[0052] When the worm 304 rotates, it is convenient to drive the gear rod 307 to rotate through the vertically meshing bevel gear 306. Conversely, when the gear rod 307 rotates under the action of the main gear 308, it can also drive the worm 304 to rotate through the meshing bevel gear 306.

[0053] Embodiment 2 further optimizes the loading and unloading device for the vacuum coating machine provided in Embodiment 1. Specifically, Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the driving assembly 4 includes a mounting frame 401 which is sleeved on the outside of the connecting shaft 305, the mounting frame 401 is sleeved with the connecting shaft 305 and the gear rod 307, a driving motor 402 is fixedly installed on the middle and lower part of the mounting frame 401 away from the mounting plate 301, a worm gear 403 is arranged above the driving motor 402, connecting shafts extend from both ends of the worm gear 403, the worm gear is sleeved with the mounting frame 401, and the worm gear 403 is meshed with the worm 304 when the roller 201 is horizontal, and the extending connecting shaft at one end of the worm gear 403 is connected to the output end of the driving motor 402 through a belt.

[0054] The driving motor 402 drives the worm wheel 403 to rotate, and further drives the worm 304 meshing with the worm wheel 403 to rotate.

[0055] Further, such as Figure 6, Figure 7 , Figure 8 and Fig. 9 As shown, the side wall of the worm wheel 403 is meshed with a transmission gear 404, and the transmission gear 404 is located on the side of the mounting frame 401 close to the mounting plate 301. A first sliding groove 405 is provided on the side of the mounting frame 401 close to the transmission gear 404, and the mounting frame 401 is sleeved with the transmission gear 404 through the first sliding groove 405.

[0056] The mounting frame 401 is sleeved with the transmission gear 404 through the first sliding groove 405, so as to facilitate the sliding of the transmission gear 404. When the worm gear 403 is meshed with the transmission gear 404, the transmission gear 404 can be driven to rotate synchronously.

[0057] Further, such as Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the transmission gear 404 has extension shafts on both sides, and the extension shafts extend through the mounting frame 401 to its outside. The transmission gear 404 is sleeved with a second synchronous belt 407 through the extension shafts on both sides. The second synchronous belt 407 is located in the inner cavity of the mounting frame 401, and the other end of the second synchronous belt 407 is sleeved with a sub-gear 406, and the sub-gear 406 is meshed with the main gear 308.

[0058] An extension shaft is provided on the outer side of the secondary gear 406, and the secondary gear 406 is connected to the second synchronous belt 407 through the extension shaft. When the transmission gear 404 rotates, the second synchronous belt 407 provided on both sides thereof facilitates the secondary gear 406 to rotate synchronously, thereby facilitating the main gear 308 meshing therewith to rotate.

[0059] Further, such as Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, second slide grooves 410 are provided on both sides of the mounting frame 401 , and the mounting frame 401 is sleeved with the sub-gear 406 through the second slide grooves 410 .

[0060] The second sliding groove 410 is provided to facilitate the sliding of the secondary gear 406 and to limit its position.

[0061] Further, such as Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, inclined plates 408 are symmetrically installed on both sides of the mounting frame 401, and an electric push rod 411 is fixedly installed at the bottom of the inclined plate 408. One end of the inner side of the inclined plate 408 is fixedly connected to the transmission gear 404, and the other end of the inner side of the inclined plate 408 is sleeved with the extension shaft outside the sub-gear 406.

[0062] The electric push rod 411 is provided to facilitate the movement of the inclined plate 408 , thereby synchronously driving the transmission gear 404 and the sub-gear 406 to move through the inclined plate 408 .

[0063] Further, such as Figure 3 , Figure 4 and Figure 8 As shown, a wire hole 409 is formed through the top of the inclined plate 408, and a pull rope 5 is sleeved on the inclined plate 408 through the wire hole 409. One end of the pull rope 5 is fixedly connected to the top of the sliding base 1, and the other end of the pull rope 5 is fixedly connected to the outer side of the side plate 205 located at the top.

[0064] At this time, the pull rope 5 is in a taut state. When the pull rope 5 bends as the inclined plate 408 moves downward, the side plate 205 will be pulled synchronously by the pull rope 5 to move, thereby changing the angle of the roller 201.

[0065] The use process of the loading and unloading device for the vacuum coating machine provided by the present invention is as follows:

[0066] Preparation for loading: First, place the device in an appropriate position, then start the electric push rod 411, which drives the inclined plate 408 fixedly connected to its telescopic end to move downward, thereby driving the pull rope 5 to apply pressure, so that it moves downward with the inclined plate 408, and synchronously pulls the side plate 205, so that the entire unloading assembly 2 rotates around the connecting shaft 305 until it is rotated to a horizontal state. At this time, the telescopic end of the electric push rod 411 and the inclined plate 408 are moved to the lowest position, and the worm wheel 403 and the worm 304 are engaged, and then prepare for loading;

[0067] Material discharge: At this time, the driving motor 402 is started, and the driving motor 402 rotates through the second synchronous belt 407 and the worm gear 403 connected thereto, and the worm gear 403 drives the worm 304 connected thereto to rotate. While the worm 304 rotates, the synchronous wheel 303 installed on its top and the first synchronous belt 302 drive the roller 201 to rotate, thereby adjusting the position of each set of material discharge plates 202, so that it is convenient to discharge materials, and each set of material discharge plates 202 needs to pass through the inner side of the mounting plate 301 before discharging materials, and the outer surface of the material discharge plate 202 is cleaned through the mounting plate 301, and then the staff takes out the template 203 and magnetically absorbs it on the outer side of the material discharge plate 202 until a set of templates 203 are placed. At this time, other operations can also be performed on the template 203 through the central groove 204 opened on the material discharge plate 202;

[0068] Loading: Reverse the above steps and extend the electric push rod 411 to reset the entire unloading assembly 2. At this time, the template 203 is vertical and can be transported by the sliding base 1. The unloading plate 202 can be used for protection during the movement until the device moves to the loading position of the vacuum coating machine. At this time, repeat the above steps again to make the unloading assembly 2 horizontal, and slowly rotate the roller 201, so that the unloading plate 202 contacts the disc of the vacuum coating machine in turn. Since the disc of the vacuum coating machine also fixes the template by magnetic attraction, the electromagnet built in the unloading plate 202 is turned off when it contacts to complete the transfer of the template 203, thereby completing the loading operation of the template 203;

[0069] Unloading: Similarly, if unloading is required, the unloading plate 202 is contacted with the disc of the vacuum coating machine in turn, and the template 203 is transferred through magnetic opening and closing. After the transfer is completed, the unloading component 2 is reset and moved through the electric push rod 411 and the pull rope 5. After moving to the appropriate position, the worm gear 403 drives the transmission gear 404 meshing with it to rotate, and drives the sub-gear 406 through the transmission gear 404 and the second synchronous belt 407, and then cooperates with the sub-gear 406 and the main gear 308 and the gear rod 307 to drive the bevel gear 306 to rotate, thereby driving the roller 201 to rotate as described above. At this time, the unloading plate 202 is connected to the inner wall of the mounting plate 301 and continues to slide, thereby realizing auxiliary scraping and cleaning operations through the mounting plate 301.
