Description

Technical Field

[0001] The utility model relates to the technical field of cable processing equipment, in particular to a plastic shell inserting equipment. Background Art

[0002] In the field of automotive wiring harnesses, cables with plastic shells can protect cable terminals. When manufacturing such wiring harnesses, they are usually required to go through stripping, terminal crimping and plastic shell insertion operations first; the plastic shell insertion inserts the end of the wire harness with the terminal crimped into the plastic shell. How to improve the accuracy and efficiency of the plastic shell insertion has become a problem that needs to be solved urgently.

[0003] In the prior art, the automatic insertion of the plastic shell mostly includes two parts: plastic shell loading and wire harness plugging. The plastic shell is moved in the direction of the wire harness plugging, and then the wire harness is clamped and moved in the direction of the plastic shell until it is inserted into the plastic shell. In order to further improve the accuracy of inserting the plastic shell, the prior art often sets a flared guide hole at the front end of the plastic shell so that the wire harness can enter the interior of the plastic shell along the guide hole.

[0004] However, due to the certain weight of the outer conductor at the end of the plastic shell, the conductor at the end of the cable is prone to bend downward when the wire diameter is small or the wire harness is relatively soft, thereby reducing the success rate of inserting the shell. Utility Model Content

[0005] In view of at least one of the above technical problems, the utility model provides a plastic shell inserting device, which adopts structural improvement to improve the accuracy of shell insertion.

[0006] According to a first aspect of the utility model, there is provided a plastic shell inserting device, comprising:

[0007] A clamping mechanism, wherein the clamping mechanism comprises a first clamping member for clamping a wiring harness body and a second clamping member for clamping a wiring harness terminal, wherein the clamping centers of the first clamping member and the second clamping member are arranged in a colinear manner; the clamping mechanism moves toward the direction of the socket of the plastic shell body under the drive of an external force, and stops after being inserted into the plastic shell; the second clamping member is configured to maintain clamping of the terminal before the terminal is inserted into the plastic shell body, and to release the clamping of the terminal body and move the terminal out of the shell penetration range when the end of the terminal is inserted into the plastic shell body; the first clamping member is configured to maintain clamping of the wiring harness body until the terminal is completely inserted into the plastic shell body.

[0008] Furthermore, the clamping mechanism is provided with a lifting drive mechanism, and the lifting drive mechanism is connected to the second clamping member and is used to drive the lifting of the second clamping member.

[0009] Furthermore, the clamping mechanism also has a pressure sensor with one end fixedly connected to the first clamping member and the other end fixedly connected to the first clamping member, for detecting whether the shell is inserted into place.

[0010] Furthermore, it also includes a driving mechanism, which includes a bracket, a lateral driving assembly arranged on the bracket, and a feed driving assembly connected to the lateral driving assembly. The clamping mechanism is connected to the feed driving assembly and is used to drive the wiring harness to move in a direction close to or away from the plastic shell body.

[0011] Furthermore, the feed drive assembly is also connected to a vertical drive assembly, and the clamping mechanism is fixed on the drive end of the vertical drive assembly.

[0012] Furthermore, it also includes a mold shell transmission device, which is arranged opposite to the bracket, and the mold shell transmission device has a mold shell positioning seat arranged toward the bracket.

[0013] Furthermore, the bottom of the plastic shell transmission device has a roller and a wheel locking mechanism.

[0014] Furthermore, the plastic shell positioning seat also has a buckle assembly for engaging the buckle on the plastic shell.

[0015] The beneficial effects of the utility model are as follows: the utility model arranges the first clamping piece and the second clamping piece on the clamping mechanism so that when the clamping mechanism is passed toward the plastic shell, the second clamping piece that clamps the terminal is in line with the first clamping piece that clamps the wiring harness body, which can ensure the straightness of the wiring harness before insertion and avoid skewing of the terminal. After the terminal is inserted into the plastic shell, the second clamping piece opens and moves away without affecting the continued insertion of the terminal. Compared with the prior art, there is no need to set a guide port, and the accuracy and reliability of insertion are also improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] like Figures 1 to 6 The plastic shell inserting device shown includes a clamping mechanism 1, specifically as follows Figure 1 and Figure 2As shown in the figure, the clamping mechanism 1 has a first clamping member 11 for clamping the wiring harness body 02 and a second clamping member 12 for clamping the wiring harness terminal 02a, and the clamping centers of the first clamping member 11 and the second clamping member 12 are arranged in a colinear manner; the clamping mechanism 1 moves toward the direction of the socket of the plastic shell body 01 under the drive of external force, and stops after being inserted into the plastic shell; the second clamping member 12 is configured to maintain the clamping of the terminal 02a before the terminal 02a is inserted into the plastic shell body 01, and release the clamping of the terminal 02a body and move the terminal 02a away from the shell when the end of the terminal 02a is inserted into the plastic shell body 01; the first clamping member 11 is configured to maintain the clamping of the wiring harness body 02 until the terminal 02a is completely inserted into the plastic shell body 01. It should be pointed out here that there are many ways to open the shell penetration range of the second clamping member 12 to open the terminal 02a, such as opening the two claws of the second clamping member 12 to not affect the continued penetration of the first clamping member 11, or opening the claws of the second clamping member 12 and moving it in a direction away from the wiring harness body 02.

[0027] In the above embodiment, by arranging the first clamping member 11 and the second clamping member 12 on the clamping mechanism 1, when the clamping mechanism 1 is inserted toward the plastic shell, the second clamping member 12 clamping the terminal 02a is in line with the first clamping member 11 clamping the wiring harness body 02, which can ensure the straightness of the wiring harness before insertion and avoid the skewness of the terminal 02a. After the terminal 02a is inserted into the plastic shell, the second clamping member 12 opens and moves away without affecting the continued insertion of the terminal 02a. Compared with the prior art, there is no need to set a guide port, and the accuracy and reliability of insertion are also improved.

[0028] Based on the above examples, please continue to refer to Figure 1 and Figure 2 In some embodiments of the utility model, the clamping mechanism 1 is provided with a lifting drive mechanism 2, which is connected to the second clamping member 12 and is used to drive the lifting of the second clamping member 12. Specifically, a supporting structure for fixing the first clamping member 11 and the second clamping member 12 can be provided, and the lifting drive mechanism 2 is fixed on the supporting structure and is used to drive the lifting of the second clamping member 12. Of course, it should be pointed out here that there are many specific lifting drive structures, such as the structural form of the motor screw nut seat, or the motor drives the synchronous wheel to drive the rotation of the synchronous belt, or the motor drives the gear to drive the rotation of the rack, etc., and technicians in this field can set it according to needs.

[0029] Optionally, in an embodiment of the present utility model, a structure for detecting whether the wiring harness is inserted in place is also provided, such as Figure 2As shown in the figure, the clamping mechanism 1 also has a pressure sensor 14 fixed at one end and fixedly connected to the first clamping member 11 at the other end, which is used to detect whether the shell is inserted into place. During the process of inserting the plastic shell, after the plastic shell is inserted into place, the terminal 02a will be stuck inside the plastic shell. Through the setting of the pressure sensor 14, the clamping mechanism 1 can be driven to clamp the wire harness and move in the direction away from the plastic shell. If the pressure increases within a reasonable range, it means that the buckle is in place. If the pressure increases first and then suddenly decreases, it means that the buckle is not in place and needs to be reinserted.

[0030] In some embodiments of the present invention, Figure 3 As shown in , it also includes a driving mechanism 2, which includes a bracket 21, a lateral driving component 22 arranged on the bracket 21, and a feed driving component 23 connected to the lateral driving component 22. The clamping mechanism 1 is connected to the feed driving component 23 to drive the wire harness to move toward or away from the plastic shell body 01. Through the setting of the driving mechanism 2, the wire harness can be clamped and transferred from other stations. The feed driving component 23 here is the external force that drives the clamping mechanism 1 to move as mentioned above; both the lateral drive and the feed drive are linear moving structures. The linear moving structure is a prior art and has been mentioned above, so it will not be repeated here.

[0031] In addition, in some embodiments of the present invention, in order to further improve the adaptability of the device, please continue to refer to Figure 3 The feed drive assembly 23 is also connected to a vertical drive assembly 24, and the clamping mechanism 1 is fixed to the driving end of the vertical drive assembly 24. By setting the vertical drive assembly 24, it can adapt to the clamping requirements of workstations of different heights.

[0032] In some embodiments of the present invention, Figures 4 to 6 As shown in the figure, it also includes a plastic shell transmission device 3, which is arranged opposite to the bracket 21. The plastic shell transmission device 3 has a plastic shell positioning seat 31 arranged toward the bracket 21. It should be pointed out here that the transmission of the plastic shell has a variety of structural forms, for example, it can be clamped and placed by a mechanical arm, or it can be transported by the vibration of a vibration plate. The loading of the plastic shell is a prior art and will not be repeated here.

[0033] Alternatively, if Figure 5As shown in , the bottom of the plastic shell transmission device 3 has a roller 32 and a wheel locking mechanism 33. The wheel locking mechanism 33 here also has various forms, for example, it can be a card plate that is stuck on the roller 32 to prevent the roller 32 from moving, or it can be a Forma wheel, that is, by rotating the base so that the base contacts the ground, so that the roller 32 cannot continue to move. Through the setting of this structural form, the flexibility of the plastic shell insertion device can be further improved. For example, when it is necessary to insert plastic shells of different specifications, the roller 32 can be directly moved to the set position by replacing a plastic shell transmission device 3. After the roller 32 is locked, the plastic shell insertion operation of another type of plastic shell can continue, thereby improving the convenience of use.

[0034] Optionally, in some embodiments of the present invention, Figure 6 As shown in the figure, the molded case positioning seat 31 also has a buckle assembly 34 for engaging the buckle on the molded case. The buckle assembly 34 is used to press down the buckle on the molded case in a raised state so that the buckle engages with the buckle groove on the terminal 02a, thereby achieving the buckle of the terminal 02a and the molded case body 01. It should be pointed out here that there are many specific structures of the buckle assembly 34, for example, it can be implemented by a cylinder or a hydraulic cylinder, and those skilled in the art can choose according to needs.

[0035] Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description are only for explaining the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which are within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
