Description

Technical Field

[0001] The utility model relates to the technical field of glass production devices, in particular to a glue injection device for laminated glass. Background Technique

[0002] Due to its excellent light transmittance, glass materials are widely used in various buildings. However, after glass breaks, relatively sharp glass fragments will be generated, which are easy to cause damage to the human body. Later, laminated glass gradually emerged. Even if laminated glass breaks, the fragments will be stuck on the glue layer, and the surface of the broken glass still remains clean and smooth. This effectively prevents the occurrence of events such as fragments stabbing and penetrating and falling, ensuring personal safety.

[0003] The Chinese utility model patent, with the application number 201520156372.3 and the patent name of a laminated glass production device, discloses a support seat, including a glue sealing seat, a first glass fixing block, a second glass fixing block, a sealing cover, a vacuum pump, a bracket, a glass glue storage cylinder, a liquid pump, a conveying cylinder, a transmission rod, a corrugated pipe, and a glue nozzle. Compared with the prior art, this laminated glass production device has a simple structure and powerful functions. It can effectively avoid the generation of bubbles when injecting glue between two glasses, improve product quality, and prevent scrapping due to poor quality.

[0004] However, in the above technical solution, it is only suitable for injecting glue into glass with a fixed thickness. When injecting glue from top to bottom, due to the action of gravity, the glue injection is uneven, and there is a defect that the clamping force cannot be effectively adjusted. Summary of the Invention

[0005] The purpose of the utility model is to provide a glue injection device for laminated glass to solve the problems raised in the above background technique. The utility model has the advantages of automatic clamping, fast and uniform glue injection, and fast dry glue after glue injection.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A glue injection device for laminated glass, including a support seat, a support frame is provided on the support seat, a glue sealing bottom plate is provided inside the support frame, and a glue injection assembly is provided below the support seat to achieve efficient glue injection and save raw material use. Due to the optimized design of the glue injection position, the glue can be injected more accurately. Above the glue sealing bottom plate, a clamping assembly is provided. By setting the glue sealing bottom plate and the clamping assembly, the glue injection accuracy and stability of the laminated glass are effectively improved. During the glue injection process, the clamping assembly can ensure that the glass is fixed and does not shift, thus significantly improving the quality of the product and reducing the problem of uneven glue injection caused by displacement.

[0007] Above the clamping assembly is provided with a cover. On the top of the cover is provided with a lifting mechanism. The cover is provided with a ventilation hole, and a vacuum tube is inserted through the ventilation hole. One end of the vacuum tube is flush with the inner wall of the cover. An electric valve is provided on the vacuum tube. The other end of the vacuum tube is connected to a vacuum pump. By setting the vacuum tube and the vacuum pump, it is realized to timely remove air bubbles during the glue injection process, ensuring the uniformity of the glue layer.

[0008] The clamping assembly includes a first clamping block and a second clamping block arranged in parallel with each other. Between the first clamping block and the second clamping block and the side walls of the corresponding support frames on both sides are provided with a pushing assembly. On the opposite surfaces of the first clamping block and the second clamping block are provided adsorption surfaces for adsorbing glass.

[0009] As a further scheme of the present utility model, heaters are provided inside the first clamping block and the second clamping block, and the heaters are electric heating wire heaters. The heaters heat in both directions, eliminating the problems of low heating efficiency and uneven heat reception, making the glass heat more evenly, and greatly reducing defects such as glass warping.

[0010] As a further scheme of the present utility model, the glue injection assembly includes a pressure glue injection tank. On the top of the pressure glue injection tank is provided a glue injection pipe, and the glue injection pipe sequentially passes through the support seat and the glue sealing bottom plate and is arranged at the central position of the glue sealing bottom plate.

[0011] As a further scheme of the present utility model, the port of the vacuum tube flush with the inner wall of the cover is arranged on the central axis of the cover, and the vacuum tube is a flexible tube of sufficient length.

[0012] As a further scheme of the present utility model, the lifting mechanism includes a lifting motor, the shaft end of the lifting motor is vertically downward, and the shaft end of the lifting motor is connected to the center of the top surface of the cover.

[0013] As a further scheme of the present utility model, the pushing assembly includes a pushing motor, and the output shaft ends of the pushing motor are respectively connected to the first clamping block and the second clamping block. The pushing motor respectively pushes the first clamping block and the second clamping block to move towards each other or separate. The pushing assembly enables the clamping force to be adjustable, can adapt to glass of different thicknesses and sizes, and enhances the applicability and flexibility of the device.

[0014] As a further scheme of the present utility model, the adsorption surfaces are adsorption rubber surfaces respectively attached to the surfaces of the first clamping block and the second clamping block. The adsorption rubber surfaces can firmly adsorb the glass, avoiding glass damage that may be caused by traditional mechanical clamping.

[0015] As a further solution of the present utility model, a right-angled groove is provided on the sealing surface of the cover. The groove width of the right-angled groove just accommodates the space of the first clamping block, the second clamping block and the two pieces of glass clamped therein. Since the groove width of the right-angled groove just accommodates the clamping blocks and the glass, the stability and centering of the glass during the assembly process are ensured, the sealing performance of the cover is effectively improved, and the leakage problem caused by poor sealing in the traditional technology is avoided.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: By setting the sealant bottom plate and the clamping assembly, the glue injection accuracy and stability of the laminated glass are improved. The clamping assembly can ensure that the glass is fixed without displacement, reducing the problem of uneven glue injection caused by displacement. The glue injection assembly arranged under the support seat can achieve efficient glue injection, and the glue can be more accurately injected into the interlayer. The design of the lifting mechanism and the ventilation holes on the cover, through the setting of the vacuum tube and the vacuum pump, enables the device to form a vacuum environment during the glue injection process, timely remove air bubbles, and the glue injection is uniform. The heating component has high heating efficiency and uniform heat absorption, and can quickly dry the glue injection. The pushing component between the clamping assembly and the side wall of the support frame makes the clamping force adjustable, can adapt to glasses of different thicknesses and sizes, and enhances the applicability and flexibility of the device.

Inside the support frame, there is a glue - sealing bottom plate 2. On the upper surface of the glue - sealing bottom plate, there is a sealing damping pad 201 to seal the glue - injecting cavity and form a closed space for effective glue injection.

[0023] Below the support base, there is a glue - injecting component. The glue - injecting component includes a pressure glue - injecting tank 1. The pressure glue - injecting tank is filled with glass glue. At the top of the pressure glue - injecting tank, there is a glue - injecting pipe 101. The glue - injecting pipe passes through the support base and the glue - sealing bottom plate in sequence, and the glue - injecting pipe is arranged at the center position of the glue - sealing bottom plate.

[0024] Above the glue - sealing bottom plate, there is a clamping component 4. The clamping component includes a first clamping block 402 and a second clamping block 403 which are arranged in parallel. Between the first clamping block and the second clamping block and the side walls of the corresponding support frame on each side, there is a pushing component. The pushing component includes a pushing motor 401. The output shaft ends of the pushing motor are respectively connected to the first clamping block and the second clamping block. The pushing motor respectively pushes the first clamping block and the second clamping block to move towards each other or separate.

[0025] On the opposite surfaces of the first clamping block and the second clamping block, there is an adsorption surface 9 for adsorbing glass. The adsorption surface is an adsorption rubber surface respectively attached to the surfaces of the first clamping block and the second clamping block.

[0026] Place the glasses between the first clamping block and the second clamping block respectively. One glass is attached to the adsorption rubber surface of the corresponding first clamping block, and the other glass is attached to the adsorption rubber surface of the corresponding second clamping block. Start the pushing motor, and at the same time, push the first clamping block and the second clamping block to move towards each other until a glue - injecting space is formed between the two glasses, then turn off the pushing motor.

[0027] Above the clamping component, there is a cover 6. On the sealing surface of the cover, there is a right - angled groove. The groove width of the right - angled groove just accommodates the space of the first clamping block, the second clamping block and the two glasses clamped therein.

[0028] At the top of the cover, there is a lifting mechanism. The lifting mechanism includes a lifting motor 7. The shaft end of the lifting motor is vertically downward, and the shaft end of the lifting motor is connected to the center of the top surface of the cover.

[0029] The initial position of the lifting mechanism is that the shaft end of the lifting motor is in a retracted state, driving the cover to be in a separated state from the first clamping block and the second clamping block of the clamping component.

[0034] The first clamping block and the second clamping block are internally provided with heaters, and the heaters are electric heating wire heaters. After the heaters are powered on, the electric heating wires heat up and transfer the heat to the glass glue between the two pieces of glass to effectively dry the glass glue.
