Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fuse production, in particular to a fuse testing labeling device. Background Art
[0002] Fuses are electrical components installed in circuits to ensure safe operation of circuits. When a circuit fails or is abnormal, the current continues to rise, which may damage the electrical components in the circuit. If the fuse is correctly installed in the circuit, the fuse will melt and cut off the current when the current abnormally rises to a certain height, thereby protecting the safe operation of the circuit.
[0003] In order to ensure that the fuse tube is qualified before leaving the factory, the fuse is generally tested before leaving the factory to ensure that the resistance value of the fuse is within the range; at the same time, the existing fuses need to be labeled before leaving the factory, and the labeling is generally carried out separately from the resistance detection, resulting in more fuse production processes and little improvement in production efficiency.
[0004] Moreover, the existing fuse test usually uses two test needles, which are respectively set at the two ends of the fuse flowing on the assembly line to test the resistance; however, the position of the fuse on the assembly line is easy to change during the transportation process, which will cause the contact point between the test needle and the two ends of the fuse to change, and ultimately lead to inaccurate testing.

DETAILED DESCRIPTION
[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.
[0031] like Figures 1 to 5 As shown, a fuse testing labeling device of the utility model comprises a machine platform 1, a transmission device 2, a testing device 3, a labeling device 4 and a three-axis adjustment mechanism 5.
[0032] The transmission device 2 , the testing device 3 , the labeling device 4 and the three-axis adjustment mechanism 5 are all installed on the table of the machine 1 .
[0033] The transmission device 2 includes a conveyor belt 21, and the conveyor belt 21 is used to transport the fuse 6;
[0034] The testing device 3 and the labeling device 4 are respectively arranged corresponding to two sides of the fuse tube body 61 at the testing station S on the conveyor belt 21;
[0035] The testing device 3 includes two groups of testing probes 31, each group of testing probes 31 moves perpendicular to the conveying direction of the conveyor belt 21, and the two groups of testing probes 31 are movable and extend to the two end terminals 62 of the fuse 6;
[0036] The labeling device 4 includes a pressing plate 41 , which moves perpendicularly to the conveying direction of the conveyor belt 21 . The pressing plate 41 is used to attach a label (not shown) to the side of the fuse tube body 61 .
[0037] Thus, by setting the test device 3 and the labeling device 4 corresponding to the fuse 6 at the test station S, the fuse 6 can be labeled by the pressing plate 41 of the labeling device 4 while the test probe 31 of the test device 3 is used to test the resistance of the fuse 6, thereby saving production processes and improving production efficiency. In addition, the fuse 6 can be transported in batches by the conveyor belt 21 to achieve batch production.
[0038] like Figure 3 and Figure 4 , the test probe 31 of the test device 3 is arranged on the horizontal side of the conveyor belt 21 at the test station S, and corresponds to the horizontal side of the fuse 6 at the test station S; a baffle 22 is arranged on the other horizontal side of the conveyor belt 21 at the test station S; specifically, in this embodiment, the conveyor belt 21 extends longitudinally and transports the fuse 6 along the longitudinal direction, the test station S is arranged in the middle of the conveyor belt 21, the test device 3 is located at the horizontal front side of the conveyor belt 21, and the baffle 22 is arranged at the horizontal rear side of the conveyor belt 21, so that when the test probe 31 abuts against the fuse 6, the baffle 22 can block the fuse 6. Of course, the installation positions of the baffle 22 and the test device 3 can also be swapped.
[0039] The pressing plate 41 of the labeling device 4 is arranged vertically above the testing station S of the conveyor belt 21 and corresponds to the top surface of the fuse tube body 61 at the testing station S. Therefore, the fuse 6 is placed on the top surface of the conveyor belt 21 for transmission, and the pressing plate 41, which is perpendicular to the conveyor belt 21 from top to bottom, can be vertically movable to press the label tightly against the top surface of the fuse tube body 61.
[0040] Another example Figure 5 and Figure 6As shown, in order to improve the accuracy of resistance measurement, each group of test probes 31 of this embodiment includes two test probes 31, and the two groups of test probes 31 have four test probes 31 in total, which are used to implement four-terminal resistance measurement.
[0041] Thus, by using four test probes 31, when the fuse 6 is transferred to the test station S along the conveyor belt 21, the test device 3 controls the four test probes 31 to extend, and two by two are respectively against the terminals 62 at both ends of the fuse 6, and the four test probes 31 can be connected to the test circuit (not shown), thereby using the four test probes 31 to implement the four-terminal resistance measurement method, and the accurate resistance of the fuse 6 can be tested, and even if the fuse 6 is skewed and the contact points of the four test probes 31 change, it will not affect the accuracy of the measurement. The four-terminal resistance measurement method is a prior art, and its specific principle will not be repeated here.
[0042] In order to realize automation, the present embodiment provides a sensor 7 for detecting the fuse 6 at the test station S. The sensor 7 detects whether the fuse 6 passes through the test station S, and can control whether the conveyor belt 21 is paused, and control the synchronous operation of the test device 3 and the labeling device 4.
[0043] like Figure 5 In this embodiment, the conveyor belt 21 is provided with a plurality of spaced stoppers 211, which are located below the terminal 62 on one side of the fuse 6 and abut against the end surface of the fuse tube 61. The stoppers 211 are provided to facilitate positioning and placing the fuse 6. In this embodiment, each stopper 211 is located on the left side of the fuse 6 in the longitudinal direction, so that the fuse 6 can move rightward along with the conveyor belt 21 in the longitudinal direction.
[0044] Also, see Figure 2 and Figure 6 The test device 3 further includes a telescopic cylinder 32 and a telescopic bracket 33; the output end 322 of the telescopic cylinder 32 is detachably connected to the telescopic bracket 33, and controls the telescopic bracket 33 to move along the conveying direction perpendicular to the conveyor belt 21; a set of test probes 31 are respectively installed on both sides of the telescopic bracket 33. The telescopic bracket 33 is replaceable, which is convenient for adaptive adjustment for fuses 6 of different widths, so that the test probes 31 on both sides can be extended to abut against the terminals 62 at both ends of the fuse 6.
[0045] The conveyor belt 21 is connected to conveyor belt fixing frames 23 on both sides thereof, and rollers at both ends of the conveyor belt 21 (not shown) can be respectively arranged between the two ends of the two conveyor belt fixing frames 23, and the main body 321 of the telescopic cylinder 32 can be connected and fixed to the conveyor belt fixing frames 23 by means of a mounting frame 34, and the output end 322 of the telescopic cylinder 32 is arranged horizontally toward the conveyor belt 21.
[0046] The labeling device 4 of this embodiment further includes a label conveying mechanism 42, which is used to output labels to the pressing plate 41. The labeling device 4 can adopt the existing technical structure, and the specific working principles of the pressing plate 41 and the label conveying mechanism 42 will not be described in detail here.
[0047] In order to facilitate the adjustment of the labeling position, the present embodiment further includes a three-axis adjustment mechanism 5 for adjusting the position of the pressing plate 41 of the labeling device 4 .
[0048] Specifically, the three-axis adjustment mechanism 5 includes a transverse linear module 51, a vertical linear module 52, and a longitudinal linear module 53. The transverse linear module 51 is perpendicular to one side of the conveyor belt 21, the vertical linear module 52 is connected to a transverse slider 511 of the transverse linear module 51, the longitudinal linear module 53 is connected to a vertical slider 521 of the vertical linear module 52, and the labeling device 4 is connected to a longitudinal slider 531 of the longitudinal linear module 53. Therefore, the spatial position of the labeling device 4 can be adjusted by using the transverse linear module 51, the vertical linear module 52, and the longitudinal linear module 53 to meet production requirements.
