[0002] With the application of adhesive coating technology in multiple processes of automobile production, the number of adhesive coating equipment has increased dramatically. These machines frequently require replacement of the glue canisters. Currently, the replacement method involves manual operation to vent and inflate the equipment after the glue arrives, requiring manual valve switching and connection of a vacuum pump. This results in low glue canister replacement efficiency, severely impacting the adhesive coating efficiency in automobile production. Therefore, this paper proposes a pressure plate assembly and adhesive coating equipment specifically designed to address these issues. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, in order to achieve the above objectives, this utility model provides a pressure plate assembly suitable for a glue bucket 9, including: a pressure plate body 1 and a valve base 3 and a solenoid valve assembly disposed on the pressure plate body 1.

[0025] Specifically, the middle part of the pressure plate body 1 is coaxially provided with a ventilation chamber 2, and the upper end of the pressure plate body 1 is connected to a glue injection pump (not shown in the figure). The glue injection pump delivers the glue in the glue bucket 9 to the glue application valve (not shown in the figure), and then the glue is applied to the surface of the product through the glue application valve. The glue injection pump and the glue application valve are both relatively mature existing technologies, so they will not be described in detail.

[0026] A valve base 3 is provided on the outer wall of the pressure plate body 1. The valve base 3 has a first through hole 4 and a second through hole 5 that are interconnected inside. The first through hole 4 is aligned with the length direction of the valve base 3, and the second through hole 5 is aligned with the height direction of the valve base 3. That is, the first through hole 4 and the second through hole 5 are perpendicular to each other. The first through hole 4 is connected to the ventilation chamber 2, and the second through hole 5 (not shown in the figure) is connected to the vacuum pump (not shown in the figure). The vacuum pump fills and evacuates air into the second through hole 5, and then fills and evacuates air into the glue bucket 9 through the first through hole 4 and the ventilation chamber 2 in sequence, so as to facilitate the removal and placement of the pressure plate body 1 from the glue bucket 9.

[0027] The solenoid valve assembly is located on the top surface of the valve base 3. The solenoid valve assembly controls the second through hole 5 to switch flexibly between the closed and open states, eliminating the need for manual operation of the valve switch and manual connection of the vacuum pump, and making the replacement of the glue tank 9 more efficient.

[0028] In addition, the vacuum pump and solenoid valve assembly are connected through a control system. Preferably, the control system is a PLC control system, which controls the start and stop of the vacuum pump and the opening and closing of the solenoid valve assembly. At the same time, a vacuum sensor is installed in the pressure plate body 1. The vacuum sensor can detect the vacuum level inside the glue tank 9 and feed it back to the PLC control system. During operation, the PLC control system can precisely control the opening and closing of the second through hole 5 and the start and stop of the vacuum pump according to the vacuum level inside the glue tank 9.

[0029] When replacing glue bucket 9, the control system activates the vacuum pump and automatically switches the second through-hole 5 from the closed state to the open state via the solenoid valve assembly. The vacuum pump fills the old glue bucket with air, and the pressure plate body 1 is pushed out of the old glue bucket by the air pressure. The old glue bucket is removed from the workstation, and the new glue bucket is installed on the workstation. The pressure plate body 1 descends into the new glue bucket, and the vacuum pump discharges the gas in the new glue bucket until the pressure plate body 1 stably holds the glue in the new glue bucket, thus completing the replacement of glue bucket 9. No manual intervention is required, which effectively saves manpower, improves the efficiency of replacing glue bucket 9, reduces the downtime of the glue application equipment during the glue bucket replacement process, and thus effectively improves the glue application efficiency in the automobile production process.

[0030] like Figure 4 As shown, the solenoid valve assembly includes: an assembly cavity disposed inside the assembly housing 10; a movable iron core 11 slidably disposed within the assembly cavity; the axial direction of the movable iron core 11 being consistent with the height direction of the assembly housing 10; a piston head 12 disposed at the lower end of the movable iron core 11; the piston head 12 being located above the second through hole 5 and adapted to the second through hole 5; and a coil 13 disposed at the upper end of the assembly cavity; the coil 13 being located above the movable iron core 11, driving the movable iron core 11 to move up and down. Preferably, a sliding sleeve 14 is disposed at the upper end of the movable iron core 11; the sliding sleeve 14 is slidably connected to the inner wall of the assembly cavity; the sliding sleeve 14 can limit and correct the path of the movable iron core 11 during its up and down movement, preventing wobbling during its movement, and ensuring that the piston head 12 disposed at the lower end of the movable iron core 11 can precisely engage with the second through hole 5.

[0031] It should be noted that a ventilation hole 8 is provided at the lower end of the assembly shell 10. The ventilation hole 8 is perpendicular to the second through hole 5, and the second through hole 5 is connected to the vacuum pump through the ventilation hole 8.

[0032] Additionally, a return spring 15 is provided on the top surface of the sliding sleeve 14. The lower end of the return spring 15 is connected to the top surface of the sliding sleeve 14, and the upper end of the return spring 15 is connected to the top surface of the assembly cavity. In the initial state, the coil 13 is not energized. Under the holding force of the return spring 15, the moving iron core 11 drives the piston head 12 to block the second through hole 5. At this time, the first through hole 4 and the vacuum pump are not connected, and the vacuum pump cannot fill or exhaust the inside of the glue bucket 9. When the solenoid valve assembly is energized, the magnetic attraction force provided by the coil 13 to the moving iron core 11 overcomes the holding force of the return spring 15 to drive the moving iron core 11 to move away from the second through hole 5 until the piston head 12 leaves the second through hole 5. At this time, the second through hole 5 and the vacuum pump are connected, and the vacuum pump can fill or exhaust the inside of the glue bucket 9.

[0033] In one embodiment of this utility model, a limiting sleeve 7 is provided inside the assembly cavity. The outer side wall of the limiting sleeve 7 is fixedly connected to the inner side wall of the assembly cavity. The limiting sleeve 7 is slidably connected to the moving iron core 11. The limiting sleeve 7 further limits the path of the moving iron core 11 when it moves up and down, so that the piston head 12 at the lower end of the moving iron core 11 is precisely matched with the second through hole 5.

[0034] In one embodiment of this utility model, a sealing ring 6 is provided on the outer peripheral side of the lower end of the pressure plate body 1. The outer side wall of the sealing ring 6 is attached to the inner side wall of the glue bucket 9. The sealing ring 6 can improve the sealing strength between the pressure plate body 1 and the inner wall of the glue bucket 9, effectively prevent gas leakage inside the glue bucket 9, and make the pressure plate body 1 rise stably under the supporting force of air pressure.

[0035] In the initial state of use, the coil 13 is not energized. Under the holding force of the return spring 15, the moving iron core 11 drives the piston head 12 to block the second through hole 5. At this time, the first through hole 4 and the vacuum pump are not connected, and the vacuum pump cannot fill or exhaust the glue bucket 9. When replacing the glue bucket 9, the control system controls the vacuum pump to start, the solenoid valve assembly is energized, and the magnetic attraction force provided by the coil 13 to the moving iron core 11 overcomes the holding force of the return spring 15 to drive the moving iron core 11 to move away from the first through hole 4 until the piston head 12 leaves the second through hole 5. At this time, the first through hole 4 and the vacuum pump are connected, and the vacuum pump can fill the glue bucket 9 with air. The pressure force is used to push the pressure plate body 1 out of the old glue bucket. The old glue bucket is removed from the workstation, the new glue bucket is installed on the workstation, the pressure plate body 1 descends into the glue bucket 9, and the vacuum pump exhausts the gas in the glue bucket 9 until the pressure plate body 1 stably presses the glue in the glue bucket 9, completing the replacement of the glue bucket 9.

[0036] In summary, the vacuum pump remains connected to the second through-hole 5. When the glue can 9 needs to be replaced, the control system automatically controls the second through-hole 5 to switch from the closed state to the open state through the solenoid valve assembly. This eliminates the need for manual operation of the valve switch and manual connection of the vacuum pump, effectively improving the efficiency of replacing the glue can 9 and thus improving the glue application efficiency in the automobile production process.
