Description

Technical Field

[0001] This invention relates to the field of pot cover plate production equipment, specifically to a fully automatic screw-driving device for pot cover plates with multiple holes. Background Technology

[0002] Currently, the existing production process for pot cover plates generally involves drilling multiple screw holes in the pot cover plate and then using an automatic screw-driving device to drive the screws into the pot cover plate. Because an automatic screw-driving device is used, it is necessary to manually check the position of the screw holes or position the pot cover plate before the screws are driven into the pot cover plate to prevent the automatic screw-driving device from deviating from the screw holes and damaging the pot cover plate. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a fully automatic screw-driving device for multi-hole pot cover plates. This solves the problem that existing fully automatic screw-driving devices require manual inspection of the screw hole positions or positioning of the pot cover plate to prevent the automatic screw-driving device from deviating from the screw holes and damaging the pot cover plate.

[0004] The technical solution adopted in this invention is as follows:

[0005] A fully automatic screw-driving device for a multi-hole pot cover includes: a base frame, a side frame mounted at one end of the base frame, a screw-driving assembly mounted on the upper part of the side frame, multiple sets of guide rails perpendicular to the side frame mounted on the base frame, and multiple pot cover positioning assemblies movable along the guide rails mounted on the guide rails. Each pot cover positioning assembly includes a pair of positioning posts, a top post at the top of each positioning post, and a supporting arc-shaped component mounted on the top post. The supporting arc-shaped components of the pair of positioning posts are arranged opposite to each other. The supporting arc-shaped component has a first mounting groove and a second mounting groove inside. A piston plate is provided in the second mounting groove, and a piston block is provided in the first mounting groove. The top of the piston block extends beyond the upper surface of the supporting arc-shaped component. The first mounting groove is connected to the second mounting groove through a liquid guide hole. Two mounting slots are provided. The first mounting slot and the second mounting slot space inside the piston plate near the first mounting slot are filled with hydraulic oil. A third mounting slot is connected to the outside of the second mounting slot. A piston rod is mounted on the outside of the piston plate. The end of the piston rod extends into the third mounting slot. A piston rod is mounted at the end of the piston rod. A gear that meshes with the rack is provided on one side. A rotating shaft is provided at the center of the gear. A rotating rod is connected to the bottom of the rotating shaft. A fixed seat is mounted at the bottom of the rotating rod. A side cylinder is mounted on one side of the fixed seat. A movable crossbar is provided inside the side cylinder. A directional light source emitter is mounted on the movable crossbar. A top plate is mounted on the top of the side frame. A photosensitive sensor is mounted on the lower surface of the top plate. The photosensitive sensor is externally connected to a control unit.

[0006] This invention involves placing the pot cover plate on the supporting arc-shaped component of the pot cover plate positioning assembly, which compresses the piston block, further pushing the piston plate, piston rod, and rack to move, driving the gears and rotating shaft to rotate. As the shaft rotates, the movable crossbar deflects, aligning the directional light source emitter with the screw holes on the pot cover plate. The light emitted from the directional light source passes through the screw holes and illuminates the top plate, where it is received by a photosensitive sensor positioned at a preset location. The received light signal is transmitted to the control unit. When all photosensitive sensors accurately transmit signals to the control unit, the control unit determines that the pot cover plate is installed correctly and the screw hole positions are also accurate. This invention solves the problem of existing fully automatic screw-driving devices requiring manual detection of the screw hole positions or positioning of the pot cover plate to prevent the automatic screw-driving device from deviating from the screw holes and damaging the pot cover plate.

[0007] Optionally, the screw-driving assembly includes an automatic screw-driving module and a lift for driving the automatic screw-driving module to move up and down.

[0008] Optionally, the supporting arc-shaped component is provided with an annular groove, and the rotating rod is provided with a limiting block, which is installed in the annular groove.

[0009] Optionally, a spring is provided between the piston plate and the end wall of the second mounting groove.

[0010] Optionally, the portion of the rotating rod located inside the supporting arc-shaped component is provided with a first contact arc plate, and the supporting arc-shaped component is also provided with a second contact arc plate that is adapted to the first contact arc plate.

[0011] Optionally, the first contact arc plate is provided with a pair of first conductive contacts, and the second contact arc plate is provided with a pair of second conductive contacts. When the rotating rod rotates, the pair of first conductive contacts and the pair of second conductive contacts come into contact with each other, and the pair of second conductive contacts are connected to the two poles of an external power supply.

[0012] Optionally, the movable crossbar is provided with a pair of third conductive contacts.

[0013] Optionally, a pair of parallel conductive plates are mounted on the side cylinder, and the third conductive contact head continuously contacts the conductive plates when it moves.

[0014] Optionally, a pair of third conductive contacts are electrically connected to two pins of the directional light source emitter via wires.

[0015] Optionally, a pair of conductive plates are connected to a pair of first conductive contacts via separate wires. This invention, through the rotation of the rotating rod, causes the pair of first conductive contacts to contact a pair of second conductive contacts. The pair of second conductive contacts are connected to the two poles of an external power supply, further cooperating with the pair of third conductive contacts on the movable crossbar to continuously contact the pair of conductive plates as they move. The pair of third conductive contacts are electrically connected to the two terminals of the directional light source emitter via wires. The pair of conductive plates are connected to the pair of first conductive contacts via separate wires, ensuring that the directional light source emitter is only powered on and emits light after the rotating rod has rotated to a predetermined position, reducing energy loss and preventing the directional light source from accidentally shining into the eyes at the initial position before the pot lid is placed.

[0016] Beneficial effects

[0017] 1. This invention involves placing the pot cover plate on the supporting arc-shaped component of the pot cover plate positioning assembly, squeezing the piston block, and further pushing the piston plate, piston rod, and rack to move, driving the gears and rotating shaft to rotate. As the rotating shaft rotates, the movable crossbar deflects, causing the directional light source emitter to align with the screw holes on the pot cover plate. The light emitted by the directional light source passes through the screw holes and illuminates the top plate, where it is received by a photosensitive sensor at a preset position. The received light signal is transmitted to the control unit. When all photosensitive sensors accurately transmit signals to the control unit, the control unit determines that the pot cover plate is installed accurately and the screw hole positions are also accurate. This invention solves the problem of existing fully automatic screw-driving devices requiring manual detection of the screw hole positions or positioning of the pot cover plate to prevent the automatic screw-driving device from deviating from the screw holes and damaging the pot cover plate. 2. This invention uses a rotating rod to bring a pair of first conductive contacts into contact with a pair of second conductive contacts. The pair of second conductive contacts are connected to the two poles of an external power supply. Furthermore, as the pair of third conductive contacts on the movable crossbar move, they continuously contact a pair of conductive plates. The pair of third conductive contacts are electrically connected to the two terminals of the directional light source emitter via wires. The pair of conductive plates are connected to a pair of first conductive contacts via wires. This ensures that the directional light source emitter is powered on and emits light only after the rotating rod has rotated to a predetermined position, reducing energy loss and preventing the directional light source from accidentally shining into people's eyes at the initial position where the pot lid is not placed.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0031] Example 1

[0032] The technical solution adopted in this invention is as follows:

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, this invention discloses a fully automatic screw-driving device for a multi-hole pot lid, comprising: a base frame 1, a side frame 2 mounted at one end of the base frame, a screw-driving assembly 3 mounted on the upper part of the side frame, multiple sets of guide rails 4 perpendicular to the side frame mounted on the base frame, multiple pot lid positioning assemblies 5 movable along the guide rails mounted on the guide rails, each pot lid positioning assembly including a pair of positioning posts 6, a top post 7 at the top of each positioning post, and a supporting arc-shaped component 8 mounted on the top post, the supporting arc-shaped components of the pair of positioning posts being arranged opposite to each other; the supporting arc-shaped component has a first mounting groove 9 and a second mounting groove 10 inside, a piston plate 12 in the second mounting groove, and a piston block 11 in the first mounting groove. The top of the piston block extends beyond the upper surface of the supporting arc-shaped component. The first mounting groove is connected to the second mounting groove through the fluid guide hole 39. The space between the first mounting groove and the second mounting groove on the inner side of the piston plate near the first mounting groove is filled with hydraulic oil. The outer side of the second mounting groove is connected to the third mounting groove 13. The piston rod 14 is mounted on the outer side of the piston plate. The end of the piston rod extends into the third mounting groove. The end of the piston rod is mounted with a rack 16. A gear 17 that meshes with the rack is provided on one side of the rack. A rotating shaft 18 is provided at the center of the gear. A rotating rod 19 is connected to the bottom of the rotating shaft. A fixed seat 20 is mounted at the bottom of the rotating rod. A side cylinder 21 is mounted on one side of the fixed seat. A movable crossbar 22 is provided inside the side cylinder.

[0034] In this embodiment, the movable crossbar can move along the side passage, allowing the operator to move it. A directional light source emitter 23 is mounted on the movable crossbar, and a top plate 33 is mounted on the top of the side frame. A photosensitive sensor is mounted on the lower surface of the top plate. The photosensitive sensor is externally connected to a control unit 41. In this embodiment, the control unit is electrically connected to an alarm 42 or a display.

[0035] The screw-driving assembly includes an automatic screw-driving module 15 and a lifting mechanism 24 for driving the automatic screw-driving module to move up and down. The supporting arc-shaped member has an annular groove 38, and the rotating rod has a limiting block 25 installed in the annular groove. A spring 26 is provided between the piston plate and the end wall of the second mounting groove. It should be noted that in this embodiment, the spring is used to provide the tension that causes the piston plate to spring back.

[0036] The portion of the rotating rod located inside the supporting arc-shaped component is provided with a first contact arc plate 27, and the supporting arc-shaped component is also provided with a second contact arc plate 28 that is adapted to the first contact arc plate.

[0037] The first contact arc plate is provided with a pair of first conductive contacts 29. The second contact arc plate is provided with a pair of second conductive contacts 30. When the rotating rod rotates, the pair of first conductive contacts and the pair of second conductive contacts come into contact with each other, and the pair of second conductive contacts are connected to the two poles of an external power supply. The movable crossbar is provided with a pair of third conductive contacts 31.

[0038] The side cylinder is equipped with a pair of parallel conductive plates 32, and the third conductive contact head continuously contacts the conductive plates as it moves. The pair of third conductive contacts are electrically connected to the two terminals of the directional light source emitter via wires. The pair of conductive plates are connected to a pair of first conductive contacts via wires. A groove 36 is provided on the outer side of the piston block, and a limiting member 37 is provided inside the supporting arc-shaped member, which is inserted into the groove. In this embodiment, the power supply is sequentially connected to the second conductive contact head, the first conductive contact head, the conductive plates, and the third conductive contact head, forming a closed circuit, thus energizing the directional light source emitter.

[0039] The control unit of this invention can be a computer system or a PLC (programmable logic controller).

[0040] In this embodiment, the pot cover is placed on the supporting arc-shaped component of the pot cover positioning assembly, squeezing the piston block and further pushing the piston plate, piston rod, and rack to move, driving the gears and rotating shaft to rotate. As the rotating shaft rotates, the movable crossbar deflects, aligning the directional light source emitter with the screw holes on the pot cover. The light emitted by the directional light source passes through the screw holes and illuminates the top plate, where it is received by a photosensitive sensor at a preset position. The received light signal is transmitted to the control unit. When all photosensitive sensors accurately transmit signals to the control unit, the control unit determines that the pot cover is installed correctly and the screw hole positions are also accurate. If the control unit determines that the pot cover is installed incorrectly or the screw hole positions are incorrect, the control unit activates an alarm to alert the operator.

[0041] Simultaneously, the rotating rod rotates, causing a pair of first conductive contacts to come into contact with a pair of second conductive contacts. The two poles of the external power supply are connected to the pair of second conductive contacts, which in turn continuously contact a pair of conductive plates as the pair of third conductive contacts on the movable crossbar move. The pair of third conductive contacts are electrically connected to the two terminals of the directional light source emitter through wires. The pair of conductive plates are connected to a pair of first conductive contacts through wires, so that the directional light source emitter will only be powered on and emit light after the rotating rod rotates to the predetermined position, reducing energy loss and preventing the directional light source from accidentally shining into people's eyes at the initial position where the pot lid is not placed.

[0042] Example 2

[0043] like Figure 9 As shown, the difference between Embodiment 2 and Embodiment 1 is that the top column is provided with a detachable and rotatable rotating component 34, and an elastic pressing piece 35 is provided on one side of the rotating component.

[0044] In this embodiment, the rotating component is rotated so that the elastic pressing piece presses against the pot cover plate to prevent the pot cover plate from shifting.

[0045] The above description is merely a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformations made based on the description and drawings of the present invention, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present invention.
