Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the embodiment, the operator is used as a reference, and the direction close to the operator is a proximal end, and the direction away from the operator is a distal end.

As shown in fig. 1 to 4, the present invention discloses a sorting tool for resistance value testing, which comprises a worktable 100; one end of the workbench 100 is provided with a feeding mechanism 1, and the feeding mechanism 1 at least comprises a feeding cylinder 11. Specifically, the charging cylinder 11 is fixed to a cylinder mounting plate 110, and a cylinder shaft of the charging cylinder 11 penetrates the cylinder mounting plate 110 and the table 100. The feeding platform 111 for placing the resistors is fixed on the cylinder shaft of the feeding cylinder 11, and because a stack of resistors to be detected is placed on the feeding platform 111, the resistors and the weight of the feeding platform 111 are concentrated on the cylinder shaft, the cylinder shaft may be bent or even broken after long-term use, and the service life of the feeding cylinder 11 is affected. In order to solve the above problem, as shown in fig. 3 to 4, at least two lifting rods 1101 parallel to each other are disposed between the cylinder mounting plate 110 and the loading platform 111, and a cylinder shaft is located between a set of the lifting rods 1101. The jacking rod 1101 is preferably telescopic, that is, the feeding cylinder 11 drives the jacking rod 1101, the feeding platform 111 and the resistor to lift along the setting direction of the feeding cylinder 11. The pressure of the feeding cylinder 11 is shared by the jacking rod 1101 to prolong the service life of the feeding cylinder.

As shown in fig. 1 and 4, the feeding mechanism 1 further includes a fixed plate 12, a moving plate 13 slidably disposed on the fixed plate 12, and a limit plate 14 disposed on the moving plate 13. Specifically, the fixed plate 12 is provided with at least one slide rail, the slide rail is provided with a slider moving along the installation direction of the slide rail, and the slider is fixedly connected with the moving plate 13. The fixed plate 12 is fixed on the upper surface of the worktable 100, and a driving cylinder 121 for driving the moving plate 13 to move along the Y-axis direction is arranged on the fixed plate 12; a connecting block is fixed on the cylinder shaft of the driving cylinder 121, and the connecting block is fixedly connected with the moving plate 13.

As shown in fig. 1 to 2, through holes for allowing the feeding platform 111 to pass through are formed in the moving plate 13 and the limiting plate 14, and at least two through holes for preventing the resistor to be detected are formed in the moving plate 13. And the through hole and the resistor placed therein are moved to the loading platform 111. The distance between the feeding platform 111 and the limiting plate 14 is equal to the maximum lifting stroke of the feeding cylinder 11. The limiting plate 14 and the moving plate 13 are fixedly connected through a set of support rods 134. Therefore, when the resistors reach the feeding platform 111, the feeding cylinder 11 is started to drive the resistors to move towards the through holes of the limiting plates 14 until the uppermost resistor is located in the through hole of the limiting plate 14, that is, a feeding operation is completed, and when all the resistors on the feeding platform 111 move into the limiting plate 14, that is, a batch feeding operation is completed. In the batch loading operation process, the resistor of the next batch to be detected can be placed in the other through hole on the moving plate 13, so that the waiting time is saved, and the working efficiency is improved.

As shown in fig. 2 to 3, after the loading is completed, the resistor to be detected needs to be placed on the test platform 21, and since the resistor is mostly used for an electronic resistor, the manual moving will have a certain influence on the resistance of the resistor, and further affect the accuracy of the detection, so the manual moving of the resistor is not feasible. The utility model discloses in be provided with and be used for carrying out moving to resistance and carry mechanism 4, move and carry mechanism 4 to be located feed mechanism 1's top, be used for with the resistance of limiting plate 14 department removes extremely test platform 21 department. The transfer mechanism 4 includes a guide rail 42, a motor 43 provided at one end of the guide rail 42, and a movable suction pad 41 slidably provided on the guide rail 42. The number of the movable suction cups 41 is at least two, and the movable suction cups 41 are driven by the motor 43 to move along the arrangement direction of the guide rail 42. The movable sucker 41 reciprocates between the feeding mechanism 1 and the detection mechanism 2 or between the detection mechanism 2 and the discharging mechanism 3, and grabs and moves the resistor on the corresponding mechanism to the next mechanism. A first air cylinder 411 is arranged between the movable suction cup 41 and the guide rail 42, and the first air cylinder 411 drives the movable suction cup 41 to move along the Z-axis direction.

A pressing cylinder 44 is vertically fixed on the side wall of the guide rail 42, and the cylinder axis of the pressing cylinder 44 faces downwards. After the pressing cylinder 44 is started, the test ram 441 at the cylinder shaft of the pressing cylinder is driven to move up and down.

As shown in fig. 1 to 3, a detection mechanism 2 is further disposed on the working platform 100, and the detection mechanism 2 is located at one side of the feeding mechanism 1. The detection mechanism 2 comprises the test platform 21, a test air cylinder 22 arranged below the test platform 21 and a test assembly 23 fixed on the air cylinder shaft of the test air cylinder 22. The testing platform 21 is connected with the workbench 100 through a set of guide rods 102, and the testing platform 21 and the limiting plate 14 are located on the same axis. The testing assembly 23 includes a probe mounting seat 231 and a probe 232 disposed on the probe mounting seat 231, and a free end of the probe 232 penetrates the testing platform 21 and contacts with a resistor carried on the testing platform 21.

As shown in fig. 3, since the probe 232 is made smaller, if the resistor is not fixed, the probe 232 may pass through the gap between the resistors, i.e. cannot contact the resistors; or the probe 232 contacts with other parts, which causes the probe 232 to be damaged or even broken. For avoiding the above-mentioned unfavorable condition's emergence, the utility model discloses the solution of taking is: before the probe 232 is used for detecting the resistance, the pressing cylinder 44 is started, and the resistance to be detected is pressed through the testing pressure head 441; by activating the testing cylinder 22, the probe 232 is driven to move towards the resistor and contact with the resistor, and the resistance value of the resistor is measured.

After the resistance value of the resistor is measured, the resistors with different resistance value ranges need to be placed in different places so as to be distinguished, and meanwhile, the resistors are conveniently used on different equipment in later periods. But classify the resistance through manual operation and then can't guarantee categorised degree of accuracy, and work efficiency is lower, and manufacturing cost is great. Therefore, the present invention adopts the blanking mechanism 3 shown in fig. 1 to 3, and the blanking mechanism 3 is located on the working table 100.

As shown in fig. 1, 2 and 4, the blanking mechanism 3 at least includes a conveying line 31 on one side of the detecting mechanism 2 and a set of collecting frames 32 symmetrically disposed on both sides of the conveying line 31. The width of the feed line 31 is smaller than the length of the resistor. Different resistors with different resistance ranges are stored in different collecting frames 32, that is, the resistance ranges of the resistors stored in the same collecting frame 32 are the same. The classifying operation of the resistors is performed through a group of blanking cylinders 34 in the blanking mechanism 3, which correspond to the collecting frames 32 one by one, that is, the blanking mechanism 3 further comprises the blanking cylinders 34; a push plate 321 is fixed at the cylinder shaft of the blanking cylinder 34, the push plate 321 is located on the outer side of the side wall of the conveying line 31, and one side of the resistor placed on the conveying line 31 is lifted up through the push plate 321, so that the resistor is inclined and pushed into the collecting frame 32 corresponding to the blanking cylinder 34 on the opposite side of the push plate 321.

The collecting frame 32 is obliquely arranged on two sides of the conveying line 31, and the collecting frame and the conveying line are connected through a blanking channel 33. The push plate 321 penetrates through the blanking channel 33 and is in contact with the resistor on the conveying line 31.

The conveying line 31 is driven by a servo motor 311 to move in a direction away from the detection mechanism 2. In order to prevent the resistors placed on the conveying line 31 from being spaced too closely, so that the push plate 321 lifts two resistors, thereby causing classification errors, partition plates 312 are arranged on the conveying line 31 at equal intervals, and one resistor is placed between two adjacent partition plates 312.
