Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0033] The transfer device and transfer system provided in the embodiments of this application will now be described.

[0034] like Figure 1-6 As shown, this utility model provides a substrate glass transport trolley maintenance and transfer device, including: a frame 100, a lifting mechanism 200, and a trolley transfer mechanism 300; the lifting mechanism 200 includes a lifting drive assembly 210 disposed on the frame 100 and a lifting platform 220 disposed on the lifting drive assembly 210; the trolley transfer mechanism 300 is disposed on the lifting platform 220, with one end of the trolley transfer mechanism 300 aligned with the production line. When the transport trolley malfunctions, the transport trolley is pushed from the production line onto the trolley transfer mechanism 300 without affecting the operation of subsequent trolleys. Then, the lifting drive assembly 210 performs an action to lift the trolley transfer mechanism 300 disposed on the lifting platform 220, so that the transport trolley reaches a designated height for maintenance. After the malfunction is resolved, it is moved back into the production line, avoiding long-term downtime for maintenance, improving production efficiency, reducing economic losses, and allowing the transport trolley to be transferred more quickly between the production line and the maintenance station, shortening the time and facilitating regular maintenance of the transport trolley.

[0035] In one embodiment, the lifting drive assembly 210 includes: a drive motor 211, a rotary-linear motion converter 212 connected to the output end of the drive motor 211, and a guide assembly 213 arranged vertically on the frame 100. The output power of the drive motor 211 is transmitted through the rotary-linear motion converter 212 to drive the lifting platform 220 to move along the guide assembly 213. Specifically, the frame 100 is a three-dimensional frame structure with side panels in some locations to protect the equipment inside and prevent personnel from accidentally touching the operating equipment and causing accidental injury. The drive motor 211 is a servo motor, stepper motor, or geared motor, which is fixed to the inner bottom of the frame 100 by a dedicated base and bolts. The rotary-linear motion converter 212 is connected to the inner top and inner bottom of the frame 100 by bolts or welding, converting the rotational mechanical energy of the drive motor 211 into vertical linear motion to drive the lifting platform 220 to move along the guide assembly 213, thereby raising or lowering the trolley transfer mechanism 300. The guide assembly 213 is connected to the frame 100 by bolts or welding, which provides support and stable guidance for the transport trolley.

[0036] In one embodiment, such as Figure 3 and Figure 4 As shown, the rotary-linear motion converter 212 includes a drive gear 2121 mounted on the drive motor 211, a transmission chain 2122 meshing with the drive gear 2121, and a driven gear 2123 mounted on the upper part of the frame 100. The transmission chain 2122 meshes with the driven gear 2123, and the lifting platform 220 is fixed to the transmission chain 2122 via a connecting plate 320. Specifically, the drive gear 2121 is coaxially fixed with the output shaft of the drive motor 211, and the driven gear 2123 is fixed to the inner top of the frame 100 via a dedicated base and bolts or welding, and is located vertically above the drive gear 2121. The drive motor 211 drives the gear to rotate, and the transmission chain 2122 drives the lifting platform 220 to rise or fall linearly. The transmission chain 2122 is easier to adjust in length via chain links to accommodate the drive gear 2121 and the driven gear 2123 with a certain height difference, thus offering greater flexibility.

[0037] In one embodiment, such as Figure 5As shown, the rotary-linear motion converter 212 includes a lead screw slide 2124. The output shaft of the drive motor 211 is connected to the lead screw slide 2124. The lead screw slide 2124 is mounted on the frame 100 and parallel to the guide assembly 213. The slide 2125 of the lead screw slide 2124 is connected to the lifting platform 220. Specifically, both ends of the lead screw slide 2124 are fixed to the bottom and top of the frame 100 by bolts or welding. The slide 2125 is fixed to the lifting platform 220 by bolts or welding. The drive motor 211 drives the lead screw in the lead screw slide 2124 to rotate, causing the slide 2125 to move linearly up and down, while simultaneously causing the lifting platform 220 to move linearly up and down along the guide assembly 213. The lead screw slide 2124 itself has high rigidity and also provides support and guidance for the lifting platform 220.

[0038] In some embodiments, the rotary-linear motion converter 212 includes a drive gear 2121 mounted on a drive motor 211, a transmission chain 2122 meshing with the drive gear 2121, a driven gear 2123 mounted on the upper part of the frame 100, and a lead screw slide 2124. The drive gear 2121 is coaxially fixed on the output shaft of the drive motor 211, and the end of the output shaft is connected to the lead screw slide 2124 via a coupling, so that one drive motor 211 can synchronously drive two rotary-linear motion converters 212. It should be noted that the number of teeth of the lead screw of the lead screw slide 2124 and the drive gear 2121 must match.

[0039] Of course, in some embodiments, the number of drive motors 211 is two, which drive the drive gear 2121 and the lead screw slide 2124 respectively.

[0040] In one embodiment, the drive motor 211 has two output shafts, each equipped with a drive gear 2121. The rotary-linear motion converter 212 includes two drive gears 2121 connected to the two output shafts of the drive motor 211, two transmission chains 2122 meshing with the two drive gears 2121, and two driven gears 2123 mounted on the upper part of the frame 100. The two transmission chains 2122 mesh with the two driven gears 2123. Thus, the two transmission chains 2122 jointly drive the lifting platform 220, making the lifting platform 220 more balanced and facilitating more stable lifting or lowering of the transport trolley.

[0041] In one embodiment, the guide assembly 213 includes linear guide posts 2131 mounted on a bracket and linear bearings 2132 sleeved on the guide posts. The lifting platform 220 is fixedly connected to the linear bearings 2132. Specifically, the number of linear guide posts 2131 is two, three, or more, and each guide post is sleeved with one or two or more linear bearings 2132 to ensure sufficient support and guiding stability for the lifting platform 220.

[0042] In one embodiment, the guide assembly 213 includes a linear guide pair mounted on a bracket, and the lifting platform 220 is fixedly connected to a slider of the linear guide pair. Specifically, the number of linear guide pairs is two, three, or more, to ensure sufficient support and guiding stability for the lifting platform 220.

[0043] In some embodiments, the linear guide pair and the linear guide post 2131 / linear bearing 2132 can be used in combination.

[0044] In one embodiment, the lifting platform 220 includes: a support plate 221, a mounting plate 222 disposed on the support plate 221, and a plurality of pads 223 disposed on the top of the support plate 221. The trolley transfer mechanism 300 is disposed on the plurality of pads 223. Specifically, the support plate 221 is a flat plate, the length and width of which are not less than the length and width of the trolley transfer mechanism 300. The mounting plate 222 has a right-angle contact surface that fits against the bottom and side of the support plate 221. One, two, three or more mounting plates 222 are fixedly connected to the support plate 221. The side of the mounting plate 222 facing away from the support plate 221 is connected to the slider of the linear shaft and / or the linear guide pair. The plurality of pads 223 are equivalent to a base for supporting and connecting the trolley transfer mechanism 300.

[0045] In one embodiment, a support column 110 is provided on the frame 100, and the support column 110 is arranged parallel to the guide assembly 213. The support column 110 is equipped with a plurality of position sensors 120. Specifically, a position sensor 120 is arranged at intervals from top to bottom on the support column 110 to sense and determine the height of the transport trolley. The position sensor 120 can be a photoelectric encoder, a laser rangefinder, or a photoelectric switch.

[0046] In one embodiment, such as Figure 4 As shown, a limit plate 130 is provided on the support column 110 near its bottom end, and the limit plate 130 extends laterally to the bottom of the lifting platform 220. The limit plate 130 is used to prevent the lifting platform 220 from continuing to move downward, so as to avoid collision with the drive motor 211 and other equipment, which could cause damage.

[0047] In one embodiment, a buffer pad 131 is provided on the top of the limiting plate 130 to buffer the impact force with the lifting platform 220 and reduce the probability of equipment damage. The buffer pad 131 is made of rubber or other materials.

[0048] In one embodiment, such as Figure 6 As shown, the trolley transfer mechanism 300 includes two parallel side plates 310, a connecting plate 320 connecting the two side plates 310, multiple rollers 330 rotatably mounted between the two connecting plates 320, and a second drive motor 340 mounted on one side of one of the side plates 310. The multiple rollers 330 are connected by transmission, and the second drive motor 340 drives the rollers to rotate, thereby moving the trolley to a designated position. Specifically, the two sides are used to guide the transport trolley. The second drive motor 340, through transmission gears 360 and chains 370 mounted on the rollers 330, causes all rollers 330 to rotate synchronously, so as to easily move the transport trolley to a designated position on the trolley transfer mechanism 300, such as the middle.

[0049] It should be noted that the frame 100 has an opening 101 for aligning with the trolley transfer mechanism 300, and an inspection port located on top.

[0050] In one embodiment, guide strips 380 are fixedly connected to the inner sides of both side plates 310 to prevent the transport trolley from directly colliding with the side plates 310 and causing damage. The guide strips 380 are made of rubber or other materials.

[0051] In one embodiment, the bottom of the frame 100 is provided with multiple support legs 140 for adjusting the balance of the frame 100 so that the lifting platform 220 can move vertically as much as possible.

[0052] In some embodiments, the bottom of the frame 100 is also provided with a plurality of casters, which may be swivel casters or casters, or a combination of swivel casters and casters.

[0053] In one embodiment, the trolley transfer mechanism 300 further includes two blocking cylinders 350 respectively disposed at both ends. When the transport trolley is transferred onto the trolley transfer mechanism 300, the two blocking cylinders 350 rise to block the front and rear of the transport trolley to prevent accidental slippage; the two blocking cylinders 350 descend to allow the transport trolley to move into or out of the trolley transfer mechanism 300.
