DETAILED DESCRIPTION

[0042] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0043] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0044] Combination Figure 1 and Figure 2 As shown, the embodiment of the present disclosure provides an external auxiliary positioning member cutting device, which includes an extrusion member 1 and a pressure member 2; the extrusion member 1 can be driven reciprocatingly along the clamping direction; the pressure member 2 is arranged opposite to the extrusion member 1 along the clamping direction, and is provided with a receiving portion 21 for accommodating a workpiece 3, and a cutting through hole 22 located outside the receiving portion 21 and capable of accommodating the external auxiliary positioning member; wherein; a cutting head 23 is provided on the side of the cutting through hole 22 facing away from the extrusion member 1; the extrusion member 1 can extrude the workpiece 3 in the receiving portion 21 to move toward the cutting head 23, so that the cutting head 23 cuts the external auxiliary positioning member.

[0045] The external auxiliary positioning member cutting device provided in the embodiment of the present disclosure can be specifically but not limited to being applied to the cutting of external auxiliary positioning members in the narrow frame baffle of a liquid crystal display screen, and this is taken as an example for explanation of its use.

[0046] When the external auxiliary positioning piece cutting device is used, the workpiece 3 (specifically, the narrow frame baffle of the liquid crystal display) is first placed in the corresponding receiving portion 21 in the pressure-bearing piece 2, and the external auxiliary positioning piece in the workpiece 3 is placed in the corresponding cutting hole 22 outside the receiving portion 21. Then, the extrusion piece 1 is driven to move toward the pressure-bearing piece 2 along the clamping direction, and the workpiece 3 in the receiving portion 21 is squeezed to move toward the cutting head 23, so that the cutting head 23 is relatively facing the external auxiliary positioning piece, and until the external auxiliary positioning piece is cut and falls off, finally the extrusion piece 1 moves in the opposite direction away from the pressure-bearing piece 2 to the initial position, and the one-time cutting process of the external auxiliary positioning piece is completed.

[0047] Compared with the method of manually removing external auxiliary positioning parts in the prior art, the external auxiliary positioning part cutting device provided in the embodiment of the present disclosure can simultaneously perform top cutting on multiple external auxiliary positioning parts in the workpiece 3 through the cutting head 23 in one cutting process, which has the beneficial effects of high cutting efficiency, no residual burrs on the external auxiliary positioning parts, and no influence on the gluing fixing strength of the workpiece 3.

[0048] In one embodiment, the pressure-bearing part 2 also includes a movable plate 24 and a fixed plate 25; the accommodating portion 21 and the cutting through hole 22 are respectively opened on the movable plate 24; the fixed plate 25 is arranged at intervals on the side of the movable plate 24 facing away from the extrusion part 1, and is supported and connected to the movable plate 24 through a telescopic part 26; wherein the cutting head 23 is arranged on the fixed plate 25, and the cutting edge is facing the cutting through hole 22.

[0049] Specific, combined Figure 2 To further explain in detail, the pressure-bearing member 2 is specifically configured as a fixed plate 25 and a movable plate 24 arranged above the fixed plate 25, and the two are elastically and movably connected by a telescopic member 26. In this way, when the extrusion member 1 moves toward the pressure-bearing member 2 along the clamping direction, the movable plate 24 will first move toward the fixed plate 25 under the extrusion action of the extrusion member 1, and further squeeze the telescopic member 26. The workpiece 3 placed corresponding to the accommodating portion 21 in the movable plate 24 and the external auxiliary positioning member placed corresponding to the cutting hole 22 can synchronously move toward the cutting head 23 in the fixed plate 25, and when the cutting edge in the cutting head 23 relatively penetrates into the cutting hole 22 to a certain depth, the external auxiliary positioning members in the cutting hole 22 can be cut.

[0050] Furthermore, when the extruding member 1 moves in the reverse direction, the telescopic member 26 can be extended and reset accordingly, so that the movable plate 24 can be reset.

[0051] The specific arrangement of the pressure-bearing member 2 has the beneficial effects of simple structure, being able to timely cut the external auxiliary positioning member when the extrusion member 1 is extruded, and timely resetting the movable plate 24 when the extrusion member 1 is reset.

[0052] In one embodiment, a discharge hole 251 corresponding to the cutting hole 22 is further provided in the fixing plate 25 ; the discharge hole 251 is used to discharge the external auxiliary positioning piece that falls out of the cutting hole 22 after cutting.

[0053] Specific, combined Figure 2To further explain in detail, a discharge hole 251 corresponding to the cutting hole 22 is also opened in the fixed plate 25. The discharge hole 251 can be specifically arranged to correspond to the cutting hole 22 one by one, and the discharge hole 251 can also be arranged to have a large upper opening and a small inner opening, so that the discharge hole 251 can better receive the external auxiliary positioning piece cut and dropped in the cutting hole 22, so as to collect and reuse the waste.

[0054] In one embodiment, an elastic extrusion head 11 corresponding to the receiving portion 21 is further provided on a side of the extrusion member 1 facing the movable plate 24 .

[0055] Specific, combined Figure 2 To further explain in detail, an elastic extrusion head 11 corresponding to the accommodating portion 21 is also provided on the side of the extrusion member 1 facing the movable plate 24. The elastic extrusion head 11 can be specifically but not limited to a strip shape, a frame shape, a scroll shape, etc. The material of the elastic extrusion head 11 is specifically but not limited to elastic and soft silicone, rubber, etc., so that when the extrusion member 1 moves toward the movable plate 24 for extrusion, the elastic extrusion head 11 will act as a buffer contact member between the two, which can not only transmit the extrusion stress to the movable plate 24, but also avoid the problem of accidental extrusion damage of the workpiece 3 in the movable plate 24 caused by a sudden increase in the extrusion stress.

[0056] In one embodiment, the telescopic member 26 includes a telescopic rod and a compression spring sleeved on the outside of the telescopic rod; both ends of the compression spring are respectively supported and abutted against the movable plate 24 and the fixed plate 25, and when the telescopic rod contracts along its own axis, the compression spring further contracts.

[0057] Specific, combined Figure 2 To further explain in detail, the telescopic member 26 is specifically configured as a telescopic rod and a compression spring sleeved on the outside of the telescopic rod; the two ends of the compression spring are respectively supported and abutted against the movable plate 24 and the fixed plate 25, so that when the telescopic rod contracts along its own axial direction, the compression spring can further contract to store elastic potential energy. When the extrusion member 1 moves away from the movable plate 24 to return to its original position, the compression spring can release the elastic potential energy accordingly, so that the telescopic member 26 can be restored in time.

[0058] The specific arrangement of the telescopic member 26 has the beneficial effects of being simple in structure and being able to sensitively achieve telescopic movement along with the displacement of the extrusion member 1 .

[0059] In one possible implementation manner, the external auxiliary positioning member cutting device further includes a machine platform 4 ; the extrusion member 1 is transmission-connected to a driving device on the top of the machine platform 4 ; and the pressure-bearing member 2 is fixedly disposed on the machine platform 4 .

[0060] Specific, combined Figure 1To further explain in detail, the driving device can be specifically but not limited to being set as a stepper motor and being connected to the extrusion member 1 through a screw-nut transmission mechanism. In this way, by accurately controlling the positive and negative step angles output by the stepper motor, the function of driving the extrusion member 1 to move back and forth toward or away from the pressure-bearing member 2 can be achieved.

[0061] In one embodiment, the machine 4 includes an upper frame 41 and a download platform 42; the extrusion member 1 is connected to the top drive in the upper frame 41; the pressure-bearing member 2 is fixedly arranged on the bearing surface of the download platform 42; wherein, an indication display area is provided in the upper frame 41, and a start-stop control switch can also be provided on the bearing surface of the download platform 42.

[0062] Specific, combined Figure 1 To further explain in detail, the machine 4 is specifically configured to include an upper frame 41 and a download platform 42, and the extrusion member 1 is connected to the top drive in the upper frame 41; the pressure member 2 is fixedly arranged on the bearing surface of the download platform 42, so that the extrusion member 1 and the pressure member 2 can be arranged correspondingly in the vertical direction; and an indication display area is provided in the upper frame 41, and the indication display area can be specifically configured as an indicator light or a display screen to intuitively display the working status of the extrusion member 1 to the outside world; the bearing surface of the download platform 42 can also be provided with a start-stop control switch for terminating the operation even under unexpected abnormal working conditions.

[0063] In one embodiment, the machine 4 further includes a waste collection basket 43 disposed inside the unloading platform 42; the waste collection basket 43 is disposed directly below the pressure-bearing member 2 and is used to receive and collect the auxiliary positioning members that fall off during external cutting.

[0064] Specific, combined Figure 3 To further explain in detail, there is a waste collection basket 43 inside the lower platform 42 of the machine 4, and the waste collection basket 43 is arranged directly below the pressure-bearing part 2, so that after the cutting head 23 in the pressure-bearing part 2 cuts the external auxiliary positioning part of the workpiece 3, the waste of the external auxiliary positioning part can fall into the waste collection basket 43 for collection, so as to avoid scattering and facilitate recycling.

[0065] In one possible implementation manner, a plurality of cutting through holes 22 are arranged at intervals on the outer periphery of the accommodating portion 21 ; and the cutting blades 23 are arranged in one-to-one correspondence with the cutting through holes 22 .

[0066] Specific, combined Figure 3 To further explain in detail, at this time, six external auxiliary positioning members are specifically set for the workpiece 3, and six cutting through holes 22 and cutting heads 23 are respectively set one by one. In this way, in one extrusion displacement of the extrusion member 1, efficient and rapid cutting of the six external auxiliary positioning members can be achieved simultaneously.

[0067] In one possible implementation manner, the receiving portion 21 is a receiving groove recessed in the pressure-bearing member 2 , and the receiving groove is consistent with the workpiece in shape and size; an avoidance conduction structure is correspondingly provided between the receiving portion 21 and the cutting through hole 22 .

[0068] Specific, combined Figure 2 To further explain in detail, the accommodating portion 21 is specifically configured as a accommodating groove recessed in the pressure-bearing member 2, and the accommodating groove is consistent with the shape and size of the workpiece, so that it is convenient to stably install the workpiece 3; and an avoidance conductive structure is correspondingly arranged between the accommodating portion 21 and the cutting through hole 22, and the conductive structure can avoid the connecting arm of the external auxiliary positioning member to prevent the extrusion member 1 from directly contacting and extruding it.

[0069] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.
