[0002] In order to ensure the assembly of workpieces, it is inevitable to use adhesive materials. Dispensing refers to the operation process of applying fluid adhesive materials to the specified position of the target workpiece in the form of "point", "line" and "surface" by manual or special equipment. Dispensing operation is required in various industrial production and manufacturing scenarios: for example, in the electronic industry, the connector interface needs to be sealed by dispensing to improve the reliability of the connection; in the automotive manufacturing industry, the electronic components inside the car are dispensed for protection to adapt to the harsh environment of vibration or high temperature during driving; in medical devices, the sealing dispensing of medical devices such as syringes and infusion devices can ensure their sterility and safety. Moving iron core, sensor chip, electromagnetic valve core and other workpieces are common workpieces that need to be dispensed. The traditional dispensing process mainly uses manual dispensing and wiping of excess glue, which has the problems of difficult control of dispensing amount and uneven appearance cleanliness after wiping.

[0070] Thus, one feature that is described in the specification can be used to explain one embodiment of the application, and is not necessarily intended to be used to explain every embodiment of the application. Further, it will be appreciated that the specification describes numerous specific details that can be used to exemplify the application. While these details are described in the specification, they are not intended to limit the application to the details described herein. Thus, it will be appreciated that the description is intended to cover all alternatives, modifications and equivalents.

[0071] In the embodiments shown in the drawings, the indications of direction, such as up, down, left, right, front and rear, are used to explain the structure and movement of the various elements of the application are not absolute but relative. These indications are appropriate when the elements are in the position shown in the drawings. If the position of the elements is changed, the indications of direction are changed accordingly.

[0072] Referring to Figure 1 , Figure 2 , Figure 10 and Figure 12 , an embodiment of the application provides a dispensing machine mainly comprising a machine base 100, further comprising a conveying device, a dispensing device 3, a curing device 4 and a glue wiping and residual glue recycling device 5, the conveying device is provided with a plurality of workpiece carrying modules 1 distributed at equal intervals, the workpieces on the workpiece carrying modules 1 are conveyed to pass through the dispensing device 3, the curing device 4 and the glue wiping and residual glue recycling device 5 in turn; the dispensing device 3 and the curing device 4 are respectively used for workpiece gluing and curing the glue on the surface of the workpiece; the glue wiping and residual glue recycling device 5 comprises a glue wiping module 51, a first workpiece self-rotation driving module 52 and a residual glue recycling module 53; the glue wiping module comprises a linear wiping member 511, which is arranged to move along a preset path and wipe the workpiece assembly surface at a specified position in the preset path; the residual glue recycling module 53 is arranged at the terminal position of the wiping member moving path and is used for recycling residual glue and the linear wiping member 511.

[0073] The dispensing machine of the present application is suitable for workpieces that need to be dispensed, especially for workpieces with complex curved surfaces, such as workpieces with threads and slits on the surface. The dispensing machine of the present application adopts a linear wiping member 511, which can closely fit the complex curved surface of the workpiece, and the linear wiping member 511 is driven to rotate by the first workpiece self-rotation driving module 52, so that the linear wiping member 511 and the workpiece are in contact, and then the workpiece is continuously wiped without blind area, and the wiping effect is significantly improved. By setting the residual glue recovery module 53 for recovering residual glue and the linear wiping member 511, the wiping surface of the linear wiping member 511 can be updated in real time, the frequency of replacing the wiping member is significantly reduced, and since the linear wiping member 511 after wiping falls into the residual glue recovery module 53 together with the residual glue, the linear wiping member 511 does not need to be replaced during shutdown, and the production efficiency is improved. In addition, by setting the residual glue recovery module 53, the residual glue after wiping can also be recovered, and the recovered glue can be reused after filtration, reducing the waste of consumables.

[0074] In the present embodiment, the dispensing machine of the present application is used for dispensing between the moving iron core and the trip lever.

[0075] As a preferred embodiment, the conveying device is a rotary machine 10, and a plurality of workpiece carrying modules 1 are arranged at equal intervals on the rotary machine 10. The dispensing machine further comprises a feeding device 2 and a collecting device 6, and the feeding device 2, the dispensing device 3, the curing device 4, the wiping and residual glue recovery device 5, and the collecting device 6 are sequentially arranged on the outer periphery side of the rotary machine 10 along the rotation direction of the rotary machine 10. The feeding device 2 is used to place the workpieces to be dispensed on the workpiece carrying modules 1, and the collecting device 6 is used to collect the workpieces from the workpiece carrying modules 1. By arranging the devices in a ring around the rotary machine 10, the occupied area of the dispensing machine is reduced, and the space utilization is improved. In addition, the ring arrangement allows the plurality of workpiece carrying modules 1 of the rotary machine 10 to be in different stations at the same time, reduces the waiting time of the workpieces, and realizes continuous flow production.

[0076] Specifically, the rotary machine 10 comprises a rotating disc 101, a pneumatic cylinder 102 is arranged on the edge of the rotary machine 10, and a transmission assembly (not shown in the figure) connected to the pneumatic cylinder is arranged inside the rotary machine 10. The pneumatic cylinder 102 is used to drive the transmission assembly to rotate, and then drive the rotating disc 101 to rotate, so that the workpiece carrying modules 1 arranged on the rotary machine 10 pass through each station in turn to complete the dispensing work. It should be noted that the specific structure and cooperation mode of the rotating disc 101, the pneumatic cylinder 102, and the transmission assembly of the rotary machine 10 belong to the prior art, and will not be further described here.

[0077] Please refer to Figure 3 and Figure 4, as a preferred embodiment, the workpiece carrying module 1 comprises a mounting base 11 and a positioning structure, the positioning structure comprises a mounting core barrel 12, a rotating sleeve 13 and an elastic member 14, the mounting core barrel 12 is provided with a positioning groove 121 for positioning the first workpiece 71; the rotating sleeve 13 is fixedly sleeved on the outside of the mounting core barrel 12 and the rotating sleeve 13 and the mounting base 11 are rotationally connected; the elastic member 14 is sleeved on the outside of the mounting core barrel 12 and cooperates with the rotating sleeve 13; wherein the mounting core barrel 12 and the rotating sleeve 13 can move relatively in the axial direction and have a preset lower locking position, when the first workpiece 71 is placed into the positioning groove 121, the elastic member 14 is compressed to drive the mounting core barrel 12 and the rotating sleeve 13 to move to the lower locking position and remain fixed. In this embodiment, the elastic member 14 is a spring. By providing the workpiece carrying module 1 with the positioning structure, it is ensured that the workpiece remains fixed during the process of rotary glue wiping and does not displace, ensuring the uniformity of glue wiping.

[0078] Preferably, the top of the mounting core barrel 12 is provided with symmetrically distributed clamping jaws 122, which enclose the positioning groove 121. When the first workpiece 71 is placed into the positioning groove 121, the clamping jaws 122 are elastically deformed by the extrusion of the workpiece to tightly fit the outer peripheral surface of the first workpiece 71. In this embodiment, the first workpiece 71 is a moving iron core, and the outer peripheral surface of the moving iron core is a cylindrical surface that adapts to the elastic deformation of the clamping jaws 122. The clamping jaws 122 achieve axial positioning and circumferential anti-rotation of the moving iron core through elastic clamping, ensuring that the moving iron core is stable and does not deflect during glue wiping.

[0079] Please refer to Figures 5 to 10 , as a preferred embodiment, the feeding device 2 comprises a first feeding device 21 and a second feeding device 22, and the glue dispensing device 3 comprises a first glue dispensing device 31 and a second glue dispensing device 32; the first feeding device 21 comprises a first material taking manipulator 211 for placing the first workpiece 71 on the workpiece carrying module 1; the second feeding device 22 comprises a second material taking manipulator 221 for assembling the second workpiece 72 to the first workpiece 71 to form a workpiece assembly 7; the first glue dispensing device 31 is used for coating glue on the first workpiece 71; the second glue dispensing device 32 is used for coating glue on the workpiece assembly 7, comprising a glue dispensing pen 322 and a second workpiece self-rotation driving module 321, the glue dispensing pen 322 is used for coating glue on the workpiece assembly 7, and the second workpiece self-rotation driving module 321 is used for driving the workpiece carrying module 1 to self-rotate; wherein the first feeding device 21, the first glue dispensing device 31, the second feeding device 22 and the second glue dispensing device 32 are sequentially arranged on the outer peripheral side of the rotary machine 10 along the rotation direction of the rotary machine 10.

[0080] Specifically, the first feeding device 21 comprises a first material taking manipulator 211 and a first feeding assembly 213. The first feeding assembly 213 is driven by a cylinder to send a feeding tray containing the first workpiece 71 to a material taking position below the first material taking manipulator 211. The first material taking manipulator 211 is driven by a cylinder to approach the first workpiece 71 for taking material, and is driven by a cylinder to move along a horizontal guide rail to the workpiece carrying module 1 for feeding the first workpiece 71. It should be noted that the structure and driving mode of the first material taking manipulator 211 and the first feeding assembly 213 adopt a conventional design in the art, which will not be further described here.

[0081] The first feeding device 21 further comprises a first jacking assembly 212 arranged directly below the workpiece carrying module 1, which comprises a jacking block 2121 and a linear driving member 2122. The linear driving member 2122 is used to drive the jacking block 2121 to move longitudinally and make the jacking block 2121 contact the lower surface of the rotating sleeve 13. When the workpiece carrying module 1 is in an initial locking state, the elastic member 14 is in a compressed state, so that the mounting core barrel 12 and the rotating sleeve 13 are kept at a preset lower locking position relative to the mounting base 11.

[0082] When the first feeding device 21 feeds, the linear driving member 2122 drives the jacking block 2121 to move upward and push the lower surface of the rotating sleeve 13 against the compression elastic force of the elastic member 14, so as to drive the mounting core barrel 12 and the rotating sleeve 13 to move upward synchronously, and further lift the positioning groove 121. At this time, the compression amount of the elastic member 14 is reduced or partially released, so that the workpiece carrying module 1 is in a relaxed state for feeding.

[0083] The first material taking manipulator 211 places the first workpiece 71 in the positioning groove 121 which is lifted to a high position and is in a relaxed state for feeding.

[0084] When the first workpiece 71 is placed in position, the linear driving member 2122 drives the jacking block 2121 to move downward. After losing support, the mounting core barrel 12 and the rotating sleeve 13 move downward synchronously under the reset elastic force of the elastic member 14 and the gravity of the first workpiece 71, re-compress the elastic member 14, and return to the initial lower locking position, so that the workpiece carrying module 1 recovers to a locking state, firmly positions and carries the first workpiece 71. The linear driving member 2122 includes but is not limited to a cylinder, a linear push rod and a motor.

[0085] Specifically, the first dispensing device 31 comprises a glue storage syringe (not shown in the figure), a first dispensing driving member 311 and a dispensing execution member 312. The first dispensing driving member 311 drives the first dispensing device 31 to move horizontally close to the workpiece carrying module 1, and drives the dispensing execution member 312 to dispense glue to the first workpiece 71. It should be noted that the structure and driving mode of the first dispensing driving member 311 and the dispensing execution member 312 adopt the conventional design in the art, which will not be further elaborated here.

[0086] Specifically, the second dispensing device 32 comprises a dispensing pen 322 and a second dispensing driving member 323. The second dispensing driving member 323 drives the dispensing pen 322 to dispense glue close to the workpiece assembly 7. During the dispensing process of the dispensing pen 322, the second workpiece self-rotation driving module 321 drives the workpiece carrying module 1 to self-rotate, so that the dispensing pen 322 forms a continuous glue line along the joint of the first workpiece 71 and the second workpiece 72 in the self-rotation process of the workpiece assembly 7. It should be noted that the structure and driving mode of the dispensing pen 322 and the second dispensing driving member 323 adopt the conventional design in the art, which will not be further elaborated here.

[0087] The first workpiece 71 is pre-dispensed by the first dispensing device 31, which ensures that the second workpiece 72 is preliminarily bonded when assembled with the first workpiece 71. Then, the second dispensing device 32 rotates and dispenses glue at the assembly joint of the workpiece assembly 7 to form a complete and continuous glue line, so that the glue is uniformly distributed at the joint axis, ensuring the connection firmness of the workpiece assembly 7.

[0088] As a preferred embodiment, the second feeding device 22 further comprises a vibrating feeding assembly 222 and a rotating transfer table 223. The vibrating feeding assembly 222 is independently arranged outside the rotating direction of the rotating machine table 10, and is used to feed the second workpiece 72 to the rotating transfer table 223. The rotating transfer table 223 comprises a docking position 2231, a material taking position 2232 and a rotating driving member 2233. The docking position 2231 is used to receive the second workpiece 72 fed by the vibrating feeding assembly 222, and the material taking position 2232 is used to carry the second workpiece 72 to be taken by the second material taking robot 221. The rotating transfer table 223 alternately switches the docking position 2231 and the material taking position 2232 through the rotating driving member 2233 to respectively align with the vibrating feeding assembly 222 and the workpiece carrying module 1.

[0089] Specifically, the vibration feeding assembly 222 includes a vibration feeding tray 2221 and a feeding guide rail 2222. The vibration feeding tray 2221 sorts the second workpieces 72 in orientation by vibration and conveys the second workpieces 72 to the outlet end of the feeding guide rail 2222. The outlet end of the feeding guide rail 2222 is connected to the docking position 2231 of the rotating transfer platform 223, and the second workpieces 72 are fed into the docking position 2231 by air flow assistance. The air flow assistance includes, but is not limited to, air pipe blowing, etc. It should be noted that the structure and working principle of the vibration feeding assembly 222 are prior art, and will not be further described here.

[0090] In the embodiment, the docking position 2231 and the material taking position 2232 are symmetrically arranged, and the rotating drive member 2233 is rotated by 180° to realize the alternating switching. It can be understood that the work position configuration of the rotating transfer platform 223 is not limited to the 180° double work position configuration of the embodiment. According to the production rhythm requirement, a three work position (120° uniform distribution) or a four work position (90° uniform distribution) configuration can also be selected, and the work position switching can be realized by adjusting the rotation angle of the rotating drive member 2233. These deformation modes all fall within the protection scope of the present application.

[0091] When the second feeding device 22 feeds, the second material taking manipulator 221 takes away the second workpiece 72 from the material taking position 2232 under the driving of the air cylinder, and moves to the workpiece carrying module 1 to place the second workpiece 72 on the first workpiece 71 which has been positioned on the workpiece carrying module 1, thereby forming the workpiece assembly 7. In the embodiment, the first workpiece 71 is a moving iron core, and the second workpiece 72 is a tripping device push rod. The moving iron core has a guide groove, so that the tripping device push rod can be quickly aligned and assembled.

[0092] The rotating transfer platform 223 is designed by rotating switching of the docking position 2231 and the material taking position 2232. While the vibration feeding assembly 222 continuously feeds, it ensures that the material taking position 2232 always has the second workpiece 72, so that the second material taking manipulator 221 can take the material without waiting. The compact layout of the rotating switching avoids the space waste of the linear feeding of the traditional dispensing machine, and also realizes uninterrupted feeding, thereby ensuring the production continuity.

[0093] Please refer to Figures 12 to 16, as a preferred embodiment, the rubber wiping module 51 comprises: a horizontal adjustment assembly 512, including a movable mounting base 5121, two guide wheels 5122 and a first driving member 5123; the two guide wheels 5122 are symmetrically arranged on both sides of the workpiece carrying module 1 and are fixed to the mounting base 5121 to provide a linear wiping member 511 passing channel; the first driving member 5123 is connected with the mounting base 5121 for driving the mounting base 5121 to move horizontally to drive the two guide wheels 5122 to move horizontally, so as to adjust the contact state between the linear wiping member 511 between the two guide wheels 5122 and the workpiece assembly 7; a vertical adjustment assembly 513, including a second driving member 5131, the second driving member 5131 is fixed to a moving seat 5132, the output end is connected with a pressing member 5133, the pressing member 5133 is arranged between the two guide wheels 5122 and on one side of the workpiece carrying module 1, for pressing the linear wiping member 511 to closely contact the wiping surface of the workpiece assembly 7, the second driving member 5131 is used for driving the pressing member 5133 to move longitudinally relative to the wiping surface of the workpiece assembly 7. The first driving member 5123 and the second driving member 5131 include but are not limited to air cylinder, electric push rod and motor.

[0094] By arranging the horizontal adjustment assembly 512, the first driving member 5123 can drive the mounting base 5121 to move along the transverse direction close to or away from the workpiece assembly 7, and then drive the two guide wheels 5122 to move along the transverse direction close to or away from the workpiece assembly 7, so as to flexibly adjust the contact state between the linear wiping member 511 and the workpiece assembly 7 to adapt to the precision requirements of different curved surfaces of the workpiece assembly 7; at the same time, the two guide wheels 5122 are symmetrically arranged to form a stable wiping member passing channel, which can avoid damage or uneven wiping of the linear wiping member 511 due to force deviation, and ensure that the linear wiping member 511 and the workpiece assembly 7 maintain uniform contact to improve the wiping effect.

[0095] The vertical adjusting assembly 513 is used to move the pressing member 5133 relative to the wiping surface of the workpiece assembly 7; since the pressing member 5133 is used to press the linear wiping member 511 and can adjust the pressing force under the control of the second driving member 5131, the linear wiping member 511 can simulate the up-and-down wiping of the surface of the workpiece assembly 7 by a human hand, greatly improving the flexibility of the glue wiping. In the embodiment, the workpiece assembly 7 is an assembly formed by a moving iron core and a trip lever, the moving iron core has a guide slot forming a gap, and the mating surface of the trip lever and the moving iron core is an arc-shaped curved surface. For the gap or complex curved surface on the workpiece assembly 7, the linear wiping member 511 can actively adapt to the surface form of the workpiece assembly 7, better fit these surfaces, wipe the multiple surfaces of the workpiece assembly 7 at a suitable angle and pressure, and also can go deep into the gap area, more accurately wipe off the glue on these surfaces, and significantly improve the glue wiping effect on the workpiece assembly 7 with complex form.

[0096] As a preferred embodiment, the pressing member 5133 has a U-shaped or C-shaped opening facing the wiping surface of the workpiece assembly 7, and the U-shaped or C-shaped opening has two pressure arms 51331, and the ends of the two pressure arms 51331 press the linear wiping member 511 respectively. In this way, the pressure can be more evenly distributed on the linear wiping member 511, ensuring that the linear wiping member 511 can well fit the surface of the workpiece assembly 7 on the surface of the workpiece assembly 7 with different shapes.

[0097] Preferably, the pressing member 5133 has a U-shaped opening facing the wiping surface of the workpiece assembly 7. The symmetric double pressure arms 51331 of the U-shaped structure can realize completely balanced force distribution, avoid the pressure deviation caused by the pressing member 5133 pressing the linear wiping member 511, make the contact pressure of the linear wiping member 511 and the surface of the workpiece assembly 7 more uniform, and further ensure that the glue on the workpiece assembly 7 can be wiped off with equal force, improving the uniformity of the glue wiping.

[0098] As a preferred embodiment, the glue wiping module 51 further comprises a wire roller 514 and a tension adjusting device, and the tension adjusting device is arranged at the starting position of the wiping member moving path, used to pull out the linear wiping member 511 from the wire roller 514 and adjust the tension of the linear wiping member 511. The coordinated arrangement of the wire roller 514 and the tension adjusting device forms a system capable of dynamically adjusting the tension state of the linear wiping member 511, which can adjust the tension in real time according to the actual operation of the linear wiping member 511, ensure that the linear wiping member 511 always maintains a suitable tension, so that the linear wiping member 511 will not deviate due to relaxation, or cause wear or breakage of the linear wiping member 511 due to over-tightening, and further ensure the stability of the glue wiping effect of the linear wiping member 511, and improve the glue wiping quality.

[0099] As a preferred embodiment, the tension adjusting device comprises a tensioner 515. The tensioner 515 can achieve highly precise control of the tension size. During the glue wiping process, the tension value can be adjusted in detail according to the glue wiping requirements of different workpiece assemblies 7 and the type of the linear wiping member 511.

[0100] As a preferred embodiment, the glue wiping module 51 further comprises an auxiliary guiding assembly 516, which is installed between the tensioner 515 and the residual glue recycling module 53. The auxiliary guiding assembly 516 comprises a guiding groove 5162 and a plurality of guiding rollers 5161, which are in rolling contact with the linear wiping member 511. The guiding groove 5162 contains cleaning solvent.

[0101] The auxiliary guiding assembly 516 forces the linear wiping member 511 to move along the preset path by arranging a plurality of guiding rollers 5161, so as to avoid the deviation of the travel path of the linear wiping member 511 caused by tension changes or external interference. At the same time, the rolling contact between the guiding rollers 5161 and the linear wiping member 511 can reduce the wear of the linear wiping member 511. In addition, the cleaning solvent contained in the guiding groove 5162 can make the linear wiping member 511 soak in the cleaning solvent during the travel process, thereby improving the cleaning effect on the uncured residual glue. The cleaning solvent includes but is not limited to alcohol.

[0102] As a preferred embodiment, the first workpiece self-rotation driving module 52 comprises a base 521, a fourth driving member 522 and a fifth driving member 523. The fourth driving member 522 is fixed on the base 521, and the output end of the fourth driving member 522 is connected with a moving part 5221. The fifth driving member 523 is fixed on the moving part 5221. The fourth driving member 522 is used to drive the fifth driving member 523 to move close to or away from the lower end of the workpiece carrying module 1 in the horizontal direction. The output end of the fifth driving member 523 is connected with a main rotating sleeve connecting member 5231. The slave rotating sleeve connecting member 15 is sleeved outside the rotating sleeve 13 of the workpiece carrying module 1 and is fixed in the circumferential direction. When the fifth driving member 523 moves to the lower end of the workpiece carrying module 1, the fifth driving member 523 drives the main rotating sleeve connecting member 5231 to rotate and contact with the slave rotating sleeve connecting member 15, so as to drive the workpiece carrying module 1 to self-rotate. The fourth driving member 522 includes but is not limited to a pneumatic cylinder, an electric push rod and a motor. The fifth driving member 523 includes but is not limited to a rotating motor.

[0103] It should be noted that the second workpiece self-rotation driving module 321 of the second dispensing device 32 described above adopts the same structure as the first workpiece self-rotation driving module 52 of the present embodiment.

[0104] Since the fifth driving member 523 can move horizontally under the driving of the fourth driving member 522, the contact position and contact pressure between the main rotary sleeve connecting member 5231 and the slave rotary sleeve connecting member 15 can be adjusted for different positions of the workpiece carrying module 1, thereby adapting to workpiece assemblies 7 of different specifications and sizes, and improving the versatility of the workpiece rotation driving module.

[0105] As a preferred embodiment, the residual glue recycling module 53 comprises a pressing assembly 531 and a recycling assembly 532. The pressing assembly 531 comprises a third driving member 5311 and a pressing member 5312, and the third driving member 5312 is used to drive the pressing member 5311 to press the residual glue on the linear wiping member 511. The recycling assembly 532 is independently arranged below the pressing assembly 531 and is used to recycle the residual glue and the linear wiping member 511. The recycling assembly 532 comprises but is not limited to a recycling groove or a collection cavity. The third driving member 5311 comprises but is not limited to a rotary motor.

[0106] By arranging the residual glue recycling module 53 comprising the pressing assembly 531 and the recycling assembly 532, the pressing assembly 531 can be used before the linear wiping member 511 with residual glue falls into the recycling assembly 532. Specifically, the third driving member 5311 drives the pressing member 5312 to press the linear wiping member 511, so that the residual glue is separated from the linear wiping member 511. In this way, the residual glue falling into the recycling assembly 532 is more pure and regular in shape, and is easier to filter and reuse subsequently.

[0107] Preferably, the third driving member 5311 is a rotary motor, the output end of the third driving member 5311 is connected with a driving gear 53111, one side of the driving gear 53111 is engaged with a driven gear 53112, and the driving gear 53111 and the driven gear 53112 are respectively connected with a pressing member 5312 through a rotating shaft. When the third driving member 5311 drives the driving gear 53111 to rotate, according to the gear engagement principle, the driven gear 53112 will rotate in the opposite direction of the driving gear 53111, thereby driving the pressing members 5312 to rotate relatively; the pressing members 5312 move close to each other, thereby pressing the linear wiping member 511 with residual glue, so that the residual glue is separated from the linear wiping member 511 and falls into the recycling assembly 532. The pressing members 5312 comprise but are not limited to rollers, compression rollers and bushings.

[0108] Further preferably, the number of teeth of the driving gear 53111 and the driven gear 53112 are different. The difference in the number of teeth of the gears enables the two pressing members 5312 to generate a speed difference when rotating in opposite directions. When the two pressing members 5312 rotate in opposite directions at different speeds and press the linear wiping member 511, the speed difference generates a friction force difference on the contact surface between the pressing members 5312 and the linear wiping member 511. The unbalanced friction force generates a traction effect, continuously pulling the linear wiping member 511 to move along the preset path and eventually falling into the recycling assembly 532.

[0109] Further preferably, in other embodiments, the number of teeth of the driving gear 53111 and the driven gear 53112 are the same, and the two pressing members 5312 are made of different surface materials or are provided with different surface patterns to form a friction force difference. For example, one pressing member 5312 is made of rubber material with high friction coefficient or is provided with diagonal lines, and the other pressing member 5312 is made of metal material with low friction coefficient or is provided with straight lines. The surface characteristics of the pressing members 5312 also enable the two pressing members 5312 to generate a traction effect during reverse rotation, driving the linear wiping member 511 to move and feed.

[0110] Preferably, the pressing assembly 531 further comprises a fixing assembly 5313 for fixing the linear wiping member 511, and the fixing assembly 5313 is arranged directly above the two pressing members 5312. During the pressing process, the linear wiping member 511 is easily displaced by the force of the pressing members 5312, affecting the pressing effect. By arranging the fixing assembly 5313, the displacement of the linear wiping member 511 during the pressing of the residual glue by the pressing members 5312 can be prevented, ensuring the stability of the linear wiping member 511 during the pressing process, and thus fully pressing the residual glue on the linear wiping member 511. The fixing assembly 5313 includes but is not limited to a bushing or a hollow rod.

[0111] As a preferred embodiment, the linear wiping member 511 is a multi-strand fiber line. The multi-strand fiber line as the linear wiping member 511 can freely increase or decrease the number of fiber strands in the linear wiping member 511 to meet the wiping needs of workpiece assemblies 7 of different sizes. The loose structure of the multi-strand fiber line enables it to penetrate into the fine gaps of the workpiece assembly 7 during wiping, effectively adsorbing and removing the residual glue, and achieving thorough cleaning of the workpiece assembly 7. The fiber line includes but is not limited to cotton thread, linen thread, nylon thread, and polyester thread.

[0112] In this embodiment, the number of strands of the multi-strand fiber line is 6; in other embodiments, the number of strands of the multi-strand fiber line can be 3, 4, 5, 8, or 10, which is not limited here.

[0113] Preferably, the multi-strand fiber line is a multi-strand cotton line. Cotton line has good flexibility and fluffiness, can better fit the surface of workpiece assembly 7 of different sizes, and is especially suitable for complex structures with concave-convex or curved surfaces. In the embodiment, the workpiece assembly 7 is formed by the moving iron core and the trip lever assembly, and the multi-strand cotton line can better fit the arc surface formed by the trip lever of the workpiece assembly 7 and the edge gap of the guide groove of the moving iron core. The cotton line designed with a standard bundle can ensure the fit and wiping effect when the number of cotton lines is increased or decreased to meet the wiping needs of the workpiece assembly 7. At the same time, the multi-strand cotton line is convenient to operate, and the residual glue attached to the surface of the cotton line can be collected through the residual glue collection module 53, which significantly improves the recovery rate of residual glue. The multi-strand cotton line also has strong toughness and is not easy to break during wiping. In addition, cotton line is widely available and low in cost, which is economically applicable.

[0114] Please refer to Figure 11 , as a preferred embodiment, further comprising a glue monitoring device arranged on one side of the workpiece carrying module 1 and facing the workpiece assembly 7, for monitoring the dispensing and / or wiping state of the workpiece assembly 7, comprising: an industrial camera 8, the lens field of view of the industrial camera 8 covers the workpiece assembly 7; an excitation light source configured to be aligned with the workpiece assembly 7. The excitation light source includes but is not limited to an ultraviolet light source.

[0115] By arranging the glue monitoring device, the glue distribution state of the workpiece assembly 7 can be monitored in real time. On the one hand, the glue monitoring device can confirm the continuity and coverage of the glue line after dispensing glue on the workpiece assembly 7; on the other hand, the glue monitoring device monitors residual glue marks, effectively controls the cleaning scale, avoids unnecessary damage to the workpiece assembly 7 caused by excessive cleaning, and prevents insufficient cleaning from causing residual glue to remain on the workpiece assembly 7.

[0116] In the embodiment, the excitation light source is an ultraviolet light source 41. Specifically, the glue used in the operation contains fluorescent substances, which can produce characteristic fluorescence under the irradiation of ultraviolet light. The fluorescence signal can be captured by the industrial camera 8; in this way, the industrial camera 8 cooperates with the ultraviolet light source 41 to obtain the fluorescence image of the surface of the workpiece assembly 7. When there is no fluorescence on the surface of the workpiece assembly 7, i.e. when the continuous multiple images taken by the industrial camera 8 show that there is no residual glue on the workpiece assembly 7, it is determined that there is no residual glue on the workpiece assembly 7.

[0117] In the present embodiment, the industrial camera 8 and the ultraviolet light source 41 are fixedly arranged on a bracket 81, which is installed on the adjacent station (i.e. the station where the curing device 4 is located) between the second dispensing device 32 and the wiping module 51, and the bracket 81 drives the industrial camera 8 to rotate through a rotating mechanism (not shown in the figure). Through the rotation of the bracket 81, the field of view of the lens of the industrial camera 8 and the irradiation range of the ultraviolet light source 41 can be synchronously switched to point to the workpiece carrying module 1 of the second dispensing device 32 and the wiping and residual glue recycling device 5. When the bracket 81 is rotated to face the workpiece carrying module 1 of the second dispensing device 32, the industrial camera 8 and the ultraviolet light source 41 are used to monitor the dispensing state of the workpiece assembly 7; when the bracket 81 is rotated to face the workpiece carrying module 1 of the wiping module 51, the industrial camera 8 and the ultraviolet light source 41 are used to monitor the wiping state of the workpiece assembly 7. At the same time, the ultraviolet light source 41 also serves as the curing light source of the curing device 4. When the workpiece assembly 7 is conveyed to the curing station by the rotating machine 10, the bracket 81 can be rotated to the corresponding position to make the ultraviolet light source 41 align with the dispensing area of the workpiece assembly 7, and the glue is cured by ultraviolet light.

[0118] By multiplexing the ultraviolet light source 41 as the curing light source of the curing device and the excitation light source of the glue monitoring device, and synchronously switching the industrial camera 8 and the ultraviolet light source 41 to different stations through the bracket 81, not only the structure of the dispensing machine is simplified, but also the glue monitoring device can cover multiple monitoring scenarios such as after dispensing and after wiping, thereby improving the versatility and functionality of the glue monitoring device.

[0119] In other embodiments, the bracket 81 on which the industrial camera 8 is installed is fixedly arranged, and the industrial camera 8 is configured with a wide-angle lens to cover the workpiece carrying module 1 of the second dispensing device 32 and the wiping module 51 at the same time; or multiple industrial cameras 8 can be arranged, and the industrial cameras 8 arranged at the second dispensing device 32 and the wiping module 51 are specially used to monitor the second dispensing device 32 and the wiping module 51.

[0120] Please refer to Figure 17 As a preferred embodiment, the material collecting device 6 includes a material collecting manipulator 61, a second lifting assembly 62 and a material collecting conveying assembly 63. The material collecting conveying assembly 63 includes a material collecting disc 631 and a conveying belt 632, which are used to receive the workpiece assembly 7 collected by the material collecting manipulator 61. It should be noted that the structure and driving mode of the material collecting conveying assembly 63 adopt the conventional design in the art, which will not be further described here.

[0121] When the material receiving device 6 receives materials, the second lifting assembly 62 moves upward to push the rotating sleeve 13, overcomes the compressive elastic force of the elastic member 14, and drives the mounting core barrel 12 and the rotating sleeve 13 to move upward synchronously, so that the compression amount of the elastic member 14 is reduced or partially released, and the locking state of the workpiece carrying module 1 is released, so that the workpiece carrying module 1 is in a relaxed state waiting for material to be taken.

[0122] The receiving robot 61 is driven by a cylinder to approach the workpiece carrying module 1 and receive the workpiece assembly 7 .

[0123] After collecting the workpiece, the second lifting assembly 62 moves downward. Under the action of the restoring elastic force of the elastic member 14, the mounting core barrel 12 and the rotating sleeve 13 move downward synchronously, re-compress the elastic member 14, and return to the preset lower locking position, so that the workpiece carrying module 1 returns to the initial locking state.

[0124] It should be noted that the second lifting assembly 62 of this embodiment has the same structure and the same working principle as the aforementioned first lifting assembly 212 .

[0125] Preferably, the dispensing machine also includes a control system, which usually uses a PLC (programmable logic controller) or a PC (personal computer) as a control unit, and is connected to the drive components, industrial camera 68 and ultraviolet light source 41 of each device through wired or wireless communication, and controls the automatic operation of each device through the control system.

[0126] The glue dispensing machine of the present invention is suitable for workpieces requiring glue dispensing, and is particularly suitable for workpieces with complex curved surfaces, such as workpieces with threads or slits on their surfaces. By adopting a linear wiper 511, the linear wiper 511 can fit tightly with the slit or complex curved surface of the workpiece. At the same time, the first workpiece self-rotation drive module 52 drives the workpiece to rotate, so that the linear wiper 511 and the workpiece achieve multi-dimensional surface contact, thereby achieving continuous wiping of the workpiece without blind spots, significantly improving the glue wiping effect of the workpiece. By providing a residual glue recovery module 53 for recovering residual glue and the linear wiper 511, the wiping surface of the linear wiper 511 can be updated in real time, significantly reducing the frequency of wiper replacement. Since the linear wiper 511 falls into the residual glue recovery module 53 after glue wiping, there is no need to stop the linear wiper 511 for refueling even if it is saturated, thereby improving production efficiency. In addition, by providing the residual glue recovery module 53, the residual glue after glue wiping can also be recovered, and the recovered glue can be reused after filtering, reducing the waste of consumables.

As such, it is submitted that the foregoing description and examples have been apparent in terms of their structures and functions, and are susceptible to various changes without departing from the spirit or essence thereof.
