Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production equipment, in particular to a loading and unloading lift truck for a circuit board press. Background Art

[0002] During the production process of circuit boards, it is not completed by only one device, but different pressing processes are completed by multiple devices. Therefore, semi-finished products will be transferred between various devices to complete the loading and unloading operations of the corresponding devices.

[0003] At present, the semi-finished products of existing circuit boards are basically in the form of a board structure, so they are usually defined as material boards. When transferring between the material boards and various devices, it is generally through manual grasping for unloading, and then manually pushing into the feed bin for loading. Although this method can achieve the loading and unloading operations of the material boards, it consumes too much manpower and is not conducive to the realization of automated production line processing.

[0004] Therefore, it is necessary to make improvements in view of the deficiencies of the prior art. Content of the Utility Model

[0005] Aiming at the deficiencies existing in the above-mentioned prior art, the purpose of the utility model is to provide a loading and unloading lift truck for a circuit board press that can complete automatic loading and unloading.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A loading and unloading lift truck for a circuit board press includes a track, a chassis, a lifting mechanism, a workbench, jacks arranged on the board material, and a main machine arranged on the chassis for controlling the overall work to proceed in an orderly manner. The chassis is provided with wheels that are in contact with the track and can roll back and forth along the extension direction of the track. The lifting mechanism is established between the chassis and the workbench, enabling the workbench to be lifted relative to the chassis. A placing surface for placing the board material is arranged on the workbench. A slide rail is arranged in the middle of the placing surface, and a sliding seat is installed on the slide rail. A rotatable screw rod and a first motor for driving the screw rod to rotate are arranged at the same position of the workbench on the slide rail. The sliding seat is connected to the screw rod through a nut seat. A pushing plate is hinged on the sliding seat, and a plugging column corresponding to the jack is arranged on the pushing plate. At least one cylinder is arranged on the sliding seat, and the pushing head of the cylinder abuts against the lower end surface of the pushing plate;

[0008] Wherein, when the pushing head of the cylinder does not perform pushing, the height of the plugging column is lower than the height of the placing surface.

[0009] Preferably, roller shaft groups are arranged on both sides of the workbench, and the roller shaft surfaces in the roller shaft groups are flush with each other to form the placing surface.

[0010] Preferably, each roller in the roller group is provided with a synchronous pulley, and at least two second motors are arranged on the workbench. The second motors are respectively connected to the corresponding synchronous pulleys through synchronous belts, so that the rollers in the roller group rotate in the same direction.

[0011] Preferably, the workbench is evenly provided with limit rollers on the outer side of the roller group.

[0012] Preferably, a guiding edge is provided at the top end of the insertion post.

[0013] Preferably, the lifting mechanism is a hydraulic lift.

[0014] Preferably, at least one of the wheels is a driving wheel.

[0015] Due to the adoption of the above scheme, the utility model moves to the corresponding equipment through the track, combines the lifting of the workbench by the lifting mechanism, makes the tabletop of the workbench flush with the feeding port of the equipment, and finally relies on the pushing plate to push the material plate to complete the loading, or relies on the docking of the insertion post on the pushing plate and the jack on the material plate to complete the unloading, so that the automatic loading and unloading between various equipment can be completed as a whole.

[0024] Such as Figures 1 to 5As shown in the figure, a loading and unloading lift truck for a circuit board press provided in this embodiment includes a track 1, a chassis 2, a lifting mechanism 3, a workbench 4, a jack 5 provided on a sheet material 100, and a main machine 6 provided on the chassis 2 for controlling the orderly progress of the overall work. The chassis 2 is provided with wheels 7, and at least one of the wheels 7 is a driving wheel. For example, a hub motor is built into the wheel 7. The wheel 7 abuts against the track 1 and can roll back and forth along the extension direction of the track 1. The lifting mechanism 3 is a hydraulic lift. The lifting mechanism 3 is established between the chassis 2 and the workbench 4 so that the workbench 4 can be lifted relative to the chassis 2. A placing tabletop for placing the sheet material 100 is provided on the workbench 4. A slide rail 8 is provided in the middle of the placing tabletop. A sliding seat 9 is installed on the slide rail 8. At the same position of the workbench 4 where the slide rail 8 is located, a rotatable screw 10 and a first motor 11 for driving the screw 10 to rotate are provided. The sliding seat 9 is connected to the screw 10 through a nut seat 12. A push plate 13 is hinged on the sliding seat 9. A plug column 14 corresponding to the jack 5 is provided on the push plate 13. At least one cylinder 15 is provided on the sliding seat 9. The push head of the cylinder 15 abuts against the lower end surface of the push plate 13;

[0025] Among them, when the push head of the cylinder 15 does not push, the height of the plug column 14 is lower than the height of the placing tabletop.

[0026] When this embodiment works specifically, first place the sheet material 100 on the placing tabletop. The push head of the cylinder 15 is lifted so that the side of the plug column 14 abuts against the side of the sheet material 100. Then the wheels 7 operate to move the whole along the track 1 to the first device. The lifting mechanism 3 starts to work and raises the workbench 4 to the feeding port of the device to align the sheet material 100 with the feeding port. The first motor 11 works to rotate the screw 10 so that the sliding seat 9 moves along the direction of the slide rail 8, thereby gradually pushing the sheet material 100 outwards until the sheet material 100 is sent into the material port of the device to complete the loading. When taking the material, the device will first open the material port to expose the end of the sheet material 100 provided with the jack 5. The workbench 4 rises to the corresponding height. The cylinder 15 resets and does not lift the push plate 13. Then the first motor 11 drives to push the push plate 13 to the sheet material 100 and make the plug column 14 located at the jack 5 of the sheet material 100. Subsequently, the cylinder 15 pushes upwards to make the push plate 13 rotate along the hinge point so that the plug column 14 is inserted into the jack 5 (it should be noted that the aperture of the jack 5 is larger than the diameter of the plug column 14 to facilitate better insertion into the jack 5). After the insertion is completed, the first motor 11 rotates back and the sliding seat 9 retracts. The sheet material 100 is gradually pulled out of the device and gradually placed on the placing tabletop until the sheet material 100 is completely pulled out. Finally, the lifting mechanism 3 resets and the whole moves to another device for loading, and so on until the processing of the sheet material 100 is completed.

[0027] Further, to make the pushing and pulling of the sheet material 100 smoother and reduce the friction between the placing tabletop and the sheet material, roller shaft groups 16 are provided on both sides of the workbench 4 in this embodiment. The roller shaft surfaces in the roller shaft groups 16 are flush with each other to form the placing tabletop, so that the end faces of the roller shafts are used as the bearing, which can effectively reduce the frictional resistance.

[0028] Further, since the material of the circuit board sheet itself has a certain weight, a single first motor 11 cannot better complete the pushing and pulling work. Therefore, each roller shaft in the roller shaft group 16 in this embodiment is provided with a synchronous pulley 17, and at least two second motors 18 are provided on the workbench 4. The second motors 18 are respectively connected to the corresponding synchronous pulleys 18 through synchronous belts 19, so that the roller shafts in the roller shaft group 16 rotate in the same direction, and thus the second motors 18 are relied on to provide auxiliary power.

[0029] Further, to prevent the sheet material 100 from running off track, limit rollers 20 are evenly provided on the outer side of the workbench 4 where the roller shaft group 16 is located in this embodiment. In this way, when the sheet material 100 moves, centering and limiting can be carried out by relying on the limit rollers 20, and the sheet material 100 will not run off track, especially when the insertion post 14 is pushed without being inserted into the insertion hole 5.

[0030] Further, to make the insertion post 14 better inserted into the insertion hole 5, a guiding edge is provided at the top end of the insertion post 14 in this embodiment. Relying on this guiding edge, the positioning and guiding functions can be achieved. Of course, the insertion hole 5 can also be formed in a conical shape at the hole opening.

[0031] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
