The testing and laser marking in the prior art are carried out in sequence along the assembly line. In order to ensure the accuracy of the test, the material tape needs to be temporarily paused on the test device; in order to ensure the accuracy of the laser marking, the material tape needs to be temporarily paused under the laser marking device; in this way, the test and laser marking need to be paused once each, and each capacitor product will make such a pause, which will make the entire production line take a long time and the production efficiency is low; on the other hand, the testing equipment and the laser marking equipment are arranged in sequence along the assembly line, and the testing equipment and the laser marking equipment need to occupy the workshop space alone, which makes the entire production line occupy a large area and the site cost is high; and a guiding device is also required to guide the material tape to the bottom of the laser marking device, and the overall equipment cost is also high. Utility Model Content
[0003] The purpose of the utility model is to solve the above-mentioned problems and shortcomings, and to provide an integrated electrical performance testing and laser marking device. By arranging the laser marking device above the testing device, when the electrical properties of the capacitor products are tested, the qualified capacitor products can be laser marked at the same time, thereby saving time and improving production efficiency; in addition, placing the laser marking device above the electrical testing device can effectively utilize the space above the electrical testing device, thereby reducing the floor space of the capacitor production line and reducing the site cost expenditure; and there is no need to additionally configure a material belt guiding device between the laser marking device and the electrical testing device, which is conducive to reducing equipment costs.
[0004] The technical solution of the utility model is implemented as follows: an integrated device for electrical performance testing and laser marking, which is characterized in that it includes a laser marking device and an electrical performance testing device, wherein the laser marking device is placed above the electrical performance testing device.
[0005] Furthermore, the electrical testing device comprises a base, two test terminals, and a guide rail, wherein the base is placed above the guide rail, the two test terminals are arranged on the front wall of the base, and the lower ends of the two test terminals are placed outside the guide rail.
[0006] Furthermore, the test terminal is composed of an inclined rod and a horizontal rod integrally connected to the inclined rod, the inclined rod is arranged on the front wall of the base, and the length direction of the horizontal rod is in the same direction as the guiding direction of the guide rail and is arranged on the outside of the guide rail.
[0007] Furthermore, the inclined rods of the two test terminals are arranged to be inclined toward the material strip input direction, and the horizontal rods on the two test terminals are formed by bending the lower ends of the corresponding inclined rods toward the material strip output direction.

[0013] Beneficial effects of the utility model:
[0014] First, when conducting electrical tests on capacitor products on the material strip, in order to ensure the accuracy of the test, the material strip needs to be temporarily paused so that the test terminals can form stable electrical contact with the capacitor products to complete the test; by placing the laser marking device above the electrical testing device, the capacitor products can be marked during the above pause time without the need to pause the material strip for laser marking of the capacitor products. This can shorten the time of the entire capacitor production line and thus improve the production efficiency of the capacitor products.
[0015] Second, placing the laser marking device above the electrical testing device can make full use of the three-dimensional space of the capacitor production line, reduce the length of the entire production line, and thus reduce the floor space of the entire production line, which is conducive to saving site costs.
[0016] Third, since the capacitor products are laser marked at the same time as the electrical tests, there is no need to guide the material strip from the electrical testing device to the laser marking device. Therefore, there is no need to equip the laser marking device with an additional material strip guiding device between the laser marking device and the electrical testing device. Therefore, the equipment cost can be reduced, which helps to save production costs and enhance the company's market competitiveness. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention.
[0022] like Figure 1 As shown, an integrated device for electrical performance testing and laser marking, in order to achieve the purpose proposed by the utility model, comprises a laser marking device 1 and an electrical performance testing device 2, wherein the laser marking device 1 is placed above the electrical performance testing device 2. In this way, when the capacitance product is tested for capacitance, it can be laser marked at the same time, thereby saving time and improving production efficiency; it can also make full use of the three-dimensional space of the production line, thereby shortening the length of the production line and saving floor space, and there is no need to separately configure a material belt guiding device for the laser marking device, thereby saving equipment costs and further reducing production costs.
[0023] like Figure 2 , Figure 3 , Figure 4 As shown, the electrical testing device 2 includes a base 21, two test terminals 22, and a guide rail 23. The base 21 is placed above the guide rail 23, and the two test terminals 22 are arranged on the front wall of the base 21, and the lower ends of the two test terminals 22 are placed outside the guide rail 23. When the material strip is conveyed on the guide rail 23, the exposed pins on the material strip are placed in front of the guide rail 23, and the two test terminals 22 are located on the front wall of the base 21, so that they can be electrically contacted with the two pins of the capacitor product respectively, thereby completing the test. Workers can also easily observe the entire test process to avoid missed inspections of capacitor products.
[0024] like Figure 2 As shown, the test terminal 22 is composed of an inclined rod 221 and a horizontal rod 222 integrally connected to the inclined rod 221. The inclined rod 221 is arranged on the base 21. The length direction of the horizontal rod 222 is in the same direction as the guiding direction of the guide rail 23 and is arranged outside the guide rail 23. In this way, the horizontal rod 222 is perpendicular to the pin of the capacitor product, and the entire horizontal rod 222 can form an electrical contact with the pin, thereby ensuring the reliability of the electrical test.
[0025] like Figure 2 , Figure 3 , Figure 4 As shown, the inclined rods 221 of the two test terminals 22 are arranged in an inclined direction toward the material belt input direction, and the horizontal rods 222 on the two test terminals 22 are formed by bending the lower ends of the corresponding inclined rods 221 toward the material belt output direction. In this way, a feeding angle is formed between the inclined rods 221 and the material belt, thereby facilitating the entry of the material belt. When the material belt is moved along the Figure 3 When moving forward in the direction indicated by the middle arrow, the horizontal rod 222 contacts the pin and is lifted by the pin. The horizontal rod 222 drives the tilting rod 221 to elastically deform upward. The elastic force generated by the tilting rod 221 causes the horizontal rod 222 to press against the pin, forming a close contact with the pin, thereby ensuring a stable electrical contact between the horizontal rod 222 and the pin, thereby ensuring the accuracy of the test.
[0026] like Figure 2 , Figure 3 , Figure 4 As shown, the tilting rod and the horizontal rod are connected in a circular arc transition, so that when the pin contacts the horizontal rod 222, no collision occurs, which helps the material belt to move more smoothly on the guide rail 23, thereby making the test process smoother.
[0027] like Figure 2 , Figure 3 , Figure 4 As shown, a protrusion 211 is provided on the front wall of the base 21, and an inclined rod 221 of a test terminal 22 is connected to the base 21 through the protrusion 211. In this way, the two inclined rods 221 are arranged one after the other on the front wall of the base 21, which can prevent the two horizontal rods 222 from touching each other to form a short circuit, and further ensure the reliability of the test process.
[0028] like Figure 2 , Figure 3 As shown, the guide rail 23 is provided with a limiting guide groove 231, and the horizontal rod 222 of the test terminal 22 is placed outside the limiting guide groove 231. When the test device is working, the material strip is placed in the limiting guide groove 231, and the pin is placed outside the limiting guide groove 231. Due to the limiting and guiding function of the limiting guide groove 231, the position of the material strip can be prevented from being offset to affect the accuracy of the test.
[0029] like Figure 2 , Figure 3 As shown, the limiting guide groove 231 is opened horizontally through the top surface of the guide rail 23. In this way, the material strip moves along the top surface of the guide rail 23, the guide rail 23 can better support the material strip, and the limiting guide groove 231 can also play a more stable role in limiting and guiding the material strip, which is beneficial to the stability of the contact between the pin and the horizontal rod 222 of the test terminal 22, thereby further improving the accuracy of the test.
[0030] like Figure 2 , Figure 3 , Figure 4 As shown, the electrical test device 2 further includes a connecting plate 24, and the two ends of the connecting plate 24 are respectively connected to the rear wall of the base 21 and the rear wall of the guide rail 23. In this way, the base 21 and the guide rail 23 form an integrated structure through the connecting plate 24, which is conducive to the manufacture and assembly of the electrical test device and has low cost.
