Description

Technical Field

[0001] This utility model relates to the field of dispensing machine technology, and more specifically, to an automatic glue-wiping and residual glue recycling device. Background Technology

[0002] To ensure secure bonding between workpieces, adhesive materials are unavoidable. Dispensing refers to the process of precisely applying fluid adhesive materials, either manually or with specialized equipment, to designated locations on a target workpiece in different forms such as "dots," "lines," or "surfaces." Dispensing is required in various industrial production and manufacturing scenarios: for example, in the electronics industry, adhesive is used to seal connector interfaces, improving connection reliability; in the automotive manufacturing industry, adhesive is used to protect internal electronic components from harsh environments such as vibrations or high temperatures during vehicle operation; in medical equipment, adhesive is used to seal medical devices such as syringes and infusion sets, ensuring their sterility and safety. Moving iron cores, sensor chips, and solenoid valve cores are common workpieces requiring dispensing. Traditional dispensing processes often involve manual application and wiping away excess adhesive, resulting in difficulties in controlling the amount dispensed and inconsistent cleanliness after wiping. Furthermore, existing dispensing technologies still have some shortcomings:

[0003] Firstly, the adhesive application effect is unstable. Existing cloth wiping devices cannot closely adhere to complex workpiece surfaces, such as narrow slits or complex curved surfaces, resulting in discontinuous contact between the wiping device and the workpiece surface, creating wiping blind spots and affecting the stability of the adhesive application effect.

[0004] Secondly, the maintenance costs are high. The existing cloth wiping parts are prone to adhesive saturation and need to be replaced frequently, which reduces production efficiency due to downtime for material changes. Utility Model Content

[0005] The purpose of this invention is to provide an automatic adhesive wiping and residual adhesive recycling device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0007] This utility model provides an automatic adhesive wiping and residual adhesive recycling device, including: an adhesive wiping module, a workpiece bearing module, a workpiece self-rotation drive module, and a residual adhesive recycling module.

[0008] The adhesive wiping module includes a linear wiping component, which moves along a preset path and wipes the workpiece at a designated position within the preset path;

[0009] The workpiece carrying module is used to carry the workpiece;

[0010] The workpiece rotation drive module is used to drive the workpiece on the workpiece carrying module to rotate.

[0011] The residual adhesive recovery module is located at the end of the wiping component's movement path and is used to recover residual adhesive and the linear wiping component.

[0012] In some embodiments of this application, the adhesive wiping module includes a movable mounting base, two guide wheels, and a first driving member; the two guide wheels are symmetrically arranged on both sides of the workpiece carrying module and fixed to the mounting base, providing a channel for the linear wiping member to pass through; the first driving member is connected to the mounting base and is used to drive the mounting base to move horizontally so as to drive the two guide wheels to move horizontally, thereby adjusting the contact state between the linear wiping member and the workpiece between the two guide wheels.

[0013] In some embodiments of this application, the adhesive wiping module further includes a second driving member, which is fixed to the movable base and has an output end connected to a clamping member. The clamping member is located between two guide wheels and disposed on one side of the workpiece bearing module, and is used to clamp the linear wiping member to make close contact with the wiping surface of the workpiece. The second driving member is used to drive the clamping member to move longitudinally relative to the wiping surface of the workpiece.

[0014] In some embodiments of this application, the clamping member has a U-shaped or C-shaped opening facing the wiping surface of the workpiece, and the U-shaped or C-shaped opening has two pressure arms, the ends of which respectively press against the linear wiping member.

[0015] In some embodiments of this application, the adhesive wiping module further includes a linear roller and a tension adjusting device. The tension adjusting device is located at the starting position of the wiping component's movement path and is used to pull out the linear wiping component from the linear roller and adjust the tension of the linear wiping component. The tension adjusting device includes a tensioning machine.

[0016] In some embodiments of this application, the adhesive wiping module further includes an auxiliary guiding device, which is installed between the tension adjusting device and the residual adhesive recovery module and includes several guide rollers that make rolling contact with the linear wiping component.

[0017] In some embodiments of this application, the residual adhesive recovery module includes an extrusion device and a recovery device. The extrusion device includes a third driving member and an extruder. The third driving member is used to drive the extruder to extrude the residual adhesive on the linear wiping member. The recovery device is independently disposed below the extrusion device and is used to recover the residual adhesive and the linear wiping member.

[0018] In some embodiments of this application, the linear wiping element is a multi-strand fiber thread.

[0019] Some embodiments of this application also include a residual adhesive monitoring device, which is disposed on one side of the workpiece carrying module and faces the workpiece, for monitoring whether there is residual adhesive on the workpiece.

[0020] In some embodiments of this application, the residual adhesive monitoring device includes an industrial camera and an ultraviolet light source, wherein the lens of the industrial camera covers the workpiece, and the ultraviolet light source is configured to be aimed at the workpiece.

[0021] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

[0022] 1. Excellent adhesive removal effect. The automatic adhesive removal and residual adhesive recovery equipment of this utility model adopts a linear wiping component. The linear wiping component can closely fit the narrow slit or the complex curved surface of the workpiece. At the same time, the workpiece is driven to rotate by the workpiece rotation drive module, so that the linear wiping component and the workpiece can achieve multi-dimensional surface contact, thereby realizing continuous wiping of the workpiece without blind spots and significantly improving the adhesive removal effect of the workpiece.

[0023] 2. Low maintenance cost. This utility model's automatic adhesive wiping and residual adhesive recovery equipment provides raw materials for linear wiping parts via a linear roller, maintains tension on the linear wiping parts using a tension adjustment device, and guides the movement path of the linear wiping parts by guide rollers and guide wheels. Finally, the residual adhesive and linear wiping parts are recovered in the residual adhesive recovery module. The coordinated operation of all components achieves continuous feeding of the linear wiping parts, enabling real-time updates to the wiping surface of the linear wiping parts, significantly reducing the frequency of wiping part replacement. Furthermore, since the linear wiping parts fall into the recovery device along with the residual adhesive after wiping, there is no need to stop the machine to change materials even when the linear wiping parts are saturated, thus improving production efficiency.

[0024] 3. Resource Reuse. The automatic glue-wiping and residual glue recycling equipment of this utility model, by setting up a residual glue recycling module, enables the recycling of residual glue after glue wiping. The recycled glue can be reused after filtration, reducing the waste of consumables. Attached Figure Description

[0041] Although the present invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0042] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0043] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0044] Please see Figures 1 to 7 The automatic glue-wiping and residual glue recycling equipment provided in one embodiment of this utility model mainly includes a glue-wiping module 1, a workpiece bearing module 2, a workpiece self-rotation drive module 3, and a residual glue recycling module 4.

[0045] The adhesive wiping module 1 includes a linear wiping component 11, which moves along a preset path and wipes the workpiece 5 at a designated position within the preset path;

[0046] The workpiece carrying module 2 is used to carry the workpiece 5;

[0047] The workpiece rotation drive module 3 is used to drive the workpiece 5 on the workpiece bearing module 2 to rotate.

[0048] The residual adhesive recovery module 4 is located at the end of the wiping component's movement path and is used to recover residual adhesive and the linear wiping component 11.

[0049] The automatic adhesive wiping and residual adhesive recovery equipment of this utility model adopts a linear wiping component 11. The linear wiping component 11 can closely fit the slit or the complex curved surface of the workpiece 5. At the same time, the workpiece 5 is rotated by the workpiece rotation drive module 3, so that the linear wiping component 11 and the workpiece 5 can achieve multi-dimensional surface contact, thereby realizing continuous wiping of the workpiece 5 without blind spots and significantly improving the adhesive wiping effect of the workpiece 5. The automatic adhesive wiping and residual adhesive recovery equipment of this utility model, by setting up a residual adhesive recovery module 4 for recovering residual adhesive and linear wiping component 11, can update the wiping surface of the linear wiping component 11 in real time, significantly reducing the frequency of wiping component replacement. Since the linear wiping component 11 falls into the recovery device 42 along with the residual adhesive after wiping, there is no need to stop the machine to change materials even when the linear wiping component 11 is saturated, which improves production efficiency. At the same time, the setting of the residual adhesive recovery module 4 allows the residual adhesive after wiping to be recovered. The recovered adhesive can be reused after filtration, reducing the waste of consumables.

[0050] In a preferred embodiment, the adhesive wiping module 1 includes a movable mounting base 12, two guide wheels 121, and a first driving member 122. The two guide wheels 121 are symmetrically arranged on both sides of the workpiece carrying module 2 and fixed to the mounting base 12, providing a passage for the linear wiping member 11. The first driving member 122 is connected to the mounting base 12 and is used to drive the mounting base 12 to move horizontally, thereby moving the two guide wheels 121 horizontally and adjusting the contact state between the linear wiping member 11 and the workpiece 5. The first driving member 122 can be a cylinder, an electric push rod, a servo motor, or a linear motor, etc.

[0051] By setting a movable mounting base 12, two guide wheels 121 symmetrically fixed to the mounting base 12 and forming a wiping component passage channel, and a first driving member 122 that drives the mounting base 12 to move, the first driving member 122 can drive the mounting base 12 to move in a lateral direction closer to or farther from the workpiece 5, thereby driving the two guide wheels 121 to move in a lateral direction closer to or farther from the workpiece 5. The contact state between the linear wiping component 11 and the workpiece 5 can be flexibly adjusted to adapt to the precision requirements of different curved surfaces of the workpiece 5. At the same time, the symmetrical arrangement of the two guide wheels 121 forms a stable wiping component passage channel, which can avoid damage to the linear wiping component 11 or uneven glue application due to force deviation, ensuring uniform contact between the linear wiping component 11 and the workpiece 5 and improving the glue application effect.

[0052] Preferably, the first driving component 122 is a cylinder. The cylinder can provide linear reciprocating motion and has the advantages of simple structure, low cost, and easy installation and maintenance; during the process of adjusting the guide wheel 121 to move closer to or further away from the workpiece 5, the cylinder, as the first driving component 122, can quickly realize the movement of the mounting seat 12, thereby improving the glue application efficiency.

[0053] In a preferred embodiment, the mounting base 12 has a U-shaped or C-shaped opening facing the wiping surface of the workpiece 5. By designing the side of the mounting base 12 facing the wiping surface of the workpiece 5 as a U-shaped or C-shaped opening, a relatively stable guide channel can be formed during the adhesive application process, ensuring that the linear wiping element 11 maintains uniform contact pressure with the surface of the workpiece 5, and the U-shaped or C-shaped opening facilitates observation and maintenance of the adhesive application process.

[0054] Preferably, the mounting base 12 has a U-shaped opening. The U-shaped opening of the mounting base 12 has a better symmetrical support structure, which can enhance the stability of the guide wheel 121 during the adhesive application process.

[0055] In a preferred embodiment, the adhesive wiping module 1 further includes a second driving member 1231, which is fixed to the movable seat 123 and has an output end connected to a clamping member 1232. The clamping member 1232 is located between two guide wheels 121 and is disposed on one side of the workpiece bearing module 2. It is used to clamp the linear wiping member 11 to make close contact with the wiping surface of the workpiece 5. The second driving member 1231 is used to drive the clamping member 1232 to move longitudinally relative to the wiping surface of the workpiece 5.

[0056] By setting a movable base 123, a second driving member 1231 fixed to the movable base 123, and a clamping member 1232 connected to the output end of the second driving member 1231, the clamping member 1232 can move longitudinally relative to the wiping surface of the workpiece 5. Since the clamping member 1232 is used to clamp the linear wiping member 11 and can adjust the clamping force under the control of the second driving member 1231, the linear wiping member 11 can simulate the up and down wiping of the surface of the workpiece 5 by a human hand, which greatly improves the flexibility of adhesive wiping. For slits or complex curved surfaces on the workpiece 5, the linear wiping member 11 can actively adapt to the surface shape of the workpiece 5, better fit these surfaces, wipe multiple surfaces of the workpiece 5 with appropriate angle and pressure, and can also penetrate into the slit area to more accurately wipe the glue on these surfaces, which significantly improves the adhesive wiping effect on workpieces with complex shapes.

[0057] In a preferred embodiment, the clamping member 1232 is provided with a limiting device (not shown in the figure) to prevent excessive displacement of the linear wiping member 11. Since the linear wiping member 11 undergoes complex motion when the first driving member 122 drives the mounting base 12 to move laterally and the second driving member 1231 drives the clamping member 1232 to move longitudinally, the limiting device on the clamping member 1232 effectively prevents excessive displacement of the linear wiping member 11 during longitudinal displacement, ensuring that the linear wiping member 11 accurately adheres to the surface of the workpiece 5 for adhesive application, preventing deviation of the linear wiping member 11 during adhesive application, and thus ensuring the stability and quality of adhesive application.

[0058] In a preferred embodiment, the clamping member 1232 has a U-shaped or C-shaped opening facing the wiping surface of the workpiece 5, and the U-shaped or C-shaped opening has two pressure arms 12321, the ends of which respectively press against the linear wiping member 11.

[0059] By setting a clamping member 1232 with a U-shaped or C-shaped opening on the wiping surface facing the workpiece 5, two pressure arms 12321 are formed at one end of the clamping member 1232 facing the wiping surface of the workpiece 5. The ends of the two pressure arms 12321 respectively press the linear wiping member 11, applying pressure to the linear wiping member 11. This allows the pressure to be distributed more evenly on the linear wiping member 11, ensuring that the linear wiping member 11 can fit well with the surface of the workpiece 5 on different shapes.

[0060] Preferably, the clamping member 1232 has a U-shaped opening facing the wiping surface of the workpiece 5. The symmetrical double pressure arms 12321 with the U-shaped structure can achieve a completely balanced force distribution, avoiding pressure deviation that may occur when the clamping member 1232 clamps the linear wiping member 11, making the contact pressure between the linear wiping member 11 and the surface of the workpiece 5 more uniform, thereby ensuring that the adhesive on the workpiece 5 can be wiped off with equal force and improving the uniformity of adhesive wiping.

[0061] In a preferred embodiment, the adhesive wiping module 1 further includes a linear roller 14 and a tension adjusting device 13. The tension adjusting device 13 is located at the starting position of the wiping component's movement path and is used to pull out the linear wiping component 11 from the linear roller 14 and adjust the tension of the linear wiping component 11.

[0062] The coordinated arrangement of the linear roller 14 and the tension adjustment device 13 forms a system that can dynamically adjust the tension of the linear wiping component 11. The tension can be adjusted in real time according to the actual operation of the linear wiping component 11, ensuring that the linear wiping component 11 always maintains a suitable tension. This avoids the linear wiping component 11 becoming too loose or too tight, preventing it from shifting due to looseness or wearing or breaking due to excessive tightness. This ensures the stability of the adhesive application effect of the linear wiping component 11 and improves the adhesive application quality.

[0063] In a preferred embodiment, the tension adjustment device 13 includes a tension machine. The tension machine can achieve highly precise control over the tension, and during the adhesive application process, the tension value can be finely adjusted according to the adhesive application requirements of different workpieces 5 and the type of linear wiping component 11.

[0064] In a preferred embodiment, the adhesive wiping module 1 further includes an auxiliary guiding device 124, which is installed between the tension adjusting device 13 and the residual adhesive recovery module 4 and includes a plurality of guide rollers 1241, which are in rolling contact with the linear wiping member 11.

[0065] The auxiliary guiding device 124 forces the linear wiping member 11 to move along a preset path by setting multiple guide rollers 1241, so as to avoid the deviation of the travel path of the linear wiping member 11 due to tension changes or external interference; at the same time, the rolling contact between the guide rollers 1241 and the linear wiping member 11 can reduce the wear on the linear wiping member 11.

[0066] In a preferred embodiment, the workpiece carrying module 2 is mounted on a rotatable machine base 10. The workpiece carrying module 2 includes a mounting core cylinder 21, a rotating sleeve 22, and a connecting member 23 from the rotating sleeve. The workpiece 5 is mounted on the mounting core cylinder 21. The rotating sleeve 22 is sleeved on the outside of the mounting core cylinder 21 and the two are circumferentially fixed. The connecting member 23 from the rotating sleeve is sleeved on the outside of the rotating sleeve 22 of the workpiece carrying module 2 and the two are circumferentially fixed. The rotation of the machine base 10 can drive the workpiece carrying module 2 to move to the adhesive application module 1, and the workpiece carrying module 2 can rotate under the drive of the workpiece rotation drive module 3.

[0067] The workpiece 5 can be moved to the adhesive application module 1 for adhesive application by the workpiece carrying module 2 set on the rotatable machine base 10; the mounting core 21 provides a precise installation position for the workpiece 5, ensuring that the workpiece 5 is accurately aligned with the linear wiping component 11 when it is moved to the adhesive application module 1; since the workpiece carrying module 2 can rotate under the drive of the workpiece rotation drive module 3, it drives the workpiece 5 to rotate, thereby increasing the wiping area between the workpiece 5 and the linear wiping component 11 and achieving a better adhesive application effect.

[0068] In a preferred embodiment, the workpiece rotation drive module 3 includes a base 31, a fourth drive member 311, and a fifth drive member 32. The fourth drive member 311 is fixed to the base 31, and its output end is connected to a moving part 312. The fifth drive member 32 is fixed to the moving part 312. The fourth drive member 311 drives the fifth drive member 32 to move horizontally towards or away from the lower end of the workpiece support module 2. The output end of the fifth drive member 32 is connected to a main rotating sleeve connector 321. When the fifth drive member 32 moves to align with the lower end of the workpiece support module 2, it drives the main rotating sleeve connector 321 to rotate and contact the secondary rotating sleeve connector 23, thereby driving the workpiece support module 2 to rotate. The fourth drive member 311 can be a cylinder, an electric push rod, a servo motor, or a linear motor, etc., and the fifth drive member 32 can be a rotary motor, a hydraulic motor, or a pneumatic motor, etc.

[0069] Since the fifth driving member 32 can move horizontally under the drive of the fourth driving member 311, the contact position and contact pressure between the main rotating sleeve connector 321 and the secondary rotating sleeve connector 23 can be adjusted for different positions of the workpiece bearing module 2, thereby adapting to workpieces 5 of different specifications and sizes and improving the versatility of the workpiece rotation driving module 3.

[0070] In a preferred embodiment, the residual adhesive recovery module 4 includes a squeezing device 41 and a recovery device 42. The squeezing device 41 includes a third driving member 411 and a squeezing member 412. The third driving member 411 drives the squeezing member 412 to squeeze the residual adhesive on the linear wiping member 11. The recovery device 42 is independently disposed below the squeezing device 41 and is used to recover the residual adhesive and the linear wiping member 11. The third driving member 411 may be a rotary motor, a hydraulic motor, or a pneumatic motor, etc., and the recovery device 42 may be a recovery tank or a collection chamber, etc.

[0071] By incorporating a residual adhesive recovery module 4, which includes a squeezing device 41 and a recovery device 42, the squeezing device 41 can function before the linear wiping member 11 containing residual adhesive falls into the recovery device 42. Specifically, the squeezing device 412 is driven by a third driving member 411 to squeeze the linear wiping member 11, thereby separating the residual adhesive from the linear wiping member 11. As a result, the residual adhesive falling into the recovery device 42 has higher purity, a more regular shape, and is easier to filter and reuse subsequently.

[0072] Preferably, the third driving component 411 is a rotary motor. The output end of the third driving component 411 is connected to a driving gear 4111. A driven gear 4112 is meshed with one side of the driving gear 4111. The driving gear 4111 and the driven gear 4112 are each connected to a pressing component 412 via a rotating shaft. When the third driving component 411 drives the driving gear 4111 to rotate, according to the gear meshing principle, the driven gear 4112 will rotate in the opposite direction to the driving gear 4111, thereby causing the pressing components 412 to rotate relative to each other. The pressing components 412 move closer together, thereby squeezing the linear wiping component 11 with residual adhesive, causing the residual adhesive to separate from the linear wiping component 11 and fall into the recycling device 42. The pressing component 412 can be a roller, pressure roller, bushing, etc.

[0073] Preferably, the extrusion device 41 further includes a fixing device 413 for fixing the linear wiping member 11, the fixing device 413 being disposed directly above the two extrusion members 412. Since the linear wiping member 11 is easily displaced by the force of the extrusion members 412 during the extrusion process, affecting the extrusion effect, the fixing device 413 prevents the linear wiping member 11 from displacing during the extrusion of residual adhesive by the extrusion members 412, ensuring the stability of the linear wiping member 11 during the extrusion process, and thus fully extruding the residual adhesive on the linear wiping member 11. The fixing device 413 can be a bushing or a hollow rod, etc.

[0074] In a preferred embodiment, the linear wiping element 11 is a multi-strand fiber thread. By using a multi-strand fiber thread as the linear wiping element 11, the number of fiber strands in the multi-strand fiber thread constituting the linear wiping element 11 can be freely increased or decreased to adapt to the adhesive removal needs of workpieces 5 of different sizes. The loose structure of the multi-strand fiber thread allows it to penetrate deep into the fine crevices of the workpiece 5 during the wiping process, effectively adsorbing and removing residual adhesive, achieving thorough cleaning of the workpiece 5. The fiber thread can be cotton thread, linen thread, nylon thread, polyester thread, etc. In this embodiment, the number of strands in the multi-strand fiber thread is 6; in other embodiments, the number of strands in the multi-strand fiber thread can be 3, 4, 5, 8, or 10, and no further limitation is made here.

[0075] Preferably, the multi-strand fiber thread is multi-strand cotton thread. Cotton thread has good flexibility and fluffiness, which can better conform to the surface of workpieces 5 of different sizes, and is especially suitable for complex structures with concave or convex surfaces. The cotton thread with a standard binding design can freely increase or decrease the number of cotton threads to meet the adhesive application requirements of workpiece 5, while ensuring the adhesion and adhesive application effect. At the same time, the design of multi-strand cotton thread is convenient to operate, and the residual adhesive adhering to the surface of the cotton thread can be centrally recovered by the residual adhesive recovery module 4, which significantly improves the residual adhesive recovery rate. Multi-strand cotton thread also has strong toughness and is not easy to break during the wiping process. In addition, cotton thread is widely available and inexpensive, making it economical and practical.

[0076] In a preferred embodiment, the automatic adhesive removal and residual adhesive recovery equipment further includes a residual adhesive monitoring device. This device is located on one side of the workpiece carrying module 2 and faces the workpiece 5, and is used to monitor whether residual adhesive is present on the workpiece 5. By setting up the residual adhesive monitoring device, the cleaning level can be effectively controlled, avoiding both over-cleaning that could cause unnecessary damage to the workpiece 5 and insufficient cleaning that could result in residual adhesive remaining on the workpiece 5.

[0077] In a preferred embodiment, the residual adhesive monitoring device includes an industrial camera 61 and an ultraviolet light source (not shown in the figure). The lens field of view of the industrial camera 61 covers the workpiece 5, and the ultraviolet light source is positioned to be aimed at the workpiece 5. Specifically, the industrial camera 61 is disposed outside the guide wheel 121, and its lens field of view covers the workpiece 5; the ultraviolet light source is fixed in the area diagonally above the guide wheel 121, and its irradiation area and the lens field of view of the industrial camera 61 form an overlapping monitoring area on the surface of the workpiece 5; wherein, the industrial camera 61 is configured to determine the presence of residual adhesive by capturing changes in the optical characteristics of the surface of the workpiece 5.

[0078] The industrial camera 61 is used to capture images of the surface of the workpiece 5 in real time, and is selected from a CCD camera or a CMOS camera. Specifically, the adhesive used during the operation contains fluorescent substances, which can produce characteristic fluorescence under ultraviolet light. This fluorescence signal can be captured by the industrial camera 61. Thus, the industrial camera 61, in conjunction with the ultraviolet light source, can acquire fluorescence images of the surface of the workpiece 5. When no fluorescence is observed on the surface of the workpiece 5, that is, when the continuous multi-frame images captured by the industrial camera 61 show no adhesive residue on the workpiece 5, it is determined that there is no residual adhesive on the workpiece 5. At this time, the adhesive wiping is stopped, the first driving component 122 drives the mounting base 12 to move horizontally away from the workpiece bearing module 2, and the machine base 10 rotates to drive the workpiece bearing module 2 away from the adhesive wiping module 1.

[0079] In this embodiment, the industrial camera 61 is fixed on a bracket 62, which is installed at an adjacent workstation of the adhesive application module 1. The bracket 62 drives the industrial camera 61 to rotate via a rotating mechanism (not shown in the figure). The rotation of the bracket 62 allows the lens field of view of the industrial camera 61 to be switched to point towards the workpiece carrying module 2. In other embodiments, the bracket 62 on which the industrial camera 61 is mounted is fixedly installed. The industrial camera 61 is equipped with a wide-angle lens that can simultaneously cover the adjacent workstation area and the workpiece carrying module 2 of the adhesive application module 1. Alternatively, multiple industrial cameras 61 can be installed, with a dedicated industrial camera 61 for monitoring the adhesive application module 1.

[0080] Preferably, the industrial camera 61 is a CCD camera. CCD cameras have high sensitivity and low noise characteristics, and can clearly capture the weak fluorescence signal of adhesive containing fluorescent substances under ultraviolet light excitation and generate images; the excellent image characteristics of CCD cameras enable clear visualization of adhesive residue on the surface of the workpiece 5.

[0081] Preferably, the automatic adhesive wiping and residual adhesive recycling equipment also includes a control system. The control system typically uses a PLC (Programmable Logic Controller) or a PC (Personal Computer) as the control unit. It is connected to the drive devices of each module, the industrial camera 61, and the ultraviolet light source through wired or wireless communication, and controls the automatic operation of each module through the control system.

[0082] The working process of this utility model's automatic glue-wiping and residual glue recycling equipment is as follows:

[0083] The tension adjustment device 13 pulls out the linear wiping component 11 from the linear roller 14. The linear wiping component 11 forms a preset path under the coordinated action of the guide roller 1241 and guide wheel 121 of the auxiliary guide device 124, and is finally guided to the residual adhesive recycling module 4.

[0084] When the machine base 10 rotates and drives the workpiece carrier module 2, on which the workpiece 5 is mounted, to the adhesive wiping module 1, the first driving component 122 drives the mounting base 12 to move horizontally closer to the workpiece carrier module 2, so that the guide wheel 121 drives the linear wiping component 11 to contact the workpiece 5; the second driving component 1231 drives the U-shaped opening clamping component 1232 to press the linear wiping component 11, so that it is tightly attached to the wiping surface of the workpiece 5 through the two pressure arms 12321, and moves longitudinally relative to the wiping surface of the workpiece 5; at the same time, the fourth driving component 311 drives the fifth driving component 32 to move horizontally closer to the lower end of the workpiece carrier module 2 for alignment, so that the main rotating sleeve connector 321 contacts the secondary rotating sleeve connector 23, and the fifth driving component 32 drives the main rotating sleeve connector 321 to rotate, so that the secondary rotating sleeve connector 23 rotates, thereby realizing the rotation of the workpiece carrier module 2, so that the linear wiping component 11 makes multi-dimensional contact with the workpiece 5, and realizes continuous wiping without blind spots.

[0085] During the glue application process, the workpiece 5 maintains its rotation, and the ultraviolet light source fixed above the guide wheel 121 irradiates the surface of the workpiece 5. When the industrial camera 61 captures multiple consecutive frames of images showing no glue residue on the workpiece 5, it is determined that there is no glue residue on the surface of the workpiece 5. At this time, the glue application is stopped, and the first driving component 122 drives the mounting base 12 to move horizontally away from the workpiece bearing module 2. The machine base 10 rotates, causing the workpiece bearing module 2 to move away from the glue application module 1.

[0086] After the adhesive application is completed, the first driving component 122 drives the mounting base 12 to move horizontally away from the workpiece bearing module 2. The partially adhesive-applied linear wiping component 11 moves along a preset path to the residual adhesive recovery module 4, where it is positioned by the fixing device 413. The third driving component 411 drives the extruder 412 to rotate relative to each other through the driving gear 4111 and the driven gear 4112, extruding the linear wiping component 11 with residual adhesive, separating the residual adhesive from the linear wiping component 11 and causing it to fall into the recovery device 42. After extrusion, the linear wiping component 11 continues to feed and eventually falls into the recovery device 42. At the same time, the machine base 10 rotates, causing the workpiece bearing module 2 to move away from the adhesive application module 1.

[0087] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
