[0058] Specifically, when the processing platform of the existing engraving and milling machine is used, when it is necessary to engrave and mill the acrylic glass, the acrylic glass is placed on the placement plate 27, and then the engraving and milling cutter head 35 is used to engrave and mill the acrylic glass. After the engraving and milling are completed, the workers manually remove the acrylic glass. In some cases, the number of acrylic glasses that need to be engraved and milled is large, and the same batch of acrylic glasses that have been engraved and milled need to follow the conveyor belt to enter the next process for processing, such as labeling, packaging, etc., and it is laborious and labor-intensive for the workers to frequently manually remove the acrylic glass that has been engraved and milled from the placement plate. In addition, in general, in order to improve the processing efficiency of the acrylic glass in the next process, the acrylic glass needs to be kept neat on the conveyor belt. When the workers place the acrylic glass on the conveyor belt, it may be messy, which is not conducive to the next process. It is also laborious to manually organize the acrylic glass.

[0059] Therefore, in order to solve the above problems, when the present embodiment is used, the entire engraving and milling table is arranged on one side of the conveyor belt for conveying the acrylic glass after engraving and milling to the next process. When the acrylic glass is clamped on the placement plate 27, the motor 5 25 can drive the threaded rod 3 24 to rotate, and the motor 8 36 can drive the threaded rod 5 37 to rotate, so that the engraving and milling cutter head 35 is displaced horizontally and vertically. At the same time, the motor 7 32 can drive the threaded rod 4 28 to rotate, so that the slider 13 slides on the workbench 2, so that the position of the engraving and milling cutter head 35 above the acrylic glass can be adjusted, and the acrylic glass can be engraved and milled by the engraving and milling cutter head 35. This engraving and milling process is a prior art and will not be described in detail.

[0060] When a piece of acrylic glass is engraved and milled, the engraving and milling cutter head 35 is driven away from the acrylic glass, and then the slider 13 is driven to slide again to move the placement plate 27 toward one end of the workbench 2, and then the placement plate 27 is rotated by the motor 6 31 to tilt the placement plate 27 and fit one end of the blanking plate 3, and then the motor 4 21 is used to drive the threaded rod 22 to rotate to slide the slide plate 19 from left to right, so that the frame 4 can be moved until the end of one side of the discharge plate 7 is aligned with the end of the blanking plate 3 up and down. At this time, the positioning plate 33 is driven to release the acrylic glass, and the acrylic glass can fall onto the blanking plate 3 under the action of gravity, and slide onto the discharge plate 7 through the blanking plate 3. Since the discharge plate 7 is set inclined, the end of the acrylic glass will be One end of the discharge plate 7 is blocked and fits with one end of the discharge plate 7, and then the above operation is repeated. As multiple discharge plates 7 are moved out from the bottom of the workbench 2, multiple acrylic glasses are arranged horizontally at the same angle and placed on multiple discharge plates 7, and the discharge plates 7 are above the conveyor belt. Then, the electric push rods 1 5 on both sides are used to simultaneously drive the multiple adjustment blocks 11 on both sides to approach each other, and the acrylic glass on the discharge plate 7 is clamped by the multiple adjustment blocks 11. At this time, the motor 2 14 can be used to drive the threaded rod 1 16 to rotate, so that the discharge plate 7 moves horizontally until the acrylic glass is separated from the discharge plate 7. At this time, according to the height of the conveyor belt, the motor 3 20 is used to drive the connecting rod 1 17 and the connecting rod 2 18 to rotate, so that the frame 4 can be lowered until the acrylic glass clamped by the adjustment block 11 The acrylic glass is brought close to the conveyor belt, and then the multiple adjustment blocks 11 are driven away from the acrylic glass, so that the multiple acrylic glasses can be uniformly dropped onto the conveyor belt and follow the conveyor belt to enter the next process, thereby eliminating the need for workers to manually remove the acrylic glass that has been engraved and milled from the placement plate 27 frequently, which is more convenient and labor-saving. In addition, the acrylic glasses on the conveyor belt are neatly arranged, which is conducive to the next process. In addition, when multiple acrylic glasses are placed on the conveyor belt, adjacent acrylic glasses partially overlap. Compared with the method of placing multiple acrylic glasses separately and flatly, this placement method can reduce the horizontal placement space of the conveyor belt occupied by multiple acrylic glasses to a certain extent. At the same time, it also shortens the distance between the acrylic glasses at both ends, so that the same The batches of acrylic glass can reach the processing area more quickly, which is beneficial to improving the subsequent processing efficiency. Moreover, compared with the placement method of making multiple acrylic glasses stand up, fit or overlap, although this method further reduces the lateral placement space of the acrylic glass, the acrylic glasses placed upright and overlapped are easy to fall over, and the acrylic glasses block each other, which is not conducive to labeling and other operations on the acrylic glass surface. Moreover, since the acrylic glass that has been engraved and milled is first placed independently on the discharge plate 7, the worker can more easily check the engraving and milling quality of each acrylic glass before the acrylic glass is transferred to the conveyor belt, so as to avoid the acrylic glass with poor engraving and milling quality from flowing into the subsequent processing steps, which is beneficial to improving the inspection efficiency.

[0061] In addition, since the acrylic glass can only be moved to the discharge plate 7 after passing through the placement plate 27 and the unloading plate 3, and contacts with the end of the discharge plate 7, and the surface of some acrylic glass may be relatively rough, when the acrylic glass slides down, it may be stuck on the placement plate 27, the unloading plate 3, and the surface of the discharge plate 7 due to friction, and cannot contact with the end of the discharge plate 7, affecting the unloading work. Therefore, in order to avoid this problem, after the placement plate 27 is tilted, the electric push rod 38 can be used to drive the push plate 40 to move, so that the push plate 40 moves along the placement plate 27, the unloading plate 3, and the surface of the discharge plate 7 to push the acrylic glass and promote the sliding of the acrylic glass until the end of the acrylic glass contacts with the end of the discharge plate 7, thereby avoiding the situation that the acrylic glass is stuck on the placement plate 27, the unloading plate 3, and the surface of the discharge plate 7 due to friction when sliding down, and cannot contact with the end of the discharge plate 7, further ensuring the smooth unloading work;

[0062] Although the above method can be used to transfer multiple acrylic glasses to the conveyor belt, when the adjustment block 11 loosens the acrylic glass, the acrylic glass will vibrate to a certain extent due to mutual collision, which may cause the acrylic glass to deviate or even become messy, making the edges of multiple acrylic glasses non-aligned, thereby affecting the subsequent processing steps. Therefore, in order to avoid this situation, after the adjustment block 11 loosens the acrylic glass, the motor 10 is used to drive the worm 12 to rotate, and the worm 12 uses the multiple worm teeth on its surface to make the multiple worm wheels 9 rotate synchronously, so that the multiple adjustment blocks 11 can be moved to the conveyor belt. 1 rotates simultaneously until the adjusting block 11 is parallel to the upper surface of the conveyor belt. At this time, the adjusting block 11 is driven down to make the lower end surface of the adjusting block 11 fit with the upper surface of the conveyor belt, and then the adjusting block 11 is driven again to approach the acrylic glass on the conveyor belt, and the adjusting blocks 11 on both sides can be used to push the edge of the acrylic glass until the edges of multiple acrylic glasses are aligned, thereby avoiding the acrylic glass from being offset or even messy due to collision when the adjusting block 11 releases the acrylic glass, further ensuring the neatness of multiple acrylic glasses on the conveyor belt, which is beneficial to the subsequent processing procedures.

[0063] Working principle: Place the acrylic glass to be engraved and milled on the upper end of the placement plate 27, and then drive the positioning plates 33 on both sides to move and approach each other through the electric push rods 29 on both sides, until they are in contact with both sides of the acrylic glass, so that the acrylic glass can be clamped, thereby ensuring the stability of the acrylic glass during engraving and milling. The motor 5 25 drives the threaded rod 3 24 to rotate, and the motor 8 36 drives the threaded rod 5 37 to rotate, so that the engraving and milling cutter head 35 is displaced horizontally and vertically. At the same time, the motor 7 32 can drive the threaded rod 4 28 to rotate, so that the slider 13 slides on the workbench 2, so that the position of the engraving and milling cutter head 35 above the acrylic glass can be adjusted, and the acrylic glass can be engraved and milled by the engraving and milling cutter head 35. This engraving and milling process is a prior art and will not be described in detail.When a piece of acrylic glass is engraved and milled, the engraving and milling cutter head 35 is driven away from the acrylic glass, and then the slider 13 is driven to slide again to move the placement plate 27 toward one end of the workbench 2, and then the placement plate 27 is rotated by the motor 6 31 to tilt the placement plate 27 and fit one end of the blanking plate 3, and then the motor 4 21 is used to drive the threaded rod 22 to rotate to slide the slide plate 19 from left to right, so that the frame 4 can be moved until the end of one side of the discharge plate 7 is aligned with the end of the blanking plate 3 up and down. At this time, the positioning plate 33 is driven to release the acrylic glass, and the acrylic glass can fall onto the blanking plate 3 under the action of gravity, and slide onto the discharge plate 7 through the blanking plate 3. Since the discharge plate 7 is set inclined, the end of the acrylic glass will be One end of the discharge plate 7 is blocked and fits with one end of the discharge plate 7, and then the above operation is repeated. As multiple discharge plates 7 are moved out from the bottom of the workbench 2, multiple acrylic glasses are arranged horizontally at the same angle and placed on multiple discharge plates 7, and the discharge plates 7 are above the conveyor belt. Then, the electric push rods 1 5 on both sides are used to simultaneously drive the multiple adjustment blocks 11 on both sides to approach each other, and the acrylic glass on the discharge plate 7 is clamped by the multiple adjustment blocks 11. At this time, the motor 2 14 can be used to drive the threaded rod 1 16 to rotate, so that the discharge plate 7 moves horizontally until the acrylic glass is separated from the discharge plate 7. At this time, according to the height of the conveyor belt, the motor 3 20 is used to drive the connecting rod 1 17 and the connecting rod 2 18 to rotate, so that the frame 4 can be lowered until the acrylic glass clamped by the adjustment block 11 The acrylic glass is brought close to the conveyor belt, and then the multiple adjustment blocks 11 are driven away from the acrylic glass, so that the multiple acrylic glasses can be uniformly dropped onto the conveyor belt and follow the conveyor belt to enter the next process, thereby eliminating the need for workers to manually remove the acrylic glass that has been engraved and milled from the placement plate 27 frequently, which is more convenient and labor-saving. In addition, the acrylic glasses on the conveyor belt are neatly arranged, which is conducive to the next process. In addition, when multiple acrylic glasses are placed on the conveyor belt, adjacent acrylic glasses partially overlap. Compared with the method of placing multiple acrylic glasses separately and flatly, this placement method can reduce the horizontal placement space of the conveyor belt occupied by multiple acrylic glasses to a certain extent. At the same time, it also shortens the distance between the acrylic glasses at both ends, so that the same The batches of acrylic glass can reach the processing area more quickly, which is beneficial to improving the subsequent processing efficiency. Moreover, compared with the placement method of making multiple acrylic glasses stand up, fit or overlap, although this method further reduces the lateral placement space of the acrylic glass, the acrylic glasses placed upright and overlapped are easy to fall over, and the acrylic glasses block each other, which is not conducive to labeling and other operations on the acrylic glass surface. Moreover, since the acrylic glass that has been engraved and milled is first placed independently on the discharge plate 7, the worker can more easily check the engraving and milling quality of each acrylic glass before the acrylic glass is transferred to the conveyor belt, so as to avoid the acrylic glass with poor engraving and milling quality from flowing into the subsequent processing steps, which is beneficial to improving the inspection efficiency.Furthermore, since the acrylic glass can only be moved to the discharge plate 7 after passing through the placement plate 27 and the unloading plate 3, and contacts with the end of the discharge plate 7, and the surface of some acrylic glass may be relatively rough, when the acrylic glass slides, it may be stuck on the placement plate 27, the unloading plate 3, and the surface of the discharge plate 7 due to friction, and cannot contact with the end of the discharge plate 7, affecting the unloading work. Therefore, in order to avoid this problem, after the placement plate 27 is tilted, the electric push rod 38 can be used to drive the push plate 40 to move, so that the push plate 40 moves along the placement plate 27. The surfaces of the placing plate 27, the unloading plate 3 and the discharge plate 7 move to push the acrylic glass and promote the sliding of the acrylic glass until the end of the acrylic glass contacts the end of the discharge plate 7, thereby avoiding the situation that the acrylic glass is stuck on the surfaces of the placing plate 27, the unloading plate 3 and the discharge plate 7 due to friction when sliding down and cannot contact the end of the discharge plate 7, further ensuring the smooth progress of the unloading work; although multiple acrylic glasses can be transferred to the conveyor belt in the above manner, when the adjusting block 11 loosens the acrylic glass, the acrylic glass The glass will vibrate to a certain extent due to mutual collision, which may cause the acrylic glass to deviate or even become messy, making the edges of multiple acrylic glasses non-aligned, thereby affecting the subsequent processing steps. Therefore, in order to avoid this situation, after the adjustment block 11 loosens the acrylic glass, the motor 10 is used to drive the worm 12 to rotate, and the worm 12 uses the multiple worm teeth on its surface to make the multiple worm wheels 9 rotate synchronously, so that the multiple adjustment blocks 11 can rotate at the same time until the adjustment block 11 is parallel to the upper surface of the conveyor belt. At this time, the adjusting block 11 is driven down to make the lower end surface of the adjusting block 11 fit with the upper surface of the conveyor belt, and then the adjusting block 11 is driven again to approach the acrylic glass on the conveyor belt, and the edges of the acrylic glass can be pushed by the adjusting blocks 11 on both sides until the edges of multiple acrylic glasses are aligned, thereby avoiding the acrylic glass from being offset or even messy due to mutual collision when the adjusting block 11 releases the acrylic glass, further ensuring the neatness of multiple acrylic glasses on the conveyor belt, which is conducive to the subsequent processing procedures. ;
