Description

Technical Field

[0001] This utility model relates to a reciprocating feeding mechanism, and more particularly to a reciprocating feeding mechanism for finished product assembly, belonging to the field of camera manufacturing technology. Background Technology

[0002] In the field of automated assembly of camera lens modules, disc conveyors are widely used because they can achieve continuous multi-station operation. Their matching reciprocating feeding mechanism needs to use pneumatic chucks to precisely clamp and assemble the tiny parts on the disc.

[0003] However, in actual production, it was found that when the pneumatic chuck on the gantry beam is driven by a lead screw to reciprocate, the total inertia of the moving parts is too large, which will cause significant inertial impact. On the one hand, the inertial force during acceleration / deceleration causes the ball screw on the gantry beam to bear additional load, which can easily cause deviation in the parallelism of the guide rail and increase the backlash of the lead screw, thereby reducing the positioning accuracy of the pneumatic chuck. On the other hand, the mechanical vibration caused by the inertial impact will be transmitted to the pneumatic chuck, causing the chuck to make a slight displacement at the moment of clamping, making it impossible to accurately align with the parts on the tray. In severe cases, the grippers may even scratch the parts or cause clamping failure.

[0004] To address this issue, a reciprocating feeding mechanism for finished product assembly was designed. Utility Model Content

[0005] The main purpose of this utility model is to provide a reciprocating feeding mechanism for finished product assembly, so as to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A reciprocating feeding mechanism for finished product assembly includes a gantry beam, mounting seats fixed at both ends of the gantry beam, a sliding plate that slides along the length of the gantry beam, a vertical cylinder that is vertically mounted on the top of the outer side of the sliding plate, and a pneumatic chuck mounted on the output end of the vertical cylinder.

[0008] Both ends of the top of the gantry beam are rotatably equipped with fixed pulleys, and a connecting rope is set between the two sets of fixed pulleys. The middle position of one side of the connecting rope is fixedly connected to the slide plate, and the middle position of the other side of the connecting rope is equipped with a counterweight component, which is slidably connected to the gantry beam.

[0009] Preferably, the top of the gantry beam is covered with a protective cover, and an openable cover plate is provided at the middle position of the top of the protective cover.

[0010] Preferably, the counterweight assembly includes a slider, a positioning post, a counterweight block, and a socket. The slider is slidably mounted on the top of the gantry beam. The positioning post is vertically fixed on the top of the slider. The counterweight block is parallel to the top of the slider and has a socket that mates with the positioning post.

[0011] Preferably, the counterweight assembly also includes a groove and a guide rail. The top of the gantry beam is fixed with a guide rail along its length, and the bottom of the slider has a groove that is engaged with the top of the guide rail.

[0012] Preferably, the vertical cylinder is detachably connected to the slide plate by bolts, and the pneumatic chuck is connected to the piston rod end of the vertical cylinder by a quick-release structure.

[0013] Preferably, at least two counterweights are provided, and multiple counterweights can be stacked and installed along the axial direction of the positioning column through the insertion hole. In two adjacent counterweights, the bottom of the upper counterweight fits with the top of the lower counterweight, and the top contour of the lower counterweight matches the bottom contour of the upper counterweight, so as to achieve stable stacking and counterweight adjustment of the counterweights.

[0014] Preferably, the outer circumferential surface of the fixed pulley is provided with an annular groove, and the connecting rope is embedded in the annular groove and slides in cooperation with the fixed pulley.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model constructs a dynamic balance system through the coordinated design of the counterweight component, fixed pulley, and connecting rope. When the slide plate on the gantry beam drives the pneumatic chuck to reciprocate, the connecting rope pulls the counterweight component to move synchronously in the opposite direction along the guide rail through the fixed pulley. The gravity of the counterweight block offsets part of the inertial force of the moving parts. This design directly reduces the total inertia of the moving parts, effectively weakens the inertial impact during acceleration / deceleration, thereby avoiding the ball screw bearing additional load, reducing mechanical wear problems such as guide rail parallelism deviation and increased screw backlash, significantly improving the service life of the core transmission components of the equipment, and reducing the frequency and cost of equipment maintenance. On the other hand, the improvement of overall motion stability avoids the slight displacement of the chuck due to vibration at the moment of clamping.

[0017] 2. This utility model adopts a modular and adjustable design for the counterweight component. Through the cooperation of the positioning post and the insertion hole, the number of counterweight blocks can be flexibly increased or decreased according to the weight of the parts to be assembled and the load changes of the pneumatic chuck. At the same time, the sliding cooperation between the slider and the guide rail, combined with the limiting effect of the groove on the positioning post, ensures that the counterweight blocks are installed stably and adjusted conveniently. This design allows the mechanism to be adapted to camera lens module parts of different specifications and weights without overall modification, which greatly improves the versatility of the equipment and reduces the cost for enterprises to change the feeding mechanism for different products.

[0030] Example 1

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a reciprocating feeding mechanism for finished product assembly, including a gantry beam 1, mounting seats 2 fixed at both ends of the gantry beam 1, a sliding plate 3 that slides along the length of the gantry beam 1, a vertical cylinder 4 vertically mounted on the top of the outer side of the sliding plate 3, and a pneumatic chuck 5 mounted on the output end of the vertical cylinder 4.

[0032] Fixed pulleys 6 are rotatably installed at both ends of the top of the gantry beam 1. A connecting rope 7 is provided between the two sets of fixed pulleys 6. The middle position of one side of the connecting rope 7 is fixedly connected to the slide plate 3. A counterweight component 8 is provided at the middle position of the other side of the connecting rope 7, and the counterweight component 8 is slidably connected to the gantry beam 1.

[0033] Before use, the gantry beam 1 is fixed to the designated workstation of the camera lens module assembly line using the mounting bracket 2 to ensure that the gantry beam 1 remains horizontal and stable. In the initial state, the slide plate 3 is stopped at the preset initial position along the length of the gantry beam 1, the vertical cylinder 4 is in the piston rod retracted state, driving the pneumatic chuck 5 to stay at a higher position to avoid interference with the lower tray or other components; the counterweight component 8 is stopped at the other end of the gantry beam 1 opposite to the slide plate 3 under the traction of the connecting rope 7. At this time, the connecting rope 7 is taut and close to the outer circumference of the fixed pulley 6, and the overall mechanism is in a ready-to-work balance state.

[0034] When the production line sends a feeding signal, the slide plate 3 slides along the length of the gantry beam 1 toward the part clamping station above the material tray. During this process, one end of the connecting rope 7, which is fixedly connected to the slide plate 3, moves synchronously with the slide plate 3. The connecting rope 7 changes the direction of force through the fixed pulleys 6 that are rotated at both ends of the gantry beam 1, pulling the counterweight assembly 8 at the other end of the connecting rope 7 to slide synchronously along the gantry beam 1 in the opposite direction to the slide plate 3.

[0035] When the slide plate 3 moves the vertical cylinder 4 and pneumatic chuck 5 directly above the part, the slide plate 3 stops sliding, and the counterweight assembly 8 also stops sliding in the opposite direction. At this time, the two are in dynamic balance through the connecting rope 7 and the fixed pulley 6. Then, the piston rod of the vertical cylinder 4 extends, driving the pneumatic chuck 5 to descend to the part clamping height. The pneumatic chuck 5 completes the precise clamping of the small part on the tray. After clamping, the piston rod of the vertical cylinder 4 retracts, driving the pneumatic chuck 5 holding the part to rise and reset. The slide plate 3 slides again along the gantry beam 1 towards the assembly station. At the same time, the counterweight assembly 8 continues to slide synchronously in the opposite direction. The gravity of the counterweight assembly 8 counteracts the total inertia of the moving parts composed of the slide plate 3, vertical cylinder 4, pneumatic chuck 5 and the part, greatly reducing the inertial impact generated during the acceleration and deceleration of the slide plate 3. This avoids the ball screw on the gantry beam 1 bearing additional load, reduces the problems of parallelism deviation and increased screw backlash, and ensures that the pneumatic chuck 5 is accurately positioned during movement.

[0036] When the slide plate 3 drives the pneumatic chuck 5 holding the part to the top of the assembly station, the slide plate 3 and the counterweight component 8 stop sliding synchronously, the piston rod of the vertical cylinder 4 extends again, and the part is transported to the designated position of the assembly mold. The pneumatic chuck 5 releases to complete the part assembly. After that, the piston rod of the vertical cylinder 4 retracts, the slide plate 3 returns to the initial position along the gantry beam 1, and the counterweight component 8 slides back to reset with the pull of the connecting rope 7. The mechanism returns to the initial standby state and waits for the next loading signal.

[0037] Example 2

[0038] The solution in Example 1 will be further described below with reference to its specific working method.

[0039] like Figure 2 and Figure 4 As shown, in a preferred embodiment, based on the above method, the top of the gantry beam 1 is further covered with a protective cover 9, and an openable cover plate 901 is provided at the middle position of the top of the protective cover 9.

[0040] The protective cover 9 covering the top of the gantry beam 1 completely encloses the fixed pulley 6, connecting rope 7, and counterweight assembly 8, preventing dust and oil from adhering to the surface of moving parts during production and affecting transmission accuracy. It also prevents operators from accidentally touching the moving counterweight assembly 8 or connecting rope 7, improving equipment operating safety. When maintenance of the counterweight assembly 8 is required, the openable cover 901 at the center of the top of the protective cover 9 can be opened without disassembling the entire protective cover 9, greatly simplifying the maintenance process.

[0041] like Figure 3As shown, in a preferred embodiment, based on the above method, the counterweight assembly 8 further includes a slider 801, a positioning post 802, a counterweight block 803, and a socket 804. The slider 801 is slidably disposed on the top of the gantry beam 1. The positioning post 802 is vertically fixed on the top of the slider 801. The counterweight block 803 is arranged parallel to the top of the slider 801. The counterweight block 803 is provided with a socket 804 that cooperates with the positioning post 802.

[0042] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, the counterweight assembly 8 further includes a groove 805 and a guide rail 806. The top of the gantry beam 1 is fixed with the guide rail 806 along the length direction, and the bottom of the slider 801 is provided with a groove 805, which is engaged with the top of the guide rail 806.

[0043] When the weight of the parts to be assembled changes, the counterweight can be adjusted by the cooperation of the positioning post 802 and the insertion hole 804: the counterweight block 803 is fitted onto the positioning post 802, which is vertically fixed on the top of the slider 801, through the insertion hole 804, so as to realize the quick installation of the counterweight block 803; if it is necessary to increase the counterweight, multiple counterweight blocks 803 can be stacked along the axial direction of the positioning post 802.

[0044] The guide rail 806 fixed along the length of the top of the gantry beam 1 and the groove 805 at the bottom of the slider 801 form a sliding pair. The groove 805 is stuck on the top of the guide rail 806, which restricts the slider 801 to slide only along the length of the guide rail 806, thus preventing the slider 801 from shifting laterally or wobbling during the sliding process.

[0045] like Figure 1 As shown, in a preferred embodiment, based on the above method, the vertical cylinder 4 is further detachably connected to the slide plate 3 by bolts, and the pneumatic chuck 5 is connected to the piston rod end of the vertical cylinder 4 by a quick-release structure.

[0046] When the vertical cylinder 4 malfunctions or the cylinder stroke needs to be adjusted according to the height of the part, the bolts can be directly removed to replace the vertical cylinder 4 with a suitable model. The pneumatic chuck 5 is connected to the piston rod end of the vertical cylinder 4 through a quick-release structure. When producing camera lens module parts of different specifications, it is necessary to replace the pneumatic chuck 5 with the corresponding size. There is no need to use complicated tools. The chuck can be replaced quickly through the quick-release structure.

[0047] like Figure 3As shown, in a preferred embodiment, based on the above method, at least two counterweights 803 are provided, and multiple counterweights 803 can be stacked and installed along the axial direction of the positioning post 802 through the insertion hole 804. In two adjacent counterweights 803, the bottom of the upper counterweight 803 fits with the top of the lower counterweight 803, and the top contour of the lower counterweight 803 matches the bottom contour of the upper counterweight 803, so as to achieve stable stacking and counterweight adjustment of the counterweights 803.

[0048] like Figure 1 As shown, in a preferred embodiment, based on the above method, the outer circumferential surface of the fixed pulley 6 is further provided with an annular groove, and the connecting rope 7 is embedded in the annular groove and slides with the fixed pulley 6 to prevent the connecting rope 7 from falling off the fixed pulley 6 during sliding, thus ensuring the traction stability of the connecting rope 7 on the slide plate 3 and the counterweight assembly 8.

[0049] Example 3

[0050] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0051] Overall installation and workstation adaptation: The gantry beam 1 is fixed to the corresponding workstation on the production line using the mounting base 2, ensuring the positioning accuracy of the mechanism and supporting equipment such as the disc conveyor. Initial adaptation and adjustment are completed according to the specifications of the camera lens module parts to be produced: If the parts have different weights, the weight of the counterweight assembly 8 is adjusted by stacking or removing the counterweight block 803 using the positioning column 802 and the insertion hole 804; if the parts have different dimensions or clamping requirements, the adaptable pneumatic chuck 5 is replaced using the quick-release structure, and the vertical cylinder 4 with the corresponding stroke is replaced by removing the bolts. Simultaneously, the protective cover 9 is closed, leaving only the cover plate 901 in the openable state, and the mechanism enters the ready-to-run state.

[0052] Full-process material loading and balancing operation: After the production line issues the material loading command, the slide plate 3 slides along the gantry beam 1 towards the material tray station. The connecting rope 7 pulls the counterweight component 8 to move in the opposite direction synchronously through the fixed pulley 6, forming dynamic balance. After the slide plate 3 is in place, the vertical cylinder 4 drives the pneumatic chuck 5 to descend and clamp the parts, then resets and moves towards the assembly station. The counterweight component 8 continues to slide in the opposite direction synchronously. Throughout the process, the gravity of the counterweight component 8 is used to counteract the inertia of the moving parts, avoiding positioning deviation and component wear caused by inertial impact. After reaching the assembly station, the pneumatic chuck 5 completes the assembly of the parts, and the slide plate 3 and the counterweight component 8 return to the initial position synchronously, completing one material loading cycle.

[0053] Long-term operation and maintenance guarantee: During continuous production, the protective cover 9 always protects the internal fixed pulley 6, connecting rope 7, and counterweight assembly 8 from external contamination, ensuring the accuracy of transmission components; when the vertical cylinder 4 and pneumatic chuck 5 are worn or malfunction, the components can be quickly replaced using the detachable connection and quick-release structure without long downtime; when the production line switches product specifications, the initial adaptation and adjustment steps are repeated, and the mechanism can be quickly changed by adding or removing counterweights 803 and replacing chucks and cylinders to adapt to the assembly requirements of different camera lens module parts, taking into account operational stability, positioning accuracy and production versatility.

[0054] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
