Description

Auxiliary trimming device for lighting accessories Technical Field

[0001] The present invention relates to the technical field of lighting accessory production, and in particular to an auxiliary trimming device for lighting accessories. Background Art

[0002] Lighting accessories are the components needed for lighting fixtures. Among them, light strips refer to LED lights that are welded to copper wires or strip-shaped flexible circuit boards using a special processing technology, and then connected to a power source to emit light. They are named because they look like a light strip when they emit light.

[0003] During the production of light strips, the light strips need to be trimmed. The existing trimming process is performed manually, where the entire light strip is placed into a cutting device to adjust and align the edges, and then the light strips are trimmed using a cutter.

[0004] Since the existing cutting device is fixed and cannot be adjusted, the cutting device cannot effectively fix the light strip, resulting in most light strips being manually fixed by hand during cutting, making the cutting effect difficult to uniform and prone to safety accidents.

[0005] The present invention aims to design a trimming device capable of instantly limiting the position of a light strip.

[0006] Summary of the Invention

[0007] In order to overcome the shortcomings of existing cutting devices that do not have a mechanism to limit and fix the light strip, resulting in the need for manual pressing and fixing of the cut edges, inconsistent cutting effects and prone to safety accidents, the present invention provides a lighting accessory auxiliary cutting device that can limit the light strip.

[0008] An auxiliary trimming device for lighting accessories includes a base plate, a placement frame and a safety baffle. The placement frame is fixed to the base plate by a bracket, and the safety baffle is fixed to the right side of the placement frame. The device also includes a guide bevel rod, a collection frame, a cutting mechanism and a limiting mechanism. The collection frame is arranged at the right end of the placement frame and is fixed thereto. The collection frame is provided with a pull-out drawer, the guide bevel rod is arranged on the upper part of the collection frame, the cutting mechanism is arranged on the right side of the base plate for trimming the light strip, and the limiting mechanism is arranged on the right side of the placement frame for limiting the light strip.

[0009] Furthermore, the cutting mechanism includes a servo motor, a cutter, a rotating shaft and a transmission assembly. The servo motor is fixed to the right end of the base plate through a bracket. The rotating shaft is symmetrically arranged and limited to rotate on the left and right sides of the placement frame. One of the rotating shafts is connected to the output shaft of the servo motor through a coupling. The cutter key is connected to the rotating shaft, and the left and right rotating shafts are transmitted through the transmission assembly.

[0010] Furthermore, the transmission assembly consists of two pulleys and a transmission belt. The pulleys are key-connected to the rear ends of the rotating shaft, and the transmission belt is wound around the two pulleys.

[0011] Furthermore, the limiting mechanism includes a limiting baffle, a first return spring and an L-shaped push block. The limiting baffle slides in a limited manner at the front end of the placement frame and is connected thereto. The limiting baffle is connected to the placement frame with a first return spring. The L-shaped push block key is connected to the rotating shaft, and the L-shaped push block can push the end of the limiting baffle.

[0012] Furthermore, it also includes a clamping mechanism, which includes a push plate, a clamping block and a protrusion. The push plates are slidably connected to the left and right sides of the placement frame. The clamping blocks are fixed to the opposite sides of the push plates. The protrusion key is connected to the middle part of the rotating shaft, and the protrusion can contact and push the push plate.

[0013] Furthermore, it also includes a pressing plate and a second return spring. The pressing plate is slidably connected to the safety baffle and the second return spring is connected between the two. The L-shaped push block can contact and push the pressing plate.

[0014] Furthermore, it also includes a feeding plate and a guide rod, the guide rod is symmetrically fixed to the left and right sides of the placement frame, and the feeding plate is slidably connected to the guide rod.

[0015] Furthermore, it also includes a blanking plate, which is fixed to the right end of the placement frame. The beneficial effects are:

[0016] 1. The servo motor drives the shaft to rotate, thereby controlling the cutter to trim the light strip. During this period, the L-shaped push block controls the lifting and lowering of the limit baffle, which can block and limit the end of the light strip. Compared with the existing method of manually determining the trimming position, this device can maintain a uniform trimming position, improve the production quality of the light strip, and also reduce the safety hazards caused by manual hand-held positioning.

[0017] 2. A clamping mechanism and a pressing plate are provided. When the cutter is trimming the light strip, the clamping block can clamp and fix the left and right sides of the light strip, and the pressing plate can press and fix the front end of the light strip, which improves the stability of the light strip during trimming and is conducive to improving the trimming quality.

[0018] 3. The light strip is pushed through the feeding plate, which avoids the safety disadvantages of manual pushing and improves the safety of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The technical solution of the present invention will be further described below with reference to the accompanying drawings. Example 1

[0030] An auxiliary trimming device for lighting accessories, as shown in Figures 1 and 2, includes a base plate 1, a placement frame 2 and a safety baffle 3. The placement frame 2 is fixed to the base plate 1 by a bracket, and the safety baffle 3 is fixed to the right side of the placement frame 2. It also includes a guide bevel rod 4, a collection frame 5, a cutting mechanism 6 and a limiting mechanism 7. The collection frame 5 is arranged at the right end of the placement frame 2 and is fixed thereto. The collection frame 5 is provided with a pull-out drawer, and the guide bevel rod 4 is arranged on the upper part of the collection frame 5; a through groove is opened at the relative position of the guide bevel rod 4, and the through groove can guide and collect the edge materials of the light strip. The edge materials of the light strip are introduced into the collection frame 5 by the guide bevel rod 4 for unified collection. The cutting mechanism 6 is arranged on the right side of the base plate 1 for trimming the light strip, and the limiting mechanism 7 is arranged on the right side of the placement frame 2 for limiting the light strip.

[0031] As shown in Figures 1 and 3, the cutting mechanism 6 includes a servo motor 601, a cutter 602, a rotating shaft 603 and a transmission assembly 604. The servo motor 601 is fixed to the right end of the base plate 1 through a bracket. The rotating shaft 603 is symmetrically arranged and limited to rotate on the left and right sides of the placement frame 2. One of the rotating shafts 603 is connected to the output shaft of the servo motor 601 through a coupling. The cutter 602 is keyed to the rotating shaft 603, and the left and right rotating shafts 603 are driven by the transmission assembly 604; the transmission assembly 604 consists of two pulleys and a transmission belt. The pulleys are respectively keyed to the rear end of the rotating shaft 603, and the transmission belt is wound around the two pulleys. Turning on the servo motor 601 can drive the rotating shaft 603 to rotate, and the left and right rotating shafts 603 rotate synchronously through the transmission assembly 604. The cutter 602 is driven by the rotating shaft 603 to rotate. The cutter 602 is tangent to the front boundary of the placement frame 2. Therefore, the light strip can be pushed to the front side of the placement frame 2 and the cutter 602 can perform edge trimming.

[0032] As shown in Figures 1, 4 and 5, the limiting mechanism 7 includes a limiting baffle 701, a first return spring 702 and an L-shaped push block 703. The limiting baffle 701 is limited and slides at the front end of the placement frame 2 and is connected thereto. The first return spring 702 is connected between the limiting baffle 701 and the placement frame 2. The L-shaped push block 703 is key-connected to the rotating shaft 603. The L-shaped push block 703 can push the end of the limiting baffle 701; the limiting baffle 701 can slide up and down under the action of the first return spring 702, and the limiting baffle 701 can The light strip is blocked and limited in the horizontal direction, so in the initial state, the light strip is pushed to the end of the placement frame 2 and close to the limit baffle 701, and then the servo motor 601 is turned on to drive the cutter 602 to rotate through the rotating shaft 603. When the cutter 602 rotates to perform edge trimming, the L-shaped push block 703 can contact and push the end of the limit baffle 701 to slide downward. At this time, the limit baffle 701 no longer blocks and limits the light strip, so after the edge trimming is completed, the light strip can be pushed to the right for unloading, and the edge material of the light strip will slide into the collection frame 5. Example 2

[0033] On the basis of Example 1, as shown in Figures 1 and 6, a clamping mechanism 8 is also included, which includes a push plate 801, a clamping block 802 and a protrusion 803. The push plate 801 is slidably connected to the left and right sides of the placement frame 2. The clamping block 802 is fixed to the opposite side of the push plate 801, and the protrusion 803 is keyed to the middle part of the rotating shaft 603. The protrusion 803 can contact and push the push plate 801; a torsion spring is connected between the protrusion 803 and the rotating shaft 603. When the light strip is placed in the placement frame 2, the light strip will be located between the clamping blocks 802. When the rotating shaft 603 drives the cutter 602 to cut the light strip, the protrusion 803 can push the push plate 801, and then the clamping block 802 can clamp the light strip. The effect of this mechanism is that when the cutter 602 cuts the light strip, the clamping block 802 can clamp and fix the light strip on the left and right sides, thereby ensuring the stability of the light strip during cutting.

[0034] As shown in Figures 1, 7 and 8, it also includes a pressing plate 9 and a second return spring 901. The pressing plate 9 is slidably connected to the safety baffle 3 and a second return spring 901 is connected between the two. The L-shaped push block 703 can contact and push the pressing plate 9; when the cutter 602 is in the initial position, the L-shaped push block 703 can push the pressing plate 9 to slide upward. At this time, the second return spring 901 is in an extended state, and the pressing plate 9 can press and fix the light strip. It can be seen from the figure that when the cutter 602 rotates to the trimming angle, the L-shaped push block 703 will rotate at the same time and no longer push the pressing plate 9. The pressing plate 9 will slide downward under the action of the second return spring 901, so that the light strip can be pressed and fixed, which plays a stabilizing role for the light strip during the trimming process.

[0035] As shown in Figure 9, it also includes a feeding plate 10 and a guide rod 1001. The guide rod 1001 is symmetrically fixed to the left and right sides of the placement frame 2, and the feeding plate 10 is slidably connected to the guide rod 1001; the feeding plate 10 is located in the placement frame 2, and the feeding plate 10 can push the light strip without manual pushing through handheld placement, thereby improving the safety index.

[0036] As shown in FIG1 , a blanking plate 11 is also included, which is fixed to the right end of the placement frame 2 ; the blanking plate 11 is provided with an inclined surface, and the trimmed light strip will slide down through the blanking plate 11 for easy unified collection.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
