DETAILED DESCRIPTION OF THE INVENTION

[0011] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0012] For the sake of convenience, the following definitions are used for the terms "front," "rear," "left," "right," "upper," and "lower" as shown in Figures 1 to 12. The "front-rear direction," "left-right direction," and "up-down direction" are perpendicular to one another. The "left-right direction" corresponds to the "transport direction" of the present invention.

[0013] FIG. 1 is a block diagram showing one embodiment of an applicator 1 of the present invention. The applicator 1 shown in FIG. 1 is an apparatus that applies a coating material 101 made of a UV-curable resin to an end of a terminal-attached electric wire 10 (workpiece). The terminal-attached electric wire 10 includes an electric wire 102 and a terminal 103 attached to the end of the electric wire 102. The electric wire 102 has a coating 102A stripped from the end to expose a wire bundle 102B. The terminal 103 is crimped to the coating 102A and wire bundle 102B exposed at the end. The applicator 1 covers the wire bundle 102B exposed from the end of the electric wire 102 with coating material 101, thereby preventing corrosion at the crimped joint between the wire bundle 102B and the terminal 103.

[0014] The coating device 1 includes a conveying section 2, an electric wire supplying section 3 that supplies terminal-attached electric wires 10 to the conveying section 2, an imaging section 4 that images the terminal-attached electric wires 10 conveyed by the conveying section 2, an application section 5 that applies coating agent 101 to the ends of the terminal-attached electric wires 10 conveyed by the conveying section 2, a UV irradiation section 6 (irradiation section) that irradiates the applied coating agent 101 with UV light (curing light), and a control section 7 that controls these sections 3 to 6.

[0015] The above-mentioned electric wire supply unit 3, imaging unit 4, coating unit 5, and UV irradiation unit 6 are arranged side by side in the left-right direction. From right to left, they are arranged in the order of electric wire supply unit 3, imaging unit 4, coating unit 5, and UV irradiation unit 6.

[0016] First, the configuration of the transfer unit 2 will be described. As shown in Fig. 2 and Fig. 3, the transfer unit 2 of this embodiment has four rear electric wire chucks 21 (holding units) and four front electric wire chucks 22. The four rear electric wire chucks 21 are arranged side by side at equal intervals in the left-right direction. The four rear electric wire chucks 21 are provided so as to be movable in the left-right direction between a first position and a second position.

[0017] 2 and 3 , at the first position, the four rear electric wire chucks 21 face the electric wire supply unit 3, the imaging unit 4, the coating unit 5, and the UV irradiation unit 6 in the front-rear direction. At the second position, the rightmost rear electric wire chuck 21 faces the imaging unit 4 in the front-rear direction, the second leftmost rear electric wire chuck 21 faces the UV irradiation unit 6 in the front-rear direction, and the leftmost rear electric wire chuck 21 is located to the left of the UV irradiation unit 6.

[0018] 3, the four front electric wire chucks 22 are arranged forward in the front-rear direction (on the side of the electric wire supply unit 3, the imaging unit 4, the coating unit 5, and the UV irradiation unit 6) of the four rear electric wire chucks 21. The four front electric wire chucks 22 are arranged side by side at equal intervals in the left-right direction and face the electric wire supply unit 3, the imaging unit 4, the coating unit 5, and the UV irradiation unit 6 in the front-rear direction. The four front electric wire chucks 22 do not move in the left-right direction.

[0019] Next, the configurations of the rear electric wire chuck 21 and the front electric wire chuck 22 will be described. The four rear electric wire chucks 21 have the same configuration. The rear electric wire chuck 21 has a cubic main body 23 and a pair of chucks 24, 24 that are attached to the main body 23 so as to be able to open and close freely and that clamp and hold the terminal-fitted electric wire 10 from the left and right directions.

[0020] The front electric wire chucks 22 have the same configuration as the rear electric wire chucks 21, so detailed description thereof will be omitted here. The main bodies 23 of the four rear electric wire chucks 21 are attached to a cylinder (not shown) that moves in the left-right direction.

[0021] The conveying operation of the conveying unit 2 configured as described above will be described. The electric wire with terminals 10 is held (held in the correct position) by the electric wire supplying unit 3 in the rightmost rear electric wire chuck 21 and front electric wire chuck 22. Next, the front electric wire chuck 22 is opened, and the rear electric wire chuck 21 is moved from the first position to the second position. As a result, the electric wire with terminals 10 is conveyed to the imaging unit 4, and can be held by the front electric wire chuck 22, which is the second from the right and arranged opposite the imaging unit 4. Thereafter, the rear electric wire chuck 21 is opened and returned from the second position to the first position, and the electric wire with terminals 10 can be held by the rear electric wire chuck 21, which is the second from the right. By repeating this process, the electric wire with terminals 10 can be conveyed to the electric wire supplying unit 3, the imaging unit 4, the coating unit 5, and the UV irradiation unit 6 in that order.

[0022] The electric wire supply unit 3 has a work setting jig (not shown). When an operator inserts an end of the terminal-fitted electric wire 10 into the work setting jig and abuts against a positioning wall inside the work setting jig, the front electric wire chuck 22 closes. This allows the front-to-rear position of the terminal 103 of the terminal-fitted electric wire 10 to be positioned. In this embodiment, after the front electric wire chuck 22 is closed, when the operator presses an operation button (not shown), the rear electric wire chuck 21 closes and the front electric wire chuck 22 opens. Thereafter, the rear electric wire chuck 21 moves to a second position and transports the terminal-fitted electric wire 10 to the imaging unit 4.

[0023] The imaging unit 4 has a camera (not shown) attached facing downward. When the electric wire with terminal 10 is conveyed to the imaging unit 4 and held by the front electric wire chuck 22 facing the imaging unit 4 in the front-rear direction, the terminal 103 comes within the imaging range of the camera.

[0024] 4, the coating unit 5 has a discharge unit 51 provided with a discharge nozzle (not shown) that discharges the coating agent 101, and a pre-irradiation unit 52 provided with a UV light source (not shown) that pre-irradiates UV light LL. The discharge unit 51 and the pre-irradiation unit 52 are fixed to a mounting base 53. In this embodiment, the discharge unit 51 and the pre-irradiation unit 52 are attached to the mounting base 53 side by side in the left-right direction.

[0025] 5, the mounting base 53 is provided so as to be movable in the up-down, left-right, and front-back directions by an up-down cylinder 54, a left-right cylinder 55, and a front-back cylinder 56 (movement mechanism). By moving the mounting base 53 up-down, left-right, and front-back, the discharge unit 51 and the pre-irradiation unit 52 simultaneously move up-down, left-right, and front-back.

[0026] The UV irradiation unit 6 has a UV light source (not shown) that irradiates UV light. When the terminal-fitted wire 10 is transported to the UV irradiation unit 6 and held by the front wire chuck 22 that faces the UV irradiation unit 6 in the front-rear direction, the terminal 103 enters the irradiation range of the UV light source. In this embodiment, the UV light source of the pre-irradiation unit 52 has a lower output than the UV light source of the UV irradiation unit 6.

[0027] The control unit 7, which functions as a coating control unit and a transport control unit, is composed of a microcomputer that operates according to a program stored in the memory unit, and is responsible for overall control of the coating device 1. In the coating mode, the control unit 7 transports the terminal-attached electric wire 10 through the electric wire supply unit 3, the imaging unit 4, the coating unit 5, and the UV irradiation unit 6 in this order, and sequentially supplies the terminal-attached electric wire 10, applies the coating agent 101, and irradiates it with UV light. The control unit 7 also measures the terminal positions from the images of the terminals 103 captured by the imaging unit 4, determines the application position of the coating agent 101 based on the measured terminal positions, and controls the movement of the discharge unit 51 to apply the coating agent 101 to the determined application position (i.e., the position that covers the exposed wire bundle 102B).

[0028] Next, the operation of the coating apparatus 1 outlined above will be described with reference to the flowchart in Fig. 6. When an operator inserts a terminal-fitted electric wire 10 into the work set jig, the front electric wire chuck 22 closes. This allows the terminal-fitted electric wire 10 to be supplied to the conveying unit 2 (S1). When the operator operates the operation button, the control unit 7 controls the conveying unit 2 to convey the terminal-fitted electric wire 10 held by the electric wire supplying unit 3, the imaging unit 4, and the coating unit 5 to the adjacent imaging unit 4, coating unit 5, and UV irradiation unit 6 on the left side (downstream in the conveying direction).

[0029] As a result, the terminal-fitted wire 10 held by the wire supply unit 3 is transported to the imaging unit 3. When the terminal-fitted wire 10 is transported to the imaging unit 3, the control unit 7 causes the imaging unit 3 to capture an image of the terminal-fitted wire 10 and measure the terminal position (S2). When the worker operates the operation button again, the terminal-fitted wire 10 held by the imaging unit 3 is transported to the coating unit 5. The control unit 7 controls the up-down cylinder 54, the left-right cylinder 55, and the front-rear cylinder 56 to vertically oppose the discharge unit 51 and the terminal 103 of the terminal-fitted wire 10 as shown in FIG. 7, and causes the coating agent 101 to be discharged from the discharge unit 51 (S3).

[0030] In S3, the control unit 7 controls the left and right cylinders 55 and the front and rear cylinders 56 to move the discharge unit 51 back and forth and left and right while discharging the coating agent 101. At this time, the control unit 7 determines the application position of the coating agent 101 based on the terminal position measured in S2, and applies the coating agent 101 to the determined application position.

[0031] Thereafter, if the operator does not press the operation button within a predetermined time (e.g., 2 seconds) after application (Y in S4), the control unit 7 proceeds to S5. In S5, the control unit 7 controls the up-down cylinder 54, the left-right cylinder 55, and the front-rear cylinder 56 to vertically oppose the pre-irradiation unit 52 and the terminals 103 of the terminal-fitted electric wire 10 as shown in FIG. 8, and causes the pre-irradiation unit 52 to pre-irradiate with UV light. Thereafter, when the operator presses the operation button, the terminal-fitted electric wire 10 held in the application unit 5 is transported to the UV irradiation unit 6. If the operation button is pressed during pre-irradiation, the control unit 7 transports the terminal-fitted electric wire 10 after the pre-irradiation has ended.

[0032] In response to this, if the operation button is operated within a predetermined time after application (N in S4), the control unit 7 transports the electric wire with terminal 10 without performing preliminary irradiation, and transports the electric wire with terminal 10 held in the application unit 5 to the UV irradiation unit 6. When the electric wire with terminal 10 is transported to the UV irradiation unit 6, the control unit 7 irradiates it with UV light (S6) and finishes applying the coating agent 101.

[0033] According to the above-described embodiment, both the application of the coating agent 101 and the pre-irradiation of UV light can be performed on the terminal-fitted wires 10 transported to the coating unit 5. As a result, even if there is a delay in the transport unit 2, the pre-irradiation can reduce dripping of the coating agent 101.

[0034] According to the above-described embodiment, the discharge unit 51 and the pre-irradiation unit 52 are attached to the mounting base 53, and the mounting base 53 is moved up and down, left and right, and front and rear cylinders 54 to 56. Both the discharge unit 51 and the pre-irradiation unit 52 can be moved using the up and down, left and right, and front and rear cylinders 54 to 56. This allows, with a simple configuration, to both apply the coating agent 101 and pre-irradiate the UV light LL to the terminal-attached electric wire 10 transported to the coating unit 5.

[0035] According to the above-described embodiment, if the electric wire with terminal 10 can be transported toward the UV irradiation unit 6 within a predetermined time, pre-irradiation by the pre-irradiation unit 52 is not performed. As a result, pre-irradiation is not performed on all of the electric wire with terminal 10 transported to the coating unit 5, and therefore the time from when the coating agent 101 is applied to the electric wire with terminal 10 until when it is irradiated by the UV irradiation unit 6 can be shortened.

[0036] The present invention is not limited to the above-described embodiments, and can be appropriately modified, improved, etc. Furthermore, the material, shape, size, number, location, etc. of each component in the above-described embodiments are arbitrary and not limited as long as they can achieve the present invention.

[0037] According to the above-described embodiment, the electric wire with terminal 10 is used as the workpiece, but the present invention is not limited to this. The workpiece does not have to be the electric wire with terminal 10 as long as it is coated with the coating material 101.

[0038] According to the embodiment described above, the transfer unit 2 has four rear wire chucks 21, but the number of rear wire chucks 21 is not limited to four.

[0039] According to the above-described embodiment, if the electric wire with terminal 10 is coated with the coating agent 101 and then transported to the UV irradiation unit 6 within a predetermined time, pre-irradiation is not performed in the coating unit 5, but this is not limited thereto. Pre-irradiation may be performed every time the electric wire with terminal 10 is transported to the coating unit 5 and coated with the coating agent 101.
