Description

Technical Field

[0001] This utility model mainly relates to the field of lens vibration testing technology, and specifically to a vibration testing machine. Background Technology

[0002] A lens is an optical component used in cameras, camcorders, and projectors to generate images. It can record and capture beautiful scenery and scenes in our lives, and can also be used as a security camera to guard homes, factories, streets, gardens, and other outdoor scenes.

[0003] Because optical lenses are precision instruments, they typically undergo a series of tests before leaving the factory, including airtightness testing, vibration testing, sorting and loading, MTF testing, and finally sorting and unloading. Currently, in the lens vibration testing process, existing vibration testing tables are used to detect lens vibration. During testing, workers need to place the lens under test on the vibration testing table and fix it in place before starting the test. After the test is completed, workers manually remove the lens and replace it with another lens to be tested. This manual loading and unloading method is cumbersome, involves frequent manual operations, can only test one lens at a time, requires a significant amount of time to complete the operation, and has significantly low work efficiency. Furthermore, each person can only be responsible for one machine and cannot manage multiple machines simultaneously, resulting in relatively high labor costs and overall inconvenience. Therefore, it is necessary to propose an improvement measure to solve the above-mentioned technical problems.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model:

[0006] This utility model provides a vibration testing machine to solve the technical problems existing in the background art.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, the technical solution provided by this utility model is: a vibration testing machine, including a working platform;

[0009] A feeding X-axis linear module is set on one side of the top of the workbench, and a loading plate is installed on the top of the movable seat of the feeding X-axis linear module.

[0010] A feeding X-axis linear module is set on the other side of the top of the workbench, and a feeding plate is installed on the top of the movable seat of the feeding X-axis linear module.

[0011] The vibration test bench is located at the top center of the workbench;

[0012] A three-axis moving mechanism is installed above the worktable;

[0013] The transfer and suction head module is mounted on a three-axis moving mechanism;

[0014] The feeding X-axis linear module delivers the loading plate to the bottom of the transfer and suction head module. The transfer and suction head module picks up the material tray on the loading plate and places it on the vibration test bench for vibration testing. After the test, the transfer and suction head module picks up the material tray on the vibration test bench and places it on the unloading plate of the feeding X-axis linear module. The feeding X-axis linear module then feeds the material.

[0015] Furthermore, the three-axis moving mechanism includes a material transfer X-axis linear module, a Y-axis linear module, and a Z-axis slide cylinder. The material transfer X-axis linear module is installed on the rear side of the top of the workbench. The Y-axis linear module is installed on the moving seat of the material transfer X-axis linear module. A mounting frame is installed on the moving seat of the Y-axis linear module. The Z-axis slide cylinder is installed on one side of the mounting frame. The transfer suction head module is installed on the bottom of the slide of the Z-axis slide cylinder.

[0016] Furthermore, a horizontally arranged linear slide rail is installed on the top front side of the workbench, and a slider is slidably installed on the linear slide rail. The bottom front side of the Y-axis linear module is installed on the slider of the linear slide rail.

[0017] Furthermore, the transfer and suction head module includes a bidirectional synchronous telescopic cylinder, which is installed at the bottom of the slide of the Z-axis slide cylinder. L-shaped connecting plates are installed on both sides of the telescopic rod end of the bidirectional synchronous telescopic cylinder. U-shaped clamping blocks are installed on both sides of the outer end of the L-shaped connecting plate. The bidirectional synchronous telescopic cylinder drives the L-shaped connecting plates on both sides to extend and retract, so that the lower part of the U-shaped clamping block is locked at the periphery of the material tray, realizing the picking and placing of the material tray.

[0018] Furthermore, on one side of the top of the workbench, there are two sets of parallel feeding X-axis linear modules, and the top of the moving seat of each of the two sets of feeding X-axis linear modules is equipped with a corresponding loading plate; on the other side of the top of the workbench, there are two sets of parallel feeding X-axis linear modules, and the top of the moving seat of each of the two sets of feeding X-axis linear modules is equipped with a corresponding unloading plate.

[0019] Furthermore, the top of the vibration test bench is provided with two material tray placement stations, and a first limiting stop is installed between the two material tray placement stations on the vibration test bench. A second limiting stop is installed on both sides of the two material tray placement stations on the vibration test bench. A clamping cylinder is installed on the outer side of each of the two material tray placement stations on the vibration test bench. A clamping block is installed on the telescopic rod end inside the clamping cylinder, and the material tray at the material tray placement station is clamped and fixed by the clamping block.

[0020] Furthermore, the material tray is provided with a plurality of material slots for placing lenses. The bottoms of the material slots are connected to each other. Air holes are provided on both sides of the material tray, and the air holes are connected to the bottoms of the material slots. When the clamping block presses and fixes the material tray at the placement station, the air hole on one side of the material tray is pressed and sealed by the first limiting strip. The air hole on one side of the material tray is connected to the negative pressure machine through a pipe, so that the lenses in the material slots of the material tray are adsorbed and fixed.

[0021] 3. Beneficial effects:

[0022] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0023] This utility model is rationally designed. It utilizes components such as a feeding X-axis linear module, a conveying X-axis linear module, a vibration testing platform, a three-axis moving mechanism, and a transfer and suction head module, all correspondingly arranged on the workbench. Multiple linear modules, telescopic cylinders, and the vibration testing platform work together. During operation, the feeding X-axis linear module delivers the loading plate to the underside of the transfer and suction head module. The transfer and suction head module, in conjunction with the three-axis moving mechanism, lifts the tray from the loading plate and places it on the vibration testing platform for vibration testing. After the test, the transfer and suction head module, again in conjunction with the three-axis moving mechanism, removes the vibrating plate from the platform. The material tray on the test bench is lifted and placed onto the unloading plate of the feeding X-axis linear module, which then feeds the material. The overall operation is simple, replacing manual loading and unloading and testing steps with a machine, reducing human intervention and achieving a high degree of automation. It can test the entire tray of lenses at once, effectively improving work efficiency and shortening the overall testing time. Its ingenious design and ease of use allow a single person to manage multiple devices simultaneously, greatly saving labor costs. Workers do not need to operate frequently, reducing labor intensity and making it highly practical.

[0034] See attached document Figures 1 to 3 A vibration testing machine according to this embodiment includes a worktable 1;

[0035] The feeding X-axis linear module 2 is set on one side of the top of the workbench 1. The top of the movable seat of the feeding X-axis linear module 2 is equipped with a loading plate 3. A material tray is placed on the loading plate 3, and multiple lenses to be tested are placed in the material tray.

[0036] A feeding X-axis linear module 9 is set on the other side of the top of the workbench 1. A feeding plate 10 is installed on the top of the movable seat of the feeding X-axis linear module 9. The feeding plate 10 is used to place the material tray that has been vibrated and tested.

[0037] Vibration test bench 8 is located at the top center of the workbench 1;

[0038] A three-axis moving mechanism is installed above the worktable 1;

[0039] The transfer suction head module 12 is mounted on the three-axis moving mechanism;

[0040] The feeding X-axis linear module 2 delivers the loading plate 3 to the underside of the transfer suction head module 12. The transfer suction head module 12 picks up the material tray on the loading plate 3 and places it on the vibration test table 8 for vibration testing. After the test is completed, the transfer suction head module 12 picks up the material tray on the vibration test table 8 and places it on the unloading plate 10 of the feeding X-axis linear module 9. The feeding X-axis linear module 9 then feeds the material.

[0041] Specifically, the three-axis moving mechanism includes a material transfer X-axis linear module 4, a Y-axis linear module 6, and a Z-axis slide cylinder 11. The material transfer X-axis linear module 4 is installed on the rear top of the worktable 1, and the bottom rear side of the Y-axis linear module 6 is installed on the moving seat of the material transfer X-axis linear module 4. A mounting frame 7 is installed on the moving seat of the Y-axis linear module 6, and the Z-axis slide cylinder 11 is installed on one side of the mounting frame 7. The transfer suction head module 12 is installed on the bottom of the slide of the Z-axis slide cylinder 11, and the transfer suction head module 12 can pick up the entire tray on the loading plate 3. A horizontally arranged linear slide rail 5 is installed on the front top of the worktable 1, and a slider is slidably installed on the linear slide rail 5. The bottom front side of the Y-axis linear module 6 is installed on the slider of the linear slide rail 5. By setting the linear slide rail 5, the stability and reliability of the movement of the Y-axis linear module 6 can be better guaranteed.

[0042] like Figure 3 As shown, the transfer and suction head module 12 includes a bidirectional synchronous telescopic cylinder 1201, which is installed at the bottom of the slide of the Z-axis slide cylinder 11. L-shaped connecting plates 1202 are installed on both sides of the telescopic rod end of the bidirectional synchronous telescopic cylinder 1201. U-shaped clamping blocks 1203 are installed on both sides of the outer end of the L-shaped connecting plate 1202. The bidirectional synchronous telescopic cylinder 1201 drives the L-shaped connecting plates 1202 on both sides to extend and retract, so that the lower part of the U-shaped clamping block 1203 can be locked at the periphery of the material tray, thereby realizing the picking and placing of the material tray.

[0043] Two sets of parallel feeding X-axis linear modules 2 are provided on one side of the top of the workbench 1, and a loading plate 3 is installed on the top of the moving base of each set of feeding X-axis linear modules 2. Two sets of parallel feeding X-axis linear modules 9 are provided on the other side of the top of the top of the workbench 1, and a unloading plate 10 is installed on the top of the moving base of each set of feeding X-axis linear modules 9. In this embodiment, by setting two sets of feeding X-axis linear modules 2 and two sets of feeding X-axis linear modules 9, it is possible to ensure that there are always untested material trays waiting to be tested on the loading plate 3 of the other set of feeding X-axis linear modules 2 during operation, thereby ensuring work efficiency.

[0044] The vibration test bench 8 has two tray placement stations 804 on its top. A first limiting strip 802 is installed between the two tray placement stations 804 on the vibration test bench 8. A second limiting strip 803 is installed on both sides of the two tray placement stations 804 on the vibration test bench 8. The tray placement station 804 is formed by the second limiting strips 803 on both sides and the first limiting strip 802 in the middle. The size of the tray placement station 804 is adapted to the size of the tray. A clamping cylinder 801 is installed on the outer side of each of the two tray placement stations 804 on the vibration test bench 8. A clamping block 805 is installed on the telescopic rod end inside the clamping cylinder 801. The tray at the tray placement station 804 is clamped and fixed by the clamping block 805. The tray has multiple slots for placing lenses, and the bottoms of the slots are connected to each other. Air holes are provided on both sides of the tray, and the air holes are connected to the bottoms of the slots. When the clamping block 805 presses and fixes the tray at the tray placement station 804, the air hole on one side of the tray is pressed and sealed by the first limiting strip 802. The air hole on one side of the tray is connected to a negative pressure machine or air pump through a pipe, so that the lenses in the tray slots are adsorbed and fixed, which facilitates the testing of the entire tray of lenses. Of course, in this embodiment, an air passage can also be provided within the clamping block 805. When the clamping block 805 clamps and fixes the material tray at the placement station 804, the air hole on one side of the material tray is sealed by the first limiting strip 802. The air hole on one side of the material tray is sealed and connected to the air passage on one side of the clamping block 805. The other side of the air passage of the clamping block 805 can be connected to a negative pressure machine or air pump through a pipe, which can also allow the lens in the material tray groove to be adsorbed and fixed. During operation, two material trays can be placed on the vibration test table 8 simultaneously for whole-tray testing, thereby effectively improving work efficiency.

[0045] It is worth noting that the worktable 1 has a box-like structure, and a closed box cover can be installed around the top of the worktable 1. Components such as the vibration testing platform 8, the three-axis moving mechanism, and the transfer and suction head module 12 on the top of the worktable 1 can be located inside the closed box cover. A flip-open box door can be installed on the side wall of the closed box cover to observe the internal working conditions and facilitate the loading and unloading of material trays by the operator. All linear modules, cylinders, vibration testing platforms 8, negative pressure machines, or air pumps used in this vibration testing machine can be directly adopted from existing equipment. The negative pressure machine or air pump can be installed on the lower inner side of the worktable 1. A control box can also be installed on the lower inner side of the worktable 1, containing a control system. All linear modules, cylinders, vibration testing platforms 8, negative pressure machines, or air pumps involved in this equipment are electrically connected to the control system to achieve automated control.

[0046] During operation, this vibration testing machine has a loading and unloading storage compartment installed on each side. Each loading and unloading compartment has two sets of storage spaces on the left and right sides, for vertically placing multiple horizontally sliding and pull-out trays. The trays in the loading compartment contain the material to be tested. Both the loading and unloading compartments can be raised and lowered via Z-axis linear modules. The loading plate 3 of the feeding X-axis linear module 2 can extend between adjacent trays in the loading compartment, and the trays are pulled out in conjunction with the lifting of the loading compartment to achieve loading. The unloading plate 10 of the feeding X-axis linear module 9 can extend between adjacent trays in the unloading compartment, and the trays are inserted in conjunction with the lifting of the unloading compartment to achieve unloading. Of course, considering the automation of the overall lens testing process, this vibration testing machine can also be equipped with an airtightness testing machine and a sorting machine on its two sides respectively. The airtightness testing machine is located on one side of the feeding X-axis linear module 2 of the vibration testing machine, and the sorting machine is located on one side of the feeding X-axis linear module 9 of the vibration testing machine. A portion of the feeding X-axis linear module 2 is installed on one side of the working platform 1 of the vibration testing machine, and the other portion is installed on the top of the platform of the airtightness testing machine, used to feed the lenses that have completed the airtightness test into the vibration testing machine for testing. A portion of the feeding X-axis linear module 9 is installed on the other side of the working platform 1 of the vibration testing machine, and the other portion is installed on the top of the platform of the sorting machine, used to feed the lenses that have completed the vibration test into the sorting machine for sorting.

[0047] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
