[0031] During hot melting, the workpiece is fixed on the product positioning fixture 400, and then the momentary switch 600 is started. After receiving the start signal, the controller controls the transverse movement mechanism 500 to move the product positioning fixture 400 and the workpiece on the product positioning fixture 400 to the bottom of the hot melt gun 200, so that the hot melt gun 200 is aligned with the hot melting point of the workpiece, and then the lifting mechanism 300 is controlled to drive the hot melt gun 200 to move downward, and the workpiece is hot-melted by the hot melt gun 200. After completion, the lifting mechanism 300 is controlled to drive the hot melt gun 200 to return, and the transverse movement mechanism 500 is controlled to drive the product positioning fixture 400 and the workpiece on the product positioning fixture 400 to return to the manual operation position, and then the worker removes the workpiece on the product positioning fixture 400. Therefore, the present application can realize the automation of the hot melting process of the junction box assembly, and the operation is more convenient and quick.

[0032] Reference Figure 1 and Figure 4The frame 100 includes a base plate 110, a rear mounting plate 120 disposed on the upper side of the base plate 110, two side support plates 130 disposed on the upper side of the base plate 110 and disposed on the front side of the rear mounting plate 120 opposite to each other, and a guard plate 140 disposed on the upper side of the base plate 110 and connected between the front sides of the two side support plates 130. The hot melt gun 200 extends into the space surrounded by the rear mounting plate 120, the two side support plates 130 and the guard plate 140. The lower part of the guard plate 140 is provided with a door hole 141 for the product positioning tooling 400 and the workpiece mounted on the product positioning tooling 400 to pass through. In this embodiment, the manual operation position and the hot melt position can be separated by the guard plate 140, which can prevent workers from touching the gun tip of the hot melt gun 200 and getting burned, thereby ensuring safe use. At the same time, a door opening 141 is set at the lower part of the guard plate 140 to meet the requirements of the product positioning tool 400 and the workpiece installed on the product positioning tool 400 to move between the manual operation position and the hot melt position.

[0033] Reference Figure 1 , Figure 3 and Figure 4 The lifting mechanism 300 includes a first slide rail 310 fixed on the frame 100 and extending vertically in the up-down direction, a first slider 320 slidably mounted on the first slide rail 310, and a power unit for driving the first slider 320 to slide along the first slide rail 310. The hot melt gun 200 is fixed on the first slider 320 through a connecting member 330. The lifting and lowering of the hot melt gun 200 is precisely guided by the guide rail and the slider, which can prevent the hot melt gun 200 from deflecting. In this embodiment, the power unit specifically includes a lifting cylinder 340, and a first solenoid valve 350 connected between the lifting cylinder 340 and the air source and used to control the extension and retraction of the lifting cylinder 340. The controller is electrically connected to the first solenoid valve 350, so that the controller controls the switching of the first solenoid valve 350 to control the extension and retraction of the lifting cylinder 340, thereby controlling the hot melt gun 200 to move up and down.

[0034] Reference Figure 5 The connecting member 330 includes a first push block 331 and a hot melt gun fixing seat 332. The first push block 331 is fixed on the first slider 320. A mounting groove 3311 is provided at the front side of the first push block 331. A second slide rail 333 extending vertically is provided in the mounting groove 3311. A second slide rail 334 is slidably mounted on the second slide rail 333. The rear portion of the hot melt gun fixing seat 332 is fixed on the second slide rail 334. A buffer spring 335 is supported between the upper side of the rear portion of the hot melt gun fixing seat 332 and the upper side wall of the mounting groove 3311. The hot melt gun 200 is fixed on the front side of the hot melt gun fixing seat 332. When the hot melt gun 200 is driven to move downward to hot-melt the workpiece, the buffer spring 335 can be used for buffering, thereby reducing the impact of the hot melt gun 200 on the product surface when pressed downward.

[0035] In order to facilitate the fixing of the hot melt gun 200 on the hot melt gun fixing seat 332, the connecting piece 330 also includes a hot melt gun locking block 336, which is fixed to the front side of the hot melt gun fixing seat 332 by bolts. The front side of the hot melt gun fixing seat 332 is provided with a hot melt gun fixing seat slot 3321, and the hot melt gun locking block 336 is provided with a hot melt gun locking block slot 3361 opposite to the hot melt gun fixing seat slot 3321. The hot melt gun 200 is stuck between the hot melt gun fixing seat slot 3321 and the hot melt gun locking block slot 3361.

[0036] The transverse movement mechanism 500 includes a third slide rail 510 fixed on the frame 100 and extending horizontally in the front-to-back direction, a third slider 520 slidably mounted on the third slide rail 510, a push cylinder 530 for driving the third slider 520 to slide along the third slide rail 510, and a second solenoid valve 540 connected between the push cylinder 530 and the air source and used to control the extension and retraction of the push cylinder 530. The product positioning tooling 400 is fixed on the third slider 520, and the controller is electrically connected to the second solenoid valve 540. In this way, the controller controls the switching of the second solenoid valve 540 to control the extension and retraction of the push cylinder 530, thereby driving the product positioning tooling 400 to move. The movement of the product positioning tooling 400 is precisely guided by the guide rails and the sliders, which can prevent the hot melt position point on the workpiece from shifting.

[0037] Preferably, a magnet is provided on the piston inside the push cylinder 530, and two magnetic induction switches 550 that can sense when the magnet approaches are provided on the outside of the push cylinder 530. When the magnet approaches the two magnetic induction switches 550, the product positioning tooling 400 moves to the manual operation position and the hot melt position directly below the hot melt gun 200 respectively, and the controller is electrically connected to the two magnetic induction switches 550.

[0038] The pushing cylinder 530 of this embodiment is arranged at the rear of the product positioning tooling 400. When the controller controls the pushing cylinder 530 to drive the product positioning tooling 400 to move to the hot melt position, when the magnetic induction switch 550 on the front side of the pushing cylinder 530 detects the magnet, it sends a signal to the controller, and the controller immediately controls the pushing cylinder 530 to stop moving. When the controller controls the pushing cylinder 530 to drive the product positioning tooling 400 to move to the operating position, when the magnetic induction switch 550 on the rear side of the pushing cylinder 530 detects the magnet, it sends a signal to the controller, and the controller immediately controls the pushing cylinder 530 to stop moving. In this way, in the process of driving the product positioning tooling 400 to move forward and backward, the product positioning tooling 400 can be accurately stopped at the hot melt position and the operating position, thereby ensuring that the hot melt point on the workpiece is accurately aligned with the gun head of the hot melt gun 200.

[0039] In this embodiment, refer to Figure 1 and Figure 4There are two moment switches 600, and the two moment switches 600 must be started at the same time to trigger the start signal. During operation, the operator needs to place both hands on the two moment switches 600 to start the hot melt program, which greatly ensures the safety of the operator.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
