[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0032] Example, see attached document Figure 1The present invention provides a rotary dispensing and vacuum pressing device, including a supporting rotary table 100. The supporting rotary table 100 is driven by a structure similar to a servo motor and a divider, enabling precise control of rotation angle and forward / reverse rotation. Several auxiliary support frames 900 are arranged below the supporting rotary table 100, and rotary table support wheels are arranged on the upper end of the auxiliary support frames 900, which abut against the lower end face of the supporting rotary table 100. The device also includes a downward vacuum pressing device 500, an automatic dispensing device 600, an auxiliary part placement seat 300, and an auxiliary part transfer device 400. The system employs a servo gantry combined with an automatic clamp to grip and transfer workpieces from the auxiliary component placement seat 300. During the product assembly process, adhesive is first injected into workpiece one, then workpiece two is placed over the opening of workpiece one, and finally, workpiece two is pressed together with workpiece one to seal workpiece one. The support turntable 100 is equipped with at least two workpiece placement fixtures 200. During operation, one fixture 200 works in conjunction with the downward-pressing vacuum pressing device 500 and the automatic adhesive dispensing device 600 to complete the adhesive dispensing and pressing operations, while the other is used for pre-loading workpiece one, as shown in the attached diagram. Figure 2 As shown, the workpiece placement fixture 200 includes a fixture mounting base 210, a lower vacuum pressing shell 220 fixedly mounted on the fixture mounting base 210, and a workpiece mounting seat 230 disposed inside the lower vacuum pressing shell 220. The workpiece mounting seat 230 is used to place workpiece one. In this embodiment, the workpiece mounting seat 230 has a two-part structure, referred to as the first mounting seat and the second mounting seat respectively. The first mounting seat and the second mounting seat are each driven by a mounting seat driving device 240. The mounting seat driving device 240 can generally be in the form of a linear drive cylinder. The first mounting seat and the second mounting seat can approach or separate under the drive of the two mounting seat driving devices 240. When the first mounting seat and the second mounting seat are combined together, on the one hand, they support workpiece one from the bottom, and on the other hand, they can clamp workpiece one from both sides to ensure stability during operation. Figure 3 ~Appendix Figure 4As shown, the downward vacuum pressing device 500 includes a housing downward pressing drive device 520, a pressing drive device 540, and an upper vacuum pressing housing 510 adapted to the lower vacuum pressing housing 220. The housing downward pressing drive device 520 is drivenly connected to the lower vacuum pressing housing 220. A workpiece pressing block 530 is provided inside the upper vacuum pressing housing 510. The pressing drive device 540 is drivenly connected to the workpiece pressing block 530. A vacuum port 511 is provided on the side of the lower vacuum pressing housing 220. The vacuum port 511 is connected to a vacuum device. During vacuum pressing operations, the workpiece placement fixture 200 moves to the downward vacuum pressing device. The lower vacuum pressing housing 220 is placed below the upper vacuum pressing housing 510 under the drive of the housing pressing drive device 520. This causes the lower vacuum pressing housing 220 and the upper vacuum pressing housing 510 to fit together, forming a sealed vacuum pressing space. To improve sealing, an elastic sealing ring 270 is provided around the opening of the lower vacuum pressing housing 220. The vacuum pressing space is then evacuated to a near-vacuum state using a vacuum pump. The pressing drive device 540 then drives the workpiece pressing block 530 to press down, completing the pressing step. To ensure the pressing effect, the pressing drive device 540 typically uses a linear hydraulic cylinder, as shown in the attached diagram. Figure 5 ~Appendix Figure 6 As shown, the automatic glue dispensing device 600 includes a glue storage tank 610, a glue dispensing pipe 620, and a glue dispensing drive device 630. The glue dispensing pipe 620 is connected to the glue storage tank 610, and the glue dispensing drive device 630 is driven to connect to the glue dispensing pipe 620. The glue dispensing drive device 630 can drive the pipe opening of the glue dispensing pipe 620 to move. The automatic glue dispensing device 600 also includes a glue collection tray 640. The pipe opening of the glue dispensing pipe 620 can move above the glue collection tray 640 under the drive of the glue dispensing drive device 630. The glue collection tray 640 is mainly for collecting the glue residue at the pipe opening to avoid contaminating other equipment.

[0033] In one embodiment, to prevent the support turntable 100 from directly bearing the downward pressure of the vacuum pressing device 500, the tooling mounting base 210 and the support turntable 100 are elastically connected by several base return springs 250, so the tooling mounting base 210 and the support turntable 100 are not in direct contact. Meanwhile, a tooling downward pressing support seat 800 is provided below the upper vacuum pressing housing 510, located below the support turntable 100. A tooling bottom support seat 260 is fixedly connected to the tooling mounting base 210, located below the support turntable 100. This structure... During the rotation of the support turntable 100, due to the elastic force of the base return spring 250, the lower end of the tooling bottom support 260 is higher than the height of the tooling pressing support 800, and the two will not collide. During the pressing process of the pressing vacuum pressing device 500, the lower end surface of the tooling bottom support 260 can be pressed to abut against the upper end surface of the tooling pressing support 800. At this time, there is still a gap between the tooling mounting base 210 and the support turntable 100. At this time, the downward pressure of the pressing vacuum pressing device 500 is borne by the tooling pressing support 800 and will not affect the support turntable 100.

[0034] In one embodiment, in order to correctly identify the product installation status on each tooling, an array of workpiece sensing devices 700 is also provided. Each set of workpiece sensing devices 700 includes mutually compatible photoelectric switch transmitters and photoelectric switch receivers. By adjusting the installation height of the photoelectric switch transmitters and photoelectric switch receivers, their sensing height can be set. After being adjusted to a suitable height, it can identify whether the corresponding workpieces are installed on the two workpiece placement tooling 200 and the auxiliary part placement seat 300.

[0035] The workflow of a rotary dispensing and vacuum pressing device mentioned in this embodiment is as follows:

[0036] In the initial state, two workpiece placement fixtures 200 are positioned, one below the pressure-type vacuum pressing device 500 and the other at the loading station. During operation, the two workpiece placement fixtures 200 exchange positions to complete the loading and unloading operations. At the start of the operation, workpiece one is first installed on the workpiece placement fixture 200 at the loading station. At this time, workpiece one is clamped from both sides by the first and second mounting seats. Simultaneously, workpiece two is placed on the auxiliary part placement seat 300. Then, the workpiece placement fixture 200 rotates to be below the pressure-type vacuum pressing device 500. Then, the glue injection drive device 630 drives the nozzle of the glue injection pipe 620 to move to the glue injection position of workpiece one inside the workpiece placement fixture 200 for glue injection. After the glue injection is completed, the glue injection drive device 630 drives the glue injection pipe 620 to leave the workpiece placement fixture 200. The auxiliary part transfer device 400 picks up workpiece 2 from the auxiliary part placement seat 300 and places it on the glue injection port of workpiece 1. Then, the housing pressing drive device 520 drives the upper vacuum pressing housing 510 to press down until the upper vacuum pressing housing 510 and the lower vacuum pressing housing 220 are fitted together to form a closed vacuum pressing space. At this time, the vacuum pressing space is evacuated by the vacuum pumping device until it reaches a near-vacuum state (generally 500 mmHg in this embodiment). Then, the pressing drive device 540 drives the workpiece pressing block 530 to press down, finally pressing workpiece 2 and workpiece 1 together to seal workpiece 1. While the vacuum pressing process is in progress, the auxiliary part placement seat 300 and another workpiece placement fixture 200 simultaneously carry out the installation of the next workpiece 1 and workpiece 2. This cycle is repeated to realize rotary production line production.
