Description

Technical Field

[0001] The present invention relates to the technical field of resistor manufacturing, and in particular to chip resistor assembly equipment and an assembly method. Background Art

[0002] like Figure 1 and Figure 2 As shown, the existing chip resistor includes a string rod 5 and multiple parallel resistor sheets 3, and also includes an insulating member 4 such as a porcelain part and a mica ring. The insulating member 4 includes a seat body 41 and a protrusion 42 of an integrated structure, and the seat body 41 is provided with a groove. The end of the resistor sheet 3 is provided with a mounting hole, and the protrusion 42 of the insulating member 4 passes through the mounting hole of the resistor sheet 3 and is inserted into the groove of the adjacent insulating member 4, so that two adjacent resistor sheets 3 are separated by the seat body 41, and the string rod 5 and the resistor sheet 3 are separated by the protrusion 42. The string rod 5 strings together the multiple resistors and the insulating member 4, and nuts are screwed on both ends of the string rod 5 to lock the insulating member 4 and the resistor sheet 3. The existing method of assembling the above chip resistors is to open two holes on the table, first screw one end of the string rod into the nut and then insert it into the hole, the nut is against the table so that the string rod stands on the table, and then the staff sequentially inserts the insulating part and the resistor sheet into the string rod, repeats the insertion of the two, and finally screws the nut into the end of the string rod away from the table to lock the resistor sheet. The assembly is completed, and finally the staff lifts the assembled chip resistor out as a whole. The above assembly method has the following disadvantages: 1. When the string rod stands on the table and multiple resistors are put on, the stacked resistors tend to move laterally, and the string rod is subjected to a large radial force, which can easily cause the string rod to bend and deform, thereby reducing the quality of the chip resistor; 2. There is a mica layer on the outside of the string rod for insulation. Repeated insertion of resistors can easily scratch the mica layer, resulting in reduced insulation effect of the resistor; 3. If there are a large number of resistors, the stacked resistors are prone to tipping over, causing damage to the resistor 3 or injuring the operator; 4. Generally, two workers are required to work together, one of whom is responsible for inserting the resistor into the string rod, and the other is responsible for inserting the insulating part into the string rod. The working speeds of the two workers are often different, and the faster one needs to wait for a short time. For example, the worker who inserts the insulating part is relatively fast, and after each insertion of the insulating part, he can only wait for another worker to insert the resistor before inserting the next insulating part, which greatly reduces the assembly efficiency. Summary of the invention

[0003] In view of the above technical problems in the prior art, the present invention provides a chip resistor assembly device and an assembly method, which can improve the assembly speed and ensure the quality of the assembled resistor.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0016] Beneficial effects of the present invention:

[0030] The present invention is described in detail below in conjunction with specific embodiments and drawings.

[0031] The chip resistor assembly equipment of this embodiment is as follows Figure 3 As shown, it includes a base 1, the top surface of the base 1 is an inclined surface, and a plurality of sliding seats 2 are arranged obliquely on the inclined surface, wherein the left sliding seat 21 located on the leftmost side is fixed to the base 1, and the other sliding seats 2 can slide on the top surface of the base 1. Figure 5 As shown, a limiting hook 23 is provided on one side of the sliding seat 2, and a limiting groove 24 is provided on the other side. The limiting hook 23 of the sliding seat 2 is located in the limiting groove 24 of the adjacent sliding seat 2, and the limiting hook 23 can move in the limiting groove 24. The base 1 is provided with a stopper 11. When the right sliding seat 22 located on the far right side just moves to abut against the stopper 11, the limiting hook 23 of each sliding seat 2 clamps the limiting groove 24 of the adjacent sliding seat 2, so that the two adjacent sliding seats 2 are in place at the same preset distance in one step, forming a Figure 3 The multiple sliding seats 2 shown are in a state of being away from each other. Figure 4 As shown, the sliding seat 2 is provided with a slot 25 for inserting the resistor 3 , and the top of the sliding seat 2 is provided with a semicircular groove 26 for placing the insulating member 4 .

[0032] During assembly, the staff pulls the right sliding seat 22 to stick to the stopper 11 to form a Figure 3 The plurality of sliding seats 2 are shown in a state where they are separated from each other, and then resistor sheets 3 are inserted into the slots 25 of the respective sliding seats 2 to form Figure 6 In the state shown, after the resistor 3 is inserted into the slot 25, the side of the resistor 3 is against the side of the sliding seat 2, and the mounting hole of the resistor 3 is aligned with the groove 26. Multiple resistors 3 are inserted into the slots 25 of different sliding seats 2 facing downward, avoiding the problem of resistors stacked vertically and easily tipping over in the traditional assembly method, ensuring the safety of the staff. Figure 7As shown, during the insertion of the resistor 3 or after the resistor 3 is installed, the insulating member 4 is placed in the groove 26 of each sliding seat 2. Since there is enough distance between two adjacent sliding seats 2, and the distance between two adjacent inserted resistors 3 is greater than the length of the insulating member 4, the action of inserting the resistor 3 and the action of placing the insulating member 4 do not interfere with each other. Even if the working speed of the staff responsible for inserting the resistor 3 is different from that of the staff responsible for placing the insulating member 4, the person with the faster speed does not need to pause and wait, thereby improving work efficiency. Since the top surface of the base 1 is inclined, the insulating member 4 can be more easily inserted into the mounting hole of the resistor 3. After completing the above work of inserting the resistor 3 and placing the insulating member 4, the staff pushes the right sliding seat 22 to move along the inclined surface to the upper left until the two adjacent sliding seats 2 fit together, and then manually operates the locking pin 12 on the base 1 to clamp the right sliding seat 22, forming a Figure 7 The multiple sliding seats 2 shown in the figure are close to each other. In this state, the protrusion of the insulating member 4 passes through the mounting hole of the resistor 3 and is inserted into the groove 26 of the adjacent insulating member 4. The two end surfaces of the seat body of the insulating member 4 respectively abut against two adjacent resistors 3. Then, the string rod 5 passes through the insulating member 4, and nuts 6 are respectively locked on the two ends of the string rod 5, so as to lock the insulating member 4 and the resistor 3, forming a structure as shown in FIG. Figure 8 As shown in the state, the whole chip resistor is assembled. It can be seen from the above that the string rod 5 is installed after the resistor sheet 3 and the insulating member 4 are arranged, thus avoiding the problem of the string rod 5 being bent and deformed by excessive radial force in the traditional assembly method, and the mica layer on the surface of the string rod 5 will not be scratched, thus ensuring the overall quality of the chip resistor.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
