[0066] Hereinafter, with reference to FIGS. 2 to 13, the operation of using an oven door handle manufacturing device (100) according to one embodiment of the present invention will be described.

[0067] First, a plurality of handlebars (h) are mounted on the first mounting section (120a). A fitting operation can be performed to attach end caps (c) to the side ends of the handlebars (h) mounted on the first mounting section (120a). This fitting operation may be performed manually by a worker or through a separate fitting device. Before the fitting operation, a silicone injection operation may be performed by injecting silicone into the side ends of the handlebars (h). That is, after injecting a predetermined amount of silicone into each of the two sides of the handlebars (h), the fitting operation for the end caps (c) can be performed. The handlebars (h), having completed the silicone injection operation and the fitting operation of the end caps (c) on the side ends, are mounted on the first mounting section (120a) and remain in a waiting state for movement to the second mounting section (120b).

[0068] Afterwards, with the handlebar (h) having completed the fitting of the end cap mounted on the first mounting part (120a), the handlebar (h) mounted on the first mounting part (120a) is moved to the second mounting part (120b) and mounted by the handlebar moving means (130).

[0069] Specifically, the first moving member (141) is raised by the driving of the lifting drive unit (165) to push upward the plurality of handlebars (h) mounted on the first mounting unit (120a) so that they are separated from the first mounting unit (120a), and then the first moving member (141) moves to the upper space of the second mounting unit (120b) by the driving of the front and rear driving unit (155), and then the first moving member (141) is lowered by the driving of the lifting drive unit (165) so that the plurality of handlebars (h) are moved and mounted on the second mounting unit (120b).

[0070] At this time, as shown in FIG. 9, the handlebar fixing means (170) is in a state where the rotating plates (171) on both sides are spread apart. When a plurality of handlebars (h) are moved and mounted from the first mounting part (120a) to the second mounting part (120b), the handlebar fixing means (170) is driven by the front and rear driving part (155) so that the rotating plates (171) on both sides are closed, and the pressing member (173) presses both ends of the handlebar (h) as shown in FIG. 8 to prevent movement of the handlebar (h) and to prevent the end cap (c) fitted to both ends of the handlebar (h) from coming off the handlebar (h).

[0071] In this state, a worker can use a power tool to fasten a screw (screw) into the handle bar (h) through the side, thereby performing a screw connection operation in which the side end of the handle bar (h) and the end cap (c) are joined.

[0072] When the manufacturing of the handle bar (h) is completed by completing the piece joining operation in this way, the second moving member (143) is raised by the driving of the lifting drive unit (165) to push the plurality of handle bars (h, handle bars with completed piece joining operation) mounted on the second mounting unit (120b) upward so that they are separated from the second mounting unit (120b), and then the second moving member (143) moves to the upper space of the third mounting unit (120c) according to the driving of the front and rear driving unit (155), and then the second moving member (143) is lowered by the driving of the lifting drive unit (165) so that the plurality of handle bars (h) are moved and mounted on the third mounting unit (120c).

[0073] In the present invention, as shown in FIG. 12, the end cap fitting operation is completed and a plurality of handlebars (h1) are mounted on the first mounting part (120a) and are waiting. When the piece joining operation is completed for the plurality of handlebars (h2) mounted on the second mounting part (120b), the first moving member (141) and the second moving member (143) are both raised by the driving of the lifting drive unit (165), and the handlebars (h1) mounted on the first mounting member (120a) and the handlebars (h2) mounted on the second mounting part (120b) are separated upwards from the first mounting part (120a) and the second mounting part (120b) at once. Then, according to the driving of the front and rear drive unit (155), the first moving member (141) moves the plurality of handlebars (h1) from the first mounting part (120a). After moving to the upper space of the first mounting section (120b), the second moving member (143) moves the plurality of handle bars (h2) together from the second mounting section (120b) to the upper space of the third mounting section (120c), and then the first moving member (141) and the second moving member (143) are lowered by the driving of the lifting drive unit (165) so that, as shown in FIG. 13, the plurality of handle bars (h1) that were seated on the first moving member (141) are moved and seated on the second mounting section (120b), and the plurality of handle bars (h2) that were seated on the second moving member (143) are moved and seated on the third mounting section (120c).

[0074] Thus, the present invention allows the handle bar (h1) with the end cap fitting completed, mounted on the first mounting part (120a), and the handle bar (h2) with the screw joining completed, mounted on the second mounting part (120b), to be lifted upwards at once, separated and moved from the first mounting part and the second mounting part (120a, 120b), and then moved and mounted on the second mounting part and the third mounting part (120b, 120c), thereby greatly improving work efficiency.

[0075] In particular, the present invention allows for the fixation of a plurality of handle bars (h2) mounted on the second mounting part (120b) by pressing them together from both sides at once so that the handle bars (h2) do not move and the fitting end cap is not separated from the handle bars (h2), thereby enabling the fitting of the end cap without error in the fitting position and allowing for stable fitting, which can improve the precision and efficiency of the work.

[0076] Meanwhile, referring to FIG. 2, the oven door handle manufacturing device (100) of the present invention may further be configured with a silicone gun holder (210) for mounting a silicone gun (g) for injecting silicone into the inner side of the handle bar (h) mounted on the first mounting part (120a) on one side of the front part of the main body frame (110).

[0077] The operator can remove the silicone gun (g) from the silicone gun holder (210), inject silicone into each side end of the plurality of handle bars (h) mounted on the first mounting part (120a), and then attach the end cap (c) to the side end of the handle bar (h) to perform the end cap attachment operation.

[0078] Additionally, the present invention may further configure a component shelf (220) spaced apart at a predetermined distance from the upper part of the main body frame (110). The component shelf (220) may be fixedly installed by installing a bracket (222) on the upper frame (112) of the main body frame (110) and installing the component shelf (220) on the bracket (222).

[0079] The parts shelf (220) is configured to be divided into multiple separate spaces by partitions, and can place a piece tray (230) in which multiple pieces(s) are stored in rows and columns. On both sides of the parts shelf (220), a tray mounting stand (240) can be further configured to allow the piece tray (230) to be seated, thereby facilitating the piece assembly work with the pieces stored in the piece tray (230). Although not illustrated, the parts shelf (220) can be used not only for parts such as pieces, but also for parts such as a finishing cap (c) that is fitted and connected to the side end of a handle bar (h).

[0080] Additionally, a pair of vertical bars (252) are vertically connected and installed in the central part of the parts shelf (220), and a tool hanger (250) may be further configured by connecting the upper ends of the pair of vertical bars (252) to hang a power tool (k) used during piece assembly work, with tool hanger holes (255) formed on both ends. Although not illustrated, the power tool (k) may be connected to the tool hanger holes (255) of the tool hanger (250) by means of a connecting means such as a reel wire or a rope, so that the power tool (k) can be hung from the tool hanger (250) for use.

[0082] Although the present invention has been illustrated and described above in relation to preferred embodiments to illustrate the principles of the invention, the invention is not limited to the configuration and operation as illustrated and described. Rather, those skilled in the art will understand that numerous changes and modifications to the invention are possible without departing from the spirit and scope of the appended claims. Accordingly, all such appropriate changes, modifications, and equivalents should be considered to be within the scope of the invention. Explanation of the symbols
