Description

Technical Field

[0001] This utility model relates to the field of glue injection station technology, specifically to an adjustable multi-nozzle glue injection nozzle. Background Technology

[0002] In industrial production, a dispensing machine is a device that precisely coats or injects adhesive into a designated location on a workpiece using dispensing nozzles. Multiple dispensing nozzles can work simultaneously, greatly improving the dispensing efficiency for multiple workpieces or multiple points on a workpiece. It is a common configuration in batch dispensing production, and its performance directly affects the accuracy and efficiency of the dispensing operation.

[0003] However, existing multi-nozzle dispensing equipment still has many shortcomings in practical applications: most equipment uses the method of driving the dispensing head to move back and forth and up and down to adjust the dispensing position. This adjustment method requires the additional setting of multiple sets of horizontal and vertical drive structures. On the one hand, the positioning accuracy of the dispensing head is easily reduced due to the matching error between the drive structures, resulting in problems such as dispensing deviation and uneven dispensing volume. This is especially obvious in micro-workpieces or dense dispensing scenarios. On the other hand, the multiple sets of structures required for the movement of the dispensing head not only increase the overall complexity of the equipment, but also easily cause instability problems due to the excessive number of parts, such as shaking and jamming during the movement, which further affects the dispensing quality. At the same time, if a reinforcement structure is added to improve stability, it will lead to a significant increase in the equipment manufacturing and maintenance costs, which is not conducive to controlling production input. In addition, the loading and unloading areas of existing equipment often interfere with the movement path of the dispensing head, or require frequent manual adjustment of the workpiece position, which makes the loading and unloading operations inconvenient, affects the overall operation efficiency, and makes it difficult to meet the needs of efficient and accurate batch dispensing. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable multi-nozzle dispensing nozzle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An adjustable multi-nozzle dispensing nozzle includes: The workbench has a feeding area at the front end, a first adjustment component installed in the feeding area, a second adjustment component installed at the rear end, and a dripping adhesive recovery component installed in the cavity at the bottom of the workbench. The first adjustment component includes a first guide rail, on which a carrier plate with a workpiece frame is slidably connected via a slider. The carrier plate can move along the length of the first guide rail to adjust the lateral position of the workpiece on the carrier plate. When the carrier plate moves along the first guide rail to the loading area, it can avoid interference with other components of the worktable and load the workpiece without interference. When it moves to the bottom of the second adjustment component, it can align the workpiece with the glue injection operation area. The second adjustment component includes a second guide rail, which is symmetrically fixedly connected to both sides of the dispensing machine, and the second guide rail is slidably connected to a pre-set guide groove on the guide seat; The dispensing machine can move stably along the guide groove. With the help of the precise cooperation between the second guide rail and the guide groove, the positional accuracy of the dispensing machine during movement is ensured.

[0006] Preferably, the first adjustment component further includes a second cylinder, which is horizontally fixedly connected to the lower end face of the front end of the worktable along the length direction of the first guide rail. The front end of the piston rod of the second cylinder is fixedly connected to a horizontally set connecting plate. The connecting plate is fixedly connected to the front end face of the moving block. The top end of the moving block is fixedly connected to the lower end face of the carrier plate. A strip-shaped moving groove is opened in the middle of the worktable along the length direction of the first guide rail. The moving block is inserted into the moving groove and can only slide along the length direction of the moving groove to achieve lateral limitation of the moving block.

[0007] Preferably, the upper rear end face of the carrier plate has a groove, and a workpiece frame is installed in the groove by bolts.

[0008] Preferably, the second adjustment component further includes a third cylinder, which is arranged vertically and its top is fixedly connected to the lower end face of the second guide plate. The piston rod of the third cylinder passes through the second guide plate and is fixedly connected to the lower end face of the second lifting block. A third guide rod is fixedly connected to the lower end face of the second lifting block and passes through the second guide plate. Preferably, the two sides of the second guide plate are fixedly connected to the upper end face of the worktable by corner connectors. One side of the corner connector is bolted to the side of the second guide plate, and the other side is bolted to the table surface of the worktable.

[0009] Preferably, the front end face of the second lifting block is fixedly attached to the rear end face of the dispensing machine, and the two are detachably connected by bolts. Multiple dispensing nozzles are spaced apart at the bottom of the dispensing machine. Each dispensing nozzle corresponds to and is connected to the dispensing channel of the dispensing machine. The diameter of the dispensing nozzle can be changed according to the dispensing requirements. Multiple dispensing nozzles can simultaneously perform dispensing operations on multiple workpieces on the carrier plate, thereby improving dispensing efficiency.

[0010] Preferably, the guide seat is an inverted "L" shape, integrally formed from a horizontal section and a vertical section. The lower end of the vertical section is fixed to the upper surface of the worktable. The front end of the horizontal section has a guide groove along the length direction. The guide groove is "T" shaped and is adapted to the size of the second guide rail. The second guide rail can be inserted into the groove and slide.

[0011] Preferably, the dripping adhesive recovery assembly includes a first cylinder, a first guide plate, a first lifting block, a first guide rod, a second guide rod, a placement plate, and a collection frame. The first guide plate is fixed to the upper end face of the first cylinder, and the first cylinder is fixedly connected to the upper end face of the base. The top end of the piston rod of the first cylinder is fixedly connected to the lower end face of the first lifting block. A concave placement plate is fixedly connected to the top of the first lifting block. The collection frame is placed on the upper end face of the placement plate, and the opening of the collection frame faces upward and corresponds to the adhesive injection operation area.

[0012] Preferably, the first guide rod is fixedly connected to the lower end face of the workbench, and the first guide rod vertically passes through both sides of the first lifting block. The second guide rod is fixedly connected to the lower end face of the first lifting block, and the first lifting block vertically passes through the first guide plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention, by setting a first adjustment component, can drive the carrier plate to move precisely along the length of the worktable, realizing the seamless switching of the workpiece from the loading area to the glue injection operation area. At the same time, with the double limiting of the moving groove and the first guide rail, the lateral displacement of the carrier plate is avoided, ensuring that the workpiece can be accurately aligned with the glue injection nozzle below the glue injection machine, laying the foundation for subsequent accurate glue injection, and effectively solving the glue injection misalignment problem caused by workpiece positioning deviation in traditional equipment.

[0014] This invention, by setting a second adjustment component, uses a third cylinder and a third guide rod to drive the dispensing machine to rise and fall vertically, achieving flexible adjustment of the distance between the dispensing nozzle and the workpiece. Furthermore, through the precise engagement of the second guide rail and the "T"-shaped guide groove of the guide seat, a double-sided limit is formed, which, together with the third guide rod, constitutes a double guiding constraint, preventing the dispensing machine from shaking or shifting laterally due to the force on the cantilever during lifting and lowering. This ensures that the dispensing nozzle is always accurately aligned with the dispensing point on the workpiece, improving dispensing accuracy and making it suitable for micro-workpieces and intensive dispensing scenarios.

[0015] This invention, by setting up a drip recovery component, allows the collection frame to rise and connect to the through groove when the equipment is not in operation, catching the glue that drips naturally from the dispensing nozzle; when in operation, the collection frame descends to make way for the carrier plate, which not only prevents glue from dripping and contaminating the work surface or cavity, reducing glue waste, but also ensures the stability of the collection frame through the limiting effect of the "concave" shaped placement plate, ensuring the reliability of the drip recovery process, improving glue utilization and equipment cleanliness.

[0016] This invention, through the coordinated operation of the first adjustment component, the second adjustment component, and the electrical control system, can achieve automated connection of feeding, workpiece shifting, dispensing machine lifting, dispensing operation, and drip recycling, reducing manual intervention, improving the continuity and efficiency of the overall dispensing operation, avoiding the impact of human operation errors on dispensing quality, and ensuring the consistency of dispensing quality during mass production.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Please see Figures 1 to 8 This utility model provides a technical solution: An adjustable multi-nozzle dispensing nozzle includes a worktable 1. The front end of the worktable 1 is designated as an independent feeding area 4, where a first adjustment component is installed without any other interfering parts. This area is specifically designed for the initial placement and positioning of workpieces. The rear end of the worktable 1 is the core area for dispensing operations, where a second adjustment component is installed to drive the dispensing machine 10 to operate precisely. At the same time, a cavity 2 structure is reserved at the bottom of the worktable 1. A drip recovery component is installed in the cavity 2 to collect the drips generated by the dispensing nozzle 11, avoiding waste of adhesive and contamination of the worktable 1.

[0021] like Figure 4 As shown, the first adjustment assembly includes a first guide rail 5, a second cylinder 9, a carrier plate 7, a slider 6, and a workpiece frame 8. The first guide rail 5 is horizontally fixed along the length of the worktable 1. The bottom of the carrier plate 7 is slidably connected to the first guide rail 5 via the slider 6. The precise fit between the slider 6 and the guide rail ensures the straightness of the carrier plate 7 during movement. A groove adapted to the workpiece frame 8 is provided on the upper end face of the rear end of the carrier plate 7. The workpiece frame 8 is detachably installed in the groove by bolts, which not only ensures the stability of the workpiece frame 8 during the movement of the carrier plate 7, but also facilitates the replacement of workpiece frames 8 of different specifications according to the workpiece size, thereby improving the adaptability of the equipment.

[0022] The second cylinder 9 is horizontally fixed to the lower end face of the front end of the worktable 1 along the length of the first guide rail 5 by bolts or a cylinder bracket (e.g., Figure 5 As shown), the front end of its piston rod is fixedly connected to the horizontally arranged connecting plate 901, the other end of the connecting plate 901 is connected to the front end face of the moving block 701 by bolts, and the top end of the moving block 701 is fixed to the lower end face of the carrier plate 7; correspondingly, a strip-shaped moving groove 101 is provided in the middle of the worktable 1 along the length direction of the first guide rail 5, and the moving block 701 is inserted into the moving groove 101 and can only slide along the length direction of the groove.

[0023] In this embodiment, when the piston rod of the second cylinder 9 extends or retracts, the connecting plate 901 can drive the moving block 701 to slide along the moving groove 101, thereby driving the carrier plate 7 to move along the first guide rail 5. This not only realizes the switching of the workpiece from the position below the second adjustment component in the loading area 4, but also, through the limiting effect of the moving groove 101 on the moving block 701 and in conjunction with the first guide rail 5, prevents lateral displacement of the carrier plate 7 during movement, thus ensuring the positioning accuracy of the workpiece.

[0024] It should be noted that the basic structural form of the workpiece frame 8 belongs to existing related technologies. Its core function is to provide an independent placement and positioning space for the workpiece to be glued. Therefore, the interior of the workpiece frame 8 is pre-divided into independent areas corresponding to the number of glue dispensing heads below the glue dispensing machine 10. Each area can hold one workpiece to be processed, ensuring that each glue dispensing head can accurately align with the workpiece in the corresponding area during operation, realizing simultaneous glue dispensing of multiple workpieces. At the same time, the overall shape of the workpiece frame 8 and the size and layout of its internal areas are not fixed, but are adapted to the shape and size of the workpiece to be processed. When production needs change (such as changing to workpieces of different specifications and shapes to be glued), the original workpiece frame 8 can be removed and replaced with a special workpiece frame 8 adapted to the new workpiece by disassembling the bolts connecting the workpiece frame 8 to the groove of the carrier plate 7. It has strong flexibility and adaptability, meeting diverse glue dispensing production needs. This part of the structure does not require additional innovative design. In this embodiment, it is only by detachably connecting it to the carrier plate 7 that the overall production adaptability efficiency of the equipment is further improved.

[0025] The second adjustment component, used to drive the dispensing machine 10 to achieve vertical lifting, includes a second guide rail 18 and a guide seat 17. The guide seat 17 is an inverted "L"-shaped integrally molded structure; its lower vertical section is fixed to the upper surface of the worktable 1, and its front horizontal section has a "T"-shaped guide groove 1701 (e.g., ...). Figure 7 As shown), the guide seats 17 are fixed to the two sides of the worktable 1 at the rear end by bolts; the length of the guide groove 1701 is adapted to the lifting stroke required by the dispensing machine 10, and the groove wall is smooth and precision polished to ensure smoothness in the guiding process.

[0026] It should be noted that the second guide rail 18 is a long strip structure adapted to the "T"-shaped guide groove 1701, and its cross-sectional dimensions are perfectly matched with the guide groove 1701. The second guide rail 18 is fixed vertically to both end faces of the second lifting block 12 (corresponding to the guide seat 17). The front end face of the second lifting block 12 is fixedly attached to the rear end face of the dispensing machine 10. Therefore, the second guide rail 18 forms an integrated structure with the second lifting block 12 and the dispensing machine 10. During assembly, the second guide rail 18 is embedded in the "T"-shaped guide groove 1701 of the guide seat 17 and can only slide vertically along the groove, without any lateral offset.

[0027] The second adjustment assembly also includes a third cylinder 13 and a second guide plate 14, the second guide plate 14 having a concave structure (e.g., Figure 3As shown in the figure, the second guide plate 14 is fixed to the upper surface of the worktable 1 on both sides by corner connectors 15. One side of the corner connector 15 is bolted to the side of the second guide plate 14, and the other side is bolted to the table surface of the worktable 1. The double fixation ensures the stability of the second guide plate 14. The third cylinder 13 is set in a vertical position. Its top is fixed to the lower surface of the second guide plate 14, and the piston rod passes through the second guide plate 14 downward and is fixed to the upper surface of the second lifting block 12. There are two third guide rods 16, which are symmetrically distributed on both sides of the third cylinder 13. The lower surface of the second lifting block 12 is fixedly connected to the third guide rod 16, and the third guide rod 16 passes through the second guide plate 14. The front end of the second lifting block 12 is fixedly attached to the rear end of the dispensing machine 10 and is detachably connected by bolts.

[0028] In this embodiment, when the piston rod of the third cylinder 13 extends or retracts, it drives the second lifting block 12 to move vertically in conjunction with the third guide rod 16, thereby driving the glue dispensing machine 10 fixed thereto to rise and fall synchronously, so as to achieve precise adjustment of the distance between the glue dispensing nozzle 11 and the workpiece. However, since the glue dispensing machine 10 itself has multiple glue dispensing channels and glue dispensing nozzles 11, there is a certain weight distribution. And the second lifting block 12 is only connected to the third cylinder 13 and the third guide rod 16 through the rear end. After the front end carries the glue dispensing machine 10, it is easy to cause slight shaking due to the force on the front cantilever during the lifting process, or slight lateral displacement due to the fit gap between the third guide rod 16 and the second guide plate 14. This may cause the glue dispensing nozzle 11 to be unable to always accurately align with the glue dispensing point of the workpiece, resulting in problems such as glue dispensing deviation and uneven glue volume. Therefore, in the glue dispensing machine The second guide rail 18 is fixedly installed on both sides of the guide seat 17 at the rear end of the worktable 1. The second guide rail 18 is precisely fitted with the "T"-shaped guide groove 1701 opened at the front end of the horizontal section of the guide seat 17. When the dispensing machine 10 is raised and lowered, the second guide rail 18 slides vertically along the guide groove 1701 to form a double-sided limit. Together with the third guide rod 16, it forms a double guide constraint, which effectively avoids the shaking and lateral deviation of the dispensing machine 10 and ensures that the dispensing nozzle 11 is always accurately aligned. This not only improves the dispensing accuracy and is suitable for micro workpieces or dense dispensing scenarios, but also disperses the lateral force, reduces the unilateral load of the third cylinder 13 and the third guide rod 16, reduces component wear, and at the same time avoids the dispensing channel inside the dispensing machine 10 from being left or blocked due to shaking, thus extending the equipment maintenance cycle and service life.

[0029] It should be noted that multiple dispensing nozzles 11 are spaced apart along the length of the dispensing machine 10. These nozzles 11 are connected to the dispensing channels inside the dispensing machine 10, and are detachable, allowing for flexible replacement of their diameters according to the dispensing requirements of the workpiece. During operation, multiple nozzles 11 can simultaneously dispense adhesive onto multiple workpieces on the carrier plate 7, significantly improving dispensing efficiency. The basic structural form of the multi-nozzle dispensing nozzles 11 and the matching dispensing machine 10 has been disclosed in existing related technologies. For example, the internal pipeline layout for conveying adhesive, the valve assembly for controlling the flow of adhesive, and the power unit for driving adhesive extrusion are all conventional technical content that can be obtained by those skilled in the art from existing public information and are not the innovation of this utility model; therefore, they need not be described in detail here.

[0030] The adhesive dripping recovery assembly is installed in the cavity 2 at the bottom of the workbench 1 to collect excess adhesive dripping during the dispensing process. The first cylinder 201 is vertically fixed to the upper surface of the base 3, and the first guide plate 202 is horizontally fixed to the upper surface of the first cylinder 201 (e.g., ...). Figure 8 (As shown); the top end of the piston rod of the first cylinder 201 is fixedly connected to the lower end face of the first lifting block 203, and the first lifting block 203 can be driven to move up and down by the extension and retraction of the piston rod.

[0031] The first guide rod 204 is vertically fixed to the lower end face of the workbench 1, and the first guide rod 204 vertically passes through both sides of the first lifting block 203 (e.g., ...). Figure 8 As shown, the lifting direction of the first lifting block 203 is laterally limited; the second guide rod 205 is vertically fixed to the lower end face of the first lifting block 203 and penetrates the first guide plate 202 vertically, further limiting the swaying of the first lifting block 203 and ensuring the stability of the lifting process.

[0032] The top of the first lifting block 203 is fixedly connected to a concave placement plate 206. The concave structure of the placement plate 206 can position the collection frame 207 and prevent the collection frame 207 from shifting during movement. The collection frame 207 is placed on the upper surface of the placement plate 206, with its opening facing upward and corresponding to the glue injection operation area at the rear end of the worktable 1.

[0033] In this embodiment, a through-slot is provided below the workbench 1 corresponding to the glue injection operation area (i.e., the work area). The size of the through-slot is adapted to the opening size of the collection frame 207, and the position of the opening of the collection frame 207 corresponds vertically to the position of the through-slot. When the equipment is not in operation (such as standby, workpiece replacement, or equipment debugging), the glue injection nozzle 11 may drip glue naturally. At this time, the first cylinder 201 in the glue drip recovery component is activated, driving the first lifting block 203 to rise along the first guide rod 204, driving the second guide rod 205 to rise and fall within the first guide plate 202, and simultaneously driving the placement plate 206 and the collection frame 207 to rise until the opening of the collection frame 207 is precisely aligned with the edge of the through-slot at the bottom of the workbench 1. The glue dripping naturally from the glue injection nozzle 11 can fall directly into the through-slot. Inside the collection frame 207, adhesive drips are effectively prevented from falling onto the workbench 1 or the bottom cavity 2, thus preventing contamination and ensuring the cleanliness of the equipment. When the equipment enters the working state and the carrier plate 7 is about to move to the working area under the drive of the first adjustment component, the first cylinder 201 drives the first lifting block 203 to move the collection frame 207 vertically downward, causing the collection frame 207 to fall back into the bottom cavity 2 of the workbench 1, making room for the movement path of the carrier plate 7, avoiding interference between the collection frame 207 and the carrier plate 7, and ensuring that the carrier plate 7 can move smoothly to the working area to complete the workpiece adhesive injection operation.

[0034] It should be noted that the placement plate 206 has a concave structure, and the height of the vertical baffles on both sides is designed so that when the collection frame 207 is placed in the concave area of ​​the placement plate 206, the vertical baffles on both sides can form a barrier from the left and right sides of the collection frame 207, stably confining the collection frame 207 within the concave area of ​​the placement plate 206. Even if there is slight vibration due to the lifting and lowering of the first lifting block 203 during equipment operation, or if the weight of the adhesive in the collection frame 207 changes, the higher baffles on both sides can effectively prevent the collection frame 207 from shifting or slipping off the placement plate 206, ensuring that the collection frame 207 is always directly below the through groove, thus ensuring the stability of the adhesive recycling process.

[0035] In this embodiment, the start / stop and dispensing volume control of the second cylinder 9 of the first adjustment component, the third cylinder 13 of the second adjustment component, the first cylinder 201 of the dispensing recovery component, and the dispensing machine 10 are all automated and coordinated through an external electrical control system, such as a PLC controller. This allows for precise control of the extension and retraction stroke and speed of each cylinder piston rod, and the working sequence of the dispensing machine 10, based on preset dispensing process parameters, ensuring the orderly connection of actions such as feeding, shifting, dispensing, and recycling. The hardware components (such as controllers, sensors, relays, etc.) and software control logic of the electrical control system are existing related technologies and have been disclosed. These are technical contents that can be implemented by those skilled in the art based on conventional automated control methods, and are not the innovative points of this utility model; therefore, they need not be elaborated here.

[0036] In use, this utility model first selects a suitable workpiece frame 8 and glue nozzle 11 according to the specifications of the workpiece to be processed and the glue injection requirements. The workpiece frame 8 is installed in the groove of the carrier plate 7 with bolts. After replacing the glue nozzle 11 below the glue injection machine 10, the workpieces to be glued are placed one by one into the independent area of ​​the workpiece frame 8 to complete the loading. Then, the second cylinder 9 of the first adjustment component is activated. The piston rod extends and retracts, driving the moving block 701 to slide along the strip moving groove 101 of the worktable 1. This drives the carrier plate 7 to move from the upper area to the glue injection operation area at the rear end of the worktable 1 via the slider 6 along the first guide rail 5. During this period, the first cylinder 201 of the glue drip recovery component drives the collection frame 207 to descend into the cavity 2 to make way for the carrier plate 7, ensuring that the carrier plate 7 is accurately positioned directly below the glue injection machine 10.

[0037] Next, the third cylinder 13 of the second adjustment component is activated. The piston rod extends and retracts, driving the second lifting block 12 to move vertically along the third guide rod 16 and the second guide rail 18 (which cooperates with the "T"-shaped guide groove 1701 of the guide seat 17). This drives the dispensing machine 10 to adjust its height so that the dispensing nozzle 11 maintains a suitable distance from the workpiece surface. Then, the dispensing machine 10 is activated, and multiple dispensing nozzles 11 simultaneously perform dispensing operations on the workpiece in the workpiece frame 8. If excess adhesive drips during the operation, it can be temporarily stored through the through groove of the worktable 1 (when not in operation, the collection frame 207 rises to receive the naturally dripping adhesive).

[0038] After the glue injection is completed, the third cylinder 13 drives the glue injection machine 10 to rise and reset, and the second cylinder 9 drives the carrier plate 7 to move from the glue injection operation area back to the loading area 4 to remove the processed workpiece. If continuous operation is required, the above loading, moving, and glue injection steps are repeated. When the glue in the collection frame 207 accumulates to a certain amount, the collection frame 207 can be lowered and taken out from the cavity 2 for cleaning. After cleaning, it is put back into the placement plate 206.

[0039] All other parts of this utility model not described herein are the same as existing technologies, or are known technologies, or can be implemented using existing technologies, and will not be described in detail here.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
