[0021] Unless otherwise defined, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0022] Reference to "embodiments" in the present invention means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive, independent, or alternative to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments.

[0023] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0024] like Figure 1-4 As shown, a novel edge sealing head structure of the present invention comprises a laser head connecting component 1, a pendulum component, a galvanometer module component and a focusing protection component which are sequentially arranged from top to bottom. The pendulum component comprises a pendulum shell 41, a pendulum stator lens barrel 42 and a pendulum mover lens barrel 43 are arranged in the pendulum shell 41, the pendulum mover lens barrel 43 is sleeved on the pendulum stator lens barrel 42, a first lens mounting position is arranged in the pendulum mover lens barrel 43, a first wedge-shaped mirror 44 is arranged on the first lens mounting position, and an angle exists between the upper and lower surfaces of the first wedge-shaped mirror 44.

[0025] By setting the first wedge-shaped mirror 44, the laser can be refracted when passing through. With the cooperation of the oscillating stator lens barrel 42 and the oscillating mover lens barrel 43, the emitted light spot is annular. Combined with the adjustment of the galvanometer module assembly, the area of ​​the single output light spot can be effectively increased. While melting the glue layer, it will also irradiate the plate, increasing the heating area, making the glue layer melt more evenly, which can meet the use needs of processing personnel and effectively improve the competitiveness of the enterprise.

[0026] Since there is an angle between the upper and lower surfaces of the first wedge-shaped mirror 44, the upper surface is a plane and the lower surface is a surface with an inclined angle, wedge-shaped mirrors with different angles can be selected according to customer needs for flexible adaptation.

[0027] The optimal angle between the upper and lower surfaces of the first wedge-shaped mirror 44 is between 0.01 and 1 degrees. In this embodiment, the angle between the upper and lower surfaces of the first wedge-shaped mirror 44 is 0.5 degrees, so that the circular ring of the emitted light spot infinitely approaches a solid circle, making the glue layer melt more evenly.

[0028] The cycloid assembly further includes a collimating lens 45 and a collimating fixture 46. A collimating installation position is provided on the cycloid housing 41, and the collimating lens 45 is provided in the collimating installation position. The collimating fixture 46 can fix the collimating lens 45 in the collimating installation position.

[0029] The novel edge sealing head structure also includes a position fixing part. A second wedge mirror assembly is also arranged in the pendulum shell 41. The second wedge mirror assembly includes a wedge mirror mounting tube 47 and a second wedge mirror 48 fixedly arranged in the wedge mirror mounting tube 47. The second wedge mirror 48 has the same shape as the first wedge mirror 44. The upper end of the pendulum mover barrel 43 is sleeved on the wedge mirror mounting tube 47. An upper angle adjustment rotating part is fixedly arranged on the wedge mirror mounting tube 47. The position fixing part can prevent the wedge mirror mounting tube 47 from relative sliding during the rotation of the pendulum mover barrel 43. An adjustment window 410 cooperating with the upper angle adjustment rotating part is arranged on the pendulum shell 41. The adjustment window 410 can facilitate personnel to rotate and adjust the upper angle adjustment rotating part. The second wedge mirror 48 can change the spot size by rotating relative to the first wedge mirror 44.

[0030] By setting the second wedge mirror assembly, the size of the circular ring emitted by the light spot can be effectively controlled, and the usage requirements of different users can be flexibly adapted. The second wedge mirror 48 is driven to rotate relative to the first wedge mirror 44 by the upper angle adjustment rotating member, thereby changing the light output angle and realizing the control of the circular ring size. In addition, by setting the position fixing member, an external force fixed on the swinging rotor barrel 43 can be added to the second wedge mirror assembly, so that the swinging rotor barrel 43 drives the second wedge mirror assembly to rotate, and prevents the second wedge mirror assembly and the first wedge mirror 44 from rotating relative to each other. In addition, the external force can ensure that the second wedge mirror assembly can be rotated and adjusted relative to the swinging rotor barrel 43, rather than being locked. The processing personnel can rotate the upper angle adjustment rotating member through the adjustment window 410 to rotate the second wedge mirror 48 relative to the first wedge mirror 44.

[0031] The novel edge banding head structure also includes a cycloid size adjustment member 6, which is fixedly arranged on the outside of the adjustment window 410. The cycloid size adjustment member 6 includes an adjustment mounting seat 61, an adjustment reset spring (not shown in the figure) and a push-rotate adjustment member. The adjustment mounting seat 61 is fixedly arranged on the outer surface of the cycloid shell 41. The push-rotate adjustment member includes a pressing end 62 and a rotation adjustment end 63. The adjustment mounting seat 61 is provided with a mounting hole 611 that matches the push-rotate adjustment member. The rotation adjustment end 63 passes through the mounting hole 611 and is arranged in the adjustment window 410. The adjustment reset spring sleeve is provided. At the rotation adjustment end 63, a limiting boss 632 is provided on the rotation adjustment end 63, and the area of ​​the limiting boss 632 is larger than the mounting hole 611. The two ends of the adjustment reset spring are limited by the outer surface of the pendulum shell 41 and the limiting boss 632 respectively. Pressing the rotation adjustment member can rotate and move linearly relative to the adjustment mounting seat 61. The upper angle adjustment rotating member is the upper adjustment rotating gear 49 (the gear teeth are not drawn in the figure). The end of the rotation adjustment end 63 is provided with teeth 631 with the upper adjustment rotating gear 49. Pressing the rotation adjustment member can drive the upper adjustment rotating gear 49 to rotate.

[0032] By setting the pendulum circle size adjustment piece 6, the adjustment tool can be effectively integrated into the new edge sealing head structure. When in use, it is only necessary to press the pressing end 62 to make the teeth 631 of the rotating adjustment end 63 close to the upper adjusting rotating gear 49 until the teeth 631 are engaged with the upper adjusting rotating gear 49. The processing personnel then rotates the pressing and rotating adjustment piece to control the rotation of the wedge mirror mounting tube 47. After the adjustment is completed, release your hand, and under the action of the adjustment reset spring, press the rotating adjustment piece to reset it, and the rotating adjustment end 63 is released from the upper adjusting rotating gear 49.

[0033] A protective shell 64 is provided on the outer periphery of the cycloid size adjusting member 6 . The protective shell 64 can protect the cycloid size adjusting member 6 .

[0034] A lower adjusting rotating gear 50 is also provided in the cycloid shell 41. The lower adjusting rotating gear 50 is sleeved on the cycloid mover barrel 43 and is arranged below the upper adjusting rotating gear 49. A positioning top bead 51 and a positioning spring 52 are provided on the lower adjusting rotating gear 50. The positioning spring 52 is arranged below the positioning top bead 51. A plurality of angle positioning holes cooperating with the positioning top bead 51 are evenly arranged on the outer periphery of the lower end of the upper adjusting rotating gear 49, and the positioning top bead 51 is partially arranged in the angle positioning hole.

[0035] By setting the lower adjusting rotating gear 50, the upper and lower sides of the rotating adjusting end 63 can respectively engage with the upper adjusting rotating gear 49 and the lower adjusting rotating gear 50, which can effectively improve the stability of the pressing rotating adjusting part during the adjustment process. The rotating adjusting end 63 can drive the upper adjusting rotating gear 49 and the lower adjusting rotating gear 50 to rotate relative to each other.

[0036] In addition, by providing the positioning top bead 51 and the positioning spring 52, the wedge-shaped mirror mounting tube 47 can be further prevented from relative sliding during the rotation of the pendulum mover tube 43, thereby ensuring the stability of the position. When adjusting the size of the circular ring, the positioning top bead 51 and the positioning spring 52 are inserted into positioning holes of different angles to achieve adjustment of different gear sizes.

[0037] The position fixing member is a clamping cylinder 53, and the outer surface of the upper end of the oscillating rotor barrel 43 is provided with a connecting external thread (not shown), and the inner side of the clamping cylinder 53 is provided with a connecting internal thread that cooperates with the connecting external thread on the oscillating rotor barrel 43. The wedge mirror mounting cylinder 47 is provided with a gear mounting boss 471, and the gear mounting boss 471 is arranged above the upper adjustment rotating gear 49. The gear mounting boss 471 is provided with a gear mounting hole, and the gear mounting hole is provided with a gear locking screw 472, and the gear locking screw 472 can lock the upper adjustment rotating gear 49 On the gear mounting boss 471, a clamping boss 531 is arranged on the outer periphery of the upper end of the clamping cylinder 53, and the clamping boss 531 is arranged between the lower surface of the gear mounting boss 471 and the upper surface of the upper adjusting rotating gear 49, and the clamping cylinder 53 is arranged between the oscillating rotor barrel 43 and the inner ring of the upper adjusting rotating gear 49, and a limiting portion cooperating with the lower end of the lower adjusting rotating gear 50 is arranged on the oscillating rotor barrel 43, and the clamping cylinder 53 is arranged above the lower adjusting rotating gear 50, and the clamping cylinder 53 can press the lower adjusting rotating gear 50 on the limiting portion.

[0038] The clamping cylinder 53 can prevent the lower adjusting rotating gear 50 from sliding relative to each other during the rotation of the oscillating rotor barrel 43 , and can provide external force to the upper adjusting rotating gear 49 and the lower adjusting rotating gear 50 at the same time, thereby reducing the number of product components.

[0039] Obviously, for the structural design in which the position fixing part is a clamping cylinder 53, and the clamping cylinder 53 provides external force to the upper adjusting rotating gear 49 and the lower adjusting gear at the same time, other alternative structures can also be adopted. For example, an anti-slip layer is provided on the outer surface of the pendulum mover barrel 43, and the upper adjusting rotating gear 49 and the lower adjusting rotating gear 50 are sleeved on the anti-slip layer, which can provide a certain friction force to ensure that the gears will not slide relative to each other during the rotation of the pendulum mover barrel 43, and the effect of the above-mentioned scheme can also be achieved.

[0040] An anti-friction bearing 54 is also provided in the cycloid housing 41 , and the anti-friction bearing 54 is sleeved on the outer surface of the cycloid mover barrel 43 .

[0041] The anti-friction bearing 54 can effectively prevent the oscillating rotor barrel 43 from rubbing against the inner wall of the oscillating housing 41 and causing wear.

[0042] A bearing limiting step 431 cooperating with the lower end of the anti-friction bearing 54 is provided on the oscillating rotor barrel 43. The anti-friction bearing 54 is arranged below the lower adjusting rotating gear 50. The limiting portion is the upper end surface of the anti-friction bearing 54. The clamping cylinder 53 can position the anti-friction bearing 54 on the bearing limiting step 431.

[0043] By setting the bearing limiting step 431, the clamping cylinder 53 can simultaneously fix the vertical heights of the upper adjusting rotating gear 49, the lower adjusting rotating gear 50 and the anti-friction bearing 54, thereby ensuring that the positions of the components are more stable.

[0044] The novel edge sealing head structure also includes a first lens fixing elastic tube 55 and a second lens fixing elastic tube 56. The first lens fixing elastic tube 55 and the second lens fixing elastic tube 56 both include a fixing seat and a plurality of elastic rings. The plurality of elastic rings are stacked up and down. The elastic rings are connected to adjacent elastic rings by a plurality of connecting ribs, and the connecting ribs on the adjacent sides of the elastic rings are staggered with each other. The first lens fixing elastic tube 55 is fixedly arranged on the periphery of the upper surface of the first wedge-shaped mirror 44. The first lens fixing elastic tube 55 can fix the first wedge-shaped mirror 44 in the first lens mounting position. The second lens fixing elastic tube 56 is fixedly arranged on the periphery of the upper surface of the second wedge-shaped mirror 48. The second lens fixing elastic tube 56 can fix the second wedge-shaped mirror 48 in the wedge-shaped mirror mounting tube 47.

[0045] The arrangement of the first lens fixing elastic tube 55 and the second lens fixing elastic tube 56 can adapt to the structure of the first wedge-shaped mirror 44 and the second wedge-shaped mirror 48, better fit the wedge-shaped mirror, and ensure the stability of the position of the wedge-shaped mirror.

[0046] The first lens fixing elastic tube 55 and the second lens fixing elastic tube 56 are both made of copper. The copper material can effectively improve the heat dissipation level and ensure the service life of the first wedge-shaped mirror 44 and the second wedge-shaped mirror 48.

[0047] The novel edge banding head structure also includes a rotation speed regulating box 57 , which is fixedly mounted on the pendulum shell 41 . A controller is disposed in the rotation speed regulating box 57 , and a speed regulating knob 58 is disposed on the controller. The controller is electrically connected to the pendulum stator barrel 42 .

[0048] By setting the rotation speed regulating box 57, according to the different rotation speeds of the pendulum mover barrel 43, the shape of the light spot when it is emitted is changed. Without the action of the galvanometer module assembly, under the action of the rotation of the pendulum mover barrel 43, the trajectory of the light spot emission is a continuous circle. After adding the galvanometer module assembly, the trajectory is similar to the shape of the side of a spring, consisting of a pair of continuous circles. When the rotation speed is fast, the pitch of the spring-shaped light spot will become smaller, and when the rotation speed is slow, the pitch of the spring-shaped light spot will become larger, which can meet the scene usage requirements of different users. In conjunction with the galvanometer module assembly, multiple continuous circles will be paved into a straight line with a certain width. Compared with the traditional light spot composed of multiple points, the width of the straight line is wider and the glue layer melts more evenly.

[0049] The galvanometer module assembly includes a galvanometer module housing 21 and a galvanometer mounting housing 22 arranged on one side of the galvanometer module housing 21, a drive mounting seat 23 and a galvanometer assembly 24 are arranged in the galvanometer mounting housing 22, a galvanometer window 210 cooperating with the galvanometer assembly 24 is arranged on the galvanometer module housing 21, a galvanometer mounting channel running through the front and rear ends is arranged in the drive mounting seat 23, the galvanometer assembly 24 is arranged in the galvanometer mounting channel, the drive mounting seat 23 is fixed on the galvanometer module housing 21, and one end of the galvanometer assembly 24 passes through the galvanometer window 210 and is arranged in the galvanometer module housing 21.

[0050] The galvanometer assembly 24 includes a galvanometer motor, a lens clamp and a reflective lens. One end of the lens clamp is connected to the moving end of the driving motor, and the other end of the lens clamp is connected to the reflective lens. The galvanometer motor can adjust the reflection angle of the reflective lens.

[0051] By setting the galvanometer module assembly, the angle of the light emitted by the pendulum assembly can be adjusted and swung up and down, and the swing range is the processing width.

[0052] A focusing lens 25 is disposed on one side of the galvanometer module housing 21 close to the focusing protection component, and the focusing lens 25 can focus the light beam.

[0053] The focus protection assembly includes a focus protection mounting seat 31 and a focus protection drawer assembly 32. The focus protection drawer assembly 32 includes a drawer frame and a focus protection lens assembly arranged on the drawer frame.

[0054] The focusing protection mounting seat 31 includes a mounting seat front shell, a mounting seat rear shell and a laser head connecting piece 33. The mounting seat front shell and the mounting seat rear shell are fixedly connected. The mounting seat front shell and the mounting seat rear shell are provided with laser head connecting holes that cooperate with the laser head connecting piece 33. The laser head connecting piece 33 passes through the laser head connecting holes of the mounting seat front shell and the mounting seat rear shell in turn and is connected and fixed to the laser head. The laser head connecting piece 33 can fix the focusing protection mounting seat 31 on the laser head. The mounting seat front shell is provided with a light outlet, and the mounting seat rear shell is provided with a light inlet.

[0055] The focusing lens 25 can be effectively protected by the focusing protection component.

[0056] As can be seen from the above, the beneficial effects of the present invention are: adopting its mechanism can effectively solve the problem of uneven melting of the glue layer in the edge sealing head structure in the prior art. By using this product structure, there is an angle between the upper and lower surfaces of the first wedge mirror 44, and it rotates with the pendulum rotor barrel 43, so that the emitted light spot is ring-shaped, which effectively increases the area of ​​a single output light spot, and while melting the glue layer, it will also irradiate the plate, increasing the heating area, making the glue layer melt more evenly, which can meet the use needs of processing personnel and effectively improve the competitiveness of the enterprise.

[0057] The specific implementation modes described above are preferred implementation modes of the present invention, and are not intended to limit the specific implementation scope of the present invention.
