[0062] The following specific embodiments will further illustrate this application in conjunction with the above-described accompanying drawings. Detailed Implementation

[0063] The following specific embodiments are exemplary and not limiting, and are intended to provide a basic understanding of this application, and are not intended to identify key or decisive elements of this application or limit the scope of protection. As long as there is no structural conflict, the technical features mentioned in the various embodiments can be combined in any manner.

[0064] When a component is considered to be "located" on another component, it can be directly on the other component or may also be interspersed with other components. When a component is considered to be "connected" to another component, it can be directly connected to the other component or may also be interspersed with other components.

[0065] It is understandable that the term "perpendicular" is used to describe an ideal state between two components. In actual production or use, two components can exist in a state that is approximately perpendicular or equal to each other. For example, combined with numerical description, perpendicularity can refer to the angle between two straight lines within the range of 90° ± 10°, the dihedral angle between two planes within the range of 90° ± 10°, or the angle between a straight line and a plane within the range of 90° ± 10°. The two components described as "perpendicular" do not have to be absolutely straight lines or planes; they can be approximately straight lines or planes. From a macroscopic perspective, if the overall direction of extension is a straight line or plane, the component can be considered a "straight line" or "plane".

[0066] Unless otherwise defined, the term "multiple" in this document, when used to describe the number of components, specifically means that the component is two or more.

[0067] The following describes some embodiments of this application in detail with reference to the accompanying drawings.

[0068] Please see Figures 1 to 5 This application provides a material replacement device 100 for replacing consumables 201 on a preheating fixture 200. The preheating fixture 200 has a recess 202 and a first protrusion 203 disposed in the recess 202. The consumables 201 are disposed in the recess 202 and fitted onto the first protrusion 203.

[0069] In some embodiments, the preheating fixture 200 is used to preheat the glass, and the temperature at the location of the consumable 201 is higher, which facilitates the hot bending of the glass. Optionally, the glass is the glass used in electronic devices such as mobile phones and tablets. Optionally, the consumable 201 is a ring-shaped consumable part.

[0070] In some embodiments, the material changing device 100 includes a base 10, a push plate 20, and a pushing assembly 30. The base 10 is provided with a positioning block 11 and a second protrusion 12. The positioning block 11 is used to position the preheating fixture 200 so that the first protrusion 203 is opposite to the second protrusion 12. The consumable 201 used on the first protrusion 203 can fall under the action of gravity and be fitted onto the second protrusion 12.

[0071] Specifically, such as Figure 6 As shown, the consumable 201 is fixed to the preheating fixture 200 by fastener 101. When the consumable is replaced, after the preheating fixture 200 is positioned by the positioning block 11, the first protrusion 203 and the second protrusion 12 come into contact. In the thickness direction of the preheating fixture 200, the projection of the first protrusion 203 and the projection of the second protrusion 12 overlap. Then the fastener 101 is loosened, so that the consumable 201 used on the first protrusion 203 falls under the action of gravity and is fitted onto the second protrusion 12.

[0072] A push plate 20 is connected to the base 10 and is disposed on at least a portion of the periphery of the second protrusion 12. A push assembly 30 is connected to the push plate 20 and is used to lift the push plate 20, separating the used consumable 201 from the second protrusion 12 so that a new consumable 201 can be placed on the second protrusion 12. After the new consumable 201 is placed on the second protrusion 12, the push assembly 30 is used to lift the push plate 20 again, pushing the new consumable 201 into the recess 202 and fitting it onto the first protrusion 203.

[0073] Specifically, such as Figure 7 and Figure 8As shown, after the used consumable 201 falls under the action of gravity and is fitted onto the second protrusion 12, the preheating fixture 200 is moved first to facilitate the pushing component 30 to drive the push plate 20 to rise, separating the used consumable 201 from the second protrusion 12. After the new consumable 201 is placed on the second protrusion 12, the position of the preheating fixture 200 is repositioned by the positioning block 11. Then, the pushing component 30 drives the push plate 20 to rise, pushing the new consumable 201 into the recess 202 and fitting it onto the first protrusion 203, thus completing the replacement of the consumable 201.

[0074] This application utilizes the cooperation between the base 10, the push plate 20, and the push assembly 30 to replace the consumable 201, reducing the time spent waiting for the preheated fixture 200 to cool down and reheat, thereby improving production efficiency.

[0075] Please see Figure 1 , Figure 2 and Figure 6 In some embodiments, the positioning block 11 includes a first positioning block 111, the first positioning block 111 and the second protrusion 12 are arranged along the first direction X, and the preheating fixture 200 has a first sidewall 210. When the preheating fixture 200 is placed on the base 10, the first positioning block 111 contacts and connects to the first sidewall 210 to position the preheating fixture 200 along the first direction X.

[0076] The positioning block 11 includes a second positioning block 112. The second positioning block 112 and the second protrusion 12 are arranged along the second direction Y. The preheating fixture 200 has a second sidewall 220, and the first sidewall 210 is connected to the second sidewall 220. When the preheating fixture 200 is placed on the base 10, the second positioning block 112 contacts and connects to the second sidewall 220, positioning the preheating fixture 200 along the second direction Y. The first direction X is perpendicular to the second direction Y, which facilitates the alignment of the first protrusion 203 with the second protrusion 12, making it easier for the consumable 201 used on the first protrusion 203 to fall under gravity and be fitted onto the second protrusion 12.

[0077] In some embodiments, the positioning block 11 includes a third positioning block 113. The first positioning block 111 and the third positioning block 113 are arranged along the first direction X. The preheating fixture 200 has a third sidewall 230. A second sidewall 220 is connected to the third sidewall 230. The first sidewall 210 is opposite to the third sidewall 230. When the preheating fixture 200 is placed on the base 10, the third positioning block 113 contacts and connects to the third sidewall 230, reducing the movement of the preheating fixture 200 in the first direction X. This further facilitates the alignment of the first protrusion 203 with the second protrusion 12, making it easier for the consumable 201 used on the first protrusion 203 to fall under gravity and be fitted onto the second protrusion 12.

[0078] In some embodiments, the first positioning block 111 is provided with a first step portion 1111, the second positioning block 112 is provided with a second step portion 1121, and the third positioning block 113 is provided with a third step portion 1131, which further facilitates positioning the preheating fixture 200.

[0079] Please see Figure 2 , Figure 3 , Figure 7 and Figure 8 In some embodiments, the push plate 20 includes a main body 21 and a connecting part 22. The main body 21 can be sleeved on the outside of the second protrusion 12. The connecting part 22 connects to the main body 21. The base 10 has an opening 13. The connecting part 22 passes through the opening 13 and connects to the push assembly 30. The push assembly 30 moves along the third direction Z, causing the connecting part 22 to move within the opening 13 and causing the main body 21 to move, so that the main body 21 pushes the consumable 201 mounted on the second protrusion 12. The first direction X, the second direction Y, and the third direction Z are all perpendicular to each other.

[0080] In some embodiments, the push plate 20 includes two connecting portions 22 arranged along the second direction Y, each connecting portion 22 passing through the opening 13 and connected to a main body portion 21, so that the main body portion 21 can push the consumable 201 mounted on the second protrusion 12.

[0081] In some embodiments, the main body 21 is circumferentially disposed on the second protrusion 12, and two connecting portions 22 are arranged along the second direction Y and connected to the annular main body 21, thereby increasing the bearing area of ​​the main body 21 and the consumable 201, and further facilitating the main body 21 to push the consumable 201 mounted on the second protrusion 12.

[0082] Optionally, along the third direction Z, the projection of the consumable 201 overlaps with the projection of the main body 21, or along the third direction Z, the projection of the consumable 201 is located within the projection of the main body 21.

[0083] Please see Figure 2 and Figure 3 In some embodiments, the pushing assembly 30 includes a fixing member 31, a push rod 32, and a push handle 33. The fixing member 31 is fixedly connected to the side of the base 10 opposite to the second protrusion 12. The push rod 32 is movably disposed within the fixing member 31. One end of the push rod 32 is connected to the push plate 20, and the other end is connected to the push handle 33. The push handle 33 is slidably disposed relative to the fixing member 31.

[0084] Specifically, by sliding the push handle 33 relative to the fixing member 31 along the third direction Z, the push handle 33 drives the push rod 32 to rise, the push rod 32 drives the push plate 20 to rise, and thus the main body 21 of the push plate 20 pushes the consumable 201 mounted on the second protrusion 12.

[0085] In some embodiments, the fixing member 31 is provided with a receiving cavity 311 and a slide 312 communicating with the receiving cavity 311. The connecting part 22 is at least partially provided in the receiving cavity 311. One end of the push rod 32 is connected to the connecting part 22, and the other end is provided in the slide 312 and abuts against the push handle 33.

[0086] In some embodiments, the push handle 33 is sleeved on the outer periphery of the fixing member 31, or the fixing member 31 is sleeved on the outer periphery of the push handle 33.

[0087] In some embodiments, the pushing assembly 30 includes an elastic element 34. The elastic element 34 can be selected from springs with appropriate elastic force and length according to actual needs, so that the elastic element 34 can simultaneously abut against the push handle 33 and the fixing member 31, and the push rod 32 passes through the elastic element 34. When the push handle 33 is pushed manually or by a power element such as a cylinder, the push handle 33 drives the push rod 32 to rise, and the elastic element 34 is in a compressed state. When the pressure acting on the elastic element 34 is released, the elastic element 34 returns the position of the push handle 33 by elastic force, and causes the push plate 20 to fall.

[0088] In some embodiments, the pushing assembly 30 includes a connector 35 disposed within the receiving cavity 311, and the connecting portion 22 is connected to the push rod 32 via the connector 35. The push rod 32 drives the connector 35 to rise, and the connector 35 drives the main body 21 to push the consumable 201 mounted on the second protrusion 12, which helps to improve the stability of the push plate 20's movement.

[0089] Please see Figure 9 Another embodiment of this application provides a thermoforming apparatus 300, including a first robot arm 310, a preheating furnace 320, a second robot arm 330, a forming mold 340, and a preheating fixture 200 as described in any of the above embodiments. The first robot arm 310 is used to place the preheating fixture 200 carrying the part to be formed into the preheating furnace 320, and the second robot arm 330 is used to move the preheating fixture 200 carrying the preheated part to be formed into the forming mold 340.

[0090] Taking the replacement of consumable 201 on the preheating fixture 200 on the first robotic arm 310 as an example, when the thermoforming device 300 is in use, the first robotic arm 310 first moves the preheating fixture 200 to the material changing device 100. The first positioning block 111, the second positioning block 112, and the third positioning block 113 are connected through the side wall of the preheating fixture 200. After positioning the preheating fixture 200, the first protrusion 203 contacts the second protrusion 12. The fastener 101, which can be a bolt, is loosened by a tool, so that the used consumable 201 on the first protrusion 203 falls under the action of gravity and is fitted onto the second protrusion 12. The first robotic arm 310 moves the preheating fixture 200 away from the material changing device 100, and the pusher assembly 30 drives the pusher plate 20 to rise, separating the used consumable 201 from the second protrusion 12. Then, a new consumable 201 is placed on the second protrusion 12. The first robotic arm 310 moves the preheating fixture 200 to the material changing device 100 for repositioning, pushes the component 30 to lift the push plate 20, pushes the new consumable 201 into the recess 202, and fits it onto the first protrusion 203. After re-locking the fastener 101, the first robotic arm 310 moves the preheating fixture 200 to the material unloading position of the preheating furnace 320 to place the parts to be preheated.

[0091] Those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the spirit and essence of this application fall within the scope of this application's disclosure.
