Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to a relative position measuring device. Background Technology

[0002] The function of a solar inverter is to convert the direct current generated by solar panels into alternating current used by household appliances.

[0003] In related technologies, during the assembly process, if the heights of several contact terminals on a solar inverter are not uniform, during wiring, terminals that are too low may not make sufficient contact with the cable connector, leading to increased contact resistance; terminals that are too high may be excessively squeezed, causing deformation of the terminal or cable connector. Therefore, there is an urgent need for a device that can detect the height of the contact terminals. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a relative position measuring device that can detect the height of the contact terminals of a solar inverter and ensure that the height of each contact terminal is uniform.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] The first aspect of this application provides a relative position measuring device, comprising: a detection component including a horizontal drive member, a test head, a sliding member, and a first motor, wherein the test head is disposed on the sliding member, the first motor is connected to the sliding member, and the sliding member is disposed on the horizontal drive member; and a positioning component including a base and a clamp, wherein the clamp is disposed on the base, the first motor is used to drive the test head to move toward the clamp, and the clamp is used to place a solar inverter.

[0007] The sliding component includes a mounting base, a first guide rail, and a movable base. A first motor is mounted on the mounting base, the first guide rail is mounted on the mounting base, the movable base is mounted on the first guide rail, and the test head is mounted on the movable base. The first motor is used to drive the movable base, thereby driving the test head to move towards the fixture.

[0008] The horizontal drive component includes a second guide rail and a second motor, with the second motor mounted on the second guide rail and the mounting base mounted on the second guide rail.

[0009] The fixture has a limiting groove.

[0010] The positioning component also includes a cylinder, a pressure block, and a rubber block. The cylinder is mounted on the base, the pressure block is mounted on the cylinder, and the rubber block is mounted on the pressure block.

[0011] The clamp also has a hollow opening.

[0012] The positioning component includes a plurality of bases, and each base is provided with a gap.

[0013] The positioning component includes a plurality of clamps, the number of which is the same as the number of bases.

[0014] It also includes a chassis, which is located above the base.

[0015] It also includes a button located on one side of the base.

[0016] Compared with the prior art, the present invention has at least the following advantages:

[0017] In this application, the first motor drives the test head to move towards the solar inverter located on the fixture. After testing one of the contact terminals, the horizontal drive component drives the sliding component to move to the next contact terminal for testing. The information detected by the test head clearly determines whether each contact terminal is at the same height, avoiding the risks caused by inconsistent contact terminal heights.

[0021] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

[0022] It should be understood that although the terms "first," "second," "third," etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0023] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0024] The function of a solar inverter is to convert the direct current (DC) generated by solar panels into alternating current (AC) for household appliances. During assembly, if the height of several contact terminals on the solar inverter is inconsistent, terminals that are too low may not make sufficient contact with the cable connector, leading to increased contact resistance; terminals that are too high may be excessively compressed, causing deformation of the terminal or cable connector. Therefore, there is an urgent need for a device that can detect the height of the contact terminals.

[0025] To address the aforementioned issues, this application provides a relative position measuring device capable of detecting the height of the contact terminals of a solar inverter, ensuring that the height of each contact terminal is uniform.

[0026] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0027] See Figure 1 A relative position measuring device includes: a detection component 100 and a positioning component 200. The detection component 100 includes a horizontal drive component 110, a test head 120, a sliding component 130, and a first motor 140. The test head 120 is disposed on the sliding component 130, and the first motor 140 is connected to the sliding component 130. The sliding component 130 is disposed on the horizontal drive component 110. The positioning component 200 includes a base 210 and a clamp 220. The clamp 220 is disposed on the base 210. The first motor 140 is used to drive the test head 120 to move towards the clamp 220. The clamp 220 is used to place a solar inverter.

[0028] It should be noted that the test head 120 is a grating micrometer. The first motor 140 drives the grating micrometer to move towards the contact terminals of the solar inverter located on the fixture 220, so that the probe of the grating micrometer extends into the contact terminals, thereby obtaining the displacement. After the current contact terminal is tested, the first motor 140 drives the test head 120 located on the sliding member 130 to move away from the fixture 220. Then, the horizontal drive member 110 moves the sliding member 130 to the front of the next contact terminal, and the above testing operation is repeated. In this way, this application uses an automated method to clearly determine whether each contact terminal is at a uniform height by using the information detected by the test head 120. This not only provides high detection accuracy but also avoids the risks caused by inconsistent contact terminal heights.

[0029] See Figure 1 In one embodiment, the sliding member 130 includes a mounting base 131, a first guide rail 132, and a movable base 133. A first motor 140 is mounted on the mounting base 131, the first guide rail 132 is mounted on the mounting base 131, the movable base 133 is mounted on the first guide rail 132, and the test head 120 is mounted on the movable base 133. The first motor 140 is used to drive the movable base 133, thereby driving the test head 120 to move towards the fixture 220.

[0030] It should be noted that the first motor 140 drives the moving seat 133, which in turn drives the test head 120 to reciprocate in the direction of approaching or moving away from the fixture 220.

[0031] See Figure 1 In one embodiment, the horizontal drive member 110 includes a second guide rail 111 and a second motor 112, the second motor 112 being disposed on the second guide rail 111 and the mounting base 131 being disposed on the second guide rail 111.

[0032] It should be noted that the second motor 112 is used to drive the mounting base 131 to reciprocate on the second guide rail 111.

[0033] See Figure 2 In one embodiment, a limiting groove 221 is provided on the clamp 220. It can be understood that the limiting groove 221 on the clamp 220 is used to lock and limit the solar inverter.

[0034] See Figure 2 In one embodiment, the positioning component 200 further includes a cylinder 230, a pressure block 240, and a rubber block 250. The cylinder 230 is disposed on the base 210, the pressure block 240 is disposed on the cylinder 230, and the rubber block 250 is disposed on the pressure block 240.

[0035] Understandably, to prevent slight displacement of the solar inverter when the test head 120 extends into the contact terminal, the cylinder 230 drives the pressure block 240 to limit the solar inverter, making it more stably fixed on the clamp 220. At the same time, the rubber block 250 acts as a buffer to prevent scratches on the solar inverter.

[0036] See Figure 2 In one embodiment, the clamp 220 is also provided with a hollow opening 222.

[0037] It should be noted that the cutout 222 allows for easy access to the solar inverter.

[0038] See Figure 2 In one embodiment, the positioning component 200 includes a plurality of bases 210, with intervals provided between each base 210. Specifically, the positioning component 200 includes a plurality of clamps 220, the number of clamps 220 being the same as the number of bases 210.

[0039] It should be noted that, in order to improve efficiency, this application is equipped with two bases 210 and two clamps 220.

[0040] See Figure 2 In one embodiment, the relative position measuring device further includes a housing 300, which is located above the base 210.

[0041] It should be noted that the rear display screen on the chassis 300 can display the data detected by the test head 120 for easy viewing.

[0042] See Figure 2 In one embodiment, the relative position measuring device further includes a button 400, which is located on one side of the base 210. It should be noted that this button 400 is a start button, used to start the operation of the first motor 140 and the second motor 112.
