Description

[0002] In the production process of glass door refrigerators, the pressing and bonding of glass panel and door frame is an important part. Especially for frameless glass door, the connection between glass panel and door frame depends entirely on the adhesive between glass panel and door frame (the adhesive is applied on the panel bonding part of door frame), so the glass panel and door frame must be tightly bonded together before foaming can be performed.

[0003] When the glass panel is pressed and bonded to the door frame, it is necessary to ensure that the door frame and the glass panel are accurately positioned, usually by setting up a positioning tool for positioning.

[0004] The positioning tool in the prior art can usually only position the circumferential outer side of the door frame, that is, apply a thrust to the door frame from the circumferential outer side to fix the door frame. However, since the door frame is usually made of sheet metal or PCM or VCM dedicated to refrigerator door frames, the thickness is relatively thin and the hardness is not very high, the thrust from the circumferential outer side alone may cause the door frame to deform, thereby affecting the quality of the refrigerator glass door and causing waste.

[0063] Reference Figure 1 In some embodiments of the present application, a refrigerator glass door compression bonding device is provided, including a refrigerator glass door compression bonding positioning tool 1000 and a pressing device.

[0064] Among them, the refrigerator glass door pressing and bonding positioning tool 1000 is used to position the door frame 3100 and the glass panel 3200 of the refrigerator glass door 3000 when the glass panel 3200 of the refrigerator glass door 3000 is pressed and bonded with the door frame 3100, so that the door frame 3100 and the glass panel 3200 can be quickly calibrated for bonding.

[0065] The pressing device is escalably disposed above the refrigerator glass door pressing and bonding positioning tool 1000, and is used to provide downward pressure on the glass panel 3200 when the glass panel 3200 is bonded to the door frame 3100. When the door frame 3100 and the glass panel 3200 are positioned in place on the refrigerator glass door pressing and bonding positioning tool 1000, the pressing device is activated to provide downward pressure on the glass panel 3200, so that the glass panel 3200 and the door frame 3100 are bonded to form a finished glass door.

[0066] In some embodiments of the present application, the pressing device includes a pressing plate 2000 and a pressing driving component (omitted for illustration) that drives the pressing plate 2000 to realize a lifting action. The pressing driving component may be a cylinder, a hydraulic cylinder or an electric screw, etc. The pressing plate 2000 is installed on the lifting output end of the pressing driving component. The pressing plate 2000 moves downward to press the glass panel 3200 onto the panel bonding portion 3120 of the door frame 3100 (the panel bonding portion 3120 is covered with adhesive). After continuous downward pressure for a period of time, the glass panel 3200 will be firmly bonded to the door frame 3100.

[0067] In some embodiments of the present application, the pressing plate 2000 is made of soft material to avoid crushing the glass panel 3200. The area of ​​the pressing plate 2000 is not less than the area of ​​the glass panel 3200 so as to completely cover the glass panel 3200, so that the glass panel 3200 is evenly stressed and reliably bonded.

[0068] In some embodiments of the present application, the structure of the refrigerator glass door 3000 is as follows: Figure 1 As shown, refer to Figure 2 The refrigerator glass door 3000 has a rectangular overall profile, including a rectangular door frame 3100 and a rectangular glass panel 3200. The door frame 3100 includes a circumferential side plate 3110 (i.e., a left side plate, a right side plate, an upper side plate, and a lower side plate) and a first annular inner flange formed on the edge of one side of the circumferential side plate 3110 of the door frame 3100 (specifically, the front side of the door frame 3100 when the refrigerator glass door 3000 is installed). The first annular inner flange is vertically connected to the circumferential side plate 3110 of the door frame 3100 and is located on the inner side of the circumferential side plate 3110, i.e., folded toward the inside of the door frame 3100. The first annular inner flange constitutes a panel bonding portion 3120 of the door frame 3100. The glass panel 3200 is bonded to and covers the panel bonding portion 3120 of the door frame 3100 to form a frameless glass door.

[0069] In some embodiments of the present application, reference Figures 3 to 11 The refrigerator glass door pressing and bonding positioning tool 1000 includes a glass panel positioning component, a door frame outer positioning mechanism 1200 and a door frame inner positioning mechanism 1300.

[0070] In some embodiments of the present application, the refrigerator glass door 3000 pressing and bonding tooling also includes a supporting base plate 1400, and the glass panel positioning assembly, the door frame outer positioning mechanism 1200 and the door frame inner positioning mechanism 1300 are arranged on the supporting base plate 1400, so that the refrigerator glass door 3000 pressing and bonding tooling becomes an integral structure, which is convenient for overall transportation.

[0071] The glass panel positioning assembly includes a plurality of glass panel positioning components 1100 , which are arranged along the circumferential direction and are used to position the glass panel 3200 from the circumferential outer side of the glass panel 3200 .

[0072] The door frame outer positioning mechanism 1200 includes an outer driving component 1210, two adjacent outer fixed positioning plates 1220 and two adjacent outer movable positioning plates 1230. The outer fixed positioning plates 1220 and the outer movable positioning plates 1230 are surrounded by a rectangular frame shape, which respectively correspond to the four circumferential side plates of the door frame 3100. The outer fixed positioning plates 1220 are fixed and stationary, and the two adjacent outer fixed positioning plates 1220 are vertically arranged as the positioning reference of the door frame 3100; the two adjacent outer movable positioning plates 1230 are vertically arranged and arranged one by one with the two outer fixed positioning plates 1220. The outer fixed positioning plates 1220 and the outer movable positioning plates 1230 work together to position the door frame 3100 from the outer side of the circumferential side plates 3110 of the door frame 3100.

[0073] The inner positioning mechanism 1300 of the door frame is located on the inner side of the outer positioning mechanism 1200 of the door frame, and includes an inner driving component 1310, and an inner movable positioning plate 1320 which is arranged correspondingly to the outer fixed positioning plate 1220 and the outer movable positioning plate 1230, that is, the inner movable positioning plates 1320 are arranged in four corresponding places to form a rectangular frame shape, which are respectively arranged opposite to the two outer movable positioning plates 1230 and the two outer fixed positioning plates 1220, and are used to position the door frame 3100 from the inner side of the circumferential side plate 3110 of the door frame 3100 and from below the panel bonding part 3120 of the door frame 3100.

[0074] The outer fixed positioning plate 1220, the outer movable positioning plate 1230 and the inner movable positioning plate 1320 form an annular positioning space 1500 for accommodating the door frame 3100. When the glass panel 3200 is bonded, the door frame 3100 is positioned in the annular positioning space 1500. The outer movable positioning plate 1230 is a moving part, which can move inward or outward relative to the center of the annular positioning space 1500 under the drive of the outer driving component 1210, that is, move in a direction close to or away from the door frame 3100; the inner movable positioning plate 1320 is also a moving part, which can also move inward or outward relative to the center of the annular positioning space 1500 under the drive of the inner driving component 1310, that is, move in a direction close to or away from the door frame 3100.

[0075] During positioning, the outer movable positioning plate 1230 and the inner movable positioning plate 1320 move toward each other synchronously, that is, the outer movable positioning plate 1230 moves inwardly, and synchronously, the inner movable positioning plate 1320 moves outwardly, until the inner movable positioning plate 1320, the outer movable positioning plate 1230, and the outer fixed positioning plate 1220 all abut against the door frame 3100, and the three cooperate to clamp and position the door frame 3100. Figure 7 shown.

[0076] When the outer movable positioning plate 1230 and the inner movable positioning plate 1320 move in opposite directions, that is, the outer movable positioning plate 1230 moves outward under the drive of the outer driving component 1210, and the inner movable positioning plate 1320 moves inward under the drive of the inner driving component 1310, the width of the annular positioning space 1500 increases, thereby facilitating the placement of the front door frame 3100 for bonding and the removal of the glass door after bonding is completed.

[0077] The refrigerator glass door pressing and bonding positioning tool 1000 in the embodiment of the present application jointly positions the door frame 3100 from the outside and inside of the door frame 3100 through the door frame outer positioning mechanism 1200 and the door frame inner positioning mechanism 1300, and simultaneously positions the glass panel 3200 through the glass panel 3200 assembly, thereby ensuring that the door frame 3100 and the glass panel 3200 are accurately and reliably positioned.

[0078] Moreover, the positioning force of the outer fixed positioning plate 1220 and the outer movable positioning plate 1230 on the circumferential side plate 3110 of the door frame 3100 is in opposite direction to the positioning force of the inner movable positioning plate 1320 on the circumferential side plate 3110 of the door frame 3100, which can effectively reduce or even avoid the deformation of the circumferential side plate 3110 of the door frame 3100.

[0079] At the same time, the inner movable positioning plate 1320 also applies a positioning force to the panel bonding part 3120 of the door frame 3100 from below the panel bonding part 3120 of the door frame 3100, which is opposite to the downward pressure direction of the pressing device on the glass panel 3200, and can effectively reduce or even avoid the deformation of the panel bonding part 3120 of the door frame 3100 under stress.

[0080] In summary, the refrigerator glass door pressing and bonding positioning tool 1000 in the embodiment of the present application can effectively prevent the door frame 3100 from deforming, ensure the quality of the glass door pressing and bonding, and reduce the scrap rate while ensuring the accurate and reliable positioning of the door frame 3100 and the glass.

[0081] Accordingly, the refrigerator glass door pressing and bonding equipment in the embodiment of the present application can realize the rapid positioning and calibration of the door frame 3100 and the glass panel 3200, thereby improving the pressing and bonding efficiency of the refrigerator glass door 3000. During bonding, the pressing device applies pressure to the glass panel 3200, thereby reducing the number of times people touch the glass panel 3200, and easily ensuring that the glass panel 3200 is subjected to balanced force, thereby improving the pressing and bonding quality of the glass door.

[0082] When the refrigerator glass door pressing and bonding equipment in the embodiment of the present application is used to press and bond the refrigerator glass door 3000, the door frame 3100 is first placed in the annular positioning space 1500, and the door frame outer positioning mechanism 1200 and the door frame inner positioning mechanism 1300 move synchronously to position the door frame 3100, and then the panel bonding part 3120 of the door frame 3100 is covered with adhesive (such as injected glass adhesive), and then the glass panel 3200 is placed and positioned by the glass panel positioning assembly, so that the glass panel 3200 and the door frame 3100 are aligned up and down; then the pressing device is started, the pressing plate 2000 descends and presses on the glass panel 3200, the glass panel 3200 moves down, and is bonded with the adhesive on the door frame 3100, and the pressure is maintained for a certain period of time; then the pressing device is reset, and the pressing plate 2000 rises; finally, the glass door is taken out, and a working cycle ends.

[0083] In some embodiments of the present application, the outer fixed positioning plate 1220 and the outer movable positioning plate 1230 are configured to fit against the outer wall of the circumferential side plate 3110 of the door frame 3100 during positioning; that is, the inner wall of the outer movable positioning plate 1230 and the outer fixed positioning plate 1220 are adapted to the outer wall contour of the circumferential side plate 3110 of the door frame 3100. For example, if the outer wall of the circumferential side plate 3110 of the door frame 3100 is a plane, the inner wall of the outer fixed positioning plate 1220 and / or the outer movable positioning plate 1230 is a corresponding plane; if the outer wall of the circumferential side plate 3110 of the door frame 3100 is a profiled surface, the inner wall of the outer fixed positioning plate 1220 and / or the outer movable positioning plate 1230 is a corresponding profiled surface; so that the outer fixed positioning plate 1220 and the outer movable positioning plate 1230 can fully fit against the outer wall of the circumferential side plate 3110 of the door frame 3100 during positioning, thereby improving the positioning effect.

[0084] In order to enable the inner movable positioning plate 1320 to simultaneously position the door frame 3100 from the inner side of the circumferential side plate 3110 of the door frame 3100 and from below the panel bonding portion 3120 of the door frame 3100, in some embodiments of the present application, such as Figures 6 to 9 , Fig.11 As shown, the inner movable positioning plate 1320 includes a first inner positioning portion 1321 and a second inner positioning portion 1322. When positioned, the first inner positioning portion 1321 fits and abuts against the inner wall of the circumferential side plate 3110 of the door frame 3100, applying an outward supporting force to the circumferential side plate 3110 of the door frame 3100, and the second inner positioning portion 1322 fits and abuts against the panel bonding portion 3120 of the door frame 3100, applying an upward supporting force to the panel bonding portion 3120 of the door frame 3100.

[0085] The first inner positioning portion 1321 and the second inner positioning portion 1322 can be two different parts of the same structural component, such as the side surface and the top surface of the inner movable positioning plate 1320, or they can be respectively arranged on different structural components.

[0086] In order to reduce the weight of the inner movable positioning plate 1320 as much as possible, thereby reducing the driving capacity requirements for the internal driving component 1310 and reducing the production cost, the inner movable positioning plate 1320 is a multiple split component assembly structure, including a plate body 1323, a side positioning plate 1324 and a top positioning plate 1325.

[0087] Among them, the plate body 1323 is a long strip plate extending horizontally and placed vertically, which is connected to the output end of the internal driving component 1310, and the side positioning plate 1324 and the top positioning plate 1325 are both long strip plates extending horizontally and placed horizontally, and the side positioning plate 1324 is fixed on the outer surface of the plate body 1323, and the top positioning plate 1325 is fixed on the top surface of the plate body 1323, and the top positioning plate 1325 and the side positioning plate 1324 are separated by a certain distance up and down.

[0088] The first inner positioning portion 1321 is the outer side surface of the side positioning plate 1324, and the second positioning portion 1120 is the top surface of the top positioning plate 1325. During positioning, the first inner positioning portion 1321, i.e., the outer side surface of the side positioning plate 1324, is in contact with the circumferential side plate 3110 of the door frame 3100, and the second positioning portion 1120, i.e., the top surface of the top positioning plate 1325, is in contact with the panel bonding portion 3120 of the door frame 3100.

[0089] In some embodiments of the present application, the second inner positioning portion 1322 also fits against the inner wall of the circumferential side plate 3110 of the door frame 3100, that is, in addition to supporting and positioning the panel bonding portion 3120 of the door frame 3100, it can also play a certain positioning role on the circumferential side plate 3110 of the door frame 3100, thereby improving the inner positioning effect of the door frame 3100.

[0090] In some embodiments of the present application, the other opposite side (i.e., the side panel 3110 of the door frame 3100) Figure 2 As shown in the installation state perspective of the refrigerator glass door 3000, a second annular inner flange 3130 is formed on the edge of this side (i.e., the rear side of the door frame 3100), and the second annular inner flange 3130 is vertically connected to the circumferential side plate 3110 of the door frame 3100 and is located on the inner side of the circumferential side plate 3110 of the door frame 3100.

[0091] Correspondingly, a door frame support portion 1600 arranged circumferentially is formed in the annular positioning space 1500, and the second annular inner flange 3130 of the door frame 3100 is supported on the door frame support portion 1600. The door frame support portion 1600 raises the door frame 3100 to a certain height for easy operation.

[0092] like Figure 6 and Fig. 9As shown, the door frame support portion 1600 can be a ring-shaped portion formed by splicing a plurality of strip-shaped support plates, so as to have a larger contact area with the second annular inner flange 3130 of the door frame 3100, thereby preventing the second annular inner flange 3130 from being deformed due to local concentrated force when the door frame 3100 is compressed. The door frame support portion 1600 can be fastened to the support base plate 1400 by a plurality of support columns arranged along the circumferential direction.

[0093] In some embodiments of the present application, Figure 1 , Figure 3 , Figures 7 to 10 As shown, the door frame outer positioning mechanism 1200 also includes an outer guide assembly 1240 for guiding the movement of the outer movable positioning plate 1230 to achieve smooth movement of the outer movable positioning plate 1230 and improve movement balance and stability; Figure 1 , Figure 3 , Figures 7 to 9 , Fig.11 As shown, the door frame inner positioning mechanism 1300 also includes an inner guide assembly 1330 for guiding the movement of the inner movable positioning plate 1320 to achieve smooth movement of the inner movable positioning plate 1320 and improve movement balance and stability.

[0094] In some embodiments of the present application, the outer guide assembly 1240 and the inner guide assembly 1330 are both guide rail and slider assemblies, the guide rails are fixed on the support base plate 1400, and the sliders are correspondingly fixed on the outer movable positioning plate 1230 and the inner movable positioning plate 1320. Of course, other guide structures may also be used, such as guide column and guide sleeve structures, etc., and no specific limitation is made to this.

[0095] In some embodiments of the present application, the external drive component 1210 is arranged in a one-to-one correspondence with the external movable positioning plate 1230, and the external drive component 1210 is located in the middle position of the outer side of the external movable positioning plate 1230. The outer guide components 1240 are symmetrically arranged on the left and right sides of the external drive component 1210 to further improve the movement stability of the external movable positioning plate 1230.

[0096] Similarly, the inner driving component 1310 and the inner movable positioning plate 1320 are arranged in a one-to-one correspondence. The inner driving component 1310 is located in the inner middle position of the inner movable positioning plate 1320, and the inner guide components 1330 are symmetrically arranged on the left and right sides of the inner driving component 1310 to further improve the movement stability of the inner movable positioning plate 1320.

[0097] The above-mentioned external driving component 1210 and internal driving component 1310 may be driving components such as a cylinder, a hydraulic cylinder or an electric lead screw slider structure that can realize the linear reciprocating motion of the moving parts, and no specific limitation is made here.

[0098] Regarding the glass panel positioning assembly, in some embodiments of the present application, the plurality of glass panel positioning components 1100 thereof are configured to abut against the circumferential side surfaces of the glass panel 3200 during positioning, so as to improve the positioning effect.

[0099] In some embodiments of the present application, a plurality of glass panel positioning components 1100 are spaced apart on an outer fixed positioning plate 1220 and an outer movable positioning plate 1230, specifically located at the top of the outer fixed positioning plate 1220 and the outer movable positioning plate 1230, and protrude upward from the outer fixed positioning plate 1220 and the outer movable positioning plate 1230 so as to contact and abut against the circumferential outer side of the glass panel 3200 above the door frame 3100.

[0100] The glass panel positioning component 1100 on the external movable positioning plate 1230 can move inward or outward together with the external movable positioning plate 1230. When the external movable positioning plate 1230 moves inward to the positioning position and positions the door frame 3100 in place, the glass panel positioning component 1100 thereon also moves to the positioning position so that it can position the glass panel 3200 when the glass panel 3200 is placed subsequently.

[0101] The glass panel positioning component 1100 is arranged on the outer fixed positioning plate 1220 and the outer movable positioning plate 1230. There is no need to set up a separate structural component to support and install the glass panel positioning component 1100, which is conducive to simplifying the structure of the entire tooling, reducing space occupancy, and will not interfere with the movement of the outer movable positioning plate 1230 and the inner movable positioning plate 1320.

[0102] In some embodiments of the present application, Fig.10 As shown, each glass panel positioning component 1100 includes a fixing portion 1110, a positioning portion 1120 and an adjusting portion 1130. The fixing portion 1110 is fixed on an outer fixed positioning plate 1220 or an outer movable positioning plate 1230. The positioning portion 1120 is used to fit against the circumferential side of the glass panel 3200. The adjusting portion 1130 connects the positioning portion 1120 and the fixing portion 1110.

[0103] For the glass panel positioning component 1100 on the external fixed positioning plate 1220, a guide groove 1250 is formed on the external fixed positioning plate 1220, and the guiding direction of the guide groove 1250 is horizontal and perpendicular to the circumferential side of the glass panel 3200, and the positioning part 1120 cooperates with the guide groove 1250 for sliding guidance; similarly, for the glass panel positioning component 1100 on the external movable positioning plate 1230, a guide groove 1250 is formed on the external movable positioning plate 1230, and the guiding direction of the guide groove 1250 is horizontal and perpendicular to the circumferential side of the glass panel 3200, and the positioning part 1120 cooperates with the guide groove 1250 for sliding guidance.

[0104] By operating the adjustment portion 1130, the positioning portion 1120 can be slidably adjusted relative to the guide groove 1250, so that the positioning portion 1120 can be moved and adjusted in a direction closer to or away from the glass panel 3200 to adapt to the positioning of glass panels 3200 of different sizes; it can also be used to readjust the glass panel positioning component 1100 to ensure its positioning accuracy when the positioning accuracy has deteriorated due to long-term use.

[0105] In some embodiments of the present application, reference Fig.12 and Fig.13 The adjusting portion 1130 is an adjusting bolt, and the fixing portion 1110 is provided with a through portion 1111, so that the stud of the adjusting bolt can pass through the fixing portion 1110 and then be screwed together with the threaded hole on the positioning portion 1120, and a limiting protrusion 1131 is provided on the stud of the adjusting bolt to limit the axial movement freedom of the adjusting bolt, so that the adjusting bolt can only rotate but not axially move; at the same time, since the positioning portion 1120 is slidably matched with the guide groove 1250, and the adjusting bolt is screwed together with the positioning portion 1120, when the adjusting bolt is rotated, the sliding adjustment of the positioning portion 1120 along the guide groove 1250 can be realized;

[0106] After being adjusted into place, the positioning portion 1120 can be tightened by means of a top screw provided on the fixing portion 1110 (a top screw hole 1112 is provided on the fixing portion 1110 for installing the top screw) so that the positioning portion 1120 is positioned at the adjusted position, so that the glass panel 3200 can be positioned stably.

[0107] In some embodiments of the present application, Figures 6 to 9 As shown, refer to Fig.14 The glass panel positioning assembly further includes a glass panel support component 1140 located inside the shaped positioning space for supporting the glass panel 3200; the glass panel support component 1140 is configured to support the glass panel 3200 at a certain height above the panel bonding portion 3120 of the door frame 3100 before the glass panel 3200 is pressed and bonded, such as Figure 6 When the glass panel 3200 is pressed and bonded, the glass panel support member 1140 and the glass panel 3200 are synchronously lowered to avoid bonding of the glass panel 3200 and the door frame 3100.

[0108] That is, the glass panel support component 1140 has a certain lifting and retracting ability, and it only drops slightly when it is only affected by the gravity of the glass panel 3200, so that there is no contact between the glass panel 3200 and the panel bonding part 3120 of the door frame 3100, and there is a certain gap. Therefore, at this time, the glass panel 3200 will not contact the adhesive on the panel bonding part 3120 of the door frame 3100, so that the glass panel 3200 can be smoothly adjusted and positioned under the action of multiple glass panel positioning components 1100.

[0109] When the glass panel 3200 is also positioned in place, the pressing device presses down on the glass panel 3200, thereby pressing the glass panel supporting component 1140 down, so that the glass panel 3200 falls on the panel bonding part 3120 of the door frame 3100. After maintaining pressure for a period of time, the glass panel 3200 is firmly bonded to the door frame 3100.

[0110] like Figure 7 and Fig.14 As shown, the glass panel support component 1140 is a piston component that is lifted and lowered by inflation and deflation of air, and is installed on the support base plate 1400 through a mounting bracket. A inflation and deflation interface 1141 is provided on the piston component to connect to a gas storage device; alternatively, the glass panel support component 1140 may also be an elastic member with a certain elastic deformation capability, such as a spring, a rubber column, etc. A plurality of glass panel support components 1140 are located below the four corners of the glass panel 3200, and in an idle area between two adjacent inner movable positioning plates 1320 to make full use of the space.

[0111] In some embodiments of the present application, a refrigerator glass door compression bonding and positioning tool 1000 includes a glass panel positioning assembly, a door frame outer positioning mechanism 1200 , a door frame inner positioning mechanism 1300 and a supporting bottom plate 1400 .

[0112] The glass panel positioning assembly is used to position the glass panel 3200 from the circumferential outer side of the glass panel 3200 .

[0113] The door frame outer positioning mechanism 1200 is used to position the door frame 3100 from the outer side of the circumferential side plate 3110 of the door frame 3100 .

[0114] The door frame inner positioning mechanism 1300 is used to position the door frame 3100 from the inner side of the circumferential side plate 3110 of the door frame 3100 and from below the panel bonding portion 3120 of the door frame 3100 .

[0115] The door frame outer positioning mechanism 1200 , the door frame inner positioning mechanism 1300 and the glass panel positioning assembly are arranged on the supporting base plate 1400 .

[0116] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0117] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
