Example 1

[0029] Reference Figure 3~Figure 9 , which is the first embodiment of the present invention, provides a plastic laser welding machine, which includes a flip assembly 200, a clutch assembly 300 and a main assembly 100. The three can be combined to flip the plastic and then weld it after welding one side of the plastic.

[0030] The flip assembly 200 includes a flip box 201a, a closed door 201b, a first rack 201c, a first gear 201d, a second rack 201e, a translation block 201f and a reciprocating roller 201g. The closed door 201b is plugged into one side of the flip box 201a, and the closed door 201b and the flip box 201a are movably connected. The first rack 201c is fixed to one side of the closed door 201b, the first gear 201d is located on one side of the first rack 201c, the second rack 201e is arranged on one side of the first gear 201d, the translation block 201f is fixed to one side of the second rack 201e, the reciprocating roller 201g is plugged into one side of the translation block 201f, and the reciprocating roller 201g and the translation block 201f are movably connected.

[0031] There are four closed doors 201b, which are respectively arranged on both sides of the flip box 201a. There are four first racks 201c, which are respectively slidably connected to the two sides of the flip box 201a. There are two first gears 201d, which are respectively rotatably connected to the two sides of the flip box 201a through a rotating shaft. There are four second racks 201e, which are all slidably connected to the two sides of the flip box 201a. The first gear 201d is respectively engaged with the first rack 201c and the second rack 201e. There are two translation blocks 201f, which are both fixed on one side of the second rack 201e. A driving groove is opened on the reciprocating roller 201g, and a driving block is arranged in the translation block 201f. The driving groove is engaged with the driving block, and the rotation of the reciprocating roller 201g can drive the translation block 201f to rotate.

[0032] When the flip box 201a is in the initial position, the closed door 201b on one side is in an open state, and the closed door 201b on the other side is in a closed state. When the flip box 201a flips, it will drive the reciprocating roller 201g to rotate, and the rotation of the reciprocating roller 201g drives the translation block 201f to move, and the translation block 201f drives the second rack 201e to move. The second rack 201e is fixed to one side of the closed door 201b. The movement of the second rack 201e will drive the closed door 201b to move, and the second rack 201e will drive the second rack 201e to move. A gear 201d rotates, and the first gear 201d rotates to drive the first rack 201c to move. The movement of the first rack 201c will drive another closed door 201b to move, so that the two closed doors 201b move toward each other. At this time, the other set of closed doors 201b will move in the opposite direction. After the flip box 201a is flipped, the closed door 201b on the side below the laser welding head 101 is in an open state, and the closed door 201b on the other side is in a closed state, so that both sides of the plastic can be welded.

[0033] A clamping plate is provided in the flip box 201a, a moving rod is fixed on one side of the clamping plate, a return spring is fixed on one side of the moving rod, a supporting sleeve is sleeved on the outer side of the moving rod, the supporting sleeve is movably connected to the moving rod, and the supporting sleeve is fixed to the inner wall of the flip box 201a. When the plastic is placed in the flip box 201a, the clamping plate can be squeezed, and the moving rod will be driven to move at this time. The movement of the moving rod will apply a squeezing force to the return spring, and the rebound force of the return spring can drive the clamping plate to clamp the plastic, which is convenient for welding the plastic. After the plastic is placed in the flip box 201a, the closed door 201b closed at the bottom will support the plastic. After one side is welded, it is flipped to the other side. At this time, the closed door 201b on the other side will be opened, so as to facilitate welding of the other side of the plastic. After welding is completed, the plastic can be taken out.

[0034] The clutch assembly 300 is arranged on one side of the flip box 201a, and includes a first friction disk 301a, a second friction disk 301b, a drive frame 301c, a movable column 301d, a first spring 301e and a drive sleeve 301f. The first friction disk 301a is fixed on one side of the flip box 201a, the second friction disk 301b is located on one side of the first friction disk 301a, the drive frame 301c is sleeved on the outside of the second friction disk 301b, the drive frame 301c and the second friction disk 301b are movably connected, the movable column 301d is fixed on one side of the second friction disk 301b, the first spring 301e is sleeved on the outside of the movable column 301d, the drive sleeve 301f is sleeved on the outside of the movable column 301d, and the drive sleeve 301f and the movable column 301d are movably connected.

[0035] Friction pads are provided on one side of the first friction disk 301a and the second friction disk 301b to increase friction force. A blocking block is provided on the outer side of the movable column 301d. A slot corresponding to the blocking block is provided in the driving sleeve 301f.

One end of the first spring 301e is fixed to one side of the movable column 301d, and the other end is fixed to one side of the driving sleeve 301f.

[0036] The second friction disc 301b can be driven to move to contact the first friction disc 301a by moving the driving frame 301c, and the driving frame 301c can apply a pulling force to the first spring 301e when moving. After the second friction disc 301b is engaged with the first friction disc 301a, the rotation of the driving sleeve 301f can drive the moving column 301d to rotate, and the rotation of the moving column 301d drives the second friction disc 301b to rotate, and the rotation of the second friction disc 301b can drive the first friction disc 301a rotates, and the rotation of the first friction disk 301a can drive the flip box 201a to rotate. When processing, there is no need to flip the flip box 201a. When only one side of the plastic is welded, the limit of the driving frame 301c is released, and then the rebound force of the first spring 301e will drive the second friction disk 301b to separate from the first friction disk 301a. When the second friction disk 301b rotates, it will not drive the first friction disk 301a to rotate, thereby preventing the flip box 201a from rotating. Example 2

At this time, an extrusion force can be applied to the second spring 202b, and the rebound force of the second spring 202b can make the closed door 201b return to its original position, so as to support the closed door 201b and prevent the closed door 201b from deviating when moving.

[0040] Specifically, a positioning block 202c is sleeved on the outer side of the reciprocating roller 201g, the positioning block 202c and the reciprocating roller 201g are movably connected, the positioning block 202c is fixed to the top of the flip box 201a, a first pulley 202d is fixed at one end of the reciprocating roller 201g, a belt 202e is sleeved on the outer side of the first pulley 202d, and a second pulley 202f is arranged inside the belt 202e.

[0041] There are two positioning blocks 202c, both of which are sleeved on the outside of the reciprocating roller 201g. The positioning block 202c is rotatably connected to the reciprocating roller 201g through a rotating shaft. The setting of the positioning block 202c can support the reciprocating roller 201g to prevent the reciprocating roller 201g from deviating. The rotation of the second pulley 202f can drive the belt 202e to rotate, and the rotation of the belt 202e will drive the first pulley 202d to rotate. The rotation of the first pulley 202d can drive the reciprocating roller 201g to rotate. The number of the first pulley 202d, the belt 202e and the second pulley 202f are each two, and they are respectively set on both sides of the flip box 201a.

When the flip box 201a rotates, it will drive the rotating rod 202h to rotate, and the rotation of the rotating rod 202h will drive the tooth groove X above to rotate. The engagement of the tooth groove X with the second gear 202g can make the two second gears 202g rotate, and the rotation of the second gear 202g can drive the second pulley 202f to rotate. The second gears 202g are respectively arranged on both sides of the rotating rod 202h. When the rotating rod 202h rotates, it will drive the two second gears 202g to rotate in different directions, and the driving groove on the reciprocating roller 201g is also set to the corresponding direction.

[0045] The tooth frame 302a is provided with inclined tooth grooves, and the clamping block 302c is set as an inclined surface. When the laser welding head 101 descends to weld the plastic, it will drive the driving rod 302e to rotate, and the rotation of the driving rod 302e will drive the turntable 302b to rotate, and the clamping block 302c in the turntable 302b will rotate. At this time, the clamping block 302c will be squeezed by the inclined tooth groove on the tooth frame 302a. When squeezing the clamping block 302c, an extrusion force can be applied to the third spring 302d. When the clamping block 302c moves to the bottom of the next inclined tooth groove, the rebound force of the third spring 302d can make the clamping block 302c re-align with the inclined surface The teeth and grooves are engaged, and the laser welding head 101 will not drive the tooth frame 302a to rotate when it descends. When the laser welding head 101 rises, it will drive the turntable 302b to reverse, and the reversal of the turntable 302b can drive the clamping block 302c to reverse.

The moving frame 102 is hinged to one end of the driving rod 302e. When the laser welding head 101 moves, it will drive the driving rod 302e to move, and the movement of the driving rod 302e can drive the turntable 302b to rotate.

[0046] Specifically, a positioning plate 302f is sleeved on the outer side of the driving sleeve 301f, and the positioning plate 302f is rotatably connected to the driving sleeve 301f via a rotating shaft.

[0047] The positioning plate 302f is fixed to the top of the workbench 105. The positioning plate 302f can be used to support the drive sleeve 301f to prevent the drive sleeve 301f from shifting. When the first friction disk 301a and the second friction disk 301b need to be engaged, the extrusion bar 302h is moved, and the extrusion bar 302h can squeeze the inclined surface block 302g to make it move. The movement of the inclined surface block 302g can drive the drive frame 301c to move, so that the first friction disk 301a and the second friction disk 301b can be engaged. A baffle is provided at one end of the inclined surface block 302g to limit the extrusion bar 302h to prevent the extrusion bar 302h from moving excessively and falling off the inclined surface block 302g. Example 3

[0048] Reference Figure 1 to Figure 9 , which is the third embodiment of the present invention, and is based on the first two embodiments.

Pulling the moving handle 302m can drive the pull rod 302k to move, so that the first friction disk 301a and the second friction disk 301b are engaged. In order to prevent the first friction disk 301a and the second friction disk 301b from being separated by the rebound force of the first spring 301e, the moving handle 302m is flipped to engage with the limiting groove provided on the limiting block 302n, so that the pull rod 302k can be limited.

[0056] The laser welding head 101 is used to focus and guide the laser beam to the plastic part that needs to be welded, so that the plastic can be welded. By starting the cylinder 104, the cylinder 104 can drive the moving frame 102 to move, and the movement of the moving frame 102 will drive the laser welding head 101 to move, so that the laser welding head 101 moves to the top of the flip box 201a, so that the plastic can be welded.

The force can make the clamping block 302c engage with the inclined tooth groove again, and in this reciprocating manner, the laser welding head 101 will not drive the tooth frame 302a to rotate when it descends. After the welding is completed, the laser welding head 101 will drive the turntable 302b to reverse when it rises, and the reversal of the turntable 302b can drive the clamping block 302c to reverse. At this time, the inclined tooth groove on the tooth frame 302a can be squeezed to make it rotate, and the rotation of the tooth frame 302a can drive the drive sleeve 301f to rotate, and the rotation of the drive sleeve 301f can drive the movable column 301d to rotate, and the rotation of the movable column 301d drives the second friction disk 301b to rotate, and the rotation of the second friction disk 301b can drive the first friction disk 301a to rotate, and the rotation of the first friction disk 301a can drive the flip box 201a to rotate.

The meshing of the tooth groove X with the second gear 202g can make the two second gears 202g rotate. The rotation of the second gear 202g can drive the second pulley 202f to rotate. The rotation of the second pulley 202f can drive the belt 202e to rotate. The rotation of the belt 202e will drive the first pulley 202d to rotate. The rotation of the first pulley 202d can drive the reciprocating roller 201g to rotate. The rotation of the reciprocating roller 201g will drive the translation block 201f to move. The translation block 201f drives The second rack 201e is driven to move, and the movement of the second rack 201e will drive the closed door 201b to move. At the same time, the second rack 201e will drive the first gear 201d to rotate, and the rotation of the first gear 201d will drive the first rack 201c to move. The movement of the first rack 201c will drive the other closed door 201b to move, so that the two closed doors 201b move toward each other. At this time, the other set of closed doors 201b will move in the opposite direction. After the flip box 201a is flipped, the closed door 201b on the side below the laser welding head 101 is in an open state, and the closed door 201b on the other side is in a closed state, so that both sides of the plastic can be welded.

[0060] When the flip box 201a does not need to be flipped during processing and only one side of the plastic is welded, the movable handle 302m is pushed with force to separate the movable handle 302m from the limit groove provided on the limit block 302n, and then the rebound force of the first spring 301e drives the second friction disk 301b to separate from the first friction disk 301a. When the second friction disk 301b rotates, it will not drive the first friction disk 301a to rotate, thereby preventing the flip box 201a from rotating.
