The second visual inspection unit 512 locates the first heating pack as a moving reference. The material transfer assembly 52 adjusts the position of the radiator inserted with the heating pack. The point pressing assembly 51 presses the heating packs into the reserved grooves of the radiator in sequence to complete the pressing work. After the pressing is completed, the second clamping jaw assembly 32 is used to transfer the pressed radiator to the carrier unit 221 for backward transmission.

[0040] Further, if Figure 1-Figure 7 As shown, the carrying mechanism 2 includes a conveying component 21 disposed on the platform 1 and a bearing component 22 disposed on the conveying component 21; The conveying assembly 21 includes a track 211 disposed on the machine platform 1 , a chain disposed on the track 211 , and a first position sensor 212 disposed on the track 211 ; The bearing assembly 22 includes a carrier unit 221 disposed on the chain, a positioning unit 222 disposed on the carrier unit 221 and used to support the radiator, and a material box 223 placed on the carrier unit 221 and used to load the heating pack; The plate carrier unit 221 includes a bottom frame 2211 disposed on the chain and a tray 2212 disposed on the bottom frame 2211; The positioning unit 222 includes a support block 2221 disposed on the tray 2212 and used to support the radiator, and a positioning column 2222 disposed on the tray 2212 and used to position the radiator; It also includes a lifting unit 224 for lifting the bearing component 22 and detaching it from the track 211. The lifting unit 224 is divided into several groups arranged at corresponding positions on the track 211, including a first hydraulic cylinder 2241 arranged on the track 211, a lifting platform 2242 arranged on the output end of the first hydraulic cylinder 2241, several groups of lifting columns 2243 arranged on the lifting platform 2242, and a lifting groove 2244 opened on the bottom frame 2211 and adapted to the lifting column 2243. The lifting unit 224 lifts the carrier unit 221 to ensure the positioning accuracy of each grabbing.

[0041] The first position sensors 212 are divided into several groups and are respectively arranged at the positions of the gluing mechanism 4 and the pressing mechanism 5 .

[0042] In this embodiment, through the cooperation of the conveying component 21 and the supporting component 22, on the one hand, the radiator can be well positioned and supported to ensure that the radiator is placed stably, and the radiator can be driven to rise and fall through the carrier unit 221 to ensure the positioning accuracy of each grab, which is beneficial for the first clamping jaw component 31 to accurately assemble the heating pack into the reserved groove of the radiator, thereby improving the assembly accuracy; on the other hand, the stop position of the carrier unit 221 on the track 211 can be automatically controlled to facilitate the gluing and pressing of the heating pack, thereby improving the effect of fully automatic gluing and pressing of the heating pack.

[0043] In detail, the material box 223 is placed on a specific position of the tray 2212, the radiator is placed on the support block 2221, and the positioning column 2222 is extended into the mounting hole of the radiator to achieve positioning support. The chain is driven by an external power source and moves the carrier unit 221 to the position of the gluing mechanism 4 and then stops. The first position sensor 212 controls the stop position of the carrier unit 221 on the track 211. The first hydraulic cylinder 2241 drives the carrier unit 221 to move up and down with the radiator through the lifting column 2243, thereby ensuring the positioning accuracy of each grabbing and facilitating the first clamping jaw assembly 31 to clamp the heating bag in the material box 223.

[0044] Further, if Figure 8-Figure 11 As shown, the first clamping jaw assembly 31 includes a mechanical arm 311 disposed on the machine platform 1, a first clamping unit 312 disposed on the mechanical arm 311 and adapted to the heating pack, and an identification unit 313 disposed on the first clamping unit 312; The identification unit 313 includes a third visual camera 3131 disposed on the power unit 3121 and a displacement sensor 3132 disposed on the outer clamping jaw 3123; The first clamping unit 312 includes a power part 3121 arranged at the end of the mechanical arm 311, a lower pressing claw 3122 arranged on the power part 3121 and pressing the heating pack into the reserved groove of the radiator, and an outer clamping claw 3123 arranged at the output end of the power part 3121 and used to clamp the side of the heating pack.

[0045] It should be noted that the power unit 3121 adopts the power part of the existing electric clamp, which can drive the outer clamp 3123 to grasp and release the heating package, or other driving structures that enable the outer clamp 3123 to grasp and release the heating package are also applicable to this embodiment.

[0046] It should also be noted that the power unit 3121 cannot drive the downward pressing claw 3122 to clamp and release, and the downward pressing claw 3122 is fixedly installed at the bottom of the power unit 3121, and the power unit 3121 can lift and lower the downward pressing claw 3122.

[0047] It is worth mentioning that when the outer clamp 3123 clamps the heating pack, due to the small size and light weight of the heating pack, the outer clamp 3123 does not need too much clamping force to clamp the heating pack; and when applying glue, during the process of the outer clamp 3123 carrying the heating pack up, the double-head moving unit 412 clamps the side of the heating pack through the scraper head 413, and since the upper parts of both sides of the heating pack are provided with lateral protrusions, the outer clamp 3123 can be hung at the lower position of the lateral protrusions to pull the heating pack up. Therefore, during the process of applying glue, the outer clamp 3123 does not need to It does not require excessive clamping force to clamp the heating pack; when assembling the heating pack into the reserved groove of the radiator, in order to insert the heating pack tightly into the reserved groove of the radiator and improve the stability of the assembly, while avoiding the outer clamping claw 3123 using a large clamping force to press the heating pack downward into the reserved groove of the radiator, the heating pack can be pressed down by the lower pressing claw 3122 to insert it tightly into the reserved groove of the radiator. Therefore, during the assembly process, the outer clamping claw 3123 does not need excessive clamping force to clamp the heating pack, so that the heating pack can be assembled with high stability and the heating pack can be avoided from being squeezed and damaged.

[0048] In this embodiment, by cooperating with the first clamping unit 312 and the identification unit 313, the heating pack can be automatically positioned and clamped for transfer, and the heating pack can be pressed and inserted into a designated position in the reserved groove of the radiator, with high assembly accuracy to prevent the heating pack from being squeezed and damaged.

After the robot arm 311 drives the heating pack to complete gluing and inspection, the robot arm 311 drives the first clamping unit 312 to move the glued heating pack to the upper position of the radiator reserved groove in sequence, and then drives the heating pack to descend into the radiator reserved groove. Then, the power unit 3121 drives the outer clamping claw 3123 to release the heating pack, and the robot arm 311 drives the heating pack to continue to descend through the first clamping unit 312, and the power unit 3121 presses the heating pack down through the pressing claw 3122 to insert it into the radiator reserved groove.

[0051] The first visual inspection unit 42 includes a first visual camera 421 disposed on the machine 1 and a defective product collection box 422 disposed on the machine 1 and used for collecting heating packs with unqualified glue coating.

[0052] In this embodiment, by cooperating with the set glue spreading component 41 and the first visual inspection unit 42, on the one hand, the impact force of the glue scraper head 413 clamping the side of the heating pack is reduced to avoid damage to the heating pack, and double-sided glue can be applied to both sides of the heating pack, and the glue is scraped from top to bottom along both sides of the heating pack.
