Description

Technical Field

[0001] This utility model relates to a head-baking machine, specifically to a head-baking machine filament top wire bending device. Background Technology

[0002] Currently, there are two known types of filament bending devices for lamp head heating machines: one is mechanically controlled, and the other is pneumatically controlled. Both are front-to-back oblique push types, meaning they control the push head to tilt back and forth to bend the filament top wire that has been cut by scissors. Due to insufficient precision in the lamp head heating machine, if the top wire is too long after cutting, the rivet wire may be exposed; if it is too short, the top wire may not be pushed and may even be driven into the copper head by the rivet, causing the lamp to not light up, or the current to be too high. In particular, the outer diameter of the rivet hole on the copper head of an E12 filament lamp is only 5mm, which cannot completely eliminate the above-mentioned faults. Summary of the Invention

[0003] In order to overcome the shortcomings of existing filament and set wire bending, the purpose of this utility model is to provide a set wire bending device. This bending device can not only effectively solve the problem of exposed rivet wire due to long set wire, but also avoid the phenomenon of being driven into the copper head, thereby reducing the number of defective products.

[0004] The technical solution of this utility model is: a filament bending device for a heating head machine, comprising a bracket mounted on a heating head base and a filament winding mechanism. The bracket is mounted on the heating head base, and the filament winding mechanism is mounted on the bracket. The bracket includes: a base, a vertical shaft, a three-way connector, a limit switch shaft, a horizontal-to-vertical conversion seat, and a cylinder base plate shaft. The base is mounted on the heating head base, and the vertical shaft is mounted on the base. The middle of the vertical shaft is horizontally mounted with the limit switch shaft via the three-way connector, and the upper part of the vertical shaft is horizontally mounted with the cylinder base plate shaft via the horizontal-to-vertical conversion seat. The filament winding mechanism includes: a cylinder base plate frame, a cylinder, a fixed base plate, gears, a winding motor, an upper support for the winding tube, a fixed needle seat, a central fixed needle, a winding tube, a lower support for the winding tube, a tension spring, an upper bearing, a lower bearing, and a motor bracket. The cylinder base plate frame is mounted on the cylinder base plate shaft. The cylinder is suspended downwards on the bottom of the cylinder base plate. A fixed base plate is installed on the cylinder rod. The bottom surface of the fixed base plate is connected to one end of a tension spring via a first tension spring hook. The other end of the tension spring is connected to a second tension spring hook located on the baking head base. The top surface of the fixed base plate is equipped with a wire winding motor via a motor bracket. An upper support for the wire winding tube is installed on the housing of the wire winding motor. A lower support for the wire winding tube is installed on the fixed base plate. The wire winding tube is mounted on the upper and lower support supports via upper and lower bearings. A gear is fixed to the wire winding tube by a positioning screw. The gear meshes with the shaft gear of the wire winding motor. A fixed pin seat is installed on the housing of the wire winding motor. A center fixing pin passes through the center of the wire winding tube and is mounted on the fixed pin seat by a positioning screw. A limit switch is installed on the limit switch shaft. The limit switch and the wire winding motor are connected to form an electrical circuit.

[0005] A further design step is to install a flow valve on the cylinder.

[0006] A further design feature is the addition of a central fixing pin groove at the pin tip.

[0007] A further design feature is the use of serrated edges on the lower end of the wound tube.

[0008] A further design feature is that the inner diameter of the serrated part at the bottom of the coiled tube is twice the diameter of the filament top wire, which is larger than the diameter of the central fixing pin.

[0009] The advantages of this utility model are: 1. This bending machine changes the previous front and rear oblique push type to an up and down vertical wire winding mechanism. The center fixing pin presses the center line from top to bottom and is bent into a C-shaped bend by rotating the wire winding tube.

[0010] 2. After bending using this bending tool, the set screw forms a C-shape, greatly increasing the contact area with the rivet and effectively improving product quality.

[0011] 3. When using this bending tool, the set screw can be left a little longer. This avoids the phenomenon that it is easy to not bend when it is too short, and also avoids the phenomenon that the rivet tip will hit the inside of the copper head, thus eliminating the problems of poor contact and no light.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] like Figures 1-5 As shown, a filament bending device for a lamp head heating machine comprises a bracket mounted on a lamp head base 25 and a filament winding mechanism. The bracket is mounted on the lamp head base 25, and the filament winding mechanism is mounted on the bracket. The bracket includes: a base 1, a vertical shaft 2, a three-way connector 3, a limit switch shaft 4, a horizontal / vertical conversion seat 6, and a cylinder base plate shaft 7. The base 1 is mounted on the lamp head base 25, and the vertical shaft 2 is mounted on the base 1. The limit switch shaft 4 is horizontally mounted on the middle of the vertical shaft 2 via the three-way connector 3, and the upper part of the vertical shaft 2 is connected via... The horizontal-vertical conversion seat 6 is horizontally mounted with the cylinder base plate shaft 7; the top wire winding mechanism includes: a cylinder base plate frame 8, a cylinder 9, a fixed base plate 11, a gear 12, a winding motor 13, upper support seats 14 and 18 for the winding tube, a fixed needle seat 15, a central fixed needle 16, a winding tube 17, a lower support seat 18 for the winding tube, a tension spring 19, an upper bearing 20, a lower bearing 21, and a motor bracket 22; the cylinder base plate frame 8 is mounted on the cylinder base plate shaft 7, with the bottom surface of the cylinder base plate frame 8 suspended downwards. A hanging cylinder 9 is mounted on a fixed base plate 11. The bottom surface of the fixed base plate 11 is connected to one end of a tension spring 19 via a first tension spring hook 26. The other end of the tension spring 19 is connected to a second tension spring hook 27 located on the baking head base 25. A wire-winding motor 13 is mounted on the top surface of the fixed base plate 11 via a motor bracket 22. A wire-winding tube upper bracket 14 is mounted on the housing of the wire-winding motor 13. A wire-winding tube lower bracket 18 is mounted on the fixed base plate 11. The wire-winding tube 17... The upper bearing 20 and the lower bearing 21 are mounted on the upper support seat 14 and the lower support seat 18 of the winding tube. The gear 12 is fixed on the winding tube 17 by the positioning screw. The gear 12 meshes with the shaft gear of the winding motor 13. The fixed pin seat 15 is mounted on the housing of the winding motor 13. The center fixed pin 16 passes through the center of the winding tube 17 and is mounted on the fixed pin seat 15 by the positioning screw. The limit switch 5 is mounted on the limit switch shaft 4. The limit switch 5 and the winding motor 13 are connected to form an electrical circuit.

[0016] A further design feature is the installation of a flow valve 10 on cylinder 9.

[0017] A further design feature is the addition of a central fixing pin groove 23 at the tip of the central fixing pin 16.

[0018] A further design feature is that the lower end of the wound tube 17 is designed with serrated edges 24.

[0019] A further design feature is that the inner diameter of the serrated part at the bottom of the coiled tube is twice the diameter of the filament top wire, which is larger than the diameter of the central fixing pin.

[0020] When there is no pressurized air in the flow valve 10, the cylinder 9 is pulled downward by the tension spring 19, and the center fixing pin 16 and the winding tube 17 are inserted downward into the center hole of the copper head and pressed tightly. At this time, the fixed base plate 11 presses against the limit switch 5, connects the circuit, and starts the winding motor 13 to rotate. The shaft gear of the motor drives the gear 12 of the winding tube 17 to rotate. The winding tube sawtooth 24 at the lower end of the winding tube drives the top screw to rotate. The top screw rotates to the center fixing pin groove 23. Because the center fixing pin 16 is tightened by the tension spring 19 of the fixed base plate, the top screw does not move under the action of the center fixing pin groove 23. The top screw is wound into a C-shape by the winding tube sawtooth 24 at the lower end of the winding tube 17, which is larger than the copper head rivet hole but smaller than the outer circle of the rivet. When the flow valve 10 of the cylinder 9 is filled with pressurized air, the cylinder 9 rises upward, the winding motor 13 stops, and enters the next station, and so on.
