The barcode scanner is detachably connected to both barcode scanner mounting positions. The base also includes a laser processing mechanism, a blocking mounting position, and a lifting and positioning mechanism. The laser processing mechanism is located above the second conveyor belt. The two blocking mounting positions are respectively located at the two conveying inlets of the second conveyor belt. Each blocking mounting position is equipped with a detachable lifting blocking mechanism. The lifting blocking mechanism and the blocking mounting position have two installation methods, one in a forward direction and one in a reverse direction. Switching between the two installation methods of the lifting blocking mechanism changes its blocking direction. The lifting and positioning mechanism is located between the two lifting blocking mechanisms.

[0006] In one embodiment, the first conveyor belt, the second conveyor belt, and the third conveyor belt are all structures of two parallel and separate conveyor belts facing each other.

[0007] In one embodiment, the first conveyor belt, the second conveyor belt, and the third conveyor belt each include a pulley assembly, a conveyor belt, and a conveyor motor; the two pulley assemblies are arranged separately and opposite to each other; the two conveyor belts are respectively tensioned outside the two pulley assemblies; the two conveyor motors are respectively used to drive the two pulley assemblies to rotate, and both conveyor motors are motors that can switch between forward and reverse rotation.

[0008] In one embodiment, both the lifting blocking mechanism and the lifting positioning mechanism are located between the two conveyor belts of the second conveyor belt.

[0009] In one embodiment, the lifting and blocking mechanism includes a lifting control component and a blocking block disposed on the lifting part of the lifting control component; the lifting control component is detachably connected to the base, and the lifting control component is used to control the lifting and lowering movement of the blocking block; the blocking surface of the blocking block on the conveyed material is oriented opposite to the conveying direction of the conveyed material.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] This utility model provides a belt-mounted bidirectional transmission laser engraving device, the implementation of which is as follows: Figure 1 ,as well as Figures 3 to 6 As shown, the system includes a base 10 and a first conveyor belt 21, a second conveyor belt 22 and a third conveyor belt 23 arranged sequentially on the base 10 along a straight line. This system can switch between four conveying modes for the material 70.

[0033] The first conveyor belt 21, the second conveyor belt 22, and the third conveyor belt 23 are used to convey the material 70, so as to realize the feeding and discharging of the material 70. In order to enable this embodiment to switch the conveying direction of the material 70 as needed, the first conveyor belt 21, the second conveyor belt 22, and the third conveyor belt 23 are all designed to have a reversible conveying direction.

[0034] Therefore, in order to realize the above functions of the first conveyor belt 21, the second conveyor belt 22 and the third conveyor belt 23, it is necessary to realize the support of the conveyed material 70 by the first conveyor belt 21, the second conveyor belt 22 and the third conveyor belt 23, as well as the switching of the conveying direction.

[0035] Among them, in order to achieve the supporting and conveying of the conveyed material 70, such as Figure 1 ,as well as Figures 3 to 6 As shown, in this embodiment, the first conveyor belt 21, the second conveyor belt 22, and the third conveyor belt 23 are all configured as two parallel and separate conveyor belts 25. Therefore, when it is necessary to transport the material 70, it is only necessary to place the material 70 on the two conveyor belts 25, and the synchronous rotation of the two conveyor belts 25 can realize the transport of the material 70 to the designated work station.

[0036] In addition, to achieve the switching of conveying direction, such as Figure 1As shown, in this embodiment, the first conveyor belt 21, the second conveyor belt 22, and the third conveyor belt 23 each include a pulley assembly 24, a conveyor belt 25, and a conveyor motor 26; the two pulley assemblies 24 are arranged separately and opposite to each other; the two conveyor belts 25 are respectively tensioned outside the two pulley assemblies 24; the two conveyor motors 26 are respectively used to drive the two pulley assemblies 24 to rotate, and both conveyor motors 26 are motors that can switch between forward and reverse rotation.

[0037] After adopting the above configuration, the output shaft of the conveyor motor 26 only needs to be connected to one of the pulleys in the pulley group 24. If the conveyor motor 26 rotates in the forward direction, it can drive the conveyor belt 25 to rotate in the forward direction. If the conveyor motor 26 is switched to the reverse direction, it can drive the conveyor belt 25 to rotate in the reverse direction.

[0038] Obviously, the conveyor motors 26 of the first conveyor belt 21, the second conveyor belt 22, and the third conveyor belt 23 are all independent of each other, so the forward and reverse conveying directions of the first conveyor belt 21, the second conveyor belt 22, and the third conveyor belt 23 can be switched independently as needed.

[0039] Similarly, the conveyor motors 26 of the first conveyor belt 21, the second conveyor belt 22, and the third conveyor belt 23 can be set to different speeds as needed, so that the first conveyor belt 21, the second conveyor belt 22, and the third conveyor belt 23 are all structures with independently adjustable conveying speeds, meeting the usage needs of more different situations.

[0040] Furthermore, in application, one of the first conveyor belt 21 and the third conveyor belt 23 will serve as the feeding point, and after feeding, the conveyed material 70 needs to be scanned. Figure 1 As shown, this embodiment also provides barcode scanner mounting positions 27 on both the first conveyor belt 21 and the third conveyor belt 23. One of the two barcode scanner mounting positions 27 is equipped with a barcode scanner 30, and the barcode scanner 30 is detachably connected to both barcode scanner mounting positions 27.

[0041] Therefore, when the first conveyor belt 21 is used as the feeding position for conveying material 70, the barcode scanner 30 can be installed on the barcode scanner mounting position 27 of the first conveyor belt 21; if it is necessary to change the third conveyor belt 23 to be used as the feeding position for conveying material 70, simply remove the barcode scanner 30 from the first conveyor belt 21 and install it on the barcode scanner mounting position 27 of the third conveyor belt 23.

[0042] It should be noted that, in order to avoid the barcode scanner 30 obstructing the conveying of the material 70, this embodiment sets the barcode scanner 30 to a suspended installation to ensure that the barcode scanner 30 can always be positioned above the material 70. Specifically, as shown below... Figure 1 ,as well as Figures 3 to 6As shown, the barcode scanner 30 is connected to a support bracket 31. The support bracket 31 and the two barcode scanner mounting positions 27 are detachably connected, and the support bracket 31 suspends the barcode scanner 30 above the first conveyor belt 21 or the third conveyor belt 23.

[0043] It should also be noted that various different implementation methods can be used to achieve a detachable connection between the support bracket 31 and the code gun mounting position 27, such as pin connection, latch connection, snap-on connection, etc. In this embodiment, the support bracket 31 and the two code gun mounting positions 27 are all connected by bolts and screw holes. This connection method is simple, reliable and quick to operate, and effectively meets the usage requirements of setting the two as a detachable connection.

[0044] Regarding the base 10, it is mainly used for the installation and arrangement of various components, such as... Figure 1 As shown, in this embodiment, the base 10 is also provided with a laser processing mechanism 40, a blocking mounting position 11, and a lifting and positioning mechanism 50.

[0045] In this embodiment, the laser processing mechanism 40 is positioned above the second conveyor belt 22. Therefore, when the conveyed material 70 is delivered to the position opposite to the laser processing mechanism 40 on the second conveyor belt 22, the laser processing mechanism 40 can be used to perform laser processing on the conveyed material 70.

[0046] The function of the blocking mounting position 11 is to install corresponding components to achieve positioning of the conveyed material 70 after it arrives at the corresponding workstation. Therefore, to achieve this purpose, such as... Figure 1 ,as well as Figures 3 to 6 As shown, in this embodiment, two blocking mounting positions 11 are respectively located at the two conveying ports of the second conveyor belt 22. Each of the two blocking mounting positions 11 is equipped with a detachable lifting blocking mechanism 60, and the lifting blocking mechanism 60 and the lifting positioning mechanism 50 are both located between the two conveyor belts 25 of the second conveyor belt 22. The lifting blocking mechanism 60 and the blocking mounting position 11 have two installation methods in opposite directions, so that the two installation methods of the lifting blocking mechanism 60 can be switched to change its blocking direction.

[0047] After adopting the above configuration, one lifting blocking mechanism 60 is arranged adjacent to the first conveyor belt 21, and another lifting blocking mechanism 60 is arranged adjacent to the third conveyor belt 23. If it is necessary to block the conveyed material 70 from being conveyed towards the third conveyor belt 23, the blocking direction of the lifting blocking mechanism 60 can be aligned with the conveying direction of the first conveyor belt 21. Once the conveyed material 70 moves to the position of the lifting blocking mechanism 60, the lifting blocking mechanism 60 will come into contact with the conveyed material 70, thereby realizing the positioning of the conveyed material 70.

[0048] Similarly, if it is necessary to block the conveying material 70 from being conveyed in the direction of the first conveyor belt 21, the lifting blocking mechanism 60 can be removed from the base 10 and the installation direction of the lifting blocking mechanism 60 can be reversed so that the blocking direction of the lifting blocking mechanism 60 is aligned with the conveying direction of the third conveyor belt 23. Once the conveying material 70 moves to the position of the lifting blocking mechanism 60, the lifting blocking mechanism 60 will also come into contact with the conveying material 70, thereby realizing the positioning of the conveying position of the conveying material 70.

[0049] It should be noted that there are two workstations where the conveying material 70 needs to be positioned: one is the barcode scanning workstation, and the other is the laser processing workstation. Therefore, this embodiment sets up two lifting and blocking mechanisms 60 in order to accurately position the conveying material 70 at the above two workstations.

[0050] However, during the process of conveying the material from the barcode scanning station to the laser processing station, the lifting and blocking mechanism 60 used to position the conveyed material 70 at the barcode scanning station will cause obstruction to the conveying. Therefore, the lifting and blocking mechanism 60 can eliminate the obstruction to the conveyed material 70 by lowering at this time, so as to ensure that the conveyed material 70 can smoothly reach the next lifting and blocking mechanism 60.

[0051] When it is necessary to use the lifting blocking mechanism 60 to block the conveyed material 70 in order to position the conveyed material 70, simply raise the lifting blocking mechanism 60 so that it can come into contact with the conveyed material 70, and the position of the conveyed material 70 can be achieved.

[0052] Therefore, in order to realize the lifting function of the lifting blocking mechanism 60, such as Figures 1 to 6 As shown, this embodiment provides a lifting and blocking mechanism 60 including a lifting control component 61 and a blocking block 62 disposed on the lifting part of the lifting control component 61; the lifting control component 61 is detachably connected to the base 10, and the lifting control component 61 is used to control the lifting and lowering movement of the blocking block 62; the blocking surface of the blocking block 62 on the conveying material 70 is opposite to the conveying direction of the conveying material 70.

[0053] For example, the lifting control component 61 mentioned above can be a cylinder, so it can achieve the lifting control of the blocking block 62 through its telescopic movement. Specifically, if it is necessary to position the conveying material 70, the lifting control component 61 can be used to raise the blocking block 62 so that the blocking block 62 is placed on the conveying path of the conveying material 70. So once the conveying material 70 reaches the position of the blocking block 62, the blocking block 62 will come into contact with the conveying material 70, thereby achieving the positioning of the conveying position of the conveying material 70.

[0054] When it is necessary to remove the obstruction of the blocking block 62 on the conveying material 70, simply use the lifting control component 61 to control the blocking block 62 to descend until the blocking block 62 completely leaves the conveying path of the conveying material 70, and the conveying material 70 can continue to be conveyed to the next conveying position.

[0055] It should also be noted that various different implementation methods can be adopted to achieve a detachable connection between the lifting control component 61 and the base 10, such as pin connection, latch connection, snap-on connection, etc. In this embodiment, the lifting control component 61 and the base 10 are connected by bolts and screw holes. This connection method is simple, reliable and quick to operate, and effectively meets the usage requirements of setting the two to a detachable connection.

[0056] The function of the lifting and positioning mechanism 50 is to lift the material 70 to the laser processing mechanism 40. Therefore, to achieve this purpose, as follows... Figure 1 ,as well as Figures 3 to 6 As shown, in this embodiment, the lifting and positioning mechanism 50 is set between the two lifting and blocking mechanisms 60 to ensure that after the conveyed material 70 is positioned at the barcode scanning station by one lifting and blocking mechanism 60, it will be positioned at the laser processing station by the other lifting and blocking mechanism 60. This allows the lifting and positioning mechanism 50 to adjust the conveyed material 70 to the correct placement state, and then lift the conveyed material 70 to the laser processing mechanism 40 for processing.

[0057] In order to achieve the lifting operation of the lifting and positioning mechanism 50 on the conveying material 70, such as Figure 1 and Figure 2 As shown, the lifting and positioning mechanism 50 in this embodiment includes a lifting control component 51 and a lifting platform 52 disposed on the lifting part of the lifting control component 51; the lifting control component 51 is used to control the lifting platform 52 to perform lifting and lowering movements; the lifting platform 52 is opposite to the laser processing part of the laser processing mechanism 40.

[0058] For example, the lifting control component 51 mentioned above can be a cylinder, so it can realize the lifting control of the lifting platform 52 through its telescopic movement. Specifically, if it is necessary to lift the conveyed material 70 to the laser processing mechanism 40 for processing, the lifting control component 51 can be used to raise the lifting platform 52 so as to send the conveyed material 70 on the lifting platform 52 to the processing position of the laser processing mechanism 40. After processing is completed, the lifting control component 51 controls the lifting platform 52 to descend so that the processed conveyed material 70 can be sent to the next work station.

[0059] To better explain the above embodiments, the following description will be based on four specific application scenarios.

[0060] Scene 1 (Enter from left, exit from right)

[0061] like Figure 3 As shown, the first conveyor belt 21, the second conveyor belt 22, and the third conveyor belt 23 are all set to convey from left to right, and the blocking surfaces of the two lifting blocking mechanisms 60 are both arranged facing left. At this time, the conveyed material 70 will be placed on the first conveyor belt 21, and both lifting blocking mechanisms 60 are in the raised state. So when the first conveyor belt 21 conveys the conveyed material 70 to the right, once the conveyed material 70 comes into contact with the lifting blocking mechanism 60 on the left, it indicates that the conveyed material 70 has reached the barcode scanning station, and the barcode scanner 30 can be used to scan the conveyed material 70.

[0062] After the scanning operation is completed, the lifting and blocking mechanism 60 on the left is lowered, and the first conveyor belt 21 and the second conveyor belt 22 are used to send the conveyed material 70 to the lifting and positioning mechanism 50 until the conveyed material 70 comes into contact with the lifting and blocking mechanism 60 on the right. This indicates that the conveyed material 70 has reached the laser processing station. At this time, the lifting and positioning mechanism 50 can be used to lift the conveyed material 70 upward for processing.

[0063] After the laser processing is completed, the lifting and positioning mechanism 50 drives the conveying material 70 to descend, and the lifting and blocking mechanism 60 on the right side also descends. Then, the second conveyor belt 22 and the third conveyor belt 23 can be used to convey the conveying material 70 to the right to achieve discharge.

[0064] Scenario 2 (Left in, left out)

[0065] like Figure 4 As shown, during feeding, both the first conveyor belt 21 and the second conveyor belt 22 convey materials from left to right, and the blocking surfaces of the two lifting blocking mechanisms 60 are arranged facing left. At this time, the conveyed material 70 will be placed on the first conveyor belt 21, and both lifting blocking mechanisms 60 are in the raised state. Therefore, when the first conveyor belt 21 conveys the conveyed material 70 to the right, once the conveyed material 70 comes into contact with the lifting blocking mechanism 60 on the left, it indicates that the conveyed material 70 has reached the barcode scanning station, and the barcode scanner 30 can then be used to scan the conveyed material 70.

[0066] After the scanning operation is completed, the lifting and blocking mechanism 60 on the left is lowered, and the first conveyor belt 21 and the second conveyor belt 22 are used to send the conveyed material 70 to the lifting and positioning mechanism 50 until the conveyed material 70 comes into contact with the lifting and blocking mechanism 60 on the right. This indicates that the conveyed material 70 has reached the laser processing station. At this time, the lifting and positioning mechanism 50 can be used to lift the conveyed material 70 upward for processing.

[0067] After the laser processing is completed, the lifting and positioning mechanism 50 drives the conveying material 70 to descend, and the lifting and blocking mechanism 60 on the left also descends. The first conveyor belt 21 and the second conveyor belt 22 are switched to convey from right to left. At this time, the first conveyor belt 21 and the second conveyor belt 22 can be used to convey the conveying material 70 to the left to achieve the discharge.

[0068] Scene 3 (Enter from right, exit from left)

[0069] like Figure 5 As shown, the first conveyor belt 21, the second conveyor belt 22, and the third conveyor belt 23 are all set to convey from right to left. The installation state of the barcode scanner 30 and the two lifting blocking mechanisms 60 is changed so that the barcode scanner 30 is installed on the third conveyor belt 23, and the blocking surfaces of the two lifting blocking mechanisms 60 are arranged to the right. At this time, the conveyed material 70 will be placed on the third conveyor belt 23, and the two lifting blocking mechanisms 60 are in the raised state. So when the third conveyor belt 23 conveys the conveyed material 70 to the left, once the conveyed material 70 comes into contact with the lifting blocking mechanism 60 on the right, it indicates that the conveyed material 70 has reached the barcode scanning station, and the barcode scanner 30 can be used to scan the conveyed material 70.

[0070] After the scanning operation is completed, the lifting and blocking mechanism 60 on the right side is lowered, and the third conveyor belt 23 and the second conveyor belt 22 are used to send the conveyed material 70 to the lifting and positioning mechanism 50 until the conveyed material 70 comes into contact with the lifting and blocking mechanism 60 on the left side. This indicates that the conveyed material 70 has reached the laser processing station. At this time, the lifting and positioning mechanism 50 can be used to lift the conveyed material 70 upward for processing.

[0071] After the laser processing is completed, the lifting and positioning mechanism 50 drives the conveying material 70 to descend, and the lifting and blocking mechanism 60 on the left also descends. Then, the first conveyor belt 21 and the second conveyor belt 22 can be used to convey the conveying material 70 to the left to achieve discharge.

[0072] Scene 4 (Enter from right, exit from right)

[0073] like Figure 6 As shown, during feeding, both the second conveyor belt 22 and the third conveyor belt 23 convey materials from right to left, and the blocking surfaces of the two lifting blocking mechanisms 60 are arranged to the right. At this time, the conveyed material 70 will be placed on the third conveyor belt 23, and both lifting blocking mechanisms 60 are in the raised state. Therefore, when the third conveyor belt 23 conveys the conveyed material 70 to the left, once the conveyed material 70 comes into contact with the lifting blocking mechanism 60 on the right, it indicates that the conveyed material 70 has reached the barcode scanning station, and the barcode scanner 30 can then be used to scan the conveyed material 70.

[0074] After the scanning operation is completed, the lifting and blocking mechanism 60 on the right side is lowered, and the second conveyor belt 22 and the third conveyor belt 23 are used to send the conveyed material 70 to the lifting and positioning mechanism 50 until the conveyed material 70 comes into contact with the lifting and blocking mechanism 60 on the left side. This indicates that the conveyed material 70 has reached the laser processing station. At this time, the lifting and positioning mechanism 50 can be used to lift the conveyed material 70 upward for processing.

[0075] After the laser processing is completed, the lifting and positioning mechanism 50 drives the conveying material 70 to descend, and the lifting and blocking mechanism 60 on the right side also descends. The second conveyor belt 22 and the third conveyor belt 23 are switched to convey from left to right. At this time, the second conveyor belt 22 and the third conveyor belt 23 can be used to convey the conveying material 70 to the right to achieve discharge.

[0076] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
