DETAILED DESCRIPTION

[0039] The utility model will be described in further detail below in combination with the drawings and examples.

[0040] As Figures 1 to 8 shown, the illuminating device for the laser cutting machine disclosed by the embodiment comprises a workbench 1 and a laser cutting head 2 arranged above the workbench 1, and supports 3 are arranged on both sides of the workbench 1, and a multi-axis motion platform 4 for driving the laser cutting head 2 to move is arranged between the top portions of the two supports 3. The side wall of the support 3 facing the workbench 1 is penetrated by a mounting groove 5, and the side wall of the mounting groove 5 is provided with an illuminator 6, and the illuminator 6 comprises a housing 7, a mounting cavity 8 opened on the side of the housing 7 facing the workbench 1, a lamp panel 9 fixed in the mounting cavity 8, a plurality of lamp beads 10 distributed on the side of the lamp panel 9 facing the workbench 1, and a light-transmitting plate 11 for closing the mounting cavity 8. Among them, the light-transmitting plate 11 is made of transparent acrylic plate, which is pasted on the mounting cavity 8 by glue. The lamp beads 10 on the lamp panel 9 are collectively coupled with a control board (not shown), and the control board is connected to the mains through a power line and a power plug (not shown) to drive the lamp beads 10 to operate, thereby realizing illumination, which belongs to the common knowledge in the field and will not be described here.

[0041] In order to realize protection and dust prevention of the illuminator 6 in the idle state, the outer side of the housing 7 is pivoted to the side wall of the mounting groove 5 through a hinge 33 so that the illuminator 6 can rotate in the horizontal direction. In the embodiment, the illuminator 6 has two states:

[0042] The first state is that the illuminator 6 is rotated to the position where the lamp beads 10 on the lamp panel 9 face the workbench 1, so as to illuminate the workbench 1 transversely.

[0043] The second state is that the illuminator 6 is rotated to the position where the light-transmitting plate 11 covers the side wall of the mounting groove 5, so as to complete the storage and protection of the illuminator 6.

[0044] In order to improve the stability of the illuminator 6 in the first state and the second state, the side wall of the mounting groove 5 is further provided with a first locking mechanism for maintaining the illuminator 6 in the first state and a second locking mechanism for maintaining the illuminator 6 in the second state.

[0045] In order to realize the function of the first locking mechanism, the first locking mechanism comprises a locking rod 12 vertically fixed to the side wall of the mounting groove 5 and located on the side of the housing 7 away from the light-transmitting plate 11, a locking piece 13 arranged on the side of the housing 7 away from the light-transmitting plate 11, a locking groove 14 opened on the side of the locking piece 13 away from the housing 7 for clamping the locking rod 12, a first locking hole 15 penetrating the rod body of the locking rod 12, and a second locking hole 16 penetrating the locking piece 13 and communicating with the locking groove 14. In the embodiment, when the illuminator 6 is in the first state, the locking rod 12 is clamped in the locking groove 14 so that the first locking hole 15 is opposite to the second locking hole 16, and a positioning pin 17 is jointly inserted into the first locking hole 15 and the second locking hole 16 to prevent the locking piece 13 from being separated from the locking rod 12. The upper end of the positioning pin 17 is provided with an anti-disengagement piece 34, so as to avoid the positioning pin 17 from being separated from the first locking hole 15 and the second locking hole 16, and further improve the stability of the first locking mechanism.

[0046] In order to realize the function of the second locking mechanism, the second locking mechanism comprises a receiving box 18 fixed to the side wall of the mounting groove 5 and located on the side of the illuminator 6 close to the workbench 1. When the illuminator 6 is in the second state, the illuminator 6 can be flipped into the inner cavity 19 of the receiving box 18, the receiving box 18 is provided with an opening 20 for the illuminator 6 to enter the inner cavity 19, and the upper and lower inner side walls of the receiving box 18 are in interference fit with the upper and lower outer side walls of the illuminator 6, so as to realize the positioning of the illuminator 6 by the friction force generated by extrusion. When the illuminator 6 is in the second state, a space 21 is maintained between the inner side wall of the receiving box 18 away from the illuminator 6 and the end of the illuminator 6, so as to facilitate the operator to open the illuminator 6.

[0047] In order to realize the cleaning function of the light-transmitting plate 11, a sliding seat 22 is arranged in the receiving box 18 close to the bottom of the inner cavity 19, the sliding seat 22 is horizontally long strip-shaped, and its length is equal to or slightly smaller than the horizontal width of the inner cavity 19 of the receiving box 18. The side of the sliding seat 22 close to the illuminator 6 is provided with a wiping piece 23 for contacting the light-transmitting plate 11, the wiping piece 23 is preferably brush hair distributed on the side of the sliding seat 22, and the outer side of the receiving box 18 is provided with a driving mechanism 24 for driving the sliding seat 22 to perform longitudinal reciprocating linear motion in response to external triggering. In the embodiment, when the illuminator 6 is in the second state and the sliding seat 22 performs longitudinal reciprocating linear motion, the wiping piece 23 can slide relative to the light-transmitting plate 11, so as to effectively remove the dust on the surface of the light-transmitting plate 11, thereby achieving the cleaning effect.

[0048] In order to improve the operation efficiency and convenience of the driving mechanism 24, the driving mechanism 24 comprises two driving rods 25 longitudinally sliding through the lower side wall of the storage box 18 and connected to the lower side of the sliding seat 22, and a holding member 26 arranged at the lower end of the driving rod 25. The holding member 26 is in the shape of a horizontal handle, which can effectively improve the holding feeling and make it easier to force.

[0049] In order to realize the storage of the driving mechanism 24, the holding member 26 is provided with a positioning member 27 on each side. The positioning member 27 arranged close to one side of the storage box 18 is provided with a first magnetic member 28, and the lower side of the storage box 18 is provided with a second magnetic member 29 for magnetic attraction of the first magnetic member 28. The first magnetic member 28 and the second magnetic member 29 are preferably permanent magnets, thus having better magnetism and service life.

[0050] In order to improve the stability and smoothness of the longitudinal sliding of the sliding seat 22, two longitudinal guide rods 30 are arranged in the storage box 18, and the sliding seat 22 is provided with a guide hole 31 through which the guide rod 30 slides, so that the sliding seat 22 can slide along the guide rod 30.

[0051] In order to realize the dustproof function when the storage box 18 is exposed, when the illuminator 6 is in the first state, the opening 20 is covered with a dustproof cover 32. Specifically, the upper and lower sides of the opening 20 extend outwardly with positioning strips 35, and the opposite side walls of the two positioning strips 35 are provided with clamping grooves 36 along the length direction of the positioning strips 35 for sliding clamping of the upper and lower edges of the dustproof cover 32, respectively.

[0052] The specific use process is as follows:

[0053] When using the illuminator 6, first insert the hand into the interval 21 between the shell 7 and the inner cavity 19 of the storage box 18, and overcome the friction between the inner side wall of the storage box 18 and the shell 7 to open the illuminator 6 outwardly from the storage box 18. When the illuminator 6 is turned to the position where the lamp beads 10 on the lamp panel 9 face the workbench 1 (i.e. the first state), the locking member 13 on the back of the shell 7 is butted against the locking rod 12 through the locking groove 14, so that the first locking hole 15 on the locking rod 12 can be opposite to the second locking hole 16 on the locking member 13. At this time, the positioning pin 17 is inserted into the second locking hole 16 and the first locking hole 15 in sequence, so that the locking of the locking member 13 and the locking rod 12 can be completed, and the locking of the illuminator 6 in the first state is completed.

[0054] In the first state, the power line (not shown) on the illuminator 6 is connected to the mains through the power plug (not shown) to power on the lamp beads 10 on the lamp panel 9, so as to illuminate the workbench 1 through the light-transmitting plate 11. In order to prevent dust from entering the inner cavity 19 of the storage box 18, the dustproof cover 32 is slidably clamped in the clamping groove 36 of the two positioning strips 35. When the dustproof cover 32 slides to the bottom of the clamping groove 36, it can cover the opening 20 of the inner cavity 19, thereby playing a dustproof role.

[0055] After the illuminator 6 is used, the power plug of the power line is disconnected from the mains to stop the lamp beads 10 from working. Then, the dustproof cover 32 is pulled out of the two positioning strips 35 to expose the opening 20 of the inner cavity 19. At this time, the positioning pin 17 is pulled out of the first locking hole 15 and the second locking hole 16 to release the locking of the locking member 13 and the locking rod 12, so that the operator can push the illuminator 6 into the inner cavity 19 of the storage box 18, and the illuminator 6 is positioned by the interference fit between the side wall of the inner cavity 19 and the outer side of the shell 7.

[0056] When the illuminator 6 is in the closed state, the light-transmitting plate 11 abuts against the wiping member 23 on the sliding seat 22. At this time, the operator drives the gripping member 26 to reciprocate up and down by overcoming the magnetic attraction force between the first magnetic member 28 and the second magnetic member 29, so as to drive the driving rod 25 and the sliding seat 22 to translate up and down, thereby driving the wiping member 23 to wipe off the dust on the surface of the light-transmitting plate 11. After the dust is cleaned, the gripping member 26 is pushed to the uppermost position and positioned by the magnetic attraction force between the first magnetic member 28 and the second magnetic member 29, thereby completing the storage of the driving mechanism 24.
