[0063] The film sticking unit 1 provided in the embodiment of the present application can be suitable for sticking a protective film to an electronic device accessory, such as a washing machine knob, and the protective film is stuck to the outer surface of the washing machine knob.

[0064] In the film laminating unit 1 provided in the embodiment of the present application, a feeding mechanism 12 is used to feed the protective film. The feeding mechanism 12 includes a frame 121, a feeding roller 122 and a collecting roller 123, wherein the feeding roller 122 and the collecting roller 123 are installed on the frame 121, the feeding roller 122 is used to place the protective film roll, and the collecting roller 123 is used to collect the base paper of the protective film. In addition, the feeding mechanism 12 also includes a feeding platform 124 arranged on the frame 121, the feeding platform 124 is used to carry the protective film after the base paper is peeled off, and the conveying mechanism 13 takes the protective film after the base paper is peeled off at the feeding platform 124. It is worth noting that the feeding platform 124 is made of a material with a non-sticky layer, that is, there will be no adhesion between the adhesive layer of the protective film and the feeding platform 124.

[0065] In the film laminating unit 1 provided in the embodiment of the present application, the protective film is transported by using the transport mechanism 13, specifically, the protective film is sucked by using the transport suction head 130 in the transport mechanism 13, and the transport suction head 130 can perform translational movement in the first direction, the second direction and the third direction; Figure 1a As shown, the first direction is Figure 1a The a direction in the second direction is Figure 1a The b direction in the figure is Figure 1a c direction in the assembly line; in the assembly line, the first direction corresponds to the vertical direction, and the second direction is the direction in which each process in the assembly line is arranged; the first direction, the second direction and the third direction are perpendicular to each other.

[0067] In the film sticking unit 1 provided in the embodiment of the present application, a positioning mechanism 11 is used to place the electronic device accessory to which the protective film is to be attached and to position the electronic device accessory; that is, the position of the electronic device accessory in the positioning mechanism 11 is accurately determined, which is conducive to the conveying mechanism 13 accurately attaching the protective film to the electronic device accessory, thereby improving assembly accuracy and assembly efficiency.

Thus, the carrier plate 111 is lifted by the lifting and fixing assembly 113 at its bottom, and the carrier plate 111 is limited by the positioning baffle 112 at its top, so that the carrier plate 111 will not be displaced in the first direction, ensuring the accuracy of the position of the carrier plate 111 in the first direction.

[0097] In the electronic device accessory assembly production line provided in the embodiment of the present application, since the film sticking unit 1 is included, it can accurately stick the protective film to the electronic device accessory, ensuring assembly accuracy and assembly efficiency, and having a high degree of automation.

[0098] Reference Figure 2 As shown, in one embodiment, according to the process sequence of the assembly production line, the preceding assembly unit 2 sequentially includes a rotating component assembly unit 21, a communication assembly unit 22, an oiling unit 23, a core assembly unit 24, a knob assembly unit 25, a first PCB assembly unit 26 and a frame assembly unit 27;

[0099] According to the process sequence of the assembly production line, the subsequent assembly unit 3 includes a button assembly unit 31 , a second PCB assembly unit 32 , a screw assembly unit 33 and a testing unit 34 in sequence.

[0100] In this specific example, before the protective film is attached to the electronic device accessories, the electronic device accessories sequentially pass through the rotating component assembly unit 21, the communication assembly unit 22, the oiling unit 23, the core assembly unit 24, the knob assembly unit 25, the first PCB assembly unit 26 and the frame assembly unit 27; after the protective film is attached to the electronic device accessories, the electronic device accessories sequentially pass through the button assembly unit 31, the second PCB assembly unit 32, the screw assembly unit 33 and the testing unit 34. The assembly production line is compact and reasonable, and has a high degree of automation.

[0101] Reference Figure 2 As shown, in one embodiment, at least the rotating component assembly unit 21, the core assembly unit 24, the knob assembly unit 25, the first PCB assembly unit 26 and the second PCB assembly unit 32 are provided with an automatic feeding bin 4.

[0102] In this specific example, by providing an automatic feeding bin 4, the feeding speed of the assembly production line is increased, thereby ensuring the production efficiency of the entire line.

[0103] Reference Figure 3a-3eAs shown, in one embodiment, the automatic feeding bin 4 includes a first lifting mechanism 41, a second lifting mechanism 42 and a tray separation mechanism 43, the first lifting mechanism 41 and the second lifting mechanism 42 are arranged along the second direction, and the first lifting mechanism 41 and the second lifting mechanism 42 can both move up and down along the first direction;

[0104] The tray separation mechanism 43 is disposed above the first lifting mechanism 41 and the second lifting mechanism 42, and the tray separation mechanism 43 can move translationally along the second direction;

[0105] The first lifting mechanism 41 carries a plurality of trays in the first state and rises to a position corresponding to the tray separation mechanism 43 along the first direction. The tray separation mechanism 43 moves translationally close to the first lifting mechanism 41 along the second direction. The tray separation mechanism 43 receives the tray in the first state at the top layer, and the first lifting mechanism 41 drives the remaining trays in the first state to descend.

[0106] The tray dividing mechanism 43 drives the first-state material tray on the top layer to move along the second direction close to the second lifting mechanism 42, and the first-state material tray on the top layer is switched to the second-state material tray under the action of external equipment. When the first-state material tray on the top layer is switched to the second-state material tray, the second lifting mechanism 42 rises and receives the second-state material tray.

[0107] In this specific example, the external device may be, for example, a material taking device, and the material tray in the first state is a full material tray, and the material tray in the second state is an empty material tray; if the external device is a material discharging device, the material tray in the first state is an empty material tray, and the material tray in the second state is a full material tray. The following is an example in which the material tray in the first state is a full material tray and the material tray in the second state is an empty material tray.

[0108] Generally, before the first lifting mechanism 41 drives the stacked multiple full trays to perform an upward movement, the stacked multiple full trays enter from the rear end of the loading compartment and then translate along the third direction to the front end of the loading compartment through the conveyor belt.

[0109] Then the first lifting mechanism 41 drives the multiple stacked full trays to rise to the height position where the tray separating mechanism 43 is located. The tray separating mechanism 43 first moves horizontally along the second direction to approach the full trays. After the tray separating mechanism 43 moves into position, it receives the full tray on the top layer. At the same time, the first lifting mechanism 41 drives the remaining full trays to descend, thereby separating the full tray on the top layer from the other full trays.

[0110] Afterwards, the tray-separating mechanism 43 drives the full tray on the top layer to move in the second direction and gradually approach the position of the second lifting mechanism 42. During this process, the external material-retrieving device retrieves the materials placed in the full tray on the top layer. For example, the tray-separating mechanism 43 moves in the second direction one step, and the material-retrieving device retrieves a row of materials until all the materials are taken away, and the full tray on the top layer is converted into an empty tray. Then, the second lifting mechanism 42 rises and receives the empty tray, and at the same time, the tray-separating mechanism 43 releases the empty tray; finally, the second lifting mechanism 42 drives the empty tray to move downward for a certain distance to wait for the next empty tray.

[0111] The unloading compartment where the second lifting mechanism 42 is located is also provided with a conveyor belt that can transport along the third direction; after the second lifting mechanism 42 has taken over all the empty material trays, the second lifting mechanism 42 drives the stacked multiple empty material trays to first move downward, and then, under the action of the conveyor belt, the empty material trays are transported from the front end to the rear end of the unloading compartment, thereby completing the entire feeding operation of the automatic feeding bin 4.

[0112] The automatic feeding bin 4 has a compact structure, a reasonable layout, and a high degree of automation and working efficiency.

[0113] Reference Figure 3a-3e As shown, in one embodiment, the disk separation mechanism 43 includes a translation driving member 431, a translation plate 432 and a positioning member 433, and the translation driving member 431 is connected to the translation plate 432 and can drive the translation plate 432 to translate along the second direction;

[0114] A hollow area 4320 is provided in the middle of the translation plate 432, and the positioning member 433 is installed on the translation plate 432. Two positioning members 433 are provided, and the two positioning members 433 are arranged relatively on both sides of the hollow area 4320 along the second direction; the positioning member 433 is used to be connected with the material tray for positioning.

[0115] In this specific example, the translation driving member 431 is used to drive the translation plate 432 to translate along the second direction; optionally, the translation driving member 431 can be, for example, an electric cylinder, a conveyor belt, a motor screw mechanism, etc.

[0116] Driven by the translation drive member 431, the translation plate 432 moves to a position where the central hollow area 4320 corresponds to the full tray, and the topmost full tray rises into the hollow area 4320, and then is positioned and connected by two positioning members 433 from both sides of the full tray to clamp the full tray.

[0117] Reference Figure 3a-3eAs shown, in one embodiment, the positioning member 433 includes a positioning cylinder 4331 and a positioning tooth 4332, and the positioning cylinder 4331 and the positioning tooth 4332 are connected, and the positioning cylinder 4331 can drive the positioning tooth 4332 to telescopically move along the second direction. When the positioning tooth 4332 is extended along the second direction, the positioning tooth 4332 is positioned and connected to the material tray.

[0118] In this specific example, when the full tray needs to be clamped, the positioning cylinder 4331 drives the positioning tooth 4332 to extend, and the positioning tooth 4332 is clamped into the positioning clamping hole set on the full tray, and the positioning teeth 4332 of the two positioning members 433 clamp the full tray.

[0119] Reference Figure 3a-3e As shown, in one embodiment, the tray separation mechanism 43 further includes a positioning block 434, and the positioning block 434 is installed on the translation plate 432 and located in the hollow area 4320, and the positioning block 434 is used to abut the material tray.

[0120] In this specific example, two positioning blocks 434 are provided, and the hollow area 4320 is roughly rectangular. The two positioning blocks 434 are respectively located at the diagonal positions of the hollow area 4320, and the two positioning blocks 434 respectively abut the two top corners of the full tray, so that the tray separation mechanism 43 can more stably and reliably separate the topmost full tray from the remaining full trays.

[0121] Reference Figure 3a-3e As shown, in one embodiment, the automatic feeding bin 4 also includes a bottom supporting mechanism 44, and the bottom supporting mechanism 44 is arranged close to the tray dividing mechanism 43, and the bottom supporting mechanism 44 can move up and down along the first direction and move horizontally along the second direction; when the tray dividing mechanism 43 receives the uppermost tray in the first state, and the first lifting mechanism 41 drives the remaining trays in the first state to descend, the bottom supporting mechanism 44 abuts against the bottom of the uppermost tray in the first state.

[0122] In this specific example, when the tray dividing mechanism 43 clamps the topmost full tray and the first lifting mechanism 41 drives the remaining full trays to descend, the bottom supporting mechanism 44 first moves along the second direction to below the hollow area 4320. At this time, the bottom supporting mechanism 44 moves into position along the second direction, and then the bottom supporting mechanism 44 rises along the first direction to abut against the bottom of the full tray clamped by the tray dividing mechanism 43. The bottom supporting mechanism 44 supports the full tray from the bottom. In the process that the tray dividing mechanism 43 drives the full tray to move translationally toward the second lifting mechanism 42, the bottom supporting mechanism 44 synchronously moves translationally along the second direction. During this process, the bottom supporting mechanism 44 always supports the full tray from the bottom to prevent the full tray from falling off.

[0123] When the full tray is converted into an empty tray and needs to be taken up by the second lifting mechanism 42 , the bottom supporting mechanism 44 first descends a certain distance in the first direction to separate from the empty tray, and then moves a certain distance in the second direction to avoid the second lifting mechanism 42 .
