[0046] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation to the present application. It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0047] Please refer toFigures 1 - 13 The present application provides a testing device, including a testing box 10, a first carrying platform 20, a first feeding mechanism 30, a testing chamber 40, and an electronic device 50. Specifically, the first feeding mechanism 30 is disposed between the first carrying platform 20 and the testing chamber 40, and the testing box 10 moves among the first carrying platform 20, the first feeding mechanism 30, and the testing chamber 40. The electronic device 50 can be installed at any position of the testing device, preferably near the testing chamber 40.

[0048] Please refer to Figure 2 and Figure 5 , the testing box 10 includes testing contacts 11 and at least one workpiece testing position 12 for loading a workpiece 01. When the testing box 10 moves on the first carrying platform 20, it is movably disposed on a second bracket 22 of the first carrying platform 20.

[0049] In an embodiment, the testing box 10 further includes a pressing assembly. A second ejector pin 14 matching the workpiece 01 is disposed on the workpiece testing position 12 (optionally, the second ejector pin 14 is electrically connected to the testing contacts 11). When the workpiece 01 is placed in the workpiece testing position 12, the contacts on the workpiece 01 come into contact with the second ejector pin 14. The pressing assembly is used to fix the workpiece 01 on the testing box 10 to ensure that the workpiece 01 remains in contact with the second ejector pin 14. Optionally, the pressing assembly includes a pressing plate 13 and a spring (not shown). The pressing plate 13 is disposed on the upper surface of the testing box 10, and the spring drives the pressing plate 13 to press the workpiece 01 onto the testing box 10. A connecting rod (not shown in the figure) is disposed on the lower surface of the pressing plate 13. A through hole for the connecting rod to pass through is formed on the testing box 10. The connecting rod passes through the through hole and extends below the testing box 10. A jacking assembly (not shown) is disposed below the testing box 10. The jacking assembly includes a jacking driving member and a jacking block. The body of the jacking driving member is disposed on the first carrying platform 20 or the second bracket 22, and the jacking block is disposed at the output end of the jacking driving member. After the jacking driving member drives the jacking block to move upward, the connecting rod is pushed, so that the pressing plate 13 separates from the upper surface of the testing box 10 against the action of the spring, thereby releasing the workpiece 01 on the testing box 10. In some embodiments, a limiting post (not shown) is connected to the lower surface of the jacking block, and a limiting sleeve (not shown) matching the limiting post is disposed on the first carrying platform 20 or the second bracket 22 to limit the movement of the jacking block in the vertical direction.

[0050] The test box 10 is used to accommodate multiple workpieces 01 for further batch testing. When the test box 10 is waiting for the workpiece, the clamping assembly is first released, and the robot arm transfers the workpiece 01 to the workpiece test position 12 in the test box 10. When the workpiece test position 12 of the test box 10 is full of workpieces 01, or the loading work reaches the target amount, the clamping assembly clamps all the workpieces 01 on the test box 10. The workpiece 01 contacts the second ejector pin 14 in the workpiece test position 12 of the test box 10, and all the second ejector pins 14 in the test box 10 are signal-connected with the test module in the test box 10, which is used to perform further batch testing on all the workpieces 01 in the test box 10, such as aging testing (trial running of the workpiece 01, such as running for a preset time period to test whether the performance of the workpiece 01 is stable). After the clamping assembly clamps all the workpieces 01 onto the test box 10, the test box 10 is sent to the test room 40 for batch testing.

[0051] The first feeding mechanism 30 is used to transfer the test box 10 loaded with at least one workpiece 01 from the first carrying platform 20 to the feed port 41 of the test room 40 , and is disposed between the first carrying platform 10 and the feed port 41 of the test room 40 .

[0052] In one embodiment, please refer to Figures 6 - 9 The first feeding mechanism 30 includes a feeding belt unit 32 and a ratchet conveying unit 39 .

[0053] The feeding belt unit 32 includes a feeding belt 321 , a feeding wheel set 322 and a first driving member 37 . The feeding belt 321 is sleeved on the periphery of the feeding wheel set 322 , and a power output end of the first driving member 37 is drivingly connected to the feeding wheel set 322 .

[0054] The ratchet conveying unit 39 includes a ratchet 394 and a second driving member 391. The ratchet 394 is arranged at the power output end of the second driving member 391. The ratchet 394 is used to extend out of the range of the feeding belt 321 in the opposite direction of the feeding direction of the feeding belt 321 under the drive of the second driving member 391 and buckle the test box 10 to be conveyed, and move along the feeding direction of the feeding belt 321 under the drive of the second driving member 391 to move the test box 10 onto the feeding belt 321.

[0055] Optionally, when the pawl 394 is subjected to a force in the feeding direction of the feeding belt 321, the pawl 394 retracts, and when the pawl 394 is subjected to a force in the opposite direction of the feeding direction of the feeding belt 321, the pawl 394 does not retract. That is, when the pawl 394 moves in the opposite direction of the feeding direction of the feeding belt 321 under the drive of the second driving member 391, the pawl 394 approaches the test cartridge 10 from far to near and abuts against the bottom of the test cartridge 10. When the pawl 394 further moves in the opposite direction of the feeding direction of the feeding belt 321 under the drive of the second driving member 391, at this time, the pawl 394 is subjected to the pressure in the feeding direction of the feeding belt 321 applied by the test cartridge 10, and the pawl 394 retracts to let the test cartridge 10 pass. When the pawl 394 moves to the designed buckling position, the pawl 394 is no longer subjected to the pressure in the feeding direction of the feeding belt 321 applied by the test cartridge 10, and the pawl 394 pops up and buckles the test cartridge 10. At this time, the pawl 394 moves in the feeding direction of the feeding belt 321 under the two-stage drive (cylinder retraction) of the second driving member 391, so as to move the test cartridge 10 onto the feeding belt 321. Then, the first driving member 37 drives the feed wheel set 322 to rotate, and the rotation of the feed wheel set 322 drives the feeding belt 321 to move the test cartridge 10 to the target position (such as the feeding port 41 of the test chamber 40).

[0056] In the test device of the present application, the first feeding mechanism 30 is designed to include a feeding belt unit 32 and a pawl conveying unit 39. The first driving member 37 of the feeding belt unit 32 outputs power to the feed wheel set 322, and the feed wheel set 322 drives the feeding belt 321 to rotate for feeding. The second driving member 391 in the pawl conveying unit 39 can drive the pawl 394 to move in the opposite direction of the feeding direction of the feeding belt 321, and buckle the test cartridge 10 outside the feeding range of the feeding belt 321. Then, the pawl 394 moves in the feeding direction of the feeding belt 321 under the drive of the second driving member 391, so as to move the test cartridge 10 onto the feeding belt 321, realizing the function of automatically uploading the material to the conveyor belt 11, reducing the input of labor costs and improving the efficiency.

[0057] In some alternative embodiments, the feeding device further includes a base 31. The base 31 includes a height-adjustable table body 311 and a table top 312 provided on the table body 311. Both the feeding belt unit 32 and the pawl conveying unit 39 are provided on the table top 312.

[0058] During implementation, the height of the pedestal body 311 in the base 31 is adjustable. For example, the pedestal body 311 is designed to include a pedestal column and a side wall. Among them, the pedestal column is composed of multiple sections of hollow cylinders, and the height of the pedestal body 311 is adjustable by adjusting the number of hollow cylinders. Or multiple bosses are provided in the vertical direction of the pedestal body 311, and the tabletop 312 can be snap-connected to the bosses, so as to realize the function of adjusting the height of the tabletop 312. The feeding belt unit 32 and the ratchet conveying unit 39 are both arranged on the tabletop 312, and thus the heights of the feeding belt unit 32 and the ratchet conveying unit 39 can be adjusted. In some embodiments, the base 31 further includes universal wheels arranged at the bottom of the pedestal body 311, which facilitates the movement of the base 31.

[0059] In some alternative embodiments, the feeding belt unit 32 further includes a tape base frame 33. The tape base frame 33 includes a tape frame 34 and several tape columns 35.

[0060] Optionally, the feeding belt unit 32 includes a first tape base frame and a second tape base frame which are symmetrically arranged. The feeding wheel sets 322 of the first tape base frame and the feeding wheel sets 322 of the second tape base frame are connected by a transmission shaft 36, and the power output end of the first driving member 37 is connected to the transmission shaft 36. Specifically, the tape frame 34 is installed and fixed on the tabletop 312 through multiple tape columns 35. Feeding wheel sets 322 are arranged at both ends of the tape frame 34, and the feeding belt 321 is sleeved around the tape frame 34. The feeding wheel sets 322 are connected to the power output end of the first driving member 37 through the transmission shaft 36. The first driving member 37 drives the feeding wheel sets 322 on the first tape base frame and the second tape base frame to rotate synchronously, so as to realize the synchronous rotation of the feeding belts 321 on the first tape base frame and the second tape base frame.

[0061] In some alternative embodiments, the ratchet conveying unit 39 includes a first guide rail 395 and a first slider 392. The first guide rail 395 is arranged on the tabletop 312, the first slider 392 is arranged on the first guide rail 395 and can slide along the first guide rail 395, the ratchet 394 is arranged on the first slider 392, and the power output end of the second driving member 391 is connected to the first slider 392.

[0062] During implementation, the first guide rail 395 is arranged on the tabletop 312 in parallel with the opposite direction of the feeding direction of the feeding belt 321. The first slider 392 can slide along the first guide rail 395. When the first slider 392 slides along the first guide rail 395 driven by the second driving member 391, the first slider 392 drives the ratchet 394 to slide along the first guide rail 395, avoiding the situation that the ratchet 394 moves and deviates, thereby improving the stroke stability of the ratchet 394.

[0063] In some alternative embodiments, the pawl conveying unit 39 further includes a pawl adjusting rod 393 and an adjusting bolt. The pawl 394 is connected to one end of the pawl adjusting rod 393. The pawl adjusting rod 393 is provided with a plurality of adjusting holes, and one end of the adjusting bolt passes through the adjusting hole and is connected to the first slider 392. By setting the position between the pawl adjusting rod 393 and the first slider 392 to be adjustable, the moving range of the pawl 394 can be adjusted, so as to be applicable to test boxes 10 of different sizes, with strong practicability.

The gripper track 462 in the conveying mechanism 46 is laid inside the housing 42, and the feeding gripper 461 is installed on the gripper track 462 and can slide on the gripper track 462, enabling the feeding gripper 461 to pick up the test box 10 and transport it to the test station 441 for testing, or to remove the tested test box 10 from the test station 441 and transport it out. There is no need for staff to enter and exit the housing 42 to pick up and place workpieces, reducing the investment in labor costs and having a high test efficiency. Thirdly, a ventilation duct 45 is provided at the top of the housing 42, which can extract the high-temperature air generated during the test process and cool the inside of the housing 42 at the same time, avoiding damage to the device and equipment caused by high temperature and increasing the service life of the test chamber 40.

[0073] In some alternative embodiments, the storage cabinet 44 includes at least one test station layer. The test station layer includes a plurality of test stations 441, and a feed track is provided on the test station layer. Optionally, the test stations 441 are arranged in layers, and each test station layer includes a plurality of test stations 441. The test box 10 is provided with a track groove corresponding to the feed track, and the feed track and the track groove are used in cooperation to enable the test box 10 to be accurately docked with the test connector. In some embodiments, in order to facilitate the contact between the test contacts of the test box 10 and the test connector, the test station 441 can be designed to be high at one end and low at the other end, and the test connector in the test station 441 is arranged at the low end. When the manipulator picks up the test box 10 and places it on the feed track, the test box 10 slides down under the action of gravity and is docked with the test connector for testing.

[0074] In some alternative embodiments, an observation window 412 and a rear cover 49 are provided at the corresponding position of the side wall 48 and the storage cabinet 44. The rear cover 49 covers the observation window 412, and a sealing strip is provided at the edge of the rear cover 49 facing the observation window 412. By providing the observation window 412 and the rear cover 49 on the side wall 48, the rear cover 49 can move relative to the side wall 48. For example, the rear cover 49 is hinged or slidably connected to the side wall 48. Opening the rear cover 49 can see the inside of the housing 42 through the observation window 412 and observe the situation of each test station 441 in the storage cabinet 44.

[0075] In some alternative embodiments, a number of heat dissipation air outlets 411 are provided at positions corresponding to the test station layer on the rear cover 49, and fans are provided at the heat dissipation air outlets 411. The heat dissipation air outlets 411 are arranged corresponding to the test station layer, that is, each layer of the test station layer corresponds to a heat dissipation air outlet 411 provided on the rear cover 49, and each heat dissipation air outlet 411 is provided with a fan. The fan blows air into the test station layer, thereby dissipating heat from the test station layer.

[0076] In an alternative embodiment, the housing 42 includes a first feeding channel and a second feeding channel which are symmetrically arranged. The first feeding channel includes a first feeding channel bracket and a number of first feeding rollers provided on the first feeding channel bracket. An inlet 41 is provided at the position where the side wall 48 is connected to the first feeding channel. The second feeding channel includes a second feeding channel bracket and a number of second feeding rollers provided on the second feeding channel bracket. Another inlet 41 is provided at the position where the side wall 48 is connected to the second feeding channel.

[0077] In an embodiment, the housing 42 includes a first discharging channel and a second discharging channel which are symmetrically arranged. The first discharging channel includes a first discharging channel bracket and a number of first discharging rollers provided on the first discharging channel bracket. An outlet 47 is provided at the position where the side wall 48 is connected to the first discharging channel. The second discharging channel includes a second discharging channel bracket and a number of second discharging rollers provided on the second discharging channel bracket. Another outlet 47 is provided at the position where the side wall 48 is connected to the second discharging channel. During implementation, a feeding channel and a discharging channel are respectively provided on both sides of the housing 42, thereby improving the test efficiency. That is, as Figure 1 shown, inlets 41 and outlets 42 for the test cartridges 10 to enter and exit can be provided at both ends or all four ends (which can be understood as each end of the test chamber 40) of the test chamber 40.

[0078] An electronic device 50 is configured to receive the operation information of the workpiece 01. If the operation information includes an error message, the workpiece 01 located at the workpiece test position 12 corresponding to the error message is determined as the failed workpiece 01.

[0079] In an embodiment, the electronic device 50 can be a numerical control device, a mobile terminal, a PC (personal computer), a mobile phone, etc., a device having a display, a processor, a memory, and a signal transceiver. The signals during the test of the workpiece 01 in the test chamber 40 will be transmitted to the electronic device 50 at a preset frequency. The electronic device 50 has functions such as parsing data and sending warning messages.

[0080] In one embodiment, the test device further includes a second bearing platform 60 and a second feeding mechanism 70. The second feeding mechanism 70 is connected to the discharge port 47 of the test room 40, and is used to take out the test box 10 that has completed the test from the discharge port of the test room 40; specifically, compared with the first feeding mechanism 30, the second feeding mechanism 70 has different feeding directions, such as the feeding direction of the first feeding mechanism 30 is from the first bearing platform 20 to the test room 40, and the feeding direction of the second feeding mechanism 70 is from the test room 40 to the second bearing platform 60 (the feeding directions of the two are opposite), and the other related components and operation modes of the two are the same, and the components and operation modes included in the second feeding mechanism 70 are not described here. The second carrying platform 60 is arranged at the tail end of the feeding direction of the second feeding mechanism 70, and is used to carry the test box 10 that has completed the test. Specifically, the second feeding mechanism 70 transfers the test box 10 from the discharge port 47 of the test room 40 to the second bracket 22 of the second carrying platform 60, and the test box 10 is movable on the second bracket 22.

[0081] In one embodiment, please refer to Figures 2 - 4 The test equipment includes a first functional testing mechanism 80 for performing functional testing on a workpiece; specifically, the first functional testing mechanism 80 is disposed on the first bracket 21 of the first carrying platform 20. The first functional testing mechanism 80 includes a transmission component and a test component. The transmission component includes a conveyor belt 81 and a workpiece fixture 82 mounted on the conveyor belt 81, and the workpiece fixture 82 is used to load the workpiece 01; the test component includes a test drive 84 and a first ejector pin 83. The body of the test drive 84 is fixedly connected to the first bracket 21 on the first carrying platform 20, and the first ejector pin 83 is transmission-connected to the test drive 84, and is used to drive the first ejector pin 83 to contact the workpiece 01 in the workpiece fixture 82. Among them, the first bracket 21 is disposed at one end of the second bracket 22 away from the first feeding mechanism 30.

[0082] When the first function testing mechanism 80 is used to perform function testing on the workpiece 01, the workpiece 01 is placed on the workpiece fixture 82 at the initial position of the conveyor belt 81. The conveyor belt 81 transports the workpiece fixture 82 to the test position, that is, the position corresponding to the test component. The test driving member 84 drives the first ejector pin 83 to drop, so that the first ejector pin 83 contacts the contact point on the workpiece 01 for testing. The content of the function testing can be adjusted according to the actual application scenario, including but not limited to input / output current, input / output voltage, etc. In some embodiments, multiple test components are provided on the first function testing mechanism 80, which can respectively test different parameters of the workpiece 01 or test multiple workpieces 01 simultaneously. For example, three test components are set to sequentially test the current, power, and resistance of the workpiece 01, or test the resistance of three workpieces 01 simultaneously. After being tested by the test component, the conveyor belt 81 transports the workpiece fixture 82 to the end of the conveyor belt 81, and the qualified workpiece 01 is transferred to the workpiece test position 12 of the test box 10 without loaded workpieces by the robotic arm. The workpiece fixture 82 is transported back to the initial position of the conveyor belt 81 to wait for the next batch of workpieces 01.

[0083] In the above embodiment, the conveyor belt 81 is used to transport the workpiece 01, and the test component is used to perform function testing on the workpiece 01, which can realize the automation of the workpiece 01 testing. Multiple test components can be set to perform multi-dimensional testing on the workpiece 01 or test multiple workpieces 01 simultaneously. Integrating multiple test items onto the same mechanism reduces the space occupied by the function testing mechanism. The workpiece 01 after being tested by the test component is transferred to the test box 10 for batch testing, further improving the testing efficiency.

[0084] In some embodiments, please refer to Figure 3, the first function testing mechanism 30 further includes a positioning component, which is arranged in a supporting manner with the testing component. The positioning component is symmetrically arranged at a position below the first function testing mechanism 30 and close to the conveyor belt 81, and includes a positioning block 87 and a positioning driving member 88. The body of the positioning driving member 88 is connected to the first bracket 21, and the positioning block 87 is arranged at the output end of the positioning driving member 88. A matching first convex block 86 and a first groove 85 are arranged on the positioning block 87 and the workpiece fixture 82. When the workpiece fixture 82 is transported to the testing position through the conveyor belt 81, the positioning driving member 88 drives the positioning block 87 to clamp the workpiece fixture 82. At this time, the first convex block 86 and the first groove 85 are matched to fix the workpiece fixture 82 at the testing position below the first thimble 83, ensuring that the first thimble 83 can contact the contact point of the workpiece 01 when it falls, so as to conduct the test. In some embodiments, chamfers are arranged on the first convex block 86 and the first groove 85, which can correct the position of the workpiece fixture 82 within a certain limit when the positioning block 87 clamps the workpiece fixture 82, ensuring that the first convex block 86 and the first groove 85 can be smoothly matched, and further improving the positioning efficiency of the workpiece fixture 82.

[0085] Please refer to Figure 4 , Figure 4 For Figure 2 an enlarged schematic view of part B in. As shown in the figure, in some embodiments, the conveyor belt 81 includes two sets of sub-conveyor belts with opposite moving directions. In this embodiment, it is assumed that the sub-conveyor belt for transporting the workpiece 01 for function testing is the first sub-conveyor belt 811, and the other sub-conveyor belt is the second sub-conveyor belt 812. When the workpiece fixture 82 is transported to the end of the first sub-conveyor belt 811, after the mechanical arm takes away the workpiece 01, the empty workpiece fixture 82 is transferred to the initial end of the second sub-conveyor belt 812, and then the empty workpiece fixture 82 is transported by the second sub-conveyor belt 812 to a position near (below) the initial end of the first sub-conveyor belt 811, and then the empty workpiece fixture 82 is transferred from the second sub-conveyor belt 812 to the initial end of the first sub-conveyor belt 811 to wait for the next workpiece 01. By setting two sets of sub-conveyor belts with opposite directions, the recycling of the workpiece fixture 82 is realized, making the back-and-forth transportation of the workpiece fixture 82 more convenient.

[0086] In some embodiments, two sub-conveyor belts are arranged in parallel up and down, the second sub-conveyor belt 812 is arranged below the first sub-conveyor belt 811, and the first functional test mechanism 30 further includes two sets of transfer components arranged at the head and tail ends of the conveyor belt 81 for transferring the workpiece fixture 82 between the two sub-conveyor belts. Specifically, the transfer component includes a first cylinder 91, a second cylinder 94 and a connecting member 92. In this embodiment, the first cylinder 91 is a translation cylinder and the second cylinder 94 is a rotary cylinder. The first cylinder 91 is vertically arranged below the conveyor belt 81, the second cylinder 94 is arranged at the output end of the first cylinder 91, and the connecting member 92 is arranged at the output end of the second cylinder 94, so that the first cylinder 91 can drive the second cylinder 94 and the connecting member 92 to move in the vertical direction, and the second cylinder 94 can drive the connecting member 92 to rotate on the horizontal plane.

[0087] When transferring the workpiece fixture 82, the first sub-conveyor belt 811 transports the workpiece fixture 82 above the transfer component. The first cylinder 91 pushes the second cylinder 94 and the connecting member 92 to move vertically upward. The connecting member 92 contacts the workpiece fixture 82, and the first cylinder 91 continues to push upward to separate the workpiece fixture 82 from the first sub-conveyor belt 811. Then the second cylinder 94 drives the connecting member 92 and the workpiece fixture 82 to rotate a preset angle so that the workpiece fixture 82 can avoid the conveyor belt 81. The output end of the first cylinder 91 descends, driving the workpiece fixture 82 to descend to a position lower than the first sub-conveyor belt 811 and higher than the second sub-conveyor belt 812. The second cylinder 94 rotates back, and the workpiece fixture 82 returns to the original angle. The first cylinder 91 continues to descend, and the workpiece fixture 82 is placed on the second sub-conveyor belt 812 and separated from the connecting member 92. The second sub-conveyor belt 812 transports the workpiece fixture 82 above the transfer component at the other end of the conveyor belt 81. The first cylinder 91 of the other set of transfer components jacks up, so that the connecting member 92 contacts and jacks up the workpiece fixture 82. The workpiece fixture 82 is separated from the second sub-conveyor belt 812. The second cylinder 94 rotates a preset angle to make the workpiece fixture 82 avoid the conveyor belt 81. The first cylinder 91 continues to rise, jacking up the workpiece fixture 82 to a position higher than the first sub-conveyor belt 812. The second cylinder 94 rotates back to make the workpiece fixture 82 return to the original angle. The first cylinder 91 descends, and the workpiece fixture 82 is placed on the first sub-conveyor belt 812 and separated from the connecting member 92, completing the transfer of the workpiece fixture 82.

[0088] In some embodiments, the bottom of the connecting member 92 and the workpiece fixture 82 are provided with a second convex block 93 and a second groove (not shown) that are adapted to each other. When the connecting member 92 jacks up the workpiece fixture 82, the second convex block 93 and the second groove match to limit the workpiece fixture 82. In some embodiments, the second convex block 93 is a magnet, and both the workpiece fixture 82 and the connecting member 92 can be made of a metal material that can be adsorbed by the magnet, making the connection between the workpiece fixture 82 and the connecting member 92 more stable during the transfer process.

[0089] In an embodiment of the present application, the first function testing mechanism 80 is used to perform a function test on the workpiece 01 before the workpiece 01 enters the test chamber 40 for testing. If the function test fails, the workpiece will no longer be conveyed into the test chamber 40 for testing, so as to improve the test efficiency of the test chamber 40.

[0090] In an embodiment, the test equipment further includes a second function testing mechanism 90. The second function testing mechanism 90 is arranged on the first bracket 21 of the second bearing platform and is used to perform a function test on the workpiece 01 after the workpiece 01 enters the test chamber 40 and completes the test, so as to improve the qualified rate of the workpiece 01 put into the market. Specifically, the first bracket 21 is at the end of the second bracket 22 away from the second feeding mechanism 70.

[0091] Optionally, when the test equipment includes the first function testing mechanism 80 and the second function testing mechanism 90, the test of the workpiece 01 by the first function testing mechanism 80 can be understood as a preliminary test, and the test of the workpiece 01 by the second function testing mechanism 90 can be understood as a retest. The function tests of the two on the workpiece 01 can be the same or different, and can be adjusted according to the actual situation (for example, both test the resistance performance of the workpiece 01, or one tests the voltage performance of the workpiece 01 and the other tests the current performance of the workpiece 01). In an embodiment, the relevant components and operating modes included in the first function testing mechanism 80 and the second function testing mechanism 90 are the same, and the second function testing mechanism 90 will not be described in detail here.

[0092] In an embodiment, please refer to Figure 2 The test equipment further includes a detection mechanism 110. The detection mechanism 110 is arranged on the first bearing platform 20 and is adjacent to the second bracket 22, and is used to detect whether the test box 10 and each workpiece test position 12 on the test box 10 are operating normally. Specifically, the detection mechanism 110 is provided with a third ejector pin 111 that cooperates with the test contact 11 on the test box 10. The test box 10 is tested before the workpiece 01 is placed on the test box 10 to determine whether the test box 10 and each workpiece test position 12 on the test box 10 can work normally. When some workpiece test positions 12 on the test box 10 cannot work normally, information is fed back to the control center, and the robotic arm is controlled not to place the workpiece 01 in the non-operating workpiece test positions 12.

[0093] In one embodiment, a positioning assembly (not shown) is provided at one end of the second bracket 22 away from the detection mechanism 110. The positioning assembly includes a positioning post rotatable in a vertical plane and a rotation driving member for driving the positioning post to rotate. When the positioning post is in a non-operating state, it is in a horizontal state. When the test box 10 needs to load or test the workpiece 01, the rotation driving member drives the positioning post to rotate from the horizontal state to the vertical state. The positioning post contacts the surface of the test box 10 away from the third thimble 111 to ensure the contact between the test box 10 and the third thimble 111, and prevent the test box 10 from detaching from the third thimble 111, thus realizing the positioning of the test box 10. In some embodiments, the positioning post can move in the horizontal direction. The positioning assembly further includes a moving driving member. When the positioning post rotates to the vertical state, the moving driving member drives the positioning post and the rotation driving member to move together towards the third thimble 111, so as to use the positioning post to urge the test box 10 to press against the third thimble 111, further ensuring the contact between the test box 10 and the third thimble 111, and at the same time ensuring the position of the test box 10 so that the robotic arm can transfer the workpiece 01 to the workpiece test position 12 of the test box 10.

[0094] In one embodiment, matching positioning bumps (not shown) and positioning grooves (not shown) are respectively provided on the test box 10 and the positioning post. When positioning the test box 10, the positioning bumps and the positioning grooves match to ensure accurate positioning of the test box 10.

[0095] In one embodiment, a lifting assembly (not shown) is provided below the second bracket 22, including a lifting push block and a lifting driving member for lifting the test box 10 on the second bracket 22 in the vertical direction. When the test box 10 needs to be lifted, the lifting driving member drives the lifting push block to move upward. After the lifting push block contacts the bottom surface of the test box 10, it continues to move upward to push the test box 10 upward. By providing the lifting push block, the test box 10 can be lifted to a specified height to adapt to the heights of different transfer devices when the test box 10 needs to be transferred (such as transferring the test box 10 from the first carrier platform 20 to the first feeding mechanism 30; or transferring the test box 10 from the second feeding mechanism 70 to the second carrier platform 60).

[0096] In one embodiment, the test device includes a test cartridge 10, a test chamber 40, a first feeding mechanism 30 docked with the feeding port 41 of the test chamber 40, a second feeding mechanism 70 docked with the discharging port 47 of the test chamber 40, a first carrying platform 20, a second carrying platform 60, a first functional test mechanism 80, a second functional test mechanism 90, a detection mechanism 110, and an electronic device 50. Among them, on the first carrying platform 20, there are carried a first functional test mechanism 80 disposed on a first bracket 21, a second bracket 22 adjacent (side by side) to the first bracket 21 in the longitudinal direction (for movably loading the test cartridge 10), and a detection mechanism 110 installed adjacent to the second bracket 22 in the transverse direction. One end of the first feeding mechanism 30 is docked with the second bracket 22 on the first carrying platform 20, and the other end is docked with the feeding port 41 of the test chamber 40. On the second carrying platform 60, there are carried a second functional test mechanism 90 disposed on a first bracket 21, and a second bracket 22 adjacent (side by side) to the first bracket 21 in the longitudinal direction (for movably loading the test cartridge 10). One end of the second feeding mechanism 70 is docked with the second bracket 22 on the second carrying platform 60, and the other end is docked with the discharging port 47 of the test chamber 40. The electronic device 50 can be randomly set around the test device or can be a mobile device. Optionally, in order to improve the efficiency of the test device in transferring the test cartridge 10, a transfer mechanism 100 is provided between the first carrying platform 20 and the second carrying platform 60 for transferring the test cartridge 10, after all the workpieces 01 that have completed the test in the test chamber 40 have been disassembled, from the second carrying platform 60 to the first carrying platform 20, so that the test cartridge 10 can be reloaded with the next batch of workpieces 01 that need to enter the test chamber 40 for testing. In one embodiment, the transfer mechanism 100 can be implemented using the same components as the first feeding mechanism 30, such as a feeding belt unit and a ratchet conveying unit.The test box 10 moves cyclically on various components of the test equipment. Specifically: The initial position of the test box 10 is on the second bracket 22 of the first loading platform 20. After the robotic arm transfers several workpieces that have been tested and passed the test on the first functional test mechanism 80 to the test box 10, the first feeding mechanism 30 is activated to transfer the test box 10 from the first loading platform 20 to the feeding port 41 of the test chamber 40. Then, the workpiece 01 loaded on the test box 10 will be tested in the test chamber 40 (trial operation, such as running for a preset time period. If there is no error after running the preset time period, the performance of the workpiece 01 can be considered qualified and it can be put into market use). After the test is completed, the test chamber 40 transfers the test box 10 to the discharge port 47, and the second feeding mechanism 70 is activated to transfer the test box 10 from the discharge port 47 of the test chamber 40 to the second bracket 22 of the second loading platform 60. Then, the robotic arm is used to disassemble the workpiece 01 on the test box 40, and the disassembled workpiece is loaded onto the second functional test mechanism 90 for functional testing. At the same time, the empty test box 10 is transferred to the second bracket 22 of the first loading platform 20 (initial position) through the transfer mechanism 100 and contacts the detection mechanism 110 to test the test box 10 and each workpiece test position 12 on the test box 10. It can be understood that the moving path of the test box 10 on the test equipment is a closed path and can be used cyclically. Optionally, there are multiple test boxes 10 on the test equipment. Preferably, the number of test boxes 10 corresponds to the number of test stations 441 included in the test chamber 40. When the test equipment is running, each test box 10 moves cyclically on each component in turn.

[0097] Please refer to Figure 14 , the embodiment of the present application further provides a test method using the test equipment provided in the above embodiment, including:

[0098] S101 Load at least one workpiece 01 on the workpiece test position 12 of the test box 10.

[0099] S102 Transfer the test box 10 loaded with at least one workpiece 01 to the feeding port 41 of the test chamber 40 through the first feeding mechanism 30.

[0100] S103 Transfer the test box 10 loaded with at least one workpiece 01 from the feeding port 41 to the test station through the conveying mechanism 46 of the test chamber 40, so that the test contacts 11 on the test box 10 are electrically connected to the test connectors on the test station 441.

[0101] S104 Supply power to the test box 10 located at the test station within a preset time period to operate at least one workpiece 01.

[0102] In S105, if the test box 10 reports an error during the power supply process, the workpiece 01 on the workpiece test position 12 corresponding to the error message is determined as the workpiece with a failed test.

[0103] Specifically, the test equipment can be docked with the production line for assembling workpieces, and a robotic arm is directly used to transfer the assembled workpieces from the production line to the test equipment for testing. The start, stop, and operation processes of each component on the test equipment can be controlled by a numerical control device.

[0104] In step S101, to improve the test efficiency, the test box 10 is designed to include multiple workpiece test positions 12. Each cycle of the test box 10 on the test equipment can be fully loaded, empty, or semi-empty with the workpiece 01. For example, a robotic arm is used to sequentially load each workpiece 01 onto the test box 10 until all the workpiece test positions 12 on the test box 10 are loaded with workpieces 01, or until the number of workpieces 01 loaded on the test box 10 reaches a preset number. Optionally, an empty test box 10 (without loading any workpiece 01) can be conveyed into the test room 40 to test whether the test box 10 operates normally using the test room 40.

[0105] In step S102, the first feeding mechanism 30 is used to convey the test box 10 to the feeding port 41 of the test room 40. Optionally, in an embodiment, a robotic arm can be used to replace the first feeding mechanism 30 to transfer the test box 10 from the first carrying platform 20 to the feeding port 41 of the test room 40.

[0106] In step S103, the test room 40 includes multiple test stations 441. Each test box 10 has a corresponding test station 441 in the test room, that is, each cycle of the test box 10 repeats the transfer to the same test station 441. This configuration can quickly infer whether the abnormality occurs in the test station 441 on the test room 40 or in the test box 10 when an abnormal test is found. Optionally, each test box 10 can also be randomly transferred to any empty test station 441 in the test room 40. After the conveying mechanism 46 transfers the test box 10 to the test station 441, the test contacts 11 on the test box 10 will be electrically connected to the test connectors on the test station 441.

[0107] In step S104, after the test connector on any test station 441 is electrically connected to the test contacts on the test box 10, the power supply system is started to supply power to the test box 10 located on the test station 441 within a preset time period to operate the workpiece 01 loaded on the test box 10 for a preset time period. This operation process simulates the operation process of the workpiece 01 in the real usage environment.

[0108] In step S105, the electronic device 50 will continuously receive signals fed back by the test station during the power supply process, which specifically includes the operation information of each workpiece 01. When the electronic device 50 receives an error message, it parses the error message and determines the workpiece 01 on the workpiece test position 12 of the test cassette 10 corresponding to the error message as the workpiece that fails the test. Optionally, to remind to process the workpiece that fails the test, the electronic device 50 can also issue an error warning. If no error message is generated at the end of the power supply process, it is determined that the corresponding workpiece 01 is a workpiece that passes the test and can be put into the market for use.

[0109] By implementing the above steps, by using the test room 40 to conduct a trial operation test on the workpiece 01, it is beneficial to improve the qualified rate of the workpiece 01. Among them, using the test cassette 10 to load the workpieces for batch testing is beneficial to improve the test efficiency; by processing the fed-back information through the electronic device 50, it is beneficial to improve the accuracy of identifying the workpieces that fail the test.

[0110] In one embodiment, the test method further includes:

[0111] (1) After the power supply ends, the conveying mechanism 46 is used to transfer the test cassette 10 from the test station to the discharge port 47 of the test room 40.

[0112] (2) The second feeding mechanism 70 is used to convey the test cassette 10 from the discharge port 47 of the test room 40 to the second carrying platform 60.

[0113] (3) At least one workpiece 01 is disassembled from the workpiece test position 12 of the test cassette 10.

[0114] Specifically, when the workpiece 01 finishes the test in the test room 40, the test cassette 10 can be manually taken out from the test station 441 and the workpieces on the test cassette 10 can be disassembled. To improve the test efficiency, this embodiment provides a method for processing the test cassette 10 and the workpiece 01 after the test, that is, after the power supply ends, the conveying mechanism 46 is started to transfer the test cassette 10 from the test station 441 to the discharge port 47 of the test room 40, and then the second feeding mechanism 70 is used to convey the test cassette 10 from the discharge port 47 of the test room 40 to the second bracket 22 of the second carrying platform 60; when the test cassette 10 is stably loaded on the second bracket 22, a robotic arm is used to disassemble all the workpieces 01 on the test cassette 10. Optionally, the second feeding mechanism 70 can be replaced by a robotic arm.

[0115] In one embodiment, the feed inlet 41 and the discharge port 47 of the test room 40 are provided in a matching manner. To dock more production lines for assembling workpieces of different models, other matching feed inlets 41 and discharge ports 47 can be opened at other positions of the test room 40 to improve the utilization rate of the test room 40.

[0116] In one embodiment, before step S101 loads at least one workpiece 01 onto the workpiece test position 12 of the test cartridge 10, it further includes:

[0117] A Place at least one workpiece 01 on the first functional test mechanism 80 for functional testing.

[0118] Step S101 loads at least one workpiece 01 onto the workpiece test position 12 of the test cartridge 10, including:

[0119] B Determine that at least one workpiece 01 has passed the functional test, and place at least one workpiece 01 on the workpiece test position 12 of the test cartridge 10 where no workpiece is loaded.

[0120] Specifically, to improve the utilization rate of the test chamber 40 and the test efficiency, before loading the workpiece 01 onto the test cartridge 10 and sending it into the test chamber 40 for testing (simulating the actual environment for trial operation), place the workpiece 01 on the first functional test mechanism 80 for functional testing (such as testing resistance, voltage, and current performance). Only the workpiece 01 that passes the functional test can be transferred to the workpiece test position 12 of the test cartridge 10 by the robotic arm.

[0121] In one embodiment, after step (3) disassembles at least one workpiece 01 from the workpiece test position 12 of the test cartridge 10, it further includes:

[0122] Determine that at least one workpiece 01 is a workpiece 01 that has passed the test, and place at least one workpiece 01 on the second functional test mechanism 90 for functional testing.

[0123] Specifically, to improve the qualified rate of the workpiece 01 put on the market, transfer the workpiece 01 that has completed the test in the test chamber 40 to the second functional test mechanism 90 for functional testing. Optionally, the functional test functions that can be performed on the first functional test mechanism 80 and the second functional test mechanism 90 are the same. The functional test performed on the first functional test mechanism 80 can be understood as a preliminary test (simply testing whether it conducts electricity, etc.), and the functional test performed on the second functional test mechanism 90 can be understood as a retest (further testing the various performances of the workpiece 01). Specifically, when the test cartridge 10 is stably transferred to the second bracket 22 of the second carrier platform 60, use the robotic arm to transfer the workpiece 01 that has completed the test in the test chamber 40 and passed the test on the test cartridge 10 to the second functional test mechanism 90; other workpieces 01 that have failed the test will be transferred to the failed workpiece processing area by the robotic arm.

[0124] In one embodiment, after step (3) disassembles at least one workpiece 01 from the workpiece test position 12 of the test cartridge 10, it further includes:

[0125] Transfer the test box 10 from the second bearing platform 60 to the first bearing platform 20, and use the detection mechanism to detect whether the test box 10 and each workpiece test position 12 on the test box 10 are operating normally.

[0126] If the detection result of any workpiece test position 12 is abnormal, mark the workpiece test position 12 and leave the workpiece test position 12 vacant when loading workpiece 01 on the test box 10 in the next round.

[0127] Specifically, considering that the test box 10 may be damaged after multiple uses, to improve the accuracy of the test, after removing the workpiece 01 on the test box 10 through step (3), before the test box 10 is put into the next round of use, the test box 10 and each workpiece test position 12 on the test box 10 are tested. Specifically, the transfer mechanism 100 is used to transfer the empty test box 10 from the second bracket 22 of the second bearing platform 60 to the second bracket 22 of the first bearing platform 20. When the test box 10 is stably loaded on the second bracket 22 of the first bearing platform 20, the test contact 11 of the test box 10 will be electrically connected to the third thimble 111 of the detection mechanism 110, and then the detection mechanism 110 is started to detect the test box 10 and each workpiece test position 12 on the test box 10. The detection may include whether the electrical connection is stable, whether the signal transmission is normal, etc. If the overall detection of the test box 10 is abnormal, the test box 10 is removed from the test equipment; if only the detection result of a certain workpiece test position 12 on the test box 10 is abnormal, mark the workpiece test position 12 and leave the workpiece test position 12 vacant when loading workpiece 01 on the test box 10 in the next round. When the number of workpiece test positions 12 with abnormal detection on the test box 10 exceeds the preset threshold (it can also be a proportion, such as the abnormal workpiece test positions 12 account for 50% of the total), the test box 10 is removed.

[0128] The above are only some embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present application.
