[0012] This utility model proposes an automatic dispensing equipment 1000, which is suitable for dispensing materials such as PCB boards, especially for PCB boards with many electronic components. It can complete the dispensing task efficiently and accurately, and is widely used in the field of electronic manufacturing.

[0013] Please see Figures 1 to 3In one embodiment of this utility model, the automatic dispensing equipment 1000 includes a conveying device 1, an amplitude adjustment and positioning device 2, a dispensing device 3, and a control module. The conveying device 1 includes a first frame 11 and a conveying mechanism 12. The first frame 11 is equipped with a camera module, and the conveying mechanism 12 is used to convey the material to be dispensed. The amplitude adjustment and positioning device 2 includes a second frame 25, a first translation mechanism 21, a second translation mechanism 22, a lifting and rotating mechanism 23, and a rotation adjustment mechanism 24 connected in sequence. The first translation mechanism 21 is configured to drive the second translation mechanism 22 to move along a first direction, and the second translation mechanism 22 is configured to... The lifting and rotating mechanism 23 is driven to move along the second direction. The lifting and rotating mechanism 23 is configured to drive the rotation adjustment mechanism 24 to move along the third direction and rotate around the third direction. The rotation adjustment mechanism 24 is configured to rotate around the fourth direction. The first direction, the second direction, and the third direction are arranged in pairs, and the fourth direction is arranged in pairs with the third direction. The dispensing device 3 is located on the rotation adjustment mechanism 24 and is arranged towards the conveying mechanism 12. The conveying mechanism 12, the camera module, the first translation mechanism 21, the second translation mechanism 22, the lifting and rotating mechanism 23, the rotation adjustment mechanism 24, and the dispensing device 3 are all communicatively connected to the control module.

[0014] In this embodiment, the conveying device 1 includes a first frame 11 and a conveying mechanism 12. The first frame 11 serves as a support structure and is equipped with a camera module (not shown in the attached figure) for real-time monitoring of the material to be dispensed and the position and status of the amplitude adjustment positioning device 2. The camera module includes a camera, circuitry, etc., and its specific configuration can refer to relevant solutions in the existing camera field, which will not be elaborated here. The conveying mechanism 12 is used to convey the material to be dispensed. Its structure can adopt a conveyor belt or roller conveyor, and the appropriate conveying speed and size can be selected according to actual production needs. The selection of the conveying mechanism 12 mainly considers factors such as the size and weight of the material and the production cycle to ensure that the material can be stably and continuously conveyed to the dispensing position.

[0015] The amplitude adjustment positioning device 2 includes a second frame 25, a first translation mechanism 21, a second translation mechanism 22, a lifting and rotating mechanism 23, and a rotation adjustment mechanism 24 connected in sequence. The first translation mechanism 21 is configured to drive the second translation mechanism 22 to move along a first direction. Its structure can employ a linear motor or lead screw drive, providing high precision and stability. The second translation mechanism 22 is configured to drive the lifting and rotating mechanism 23 to move along a second direction. It can also employ a similar transmission method to the first translation mechanism 21 and cooperate with it to achieve position adjustment in a two-dimensional plane. The lifting and rotating mechanism 23 is configured to drive the rotation adjustment mechanism 24 to move along a third direction and rotate around that direction. Optionally, its structure can include a lifting cylinder and a rotary motor. By precisely controlling the extension and retraction of the cylinder and the rotation speed of the motor, the vertical position adjustment and rotation of the dispensing device 3 are achieved. The rotation adjustment mechanism 24 is configured to rotate around a fourth direction, further increasing the flexibility of the dispensing device 3. Its structure can employ a high-precision rotary joint to ensure smooth and accurate rotation. The first, second, and third directions are arranged in pairs, and the fourth direction is arranged in pairs with the third direction. This layout allows the amplitude adjustment positioning device 2 to achieve five degrees of freedom of movement in three-dimensional space, flexibly adapting to dispensing needs at different positions and angles. Preferably, a three-dimensional Cartesian coordinate system can be referenced, with the first direction coinciding with the X-axis, the second direction coinciding with the Y-axis, and the third direction coinciding with the Z-axis. Thus, the first translation mechanism 21 is configured to drive the second translation mechanism 22 to move linearly along the X-axis. The second translation mechanism 22 is configured to drive the lifting and rotating mechanism 23 to move linearly along the Y-axis. Combined with the X-axis movement of the first translation mechanism 21, the dispensing device 3 can perform two-dimensional position adjustment in the XY plane, accurately locating the specific position of the material to be dispensed in the XY plane, providing an accurate spatial position basis for subsequent dispensing operations. The movement of the lifting and rotating mechanism 23 includes two parts: movement along the Z-axis and rotation around the Z-axis. The lifting component of the lifting and rotating mechanism 23, such as a lifting cylinder, under the control of the control module, enables the rotation adjustment mechanism 24 to rise or fall along the Z-axis. This Z-axis movement is primarily for adjusting the height of the dispensing device 3, allowing it to adapt to materials of different heights to be dispensed, or for adjusting the distance between the dispensing head and the material surface as needed during the dispensing process, thus ensuring the quality and accuracy of the dispensing. The rotating component of the lifting and rotating mechanism 23, such as a rotary motor, can drive the rotation adjustment mechanism 24 to rotate around the Z-axis. This rotational motion around the Z-axis allows the dispensing device 3 to change direction on the horizontal plane, enabling dispensing of electronic components in different orientations on the material, further increasing the flexibility and adaptability of the dispensing device 3, and enabling it to better meet the dispensing needs of complex materials.The rotation adjustment mechanism 24 is configured to rotate about a direction perpendicular to the Z-axis, i.e., the fourth direction is perpendicular to the Z-axis. It should be noted that as the rotating part of the lifting and rotating mechanism 23 rotates about the Z-axis, the fourth direction changes, but it remains perpendicular to the A-axis. That is, the fourth direction can be any direction perpendicular to the Z-axis; for example, the rotation adjustment mechanism 24 can be configured to rotate about the X-axis. This allows the dispensing device 3 to achieve flexible and varied movement in three-dimensional space, adapting to various complex spatial positions and angular requirements, greatly improving the versatility and practicality of the dispensing equipment.

[0016] The dispensing device 3 is located on the rotation adjustment mechanism 24 and faces the conveying mechanism 12. Its structure can adopt a glue valve type dispensing head, which gradually squeezes out the glue through a pneumatic piston, and has high-precision flow control and stable dispensing performance. The selection of the dispensing device 3 mainly considers factors such as the viscosity of the glue, the amount of glue dispensed, and the dispensing frequency to ensure that it can meet the dispensing requirements of different materials.

[0017] The conveying mechanism 12, camera module, first translation mechanism 21, second translation mechanism 22, lifting and rotating mechanism 23, rotation adjustment mechanism 24, and dispensing device 3 are all communicatively connected to the control module, for example, directly via wires or by setting up radio frequency signal transmitting and receiving devices. The control module can be a PLC or industrial computer, or other modules with data processing and control capabilities. Based on the information identified in real time by the camera module, the control module precisely controls the movement of the amplitude modulation positioning device 2 through a preset algorithm and control program, driving the dispensing device 3 to approach the position on the material to be dispensed and perform the dispensing operation.

[0018] In summary, this embodiment uses a camera module to identify the position and state of the material to be dispensed in real time, and a control module to precisely control the movement of the amplitude adjustment and positioning device 2, thereby achieving precise positioning and flexible adjustment of the dispensing device 3 in three-dimensional space to complete the dispensing operation. This effectively solves the problems of low efficiency and large quality fluctuations in traditional manual dispensing, improving both dispensing efficiency and uniformity.

[0019] Further, please refer to Figures 3 to 5In one embodiment of this utility model, the first translation mechanism 21 includes a first base 211, a first motor 212, a limiting member 213, a first lead screw 214, and a first slider 215. The first base 211 is connected to the second frame 25. The first motor 212 is disposed on the first base 211 and is communicatively connected to the control module. The limiting member 213 is fixedly connected to the first base 211. The first lead screw 214 extends along a first direction and is rotatably connected to the limiting member 213 and is drively connected to the first motor 212. A first threaded hole is formed on the first slider 215. The first lead screw 214 passes through the first threaded hole and is screwed to the inner wall of the first threaded hole. The second translation mechanism 22 is connected to the first slider 215.

[0020] In this embodiment, the first base 211 is a supporting component of the first translation mechanism 21, connected to the second frame 25, serving to fix and support the entire first translation mechanism 21. The first base 211 can be made of high-strength metal material to ensure sufficient rigidity and stability, capable of withstanding the weight of components such as the first motor 212 and the first lead screw 214, as well as various forces generated during movement. The first motor 212 is mounted on the first base 211 and is communicatively connected to the control module. The first motor 212 is the power source of the first translation mechanism 21, responsible for driving the rotation of the first lead screw 214. The limiting member 213 is fixedly connected to the first base 211, and its function is to limit the axial movement of the first lead screw 214, ensuring that the first lead screw 214 can rotate stably within the first base 211. The limiting member 213 can be a bearing and a bearing housing. The bearing can withstand not only radial force but also a certain axial force, thereby ensuring the rotational accuracy and stability of the first lead screw 214. In addition, the limiting component 213 can also play a certain supporting role, reducing the vibration and shaking of the first lead screw 214 during operation and improving the overall stability of the mechanism.

[0021] The first lead screw 214 extends along a first direction, which can be the X-axis direction. The first lead screw 214 can be fixed to the first base by two limiting members 213. One end of the first lead screw 214 is connected to the first motor 212 for transmission. The output shaft of the first motor 212 can be connected to one end of the first lead screw 214 by a coupling or other components to ensure accurate and reliable power transmission between the two.

[0022] A first threaded hole is formed on the first slider 215, and a first lead screw 214 passes through the first threaded hole and is screwed to the inner wall of the first threaded hole. Driven by the first lead screw 214, the first slider 215 moves linearly along a first direction. The cooperation between the first slider 215 and the first lead screw 214 ensures the smoothness and accuracy of the movement. The first slider 215 is directly or indirectly connected to the second translation mechanism 22. When the control module issues a movement command, the first motor 212 starts to rotate according to the command. Since the first motor 212 is driven by the first lead screw 214, the first lead screw 214 rotates with the first motor 212. The rotation of the first lead screw 214, through its screwed connection with the first threaded hole on the first slider 215, converts the rotational motion into linear motion of the first slider 215 along the first direction. The movement of the first slider 215 drives the second translation mechanism 22 connected to it to move along the X-axis direction, thereby realizing the position adjustment of the dispensing device 3 in the X-axis direction.

[0023] Further, please refer to Figure 5 In one embodiment of the present invention, the first translation mechanism 21 further includes a guide block 216 and a first guide rail 217; the guide block 216 is disposed on the first slider 215, and a first guide groove is formed on the guide block 216; the first guide rail 217 is disposed on the first base 211 and extends along the first direction, and the first guide rail 217 is slidably connected to the inner wall of the first guide groove.

[0024] In this embodiment, the main function of the guide block 216 is to provide guidance and support for the movement of the first slider 215. A first guide groove is formed on the guide block 216, the shape and size of which match the first guide rail 217, ensuring that the first slider 215 can move smoothly and accurately along the first guide rail 217. The guide block 216 can be made of high-strength, wear-resistant materials to ensure that it maintains good performance and accuracy during long-term use. The guide block can be connected and fixed to the first slider 215 by fasteners such as screws or by welding. The first guide rail 217 is disposed on the first base 211 and extends along a first direction; its main function is to provide guidance and constraint for the movement of the first slider 215. The combined use of the guide block 216 and the first guide rail 217 can significantly improve the movement accuracy and stability of the first slider 215. The first guide rail 217 provides precise guidance for the movement of the first slider 215, ensuring that the first slider 215 always stays on the predetermined trajectory during movement, avoiding inaccurate positioning due to movement deviation. For example, during the dispensing process, if precise dispensing is required for multiple adjacent electronic components, the high-precision cooperation between the guide block 216 and the first guide rail 217 ensures that the dispensing device 3 can accurately reach the target position. The first guide rail 217 also supports and constrains the first slider 215, reducing vibration and swaying of the first slider 215 during movement and avoiding dispensing position deviation caused by vibration and swaying.

[0025] Further, please refer to Figure 3 and Figure 6 In one embodiment of this utility model, the second translation mechanism 22 includes a second base 221, a second motor 222, a second lead screw 223, a second slider 224, and a first adapter 225. The second base 221 includes an upper body 2211 and a lower body 2212 that are detachably connected to each other. The upper body 2211 is connected to the first translation mechanism 21. The upper body 2211 forms a limiting part 22111, and the lower body 2212 forms a second guide rail 22121 extending along a second direction. The second motor 222 is located at... The upper body 2211 is communicatively connected to the control module; the second lead screw 223 extends along the second direction, and is rotatably connected to the limiting part 22111 and is driven by the second motor 222; the second slider 224 has a second thread hole and a second guide groove 224a, the second lead screw 223 passes through the second thread hole and is screwed to the inner wall of the second thread hole, and the second guide rail 22121 is slidably connected to the inner wall of the second guide groove 224a; the first adapter 225 connects the second slider 224 and the lifting and rotating mechanism 23.

[0026] In this embodiment, the second base 221 is a supporting component of the second translation mechanism 22, consisting of an upper base 2211 and a lower base 2212 that are detachably connected to each other. This detachable connection facilitates installation, debugging, and maintenance, improving the flexibility and maintainability of the equipment. Optionally, the detachable connection can be achieved by fasteners such as bolts or by providing mutually cooperating mechanical buckles on the upper base 2211 and the lower base 2212 respectively. The lower base 2212 is connected to the first slider 215 by fasteners such as bolts or by welding, transmitting the power of the first translation mechanism 21 to the second translation mechanism 22. The upper base 2211 forms a limiting part 22111 for supporting and limiting the axial movement of the second lead screw 223. The lower base 2212 forms a second guide rail 22121 extending along a second direction, providing guidance and constraint for the movement of the second slider 224. One end of the upper body 2211 is provided with a mounting frame, and the second motor 222 is located inside the mounting frame of the upper body 2211 and is communicatively connected to the control module. The second motor 222 is the power source of the second translation mechanism 22 and is responsible for driving the second lead screw 223 to rotate.

[0027] The second lead screw 223 extends along the second direction. A limiting part 22111 is formed at both ends of the upper body 2211. A bearing can be installed in the limiting part 22111 to connect with the second lead screw 223. The second lead screw 223 can be fixed to the first base through the limiting parts 22111 at both ends of the upper body 2211 and its rotation is not affected. One end of the second lead screw 223 is connected to the second motor 222 for transmission. A coupling or other components can be used to connect the output shaft of the second motor 222 to one end of the second lead screw 223 to ensure accurate and reliable power transmission between the two.

[0028] The second slider 224 has a second threaded hole and a second guide groove 224a. The second lead screw 223 passes through the second threaded hole and is screwed to the inner wall of the second threaded hole. Through the screwed connection, the rotational motion of the second lead screw 223 is converted into the linear motion of the second slider 224 along the second direction. The second guide groove 224a is slidably connected to the second guide rail 22121 on the lower seat 2212, providing guidance and constraint for the movement of the second slider 224, ensuring the stability and accuracy of the second slider 224 during the movement.

[0029] The bottom wall of the first adapter 225 is connected to the second slider 224, and the side wall of the first adapter 225 is connected to the lifting and rotating mechanism 23. Since the extension direction of the lifting and rotating mechanism 23 is different from that of the second translation mechanism 22, the bottom wall and the side wall of the first adapter 225 are designed with a specific angle to accommodate the difference between the extension direction of the lifting and rotating mechanism 23 and the extension direction of the second translation mechanism 22, for example, a 90° angle design.

[0030] When the control module issues a motion command, the second motor 222 begins to rotate accordingly. Since the second motor 222 is connected to the second lead screw 223, the second lead screw 223 rotates accordingly. The rotation of the second lead screw 223, through its screw connection with the second threaded hole on the second slider 224, converts the rotational motion into linear motion of the second slider 224 along the second direction. The movement of the second slider 224 drives the first adapter 225 connected to it, which in turn drives the lifting and rotating mechanism 23 to move along the Y-axis direction, thereby realizing the position adjustment of the amplitude adjustment positioning device 2 in the Y-axis direction.

[0031] Further, please refer to Figures 7 to 8In one embodiment of this utility model, the lifting and rotating mechanism 23 includes a third base 231, a third lead screw 232, a first rotating sleeve 233, a second rotating sleeve 234, a third motor 235, and a fourth motor 236. The third base 231 is connected to the second translation mechanism 22. The third lead screw 232 is movably inserted through the third base 231 and extends along a third direction. The outer wall of the third lead screw 232 is provided with a drive groove 232a extending along a third direction. The first rotating sleeve 233 is rotatably connected to the third base 231, and the first rotating sleeve 233 forms a third motor 236. The third lead screw 232 passes through the third lead screw hole and is screwed to the inner wall of the third lead screw hole; the second rotating sleeve 234 is rotatably connected to the third base 231, and a clearance hole is formed on the second rotating sleeve 234. A driving protrusion is provided on the inner wall of the clearance hole. The third lead screw 232 passes through the clearance hole, and the driving protrusion extends into the driving groove 232a and is slidably connected to the inner wall of the driving groove 232a; the third motor 235 is drivenly connected to the first rotating sleeve 233 and is communicatively connected to the control module; the fourth motor 236 is drivenly connected to the second rotating sleeve 234 and is communicatively connected to the control module.

[0032] In this embodiment, the third base 231 is a supporting component of the lifting and rotating mechanism 23, connected to the second slider 224, and serves to fix and support the entire lifting and rotating mechanism 23. The third base 231 can be made of high-strength metal material to ensure that it has sufficient rigidity and stability to withstand the weight of components such as the third lead screw 232 and the motor, as well as various forces generated during movement. The third lead screw 232 is movably inserted into the third base 231 and extends along a third direction. The outer wall of the third lead screw 232 is provided with a drive groove 232a extending along a third direction for engaging with a drive protrusion (not shown in the figure) on the second rotating sleeve 234.

[0033] The first rotating sleeve 233 is rotatably connected to the third base 231, forming a third threaded hole. The third lead screw 232 passes through the third threaded hole and is screwed to the inner wall of the third threaded hole. The first rotating sleeve 233 is driven by the third motor 235, receiving power from the third motor 235 to drive the third lead screw 232 to move up and down along the Z-axis. The second rotating sleeve 234 is rotatably connected to the third base 231, and a clearance hole is formed on the second rotating sleeve 234. A driving protrusion is provided on the inner wall of the clearance hole. The third lead screw 232 passes through the clearance hole, and the driving protrusion extends into the driving groove 232a and slides in connection with the inner wall of the driving groove 232a. The second rotating sleeve 234 is driven by the fourth motor 236, receiving power from the fourth motor 236, and drives the third lead screw 232 to rotate around the Z-axis through the mechanical cooperation between the driving protrusion and the driving groove 232a.

[0034] The third motor 235 is driven by the first rotating sleeve 233 and communicates with the control module. The third motor 235 is the main power source for the lifting function, driving the first rotating sleeve 233 to rotate, thereby causing the third lead screw 232 to move up and down along the Z-axis. The fourth motor 236 is driven by the second rotating sleeve 234 and communicates with the control module. Both the fourth motor 236 and the third motor 235 provide power for the rotation function, driving the second rotating sleeve 234 to rotate, thereby causing the third lead screw 232 to rotate around the Z-axis.

[0035] It should be noted that when the third motor 235 is started but the fourth motor 236 is locked, the second rotating sleeve 234 is locked, and the first rotating sleeve 233 rotates and drives the third lead screw 232. Since the driving protrusion is slidably connected to the inner wall of the driving groove 232a, the third lead screw 232 does not rotate but only slides up and down along the third axis to achieve lifting and lowering. At this time, both the first rotating sleeve 233 and the second rotating sleeve 234 slide relative to the third lead screw 232. This movement mode allows the dispensing device 3 to be adjusted up and down in the Z-axis direction to accommodate materials of different heights or to adjust the distance between the dispensing head and the material surface, ensuring the quality and accuracy of dispensing. When both the third motor 235 and the fourth motor 236 are started, they can drive the first rotating sleeve 233 and the second rotating sleeve 234 to rotate synchronously in the same direction. At this time, both the first rotating sleeve 233 and the second rotating sleeve 234 are stationary relative to the third lead screw 232, and the third lead screw 232 only rotates without lifting or lowering. This motion allows the dispensing device 3 to rotate and adjust around the Z-axis on the horizontal plane to adapt to dispensing needs at different angles, further improving the flexibility and adaptability of the dispensing device 3.

[0036] Further, please refer to Figure 7 and Figure 8 In one embodiment of this utility model, the lifting and rotating mechanism 23 further includes a first fixed sleeve 2371 and a first drive wheel 2372. The first drive wheel 2372 is rotatably sleeved outside the third lead screw 232 and fixedly connected to the first rotating sleeve 233. The first fixed sleeve 2371 is fixedly connected to the third base 231 and sleeved outside the first rotating sleeve 233. The first fixed sleeve 2371 and the first rotating sleeve 233 are rotatably connected. The first drive wheel 2372 is driven by the third motor 235. The lifting and rotating mechanism 23 also includes a second fixed sleeve 2381 and a second drive wheel 2382. The second drive wheel 2382 is rotatably sleeved outside the third lead screw 232 and fixedly connected to the second rotating sleeve 234. The second fixed sleeve 2381 is fixedly connected to the third base 231 and sleeved outside the second rotating sleeve 234. The first fixed sleeve 2371 and the second rotating sleeve 234 are rotatably connected. The second drive wheel 2382 is driven by the fourth motor 236.

[0037] In this embodiment, the first fixed sleeve 2371 is fixedly connected to the third base 231 and sleeved outside the first rotating sleeve 233. It serves to support and fix the first rotating sleeve 233, ensuring that the first rotating sleeve 233 can rotate stably within the third base 231. The first fixed sleeve 2371 is rotatably connected to the first rotating sleeve 233, allowing the first rotating sleeve 233 to rotate freely within the first fixed sleeve 2371. The first fixed sleeve 2371 can be fixed to the third base 231 with bolts. Since the rotation of the first fixed sleeve 2371 may cause wear to the components in contact with it, the first fixed sleeve 2371 is provided on the third base. The first fixed sleeve 2371 can be replaced after wear without replacing the entire third base 231. The first drive wheel 2372 is rotatably sleeved outside the third lead screw 232 and fixedly connected to the first rotating sleeve 233. The first drive wheel 2372 is connected to the third motor 235 via a transmission. The third motor 235 drives the first drive wheel 2372 to rotate, thereby causing the first rotating sleeve 233 to rotate. The first drive wheel 2372 can be a gear or a pulley. If a gear transmission is used, a gear can be installed on the drive shaft of the third motor 235 to mesh with the first drive wheel 2372; if a belt transmission is used, a pulley can be installed on the drive shaft of the third motor 235 and connected to the first drive wheel 2372 via a belt. Similarly, the second fixed sleeve 2381 and the second drive wheel 2382 can be described with reference to the first fixed sleeve 2371 and the first drive wheel 2372, and will not be described again.

[0038] Further, please refer to Figure 9 In one embodiment of the present invention, the rotation adjustment mechanism 24 includes a second adapter 243 and a fifth motor 245. The second adapter 243 connects the lifting and rotating mechanism 23 and the fifth motor 245. The drive shaft of the fifth motor 245 is arranged along the fourth direction and is communicatively connected to the control module. The fifth motor 245 is connected to the dispensing device 3 for transmission.

[0039] In this embodiment, the second adapter 243 connects the third lead screw 232 and the fifth motor 245. One part of the adapter is clamp-shaped for fixing to the third lead screw 232, while the other part is planar for bolt connection to the housing of the fifth motor 245. The drive shaft of the fifth motor 245 is arranged along the fourth direction and is communicatively connected to the control module. The fifth motor 245 is the power source for the rotation adjustment mechanism 24, responsible for driving the dispensing device 3 to rotate around the fourth direction.

[0040] Further, please refer to Figure 9In one embodiment of this utility model, the rotation adjustment mechanism 24 further includes a fourth base 241, a rotating drum 242, and a photoelectric sensing mechanism 244; the fourth base 241 is connected to the second adapter 243 and the fifth motor 245, and the rotating drum 242 is rotatably disposed on the fourth base 241 and is connected to the fifth motor 245 for transmission; the photoelectric sensing mechanism 244 includes a photoelectric gate 2441 and a blocking member 2442, the blocking member 2442 is disposed on the rotating drum 242, and the photoelectric gate 2441 is disposed on the fourth base 241 and located on the rotation path of the blocking member 2442; the dispensing device 3 is connected to the rotating drum 242.

[0041] In this embodiment, the fourth base 241 is a supporting component of the rotation adjustment mechanism 24, connecting the second adapter 243 and the fifth motor 245, and serving to fix and support the entire rotation adjustment mechanism 24. The fourth base 241 can be made of high-strength metal material to ensure that it has sufficient rigidity and stability to withstand the weight of components such as the rotating drum 242 and the fifth motor 245, as well as various forces generated during movement. The rotating drum 242 is rotatably mounted on the fourth base 241 and is connected to the fifth motor 245 for transmission. Specifically, one end of the rotating drum 242 is provided with a boss and a gear, and a gear cavity is formed in the fourth base. The end of the rotating drum 242 with the boss and gear is confined within the gear cavity. The drive shaft of the fifth motor 245 extends into the gear cavity, and another gear is provided on the drive shaft of the fifth motor 245 that meshes with the gear on the rotating drum 242.

[0042] The photoelectric sensing mechanism 244 includes a photoelectric gate 2441 and a blocking member 2442. The blocking member 2442 is located on the rotating drum 242 and rotates synchronously with the rotating drum 242. The photoelectric gate 2441 is located on the fourth base 241 and is situated on the rotation path of the blocking member 2442. The photoelectric gate 2441 is a photoelectric sensor, which emits a light signal at one end and receives it at the other end. When the blocking member 2442 rotates into the detection range of the photoelectric gate 2441, it blocks the light signal. At this time, the other end of the photoelectric gate 2441 cannot receive the light signal, indicating that the rotating drum 242 has rotated to the predetermined position. In this way, after resetting the dispensing device 3, confirmation can be performed to ensure that the dispensing device resets to the preset position each time.

[0043] Please see Figure 2 In one embodiment of the present invention, the second frame 25 includes a lower frame 251 and an upper cover 252 connected to each other. A protective cavity is formed inside the upper cover 252, and the amplitude adjustment positioning device 2 and the dispensing device 3 are disposed inside the protective cavity. The inner wall of the protective cavity is provided with a window 252a communicating with the external space. The window 252a is used for the amplitude adjustment positioning device 2 and the dispensing device 3 to pass through.

[0044] To provide an environment that protects internal components while ensuring normal equipment operation, the second frame 25 in this embodiment consists of a lower frame 251 and an upper cover 252, which are interconnected to form a complete frame structure. The upper cover 252 contains a protective cavity, the main function of which is to provide a protective space for the amplitude modulation positioning device 2 and the dispensing device 3. Furthermore, the window 252a can be configured to open and close, such as by incorporating a push-pull or rotating window mechanism. When the equipment is stopped, by placing these critical devices within the protective cavity and closing the window 252a, external dust, impurities, and other potential interference factors can be effectively prevented from adversely affecting equipment operation, thereby improving equipment stability and service life. Even when the window 252a is open during use, the upper cover 252 can prevent debris from falling in or personnel from accidentally impacting and damaging the internal devices.

[0045] Furthermore, in one embodiment of the present invention, an encoding wheel assembly is provided on the first frame 11. The encoding wheel assembly includes a mounting bracket and an encoding wheel body. The mounting bracket is connected to the first frame 11, and the encoding wheel body is connected to the conveying mechanism 12 for transmission and to the control module for communication.

[0046] In this embodiment, the mounting bracket is connected to the first frame 11 and serves to fix the main body of the coding wheel.

[0047] The encoder wheel body is drivenly connected to the conveyor belt or rollers of the conveyor mechanism 12 to measure the operating speed of the conveyor mechanism 12. The encoder wheel body consists of a rotating wheel and a photoelectric sensor. The wheel contacts the conveyor belt or rollers of the conveyor mechanism 12 and rotates as the conveyor mechanism 12 operates. The photoelectric sensor is used to detect the rotational speed of the encoder wheel, thereby indirectly measuring the operating speed of the conveyor mechanism 12.

[0048] The control module adjusts the movement speed of the amplitude-adjusting positioning device 2 and the dispensing frequency of the dispensing device 3 according to the conveying speed, ensuring that the dispensing device 3 can accurately dispense glue during material movement. This method of dispensing glue while conveying not only improves dispensing efficiency but also reduces material downtime, further enhancing production efficiency.

[0049] By measuring the conveyor speed in real time through the encoder wheel assembly, the control module can precisely control the movement of the dispensing mechanism, ensuring the accuracy of the dispensing position. This precise control effectively reduces dispensing position deviations caused by fluctuations in conveyor speed, improving dispensing accuracy and quality.

[0050] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
