A base for a glue-dispensing machine for processing car door handles

Abstract

This application discloses a base for a dispensing machine for processing car door handles, including a base plate with one and two clamps at both ends and the middle of the base plate, respectively. The mounting groove of the crossbeam integrates a clamping, locking, and unlocking assembly, as well as a liftable housing. During operation, the end of the car door handle is placed into the liftable housing. As the door handle is pressed down to lower the liftable housing, the clamping assembly uses a slanted groove and a clamping block to fix the handle. The locking assembly uses an L-shaped locking rod to engage with a locking groove to lock the liftable housing. After dispensing, the unlocking slide rod is pushed, and the unlocking top block acts on the inclined surface of the unlocking rod to release the lock. A spring then pushes the liftable housing upward. The crossbeam adopts a main body-cover plate structure, with a U-shaped protrusion to limit the movement of the liftable housing. Furthermore, the multi-mounting groove design allows multiple components to work simultaneously, enabling the simultaneous processing of multiple car door handles, effectively improving the dispensing accuracy and production efficiency of car door handles. Operation is simple and maintenance is convenient.

Description

Technical Field

[0001] This invention relates to the field of automotive door handle processing equipment technology, specifically to a base for a dispensing machine used in automotive door handle processing. Background Technology

[0002] In the manufacturing process of car door handles, the glue-filling process is a crucial step. As the foundational component of the glue-filling equipment, the structural design of the glue-filling machine base directly impacts the precision and efficiency of the glue-filling process. Existing glue-filling machine bases, when fixing car door handles, have relatively complex structures, are cumbersome to operate, and lack stability. This makes it difficult to ensure the door handle maintains an accurate position during glue-filling, leading to uneven glue application and inconsistent glue quality, thus affecting the processing quality and production efficiency of the car door handles.

[0003] Therefore, there is an urgent need to design a new type of glue-dispensing machine base for processing car door handles to solve the above problems. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art.

[0005] This application provides a base for a glue-dispensing machine for processing car door handles, including a base plate, a clamp at each end of the base plate, and two clamps in the middle of the base plate. Each clamp includes a crossbeam with a mounting groove, the mounting groove penetrating the top surface and one side of the crossbeam. A clamping component, a locking component, an unlocking component, and a liftable housing are installed in the mounting groove. The liftable housing is used to accommodate the end of the car door handle. The clamping component is used to fix the end of the car door handle during the descent of the liftable housing. The locking component is used to lock the liftable housing after the clamping component has fixed the end of the car door handle. The unlocking component is used to release the locking component from locking the liftable housing.

[0006] The clamping assembly includes inclined grooves symmetrically arranged on both sides of the mounting groove. The upper end of the inclined groove is narrower than the lower end. Clamping blocks are slidably inserted through the two side walls of the lifting housing. One end of each clamping block extends into the inclined groove. The end face of the clamping block extending into the inclined groove is inclined and slides in cooperation with the inner wall of the inclined groove.

[0007] The clamping assembly also includes a dovetail groove and a dovetail slider that slide against each other. The dovetail groove is located on the inclined side wall of the inclined groove, and the dovetail slider is located on the end face of the clamping block that extends into the inclined groove.

[0008] The locking assembly includes side plates symmetrically fixed on both sides of the bottom of the lifting housing. Each side plate has a slot on its outer side wall. The bottom of the mounting slot has symmetrical flip slots on both sides. Each flip slot has an L-shaped locking rod rotatably installed in it. The L-shaped locking rod is used to engage with the slot. The unlocking assembly is used to release the L-shaped locking rod from the slot.

[0009] The L-shaped lever includes an unlocking lever and a locking lever that are perpendicularly connected to each other. The connection ends of the unlocking lever and the locking lever are rotatably installed in the flip groove of the mounting slot via a hinge shaft. The unlocking lever is driven by the unlocking component. The locking lever is fixed with a locking block for engaging with the lever slot.

[0010] It also includes a spring disposed between the bottom end of the side plate and the top surface of the unlocking rod, and a positioning cylinder is fixed at the bottom end of each side plate for positioning the spring.

[0011] The unlocking component includes an unlocking slide groove at the bottom of the mounting slot, an unlocking slide rod slidably installed in the unlocking slide groove, and an unlocking top block fixed at the top of the unlocking slide rod; the bottom of the unlocking rod is provided with an unlocking ramp, and the top of the unlocking ramp is provided with a receiving groove; the unlocking ramps on the bottom surfaces of each unlocking rod are parallel to each other, and the unlocking top block slides in cooperation with the unlocking ramp to push the unlocking rod to rotate.

[0012] The unlocking groove runs through both ends of the crossbeam, and one end of the unlocking rod extends out of the crossbeam from the unlocking groove.

[0013] The crossbeam includes a main body and a cover plate; the main body is fixedly mounted on the surface of the base plate, and the cover plate is fixedly installed on the top surface of the main body by fasteners; the mounting groove is defined by the main body and the cover plate, and a U-shaped protrusion is provided at the top of the peripheral wall of the mounting groove corresponding to the cover plate. The cross-sectional shape of the inner circle of the U-shaped protrusion is adapted to the cross-sectional shape of the inner wall of the lifting shell.

[0014] The mounting slots are spaced apart on the crossbeam. The number of clamping components, locking components, unlocking components and lifting shells corresponds to the number of mounting slots and they are installed in each mounting slot.

[0015] The beneficial effects of this invention are as follows:

[0016] This invention, by setting up a liftable lifting shell, a pressing component, a locking component, and an unlocking component, allows the pressing component to automatically fix the end of the door handle during the descent of the lifting shell, and then the locking component to lock the lifting shell, ensuring the stability of the door handle position during the glue-filling process, effectively improving the glue-filling accuracy and quality.

[0017] The cooperation between the inclined groove and the clamping block in the clamping assembly, as well as the setting of the dovetail groove and dovetail slider, makes the clamping process more stable and reliable. The locking and unlocking components are reasonably designed and easy to operate. The lifting shell can be locked and unlocked by simple sliding operation, which reduces the labor intensity of operators and improves work efficiency.

[0018] The crossbeam adopts a structure of main body and cover plate, which facilitates the installation and maintenance of various components; the multiple mounting slots on the crossbeam enable the simultaneous processing of multiple door handles, further improving production efficiency and reducing production costs.

Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0027] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] The following description, in conjunction with the accompanying drawings, details the glue-dispensing machine base for processing car door handles provided in this application through specific embodiments and application scenarios.

[0029] Example 1:

[0030] This application provides a base for a glue-dispensing machine for processing car door handles, including a base plate 1. A clamp 2 is provided at each end of the base plate 1, and two clamps 2 are located in the middle of the base plate 1. Each clamp 2 includes a crossbeam 22 with a mounting groove 21, which penetrates the top surface and one side of the crossbeam 22. A clamping assembly 23, a locking assembly 24, an unlocking assembly 25, and a liftable lifting shell 26 are installed within the mounting groove 21. The lifting shell 26 is used to accommodate the end of the car door handle. The clamping assembly 23 is used to fix the end of the car door handle during the descent of the lifting shell 26. The locking assembly 24 is used to lock the lifting shell 26 after the clamping assembly 23 has fixed the end of the car door handle. The unlocking assembly 25 is used to release the locking assembly 24 from locking the lifting shell 26.

[0031] like Figures 1 to 5 As shown, due to the above structure, during the glue-filling process of the car door handle, the end of the car door handle is first placed inside the lifting housing 26. When it is necessary to fix the car door handle, the car door handle is pressed down, causing the lifting housing 26 to descend. At this time, the clamping component 23, locking component 24, and unlocking component 25 in the mounting slot 21 begin to work together. During the descent of the lifting housing 26, the clamping component 23 and the locking component 24 move synchronously. When the clamping component 23 fixes the end of the car door handle through a specific structure, the locking component 24 locks the lifting housing 26 to prevent it from moving due to external interference during the glue-filling operation, thereby ensuring the stability of the car door handle during the glue-filling process. When the glue-filling is completed and the car door handle needs to be removed, the operator operates the unlocking component 25 to release the locking component 24 from locking the lifting housing 26, allowing the lifting housing 26 to rise and thus smoothly remove the car door handle.

[0032] Example 2:

[0033] The difference from Embodiment 1 is that, in addition to including the structural features of the aforementioned embodiments, the clamping assembly 23 includes inclined grooves 231 symmetrically arranged on both sides of the mounting groove 21. The upper end of the inclined groove 231 is narrower than the lower end. Clamping blocks 232 are slidably inserted through the two side walls of the lifting shell 26. One end of each clamping block 232 extends into the inclined groove 231. The end face of the clamping block 232 extending into the inclined groove 231 is inclined and slides in cooperation with the inner wall of the inclined groove 231.

[0034] In this embodiment of the application, the clamping assembly 23 further includes a dovetail groove 233 and a dovetail slider 234 that slide against each other. The dovetail groove 233 is disposed on the inclined side wall of the inclined groove 231, and the dovetail slider 234 is disposed on the end face of the clamping block 232 that extends into the inclined groove 231.

[0035] like Figures 3 to 4 As shown, due to the aforementioned structure, when the lifting shell 26 begins to descend under the action of the lifting drive device, the clamping blocks 232 on both sides of the lifting shell 26 descend along with the lifting shell 26. Due to the special structure of the inclined groove 231, which is narrow at the top and wide at the bottom, and the inclined end face of the clamping block 232 extending into the inclined groove 231, which is inclined and slides in cooperation with the inner wall of the inclined groove 231, during the descent, as the descent distance of the lifting shell 26 increases, the inner wall of the inclined groove 231 will generate an inward component force on the clamping block 232, pushing the clamping block 232 towards the door handle, thereby pressing the end of the door handle tightly and fixing the door handle. At the same time, the mutual sliding cooperation of the dovetail groove 233 and the dovetail slider 234 restricts the movement of the clamping block 232 in the direction perpendicular to the inclined groove 231, ensuring the stability and accuracy of the movement of the clamping block 232 in the inclined groove 231, ensuring that the clamping process can be carried out reliably and stably, and even if the equipment vibrates slightly during the glue pouring process, it can maintain the effective fixation of the door handle.

[0036] Example 3:

[0037] The difference from Embodiment 2 is that, in addition to including the structural features of the aforementioned embodiments, the locking assembly 24 includes side plates 241 symmetrically fixed on both sides of the bottom of the lifting shell 26. Each side plate 241 has a slot 242 on its outer side wall. The mounting slot 21 has symmetrical flip slots 243 on both sides of its bottom. Each flip slot 243 has an L-shaped locking rod 244 rotatably installed in it. The L-shaped locking rod 244 is used to engage with the slot 242. The unlocking assembly 25 is used to release the engagement between the L-shaped locking rod 244 and the slot 242.

[0038] In this embodiment of the application, the L-shaped locking lever 244 includes an unlocking lever 2441 and a locking lever 2442 that are perpendicularly connected to each other. The connecting ends of the unlocking lever 2441 and the locking lever 2442 are rotatably installed in the flip groove 243 of the mounting groove 21 via a hinge shaft. The unlocking lever 2441 is in transmission cooperation with the unlocking component 25. The locking lever 2442 is fixedly provided with a locking block 2443 for engaging with the locking groove 242.

[0039] In this embodiment of the application, a spring 3 is also provided between the bottom end of the side plate 241 and the top surface of the unlocking rod 2441. A positioning cylinder 4 is fixed at the bottom end of each side plate 241 for positioning the spring 3.

[0040] like Figures 3 to 4As shown, due to the aforementioned structure, during the descent of the lifting shell 26, the clamping assembly 23 gradually secures the end of the door handle. Simultaneously, the bottom of the side plate 241 gradually approaches the top surface of the unlocking lever 2441, and the spring 3 begins to compress, storing elastic potential energy. As the lifting shell 26 descends further, the bottom surface of the side plate 241 contacts the inclined top surface of the locking block 2443. Due to the downward pressure of the side plate 241, the locking block 2443 is pushed, causing the unlocking lever 2441 and the locking lever 2442 to rotate around the pivot. The locking lever 2442, along with the locking block 2443, gradually enters the flipping groove 243. The free end of the unlocking lever 2441 rises, further compressing the spring 3, which further shortens until the slot 242 aligns with the locking block 2443. At this point, the elastic potential energy of the spring 3 reaches a certain level, and the spring 3 releases its elastic potential energy, pushing the unlocking lever 2441 and the locking lever 2442 to reverse around the pivot, thus unlocking the door. The bottom surface of rod 2441 abuts against the bottom surface of mounting groove 21, and the locking rod 2442 abuts against the side wall of mounting groove 21 and side plate 241. The locking block 2443 is precisely inserted into the slot 242. Due to the continuous elastic pressure provided by spring 3, the locking block 2443 and slot 242 are firmly engaged and will not loosen due to external forces such as vibration during the glue-pouring process. At this time, the clamping assembly 23 completely completes the fixation of the end of the door handle. When it is necessary to release the fixation of the door handle, the operator operates the unlocking assembly 25 and pushes the unlocking rod 2441 to rotate around the hinge shaft with the locking rod 2442. The locking rod 2442 and the locking block 2443 enter the flip groove 243 again, and the locking block 2443 disengages from the slot 242. At this time, spring 3 releases the remaining elastic potential energy, pushing the side plate 241 and the lifting shell 26 to rise. At the same time, the clamping assembly 23 will also release the fixation of the end of the door handle due to the rise of the lifting shell 26.

[0041] Example 4:

[0042] The difference from Embodiment 3 is that, in addition to including the structural features of the aforementioned embodiments, the unlocking component 25 includes an unlocking slide groove 251 disposed at the bottom of the mounting groove 21, an unlocking slide rod 252 slidably mounted in the unlocking slide groove 251, and an unlocking top block 253 fixedly disposed at the top of the unlocking slide rod 252; the bottom of the unlocking rod 2441 is provided with an unlocking inclined surface 254, and the top of the unlocking inclined surface 254 is provided with a receiving groove 255, the unlocking inclined surfaces 254 on the bottom surface of each unlocking rod 2441 are parallel to each other, and the unlocking top block 253 slides in cooperation with the unlocking inclined surface 254 to push the unlocking rod 2441 to rotate.

[0043] In this embodiment of the application, the unlocking groove 251 passes through both ends of the crossbeam 22, and one end of the unlocking rod 252 extends out of the crossbeam 22 from the unlocking groove 251.

[0044] like Figures 3 to 5As shown, due to the above structure, when the glue is applied and the lifting shell 26 needs to be unlocked, the operator pushes the end of the unlocking slide rod 252 extending out of the crossbeam 22 into the unlocking groove 251. At this time, the unlocking top block 253 at the top of the unlocking slide rod 252 first slides from the receiving groove 255 into the unlocking inclined surface 254, and gradually slides down along the unlocking inclined surface 254 at the bottom of the unlocking rod 2441. Since the unlocking inclined surfaces 254 at the bottom of each unlocking rod 2441 are parallel to each other, the unlocking top block 253 will generate a horizontal component force on the unlocking rod 2441 during the sliding process, pushing the unlocking rod 2441 to rotate around the hinge shaft. As the unlocking top block 253 slides to the lower end of the unlocking inclined surface 254, the unlocking rod 2441 drives the upper locking rod 2442 to rotate, thereby causing the locking blocks 2443 on each upper locking rod 2442 to disengage from the locking groove 242 of the side plate 241, and simultaneously enter the flipping state. Inside the slot 243, the engagement between the slot 242 and the block 2443 is successfully released, unlocking the lifting shell 26. During the unlocking process, each spring 3 releases elastic potential energy to push the lifting shell 26 upward. During this process, the other end of the unlocking slide rod 252 will gradually extend beyond the other end of the unlocking slide groove 251. When the lifting shell 26 rises to a certain position, making the slot 242 higher than the block 2443, the operator pushes the end that is now extending into the unlocking slide groove 251 back into the unlocking slide groove 251, causing the unlocking top block 253 at the top of the unlocking slide rod 252 to slide from the lower end of the unlocking slope 254 to the corresponding receiving groove 255. Under the action of the spring 3, the unlocking rod 2441 and the locking rod 2442 rotate around the pivot to reset, the receiving groove 255 and the unlocking top block 253 come into contact with each other, and the block 2443 re-extends into the mounting groove 21, preparing for the next locking operation.

[0045] Example 5:

[0046] The difference from Embodiment 4 is that, in addition to the structural features of the aforementioned embodiments, the crossbeam 22 includes a main body 221 and a cover plate 222; the main body 221 is fixedly disposed on the surface of the base plate 1, and the cover plate 222 is fixedly installed on the top surface of the main body 221 by fasteners; the mounting groove 21 is defined by the main body 221 and the cover plate 222, and a U-shaped protrusion 223 is provided at the top of the peripheral wall of the mounting groove 21 corresponding to the cover plate 222, and the inner cross-sectional shape of the U-shaped protrusion 223 is adapted to the inner cross-sectional shape of the lifting shell 26.

[0047] like Figure 1 and Figure 3As shown, due to the above-mentioned structure, the crossbeam 22 adopts a split structure of main body 221 and cover plate 222. The main body 221 is fixed to the surface of the base plate 1 by welding, bolt connection, etc., and the cover plate 222 is installed on the top surface of the main body 221 by fasteners (such as bolts, screws, etc.). This structural design greatly facilitates the installation, debugging and maintenance of various components in the mounting groove 21. During the lifting process of the lifting shell 26, when the top surface of the lifting shell 26 contacts the bottom surface of the U-shaped protrusion 223, the U-shaped protrusion 223 can play a precise limiting role for the lifting shell 26 because the cross-sectional shape of the inner ring of the U-shaped protrusion 223 matches the cross-sectional shape of the inner wall of the lifting shell 26. This prevents the lifting shell 26 from falling out of the mounting groove 21 during the lifting process, ensuring the positional accuracy and stability of the lifting shell 26 throughout the entire operation.

[0048] Meanwhile, when installing or disassembling components such as the lifting shell 26, the inside of the mounting slot 21 can be quickly accessed by removing the cover plate 222, which improves the convenience of equipment maintenance.

[0049] Example 6:

[0050] The difference from Embodiment 5 is that, in this embodiment, in addition to including the structural features of the aforementioned embodiments, a plurality of mounting slots 21 are provided at intervals on the crossbeam 22, and the number of pressing components 23, locking components 24, unlocking components 25 and lifting shells 26 corresponds to the number of mounting slots 21 and are installed in each mounting slot 21.

[0051] like Figures 1 to 2 As shown, due to the above structure, multiple mounting slots 21 are spaced apart on the crossbeam 22, and each mounting slot 21 is equipped with a set of independently working clamping components 23, locking components 24, unlocking components 25 and lifting shell 26.

[0052] In actual production, operators can simultaneously place the ends of multiple door handles into each lifting shell 26, and then press the door handle to make the corresponding lifting shell 26 descend synchronously. The pressing components 23 and locking components 24 in each mounting slot 21 fix and lock the corresponding door handles in sequence according to the operating logic of the aforementioned embodiment. After the glue-filling process is completed, since the unlocking slide grooves 251 in each unlocking component 25 on the same crossbeam 22 are interconnected, and the adjacent ends of each unlocking slide rod 252 abut or are fixed to each other, the operator only needs to push the outermost unlocking slide rod 252 to extend one end outside the crossbeam 22 to drive all unlocking slide rods 252 to slide synchronously, so that all unlocking top blocks 253 act on the corresponding unlocking rods 2441 at the same time, thereby realizing the synchronous unlocking of all lifting shells 26.

[0053] Afterwards, each lifting shell 26 rises synchronously under the action of the corresponding spring 3, and the operator can take out multiple door handles that have been glued at one time. This design can process multiple door handles at one time, which greatly improves production efficiency compared to processing them individually. At the same time, due to the independent and precise design of each component, the fixing effect and glue quality of each door handle during the glue-filling process are also guaranteed.
