Description

Technical Field

[0001] This utility model relates to the field of glue discharge technology for glue guns, and in particular to a glue discharge device. Background Technology

[0002] In the vehicle production process, the adhesive application process for the four doors and one hood of the body-in-white is a core step to ensure the integrity and sealing of the body structure. As a key adhesive application tool in the adhesive application process, the operating status of the adhesive gun is directly related to the adhesive application quality of the body.

[0003] Currently, traditional glue guns widely used in the market typically require manual periodic glue discharge to ensure coating quality. Specifically, operators manually press the glue gun handle to discharge the glue. However, manual operation makes it difficult to precisely control the discharge interval, easily leading to delayed discharge. This causes the glue to harden inside the glue gun, hose, and pump, forming hard lumps that easily embed in the gaps of delicate internal components. Cleaning is extremely difficult, maintenance costs are high, and frequent equipment blockages severely disrupt production continuity and reduce efficiency. Therefore, there is an urgent need to develop a new glue discharge device. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a glue discharge device, which aims to solve the technical problem that the glue discharge process of traditional glue guns is usually done by manually pressing the glue gun handle. However, manual operation makes it difficult to accurately control the glue discharge time interval, which easily leads to untimely glue discharge, resulting in equipment blockage, extremely difficult cleaning, and high maintenance costs.

[0005] The purpose of this utility model is to provide a glue discharge device, comprising:

[0006] The mounting bracket assembly includes a first mounting bracket, a second mounting bracket disposed at one end of the first mounting bracket, and a placement cylinder connected to the first mounting bracket. The first mounting bracket is provided with a cylinder, and the end of the piston rod of the cylinder is connected to a stock, which has a U-shaped structure.

[0007] A glue gun includes a gun body, a nozzle at one end of the gun body, a fixing part at the other end of the gun body, and a handle movably connected to the gun body. The nozzle is located inside the placement tube, and the handle is located inside the stock.

[0008] The control component includes a solenoid valve and a timer switch connected to the solenoid valve. The solenoid valve is located on the side of the first mounting bracket away from the glue gun. One side of the solenoid valve is connected to the compressor through several first air pipes, and the other side of the solenoid valve is connected to the cylinder through several second air pipes. The timer switch is located at the end of the first mounting bracket away from the second mounting bracket.

[0009] Compared to existing technologies, the advantages of this glue discharge device are as follows: Automatic, timed glue discharge from the glue gun is achieved by setting up a mounting bracket assembly, a cylinder, and a control assembly. Specifically, the piston rod end of the cylinder is equipped with a gunstock for actuating the glue gun handle. The control assembly includes a timer switch and a solenoid valve. The timer switch is used to time the opening and closing of the internal air passage of the solenoid valve. The solenoid valve is connected to a compressor through a first air pipe to ensure a stable supply of compressed air. The solenoid valve is also connected to the cylinder through a second air pipe to allow compressed air to push the piston rod inside the cylinder, enabling the gunstock to actuate the glue gun handle and complete the glue discharge action. This avoids the uncertainty of manual glue discharge, improves glue discharge efficiency, reduces labor costs, and effectively prevents the glue from hardening inside the equipment, ensuring normal operation of the equipment and improving the production quality and efficiency of the glue application process for the four doors and one cover of the body-in-white.

The first horizontal plate, the second horizontal plate, and the vertical plate are integrally connected to form a U-shaped structure. The first horizontal plate has a mounting hole. The cylinder body of the cylinder is fixed on the side of the first horizontal plate opposite to the second horizontal plate. The piston rod of the cylinder passes through the mounting hole. The solenoid valve is fixed on the side of the second horizontal plate away from the first horizontal plate.

[0024] Please see Figs. 1 to 4 The image shows a glue discharge device according to the present invention, including a mounting frame assembly 10. The mounting frame assembly 10 is used to mount and fix a glue gun 40 and a control component. Specifically, the mounting frame assembly 10 includes a first mounting frame 11, a second mounting frame 12 disposed at one end of the first mounting frame 11, and a placement cylinder 13 connected to the first mounting frame 11. The first mounting frame 11, the second mounting frame 12, and the placement cylinder 13 can be connected to a single structure by welding or bolt fastening. The first mounting frame 11 is provided with a cylinder 20. The end of the piston rod 21 of the cylinder 20 is connected to a gunstock 30. The gunstock 30 has a U-shaped structure, and the opening size of the gunstock 30 is adapted to the shape of the handle portion 44 in the glue gun 40, so that the gunstock 30 can tightly wrap around and effectively touch the handle portion 44 in the glue gun 40 in subsequent actions, thereby realizing the glue discharge operation of the glue gun 40.

[0025] In this embodiment, the first mounting bracket 11 includes a first horizontal plate portion 111, a second horizontal plate portion 112, and a vertical plate portion 113. The first horizontal plate portion 111, the second horizontal plate portion 112, and the vertical plate portion 113 are integrally connected to form a U-shaped structure. The first horizontal plate portion 111 is provided with a mounting hole 101. The cylinder body of the cylinder 20 is fixed on the side of the first horizontal plate portion 111 opposite to the second horizontal plate portion 112. The piston rod 21 of the cylinder 20 passes through the mounting hole 101. A solenoid valve 51 is fixed on the side of the second horizontal plate portion 112 away from the first horizontal plate portion 111. A time control switch 52 is fixed on the side of the vertical plate portion 113 away from the first horizontal plate portion 111.

[0026] Furthermore, a placement cylinder 13 is provided at the end of the first horizontal plate portion 111 away from the vertical plate portion 113. The placement cylinder 13 is inclined, and the angle between the axial direction of the placement cylinder 13 and the plate surface of the first horizontal plate portion 111 is 30°-45°, so as to facilitate the placement of the nozzle portion 42 of the glue gun 40 and improve the convenience of subsequent heating and glue discharge operations. As a specific example, in this embodiment, the angle between the axial direction of the placement cylinder 13 and the plate surface of the first horizontal plate portion 111 is 30°, and the placement cylinder 13 is fixedly connected to the end of the first horizontal plate portion 111 by welding.

[0027] Furthermore, a second mounting bracket 12 is provided at the port of the first mounting bracket 11. The second mounting bracket 12 includes a mounting plate portion 121 and two connecting rod portions 122. The two ends of one side of the mounting plate portion 121 are fixedly connected to the first horizontal plate portion 111 and the second horizontal plate portion 112 respectively through the connecting rod portions 122. A heater 70 is fixedly provided on the side of the mounting plate portion 121 away from the first horizontal plate portion 111.

[0028] As an example, the glue gun 40 in this application includes a gun body 41, a nozzle 42 located at one end of the gun body 41, a fixing part 43 located at the other end of the gun body 41, and a handle 44 movably connected to the gun body 41. The nozzle 42 is located inside the placement tube 13, the fixing part 43 is used to connect external devices, and the handle 44 is located inside the stock 30.

[0029] As an example, the control components in this application include a solenoid valve 51 and a timer switch 52 connected to the solenoid valve 51 by a signal. The solenoid valve 51 is located on the side of the first mounting bracket 11 away from the glue gun 40. One side of the solenoid valve 51 is connected to the compressor (not shown) through several first air pipes 61, and the other side of the solenoid valve 51 is connected to the cylinder 20 through several second air pipes 62. The timer switch 52 is located at the end of the first mounting bracket 11 away from the second mounting bracket 12. It should be understood that the design of the cylinder 20, the solenoid valve 51 and the timer switch 52 all adopt the prior art, which will not be described in detail here. In actual use, the compressor is used to provide compressed air. When the time switch 52 controls the solenoid valve 51 to open, the air passage inside the solenoid valve 51 is opened. The compressed air provided by the compressor will enter the solenoid valve 51 through the first air pipe 61 under the action of the air pressure difference, and enter the cylinder 20 through the second air pipe 62, pushing the piston rod 21 and thus realizing the lifting action of the piston rod 21. When the time switch 52 controls the solenoid valve 51 to close, the air passage inside the solenoid valve 51 is closed, the supply of compressed air in the cylinder 20 is cut off, and the piston rod 21 in the cylinder 20 will gradually fall back to the initial position under the action of the return spring or the reverse flow of compressed air to the solenoid valve 51.

[0030] Furthermore, the glue discharge device also includes a heater 70, which is fixed on the second mounting bracket 12 on the side opposite to the first mounting bracket 11. The heater 70 is provided with a heating chamber 71, which is adapted to the nozzle part 42, and the axial direction of the heating chamber 71 is arranged along the height direction of the first mounting bracket 11. When the glue gun 40 is working in a low-temperature environment, the glue gun 40 can be manually moved so that the nozzle part 42 of the glue gun 40 enters the heating chamber 71 of the heater 70 for precise heating, thereby effectively maintaining the fluidity of the glue in the nozzle part 42 and preventing the glue from hardening and clogging.

[0031] In practical use, the working principle of the glue discharge device of this utility model is as follows: The time control switch 52 continuously times according to the time interval preset by the operator. When the time reaches the preset glue discharge time interval, the internal circuit of the time control switch 52 generates an electrical signal pulse and transmits the signal to the solenoid valve 51. After receiving the signal, the internal electromagnetic coil of the solenoid valve 51 is energized, generating electromagnetic force, which pushes the valve core to move, thus opening the air passage inside the solenoid valve 51 that was in a closed state. At this time, compressed air from the compressor enters the solenoid valve 51 through the first air pipe 61 under the action of air pressure difference, and is stably delivered to the cylinder 20 through the second air pipe 62. After the compressed air enters the cylinder 20, it pushes the piston and piston rod 21 inside the cylinder 20 to move upward in a linear motion. The piston rod 21 gradually rises upward, and the rising action of the piston rod 21 drives the gunstock 30 to move upward synchronously. Since the gunstock 30 tightly wraps the handle part 44 of the glue gun 40, the gunstock 30 will touch the handle part 44 during the upward movement. When the handle 44 of the glue gun 40 is activated, the glue discharge mechanism inside the glue gun 40 starts to work, discharging the glue inside the glue gun and completing one glue discharge action.

[0032] When the glue discharge action is completed, the timer switch 52 controls the solenoid valve 51 to close, that is, the air passage inside the solenoid valve 51 returns to the closed state, and the compressed air that originally pushed the piston rod 21 in the cylinder 20 loses its source of air supply. At this time, the air pressure distribution inside the cylinder 20 changes, resulting in a pressure difference on both sides of the piston. The remaining compressed air in the cylinder 20 will flow back into the solenoid valve 51 in the opposite direction of the air intake, that is, from the cylinder 20 through the second air pipe 62. The internal structure of the solenoid valve 51 will allow this part of the gas to flow out through a specific channel or valve port. Specifically, the solenoid valve 51 can be designed with a one-way valve or throttling structure. When the compressed air flows back in reverse, the gas can pass through under a certain resistance, so that the piston rod 21 in the cylinder 20 will fall back smoothly to the initial position under the pressure difference generated by the reverse flow of gas and its own gravity, completing the reset action after one glue discharge cycle, and waiting for the next timed glue discharge command. This precise timing control method effectively avoids the problem of glue hardening and clogging caused by untimely manual glue discharge, thus improving production efficiency and equipment stability.

[0033] In summary, the beneficial effects of the glue discharge device of this utility model are as follows: Automatic timed glue discharge from the glue gun is achieved by setting up a mounting bracket assembly, a cylinder, and a control assembly. Specifically, the piston rod end of the cylinder is equipped with a gunstock for triggering the glue gun handle. The control assembly includes a timer switch and a solenoid valve. The timer switch is used to time the opening and closing of the internal air passage of the solenoid valve. The solenoid valve is connected to the compressor through a first air pipe to ensure a stable supply of compressed air. The solenoid valve is also connected to the cylinder through a second air pipe to allow compressed air to push the piston rod inside the cylinder, enabling the gunstock to trigger the glue gun handle and complete the glue discharge action. This avoids the uncertainty of manual glue discharge, improves glue discharge efficiency, reduces labor costs, and effectively prevents the glue from hardening inside the equipment, ensuring the normal operation of the equipment and improving the production quality and efficiency of the glue application process for the four doors and one hood of the body-in-white. Furthermore, this application also installs a heater on the mounting bracket assembly to heat the glue gun nozzle, effectively coping with low-temperature environments, preventing the glue at the nozzle from hardening and clogging, reducing equipment maintenance costs, and improving the continuity and stability of the glue application operation.
