The automated material handling mechanisms and turnover carts on the production line are essential for loading and unloading the coating. The turnover carts corresponding to different process steps have different positions relative to the production line. On highly automated vacuum coating lines, when automated material handling mechanisms are used to handle product handling, the positioning of the turnover carts is crucial for loading and unloading the coating.

[0003] The turnover carts in existing production sites are usually free-moving, and a brake mechanism is set on the casters of the turnover cart to make the turnover cart stationary.

[0035] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0036] Example 1:

[0037] like Figure 1 —9, the utility model provides a material turnover mechanism, which can be applied to the automated auxiliary production line of a vacuum coating production line. The material turnover mechanism can be set in the loading and unloading processes of the vacuum coating production line, and the material turnover mechanism is set according to the automated material conveying mechanism on the vacuum coating production line. The material turnover mechanism includes a turnover conveyor 100 and a first positioning mechanism 200 for positioning the turnover conveyor 100. The first positioning mechanism 200 can be fixedly installed on the ground of the production site according to the loading and unloading positions of the vacuum coating production line. The turnover conveyor 100 is used to load and transport products to be coated or coated products; the first positioning mechanism 200 can be set according to the loading and unloading positions of the vacuum coating production line and the automated material conveying mechanism, and the turnover conveyor 100 is repeatedly positioned by the first positioning mechanism 200 to ensure that the turnover conveyor 100 can reach the same position, angle and posture each time the materials are loaded and unloaded, so that the automated material conveying mechanism on the production line can more accurately grasp and convey materials, reduce errors caused by inaccurate positioning, and help improve the turnover efficiency of materials, thereby improving the loading and unloading efficiency of the production line. For example, in the loading process, when the peripheral conveyor 100 loaded with the product to be coated moves to the first positioning mechanism 200, the peripheral conveyor 100 is fixed by the first positioning mechanism 200, and the surface of the product to be coated faces the vacuum coating production line, so that the automated material conveying mechanism can take the product to be coated from the peripheral conveyor 100 and convey it to the production line for processing; for another example, in the unloading process, the peripheral conveyor 100 can first be fixed in position, angle and posture relative to the vacuum coating production line by the first positioning mechanism 200, and the coated products on the production line are directly conveyed to the peripheral conveyor 100 by the automated material conveying mechanism, thereby completing the unloading of the finished product.

[0038] like Figure 1As shown in FIG6 , the transport vehicle 100 includes a base 110, a clamping mechanism mounted on the base 110, and a traveling mechanism for moving the base 110. The clamping mechanism is used to clamp the material 400, and the traveling mechanism can drive the base 110 to move the transport vehicle 100. A clearance space 101 communicating with the outside is defined between the bottom of the base 110 and the traveling mechanism. A positioning member 111 is provided at the bottom of the base 110, the bottom of which extends vertically downward and into the clearance space 101. The traveling mechanism is disposed at the bottom of the base 110, enabling the base 110 to be raised above the production floor, thereby forming a clearance space 101 between the base 110 and the traveling mechanism. The clearance space 101 allows the first positioning mechanism 200 to pass through. In this embodiment, the material 400 can be understood as the product to be coated or the product already coated during the vacuum coating process.

[0039] The first positioning mechanism 200 includes a fixed space 240 adapted to the positioning member 111. The positioning member 111 is clamped by the fixed space 240. The positioning member 111 can move synchronously with the peripheral transport tool 100 and move into the fixed space 240 in the first positioning mechanism 200, so that the first positioning mechanism 200 clamps the positioning member 111, thereby realizing that the first positioning mechanism 200 fixes the peripheral transport tool 100. The structure is simple and easy to produce and implement.

[0040] In this embodiment, the bottom of the positioning member 111 extends in a direction parallel to the height direction of the base 110. Figure 1 To prevent positioning member 111 from being too long and thus affecting the movement of the rotary transport vehicle 100, the height of positioning member 111 is preferably slightly smaller than the height of clearance space 101, which is the distance between the base 110 and the production site floor. Positioning member 111 has a simple structure and is easy to implement in production.

[0041] In some embodiments, the positioning member 111 is fixedly connected to the base 110, such as by welding the positioning member 111 to the base 110. In other embodiments, such as Figure 2 As shown, the positioning member 111 is detachably connected to the base 110 via a connecting member 114 . The connecting member 114 can be installed in the base 110 via fasteners such as screws and bolts to facilitate the disassembly, assembly, maintenance and replacement of the positioning member 111 .

[0042] In some embodiments, the left and right sides of the positioning member 111 extend along the length direction of the base 110, that is, the left and right sides of the positioning member 111 extend along the length direction of the base 110. Figure 1extends in the direction of the X-axis; in other embodiments, the left and right sides of the positioning member 111 extend along the width direction of the base 110, i.e., the left and right sides of the positioning member 111 extend along the Y-axis direction of the base 110. Figure 1 extends in the direction of the Y-axis. For example, the positioning member 111 can be provided as a long strip-shaped member, the left and right sides of which extend along the length direction or the width direction of the base 110, and the extending direction of the left and right sides of the positioning member 111 can be understood as the length direction of the positioning member 111, and the first positioning mechanism 200 is provided according to the length direction of the positioning member 111.

[0043] In the present embodiment, as shown in Figure 7 The first positioning mechanism 200 includes a mounting seat 210, a first positioning assembly 221 and a second positioning assembly 222 oppositely arranged in the mounting seat 210, a fixed space 240 is formed between the first positioning assembly 221 and the second positioning assembly 222, and each of the first positioning assembly 221 and the second positioning assembly 222 is provided with a second conveying surface capable of driving the positioning member 111 to move in the fixed space 240, the two second conveying surfaces are oppositely arranged and spaced apart to form the fixed space 240; the first positioning assembly 221 and the second positioning assembly 222 can be installed in the production site through the mounting seat 210, the two second conveying surfaces extend along the length direction of the positioning member 111, the positioning member 111 can be moved to between the first positioning assembly 221 and the second positioning assembly 222 and into the fixed space 240 through the walking mechanism, the two side walls of the positioning member 111 are in contact with the two second conveying surfaces respectively, the positioning member 111 is driven to move into the fixed space 240 through the two second conveying surfaces, and the positioning member 111 is fixed by the first positioning assembly 221 and the second positioning assembly 222, so that the first positioning mechanism 200 fixes the turnover carrier 100; the turnover carrier 100 can be separated from the first positioning mechanism 200 by moving the positioning member 111 in the opposite direction relative to the first positioning assembly 221 and the second positioning assembly 222, at this time, the turnover carrier 100 can move freely in the production site. By arranging the two second conveying surfaces on both sides of the fixed space 240, the movement efficiency of the positioning member 111 in the fixed space 240 can be improved, thereby improving the positioning efficiency of the first positioning mechanism 200 on the turnover carrier 100, and further improving the turnover efficiency of the material 400.

[0044] It should be noted that the first positioning assembly 221 and the second positioning assembly 222 can be provided as conveying devices capable of driving the positioning member 111 to move, such as belt conveying devices, roller conveying devices, etc. In some embodiments, as shown in Figure 7As shown, the first positioning assembly 221 and the second positioning assembly 222 each include a plurality of second conveying components 2201, each of which is arranged in the mounting seat 210 in an axially rotatable manner. The mounting seat 210 oppositely has a first mounting portion 211 and a second mounting portion 212, the first mounting portion 211 is used for mounting the first positioning assembly 221, and the second mounting portion 212 is used for mounting the second positioning assembly 222.

The plurality of second conveying components 2201 in the first positioning assembly 221 are uniformly arranged along the extension direction of the first mounting portion 211. The plurality of second conveying components 2201 in the second positioning assembly 222 are uniformly arranged along the extension direction of the second mounting portion 212, i.e., each of the second conveying components 2201 is arranged in the first mounting portion 211 and the second mounting portion 212 in an axially rotatable manner. The two second conveying surfaces located on both sides of the fixed space 240 are formed by the axial rotation of each of the second conveying components 2201 in the first positioning assembly 221 and the second positioning assembly 222. The positioning member 111 is driven to move in the fixed space 240 by the two second conveying surfaces. In actual application, the positioning member 111 can move relative to the first positioning assembly 221 and the second positioning assembly 222 and in and out of the fixed space 240 through the walking mechanism. At the same time, each of the second conveying components 2201 is axially rotated under the friction of the positioning member 111, which further drives the positioning member 111 to move into the fixed space 240. The arrangement of each of the second conveying components 2201 is conducive to improving the efficiency of the movement of the positioning member 111 relative to the first positioning assembly 221 and the second positioning assembly 222, thereby improving the positioning efficiency of the turnover carrier 100 and further improving the turnover efficiency of the material 400. Optionally, each of the second conveying components 2201 can be a roller.

The third limiting portion 260 is arranged at the end of the movement path of the positioning member 111 in the fixed space 240. The positioning member 111 stops by contacting the third limiting portion 260. The movement distance of the positioning member 111 in the fixed space 240 is limited by the third limiting portion 260, so as to avoid the positioning member 111 from leaving the fixed space 240, thereby improving the positioning efficiency of the turnover carrier 100 in the first positioning mechanism 200.

[0046] In this embodiment, the material turnover mechanism further includes a guide structure for guiding the positioning member 111 to enter the fixed space 240 , and the guide structure is provided in the positioning member 111 and / or the first positioning mechanism 200 .

The first introduction component 251 and the second introduction component 252 are both provided with a third conveying surface capable of guiding the positioning member 111 to move toward the fixed space 240. The two third conveying surfaces are arranged opposite to each other, and the space between the two third conveying surfaces is large. The distance gradually increases in the direction away from the fixed space 240; the mounting seat 210 is provided with a third mounting portion 213 and a fourth mounting portion 214 relative to each other, the third mounting portion 213 is used to install the first introduction component 251, and the fourth mounting portion 214 is used to install the second introduction component 252, the third mounting portion 213 and the fourth mounting portion 214 extend in the direction away from the fixed space 240, and the third mounting portion 213 and the second conveying surface provided in the first positioning component 221 have a third preset angle between them, and the fourth mounting portion 214 and the second conveying surface provided in the second positioning component 222 have a fourth preset angle between them, that is, Figure 8 As shown, the third mounting portion 213 and the fourth mounting portion 214 are relative to the central axis therebetween (i.e. Figure 8The dotted line in the figure, which is parallel to the second conveying surface in the first positioning component 221 and the second conveying surface in the second positioning component 222) has a third preset angle and a fourth preset angle, the first introduction component 251 and the second introduction component 252 are provided with the third conveying surface on the opposite side, and an introduction space 2501 capable of guiding the positioning member 111 to move into the fixed space 240 is formed between the two third conveying surfaces, and the introduction space 2501 is provided at the entrance of the fixed space 240, and the end of the introduction space 2501 is provided.

The positioning member 111 is driven to move into the fixed space 240 more quickly by the two third conveying surfaces, thereby improving the positioning efficiency of the rotational transport vehicle 100 and further improving the turnover efficiency of the material 400. The first introduction component 251 and the second introduction component 252 can be configured as a conveying device capable of driving the positioning member 111 to move, such as a belt conveyor, a roller conveyor, etc. In some embodiments, the first introduction component 251 and the second introduction component 252 both include a plurality of third conveying components 2502.

Optionally, the first conveying member 152 can be a roller.

[0054] In other embodiments, Figure 1 As shown, at least two support assemblies 150 are provided, and the support assemblies 150 are spaced apart along the moving direction of the material 400 to help maintain the balance of the material 400. In addition, depending on the total length of the material 400, two to four support assemblies 150 can be provided, with one support assembly 150 positioned on each of the left and right sides of the material 400, and at least one support assembly 150 positioned near the middle of the material 400.

[0055] In this embodiment, if Figure 1 and Figure 5As shown, the clamping mechanism also includes at least one second clamp assembly 122 arranged between the first clamp assembly 121 and the support mechanism, the second clamp assembly 122 is located on one side of the material clamping space, the second clamp assembly 122 includes a second clamping jaw 1222 slidably connected to the first mounting bracket 140, and the second clamping jaw 1222 moves horizontally relative to the first mounting bracket 140 to approach or move away from the material clamping space; the material clamping space is formed by the first clamp assembly 121, the second clamp assembly 122 and the support mechanism to enhance the fixing effect of the clamping mechanism on the material 400 and protect the safety of the material 400. The second clamp assembly 122 can be arranged on the left or right side of the material clamping space, and the material 400 can enter and exit the material clamping space through the side opposite to the second clamp assembly 122. The second clamping jaw 1222 is provided with a contact surface 1201 on the side facing the material clamping space that can contact the outer edge of the material 400. The second telescopic drive device 1221 drives the second clamping jaw 1222 to move horizontally toward or away from the material 400, so as to realize the action of the second clamping jaw 1222 fixing the material 400 and releasing the material 400.

[0056] In some embodiments, the second clamp assembly 122 further includes a second telescopic drive device 1221 connected to the first mounting bracket 140, and the second clamping jaw 1222 is connected to the second telescopic drive device 1221. The second telescopic drive device 1221 can drive the second clamping jaw 1222 to move in the horizontal direction. Optionally, the second telescopic drive device 1221 can be a cylinder drive device. It should be noted that the second clamping jaw 1222 moves in the horizontal direction through the second telescopic drive device 1221, that is, the second clamping jaw 1222 moves in the horizontal direction. Figure 1 Move in the direction of the X axis.

[0057] In this embodiment, if Figure 5As shown, the second clamping jaw 1222 is provided with a rotating connecting portion 1224, the second clamping jaw 1222 is driven to rotate relative to the first mounting bracket 140 through the rotating connecting portion 1224; a limiting structure is arranged between the second clamping jaw 1222 and the rotating connecting portion 1224, and the limiting structure is used to limit the rotation of the second clamping jaw 1222 relative to the first mounting bracket 140. Specifically, the second clamping jaw 1222 is connected with the second telescopic driving device 1221 through a connecting bracket 1223, a rotating connecting portion 1224 is arranged between the second clamping jaw 1222 and the connecting bracket 1223, the second clamping jaw 1222 can rotate relative to the connecting bracket 1223 through the rotating connecting portion 1224, and the second clamping jaw 1222 can be flipped and swung relative to the connecting bracket 1223 around the rotating connecting portion 1224 under the action of an external force, so that the second clamping jaw 1222 can be flipped to approach or move away from the material 400; when the contact surface 1201 of the second clamping jaw 1222 is flipped to be parallel to the second telescopic driving device 1221, that is, the contact surface 1201 of the second clamping jaw 1222 is parallel to the material 400 and is spaced apart from the material 400, at this time, the material 400 can enter and exit the material clamping space through the second clamping jaw 1222; when the contact surface 1201 of the second clamping jaw 1222 is flipped to be perpendicular to the second telescopic driving device 1221, that is, the contact surface 1201 of the second clamping jaw 1222 is perpendicular to the material 400 and is in contact with the material 400, at this time, the material 400 is fixed by the second clamp assembly 122; in this way, the material 400 can enter and exit the material clamping space through the left and right sides of the transfer carrier 100, so as to facilitate the production personnel to load and unload the material 400. Optionally, the rotating connecting portion 1224 can be provided as a hinged portion or an electric rotating device. Figure 5As shown, the limiting structure is arranged as a positioning pin 1225 connected between the second clamping jaw 1222 and the connecting bracket 1223, and the positioning pin 1225 is used to limit the rotation of the second clamping jaw 1222 relative to the connecting bracket 1223. The second clamping jaw 1222 and the connecting bracket 1223 are respectively provided with a first through hole and a second through hole for accommodating the positioning pin 1225. When the first through hole and the second through hole are aligned during assembly, the positioning pin 1225 is simultaneously penetrated through the first through hole and the second through hole, thereby fixing the second clamping jaw 1222 and the connecting bracket 1223, so as to limit the overturning of the second clamping jaw 1222, facilitate the contact between the second clamping jaw 1222 and the material 400, and enhance the fixing effect of the second clamping jaw 1222 on the material 400. When the positioning pin 1225 is withdrawn from the first through hole and placed in the second through hole, the positioning pin 1225 cancels the fixation of the second clamping jaw 1222, so that the second clamping jaw 1222 can overturn relative to the connecting bracket 1223, and meanwhile, the positioning pin 1225 is placed in the connecting bracket 1223 through the second through hole, thereby avoiding the loss of the positioning pin 1225. Preferably, the first through hole and the second through hole are arranged as internally threaded holes, and the outer wall of the positioning pin 1225 is provided with an externally threaded part engaged with the internally threaded holes. In other embodiments, the upper and lower sides of the second clamping jaw 1222 and the connecting bracket 1223 are both provided with the positioning pin 1225.

[0058] In other embodiments, as shown in Figure 1 As shown, two second clamping assemblies 122 can be arranged, and the two second clamping assemblies 122 are oppositely arranged on the left and right sides of the material clamping space. The two second clamping jaws 1222 are both connected with the second telescopic driving device 1221 through the connecting bracket 1223, and the positioning pin 1225 is arranged between each second clamping jaw 1222 and the connecting bracket 1223. By arranging the second clamping assemblies 122 on the left and right sides of the material clamping space, the fixing effect of the clamping mechanism on the material 400 is further enhanced.

[0059] It should be noted that all products that can be clamped and fixed by the clamping mechanism can be transported by the turnover carrier 100 of the present application, and are not limited to the above-mentioned vacuum-coated products.

[0060] In the present embodiment, as shown in Figure 1 As shown, the first mounting bracket 140 is provided with a handle 160 on one side. The handle 160 is arranged on the side of the first mounting bracket 140 away from the clamping mechanism, which is conducive to the pushing of the turnover carrier 100 by the production personnel. Further, the left and right sides of the first mounting bracket 140 can also be provided with handles 160.

[0061] Embodiment two:

[0062] The difference between this embodiment two and the above-mentioned embodiment one is that the turnover carrier 100 further comprises an electric control mechanism electrically connected with the walking mechanism, the electric control mechanism drives the walking mechanism to run, and the walking mechanism drives the base 110 to move. The production personnel can drive the electric control mechanism through wireless, remote control, PLC programming and other control methods, and the electric control mechanism drives the walking mechanism to run, thereby realizing the automatic walking of the turnover carrier 100. In addition, the electric control mechanism can also be electrically connected with each telescopic driving device, and the production personnel can adjust the running state of each telescopic driving device through the electric control mechanism.

[0063] In other embodiments, the turnover carrier 100 can be provided with both the handle 160 and the electric control mechanism, so as to facilitate the production personnel to flexibly select manual driving or electric driving of the turnover carrier 100, and make the turnover carrier 100 suitable for production sites with complex environment.

[0064] Embodiment three:

[0065] This embodiment three can be further improved on the basis of the above-mentioned embodiments, such as Figure 10 As shown in FIG. 13, the material turnover mechanism further comprises a second positioning mechanism 300 arranged on one side of the first positioning mechanism 200, the second positioning mechanism 300 comprises a third mounting bracket 310, an extension bracket 320 arranged on one side of the third mounting bracket 310, and at least one third clamp assembly 330 connected with the extension bracket 320, the third clamp assembly 330 is located above the first positioning mechanism 200, the third clamp assembly 330 comprises a third clamping jaw 332 slidingly connected on the extension bracket 320, the third clamping jaw 332 moves in the vertical direction relative to the extension bracket 320 to approach or move away from the turnover carrier 100, and a second clamping groove 3321 is arranged in the third clamping jaw 332 and faces the first positioning mechanism 200. The third mounting bracket 310 is vertically arranged in the production site and located on one side of the first positioning mechanism 200, the extension bracket 320 is arranged close to the top of the third mounting bracket 310, the extension bracket 320 extends to one side and is located above the first positioning mechanism 200, and the extension bracket 320 is arranged with the third clamp assembly 330 opposite to the first positioning mechanism 200. When the third clamp assembly 330 operates, the third clamping jaw 332 can clamp the material 400 through the second clamping groove 3321, and the third clamping jaw 332 moves in the vertical direction to approach or move away from the material 400, so as to realize the action of clamping and fixing the material 400 and releasing the material 400.

[0066] In some embodiments, the third clamp assembly 330 further comprises a third telescopic driving device 331 connected with the extension support 320, the third clamping jaw 332 is connected with the third telescopic driving device 331, the third telescopic driving device 331 can drive the third clamping jaw 332 to move along the vertical direction, that is, the third clamping jaw 332 moves along the direction in the Z-axis. Figure 1 The third telescopic driving device 331 drives the third clamping jaw 332 to move along the vertical direction to approach or move away from the material 400, so as to realize the action of clamping and fixing the material 400 and releasing the material 400 by the third clamping jaw 332.

[0067] For example, when loading, first, the turnover carrier 100 loaded with the material 400 is positioned by the first positioning mechanism 200, the third clamp assembly 330 in the second positioning mechanism 300 moves downward, and the material 400 is clamped by the third clamp assembly 300 and the supporting mechanism in the turnover carrier 100. At this time, the clamping mechanism in the turnover carrier 100 can cancel the clamping of the material, then the material 400 is clamped by the automatic material conveying mechanism, and the material is supported by the supporting mechanism. At this time, the third clamp assembly 330 releases the material and moves upward to reset, and then the material 400 is conveyed to the vacuum coating production line by the automatic material conveying mechanism. It should be noted that when the automatic material conveying mechanism clamps the material, the turnover carrier 100 can exit the first positioning mechanism 200 and repeat the loading step of the material 400. For example, when unloading, the empty turnover carrier 100 is positioned by the first positioning mechanism 200, the product after coating is placed on the supporting mechanism of the turnover carrier 100 by the automatic material conveying mechanism, the product is fixed by the automatic material conveying mechanism and the supporting mechanism, then the third clamp assembly 330 moves downward and clamps the product together with the supporting mechanism, the automatic material conveying mechanism cancels the clamping of the product, and the automatic material conveying mechanism releases the product and returns to the vacuum coating production line. Then, the product is clamped by the clamping mechanism of the turnover carrier 100, and the product is supported by the supporting mechanism, then the third clamp assembly 330 releases the product and moves upward to reset, and the turnover carrier 100 can move to the product storage area with the product after coating.

[0068] During the loading and unloading process, the third clamp assembly 330 assists in transferring the material between the automatic material conveying mechanism and the turnover carrier 100, and the supporting mechanism supports the material, which is beneficial to protect the material and prevent the material from falling, especially for some large and heavy workpieces. Moreover, when the automatic material conveying mechanism clamps the material during loading, the turnover carrier can be removed and the next step can be performed, which is beneficial to improve the repeated use of the turnover carrier and improve the turnover efficiency of the turnover carrier 100.

[0069] In other embodiments, two third clamp assemblies 330 are provided to help the material 400 maintain balance and enhance the fixing effect of the third clamp assemblies 330 on the material 400.

[0070] It should be noted that if Figure 12 As shown, when the peripheral conveyor 100 is fixed in the first positioning mechanism 200, in order to achieve the accurate gripping of the material 400 by the third clamping jaw 332, the second clamping groove 3321, the first clamping groove 1200 and the first conveying surface 1501 are in the same vertical direction (i.e. Figure 12 in the direction indicated by the dotted line).

[0071] In some embodiments, as Figure 11 and Figure 12 As shown, the third clamping jaw 332 is further provided with third auxiliary positioning members 3322 located on both sides of the second clamping groove 3321. A plurality of third auxiliary positioning members 3322 may be provided and evenly spaced within the third clamping jaw 332. Each third auxiliary positioning member 3322 extends into the second clamping groove 3321. The third auxiliary positioning members 3322 contact the material 400 to further secure the material 400, thereby enhancing the securing effect of the third clamping jaw 332 on the material 400. In other embodiments, the portion of the third auxiliary positioning member 3322 that contacts the material 400 may be made of a flexible material. When the material 400 is a glass product, the flexible material not only clamps the material 400 but also protects the material 400 from scratches.

[0072] The above examples are merely used to further illustrate the technical content of the present invention for easier understanding by the reader.
