Description

Technical Field

[0001] The present invention relates to the field of automated machinery, and particularly to a combined glue filling machine and a glue filling method. Background Art

[0002] Existing glue filling machines are generally vacuum glue filling machines and atmospheric pressure glue filling machines. When using an atmospheric pressure glue filling machine, glue is filled into a product under atmospheric pressure, and then air bubbles in the glue are discharged by means of vacuum holding pressure, resulting in an extended production cycle and reduced efficiency. When directly filling glue through a vacuum glue filling machine, first, the environment needs to be evacuated, then glue is injected and pressure is maintained. Each time the chamber is opened, vacuum pumping needs to be repeated, causing greater energy consumption. Moreover, the time required for filling glue in the product is longer than the product loading time. After the product loading is completed, it can only wait for the subsequent processes to be completed, and the working efficiency is also relatively low. Summary of the Invention

[0003] The main object of the present invention is to provide a combined glue filling machine and a glue filling method, which realizes the adjustment of the glue filling amount between two stations by combining a vacuum glue filling machine and an atmospheric pressure glue filling machine, so as to improve the glue filling efficiency.

[0004] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0005] A combined glue filling machine includes an atmospheric pressure glue filling device, a first vacuum holding pressure device, a second vacuum holding pressure device, and a vacuum glue filling device. Feed ports and discharge ports are respectively provided on both sides of the atmospheric pressure glue filling device. The discharge port is connected to the inlet of the first vacuum holding pressure device. A vacuum glue filling device is provided on the discharge port side of the first vacuum holding pressure device. A second vacuum holding pressure device is provided on the discharge port side of the vacuum glue filling device. Independent sealed opening and closing doors are provided between the atmospheric pressure glue filling device, the first vacuum holding pressure device, the second vacuum holding pressure device, and the vacuum glue filling device, as well as at the discharge port of the second vacuum holding pressure device. When the sealed opening and closing doors are closed, the internal spaces of the first vacuum holding pressure device, the vacuum glue filling device, and the second vacuum holding pressure device are all in a sealed state. The first vacuum holding pressure device, the second vacuum holding pressure device, and the vacuum glue filling device are all independently connected to a vacuum pump. The atmospheric pressure glue filling device performs pre-glue filling of the product, and the amount of pre-glue filling is only a part of the required glue filling amount of the product, that is, incomplete glue filling is completed. Then, the first vacuum holding pressure device between the atmospheric pressure glue filling device and the vacuum glue filling device evacuates and holds pressure to remove air bubbles in the glue. Then, secondary glue filling is performed through the vacuum glue filling device to complete the glue filling of the product.

[0006] Further, a product preheating device is connected to the feed port of the atmospheric pressure glue filling device, and a glue curing device is connected to the discharge port of the second vacuum holding pressure device.

[0007] Further, a first transfer device is fixedly installed in the chambers of the atmospheric pressure glue filling device and the vacuum glue filling device, and a second transfer device is fixedly installed in the chambers of the first vacuum pressure maintaining device and the second vacuum pressure maintaining device.

[0008] Further, the first transfer device includes a first fixing frame, a first transfer conveyor and a positioning and adjusting device. The first transfer conveyor is fixedly installed at the upper end of the first fixing frame, and the positioning and adjusting device is fixedly connected to the lower end of the first fixing frame. The positioning and adjusting device is fixedly installed on the atmospheric pressure glue filling device or the vacuum glue filling device. First limit components and second limit components are respectively arranged at the front and rear ends of the first transfer conveyor, and the first limit components and the second limit components are fixedly installed on the first fixing frame.

[0009] Further, the second transfer device includes a second fixing frame, a second transfer conveyor, a second front end limiting device and a second rear end limiting device. The second transfer conveyor is fixedly installed on the second fixing frame. A second rear end limiting device is arranged at the feeding end of the second transfer conveyor, and a second front end limiting device is arranged at the discharging end of the second transfer conveyor.

[0010] Further, the positioning and adjusting device includes a lifting module, a yawing module and a telescopic module. The yawing module is connected to the lifting module, and the telescopic module is connected to the yawing module. The telescopic module can slide towards the adjacent station and extend to the discharging end or the feeding end of the second transfer device at the adjacent station.

[0011] Further, a glue filling method for a combined glue filling machine includes pre-glue filling of products through the atmospheric pressure glue filling device. The glue filling amount of the pre-glue filling is only a part of the required glue filling amount of the products, that is, incomplete glue filling is completed. Then, the first vacuum pressure maintaining device between the atmospheric pressure glue filling device and the vacuum glue filling device evacuates the air and maintains the pressure to remove the bubbles in the glue. Then, secondary glue filling is carried out through the vacuum glue filling device to complete the glue filling of the products. By dividing the glue filling method into two steps, the total glue filling time is shortened, and the glue filling efficiency is improved on the premise of ensuring the glue filling quality.

[0012] Further, the specific steps of glue filling include:

[0013] S1 Preheating: Load the products onto the fixtures, and transfer the fixtures with the products to the preheating device for preheating before glue filling of the products. Then, convey the preheated products and fixtures to the designated position through the conveyor belt;

[0014] S2 The first transfer: Connect the first transfer device in the atmospheric pressure glue filling device with the conveyor belt in the preheating device. Pick up the product and the fixture from the conveyor belt in the preheating device that has sent out the fixture and the product, and adjust the positions of the fixture and the product through the positioning and adjusting device so that the product is at the glue filling position. Clamp the product or the fixture with the clamping components on both sides of the first transfer conveyor device to prevent the product from moving.

[0015] S3 Atmospheric pressure glue filling: Insert the glue filling device installed above the atmospheric pressure glue filling device into the product to perform the first step of glue filling on the product.

[0016] S4 The second transfer: Transfer the fixture and the product in the atmospheric pressure glue filling device to the first vacuum pressure maintaining device through the first transfer device to move the product and the fixture into the first vacuum pressure maintaining device. After the transfer is completed, retract the first transfer device of the atmospheric pressure glue filling device, and perform the subsequent transfer of the product from the preheating device to the atmospheric pressure glue filling device, that is, repeat S2.

[0017] S5 The first pressure maintaining: Start the sealed opening and closing door fixedly installed on the first vacuum pressure maintaining device to make the internal space of the first vacuum pressure maintaining device form a sealed state, and perform vacuum pumping through the connected vacuum pump. At this time, the vacuum glue filling device and the second vacuum pressure maintaining device perform vacuum pumping simultaneously.

[0018] S6 The third transfer: Transfer the product and the fixture that have completed vacuum pressure maintaining in the first vacuum pressure maintaining device through the first transfer device in the vacuum glue filling device. The transfer method is the same as that of the first transfer device of the atmospheric pressure glue filling device. After the product is transferred, close the sealed opening and closing door. The first vacuum pressure maintaining device repeats S4 and S5.

[0019] S7 Vacuum glue filling: The vacuum glue filling device completes all the glue filling work. Open the sealed opening and closing door between the vacuum glue filling device and the second vacuum pressure maintaining device to connect the inner cavities of the vacuum glue filling device and the second vacuum pressure maintaining device. After transferring the product to the second vacuum pressure maintaining device through the first transfer device inside the vacuum glue filling device, close the sealed opening and closing door between the vacuum glue filling device and the second vacuum pressure maintaining device. The second vacuum pressure maintaining device performs vacuum pressure maintaining. After the pressure maintaining is completed, open the sealed opening and closing door at its discharge end to transfer the product to the curing device for curing the glue inside the product. After the product and the fixture are transferred out of the second vacuum pressure maintaining device, close the sealed opening and closing door at its discharge end and perform vacuum pumping again.

[0020] Further, the glue filling time of the atmospheric pressure glue filling in step S3 is the pressure maintaining time of the first vacuum pressure maintaining device or the glue filling time of the vacuum glue filling device.

[0021] Furthermore, the vacuum pumping time of the first vacuum pressure maintaining device and the time when the product completes pressure maintaining in step S5 are the same as the glue injection time of the vacuum glue filling device.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] The present invention realizes the adjustment of the glue filling amount between two stations by combining a vacuum glue filling machine and an atmospheric pressure glue filling machine, thereby improving the glue filling efficiency.

[0024] The glue filling amounts of the vacuum glue filling device and the atmospheric pressure glue filling device of the present invention can be adjusted according to the size of the product, so as to minimize the glue filling time. BRIEF DESCRIPTION OF THE DRAWINGS

When the sealed opening and closing doors 5 are closed, the internal spaces of the first vacuum pressure maintaining device 2, the vacuum glue filling device 4, and the second vacuum pressure maintaining device 3 are all in a sealed state. The first vacuum pressure maintaining device 2, the second vacuum pressure maintaining device 3, and the vacuum glue filling device 4 are all independently connected to a vacuum pump.

[0033] A product preheating device (not shown) is connected to the feed inlet of the atmospheric pressure glue filling device 1, and a glue curing device (not shown) is connected to the discharge outlet of the second vacuum pressure maintaining device 3.

[0034] See Figures 2 - 5 As shown, a first transfer device 6 is fixedly installed in the chambers of both the atmospheric pressure glue filling device 1 and the vacuum glue filling device 4, and a second transfer device 7 is fixedly installed in the chambers of both the first vacuum pressure maintaining device 2 and the second vacuum pressure maintaining device 3.

[0035] The first transfer device 6 includes a first fixing frame 61, a first transfer conveyor 62, and a positioning and adjusting device 63. The first transfer conveyor 62 is fixedly installed at the upper end of the first fixing frame 61. The positioning and adjusting device 63 is fixedly connected to the lower end of the first fixing frame 61. The positioning and adjusting device 63 is fixedly installed on the atmospheric pressure glue filling device 1 or the vacuum glue filling device 4. First limiting components 64 and second limiting components 65 are further provided at the front and rear ends of the first transfer conveyor 62.

The telescopic module 68 can slide towards an adjacent station and extend to the discharge end or the feed end of the second transfer device 7 at the adjacent station.

[0038] The glue filling method includes pre-glue filling of the product through the atmospheric pressure glue filling device 1. The glue filling amount of the pre-glue filling is only a part of the required glue filling amount of the product, that is, incomplete glue filling is completed. Then, the first vacuum pressure maintaining device 2 between the atmospheric pressure glue filling device 1 and the vacuum glue filling device 4 evacuates the air and maintains the pressure to remove the bubbles in the glue. Then, the vacuum glue filling device 4 performs secondary glue filling to complete the glue filling of the product. By dividing the glue filling method into two steps, the total glue filling time is shortened, and the glue filling efficiency is improved on the premise of ensuring the glue filling quality. Among them, the vacuum glue filling device is always in a vacuum state, and the first vacuum pressure maintaining device and the second vacuum pressure maintaining device are only connected to the vacuum glue filling device in a sealed vacuum state to prevent damage to the vacuum environment of the vacuum glue filling device.

[0039] The specific steps of glue filling include:

[0040] S1 Preheating: Place the product on the loading fixture, and transfer the fixture with the product to the preheating device for preheating before glue filling of the product. Then, the preheated product and the fixture are conveyed to the designated position through the conveyor belt.

[0041] S2 First transfer: The first transfer device 6 in the atmospheric pressure glue filling device 1 is docked with the conveyor belt in the preheating device, that is, the horizontal position and the transfer position are the same. The product and the fixture are picked up from the conveyor belt conveyed out of the preheating device, and the position of the fixture and the product is adjusted by the positioning and adjusting device 63 to make the product in the glue filling position. The clamping components on both sides of the first transfer conveyor device 62 clamp the product or the fixture to prevent the product from moving.

[0042] S3 Atmospheric pressure glue filling: The glue filling device installed above the atmospheric pressure glue filling device 1 is inserted into the product to fill the product with glue.

[0043] S4 Second transfer: The fixture and the product in the atmospheric pressure glue filling device 1 are transferred to the first vacuum pressure maintaining device 2 through the first transfer device 6, and the transfer of the product and the fixture is carried out to transfer the product and the fixture into the first vacuum pressure maintaining device 2. After the transfer is completed, the first transfer device 6 of the atmospheric pressure glue filling device 1 retracts, and the subsequent transfer of the product from the preheating device to the atmospheric pressure glue filling device 1 is carried out, that is, S2 is repeated.

[0044] During the first pressure holding of S5, after the first transfer device 6 of the atmospheric pressure glue filling device 1 is completely separated from the first vacuum pressure holding device 2, the sealed opening and closing door 5 fixedly installed on the first vacuum pressure holding device 2 is started, so that the internal space of the first vacuum pressure holding device 2 forms a sealed state, and vacuum pumping is carried out through the connected vacuum pump. At this time, the vacuum glue filling device 4 and the second vacuum pressure holding device 3 carry out vacuum pumping simultaneously;

[0045] In the third transfer of S6, the first transfer device 6 in the vacuum glue filling device 4 transfers the products and fixtures that have completed vacuum pressure holding in the first vacuum pressure holding device 2. The transfer method is the same as that of the first transfer device 6 of the atmospheric pressure glue filling device 1. After the products are transferred, the sealed opening and closing door 5 is closed, so that the space connection between the vacuum glue filling device 4 and the first transfer device 6 is closed. The first vacuum pressure holding device 2 repeats S4 and S5;

[0046] In the vacuum glue filling of S7, after the vacuum glue filling device 4 completes all the glue filling work, the sealed opening and closing door 5 between the vacuum glue filling device 4 and the second vacuum pressure holding device 3 is opened to connect the inner cavities of the vacuum glue filling device 4 and the second vacuum pressure holding device 3. After the products are transferred into the second vacuum pressure holding device 3 through the first transfer device 6 inside the vacuum glue filling device 4, the sealed opening and closing door 5 between the vacuum glue filling device 4 and the second vacuum pressure holding device 3 is closed. The second vacuum pressure holding device 3 performs vacuum pressure holding. After the pressure holding is completed, the sealed opening and closing door 5 at its discharge end is opened, and the products are transferred to the curing device for curing the glue inside the products. After the products and fixtures are transferred out of the second vacuum pressure holding device 3, the sealed opening and closing door 5 at its discharge end is closed and vacuum pumping is carried out again.

[0047] In the step S3, the glue filling time of the atmospheric pressure glue filling is the pressure holding time of the first vacuum pressure holding device 2 or the glue filling time of the vacuum glue filling device 4.

[0048] In the step S5, the vacuum pumping time of the first vacuum pressure holding device 2 and the time when the product pressure holding is completed are the same as the glue injection time of the vacuum glue filling device 4.

[0049] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modification or change made by those of ordinary skill in the art according to the content disclosed in the present invention shall be included in the protection scope recorded in the claims.
