Description

Technical Field

[0001] This utility model relates to testing equipment, and more particularly to a double-layer conveying mechanism and a resistance testing device. Background Technology

[0002] For example, many electronic products, such as electronic watches, require resistance testing of the metal casing and other components during the manufacturing process. Generally, the testing steps are as follows:

[0003] ① The conveyor belt delivers the workpiece carriers, and each workpiece carrier contains several workpieces to be tested;

[0004] ② The testing robot takes the workpiece to be tested out of the workpiece carrier and puts it into the resistance tester (during the test, the conveyor belt stops feeding to prevent the workpiece carrier from moving downstream and eventually completely leaving the working range of the testing robot).

[0005] ③ After the resistance testing machine performs resistance testing on the workpiece, the testing robot returns the workpiece to its original workpiece carrier.

[0006] ④ The conveyor belt delivers the workpiece carrier loaded with the tested workpiece to the downstream, and simultaneously moves another workpiece carrier loaded with the workpiece to be tested to the material handling position of the testing robot, so as to carry out the next round of testing.

[0007] During the resistance testing of a workpiece, in order to prevent the workpiece carrier corresponding to the workpiece being tested from being transported out of the working range of the testing robot and ultimately unable to be successfully placed back into the corresponding workpiece carrier, the conveyor belt will stop transporting the workpiece, which reduces the testing efficiency.

[0008] Especially when the conveyor belt needs to transport the workpiece to be tested for two, three or even more resistance testers, the problem of low testing efficiency is particularly obvious when the conveyor belt stops feeding.

[0009] Therefore, this utility model aims to improve existing conveyor belts to solve the problem of low inspection efficiency caused by their inability to perform transportation operations during workpiece inspection.

[0010] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0011] One objective of this invention is to provide a double-layer conveying mechanism and a resistance testing device, which can effectively solve the problem that existing conveyor belts cannot perform transportation operations during the workpiece inspection process, resulting in low inspection efficiency.

[0012] To achieve the above objectives, this utility model provides a double-layer conveying mechanism, comprising:

[0013] A lower-level conveying device, used for conveying workpiece carriers;

[0014] An upper buffer rack is located above the lower conveying device, and a gap space is left between the upper buffer rack and the lower conveying device for the workpiece carrier to pass through;

[0015] A buffer robot is located on the side of both the lower conveyor and the upper buffer rack, and is used to perform workpiece carrier transfer operations between the lower conveyor and the upper buffer rack.

[0016] Optionally, the lower conveying device includes two parallel conveyor belts spaced apart.

[0017] Optionally, a loading lifting mechanism located upstream of the upper buffer rack and a unloading lifting mechanism located downstream of the upper buffer rack are provided between the two conveyor belts.

[0018] On the other hand, a resistance detection device is provided, comprising:

[0019] Any of the aforementioned double-layer conveying mechanisms;

[0020] A pre-test positioning platform, wherein the pre-test positioning platform is provided with a pre-test positioning groove for positioning the workpiece to be tested;

[0021] A pre-test positioning robot is used to transfer the workpiece to be tested from the workpiece carrier on the lower conveying device to the pre-test positioning slot.

[0022] Several resistance testing machines are provided, wherein the resistance testing machines are used to receive the workpiece to be tested, perform resistance testing, and then send out the tested workpiece.

[0023] A delivery robot is used to transfer the workpiece to be tested in the pre-test positioning slot to each of the resistance testing machines.

[0024] Optional, also includes:

[0025] The post-test positioning platform is provided with a post-test positioning groove for positioning the tested workpiece; wherein, the test delivery robot is also used to transfer the tested workpiece from the resistance tester to the post-test positioning groove.

[0026] Optional, also includes:

[0027] A post-measurement positioning robot is used to transfer the measured workpiece in the post-measurement positioning slot to the workpiece carrier of the lower-level conveying device.

[0028] Optionally, both the pre-test positioning platform and the post-test positioning platform include a platform body and a platform linear drive mechanism that drives the platform body to move closer to or away from the test-delivery robot.

[0029] Optionally, it also includes a robot linear drive mechanism for driving the test-feeding robot to reciprocate linearly between each of the resistance testers.

[0030] The beneficial effects of this utility model are as follows: It provides a double-layer conveying mechanism and a resistance detection device. When resistance detection is required, the steps are as follows:

[0031] ①The lower conveyor delivers workpiece carriers, and each workpiece carrier contains several workpieces to be tested;

[0032] ②After the workpiece to be tested is removed from the workpiece carrier, the buffer robot removes the empty workpiece carrier from the lower conveyor and places it in the upper buffer rack to prevent the empty workpiece carrier from moving downstream continuously.

[0033] ③ After the resistance of the workpiece is detected, the buffer robot puts the corresponding workpiece carrier back into the lower conveyor so that the measured workpiece can be put back into the corresponding workpiece carrier in the future.

[0034] During the above process, the lower conveyor can continuously feed materials through the interval space, and the empty workpiece carrier will be buffered in the upper buffer rack. The feeding operation of the lower conveyor will not cause the empty workpiece carrier to continue to move downstream, and the situation where the tested workpiece cannot be put back into the corresponding workpiece carrier will not occur. Therefore, after the test is completed, the tested workpiece can be easily put back into the original workpiece carrier.

[0035] Therefore, the double-layer conveying mechanism and resistance detection equipment provided by this utility model can effectively solve the problem that existing conveyor belts cannot carry out transportation operations during the workpiece detection process, resulting in low detection efficiency.

[0061] The resistance detection device provided in this embodiment operates as follows:

[0062] (1) Workpiece loading: The workpiece to be tested is placed on the workpiece carrier of the lower conveyor device 101.

[0063] (2) Pre-measurement positioning:

[0064] a. The double-layer conveyor mechanism 1 delivers the workpiece carrier to the pre-measurement positioning robot 3.

[0065] b. The pre-test positioning robot 3 removes the workpiece to be tested from the workpiece carrier; the empty workpiece carrier is continuously conveyed to the buffer robot 103, which then moves it to the upper buffer rack 102.

[0066] c. The pre-test positioning robot 3 places the workpiece to be tested into the pre-test positioning slot of the pre-test positioning platform 2a.

[0067] (3) Resistance test:

[0068] a. The testing robot 5 removes the workpiece to be tested from the pre-test positioning slot.

[0069] b. The testing robot 5 transfers the workpiece to be tested to the corresponding resistance testing machine 4.

[0077] c. After measurement, the positioning robot 6 places the measured workpiece back into the workpiece carrier of the lower conveyor device 101.

[0078] (6) Workpiece output:

[0079] The lower conveyor 101 sends the workpiece carrier loaded with the measured workpiece out of the resistance testing equipment, completing the entire resistance testing process.

[0080] Furthermore, the double-layer conveying mechanism 1 provided in this embodiment, when a resistance detection operation is required, follows these steps:

[0081] ①The lower conveyor 101 delivers workpiece carriers, and each workpiece carrier contains several workpieces to be tested;

[0082] ② After the workpiece to be tested is removed from the workpiece carrier, the buffer robot 103 removes the empty workpiece carrier from the lower conveyor 101 and places it in the upper buffer rack 102 to prevent the empty workpiece carrier from moving downstream continuously.

[0083] ③ After the resistance of the workpiece is detected, the buffer robot 103 puts the corresponding workpiece carrier back into the lower conveyor 101 so that the measured workpiece can be put back into the corresponding workpiece carrier in the future.

[0084] During the above process, the lower conveyor 101 can continuously perform feeding operations through the interval space, and the empty workpiece carrier will be buffered in the upper buffer rack 102. The feeding operation of the lower conveyor 101 will not cause the empty workpiece carrier to continue to move downstream, and the situation where the tested workpiece cannot be put back into the corresponding workpiece carrier will not occur. Therefore, after the test is completed, the tested workpiece can be easily put back into the original workpiece carrier.

[0085] Therefore, the double-layer conveying mechanism 1 and resistance detection equipment provided by this utility model can effectively solve the problem that the existing conveyor belt 1011 cannot carry out transportation operations during the workpiece detection process, resulting in low detection efficiency.

[0086] In this embodiment, the lower conveying device 101 includes two parallel conveyor belts 1011 spaced apart. Between the two conveyor belts 1011, there is a loading lifting mechanism 1012 located upstream of the upper buffer rack 102 and a unloading lifting mechanism 1013 located downstream of the upper buffer rack 102.

[0087] Specifically, when the lower conveyor 101 moves the empty workpiece carrier to directly above the loading lifting mechanism 1012, the loading lifting mechanism 1012 rises upward, causing the workpiece carrier to detach from the two conveyor belts 1011. Then, the buffer robot 103 transfers the workpiece carrier from the loading lifting mechanism 1012 to the upper buffer rack 102.

[0088] Similarly, when it is necessary to send the workpiece carrier from the upper buffer rack 102 back to the conveyor belt 1011, the buffer robot 103 first moves the workpiece carrier to the material lifting mechanism, and then the unloading lifting mechanism 1013 moves downward to put the workpiece carrier back onto the conveyor belt 1011.

[0089] Optionally, both the pre-test positioning platform 2a and the post-test positioning platform 2b include a platform body 201 and a platform linear drive mechanism 202 that drives the platform body 201 to approach or move away from the delivery robot 5.

[0090] In this embodiment, the robotic arm linear drive mechanism 7 is used to drive the test delivery robotic arm 5 to reciprocate linearly between each of the resistance testers 4, so as to increase the working range of the test delivery robotic arm 5, thereby increasing the number of resistance testers 4 and further improving the detection efficiency.

[0091] It should be noted that the linear drive mechanism mentioned in this utility model can be a cylinder, hydraulic cylinder, electric cylinder, or motor lead screw linear module, etc., and the rotary drive mechanism mentioned can be a brushed motor, brushless motor, or rotary cylinder, etc. This utility model does not limit the specific structural form of the linear drive mechanism and the rotary drive mechanism.

[0092] In summary, the double-layer conveying mechanism 1 and the resistance detection device provided in this embodiment have the following advantages:

[0093] ① Improve detection efficiency: The design of the double-layer conveyor mechanism 1 allows the lower conveyor device 101 to continuously feed materials during the resistance detection process, while the upper buffer rack 102 is used to temporarily store empty workpiece carriers. This avoids the problem that the traditional conveyor belt 1011 cannot carry out transportation operations during the detection process, thereby significantly improving detection efficiency.

[0094] ② Precise workpiece recovery: The buffer robot 103 and the loading and unloading lifting mechanism 1013 ensure that the measured workpiece can be accurately returned to the original workpiece carrier, avoiding workpiece confusion and improving the accuracy of detection.

[0095] ③ Increased working range: The adoption of a robotic arm linear drive mechanism 7 enables the testing robotic arm 5 to reciprocate linearly between multiple resistance testing machines 4, increasing the working range and allowing for the configuration of more resistance testing machines 4, further improving testing efficiency.

[0096] ④ Space saving: The double-layer structure design effectively utilizes space, enabling the equipment to achieve more functions within a limited space.

[0097] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
