Description

Technical Field

[0001] The invention relates to the technical field of hollow glass auxiliary devices, in particular to a composite tooling for hollow glass. Background Art

[0002] At present, in the insulating glass industry, first of all, there are certain processing errors between glass and keel, and during compounding, due to manual or equipment, only the relative position of one side can be guaranteed, and the error accumulates to the other side, making it difficult to ensure centering adjustment. The relative position errors between glass and glass, and between glass and keel are large, the assembly quality of insulating glass cannot be consistent, and the efficiency is low. When applied to some modular assembly projects, it seriously affects the quality of products or projects and the assembly quality. In terms of overall thickness after compounding: the composite of insulating glass requires that the actual thickness error range after compounding is limited; in terms of relative position between glass and glass, and glass and keel: after the composite of insulating glass, the upper glass and the lower glass on the same side are required to be on the same plane in the vertical direction. When the insulating glass is compounded, the glass and keel are required to be placed in the center. After the composite is completed, the vertical distance between the four sides of the glass and the four sides of the keel on the same side should be equal.

[0003] At the same time, in the application of ordinary insulating glass, due to the error between the two pieces of glass and the relative position error between the glass and the keel, it is difficult to ensure that the two pieces of glass and the keel are evenly stressed. Often, the convex components are stressed, which causes the insulating glass to have a reduced bearing capacity or burst. Taking these factors into consideration, there is an urgent need for an efficient, flexible, composite equipment that can achieve stable composite quality and reduce labor costs. Therefore, it is important to study how to ensure the relative position between glass and glass, glass and keel in the presence of errors in the real environment, and how to adjust the composite process equipment to the center. This is of great significance for improving the relative position dimensional accuracy of the insulating glass industry, increasing the overall strength of the insulating glass, reducing bursting, and modular assembly installation of insulating glass. Summary of the invention

[0004] In order to make up for the deficiencies of the prior art, the present invention provides a composite tooling for insulating glass which has a simple structure and is easy to use.

[0005] The present invention is achieved through the following technical solutions:

[0006] The composite tooling for hollow glass of the present invention is characterized in that it includes a rectangular frame, and a positioning device and a multi-directional linkage mechanism installed on the frame, wherein a plurality of positioning devices are used, and the positioning devices on the left and right sides of the frame are respectively connected to a first driving device and driven by the first driving device to move, and the first driving device is also connected to the multi-directional linkage mechanism, and the multi-directional linkage mechanism is connected to the positioning devices on the front and rear sides of the frame via a second driving device, thereby driving the movement of the positioning devices on the front and rear sides of the frame; the positioning device is used for positioning and aligning the outer edges of each layer of glass and the keel.

[0007] In the positioning device, a reset spring is sleeved on one end of the connecting shaft, and the other end is fixedly connected to a positioning pad, which can contact the outer edges of each layer of glass and the keel to position and align each layer of glass and the keel; the reset spring is located inside the frame, and one end of the connecting shaft is also located inside the frame and connected to the first drive device or the second drive device.

[0008] In the positioning device, the side of the positioning pad that contacts the keel adopts a boss structure, the high part of the boss contacts the outer side of the keel, the low part of the boss contacts each layer of glass, and the height of the boss corresponds to the preset height difference between the keel and the glass.

[0009] In the positioning device, the positioning pad is a nylon pad, and at least two connecting shafts are installed on one positioning pad; the starting end of the connecting shaft is tightly inserted into the hole on the synchronization rod to be fixedly connected to the synchronization rod, or the starting end of the connecting shaft is tightly inserted into the hole on the inclined block to be fixedly connected to the inclined block. There is a screw hole at the end of the connecting shaft, and there is a pre-embedded stud in the positioning pad. The stud is screwed into the screw hole of the connecting shaft to fix the connecting shaft and the positioning pad, and an adjustment gasket can be placed between the end face of the connecting shaft and the positioning pad.

[0010] The first driving device of the positioning devices on the left and right sides of the frame adopts a self-locking cam transmission device; the second driving device of the positioning devices on the front and rear sides of the frame adopts a slide block adjustment device.

[0011] The slider adjustment device includes two inclined blocks that contact each other through inclined surfaces, wherein inclined block one is fixedly connected to the connecting shaft of the positioning device, and inclined block two is connected to the multi-directional linkage device; the multi-directional linkage device pushes inclined block two to move horizontally, thereby pushing inclined block one to move longitudinally toward the glass, so that the positioning device pushes the front or rear side of each layer of glass and the keel for positioning and alignment.

[0012] The self-locking cam transmission device includes a rotating shaft, a cam fixed at one end of the rotating shaft, and a rotating handle fixed at the other end of the rotating shaft. The rotating shaft is rotatably installed on a frame, the rotating handle is located outside the frame, and the cam is located inside the frame. A self-locking plane is provided on one side of the cam. When the cam rotates, its self-locking plane can contact the multi-directional linkage device and the positioning device, so that the positioning device pushes the left or right side of each layer of glass and the keel for positioning and alignment.

Nuts are screwed on both sides of the screw on the synchronization rod respectively, and the synchronization rod is clamped by the two nuts on the screw to limit the insertion length of the screw on the synchronization rod. The relative position of the synchronization rod and the second bevel block is adjusted by rotating the nut, and then the relative displacement of the bevel block two and the inclined surface of the first bevel block is adjusted, thereby adjusting the stroke of the positioning device in the front and rear directions.

[0015] A friction-resistant and noise-reducing bushing is fixed at the contact point between the frame and the connecting shaft; a lifting handle is installed on the upper surface of the frame or on the outer side of the frame.

[0017] 1. This equipment is designed with a positioning device for the glass keel to ensure that the four sides are aligned during assembly, avoiding the eccentricity of the keel during compounding, and also ensuring the verticality of the upper and lower glass and keel. At the same time, the positioning pad is designed in a "convex" shape (convex platform) (such as Figure 5 As shown in the figure, it is completely fitted with the upper glass, the lower glass and the keel, which increases the overall strength of the insulating glass. When the side of the insulating window is stressed (that is, when the insulating glass is placed upright, the tooling is fixed around the insulating glass), it avoids the situation where only the glass is stressed, making the keel the main stress-bearing unit, reducing the risk of glass bursting;

[0018] 2. This equipment is designed with a slider adjustment device, and a width and length adjustment mechanism, which can adjust the relative position of the inclined block within a certain range according to the size of the glass or keel to meet the use requirements. It ensures the composite accuracy when there are errors in the glass or keel, and expands the use range of the tooling;

[0019] 3. This equipment is designed with a multi-directional linkage mechanism. Under the adjustment of this mechanism, the glass can be automatically centered, ensuring the relative position between glass and glass, glass and keel, realizing the composite process of centering adjustment, and improving the relative position dimensional accuracy of the insulating glass industry. At the same time, the equipment is simple and convenient to use. With the help of this equipment, ordinary workers can easily complete the composite operation of doors and windows;

[0020] 4. This equipment adopts self-locking cam transmission, which has simple structure, stable movement, synchronous action, ensuring the quality of assembly, simple structure, low manufacturing cost and easy adjustment;

[0021] 5. It has the function of secondary inspection of glass and keel errors. When the glass and keel are beyond the error range, the cam self-locking mechanism cannot work normally. The staff can judge that the error is large, which provides convenience for quickly checking the size of glass and keel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The accompanying drawings show a specific embodiment of the present invention.

[0030] The composite tooling of the hollow glass of the present invention comprises a rectangular frame 2, and a positioning device and a multi-directional linkage mechanism installed on the frame. A plurality of positioning devices are used. The positioning devices on the left and right sides of the frame are respectively connected to a first driving device and driven by the first driving device. The first driving device is also connected to the multi-directional linkage mechanism. The multi-directional linkage mechanism is connected to the positioning devices on the front and rear sides of the frame via a second driving device, thereby driving the movement of the positioning devices on the front and rear sides of the frame. The positioning device is used for positioning and aligning the outer edges of each layer of glass and the keel.

[0031] In the positioning device, one end of the connecting shaft 5 is sleeved with a reset spring 7, and the other end is fixedly connected to the positioning pad 3, which can contact the outer edges of the upper glass 17, the lower glass 18, and the keel 1 to position and align the layers of glass and the keel; the reset spring 7 is located inside the frame 2, and one end of the connecting shaft 5 is also located inside the frame and connected to the first drive device or the second drive device.

[0032] In the positioning device, the side of the positioning pad 3 contacting the keel 1 adopts a boss structure 21, the high part of the boss contacts the outer side of the keel, the low part of the boss contacts each layer of glass, and the height of the boss corresponds to the preset height difference between the keel and the glass.

[0033] In the positioning device, the positioning pad 3 is a nylon pad, and at least two connecting shafts are installed on one positioning pad; the starting end of the connecting shaft 5 is tightly inserted into the hole on the synchronization rod 12 to be fixedly connected with the synchronization rod, or the starting end of the connecting shaft is tightly inserted into the hole on the inclined block 8 to be fixedly connected with the inclined block, the end of the connecting shaft 5 has a screw hole, and the positioning pad has a pre-embedded stud 23, the stud is screwed into the screw hole of the connecting shaft to fix the connecting shaft and the positioning pad, and an adjustment gasket 24 can be placed between the end face of the connecting shaft and the positioning pad. (When necessary, add a gasket between the end face of the connecting shaft and the positioning pad, and when not necessary, do not add a gasket, and generally there is no gasket).

[0034] The first driving device of the positioning devices on the left and right sides of the frame adopts a self-locking cam transmission device; the second driving device of the positioning devices on the front and rear sides of the frame adopts a slide block adjustment device.

[0035] The slider adjustment device includes two inclined blocks 8 that contact each other through inclined surfaces, wherein inclined block 1 is fixedly connected to the connecting shaft 5 of the positioning device, and inclined block 2 is connected to the multi-directional linkage device; the multi-directional linkage device pushes inclined block 2 to move horizontally, thereby pushing inclined block 1 to move longitudinally toward the glass, so that the positioning device pushes the front or rear side of each layer of glass and the keel for positioning and alignment.

[0036] The self-locking cam transmission device includes a rotating shaft 13, a cam 14 fixed at one end of the rotating shaft, and a rotating handle 19 fixed at the other end of the rotating shaft. The rotating shaft is rotatably mounted on a frame 2, the rotating handle is located outside the frame, and the cam is located inside the frame. A self-locking plane 22 is provided on one side of the cam. When the cam rotates, its self-locking plane can contact the multi-directional linkage device and the positioning device, so that the positioning device pushes the left or right side of each layer of glass and the keel for positioning and alignment.

[0037] The multi-directional linkage device includes a synchronization rod 12 installed inside the frame, a screw rod 11 vertically connected to the end of the synchronization rod, the end of the screw rod is connected to the inclined block 8 in the slider adjustment device, and the cam 14 can contact the synchronization rod 12 when it rotates, thereby pushing the synchronization rod to move; a backing plate 9 is fixed to the outside of the frame through the support foot 10, and the backing plate is used to limit the position of the inclined block 8 in the front and rear directions; a guide rod 4 is fixed inside the frame, and a hole on the synchronization rod 12 is sleeved on the guide rod, so that the synchronization rod can move left and right along the guide rod.

[0038] In the multi-directional linkage device, one end of the screw rod 11 is screwed into the interior of the inclined block 2 8 through a thread, and the other end of the screw rod is threaded and inserted into the hole at the end of the synchronization rod 12. Nuts 16 are screwed on both sides of the screw rod on the synchronization rod. The synchronization rod is clamped by two nuts on the screw rod to limit the length of the screw rod inserted into the synchronization rod 12. The relative position of the synchronization rod and the inclined block 2 8 is adjusted by rotating the nut 16, and then the relative displacement of the inclined surface of the inclined block 2 and the inclined block 1 is adjusted, thereby adjusting the stroke of the positioning device in the front and rear directions.

[0039] A friction-resistant and noise-reducing sleeve 6 is fixed to the portion of the frame 2 that contacts the connecting shaft 5; a lifting handle 20 is installed on the upper surface of the frame or on the outer side of the frame.

[0040] A rotating handle 19 is also located on the upper surface of the frame.

[0041] The hollow window 15 is an area inside the composite tooling for placing the hollow glass.

[0042] The invention is a device suitable for the rapid compounding of insulating glass, which can quickly realize the rapid positioning and compounding of glass and keel, complete the centering adjustment, and meet the requirements of verticality and keeping the distance between the outer side of the glass and the outer side of the keel consistent during the compounding process of the insulating glass.

[0043] The present invention is a rapid composite tooling for windows on doors with double-glazed windows and keels, including five main parts: a frame integration, a positioning device, a slider adjustment device, a multi-directional linkage mechanism, and a self-locking cam transmission device. The positioning pad is made of nylon. The positioning device is divided into six groups, which are evenly distributed in the two width directions and two length directions of the frame in a one-to-two-two form. Each group of positioning devices is connected to the slider adjustment device, and the positioning process is completed during the adjustment process. The present invention designs a multi-directional linkage mechanism to realize the operation and control of the left slider adjustment device, the right slider adjustment device, and the side slider adjustment device through a node. The present invention designs a self-locking cam transmission mechanism, which can realize the self-locking function when the cam moves into place, and also has a limiting function.

[0044] When the specifications of insulating glass are changed (the difference in horizontal and vertical dimensions is less than or equal to 5 mm), the relative position of the positioning pads of the composite tooling needs to be adjusted. When adjusting the relative position of the positioning pads of the composite tooling, adjust the horizontal and vertical relative distances of the positioning pads of the composite tooling according to the external dimensions (horizontal dimension, vertical dimension) of the insulating glass to be used. By adjusting the depth of the screw-in stud of the connecting shaft, add or reduce gaskets between the end of the connecting shaft and the end face of the positioning pads, so that the spacing between the positioning pads on the left and right sides corresponds to the size of the glass in the left and right directions (horizontal dimension). By rotating the nut to adjust the position of the screw and the inclined block 2, adjust the position of the inclined block 1 and the positioning pads of the positioning devices on the front and rear sides, so that the spacing between the positioning pads on the front and rear sides corresponds to the size of the glass in the front and rear directions (longitudinal dimension).

[0045] The steps for compounding double-layer glass and keel are as follows:

[0046] Step 1: After wiping the lower glass clean, place it flat on the workbench. The operator pulls the auxiliary lifting handle to fit the composite tooling of the appropriate type (the positioning device is in a relaxed state) onto the lower glass.

[0047] Step 2: After the fitting is completed, rotate the rotary handles on both sides to make the positioning device of the tooling clamp the lower glass, the cam is self-locking, and the lower glass is positioned.

[0048] When the glass is not clamped after the cam self-locks or the glass is clamped before the cam completes the self-locking, it is because the glass has a large error. In this case, it is necessary to first check whether the size error of the glass is within the usable range. If the error is too large and is not within the usable range, this piece of glass will not be used. If the error is within the usable range, the insertion depth of the screw in the synchronization rod can be adjusted by adjusting the connecting nut 16 between the screw 11 and the synchronization rod 12, thereby adjusting the relative position of the positioning pad in the length direction (front and back direction, longitudinal direction); by (adding or reducing the gasket between the connecting shaft and the positioning pad) to adjust the width direction (left and right direction, horizontal direction), adjust the relative position of the positioning pad in the width direction to ensure assembly accuracy.

[0049] Step 3: Stick special double-sided tape on the upper and lower sides of the keel's contact surface with the glass, place the keel in the composite tooling, and place the keel on the lower layer of glass. At the same time, complete the relative positioning of the glass and the edge of the keel (the upper and lower sides of the positioning pad are chamfered, and the edges of the keel and glass are also chamfered to facilitate the placement of the keel and the upper layer of glass).

[0050] Step 4: Place the upper glass in the composite tooling, and place the upper glass on the keel. At the same time, complete the relative positioning of the upper glass and the lower glass, and the upper glass and the keel.

[0051] Step 5: Pull off the protective film of the special double-sided tape on the keel, press the insulating glass, make the glass and the glass, and the glass and the keel firmly bonded, lock the relative position, and ensure that the relative position will not change after the tooling is removed.

[0052] Step 6: Rotate the small handle in the opposite direction, the cam self-locks in the opposite direction, and the positioning device returns to its original position under the action of the reset spring. The operator removes the tooling by pulling the auxiliary lifting handle, and the compounding is completed.

[0053] After the fifth step is completed, the composite tooling can also be clamped on the insulating glass all the time, and the composite tooling and the insulating glass can be placed upright together, and multiple insulating glasses are roughly parallel and close together, saving floor space, and the nylon pads of the composite tooling can relieve the stress of the insulating glass in the vertical direction to prevent the insulating glass from bursting. Before the insulating glass is to be installed on the building, the composite tooling can be loosened and removed, and the composite tooling can continue to be used for other insulating glass composite work.

[0054] Different types of composite tooling can be made according to the different sizes of insulating glass. Composite tooling suitable for insulating glass with three layers of glass can also be made according to the same principle.
