Description

Technical Field

[0001] The utility model relates to the technical field of plate marking equipment, in particular to an assembly line marking and feeding mechanism. Background Art

[0002] When processing large quantities of PVC shock-proof board marking work, the applicant used an automatic loading assembly line laser marking machine. When the boards completed the cutting process and were transferred to the marking process, in order to avoid the boards being scattered, they would be placed in cartons for transportation. During the marking work, it was necessary to manually take the boards out of the cartons one by one and place them on the workbench of the marking machine for marking. However, this method is only suitable for small-batch operations. For large-scale production, the marking efficiency is poor.

[0003] The application document with application number CN201920736404.5 in the patent library discloses an automatic loading and unloading device for a laser marking machine. The loading and unloading device uses a Z-axis linear slide to control the lifting of the suction cup to absorb the plates in the carton, and then uses the X-axis linear slide to move the plates to the material channel provided with a marking machine workbench. The automated mechanical structure replaces manual loading, thereby improving work efficiency. However, after the Z-axis linear slide of this device absorbs the first plate, when it absorbs the remaining plates downwards, the rising and falling stroke of each plate absorbed is greater than the stroke of the previous plate absorption, which ultimately leads to its loading efficiency still being low. Utility Model Content

[0004] In order to solve the technical problem in the above-mentioned background technology that the Z-axis linear slide rail of the existing loading and unloading device, after sucking the first plate, sucks the remaining plates downward, and each time it sucks a plate, its rising and falling stroke is greater than the stroke of the previous plate sucking, which ultimately leads to its loading efficiency is still low, the utility model provides a production line marking and loading mechanism.

[0005] The technical solution of this utility model is as follows:

[0006] A marking and loading mechanism for an assembly line includes a support frame and a material box inside thereof. A supporting member is provided inside the material box for vertical sliding. The support frame is also provided with a lifting device that is transmission-connected to the supporting member and can drive the supporting member to move vertically. The upper end and at least one side of the material box are provided with openings, wherein the opening at the upper end of the material box is a material outlet, and the opening on the side is a material inlet. The present loading mechanism (a kind of assembly line marking loading mechanism) is applied to the front side of the feeding end of the conveyor channel of the marking machine, wherein the feeding end of the conveyor channel of the marking machine is also provided with a loading and unloading device (such as an automatic loading and unloading device of a laser marking machine with application number CN201920736404.5). When in use, the plate is first placed on the supporting member through the feeding port, and then the supporting member is driven by the lifting device to slide vertically upward along the inside of the material box. The loading and unloading device transports the plate from the discharge port position of the material box to the conveyor channel of the marking machine. When the loading and unloading device sucks the plate again, the lifting device can cooperate with the loading and unloading device to drive the supporting member to move upward, so that the rising and falling action strokes required for the Z-axis linear slide rail of the loading and unloading device to suck the plate each time are the same or the difference is controlled within a small range, thereby improving the working efficiency of plate loading.

[0007] As the core technical concept of the present invention, the lifting device includes a screw rod vertically arranged on the outside of the material box, and a driving module that can drive the screw rod to rotate. A strip is vertically provided on one side of the material box corresponding to the screw rod, and the supporting member passes through the strip and is threadedly connected to the screw rod to ensure that the plates can be placed neatly in the material box without being scattered. The lifting device is arranged on the outside of the material box to save space inside the material box, facilitate the placement of the plates, and improve the working stability of the feeding mechanism, thereby reducing downtime for debugging and improving work efficiency.

[0008] As a further implementation, two screw rods are provided on opposite sides of the material box, and the driving module is configured to drive the two screw rods to rotate synchronously.

[0009] Furthermore, the supporting member includes a support rod with both ends passing horizontally through the strip openings on both sides of the material box and vertically slidingly connected to the support frame. The spiral rod is connected to the support rod by a spiral transmission. The spiral transmission is a very stable transmission method. It can avoid the shaking or displacement of the plate caused by unstable transmission, and ensure that the supporting member always remains stable during the lifting process.

[0010] In order to improve the stability of the vertical movement of the supporting part, reduce jamming and improve work efficiency, several support rods are provided, and multiple support rods are provided corresponding to the strip openings on the same side of the material box. A connecting rod is provided between the ends of the several support rods, and the spiral rod is connected to the middle part of the connecting rod by a spiral transmission, and the spiral transmission connection makes the lifting process of the supporting part more precise and controllable.

[0011] Furthermore, a feeding plate is horizontally provided on the upper side of the support rod located in the inner part of the material box, which helps to more evenly distribute the weight of the plate, reduce the local pressure on the supporting member, and thus reduce the wear and failure rate of the supporting member.

[0012] As described above, the assembly line marking and loading mechanism has a driving module including a power source and a first transmission wheel connected thereto, and two second transmission wheels provided on two screw rods. A conveyor chain / conveyor belt is provided between the first transmission wheel and the two second transmission wheels to enable the two screw rods to rotate effectively and synchronously.

[0013] In order to ensure that the power source can transmit power to the two screw rods more fully and evenly, a tensioning device is also provided on the outside of the conveyor chain / conveyor belt.

[0014] In order to prevent dust and other impurities from entering the material box, a protective plate is provided on the outside of the support frame to protect components such as the lifting device from contamination. A discharge switch door is provided on the protective plate corresponding to the opening on the side of the material box to facilitate discharge. A maintenance switch door is provided on the protective plate corresponding to the two screw rods to facilitate maintenance and inspection.

[0015] The beneficial effect of the present invention is that by placing the plate in the material box and combining the lifting device with the loading and unloading device to lift the plate, this structure ensures the regular placement of the plate in the material box, and also makes the Z-axis linear slide rail of the loading and unloading device The lifting action stroke difference required for each time to absorb the plate is the same or can be controlled within a smaller range, thereby improving the work efficiency and stability of plate loading.
