accommodating portion 3211 is correspondingly arranged at the position of the head 101 of the cable tie 100, and the body supporting portion 3212 is correspondingly arranged at the position of the body 102 of the cable tie 100 and extends along the length direction of the cable tie 100. The cable tie storage slot 30 includes a head insertion slot 301 arranged on the head accommodating portion 3211 and a body insertion slot 302 arranged on the body supporting portion 3212. It is understandable that the belt body supporting portion 3212 is not necessary. If the clip base 321 in other embodiments only includes the head accommodating portion 3211, the cable tie storage slot 30 is the head insertion slot 301. In this case, the limiting portion 323 and the head insertion slot 301 cooperate to ensure that the cable tie 100 is stably loaded into the head insertion slot 301. The provision of an additional belt body supporting portion 3212 can, on the one hand, limit the belt body 102 from sagging, ensure the position accuracy of the belt body 102, and thus improve the success rate of automatic bundling. On the other hand, the belt body supporting portion 3212 can also form a bearing / limiting platform for the bundled object 200. The belt body supporting portion 3212 in this embodiment is a plate-like structure, and of course the belt body supporting portion 3212 can also be a hollow frame structure. A stop boss 326 is provided at one end of the belt body supporting portion 3212 away from the head accommodating portion 3211 , and a receiving area for the bundled piece 200 is formed between the stop boss 326 and the head accommodating portion 3211 . This arrangement can better position the bundled piece 200 .

[0055] Compared with the prior art CN221738227U, the cable tie storage clip 32 of the present embodiment is more conducive to the loading / refilling of the cable tie 100 into the cable tie storage slot 30, because when loading the cable tie 100, the cable tie 100 only needs to be aligned with the cable tie storage slot 30 one by one and inserted, and there is no need to push the cable ties 100 into a common storage slot one by one and use the latter cable tie to push the previous cable tie into a deeper position. Therefore, loading the cable tie 100 into the cable tie storage slot 30 is more labor-saving and simple.

[0056] For loading and unloading of the cable tie storage clip 32 on the loading platform 31, it is feasible to use any unloadable connection method to position and connect the cable tie storage clip 32 and the loading platform 31, for example, a clamp seat is provided on the loading platform 31, and the cable tie storage clip 32 is clamped on the loading platform 31, and for another example, a magnetic suction component is provided on the loading platform 31 and the cable tie storage clip 32, and the cable tie storage clip 32 is loaded by magnetic suction. The cable tie storage clip 32 can be transferred by a grasping device such as a manipulator. In addition, in order to prevent the bundled parts 200 from affecting the loading and unloading of the cable tie storage clip 32 on the loading platform 31, the bundled parts 200 can be controlled by an automatic moving mechanism to be relatively close to or away from the cable tie positioning platform 3, so that the bundled parts 200 can be switched between a to-be-bundled position relatively close to the cable tie positioning platform 3 and a standby position relatively away from the cable tie positioning platform 3. When the bundled parts 200 are in the standby position, the cable tie storage clip 32 is loaded and unloaded on the loading platform 31.

[0057] Because the cable tie storage clip 32 can be unloaded, different types of cable tie storage clips 32 can be replaced in actual production to store different types of cable ties, which is convenient for bundling different types of cable ties. In addition, the cable tie bending portion 21 and the cable tie threading guide portion 22 can also be designed as a modularly replaceable structure to adapt to different types of cable ties.

[0058] In this embodiment, the bundled member 200 is a corrugated tube, such as Figure 3 As shown, in order to improve the accuracy of the bundling position of the cable tie 100 on the bundled piece 200, a reflective photoelectric sensor 5 is further provided on the base 1. The reflective photoelectric sensor 5 emits a laser to the bundled piece 200. According to the reflected signal received by the reflective photoelectric sensor 5, it can be determined whether the position of the bundled piece 200 at the bundling station 20 is a crest or a trough, thereby realizing the detection of the bundled position of the bundled piece 200, so that the cable tie 100 can be accurately bundled at the trough position of the bundled piece 200.
