Description

Technical Field

[0001] This invention belongs to the field of bonding tooling, specifically relating to a crystal bonding tooling with suction cups and its usage method. Background Technology

[0002] As a tool used to assist industrial production by performing bonding operations during the manufacturing process, bonding fixtures currently have relatively fixed upper and lower mold positions. Regularly shaped parts or parts with positioning structures can be positioned by contouring using conventional bonding fixtures to achieve bonding of the parts.

[0003] For the irregularly shaped crystals and their supports on existing automotive gear shift levers, the crystals include precision-machined surfaces and bonding surfaces. Due to limitations in crystal processing technology, the contours of the two beveled surfaces on the bonding surface fluctuate significantly, and there is no positioning structure between the crystals and the crystal supports. Therefore, even if the conventional bonding tooling has high processing precision, the different processing errors between different crystals can lead to surface differences or even uneven gaps in the bonded products, resulting in a low yield rate. If the bonding is poor, the rework cost is extremely high, and it may even lead to the scrapping of some products. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a crystal bonding fixture with suction cups and its usage method, which solves the problem of surface differences or even uneven gaps in different crystal bonding products caused by the contour fluctuation differences of different irregular crystal bonding inclined surfaces.

[0005] The objective of this invention can be achieved by adopting the following technical solution: a crystal bonding fixture with suction cups, comprising a fixture mold frame, a connecting base plate, and a connecting top plate. The connecting base plate and the connecting top plate move relative to each other to control the bonding of the crystal support and the crystal. The fixture mold frame is fixedly connected to the connecting base plate. It also includes an upper suction component, a lower suction component, and a control device. The connecting base plate is provided with a lower fixture mold for placing the crystal. The lower fixture mold can slide on the connecting base plate. Below the connecting top plate is a upper fixture mold for fixing the crystal support. The upper suction component passes through the upper fixture mold to the surface of the crystal support. The lower suction component passes through the connecting base plate to the bottom surface of the lower fixture mold. The control device controls the adsorption or release of the upper suction component and the lower suction component respectively.

[0006] By adopting the above technical solution, the upper adsorption component makes the bonding process in the crystal holder more stable, avoiding the bonding effect caused by the shaking of the crystal holder. Furthermore, the adsorption of the lower adsorption component on the lower mold of the tooling can be adjusted by a control device, which facilitates the switching between locking or floating of the lower mold of the tooling. Furthermore, the lower mold of the tooling is provided with a contour groove that corresponds to the precise surface structure of the crystal, making the crystal placement more stable. The lower mold of the tooling can slide relative to the connecting base plate, so that the lower mold of the tooling can move and adjust the position of the crystal on the plane, making the relative position between the crystal and the crystal holder more accurate, and preventing the problem of poor bonding surface caused by different processing errors of the bonding surfaces of different crystals.

[0007] In a further embodiment of the present invention, the connecting base plate is provided with a countersunk hole and has an overall concave structure, the lower die of the tooling is located in the countersunk hole of the connecting base plate, and a plurality of buffer components are provided between the lower die of the tooling and the connecting base plate.

[0008] With the above technical solution, buffers can be provided on both sides of the lower die of the tooling to limit the sliding range of the lower die of the tooling. When the lower die of the tooling slides too fast, it provides a buffering effect to reduce the impact of vibration caused by operational errors on the crystal. The structure is simple and easy to install.

[0009] In a further embodiment of the present invention, the upper adsorption component and the lower adsorption component are respectively connected to a connecting valve. The two connecting valves can be fixedly connected to the connecting top plate and the tooling mold frame respectively by setting connecting parts. The upper mold of the tooling is detachably connected to the connecting top plate. Each connecting valve is connected to the control device.

[0010] By adopting the above technical solution, the connecting valve is set to enable the control device to draw or blow air onto the upper and lower adsorption components, thereby achieving the function of adsorbing or releasing the upper and lower adsorption components. It is fixedly connected to the connecting top plate and the tooling mold frame respectively, and can move with the pressing or lifting of the connecting top plate, so that the crystal bracket and the connecting upper mold are always in a relatively static state before bonding, avoiding bonding errors caused by displacement of the crystal bracket on the connecting upper mold. Furthermore, the tooling upper mold can be disassembled and replaced, avoiding the impact of wear on the tooling upper mold on the positioning accuracy of the crystal bracket.

[0011] In a further embodiment of the present invention, a universal joint is provided between the upper adsorption member and the connecting valve in which they communicate.

[0012] Using the above technical solution, the universal joint can drive the upper adsorption component to rotate freely, ensuring that the adsorption surface of the upper adsorption component can contact the surface to be adsorbed at different angles, and preventing the inclined surface from being accurately adsorbed due to processing errors of the surface to be adsorbed.

[0013] In a further embodiment of the present invention, the upper die of the tooling includes an upper die fixing seat and several plug-ins, and the upper die of the tooling has a through hole for the connecting valve to pass through.

[0014] Using the above technical solution, each of the plug-ins can be inserted into the mounting slot provided on the crystal bracket. The through hole can be provided on the upper mold fixing seat or on the plug-in, so that the connecting valve and the upper adsorption component can adsorb and fix the crystal bracket through the through hole.

[0015] In a further embodiment of the present invention, the upper mold of the tooling is provided with a plurality of clamping spaces for fixing the crystal bracket, and the width of each clamping space is wider than the wall thickness of the crystal bracket mounting groove.

[0016] Using the above technical solution, the groove wall of the crystal bracket's mounting slot can be inserted into the clamping space, thereby playing a role in avoiding collisions. The height of the clamping space can be set according to the height of the groove wall of the crystal bracket's mounting slot, so that after each groove wall of the crystal bracket's mounting slot is inserted to the bottom, the angle of the crystal bracket's mounting surface is corrected and determined, thereby achieving the positioning of the crystal bracket.

[0017] In a further embodiment of the present invention, each clamping space has a plurality of protrusions on its sidewall to increase the upper limit of the friction force between the sidewall of the clamping space and the crystal holder.

[0018] By adopting the above technical solution, various protrusions are set to squeeze the groove wall of the crystal holder, thereby achieving the positioning and initial fixation of the crystal holder. Furthermore, by reducing the width of the clamping space, the contact area between the side wall of the clamping space and the crystal holder is increased, thereby increasing the upper limit of the friction between the side wall of the clamping space and the crystal holder, resulting in tighter clamping. This ensures that the crystal holder will not fall off the tooling mold due to its own weight, making it more stable.

[0019] In a further embodiment of the present invention, a heightening seat is fixedly provided on the connecting base plate, and the heightening seat is provided with a hinge for realizing relative rotation between the connecting base plate and the connecting top plate.

[0020] By adopting the above technical solution, the height difference between the connecting bottom plate and the connecting top plate is controlled by setting the height-adjusting seat, and the pressing action is achieved by flipping the hinge cover and lifting the connecting top plate to achieve the fitting action. The operation is simple and the installation is convenient.

[0021] In a further embodiment of the present invention, both the upper adsorption member and the lower adsorption member are suction cups, and the suction cup includes a flexible suction cup and an air intake located in the middle of the suction cup.

[0022] By adopting the above technical solution, the contact between the flexible suction cup and the crystal bracket and the lower mold of the tooling can prevent hard collisions, thereby better protecting the crystal bracket and the lower mold of the tooling.

[0023] In a further embodiment of the present invention, the control device is fixedly disposed within the tooling mold frame.

[0024] By adopting the above technical solution, the tooling mold frame can support and protect the control device and save space. The control device can be a pneumatic device and can be connected to the air inlet through a gas connection device such as an air pipe. The suction cup can be adsorbed or released by suction or blowing air. The air inlet is located in the middle of the suction cup to make it more effective when used. Furthermore, the control switch of the control device can be set on the surface of the tooling mold frame to make the control operation of the pneumatic device more convenient.

[0025] Another objective of this invention is to provide a method for using a crystal bonding fixture with suction cups, including installation, pre-pressing, adaptive adjustment, bonding, and detachment, with the specific steps as follows: S1: Installation: Install the crystal bracket on the upper mold of the tooling, adjust the control device to make the upper adsorption component adsorb onto the top surface of the crystal bracket to fix the crystal bracket, and place the crystal with adhesive film into the contour groove of the lower mold of the tooling so that the bottom surface of the crystal is in contact with all surfaces of the contour groove of the lower mold of the tooling. S2: Pre-press: Adjust the control device to release the lower adsorption component from the lower mold of the tooling and press the connecting top plate together; S3: Adaptive adjustment: After pre-pressing, the two inclined surfaces of the crystal bonding surface are subjected to pressure and transmitted to the lower mold of the tooling. The lower mold of the tooling moves on the connecting base plate under pressure, adaptively correcting the error between the crystal support and the crystal, so that the gap between the crystal support and the crystal is within the standard range, and controlling the control device to make the lower adsorption component adsorb the lower mold of the tooling. S4: Fitting: Lift the connecting top plate to move the crystal bracket away from the crystal, peel off the adhesive film on the surface of the crystal, and then press the connecting top plate again to fit the crystal bracket with the crystal. S5: Detachment: Adjust the control device to release the lower suction component from the crystal support, lift the connecting top plate, and detach the crystal support from the upper mold of the tooling, so that the finished product can be taken out from the lower mold of the tooling.

[0026] By adopting the above technical solution, the positioning problem of irregular crystal bonding is solved. Through pre-pressing, the bonding error between the crystal and the crystal holder can be initially determined, thereby adjusting the position of the lower mold of the tooling to avoid excessive difference after bonding. Furthermore, the upper and lower suction components fix the crystal holder and the lower mold of the tooling relatively. During the pressing process, the crystal and the crystal holder will not shift in the horizontal direction, thus ensuring the fit between the crystal and the holder and ensuring the reliability of the difference and gap after bonding.

[0029] The embodiments of the technical solution of the present invention will be described in detail below. These embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore merely examples, and should not be used to limit the scope of protection of the present invention.

[0030] The crystal bonding fixture with suction cup of the present invention is a new type of fixture optimized based on conventional bonding fixtures and combined with the actual product functional requirements. It solves the positioning problem of bonding irregular crystals, avoids bonding surface defects caused by large fluctuations in crystal contours, improves product yield, and reduces manufacturing costs.

[0031] This invention discloses a crystal bonding fixture with suction cups and a method for using it. In an embodiment of this invention, a crystal bonding fixture with suction cups is provided, such as... Figures 1-4 As shown, it includes a tooling mold frame 1, a connecting base plate 2, and a connecting top plate 3. The tooling mold frame 1 is fixedly connected to the connecting base plate 2, and the connecting base plate 2 and the connecting top plate 3 can move relative to each other to control the bonding action between the crystal bracket and the crystal.

[0032] In this embodiment, a heightening seat 11 is fixedly installed on the connecting base plate 2, and a hinge 12 is provided on the heightening seat 11. The two ends of the hinge 12 are fixedly connected to the heightening seat 11 and the connecting top plate 3 respectively, thereby realizing the relative rotation of the connecting base plate 2 and the connecting top plate 3. The tooling can be pressed and lifted by the operation of the flip cover. The operation is simple and the installation is convenient.

[0033] This embodiment also includes an upper adsorption component 6, a lower adsorption component 7, and a control device 8. A lower tooling mold 4 is provided on the connecting base plate 2. The lower tooling mold 4 is provided with a contour groove. The contour groove matches the precise processing surface structure of the crystal and can be used to accurately and stably place the crystal. The lower tooling mold 4 has four elliptical slots. Bolts can be set to fix the lower tooling mold 4 to the connecting base plate 2. After slightly loosening the bolts, the lower tooling mold 4 can slide on the connecting base plate 2.

[0034] An upper mold 5 is provided between the top plate 3 and the lower mold 4. The upper mold 5 includes a plug for engaging with the mounting slot on the crystal bracket. After aligning the mounting slot of the crystal bracket with the plug of the upper mold 5, pressing it down will achieve the positioning and initial fixation of the crystal bracket.

[0035] like Figure 5 As shown, the lower suction component 7 passes through the connecting base plate 2 and contacts the bottom surface of the lower mold 4 of the tooling, while the upper suction component 6 passes through the upper mold 5 of the tooling and contacts the surface of the crystal support. Both the upper suction component 6 and the lower suction component 7 are suction cups. The suction cup includes a flexible suction cup and an air intake located in the middle of the suction cup. The air intake located in the middle of the suction cup can make it more effective when in use.

[0036] Each of the upper adsorption component 6 and the lower adsorption component 7 has a connecting valve 9 connected to its air outlet. The connecting valve 9 connected to the upper adsorption component 6 is fixedly connected to the connecting top plate 3. The control device 8 can be a pneumatic device and is connected to the two connecting valves 9 through a gas connection device such as an air pipe. The adsorption or release of the two suction cups is achieved by suction or blowing air. Therefore, the control device 8 can control the upper adsorption component 6 to adsorb or release on the surface of the crystal support and can control the lower adsorption component 7 to adsorb or release on the bottom surface of the tooling lower mold 4.

[0037] A universal joint 13 is provided between the upper adsorption component 6 and the connecting valve 9. The universal joint can drive the upper adsorption component 6 to rotate freely, ensuring that the adsorption surface of the upper adsorption component 6 can contact the surface to be adsorbed at different angles, and preventing the slope surface from being accurately adsorbed due to the processing error of the surface to be adsorbed.

[0038] In this embodiment, the upper die 5 includes an upper die fixing base 51 and three inserts 52, such as... Figure 8 As shown, the shape of each plug-in 52 is the same as the shape of the mounting groove structure set on the crystal bracket. The plug-in 52 can be inserted into the mounting groove of the crystal bracket to achieve the positioning of the crystal bracket. There are two clamping spaces 14 between the upper mold fixing seat 51 and the three plug-ins 52. The two clamping spaces 14 are used to clamp the two groove walls of the crystal bracket respectively, so that the crystal bracket is subjected to a certain friction force to prevent it from falling off, thereby achieving the initial fixation of the crystal bracket on the upper mold 5 of the tooling. The clamping space 14 is slightly wider than the groove wall thickness of the crystal bracket mounting groove. After the fitting is completed, when the connecting top plate 3 drives the upper mold 5 of the tooling to rotate, the width of the clamping space 14 is wide enough to ensure that the upper mold 5 of the tooling does not contact or collide with the groove wall of the crystal bracket mounting groove.

[0039] In this embodiment, as Figure 8 As shown, each plug 52 has protrusions evenly distributed on its sidewall. The protrusions can be strip-shaped or block-shaped. This makes the width of the two clamping spaces 14 formed on the upper mold 5 of the tooling slightly smaller than the width of the non-protruding parts. This increases the contact area between the groove wall of the crystal holder and the sidewall of the clamping space 14, thereby increasing the upper limit of friction and making the clamping of the crystal holder more stable. However, the upper limit of friction is less than the force required to separate the crystal from the crystal holder after the bonding is completed, thus preventing the finished product from being unable to detach.

[0040] The upper mold 5 of the tooling has a through hole 53 for the connecting valve 9 to pass through. The upper adsorption component 6 passes through the through hole on the upper mold 5 of the tooling and contacts the surface of the crystal support. The through hole can also be located on the plug-in 52, as long as the upper adsorption component 6 and the connecting valve 9 can pass through. The connecting base plate 2 also has a through hole to allow the lower adsorption component 7 and the connecting valve 9 to pass through.

[0041] The upper die 5 and the connecting top plate 3 are detachably connected by bolts. The movement of the upper die 5 can be controlled by operating the connecting top plate 3. At the same time, the upper die can be disassembled and replaced to avoid the wear of the upper die affecting the positioning accuracy of the crystal bracket. The connecting valve 9 is detachably connected to the connecting top plate 3 or the die frame 1 by bolts. The control device 8 can be fixedly installed in the die frame 1. The die frame can support and protect the control device and save space.

[0042] In this embodiment, as Figures 6-7 As shown, the connecting base plate 2 has a countersunk hole and an overall concave structure. The lower die 4 is located in the countersunk hole of the connecting base plate 2. Two buffers 10 are provided between each surface of the lower die 4 and the connecting base plate 2. The buffers 10 can be springs.

[0043] The buffer 10 can limit the sliding stroke of the lower die 4 on the horizontal plane, preventing the lower die 4 from colliding with the connecting base plate 2 and causing damage. It also provides a buffering effect when the lower die slides too fast, reducing the impact of vibration caused by operational errors on the crystal. The structure is simple and easy to install.

[0044] A method for using a crystal bonding fixture with suction cups includes the following steps: installation, pre-pressing, self-adjustment, bonding, and detachment. Step 1: Installation: Connect the crystal holder to the upper mold 5 of the tooling to achieve the positioning of the crystal holder. Then adjust the control device 8 to make the upper adsorption part 6 adsorb onto the top surface of the crystal holder to fix the crystal holder. At the same time, place the crystal with adhesive film into the contour groove of the lower mold 4 of the tooling so that the finished surface of the crystal is in contact with all surfaces of the contour groove of the lower mold 4 of the tooling. Step 2: Pre-pressing: Slightly loosen the bolts between the lower mold 4 and the connecting base plate 2, adjust the control device 8 to release the suction of the lower adsorption component 7 on the lower mold 4, and then press the connecting top plate 3 to make the crystal bracket contact the crystal with the adhesive film. Step 3: Adaptive Adjustment: Due to the pre-pressure in Step 2, one of the inclined surfaces of the crystal bonding surface is subjected to pressure, which is transmitted to the lower mold 4 of the tooling. The lower mold 4 moves on the connecting base plate 2 under the pressure perpendicular to the inclined surface of the crystal bonding surface until the inclined pressure disappears or is balanced with the pressure of another inclined surface, and then stops. This realizes the automatic correction of the deviation between the crystal support and the crystal, and ensures that the gap of the bonding surface is within the standard range. Then, the control device 8 is controlled to make the lower adsorption component 7 adsorb the lower mold 4 of the tooling to fix the lower adsorption component 7, complete the positioning of the tooling base plate, and thus realize the positioning of the crystal. Step 4: Bonding: Lift the connecting top plate 3 to move the crystal holder away from the crystal, peel off the adhesive film on the surface of the crystal, and then rotate the connecting top plate 3 again to press it together so that the crystal holder comes into contact with the crystal to complete the bonding. Step 5: Detachment: such as Figure 4 As shown, the adjustment and control device 8 releases the lower adsorption component from the crystal support, lifts the connecting top plate 3, and realizes the separation of the crystal support from the upper mold 5 of the tooling, so that the finished product can be taken out from the lower mold 4 of the tooling.

[0045] After the tooling is used, the bolts fixing the lower mold 4 of the tooling and the connecting base plate 2 can be tightened again to avoid the risk of the lower mold 4 of the tooling sliding randomly on the connecting base plate 2 and causing collisions.

[0046] The above description is merely a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
