[0032] Refer to Figure 1 , Figure 1A schematic diagram of a bidirectional cutting mechanism 1 for a lamp silicone strip provided in an embodiment of the present invention shows a method of cutting the lamp silicone strip 13 horizontally and vertically so that the lamp silicone strip 13 meets the shape and size feature requirements during installation. In a non-limiting embodiment, the bidirectional cutting mechanism 1 includes:

[0033] A base 11 having a tool mounting groove 111 formed thereon;

[0034] A tool 112 installed in the tool installation slot 111;

[0035] A transverse cutting positioning groove 114, which is disposed beside the tool installation groove 111 and communicates with the tool installation groove 111;

[0036] A longitudinal cutting positioning groove 113, which is disposed beside the tool installation groove 111 and communicates with the tool installation groove 111;

[0037] The tool 112 is extendedly arranged in the tool installation groove 111 so that the tool 112 is respectively connected to the transverse cutting positioning groove 114 and the longitudinal cutting positioning groove 113; the blade of the tool 112 is arranged upward. Figure 1 and Figure 2 In the non-limiting embodiment shown, the extension direction of the tool mounting groove 111 is a straight line, and accordingly, the tool 112 is also arranged in a straight line. Those skilled in the art should understand that the tool mounting groove 111 can be arranged into other structures besides a straight line according to the requirements of the cutting process, and the tool 112 can be adaptively adjusted according to the shape structure of the tool mounting groove 111.

[0038] When cutting, you can refer to the following cutting methods: Figure 1 As shown, when the lamp rubber strip 13 is cut transversely, the lamp rubber strip 13 can be positioned transversely in the transverse cutting positioning groove 114, and the lamp rubber strip 13 can be inserted into the tool installation groove 111, and the tool 112 and the ruler can be used to calibrate the axial length of the section to be cut transversely on the lamp rubber strip 13, and then a downward cutting force is applied to the lamp rubber strip 13 in the transverse direction, and finally a preset cutting length is cut transversely; when the lamp rubber strip 13 is cut longitudinally, the lamp rubber strip 13 can be positioned longitudinally at the junction of the longitudinal cutting positioning groove 113 and the tool installation groove 111, and the tool 112 and the ruler can be used to calibrate the transverse thickness of the section to be cut longitudinally on the lamp rubber strip 13, and then a downward cutting force is applied to the lamp rubber strip 13 in the longitudinal direction, and finally a preset cutting length is cut longitudinally.

[0039] In the following text and throughout the specification, the term "lateral" or "laterally" refers to the direction perpendicular to the axis of the lamp strip 13; the term "longitudinal" or "longitudinally" refers to the direction parallel to the axis of the lamp strip 13.

[0040] In order to enable the cut waste or the remaining material to be discharged smoothly, in Figure 2 the illustrated non-limiting embodiment, a longitudinal discharge through hole 1131 is provided in the longitudinal cutting positioning groove 113, which penetrates the base 11 in the vertical direction.

[0041] In order to enable the cut waste or the remaining material to be discharged in a timely manner, in Figure 2 and Figure 3 the illustrated non-limiting embodiment, the longitudinal discharge through hole 1131 is communicated with the tool mounting groove 111, wherein the tool 112 is arranged at the interface between the longitudinal discharge through hole 1131 and the tool mounting groove 111, so that the lamp strip 13 separated by longitudinal cutting can be discharged through the longitudinal discharge through hole 1131 in a timely manner.

[0042] Since the lamp strip 13 has a certain flexibility and elasticity, it is prone to deformation during the cutting process. In order to stably position the lamp strip 13 during longitudinal cutting and prevent problems such as tilting, side bending, and curling, a cutting positioning block 12 is installed in the longitudinal cutting positioning groove 113. A cutting positioning through hole 121 is provided in the cutting positioning block 12, which penetrates the cutting positioning block 12 in the vertical direction. Among them, the cutting positioning through hole 121 is divided into a first positioning through hole 1211 and a second positioning through hole 1212 with the tool 112 as the boundary in the vertical direction; the first positioning through hole 1211 and the longitudinal discharge through hole 1131 at least partially overlap in the vertical direction; the second positioning through hole 1212 and the tool mounting groove 111 at least partially overlap in the vertical direction. Finally, the longitudinally cut part falls into the longitudinal discharge through hole 1131 along the first positioning through hole 1211, while the part to be retained falls into the tool mounting groove 111. Those skilled in the art should understand that the cutting positioning block 12 is arranged to be able to adjust its relative position with respect to the tool mounting groove 111, so as to adjust the ratio of the first positioning through hole 1211 and the second positioning through hole 1212 in the lateral direction according to the cutting process requirements, and further adjust the lateral thickness of the section to be longitudinally cut off according to the cutting process requirements.

[0043] As a further improvement, a longitudinal receiving hole (not shown in the figure) is provided on the bottom wall of the tool mounting groove 111 directly below the second positioning through hole 1212, so that the part to be retained after longitudinal cutting is received in the longitudinal receiving hole.

[0044] InFigure 3 In the illustrated non-limiting embodiment, the cross-sectional shape of the silicone strip of the lamp to be cut is adapted to the cross-sectional shape of the cutting positioning through hole 121. Thus, further, when the silicone strip 13 of the lamp to be cut passes through the cutting positioning through hole 121, it can be fitted to the side wall of the cutting positioning through hole 121, and further, it can keep advancing in the vertical direction (the direction indicated by arrow A) during the longitudinal cutting process, thereby ensuring the cutting angle and accuracy, and at the same time, it can also prevent the silicone strip 13 of the lamp from bending, thereby improving the smoothness when the silicone strip 13 of the lamp passes through the cutting positioning through hole 121.

[0045] In Figures 2 to 4 In the illustrated non-limiting embodiment, the tool mounting groove 111 has:

[0046] A first side wall 1111, which is adjacent to the transverse cutting positioning groove 114; and

[0047] A second side wall 1112, which is adjacent to the longitudinal cutting positioning groove 113;

[0048] Wherein, the tool 112 is arranged to be fitted to the second side wall 1112. As a further improvement, one or more tool mounting blocks 1113 are installed in the tool mounting groove 111, and the tool 112 can be stably clamped and installed between the second side wall 1112 and the tool mounting block 1113. Those skilled in the art should understand that in other embodiments, other mounting structures / methods can also be used to mount the tool 112, as long as the tool 112 can finally be stably fitted to the second side wall 1112.

[0049] In order to accommodate the waste materials cut transversely, in Figure 3 and Figure 4 In the illustrated non-limiting embodiment, a transverse cutting relief groove 1141 is formed in the second side wall 1112 and is aligned with the transverse cutting positioning groove 114 in the transverse direction. In this way, the waste materials cut transversely can fall into the transverse cutting relief groove 1141 along the trend.

[0050] As a further improvement, in order to enable the waste materials cut transversely to be discharged in time, a transverse discharge through hole is formed in the bottom wall of the tool mounting groove 111 and is aligned with the transverse cutting relief groove 1141 in the vertical direction. In this way, the waste materials cut transversely are discharged through the transverse discharge through hole under the action of pressure and its own gravity.

[0051] As a further improvement, in order to enable the waste materials cut longitudinally to pass through the longitudinal discharge through hole 1131 unobstructed, a support assembly is arranged in a supporting manner below the base 11 to at least vacate the space directly below the longitudinal discharge through hole 1131 (Figure 5 in the direction indicated by arrow B). This enables the longitudinally cut part to be smoothly discharged downward through the longitudinal blanking through-hole 1131. Those skilled in the art should understand that in other embodiments, other structures / methods can also be used to arrange the support components, as long as the support components can finally vacate at least the space directly below the longitudinal blanking through-hole 1131.

[0052] Those skilled in the art should also understand that in order to collect the cut waste, corresponding waste collection devices can be arranged directly below the longitudinal blanking through-hole 1131 and directly below the transverse blanking through-hole.
