Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigerator manufacturing, and more specifically, to an automatic positioning mechanism for the inner lining of a door. Background Technology
[0002] In the research on automatic blanking of the waste material around the door lining, two issues arise. First, due to the unique structure of the door lining, the formed lining is thin and low in height, making it prone to deformation, warping, and misalignment, resulting in difficult positioning. Second, the fully automated control of the blanking process for the door lining requires that the positioning process also possess automatic positioning and adjustment functions. Therefore, it is necessary to research an automatic positioning mechanism for the door lining that not only addresses the impact of door lining warping and deformation but also automatically positions and corrects the material to ensure positioning accuracy.

[0023] Compared with the prior art, the present invention has the following beneficial effects: In the embodiments of the present invention, the automatic positioning mechanism for door lining edge marking is used to automatically position the door lining before edge marking. The automatic positioning mechanism for door lining edge marking includes a base, a door lining shape positioning component, an automatic adjustment component, and a groove positioning component. The base is used to install the door lining shape positioning component, the automatic adjustment component, and the groove positioning component. The door lining shape positioning component is used to perform shape positioning on the door lining, i.e., coarse positioning. The groove positioning component is used to achieve precise positioning of the door lining by positioning with the Ω groove on the door lining.

After positioning is completed, the door lining is then slicing. This embodiment of the invention can achieve automatic positioning of the door lining without manual operation, reducing process quality defects, and has the characteristics of accurate positioning and high degree of automation.

[0039] Please see Figure 1 and Figure 2 This utility model embodiment provides an automatic positioning mechanism 100 for door lining edge marking. This automatic positioning mechanism 100 for door lining edge marking can realize the automatic positioning of the door lining without manual operation, reduce process quality defects, and has the characteristics of accurate positioning and high degree of automation.
[0040] like Figures 1 to 4As shown in this embodiment of the present invention, the automatic positioning mechanism 100 for lining cutting is used to position the lining so as to automatically position the lining when cutting it. In this embodiment, the automatic positioning mechanism 100 for door lining edge marking includes: a base 110; a door lining shape positioning member 120 connected to the base 110 for positioning the door lining shape; an automatic adjustment component 130 mounted on the base 110; and a slot positioning component 140 including a first positioning member 141 and a second positioning member 142, both mounted on the base 110, forming a positioning slot 143 between the first positioning member 141 and the second positioning member 142. The automatic adjustment component 130 is connected to the second positioning member 142 for adjusting the gap between the second positioning member 142 and the first positioning member 141, thereby adjusting the size of the positioning slot 143 so that the positioning slot 143 corresponds to the Ω slot of the door lining.
[0041] It should be noted that, in this embodiment of the present invention, the automatic positioning mechanism 100 for lining edge marking is used to automatically position the lining before edge marking. The automatic positioning mechanism 100 includes a base 110, a lining shape positioning component 120, an automatic adjustment component 130, and a groove positioning component 140. The base 110 is used to mount the lining shape positioning component 120, the automatic adjustment component 130, and the groove positioning component 140. The lining shape positioning component 120 is used to perform shape positioning on the lining, i.e., to perform coarse positioning on the lining. The slot positioning assembly 140 is used to achieve precise positioning of the door lining by positioning with the Ω slot on the door lining. The automatic adjustment assembly 130 is used to achieve automatic positioning of the Ω slot on the door lining by the slot positioning assembly 140. The first positioning member 141 and the second positioning member 142 are used to form the positioning groove 143. The second positioning member 142 cooperates with the automatic adjustment assembly 130. The automatic adjustment assembly 130 can realize the movement of the second positioning member 142, thereby adjusting the gap width between the first positioning member 141 and the second positioning member 142, that is, adjusting the width of the positioning groove 143.
[0042] It should also be noted that in this embodiment of the invention, when the door lining enters the slicing step, the door lining is first initially positioned by the door lining shape positioning member 120. At this time, the gap between the first positioning member 141 and the second positioning member 142 is relatively wide, that is, the width of the positioning groove 143 is relatively large, so as to facilitate the rough positioning of the door lining. Then, after the door lining mates with the door lining shape positioning member 120, the automatic adjustment component 130 moves the second positioning member 142 toward the first positioning member 141, reducing the width of the positioning groove 143 until it clamps the Ω groove of the door lining, thereby achieving automated positioning of the door lining. After positioning is completed, the door lining is then slicing. This embodiment of the invention can achieve automatic positioning of the door lining without manual operation, reducing process quality defects, and has the characteristics of accurate positioning and high degree of automation.
[0043] like Figure 3 As shown, in an optional embodiment, the automatic adjustment component 130 may include a translational positioning cylinder 131 and a guide rail 132. The translational positioning cylinder 131 is mounted on the base 110 and is connected to the second positioning member 142 in a transmission manner. The guide rail 132 is connected to the base 110 and the second positioning member 142 respectively. The translational positioning cylinder 131 is used to drive the second positioning member 142 to slide along the guide rail 132 to adjust the gap width between the second positioning member 142 and the first positioning member 141.
[0044] It should be understood that the translational positioning cylinder 131 is used to drive the second positioning member 142 to move linearly, and the guide rail 132 is used to limit and guide the movement of the second positioning member 142. Further, as shown in the figure, the first positioning member 141 and the second positioning member 142 comprise four sets, respectively arranged near the four sides of the door lining, with automatic adjustment components 130 corresponding to the second positioning members 142. For each side of the second positioning member 142, an automatic adjustment component 130 is designed; that is, the translational positioning cylinder 131 and the guide rail 132. The matching design of the translational positioning cylinder 131 and the guide rail 132 enables stable adjustment of the second positioning member 142, thereby ensuring accurate and efficient adjustment.
[0045] Optionally, such as Figure 3 As shown, in this embodiment, the guide rail 132 can be a rail mounted on the base 110, and a matching groove is designed on the second positioning member 142. Of course, it is not limited to this; in other embodiments of this utility model, the guide rail 132 and the groove can also be designed with other structural forms.
[0046] Furthermore, in this embodiment, the aforementioned automatic adjustment component 130 further includes a limiting corner block 133. The limiting corner block 133 is mounted on the base 110 and spaced apart from the second positioning member 142, used to limit the movement of the second positioning member 142. The limiting corner block 133 is generally designed at the outward position of four fixed points on the inner lining of the door. The limiting corner block 133 is used to limit the movement of the second positioning member 142 to limit the maximum range of movement of the second positioning member 142, that is, the maximum value of the gap between the second limiting member and the first limiting member. In this embodiment, the limiting corner block 133 includes a first limiting part 1331 and a second limiting part 1332, which are arranged at right angles to limit two adjacent second positioning members 142.
[0047] In this embodiment, the automatic adjustment component 130 further includes a long-side limiting member 134. The long-side limiting member 134 is mounted on the base 110 and adjacent to the guide rail 132. The long-side limiting member 134 corresponds to the limiting corner block 133 to limit the movement of the second positioning member 142 located on the long side of the door lining. The long-side limiting member 134 is used to limit the movement of the second positioning member 142 located on the long side of the door lining. Since the second positioning member 142 located on the long side is relatively long, the setting of the long-side limiting member 134 can ensure that the movement of the second positioning member 142 on that side is more stable.
[0048] Please see Figures 3 to 5 In an optional embodiment, multiple translational positioning cylinders 131 and guide rails 132 are included. Furthermore, the multiple translational positioning cylinders 131 and guide rails 132 are staggered to improve stability.
[0049] like Figure 6 As shown, in an optional embodiment, the slot positioning assembly 140 further includes an adjustable fixing member 144. The first positioning member 141 is mounted on the base 110 via the adjustable fixing member 144, which is used to adjust and fix the first positioning member 141. Optionally, the adjustable fixing member 144 can be an adjustable mounting screw, which allows for convenient adjustment of the first positioning member 141.
[0050] like Figure 3 As shown, further, in this embodiment, the end of the first positioning member 141 is wedge-shaped, and the end of the second positioning member 142 is wedge-shaped. Of course, this is not the only possibility. In other embodiments of this utility model, the ends of the first positioning member 141 and the ends of the second positioning member 142 may not be wedge-shaped simultaneously. This utility model does not impose specific requirements or limitations on this.
[0051] This utility model also provides an automatic positioning mechanism 100 for scribbling door linings, used for positioning door linings. The automatic positioning mechanism 100 includes: a base 110; a door lining shape positioning member 120 connected to the base 110 for shape positioning of the door lining; an automatic adjustment assembly 130 mounted on the base 110; and a slot positioning assembly 140, which includes a first positioning member 141 and a second positioning member 142. Both the first positioning member 141 and the second positioning member 142 are mounted on the base 110, and a positioning groove 143 is formed between the first positioning member 141 and the second positioning member 142. The automatic adjustment component 130 is connected to the second positioning member 142 to adjust the width of the positioning groove 143. The automatic adjustment component 130 is used to move the second positioning member 142 away from the first positioning member 141 in the first working state, and to move the second positioning member 142 closer to the first positioning member 141 in the second working state, so that the positioning groove 143 corresponds to the Ω groove of the door lining.
[0052] It should be understood that in the first working state, the distance between the first positioning member 141 and the second positioning member 142 is relatively large (but the second limiting member is still limited to the inside of the limiting corner block 133 and the long side limiting member 134). At this time, the door lining can be quickly positioned in conjunction with the door lining shape positioning member 120. Then, it enters the second working state, that is, the second positioning member 142 moves closer to the first positioning member 141 and the positioning groove 143 corresponds to the Ω groove of the door lining. By limiting the Ω groove of the door lining with the second positioning member 142 and the first positioning member 141, the precise positioning of the door lining is achieved. In this embodiment, automatic positioning adjustment is achieved by the automatic adjustment component 130. The automatic positioning mechanism 100 for door lining edge marking can achieve automatic positioning of the door lining without manual operation, reducing process quality defects, and has the characteristics of accurate positioning and high degree of automation.
[0053] Please refer to the following: Figures 1 to 7The automatic positioning mechanism 100 for door lining edge marking provided in this embodiment of the utility model is used to automatically position the door lining before edge marking. The automatic positioning mechanism 100 includes a base 110, a door lining shape positioning component 120, an automatic adjustment component 130, and a groove positioning component 140. The base 110 is used to install the door lining shape positioning component 120, the automatic adjustment component 130, and the groove positioning component 140. The door lining shape positioning component 120 is used to perform shape positioning of the door lining, that is, to perform coarse positioning of the door lining. The slot positioning assembly 140 is used to achieve precise positioning of the door lining by positioning with the Ω slot on the door lining. The automatic adjustment assembly 130 is used to achieve automatic positioning of the Ω slot on the door lining by the slot positioning assembly 140. The first positioning member 141 and the second positioning member 142 are used to form the positioning groove 143. The second positioning member 142 cooperates with the automatic adjustment assembly 130. The automatic adjustment assembly 130 can realize the movement of the second positioning member 142, thereby adjusting the gap width between the first positioning member 141 and the second positioning member 142, that is, adjusting the width of the positioning groove 143. When the door lining enters the slitting step, the door lining is first initially positioned by the door lining shape positioning member 120. At this time, the gap between the first positioning member 141 and the second positioning member 142 is relatively wide, that is, the width of the positioning groove 143 is relatively large, so as to facilitate the rough positioning of the door lining. Then, after the door lining mates with the door lining shape positioning member 120, the automatic adjustment component 130 moves the second positioning member 142 toward the first positioning member 141, reducing the width of the positioning groove 143 until it clamps the Ω groove of the door lining, thereby achieving automatic positioning of the door lining. After positioning is completed, the door lining is then slitting.
[0054] Meanwhile, it should also be noted that after the door lining is vacuum-formed, it can be transferred to the top of the door lining edge-marking automatic positioning mechanism 100 by a robotic arm; the robotic arm suction cup is released, and the door lining falls onto the door lining edge-marking automatic positioning mechanism 100; at this time, the positioning groove 143 formed by the first positioning member 141 and the second positioning member 142 is wider (i.e., the positioning groove 143 is in the open state, the first working state), so as to increase the fault tolerance rate of the door lining falling off and ensure that the Ω groove of the door lining falls accurately into the positioning groove 143 formed by the first positioning member 141 and the second positioning member 142; after the door lining and the door lining shape positioning member 120 are in place, the automatic adjustment component 130 (the translational positioning cylinder 131 receives the positioning signal) drives the second positioning member 142 to move inward to clamp the Ω groove of the door lining. At this time, the positioning groove 143 formed by the first positioning member 141 and the second positioning member 142 is narrower (i.e., the above positioning groove 143 is in the contracted state, the second working state), so as to achieve accurate positioning around the door lining. Next, the signal for the second positioning member 142 and the first positioning member 141 to be clamped in place can be transmitted to the control terminal through the automatic adjustment component 130. The pressing mechanisms on both sides fall and pre-press on the door lining, so that the upper and lower surfaces of the door lining and the automatic positioning mechanism 100 for edge marking of the door lining are tightly fitted, avoiding the impact of door lining warping. Then, the pressing mechanisms on both sides are controlled to move outward and press on the outer edge of the waste material around the door lining again. The cutter head of the equipment begins to cut the waste material. The waste material is pressed down before cutting, which can effectively avoid the door lining from undulating and shifting due to force during the edge marking process, ensuring the accuracy of the edge marking process. Automatic positioning can be achieved through the automatic positioning mechanism 100 for edge marking of the door lining. The pressing mechanism can ensure that the Ω groove surface around the door lining, as well as the upper and lower surfaces, are tightly fitted with the automatic positioning mechanism 100 for edge marking of the door lining, thereby overcoming the impact of door lining warping and deformation on edge marking accuracy, realizing automatic positioning and automatic correction of door lining edge marking. The structure is simple and the operation is fast. It can not only stably and reliably ensure product accuracy, but also realize automated production and meet production efficiency. This utility model embodiment can achieve automatic positioning of the door lining without manual operation, reducing process quality defects, and features precise positioning and a high degree of automation.
