Description

Technical Field

[0001] This utility model relates to the field of board loading machine structure, specifically a high-precision board loading machine. Background Technology

[0002] The PCB loading machine is used to load PCB boards, facilitating further processing of the PCB boards. Currently, most workshops have achieved automated PCB loading.

[0003] Board loading machines typically employ telescopic drive cylinders to push PCBs out of the stacking frame. This process requires effective coordination between the lifting mechanism and the telescopic drive cylinders; ineffective coordination can damage the PCB surface, reducing yield. Using vision sensors is a mainstream solution to improve accuracy, but its high cost hinders cost control for businesses. Controlling the lifting distance via a controller cannot guarantee long-term effectiveness and requires frequent adjustments to maintain yield, making it impractical. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision board loading machine to solve the problem that existing board loading machines require frequent adjustment and alignment, which is not conducive to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision pallet loading machine, comprising: a frame; a first conveying unit disposed on one side of the frame for inputting a pallet stacking frame, wherein the pallet stacking frame is provided with a plurality of placement slots for placing pallets; a second conveying unit disposed above the first conveying unit for outputting the pallet stacking frame; a lifting unit disposed inside the frame for driving the pallet stacking frame to lift; a third conveying unit disposed on the other side of the frame for conveying the pallets on the pallet stacking frame; and a pushing unit for pushing out the pallets on the conveying pallet stacking frame, wherein the pushing unit includes an installation structure and a pushing structure, the pushing structure being floatingly disposed on the installation structure, the pushing structure including a pushing rod and a positioning block, the positioning block extending into the placement slots.

[0006] As a further improvement to the above technical solution:

[0007] The mounting structure includes an adjustment frame and a guide rail disposed on the second conveying section. The adjustment frame and the guide rail are slidably engaged. An installation plate is slidably disposed on the adjustment frame. The positioning block is fixedly installed on the installation plate. A positioning pusher is disposed on one side of the adjustment frame. The pusher rod is installed on the installation plate.

[0008] The positioning block includes an upper movable block and a lower movable block, which are hinged at one end and have elastic components at the other end. A sliding wheel can be installed on the contact surface between the movable block and the placement groove to ensure smooth operation.

[0009] The first conveying unit is located on the lower part of one side of the frame and includes a first conveyor belt and a first driver. The first driver drives the first conveyor belt to rotate.

[0010] The second conveying unit is located on the upper part of one side of the frame and includes a second conveyor belt and a second driver. The second driver drives the second conveyor belt to rotate.

[0011] The third conveying unit includes a third conveyor belt and a third driver, and the third driver drives the third conveyor belt to rotate.

[0012] The lifting unit includes a guide rod and a hopper that slides with the guide rod. A lifting screw is threadedly fitted onto the hopper via a screw sleeve. A fourth conveyor belt and a fourth driver are provided on the hopper. The fourth driver drives the fourth conveyor belt to rotate. A fifth driver is provided at the upper end of the lifting screw to drive the lifting screw to rotate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] High precision and low defect rate: Through an improved pusher unit design, the pusher structure can be floatingly mounted on the mounting structure, and the position of the pusher rod can be automatically adjusted according to the position of the placement slot. This design ensures the accuracy of the equipment when pushing the plate, significantly reducing the defect rate and improving product quality.

[0015] Reduced debugging costs: In existing technologies, the pushing unit typically uses a cylinder or hydraulic cylinder to push the plate out of the stacking frame, and the accuracy of the pushing is ensured by controlling the lifting height of the lead screw. However, the lifting height of the lead screw can be affected by mechanical wear, leading to errors and requiring frequent equipment adjustments to ensure normal operation. This embodiment improves the pushing structure, avoiding errors caused by mechanical wear, thereby effectively reducing debugging costs and improving the long-term stability and reliability of the equipment.

[0016] Easy to maintain and operate: Reduced mechanical wear and tear lowers maintenance requirements and simplifies operation. The positioning block design allows operators to easily perform positioning and pushing operations, reducing the possibility of human error.

[0017] In summary, the high-precision board loading machine of this embodiment achieves multiple beneficial effects, such as high precision, low defect rate, reduced debugging costs, improved equipment operating efficiency, easy maintenance and operation, and strong adaptability, through the improved design of the pushing unit, which significantly enhances the performance and practicality of the board loading machine.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1 to 5 As shown, the high-precision pallet loading machine of this embodiment includes: a frame 1; a first conveying unit 2, disposed on one side of the frame 1, for inputting a pallet frame 10, the pallet frame 10 being provided with a plurality of placement slots 100 for placing pallets 11; a second conveying unit 3, disposed above the first conveying unit 2, for outputting the pallet frame 10; a lifting unit 4, disposed inside the frame 1, for driving the pallet frame 10 to lift; and a third conveying unit 5, disposed on the other side of the frame 1, for conveying the pallets 11 on the pallet frame 10.

[0033] The first conveyor section 2 is located on the lower part of one side of the frame 1, and includes a first conveyor belt 21 and a first driver 22. The first driver 22 drives the first conveyor belt 21 to rotate.

[0034] The second conveyor unit 3 is located on the upper side of one side of the frame 1, and includes a second conveyor belt 31 and a second driver 32. The second driver 32 drives the second conveyor belt 31 to rotate. Both the first driver 22 and the second driver 32 include a motor or a corresponding tensioning mechanism to ensure the normal operation of the conveyor belt. A proximity sensor can be installed on the side of the conveyor belt, and the operation will stop when the stacking frame 10 reaches a preset position.

[0035] The third conveyor unit 5 includes a third conveyor belt 51 and a third driver 52, which drives the third conveyor belt 51 to rotate. The third conveyor belt 51 is a synchronous belt, and the third driver 52 is a stepper motor or a servo motor, which enables the synchronous belt to operate.

[0036] The lifting unit 4 includes a guide rod 41 and a hopper 42 that slides with the guide rod 41. A lifting screw 43 is threadedly fitted onto the hopper 42 via a screw sleeve. A fourth conveyor belt 44 and a fourth driver 45 are provided on the hopper 42. The fourth driver 45 drives the fourth conveyor belt 44 to rotate. A fifth driver 46 is provided at the upper end of the lifting screw 43 to drive the lifting screw 43 to rotate.

[0037] The pushing unit 6 is used to push the plate 11 out of the conveyor stack frame 10. The pushing unit 6 includes an installation structure and a pushing structure. The above structures are all existing product designs, such as... Figures 6 to 9 As shown, the difference between this embodiment and the prior art lies in the different pushing unit 6. In the prior art, the pushing unit 6 uses a cylinder or hydraulic cylinder to push the plate 11 out of the stacking frame 10. It uses a control screw to raise and lower the height to ensure the accuracy of the push. Since the raising and lowering height of the screw is subject to mechanical wear and error, the equipment needs to be frequently adjusted to ensure normal operation. This embodiment improves the pushing structure, which can effectively reduce the adjustment cost and ensure the long-term normal operation of the equipment.

[0038] The floating mechanism is mounted on the installation structure and includes a push rod 621 and a positioning block 622. The positioning block 622 extends into the placement groove 100. The floating mechanism allows for adjustment of the push rod 621's position. Positioning is achieved by inserting the positioning block 622, and the push rod 621's position is automatically adjusted according to the position of the placement groove 100, ensuring equipment accuracy and reducing the defect rate.

[0039] The mounting structure includes an adjusting frame 12 and a guide rail 13 mounted on the second conveying section 3. The adjusting frame 12 and the guide rail 13 are slidably fitted together. A mounting plate is slidably mounted on the adjusting frame 12, and a positioning block 622 is fixedly mounted on the mounting plate. A positioning pusher 14 is provided on one side of the adjusting frame 12, and a pusher rod 621 is mounted on the mounting plate. The floating here is mainly sliding in the Z direction. The X direction is the equipment running direction. The Y direction is not discussed here. The adjustment in the Y direction is achieved by modifying the size of the pushing unit 6 according to the size of the stacking frame 10.

[0040] The positioning block 622 includes an upper movable block 623 and a lower movable block 624. One end of the upper movable block 623 and the lower movable block 624 is hinged (this hinge is either a rigid connection where the upper and lower movable blocks can rotate via a pin, or a flexible connection where they are directly connected, ensuring that one end of the upper movable block 623 and the lower movable block 624 can move; if it is a hinge, both ends can be provided with elastic structures to ensure reset). The other end of the upper movable block 623 and the lower movable block 624 is provided with an elastic component 625. The elastic component 625 is a spring, which is compressed upon entry, allowing the movable block to enter and be positioned. After leaving the placement groove 100, it elastically returns to its original position. The design here is such that one end of the upper movable block 623 and the lower movable block 624 is closed, and the other end has an open structure, with the open structure larger than the size of the placement groove 100 (the head size is smaller than the size of the placement groove 100), to ensure that the upper and lower movable blocks can be inserted into the placement groove 100 and can be easily withdrawn. Another advantage of this design is that it facilitates alignment, allowing the heads of the upper and lower movable blocks to be quickly inserted into the placement slot 100.

[0041] In use, the pallet frame 10 is placed on the first conveyor section 2, and the first driver 22 drives the first conveyor belt 21 to rotate, so that the pallet frame 10 enters the 42. The fourth driver 45 drives the fourth conveyor belt 44 to rotate, so that the pallet frame 10 reaches the set position.

[0042] The fifth drive 46 is started to drive the lifting screw 43 to rotate (the controller controls it to run a certain distance and stop), so that the stacking frame 10 moves upward. Then, the positioning pusher 14 pushes the positioning block 622 into the placement slot 100. Due to the sliding cooperation between the mounting plate and the adjusting frame 12, the push rod 621 moves accordingly. Then, the push rod 621 is started to push the plate 11 out of the placement slot 100, so that the plate 11 enters the third conveyor belt 51. The third drive 52 drives the third conveyor belt 51 to rotate, completing the unloading of the plate 11.

[0043] Repeat the above actions to complete the unloading of all the plates 11 inside the stacking frame 10. Then, the fourth driver 45 drives the fourth conveyor belt 44 to rotate, so that the stacking frame 10 enters the second conveyor belt 31. The second driver 32 drives the second conveyor belt 31 to rotate, and the stacking frame 10 is unloaded.

[0044] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model 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 utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
