Description

Technical Field

[0001] This invention relates to the field of brazed saw blade production technology, and more specifically, to an automatic batch gluing device for the production process of brazed saw blades. Background Technology

[0002] Brazed saw blades are widely used for cutting hard and brittle materials such as stone, ceramics, and concrete. A crucial preliminary step in their production process is the pre-coating of the substrate surface with adhesive, which is used to bond cemented carbide in subsequent steps. The uniformity and thickness of the adhesive application, as well as the penetration effect of the adhesive into the grooves on the substrate surface, directly determine the adhesion strength of the cemented carbide and the final cutting performance and service life of the saw blade.

[0003] Currently, the gluing process in the production of brazed saw blades still largely relies on manual labor or semi-automatic equipment, which has the following significant drawbacks: Firstly, current methods mostly involve manually applying glue to each saw blade individually or using simple dip-dipping techniques, making it difficult to process multiple saw blades simultaneously in batches. Manual operation is limited by the operator's skill and condition, leading to fluctuations in the width and thickness of the glue layer between different saw blades, and even at different points along the circumference of the same saw blade. Simple dip-dipping devices, on the other hand, cause the glue level in the glue container to decrease as it is consumed, resulting in gradual changes in the glue width on saw blades processed sequentially, severely impacting product consistency and yield.

[0004] Secondly, the surface of the saw blade substrate often has fine grooves or pores. Under normal temperature and pressure coating conditions, the adhesive cannot fully penetrate into these microstructures, easily leaving air bubbles at the interface and forming coating defects. These defects will become weak points in the bond strength during subsequent brazing, causing the alloy layer to peel off or abnormal wear during cutting.

[0005] In addition, some existing equipment has a low degree of automation in saw blade transfer, installation and positioning, poor connection between workstations, and insufficient overall operational reliability, which hinders the continuous automated production of brazed saw blades from gluing to subsequent processes.

[0006] Therefore, it is necessary to improve existing technologies. Summary of the Invention

When the saw blade mounting shaft is placed on the support platform, it is horizontal and can rotate relative to the support platform. The lifting glue box is located between two support platforms at the glue application station. The upper end of the lifting glue box is open and connected to an oil supply mechanism. The rotary drive mechanism includes a pinion and a toothed belt. The toothed belt is mounted on the gluing frame via the drive mechanism. Each saw blade mounting shaft is equipped with a pinion. When the saw blade mounting shaft is located at the gluing station, the pinion at one end of the shaft meshes with the toothed belt. A retrieval robot used to move saw blade mounting shafts.

Bearings are provided on the opposite surfaces of the two clamping rods, and a clamping part that cooperates with the clamping rods is provided on the saw blade mounting shaft.

[0010] Preferably, the support platform includes a base and an arc-shaped groove disposed on the upper end of the base, and the placement structure includes a support bearing adapted to the size of the arc-shaped groove; The two arc-shaped grooves at the same workstation are provided with arc-shaped chamfers on the side that are close to each other, and the placement structure also includes a positioning ring that cooperates with the arc-shaped chamfers.

[0011] Preferably, it also includes a control module, wherein the feeding station is equipped with a sensor for detecting the presence of the saw blade mounting shaft, the sensor is signal-connected to the control module, and the control module is connected to a signal indicator light.

[0012] Preferably, the lifting glue box includes a glue box and a lifting drive mechanism for driving the glue box to move up and down; the oil supply mechanism includes a glue storage tank and a glue pump, with the glue inlet and outlet of the glue pump connected to the glue storage tank and the glue box, respectively.

[0013] Preferably, the glue box includes a working glue box, a glue application box, and a glue return box that are fixedly connected. The working glue box is provided with an overflow hole on the side near the glue return box, and the glue return box is connected to the glue storage tank through pipe I. The glue-applying box is connected to the glue pump via pipe II. A liquid level sensor is installed inside the glue-applying box. The working glue box has a glue inlet connected to the glue-applying box on the side near the glue-applying box, and the height of the glue inlet is higher than the overflow hole.

[0014] Preferably, a transducer is provided inside the plastic box, and the transducer is connected to an ultrasonic generator.

[0015] Preferably, a constant temperature jacket is provided on the outside of the glue storage tank; The loading station is equipped with a preheating module for preheating the brazed saw blade.

[0016] Preferably, the preheating module includes a constant temperature chamber, a temperature control module, and a heating module electrically connected to the temperature control module; The constant temperature chamber has an opening at the top, and a first sealing layer and a second sealing layer are arranged from top to bottom at the opening.

Both the first sealing layer and the second sealing layer include two elastic heat insulation films that are staggered.

[0018] The beneficial effects of this invention compared to the prior art are as follows: 1. This invention enables automated, continuous batch gluing of multiple saw blades. Saw blades are clamped in batches via a mounting shaft, and a robot automatically transfers parts between multiple workstations. Parallel operation at multiple workstations significantly increases production capacity.

[0019] 2. The rotary drive mechanism drives the saw blade mounting shaft to rotate at a uniform speed, ensuring that each saw blade makes full and uniform contact with the adhesive around its circumference; in conjunction with the ultrasonic transducer, micro-vibration is applied during the initial rotation to promote the penetration of the adhesive into the substrate grooves and micropores and eliminate interface bubbles, significantly enhancing the adhesion strength of the brazing alloy.

[0020] 3. The thermostatic jacket of the glue storage tank and the saw blade preheating module control the temperature matching between the glue and the substrate. The glue continuously circulates to prevent sedimentation and deterioration, maintaining the glue in its optimal process state. The saw blade mounting shaft achieves reliable pre-positioning through an arc groove and arc chamfer. The robotic arm uses a flexible gripping method with bearing contact to reduce the requirements for positioning accuracy, avoid rigid damage, and ensure long-term operational stability and reliability.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1:

[0026] like Figures 1 to 7As shown, an automatic batch gluing device for the production of brazed saw blades includes a gluing frame 1, a saw blade mounting shaft 3, a lifting glue box 4, an oil supply mechanism 5, a rotary drive mechanism 6, a picking robot 7, and a control module 8. The gluing frame 1 serves as the mounting base for the gluing process and supports other equipment. The gluing frame 1 is sequentially equipped with a feeding station 11 and several spaced-apart gluing stations 12. The feeding station 11 is used to temporarily hold the saw blade mounting shaft 3 and pre-position it for easy retrieval by the picking robot 7. The number of gluing stations 12 can be set according to process requirements; in this embodiment, three gluing stations 12 are provided. Both the feeding station 11 and the gluing station 12 include two support platforms 2 fixedly connected to the gluing frame 1. Each support platform 2 includes a base 21 and an arc-shaped groove 22 located on the upper end of the base 21. The two arc-shaped grooves 22 at the same station have arc-shaped chamfers 23 on their adjacent sides. The arc groove 22 is used for radial positioning of the saw blade mounting shaft 3, and the arc chamfer 23 is used for axial positioning of the saw blade mounting shaft 3.

[0027] When applying glue, the saw blade is mounted on the saw blade mounting shaft 3 and rotates or is moved synchronously with the saw blade mounting shaft 3. Specifically, the middle part of the saw blade mounting shaft 3 is used to place saw blades in batches. The saw blades are spaced apart, and adjacent saw blades can be limited by spacers. The saw blade mounting shaft 3 is provided with a saw blade clamping structure. For example, the saw blades can be clamped at both ends of the saw blade mounting shaft 3 by stepped shafts and fasteners.

[0028] To reliably place the saw blade mounting shaft 3 on the loading station 11 or the gluing station 12, both ends of the saw blade mounting shaft 3 are provided with placement structures 31 that cooperate with the support platform 2. Specifically, the placement structure 31 includes a support bearing adapted to the size of the arc-shaped groove 22 and a positioning ring that cooperates with the arc-shaped chamfer 23. When the saw blade mounting shaft 3 is placed on the support platform 2, the saw blade mounting shaft 3 is in a horizontal state, and the support bearing cooperates with the arc-shaped groove 22, allowing the saw blade mounting shaft 3 and the saw blade on it to rotate relative to the support platform 2.

[0029] When the saw blade mounting shaft 3 is transported from the loading station 11 to the gluing station 12 by the part picking robot 7, the saw blade mounting shaft 3 moves away from or near the support table 2 in the vertical direction. By setting the arc chamfer 23, when the saw blade mounting shaft 3 is close to the support table 2, the positioning ring and the arc chamfer 23 cooperate to achieve axial positioning and limiting.

[0030] The lifting glue box 4 is located between the two support platforms 2 of the glue application station 12. The lifting glue box 4 can be raised to make the glue surface contact the saw blade on the glue application station 12. The contact height (i.e., the glue application width on the saw blade) can be controlled by controlling the lifting height of the lifting glue box 4. The upper end of the lifting glue box 4 is open and connected to the oil supply mechanism 5.

[0031] Preferably, the lifting glue box 4 includes a glue box 41 and a lifting drive mechanism 42 for driving the glue box 41 to move up and down. The lifting drive mechanism 42 adopts an existing mechanism that needs to meet the requirements of low speed, high stability and positioning, such as linear motor drive, hydraulic drive or servo / stepper motor with lead screw drive.

[0032] The oil supply mechanism 5 includes a glue storage tank 51 and a glue pump 52. The glue inlet and glue outlet of the glue pump 52 are connected to the glue storage tank 51 and the glue box 41, respectively, and are used to supply oil to the glue box 41.

[0033] When the saw blade mounting shaft 3 is located at the glue application station 12, the saw blade needs to be driven to rotate by the rotary drive mechanism 6 so that the saw blade is in contact with the glue in the circumferential direction.

[0034] Specifically, the rotary drive mechanism 6 includes a pinion 61 and a toothed belt 62. The toothed belt 62 is mounted on the gluing frame 1 via the drive mechanism. The drive mechanism can use two support gears that mesh with both ends of the toothed belt 62 and support the toothed belt 62. A drive motor drives one of the support gears to rotate, thereby rotating the toothed belt 62. The toothed belt 62 needs to be driven at a very low speed. Preferably, the drive motor is a servo motor or a stepper motor. Each saw blade mounting shaft 3 is equipped with a pinion 61. When the saw blade mounting shaft 3 is located at the gluing station 12, the pinion 61 at one end meshes with the toothed belt 62, thereby driving the pinion 61 and the saw blade mounting shaft 3 (saw blade) to rotate at a low speed via the toothed belt 62.

[0035] The picking robot 7 is used to transport the saw blade mounting shaft 3. The picking robot 7 includes two robotic arms 71 and a robotic hand 72 located at the end of the robotic arms 71. The robotic arms 71 adopt existing robotic arms, which must include at least one horizontal degree of freedom and one vertical degree of freedom, so that the robotic hand 72 at the end of the robotic arms 71 can grasp and place the saw blade mounting shaft 3 in the vertical direction and can be translated to another work station.

[0036] The robotic arm 72 includes two synchronously moving, counter-moving grippers (existing general-purpose robotic arms can be used). Bearings 73 are provided on the opposing surfaces of the two grippers. A clamping part 32 that cooperates with the grippers is provided on the saw blade mounting shaft 3. When the grippers clamp the saw blade mounting shaft 3, the clamping part 32 contacts the bearings 73, which can reduce the positioning accuracy requirements of the robotic arm 72 when gripping, and also avoid the robotic arm 72 rigidly clamping the saw blade mounting shaft 3.

[0037] In this embodiment, the loading station 11 and the gluing station 12 are fixed at the position of the gluing frame 1. Therefore, the picking robot 7 can transport the saw blade mounting shaft 3 according to the set process flow and position coordinates.

[0038] Preferably, a visual recognition component can also be installed on the picking robot 7, so that the picking robot 7 can determine the position of the saw blade mounting shaft 3 and carry it out.

[0039] Working principle: S1. In the initial state, the saw blade mounting shaft 3 is located at the feeding station 11, the three glue application stations 12 are in an idle state, and the lifting glue box 4 is in a low position.

[0040] S2. Start the rotary drive mechanism 6 and the oil supply mechanism 5 to make the toothed belt 62 move at a constant speed and the glue level in the glue box 41 reach the set height.

[0041] S3. The picking robot 7 moves horizontally to above the loading station 11 and grabs the saw blade mounting shaft 3 on the loading station 11 in the vertical direction; then it moves horizontally to above one of the gluing stations 12 and places the saw blade mounting shaft 3 on the gluing station 12 in the vertical direction. At the same time as the saw blade mounting shaft 3 is placed, the small gear 61 at one end of it meshes with the toothed belt 62.

[0042] S4. The lifting glue box 4 corresponding to the gluing station 12 rises to the set position to apply glue to the rotating saw blade.

[0043] S5. Repeat the above steps so that saw blade mounting shafts 3 are placed in all three gluing stations 12 (the loading station 11 can be replenished manually or by a separately set robotic arm). After the saw blades on the saw blade mounting shafts 3 are glued, they are moved to the next process by the picking robot 7 (the next process should be equipped with a positioning receiving device).

[0044] S6. Repeat S3 and S4 above for the idle gluing station 12.

[0045] In this embodiment, the control module 8 is used to control the operation and process of the gluing device. Preferably, the control module 8 can be a PLC controller. The driving components involved in the gluing device are connected to the PLC controller through a circuit and controlled by the PLC controller.

[0046] The loading station 11 is equipped with a sensor 81 that detects the presence of the saw blade mounting shaft 3. The sensor 81 is connected to the control module 8, which is connected to an indicator light 82. When the sensor 81 detects that the loading station 11 is in an idle state, the control module 8 controls the corresponding indicator light 82 to send a signal to notify the operator to replenish the material.

[0047] Example 2:

[0048] like Figure 8As shown, based on Example 1, in order to improve the gluing effect, in this example, the glue box 41 includes a working glue box 411, a gluing glue box 412 and a return glue box 413 that are fixedly connected. The working glue box 411 is provided with an overflow hole 414 on the side near the return glue box 413. The return glue box 413 is connected to the glue storage tank 51 through pipe I. The liquid level in the working glue box 411 is controlled by the overflow hole 414, so that the gluing width of the saw blade is more accurate.

[0049] The glue application box 412 is connected to the glue pump 52 through pipe II. A liquid level sensor is installed inside the glue application box 412. The working glue box 411 is provided with a glue inlet 415 connected to the glue application box 412 on the side near the glue application box 412, and the height of the glue inlet 415 is higher than the overflow hole 414.

[0050] The glue pump 52 pumps glue from the glue storage tank 51 to the glue box 412. The liquid level sensor controls the liquid level in the glue box 412 to always be higher than the glue inlet 415, so that the glue box 412 always delivers glue to the working glue box 411 and prevents the liquid level in the working glue box 411 from dropping.

[0051] Preferably, a reflux hole is provided at the bottom of the working glue box 411 near the return glue box 413, and the flow rate of the reflux hole is much smaller than the flow rate of the glue inlet 415, so that the glue in the working glue box 411 is always in a circulating state, preventing the glue from deteriorating. A filter screen is provided between the return glue box 413 and the glue storage tank 51 to prevent impurities from entering the glue storage tank 51.

[0052] Preferably, a transducer is installed inside the glue box 41, and the transducer is connected to an ultrasonic generator. Ultrasonic vibration promotes the penetration of the glue into the grooves and pores on the saw blade surface, eliminating air bubbles. The ultrasonic generator is only activated during the first rotation of the saw blade to avoid adversely affecting the glue already applied to the saw blade.

[0053] Example 3:

[0054] Based on Example 1 or Example 2, to further improve the adhesive application effect, a temperature-controlled jacket is provided on the outside of the adhesive storage tank 51 to keep the adhesive inside the storage tank 51 within the optimal adhesive application temperature range. For example... Figure 9 , Figure 10 As shown, the loading station 11 is equipped with a preheating module 9 for preheating the saw blade. Preheating the saw blade prevents excessive temperature difference between the saw blade and the glue. A minimum preheating time can be set; if the saw blade on the saw blade mounting shaft 3 has not reached the preheating time, the picking robot 7 will not pick up the part from the saw blade mounting shaft 3.

[0055] In this embodiment, the preheating module 9 includes a constant temperature chamber, a temperature control module, and a heating module electrically connected to the temperature control module. The temperature control module, the heating module, and the temperature control logic all adopt existing mature control schemes. For example, the heating module includes an electric heating wire installed on the constant temperature chamber, and the temperature control module includes a controller and a temperature sensor and a circulating fan installed inside the constant temperature chamber.

[0056] An opening is provided at the top of the constant temperature chamber to control the insertion or removal of the saw blade mounting shaft 3. A first sealing layer 91 and a second sealing layer 92 are arranged sequentially from top to bottom at the opening. The distance between the first sealing layer 91 and the second sealing layer 92 is greater than the diameter of the saw blade to prevent the constant temperature chamber from being exposed during the insertion or removal of the saw blade mounting shaft 3.

[0057] Preferably, both the first sealing layer 91 and the second sealing layer 92 include two staggered elastic heat insulation films. The constant temperature chamber has two U-shaped frames 93 with opposite openings at positions corresponding to the first sealing layer 91 and the second sealing layer 92. The elastic heat insulation films are placed on the U-shaped frames 93, and one end of the two staggered U-shaped frames 93 is an elastic structure 94. When the saw blade mounting shaft 3 is placed or removed, the elastic structure 94 will not rigidly obstruct the saw blade mounting shaft 3. The side wall of the constant temperature chamber has a vertical slot 95 through which the saw blade mounting shaft can pass. Staggered elastic heat insulation films are provided on both sides of the vertical slot 95, and rebound strips are provided on the elastic heat insulation films to minimize heat loss from the constant temperature chamber.

[0058] The above description only illustrates the preferred embodiments of the present invention. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention, and all such changes should be included within the protection scope of the present invention.
