Description

Technical Field

[0001] This application relates to the field of lighting processing technology, and in particular to a cutting system for cutting and peeling off the coating at the end of a lamp tube. Background Technology

[0002] Tubular lighting fixtures generally consist of a lamp tube, a diffuser film covering the outer circumference of the lamp tube, and end caps at both ends of the lamp tube. The lamp tube is usually made of a transparent material such as glass, and the end caps are fixed to both ends of the lamp tube by adhesive bonding.

[0003] When bonding and fixing the ends to the lamp tube, the diffuser film at both ends of the lamp tube is relatively smooth and difficult to bond and fix. Therefore, it is necessary to cut and peel off the diffuser film at both ends of the lamp tube. Since the diffuser film is a film layer structure covering the outer circumference of the lamp tube, this film layer structure is tightly attached to the outer circumference of the lamp tube, and manually cutting and peeling off the film at the end of the lamp tube is inefficient. Utility Model Content

[0004] Therefore, it is necessary to provide a cutting system for cutting and peeling the coating off the end of a lamp tube to address the aforementioned technical problems.

[0006] The track for conveying the lamp tube includes a feeding area, a working area and a discharging area arranged in sequence. The working area has a plurality of positioning slots arranged along the lamp tube conveying direction for temporarily holding the lamp tube.

[0007] A feeding assembly is used to transfer the lamp tube from one positioning slot to the next positioning slot in a progressive manner.

[0008] A first cutting device is used to circumferentially cut the end of the diffusion film, including a drive assembly for driving the lamp tube to rotate and a first blade for cutting the diffusion film when the lamp tube rotates.

[0009] The second cutting device is used to side-cut the end of the diffusion film, and includes a second blade that can move along the axial direction of the lamp tube and enter and exit the working area.

[0010] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0011] Optionally, the feeding assembly includes a transfer frame, a translation cylinder for driving the transfer frame to move horizontally along the conveying direction, and a lifting cylinder for driving the transfer frame to move vertically. The transfer frame is provided with a plurality of support grooves arranged along the conveying direction.

[0012] Optionally, the drive assembly includes a drive roller that drives the lamp tube to rotate using surface friction.

[0013] Optionally, the first blade rotates coaxially with the drive roller.

[0014] Optionally, the drive rollers are arranged in pairs, and the lamp tube is located between the two drive rollers during operation.

[0015] Optionally, the cutting system includes a lifting assembly that drives the first cutting device to move up and down. Before the lamp tube is in place, the lifting assembly moves the first cutting device away from the working position. After the lamp tube is in place, the lifting assembly moves the first cutting device to the working position.

[0016] Optionally, the cutting system includes a centering device located upstream of the working area to center the lamp tube, the centering device including two push rods on opposite sides with a fixed horizontal travel.

[0017] Optionally, the outer side of the working area is provided with two side baffles that restrict the axial position of the lamp tube.

[0018] Optionally, the top of the side baffle is inclined.

[0019] Optionally, the working area is horizontally arranged, and the feeding area and the discharging area are arranged at an angle relative to the working area.

[0020] The cutting system used in this application for cutting and peeling off the coating at the end of a lamp tube has at least the following technical advantages:

[0021] This application describes a track for transporting the lamp tubes and a feeding assembly, which work together to achieve automatic loading and unloading of the lamp tubes. A first cutting device drives the lamp tube to rotate via a drive assembly, and automatically performs a circumferential cut on the end of the diffusion film using a first blade. A second cutting device automatically performs a side cut on the end of the diffusion film using a second blade that moves in and out of the working blade. The entire system achieves fully automatic cutting of the diffusion film at the end of the lamp tube, improving the efficiency of cutting and peeling off the coating at the end of the lamp tube.

[0041] One embodiment of this application provides a cutting system for cutting and peeling the coating off the end of a lamp tube, hereinafter referred to as the cutting system.

[0042] See Figure 1The tubular luminaire includes a lamp tube 010 and a diffusion film 011 covering the outer circumference of the lamp tube 010. A cutting system is used to cut and peel off the diffusion film 011 at both ends of the lamp tube 010. The cutting system includes a track 100 for conveying the lamp tube 010, a feeding assembly 300, a first cutting device 500, and a second cutting device 700. The track 100, the feeding assembly 300, the first cutting device 500, and the second cutting device 700 are all arranged in pairs opposite the axial ends of the lamp tube 010.

[0043] The feeding assembly 300 is used to transport the lamp tube 010 on the track 100. The first cutting device 500 is used to cut the diffusion film 011 at the end of the lamp tube 010 circumferentially, referred to as circumferential cutting. The second cutting device 700 is used to cut the diffusion film 011 at the end of the lamp tube 010 axially, referred to as lateral cutting. After the circumferential cutting and lateral cutting are completed, the diffusion film 011 at the end of the coated lamp tube 010 is peeled off. As a production and processing machinery, the cutting system is placed horizontally during use. The system as a whole and each sub-component have a vertical direction along the direction of gravity to distinguish the top and bottom, as well as a horizontal direction perpendicular to the direction of gravity.

[0044] See Figure 2 The track 100 for conveying the lamp tube 010 includes a feeding area 110, a working area 120, and a discharging area 130 arranged sequentially. The lamp tube 010 enters the working area 120 from the feeding area 110. After the diffusion film 011 at the end of the lamp tube 010 is cut and peeled off in the working area 120, it leaves the working area 120 and proceeds to the discharging area 130. The entire conveying process forms a relative upstream direction 101 and a relative downstream direction 102 according to the change in the conveying position.

[0045] The working area 120 is horizontally positioned, while the feeding area 110 and the discharging area 130 are arranged at an angle relative to the working area 120. The upstream direction 101 of the feeding area 110 is higher than the working area 120, and the downstream direction 102 of the discharging area 130 is lower than the working area 120. The working area 120 has several positioning slots 122 arranged along the conveying direction of the lamp tubes 010 for temporarily holding the lamp tubes 010. The working area 120, feeding area 110, and discharging area 130 are not strictly divided according to physical components, but rather according to their functions. The feeding area 110 refers to the area where the lamp tubes 010 can automatically move forward along the conveying direction under gravity and enter the working area 120. The discharging area 130 refers to the area where the lamp tubes 010 can automatically move forward along the conveying direction under gravity and leave the working area 120. Specifically, the feeding area 110 may be equipped with a feeding track 111, and the discharging area 130 may be equipped with a discharging track 131. The working area 120 may be equipped with a horizontal track 121 with positioning slots 122. The three components are not strictly required to be connected; for example, they can be axially offset at area switching points. Axial offset connection refers to adjacent areas having overlapping regions in the conveying direction, with the overlapping regions axially offset. The angle of the overlapping regions can be adaptively adjusted. For example, when the horizontal track 121 connects with the discharge track 131, the connection point 123 is adaptively tilted. This tilted area allows the lamp tube 010 to move along the conveying direction under gravity and is functionally part of the discharge track 131.

[0046] See Figure 2 and Figure 3 The cutting system includes a centering device 200 located upstream of the working area 120 to center the lamp tube 010. Centering the lamp tube 010 means ensuring that the axial position of the lamp tube 010, temporarily held in the positioning groove 122 before the diffusion film 011 is cut, meets the expected requirements. The centering device 200 includes two oppositely arranged push rods 210 with a fixed horizontal travel stroke. Further, two side baffles 220 are provided on the outer side of the working area 120 (along the axial direction of the lamp tube 010) to restrict the axial position of the lamp tube 010. The tops of the side baffles 220 are inclined, expanding outwards from bottom to top along the direction of gravity. The height of the side baffles 220 is higher than the plane of the working area 120, so that the lamp tube 010 remains between the two side baffles 220 during movement in different positioning grooves 122, preventing axial misalignment of the lamp tube 010. The centering device 200 is located upstream of the side baffle 220. After the lamp tube 010 is centered, it enters the working area 120 and is restricted by the side baffle 220 until the circumferential cutting and side cutting are completed.

[0047] See Figure 4The feeding assembly 300 is used to transfer the lamp tube 010 from one positioning slot 122 to the next positioning slot 122 in a progressive manner. The feeding assembly 300 includes a transfer frame 310, a translation cylinder 320 for driving the transfer frame 310 to move horizontally along the conveying direction, and a lifting cylinder 330 for driving the transfer frame 310 to move vertically. The transfer frame 310 is provided with a plurality of support slots 311 arranged along the conveying direction, which are used to support the lamp tube 010. The support slots 311 and the positioning slots 122 are spaced equidistantly along the conveying direction. Specifically, adjacent positioning slots 122 are respectively the upstream positioning slot 125 and the downstream positioning slot 126. The rotation process includes: (1) the transfer frame 310 lifts the lamp tube 010 through the support groove 311, causing the lamp tube 010 to leave the upstream positioning groove 125; (2) the transfer frame 310 enters the upper part of the downstream positioning groove 126 along the conveying direction; (3) the transfer frame 310 moves vertically downward, causing the lamp tube 010 to enter the downstream positioning groove 126, and continues to move downward to cause the lamp tube 010 to leave the support groove 311; (4) the transfer frame 310 returns to the lower part of the upstream positioning groove 125 in the opposite direction of the conveying direction. Specifically, the cutting system includes a frame 400, which is connected and fixed to a first support frame 410 by a vertically moving lifting cylinder 330, and the first support frame 410 is connected and fixed to the transfer frame 310 by a translation cylinder 320 that moves horizontally along the conveying direction.

[0048] See Figure 5 The first cutting device 500 is used to perform circumferential cutting on the end of the diffusion film 011. The first cutting device 500 includes a drive assembly for driving the lamp tube 010 to rotate and a first blade for cutting the diffusion film 011 when the lamp tube 010 rotates. The drive assembly includes a drive roller 510, the surface of which contacts the outer peripheral surface of the lamp tube 010. When the drive roller 510 rotates, it drives the lamp tube 010 to rotate by friction. Further, the first blade rotates coaxially with the drive roller 510. The first blade may be, for example, a blade provided on a rotating cutter head that rotates coaxially with the drive roller 510. The drive rollers 510 are arranged in pairs, and the lamp tube 010 is located between the two drive rollers 510 during operation. The first cutting device 500 is disposed above the working area 120, and the cutting system includes a lifting assembly for driving the first cutting device 500 to move. Before the lamp tube 010 is in place, the lifting assembly moves the first cutting device 500 away from the working area. After the lamp tube 010 is in place, the lifting assembly moves the first cutting device 500 to the working position, which is the working position of the first cutting device 500 when performing the cutting action. The cutting system includes a frame 400, and the lifting assembly includes a second support frame on which the first cutting device 500 is fixed. The second support frame is connected and fixed to the frame by a vertically running lifting cylinder.

[0049] See Figure 6The second cutting device 700 is used to side-cut the end of the diffusion film 011, and includes a second blade 730 that can move along the axial direction of the lamp tube 010. The cutting system includes a frame 400, and the second blade 730 is disposed on a third support frame 710. The third support frame 710 is connected and fixed to the frame 400 by a transfer cylinder 720 that runs along the axial direction of the lamp tube 010, so as to facilitate the side-cutting of the lamp tube 010 temporarily placed in the positioning groove 122 during the process of the second blade 730 entering and leaving the working area 120.

[0050] The cutting system provided in the various embodiments of this application includes a track 100 and a feeding assembly 300 that work together to automatically load and unload the lamp tube 010. A first cutting device 500 drives the lamp tube 010 to rotate, causing a first blade to automatically circumferentially cut the end of the diffusion film 011. A second cutting device 700 uses a second blade 730 to axially move in and out of the working area 120 to automatically side-cut the end of the diffusion film 011. After the lamp tube 010 has undergone circumferential and side-cutting, the diffusion film 011 is automatically peeled off, improving the efficiency of peeling the film off the end of the lamp tube 010.

[0051] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0052] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
