Description

Technical Field

[0001] This utility model relates to the field of lamp housing processing technology, specifically to a lamp housing feeding mechanism for a three-station glue station. Background Technology

[0002] In the field of lamp housing manufacturing, an adhesive application station is a specialized piece of equipment used for applying adhesive to lamp housings. Its core function is to seal, fix, or connect the lamp housing to other components (such as lamp shades, sealing rings, etc.) by precisely applying adhesive. The adhesive application process is crucial to the subsequent assembly quality and performance of the lamp housing: on the one hand, a uniform and continuous adhesive layer ensures the sealing performance of the lamp housing, preventing problems such as water or air leakage during use; on the other hand, appropriate adhesive amount and application location ensure connection strength, preventing damage to the lamp housing due to component detachment during transportation and use. Therefore, the quality of adhesive application directly affects the overall quality and service life of the lamp housing.

[0003] Currently, in the lamp housing feeding structure of glue stations, some feeding mechanisms use manual pushing or simple slide rail feeding, lacking precise positioning and guiding structures. This causes the lamp housing to easily shift and shake during feeding, affecting the gripping accuracy of the subsequent mechanical gripper and the accuracy of the glue application position. Some feeding mechanisms have poor matching between the power components and the load-bearing structure, resulting in insufficient operational stability. Vibration can easily cause the lamp housing to shift, and the feeding speed and stroke control accuracy are low, making it difficult to match the automated processing rhythm of the glue station. In addition, most feeding mechanisms are not equipped with effective cable protection and static electricity elimination devices. Cables are prone to tangling and wear due to frequent movement, and static electricity on the lamp housing surface can attract dust and impurities, affecting the glue application quality. At the same time, maintenance is inconvenient, increasing equipment downtime and production costs. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lamp housing feeding mechanism for a three-station glue station includes:

[0007] A machine frame, wherein a table is fixedly connected to the upper end surface of the machine frame, and a slide assembly is provided above the table.

[0015] Preferably, the electrostatic gun assembly includes a mounting frame and an electrostatic gun, the mounting frame being vertically fixed to the table surface, and the electrostatic gun being installed inside the mounting frame.

[0016] Preferably, the front end of the machine frame is provided with a maintenance door, which is rotatably connected to the machine frame via a hinge, and the maintenance door is provided with a handle.

[0017] Preferably, the length of the guide rail is greater than the length of the rodless cylinder, and the two guide rails are symmetrically distributed about the axis of the rodless cylinder.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention achieves smooth linear motion of the lamp housing slide by using a rodless cylinder in conjunction with a guide rail. It features high motion accuracy, fast response speed, and stable output force, and can precisely control the slide's movement speed and start / stop, meeting the requirements for feeding position accuracy.

[0020] This utility model, by setting up a lamp housing fixture with multiple clamps, can form multi-point positioning and clamping of the lamp housing from different positions, preventing the lamp housing from shifting or shaking due to vibration and inertia during movement, providing precise positioning for mechanical gripper to grasp, and avoiding grasping failure or damage.

[0021] This utility model, by setting a cable chain groove and a cable chain, provides a dedicated installation space and movement track for the cable chain.

[0032] 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.

[0033] Example 1:

[0034] Please see Figures 1 to 4 This utility model provides a technical solution:

[0035] A lamp housing feeding mechanism for a three-station glue station includes:

[0036] A machine frame 1 is provided, with a table 4 fixedly connected to its upper end surface, and a slide assembly 3 is provided above the table 4.

[0037] The slide assembly 3 includes two parallel guide rails 9 fixed on the table surface 4. A rodless cylinder 7 is arranged between the two guide rails 9. A lamp housing slide 6 is slidably connected above the guide rails 9 and the rodless cylinder 7. A lamp housing fixture 10 for positioning the lamp housing is provided on the upper end surface of the lamp housing slide 6. Drag chain grooves 5 are fixedly connected to both sides of the machine frame 1. A drag chain 501 is provided in the drag chain groove 5. One end of the drag chain 501 is fixedly connected to the front end of the lamp housing slide 6 through a connecting corner piece 502 and a bolt.

[0038] The cable chain groove 5 is fixed on both sides of the machine frame 1, providing dedicated installation space and movement track for the cable chain 501. It can effectively restrict the range of motion of the cable chain 501, prevent it from colliding or getting tangled with other components during equipment operation, and prevent external debris from entering the cable chain 501 and causing pollution or damage to the cables. This extends the service life of the cables, reduces downtime maintenance time caused by cable failures, and makes the internal wiring of the equipment neater and more orderly.

[0039] Specifically, a first slider 701 is slidably connected to the rodless cylinder 7, and connecting rods 702 are fixedly connected to both ends of the first slider 701. The connecting rods 702 are engaged with the grooves opened on the connecting block 703. The connecting block 703 is fixedly connected to the side of the first slider 701 by bolts, and the connecting block 703 is fixedly connected to the lamp housing slide 6 by bolts.

[0040] Specifically, the preferred rodless cylinder 7 is the MY3A50-600-A93Z model rodless cylinder 7. The rodless cylinder 7 does not require an exposed piston rod, has a compact structure, can effectively save the installation space between the two guide rails 9, avoid motion interference with the guide rails 9, lamp housing slide 6 and other components, and is compatible with the compact layout design of the feeding mechanism 12.

[0041] The rodless cylinder 7 transmits power directly through the first slider 701, and works in conjunction with the connecting rods 702 on both sides of the first slider 701 and the bolt-fixed connecting block 703. The upper end face of the connecting block 703 is fixedly connected to the lower end face of the lamp housing slide 6 (e.g., Figure 4 This enables the smooth linear motion of the lamp housing slide 6 with high motion accuracy, meeting the positional accuracy requirements during lamp housing feeding. The rodless cylinder 7 of this model has a fast response speed and stable output force, and can accurately control the moving speed and start / stop of the lamp housing slide 6.

[0042] Specifically, a second slider 901 is slidably connected to the guide rail 9, and the second slider 901 is fixedly connected to both sides of the lower end face of the lamp housing slide table 6 by bolts.

[0043] Specifically, the length of the guide rail 9 is greater than the length of the rodless cylinder 7, and the two guide rails 9 are symmetrically distributed about the axis of the rodless cylinder 7.

[0044] Guide rails 9 are installed on both sides of the rodless cylinder 7 on the table 4 to provide stable guidance and support for the lamp housing slide 6. The guide rails 9 slide in cooperation with the second sliders 901 on both sides of the lower end face of the lamp housing slide 6, which can accurately limit the movement trajectory of the lamp housing slide 6, ensuring that it always moves smoothly along a straight line, avoiding the deviation or shaking that may occur due to the rodless cylinder 7 driving alone, ensuring the positional accuracy during the lamp housing feeding process. In addition, the guide rails 9 can share the weight of the lamp housing slide 6 and the lamp housing, reduce the radial load borne by the rodless cylinder 7, reduce the risk of wear or failure caused by uneven force, and extend the service life of the equipment.

[0045] Specifically, the lamp housing fixture 10 includes a clamp 1002, which is fixedly connected to the upper end face of the lamp housing fixture 10. The lower end face of the lamp housing fixture 10 is fixedly connected to a fixing rod 1001, which is vertically fixed to the lamp housing slide table 6.

[0046] Multiple clamps 1002 (such as those provided on the lamp housing fixture 10) are installed on the lamp housing fixture 10. Figure 2The system can perform multi-point positioning and clamping of the lamp housing from different positions. When the lamp housing is placed on the fixture, each clamp 1002 is precisely matched with the outer contour of the lamp housing, thereby limiting the displacement of the lamp housing in the horizontal and vertical directions. This prevents the lamp housing from shifting or shaking due to vibration, inertia and other factors during the movement of the lamp housing slide 6, ensuring that the lamp housing remains stable. This provides precise positioning for the subsequent gripping action of the mechanical gripper 13, allowing the robot to accurately and smoothly grip the lamp housing according to the preset program, avoiding gripping failure or damage caused by lamp housing position deviation, and thus smoothly transferring the lamp housing to the next process.

[0047] Specifically, buffer limiting components 8 are provided on the front and rear ends of the slide assembly 3 on the platform 4. The buffer limiting components 8 include a buffer and a fixed seat. The buffer is fixed in the fixed seat, and the fixed seat is fixedly connected to the platform 4 by bolts.

[0048] The preferred buffer model is RBC2015S_MZ. Its principle is to use an internal hydraulic damping structure to slowly absorb kinetic energy when subjected to external impact by utilizing the viscous resistance of hydraulic oil. This converts the impact force generated by the movement of the lamp housing slide 6 into heat energy, which is gradually released, thus achieving a buffering process from high-speed movement to a smooth stop. When the lamp housing slide 6 moves to the front and rear limit positions under the drive of the rodless cylinder 7, it can accurately engage and buffer the impact force of the slide, avoiding rigid collisions between the slide and the table surface 4 or other components. Using a buffer can reduce the inertial impact of the slide movement, protect the guide rail 9, rodless cylinder 7, lamp housing fixture 10 and other components from damage, extend the service life of the equipment, and reduce the noise and vibration generated by collisions.

[0049] The buffer can also limit the movement of the lamp housing slide 6 to prevent it from overtraveling, providing a stable position for the mechanical gripper 13 to grab the lamp housing and enter the next process.

[0050] Specifically, an electrostatic gun assembly 11 is provided on one side of the tabletop 4. The electrostatic gun assembly 11 includes a fixing frame and an electrostatic gun. The fixing frame is vertically fixed on the tabletop 4, and the electrostatic gun is installed inside the fixing frame.

[0051] The preferred electrostatic gun is a Keyence series electrostatic gun (e.g., SJ-L005G). After the lamp housing is placed on the lamp housing fixture 10 and secured by the clamp 1002, the operator can hold the electrostatic gun and aim it at the surface of the lamp housing to perform an electrostatic removal operation. This electrostatic gun can neutralize the static electricity generated on the surface of the lamp housing due to friction and contact separation by releasing charges of opposite polarity, quickly eliminating the accumulation of static charge on the lamp housing. This prevents the lamp housing from attracting dust and impurities from the air due to static electricity, ensuring a clean surface and preventing problems such as poor adhesion, bubbles, or peeling of the adhesive layer due to impurities in the subsequent adhesive coating process. This ensures the quality of the adhesive coating and eliminates the potential risk of electric shock to operators caused by static electricity, while also avoiding safety hazards caused by static sparks, thus improving the safety of the operation process.

[0052] Specifically, a maintenance door 2 is provided at the front end of the machine frame 1. The maintenance door 2 is rotatably connected to the machine frame 1 via a hinge, and a handle 601 is provided on the maintenance door 2 to facilitate the staff to open the maintenance door 2 to repair the internal components.

[0053] Example 2:

[0054] Please see Figures 5 to 7 This utility model provides a technical solution:

[0055] like Figure 5 This is a three-station glue station equipped with the feeding mechanism 12 described in Example 1. When feeding is required, the rodless cylinder 7 drives the lamp housing slide 6 to slide outward to the preset feeding position. The operator can accurately place the lamp housing to be processed on the lamp housing fixture 10. The lamp housing is stably fixed by multi-point positioning of multiple clamps 1002. After confirming that the feeding is completed, the rodless cylinder 7 is activated, and the lamp housing slide 6 carries the lamp housing and slides inward along the guide rail 9. After touching the buffer limit component 8, the mechanical gripper 13 grabs the lamp housing. The top of the mechanical gripper 13 is equipped with a clamp that matches the shape of the lamp housing (such as...). Figure 7 The lamp housing is then transferred to the workstation of the turntable mechanism 14, which has three lamp housing workstations that can simultaneously carry multiple lamp housings into subsequent processes such as gluing.

[0056] In use, the rodless cylinder 7 drives the lamp housing slide 6 to slide outward to the preset loading position. During the process, the drag chain 501 moves with the slide to protect the cable. The worker places the lamp housing on the lamp housing fixture 10, fixes it with the clamp 1002, and then uses an electrostatic gun to remove static electricity from the lamp housing. After confirming that the loading is completed, the rodless cylinder 7 is started, and the lamp housing slide 6 slides inward along the guide rail 9. It stops in front of the mechanical gripper 13 after being limited by the buffer limit component 8. The mechanical gripper 13 can then grab the lamp housing and transfer it to the next process.

[0057] If maintenance is required, the maintenance door 2 can be opened via handle 601.

[0058] 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.

[0059] 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.
