Detailed Implementation

[0035] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0036] Example 1

[0037] like Figures 1 to 4 As shown in the figure, the plate feeder provided in this embodiment of the present invention includes the following parts:

[0038] The feeding conveyor 1 is used to send the turnover box filled with PCBs to the elevator 3 to feed the elevator 3.

[0039] The unloading conveyor 2 recycles the empty turnover boxes containing PCBs that have been delivered from the elevator 3;

[0040] Elevator 3 is used to raise the turnover box containing PCBs to cooperate with the ejection mechanism to push out the PCBs one by one and supply them to subsequent equipment. When the PCBs in the turnover box are pushed out, the empty turnover box is automatically sent to the unloading conveyor 2. Then the elevator 3 is lowered to the lowest limit position, and the next fully loaded turnover box enters and the above cycle is repeated.

[0041] To accommodate various PCB turnover boxes, this embodiment includes an adjustment mechanism for driving the ejection mechanism to move along the width direction of the feeding conveyor 1. Specifically, the adjustment mechanism includes a base 4, a guide rod 5, and a drive mechanism 6. The base 4 supports the ejection mechanism, the guide rod 5 is mounted on the conveyor frame 7, and a guide sleeve 8 that cooperates with the guide rod 5 is mounted on the base 4. The drive mechanism 6 uses a ball screw motor assembly, and the nut of the ball screw motor assembly is connected to the base 4, which can drive the base 4 to move along the length direction of the guide rod 5. The guide rod 5 is perpendicular to the conveying direction of the feeding conveyor 1, that is, it is equivalent to the width direction of the feeding conveyor 1.

[0042] The ball screw motor assembly is existing technology, so its principle and installation method will not be described in detail here;

[0043] The ejection mechanism of this embodiment includes a guide rail 9, a slider 10, a push rod 11, and a second drive mechanism 12. The guide rail 9 is fixed on the base 4, the slider 10 is slidably mounted on the guide rail 9, and the push rod 11 is fixedly connected to the slider 10. In addition, some guide blocks and other structures can be installed on the conveyor frame 7 to prevent the push rod 11 from deviating. The second drive mechanism 12 can drive the slider 10 to move along the guide rail 9, thereby completing the work of ejecting PCBs one by one.

[0044] The drive mechanism 2 12 can be a cylinder or a hydraulic cylinder. In this embodiment, a belt conveyor mechanism is selected, and the belt of the belt conveyor mechanism is connected to the slider 10.

[0045] After replacing the PCB with a different specification, the position of the ejection mechanism is changed by adjusting the mechanism's adaptability to ensure the stability of PCB pushing;

[0046] In addition, sensors are installed at both the input and output ends of the unloading conveyor and the loading conveyor to detect the position of the turnover box, which facilitates subsequent automation design.

[0047] The bottom of the elevator 3, the feeding conveyor 2 and the unloading conveyor 1 are all equipped with level feet. To ensure the normal operation of the equipment, the level feet must be adjusted during installation to keep the equipment level.

[0048] Example 2

[0049] Based on Example 1, such as Figures 5 to 6 As shown, this embodiment proposes a plate feeding machine, whose lifting mechanism 3 includes a lifting plate 13, a conveying unit and a lifting unit 14. The conveying unit is installed on the lifting plate 13. The lifting unit 14 can be driven by a cylinder or a hydraulic cylinder. In this embodiment, a ball screw motor assembly is used. If appropriate, a corresponding guide assembly should also be provided to ensure that the lifting plate 13 can be lifted and lowered stably. The guide assembly is an existing structure, so it will not be described in detail here.

[0050] The conveying unit includes a drive assembly and multiple belt conveyor assemblies. The belt conveyor assembly includes a conveyor belt 15 and two pulleys 16. The drive assembly includes two drive shafts 17 and a drive mechanism 18 that drives the drive shafts 17 to rotate. The pulleys 16 are mounted on the drive shafts 17, and the drive shafts 17 are rotatably mounted on the lifting plate 13. The drive mechanism 18 can be a motor, and the output end of the motor is connected to the two drive shafts 17 through a chain drive mechanism.

[0051] The unloading conveyor 2 and the loading conveyor 1 also adopt the above-mentioned conveying unit form, but the difference is that the unloading conveyor 2 and the loading conveyor 1 can be equipped with multiple conveying units;

[0052] Example 3

[0053] Based on Example 2, such as Figures 6 to 7 As shown, this embodiment proposes a plate feeder. The conveying unit of the plate feeder includes at least three belt conveyor assemblies, and also includes at least one lifting baffle 19 assembly, which is located between two adjacent belt conveyor assemblies.

[0054] The lifting baffle 19 assembly includes a drive mechanism 20 and a baffle 19 installed at the output end of the drive mechanism 20. The baffle 19 is located between two adjacent belt conveyor assemblies. The drive mechanism 20 can be a pneumatic cylinder or a hydraulic cylinder. The drive mechanism 20 is also fixedly installed on the conveyor frame 7 / lifting plate 13.

[0055] After switching to a smaller PCB, raising the baffle 19 ensures that the turnover box is stably conveyed only on the belt conveyor assembly with a relatively small gap, preventing its position from shifting. When it is necessary to switch to a larger PCB, the baffle 19 can be lowered by the drive mechanism 20.

[0056] In addition, protective plates 21 are installed on both the conveyor frame 7 and the lifting plate 13. The protective plates 21 pass through the middle of the conveyor belt 15 to prevent the turnover box PCB from falling off the conveyor.

[0057] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit and essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0058] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
