Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a glue injection mechanism. Background Technology

[0002] Wooden door step frames, also known as stepped door frames, refer to door panels with a raised section at the bottom. During installation, the bottom of the door panel is inserted into a groove in the door frame to achieve a closed and stable seal. Currently, the processing methods for wooden door step frames have the following problems: First, wooden door step frames consist of a door frame panel and a step panel, requiring multiple independent machines to form and process each, resulting in high equipment investment and large floor space requirements. Second, the door frame panel and step panel need to be manually glued and fixed, which is labor-intensive, inefficient, and the bonding quality is greatly affected by the worker's skill level, making it difficult to guarantee product consistency and meet the increasing production capacity requirements of customized wooden doors. Utility Model Content

[0003] To overcome the problems existing in related technologies, this utility model provides a glue injection mechanism. By driving the glue injection component to move precisely through the transverse component and adjusting the component to achieve fine height adjustment, combined with the chip removal component to remove impurities in the groove, the uniformity and firmness of glue injection can be improved, thereby improving the processing quality and efficiency of wooden door step sleeves.

[0007] The second end plate is provided with a shaft hole, and the transverse component is a cylinder-driven structure or a servo-driven structure.

[0008] In some embodiments, the cylinder drive structure includes a cylinder, and the output shaft of the cylinder passes through a shaft hole and is connected to the slide.

[0010] In some embodiments, the adjustment assembly includes a mounting plate, a counter base, a counter, and an adjustment shaft;

[0011] The mounting plate is located at the bottom of the slide and is connected to the slide shaft. The counter seat is mounted on the mounting plate, and the counter is mounted on the counter seat. The adjusting shaft passes through the counter seat, the counter, and the mounting plate and is threadedly connected to the slide. The end of the adjusting shaft is provided with a knob for fingers to hold.

[0012] In some embodiments, the counter is a digital displacement counter, whose detection end is connected to the adjustment shaft to detect the rotational displacement of the adjustment shaft in real time and convert it into the height adjustment of the glue dispensing assembly for display.

[0013] In some embodiments, the debris removal assembly includes a connecting plate, an air blowing fixing seat, a first air blowing seat, and a second air blowing seat;

[0014] The connecting plate is located on top of the slide block and connected to the slide shaft. The air blowing fixing seat and the glue injection seat are arranged sequentially on the connecting plate along the conveying direction of the plate.

[0015] The air-blowing fixing seat has an air chamber. The first air-blowing seat and the second air-blowing seat are provided with air passages communicating with the air chamber. The first air-blowing seat and the second air-blowing seat are located at the top of the air-blowing fixing seat. The second air-blowing seat is located between the first air-blowing seat and the glue injection seat. The air-blowing direction of the first air-blowing seat and the second air-blowing seat is in the same direction as the axial direction of the glue dispensing rod.

[0016] The first air-blowing seat is a plate-shaped structure, and the thickness of the first air-blowing seat is the same as the diameter of the dispensing rod.

[0017] In some embodiments, a pressure roller assembly is also included, the pressure roller assembly including a plurality of pressure roller mounting seats and a pressure roller rotatably connected to each pressure roller mounting seat, the pressure roller mounting seats being fixed on the side of the first end plate facing the second end plate, the pressure roller being located between the dispensing rod and the slide, and the outer peripheral surface of the pressure roller being in rolling contact with the lower surface of the sheet material.

[0018] In some embodiments, the dispensing assembly includes a heat insulation cover that covers the dispensing base; the heat insulation cover contains an electric heating wire and a temperature sensor.

[0019] In some embodiments, the dispensing rod is a hollow ceramic electric heating tube.

[0020] Compared with existing technologies, the advantages of the above-mentioned glue injection mechanism are as follows:

[0021] The transverse component adopts a cylinder or servo drive structure, which works with the optical axis for movement guidance. This allows the glue injection component to move smoothly along the board conveying direction, realizing the glue injection work on the grooved structure of the board. The glue outlets evenly distributed on the outer periphery of the glue dispensing rod are in the same direction as the transverse direction, ensuring that the glue can be evenly filled in the grooved structure of the board, avoiding glue leakage or local accumulation, and improving the utilization rate of the wood board.

[0022] The first air blowing seat, the second air blowing seat, and the air blowing fixing seat are used to remove dust and wood chips from the groove of the wood board before glue injection. The width of the air blowing port of the first air blowing seat is matched with the axial length of the glue dispensing rod to ensure that there are no dead corners in the cleaning of chips, avoid impurities from affecting the glue injection and adhesion effect, and significantly reduce the risk of deformation and falling off of the stepped board.

[0023] The glue injection assembly is raised and lowered by rotating the adjustment shaft, and the height adjustment is displayed in real time by a digital displacement counter. This solves the problem of traditional glue injection mechanisms relying on manual experience for adjustment. The glue injection position accuracy can be quantified and controlled, improving the consistency of door frame molding.

[0024] The pressure roller rolls in contact with the lower surface of the board, which helps to fix the board during the glue injection process, preventing it from tilting or shifting, ensuring the alignment accuracy of the glue injection position with the subsequent pressing process, and further improving the overall stability of the door frame.

[0025] By adding a heat insulation cover to the dispensing base and making the dispensing rod a ceramic electric heating tube, the temperature can be adjusted according to the characteristics of the glue, preventing the glue from solidifying and clogging the dispensing hole at low temperatures. At the same time, the ceramic material is corrosion resistant, extending the service life of the dispensing component, and is suitable for the processing needs of various types of glue.

[0049] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0050] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms “a,” “the,” and “the” used in this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0051] It should be understood that although the terms "first," "second," "third," etc., may be used in this invention to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this invention, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0052] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0053] See Figures 1 to 4 This utility model proposes a glue injection mechanism 104, which is applied to a CNC integrated machine 10 for wooden door step sleeves. Specifically, it includes a base 1, a horizontal movement component 2, an adjustment component 3, a glue injection component 4, and a dust removal component 5. The horizontal movement component 2 is disposed on the base 1 and drives the glue injection component 4 to move horizontally. The adjustment component 3 is used to adjust the horizontal height of the glue injection component 4.

[0054] The glue injection assembly 4 includes a slide 41, a glue injection seat 42, and a glue dispensing rod 43. The slide 41 is connected to the output end of the transverse movement assembly 2. The slide 41 is vertically provided with a sliding shaft 44. The two ends of the sliding shaft 44 are respectively connected to the glue injection seat 42 and the adjustment assembly 3. The output end of the adjustment assembly 3 is connected to the slide 41. The glue injection seat 42 is provided with a glue injection cavity. The glue dispensing rod 43 is a hollow rod-shaped structure and communicates with the glue injection seat 42. The outer periphery of the glue dispensing rod 43 has a plurality of glue dispensing holes 45 distributed along the axial direction. The axial direction of the glue dispensing rod 43 is in the same direction as the transverse movement direction of the slide 41.

[0055] One side of the base 1 can be fixed to the CNC integrated machine for processing wooden door frames with bolts. The base 1 can be a frame structure or a plate structure. The middle of the plate 7 structure is set as a hollow area, and the glue injection component 4 can move freely in the hollow area. The frame can be a metal welding structure or an aluminum alloy profile splicing structure.

[0056] The transverse component 2 is used to drive the horizontal transverse movement of the dispensing component 4. The dispensing component 4 and the base 1 are in sliding engagement. Specifically, the transverse component 2 can be driven by a guide rail or a linear bearing with an optical axis. The driving method of the transverse component 2 includes, but is not limited to, cylinder drive, servo motor drive or stepper motor drive. The cylinder drive can be a single-acting cylinder or a double-acting cylinder, and the servo motor drive can be paired with a ball screw or synchronous belt drive mechanism.

[0057] Adjustment component 3 can be adjusted manually or electrically. Manual adjustment can be achieved through a knob and screw thread, while electric adjustment can be achieved through a motor and encoder. Adjustment component 3 can adjust the horizontal height of the glue dispensing component 4, that is, adjust the horizontal height of the glue dispensing rod 43, to accommodate different thicknesses of board 7 or the height of the groove in board 7.

[0058] The glue injection assembly 4 has a glue injection seat 42 connected to an external glue supply device. The glue supply device delivers hot melt glue with a certain temperature to the glue injection chamber of the glue injection seat 42 and applies injection pressure to make the hot melt glue flow out from the glue outlet 45 of the glue outlet rod 43, so as to realize the glue injection work on the board 7.

[0059] When the horizontal movement component 2 drives the glue injection component 4 to move horizontally, the glue injection component 4 moves closer to or further away from the base 1 to be installed and fixed on the mounting side of the CNC integrated machine for processing wooden door frames. When the slide 41 is close to the mounting side, the glue dispensing rod 43 is in the glue injection position. When the CNC integrated machine for processing wooden door frames conveys the board 7 to the glue injection mechanism 104, the glue injection work of the board 7 can be realized. When the slide 41 is away from the mounting side, the glue dispensing rod 43 is in the avoidance position. At this time, the glue injection component 4 does not participate in the processing work of the CNC integrated machine for processing wooden door frames.

[0060] To facilitate understanding of the working principle of the glue injection mechanism 104, the following is a brief explanation of the structure of the CNC integrated machine 10 for wooden door step sleeves and its processing flow for wooden door step sleeves.

[0061] Please see Figure 5 and Figure 6 The CNC integrated machine 10 for wooden door step covers includes a frame 100, a first grooving mechanism 101, a second grooving mechanism 102, a lower grooving mechanism 103, a forming and pressing mechanism 105, a third grooving mechanism 106, and a fourth grooving mechanism 107 mounted on the frame 100. The glue injection mechanism 104 provided by this invention is located between the lower grooving mechanism 103 and the forming and pressing mechanism 105. The saw blades of the first grooving mechanism 101, the second grooving mechanism 102, the third grooving mechanism 106, and the fourth grooving mechanism 107 are horizontally arranged, meaning their rotation surfaces are parallel to the horizontal plane. The saw blade of the lower grooving mechanism 103 is vertically arranged, meaning its rotation surface is perpendicular to the horizontal plane, and the saw blade of the lower grooving mechanism 103 moves in the same direction as the board 7. The first grooving mechanism 101, the second grooving mechanism 102, and the third grooving mechanism 106 are all equipped with two grooving saw blades. Except for the differences in the grooving saw blades, the remaining structures of the first grooving mechanism 101, the second grooving mechanism 102, and the third grooving mechanism 106 are identical. The first grooving mechanism 101 includes a first pre-grooving saw blade 1011 and a second post-grooving saw blade 1022; the second grooving mechanism 102 includes a second pre-grooving saw blade 1021 and a second post-grooving saw blade 1022; the third grooving mechanism 106 includes a third pre-grooving saw blade 1061 and a third post-grooving saw blade 1062; and the fourth grooving mechanism 107 includes a fourth grooving saw blade 1071. Furthermore, the two saw blades of the first grooving mechanism 101, the second grooving mechanism 102, and the third grooving mechanism 106 rotate in opposite directions, which can prevent the problem of edge chipping of the board 7.

[0062] The processing flow of this CNC integrated machine for making 10 pairs of wooden door step covers is as follows:

[0063] Driven by the conveying system, the board 7 is conveyed to the working position of the first grooving mechanism 101, where the first grooving pre-saw blade 1011 performs preliminary grooving rough processing on the board 7, followed by the first grooving post-saw blade 1012 performing fine processing on the structure after the preliminary grooving. Next, the board 7 is moved to the working position of the second grooving mechanism 102, where the second grooving pre-saw blade 1021 performs a second grooving rough processing, followed by the second grooving post-saw blade 1022 performing fine processing on the structure after the second grooving. The board 7 is then conveyed to the working position of the lower grooving mechanism 103, where the lower grooving mechanism 103 performs a cutting operation, separating the board 7 into a stepped board 71 and a door frame board 72. The control system of the CNC integrated machine for processing wooden door frames controls the drive of the transverse component 2 according to a preset program, causing the glue injection component 4 to enter the glue injection station. The glue injection component 4 injects hot melt adhesive into the gap between the stepped board 71 and the door frame board 72. Subsequently, the step plate 71 and the door frame plate 72 are conveyed to the working position of the forming and pressing mechanism 105 for pressing and bonding, thereby obtaining a semi-finished wooden door step sleeve. After the step plate 71 and the door frame plate 72 are bonded and fixed, they are moved to the working position of the third grooving structure. Before the third grooving, the saw blade 1061 performs a third rough grooving on the semi-finished wooden door step sleeve, and then the saw blade 1062 after the third grooving performs fine processing on the structure after the third grooving. Finally, the semi-finished wooden door step sleeve is conveyed to the working position of the fourth grooving mechanism 107, where the fourth grooving saw blade 1071 performs a fourth grooving, thereby completing the processing of the wooden door step sleeve.

[0064] It should be noted that, on a single sheet 7, a groove is simply cut to form a shape like... Figure 6 The integrated wooden door step sleeve shown has a more complex processing procedure and process. Compared with the CNC integrated wooden door step sleeve machine 10 which uses grooving, sawing and gluing methods, the manufacturing cost is relatively higher.

[0065] In this embodiment, the integrated mechanical structure design enables precise positioning and height adjustment during the glue injection process. The lateral movement component 2 moves the glue injection component 4, allowing the glue dispensing rod 43 to enter or avoid the glue injection station. The adjustment component 3 fine-tunes the horizontal height of the glue dispensing rod 43 to adapt to different board thicknesses or groove heights. Simultaneously, the multi-hole design of the glue dispensing rod 43 ensures uniform glue distribution, guaranteeing the bonding strength between the door frame panel 72 and the step panel 71. The debris removal component 5 removes processing residues before glue injection, ensuring the cleanliness of the bonding surface. Compared to traditional manual glue injection methods, the glue injection mechanism 104 provided by this invention features high positioning accuracy, accurate glue volume control, and stable operating efficiency, effectively solving the problem of inconsistent bonding quality in split processing.

[0066] Furthermore, the base 1 has a first end plate 11 and a second end plate 12 arranged opposite to each other. The first end plate 11 is fixed on the CNC integrated machine for processing wooden door frames. A first optical axis 13 is horizontally arranged between the first end plate 11 and the second end plate 12. The slide 41 passes through the first optical axis 13. The transverse component 2 is arranged on the outer side of the second end plate 12.

[0067] The second end plate 12 is provided with a shaft hole, and the transverse component 2 is a cylinder-driven structure or a servo-driven structure.

[0068] Specifically, the base 1 is a plate structure with perforated holes. The first end plate 11 and the second end plate 12 are fixed to both sides of the base 1 by bolts. The first end plate 11 is bolted onto the frame 100 of the CNC integrated machine to ensure the stability of the overall structure. The second end plate 12 is arranged parallel to the first end plate 11. Both the first optical axis 13 and the sliding axis 44 are equipped with linear bearings, which are installed in the corresponding holes of the slide block 41. A copper sleeve can be installed in the shaft hole of the second end plate 12 as a sliding bearing to reduce the coefficient of friction. In the cylinder drive structure, the cylinder is a standard SC series cylinder, with a stroke set to 300-600mm according to the door frame width specification. The output shaft is connected to the slide block 41 via a flange. In the servo drive structure, the ball screw lead is preferably 5mm, and the servo motor is equipped with an absolute encoder, with positioning accuracy controlled within 0.02mm.

[0069] Further, please refer to Figure 1 and Figure 2 The aforementioned cylinder drive structure includes a cylinder, the output shaft of which passes through a shaft hole and connects to the slide 41. The cylinder body is fixed to the outer side of the second end plate 12 by bolts. After the output shaft of the cylinder passes through the shaft hole of the second end plate 12, it forms a power transmission with the slide 41 through a threaded connection or key connection. Compressed air drives the cylinder piston rod to move linearly, which drives the slide 41 to move precisely along the first optical axis 13 through a rigid connection, driving the glue injection assembly 4 to enter the glue injection station or the avoidance station. As a preferred embodiment, the cylinder adopts a hydraulic buffer cylinder with a magnetic ring. At the end of the stroke, the position is detected by a magnetic switch. The air inlet of the cylinder is connected to the air source through a solenoid valve, thereby realizing the reciprocating motion control of the slide 41.

[0070] Furthermore, a compact, thin cylinder can be used to save installation space; the connection between the cylinder output shaft and the slide 41 can be a quick-release connector, thereby improving the ease of maintenance. Simultaneously, a speed control valve can be added to the cylinder's air supply circuit to adjust the movement speed of the slide 41.

[0071] In this embodiment, the slide block 41 is directly driven to move laterally by a cylinder, which features a simple and compact structure and high power transmission efficiency. Compared with servo drive structures, cylinder drive does not require complex transmission mechanisms and control systems, resulting in low maintenance costs and fast response speed.

[0072] Although cylinders have the characteristic of high power transmission efficiency, they cannot be matched with applications requiring high positioning accuracy. Therefore, this utility model further proposes that the transverse component 2 is a servo drive structure. Specifically, the servo drive structure (not shown) includes a servo motor and a ball screw; the ball screw includes a screw rod, a nut, and balls; the slide 41 is provided with a through hole for the screw rod to pass through, the output shaft of the servo motor is connected to one end of the screw rod, and the other end of the screw rod passes through the shaft hole and the through hole. The nut is fixed on the slide 41 and is coaxial with the through hole. The screw rod and the nut are in rolling contact through the balls. When the servo motor drives the screw rod to rotate, the nut drives the slide 41 to move laterally along the first optical axis 13.

[0073] Specifically, the servo motor serves as the power source, coaxially connected to the screw via a coupling. The screw is precision-ground, with a surface roughness controlled below Ra0.8 to ensure precise fit with the balls. The nut has internal circulating raceways, within which the balls form a closed-loop path. The diameter of the through-hole is larger than the outer diameter of the screw to prevent the screw from contacting the inner wall of the through-hole. A closed-loop control model with an encoder can be selected for the servo motor, with a position control accuracy set to 0.01mm.

[0074] In this embodiment, a servo motor drives a ball screw to achieve precise linear motion, solving the problem of insufficient positioning accuracy inherent in cylinder drives. Compared to cylinder drives, servo drives offer the following advantages: significantly improved position control accuracy, a wider speed adjustment range, and stepless speed regulation; shock-free motion, effectively reducing equipment vibration. Furthermore, encoder feedback enables closed-loop control, eliminating accumulated errors. The servo drive structure is particularly suitable for dispensing operations requiring precise positioning, ensuring that the dispensing rod 43 maintains a stable trajectory during lateral movement.

[0075] Furthermore, the aforementioned adjustment assembly 3 includes a mounting plate 31, a counter base 32, a counter 33, and an adjustment shaft 34;

[0076] The mounting plate 31 is located at the bottom of the slide 41 and is connected to the slide shaft 44. The counter seat 32 is mounted on the mounting plate 31, and the counter 33 is mounted on the counter seat 32. The adjusting shaft 34 passes through the counter seat 32, the counter 33 and the mounting plate 31 and is threadedly connected to the slide 41. The end of the adjusting shaft 34 is provided with a knob for fingers to hold.

[0077] Specifically, counter 33 can be a digital displacement counter used to detect the rotational displacement of adjusting shaft 34 in real time and convert it into the height adjustment amount of the glue injection assembly 4 for display. In a preferred embodiment, the adjusting shaft 34 and slide 41 can be connected by a precision threaded pair with a thread lead of 1mm, achieving a 1mm height adjustment per revolution. Counter 33 can be an encoder with a resolution of 0.01mm, calculating the displacement by detecting the rotation angle of adjusting shaft 34. The knob surface can be provided with anti-slip texture for easy gripping and force application by the operator. The mounting plate 31 and slide 44 can be connected by a key or pin to ensure reliable force transmission.

[0078] Furthermore, the aforementioned counter 33 is a digital displacement counter, whose detection end is connected to the adjustment shaft 34, and is used to detect the rotational displacement of the adjustment shaft 34 in real time and convert it into the height adjustment of the glue injection assembly 4 for display.

[0079] The digital displacement counter can use displacement sensors such as photoelectric encoders or magnetic scales to detect the rotational displacement. As a preferred embodiment, the photoelectric encoder calculates the displacement by detecting the pulse signal generated when the adjusting shaft 34 rotates, while the magnetic scale measures the displacement by reading the scale information on a magnetic ruler. Furthermore, the counter 33 can be equipped with an LCD screen to display the detected height adjustment amount digitally, facilitating real-time observation and adjustment by the operator.

[0080] In this embodiment, a digital displacement counter is used to accurately detect and visually display the height adjustment of the glue injection component 4. Compared with the traditional mechanical scale adjustment method, the digital display method avoids visual errors and improves adjustment accuracy. Simultaneously, the real-time display function allows operators to quickly and accurately grasp the current height position without repeated adjustments, thereby improving the operating efficiency and position control accuracy of the glue injection mechanism 104. This design is particularly suitable for wooden door frame processing scenarios that require frequent adjustments to the glue injection height, effectively solving the problems of low efficiency and poor accuracy of manual adjustment.

[0081] Furthermore, the aforementioned chip removal assembly 5 includes a connecting plate 51, an air blowing fixing seat 52, a first air blowing seat 53, and a second air blowing seat 54;

[0082] The connecting plate 51 is located on the top of the slide block 41 and is connected to the slide shaft 44. The air blowing fixing seat 52 and the glue injection seat 42 are arranged sequentially on the connecting plate 51 along the conveying direction of the plate 7.

[0083] The air-blowing fixing seat 52 has an air chamber. The first air-blowing seat 53 and the second air-blowing seat 54 are provided with air passages communicating with the air chamber. The first air-blowing seat 53 and the second air-blowing seat 54 are located at the top of the air-blowing fixing seat 52. The second air-blowing seat 54 is located between the first air-blowing seat 53 and the glue injection seat 42. The air-blowing direction of the first air-blowing seat 53 and the second air-blowing seat 54 is in the same direction as the axial direction of the glue dispensing rod 43.

[0084] The first air-blowing seat 53 is a plate-shaped structure, and the thickness of the first air-blowing seat 53 is the same as the diameter of the dispensing rod 43.

[0085] Specifically, the connecting plate 51 can be made of aluminum alloy to reduce weight, and it is fixedly connected to the sliding shaft 44 by bolts. The air chamber inside the air blowing base 52 is supplied with air from an external air source, and the air chamber can be designed as an annular channel to improve airflow uniformity. The air passages of the first air blowing base 53 and the second air blowing base 54 can be configured with an adjustable tilt angle to adapt to different processing requirements. The plate-like structure of the first air blowing base 53 can be made of stainless steel, and its thickness is precisely matched to the diameter of the glue dispensing rod 43 to ensure that the air blowing direction is parallel to the glue dispensing direction. The second air blowing base 54 can be configured as a detachable structure to facilitate position adjustment according to different plate widths 7. The connection between the air blowing base 52 and the connecting plate 51 can be a quick-release structure for easy maintenance and cleaning.

[0086] Furthermore, the glue injection mechanism also includes a pressure roller assembly 6, which includes several pressure roller mounting seats 61 and pressure rollers 62 rotatably connected to each pressure roller mounting seat 61. The pressure roller mounting seats 61 are fixed on the side of the first end plate 11 facing the second end plate 12. The pressure rollers 62 are located between the glue dispensing rod 43 and the slide 41, and the outer peripheral surface of the pressure rollers 62 rolls in contact with the lower surface of the plate 7. Specifically, the pressure roller mounting seats 61 can be made of metal casting or machined, and their mounting surfaces are provided with threaded holes for fixing to the first end plate 11 by bolts. The pressure rollers 62 are made of wear-resistant rubber material and are rotatably connected to the pressure roller mounting seats 61 through bearings. During the glue injection process, they provide stable rolling support for the plate 7. When the slide 41 drives the glue injection assembly 4 to move laterally, the pressure rollers 62 rotate with the plate 7, which not only avoids frictional damage between the plate 7 and the fixed support, but also effectively prevents the plate 7 from shifting or vibrating during the glue injection process.

[0087] In some embodiments, the dispensing assembly 4 includes a heat insulation cover that covers the dispensing base 42; the heat insulation cover is provided with an electric heating wire and a temperature sensor; and the dispensing rod 43 is a hollow ceramic electric heating tube.

[0088] The insulation cover is made of metal with a high-temperature resistant insulation layer on its inner wall. It is fixed to the top of the glue-filling base 42 by clips or bolts. Heating wires, made of nickel-chromium alloy, are evenly distributed on the inner top surface of the insulation cover and operate within a temperature range of 45-120℃. The temperature sensor is a PT100 platinum resistance thermometer, installed on the side wall of the insulation cover and extending into the glue-filling cavity. The outer diameter of the hollow ceramic heating tube matches the inner diameter of the glue outlet 45, and a spiral heating wire is built into the tube wall, connected to an external temperature control system via wires.

[0089] In this embodiment, the problem of poor glue dispensing caused by low-temperature solidification of the adhesive is solved by integrating a temperature control system. An insulation cover creates a closed thermal environment, which, combined with a ceramic electric heating element, achieves dual heating, ensuring the adhesive maintains a suitable viscosity during delivery. A temperature sensor provides real-time data feedback to the temperature control system, enabling precise temperature control and preventing equipment downtime for cleaning due to adhesive solidification.
