Description

Technical Field

[0001] The utility model relates to the field of detection devices, in particular to a shrapnel height detection device. Background Technique

[0002] As Figure 1 and Figure 2 shown, an automotive main control board generally includes a plastic part and a metal sheet. The metal sheet is fixedly connected to the bottom wall of the plastic part. A plurality of shrapnel are provided on both the front and back sides of the metal sheet, and the plurality of shrapnel protrude from the bottom wall and the top wall of the plastic part respectively. The height of the shrapnel is crucial. Before shipment, it is usually necessary to detect whether the height of the shrapnel meets the design requirements.

[0003] In the existing detection method, the height of the shrapnel is generally measured directly with a ruler. However, since the shrapnel is elastic, its height is likely to change during the detection process, resulting in inaccurate measurement results. Moreover, since there are a large number of shrapnel, measuring them one by one takes a lot of time, which is not conducive to improving work efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a shrapnel height detection device that can quickly detect whether the height of the shrapnel meets the design requirements.

[0005] To achieve the above purpose, a shrapnel height detection device provided by the utility model includes a main body, an upper cover, and a power-on detection module. A workpiece placement position for placing a workpiece is provided on the main body. A first conductive member, a second conductive member, a positioning member, and a plurality of support columns are provided in the workpiece placement position. In the vertical direction, the positioning member is higher than the support columns. The upper cover is detachably provided on the main body, and a third conductive member is provided on the upper cover. The power-on detection module includes a power supply module and at least two detection lights. Two ends of the power supply module are respectively electrically connected to the first conductive member and the second conductive member to form a first detection circuit. Two ends of the power supply module are also respectively electrically connected to the first conductive member and the third conductive member to form a second detection circuit. The two detection lights are respectively connected in series in the first detection circuit and the second detection circuit.

[0006] As can be seen from the above solution, by providing the first conductive member for electrically connecting with the metal sheet of the workpiece, the entire metal sheet is charged, which is convenient for transmitting electricity to each shrapnel; by providing the second conductive member for contacting the shrapnel on the bottom surface of the metal sheet, a conductive path is formed in the first detection circuit. If the detection light on the first detection circuit lights up, it means that the height of the shrapnel corresponding to the second conductive member meets the design requirements; by providing the third conductive member for contacting the shrapnel on the top surface of the metal sheet, a conductive path is formed in the second detection circuit. If the detection light on the second detection circuit lights up, it means that the height of the shrapnel corresponding to the third conductive member meets the design requirements. The utility model can simultaneously detect the heights of the shrapnel on both the front and back sides of the workpiece, and has the advantages of high work efficiency and high detection result accuracy.

[0007] A further solution is that the workpiece includes a plastic part and a metal sheet fixedly connected to the plastic part. The metal sheet is provided with at least two elastic pieces, and the two elastic pieces protrude from the bottom wall and the top wall of the plastic part respectively. The first conductive part is electrically connected to the metal sheet, and the two elastic pieces are electrically connected to the second conductive part and the third conductive part respectively.

[0008] A further solution is that there are multiple second conductive parts, third conductive parts and detection lights. Each second conductive part corresponds to a first detection circuit, and the first detection circuits are arranged in parallel. Each first detection circuit is provided with a detection light. Each third conductive part corresponds to a second detection circuit, and the second detection circuits are arranged in parallel. Each second detection circuit is provided with a detection light.

[0009] As can be seen from the above solution, by providing multiple second conductive parts and multiple third conductive parts, which are arranged in one-to-one correspondence with the respective elastic pieces on the metal sheet, and each elastic piece corresponds to a detection light, it is convenient to simultaneously detect the heights of all the elastic pieces, which is beneficial to improving work efficiency.

[0010] A further solution is that all the detection lights in all the first detection circuits are arranged on the main body and exposed outside the upper cover; all the detection lights in all the second detection circuits are arranged on the upper cover.

[0011] A further solution is that the first conductive part includes a contact head, an elastic part and a sleeve. One end of the contact head is embedded in the sleeve, the elastic part is arranged in the sleeve and elastically abuts against the contact head, and the contact head can telescopically move relative to the sleeve.

[0012] As can be seen from the above solution, by providing a telescopic contact head, it is ensured that the contact head can fully contact the metal sheet, and the workpiece will not be pushed up, avoiding affecting the normal contact between the elastic piece and the first conductive part and ensuring the detection accuracy.

[0013] A further solution is that the positioning part includes a limiting block. The number of limiting blocks is set to at least two. The two limiting blocks are respectively arranged on two adjacent sides of the workpiece placement position. The limiting block is provided with a stop surface and a guiding inclined surface on the side facing the workpiece placement position. The guiding inclined surface is arranged above the stop surface and extends towards the stop surface.

[0014] A further solution is that the positioning part includes positioning columns. The number of positioning columns is set to two. The two positioning columns are respectively arranged at both ends of the workpiece placement position. The upper part of the positioning column is provided with a tip.

[0015] A further solution is that the fixed end of the upper cover is hinged to the main body, and the free end of the upper cover can rotate around the fixed end; a quick-clamping component is arranged on the main body, and the quick-clamping component can press the free end towards the main body.

[0016] A further solution is that a pressing column is provided on the bottom wall of the upper cover, and the height by which the pressing column protrudes from the bottom plate of the upper cover is greater than the height by which the third conductive member protrudes from the bottom wall of the upper cover.

[0017] A further solution is that an indicator light detection component is provided on one side of the main body, a through hole is provided on the upper cover corresponding to the indicator light detection component, and the indicator light detection component includes a light-emitting light source that emits light upward.

[0018] As can be seen from the above solution, by providing the indicator light detection component, it is possible to detect whether the indicator light on the workpiece can work properly while detecting the height of the detection elastic piece. Description of the Drawings

[0029] A workpiece placement position matching the workpiece 1 is arranged on the top wall of the main body 2.

[0030] The upper cover 3 is detachably arranged on the main body 2. The upper cover 3 can be hinged to the main body 2, or the upper cover 3 is completely separated from the main body 2 and directly covered on the main body 2 when needed. In this embodiment, the former is preferred. Specifically, the fixed end of the upper cover 3 is hinged to the main body 2 through two hinges, and the free end of the upper cover 3 can rotate around the fixed end to cover directly above the main body 2. A quick-clamping assembly 25 is arranged on one side of the main body 2. When the upper cover 3 covers directly above the main body 2, the quick-clamping assembly 25 can press the free end of the upper cover 3 towards the main body 2 to ensure that the upper cover 3 can be fixed directly above the main body 2. The quick-clamping assembly 25 is a commonly used component in the art, and its detailed structure will not be described here.

[0031] A plurality of third conductive parts 31 are arranged on the upper cover 3, and the third conductive parts 31 are arranged in one-to-one correspondence with and electrically connected to the shrapnel 121 on the top wall of the workpiece 1.

A detection lamp 4 is connected in series in each first detection circuit and each second detection circuit.

[0033] The first detection circuit is used to detect the height of the elastic piece 121 on one side of the bottom wall of the workpiece 1. If the detection lamp 4 in the first detection circuit is lit, it means that the elastic piece 121 is in contact with the second conductive part 22 in the first detection circuit, making the first detection circuit conductive, that is, the height of the elastic piece 121 meets the design requirements.

[0034] The second detection circuit is used to detect the height of the elastic piece 121 on one side of the top wall of the workpiece 1. If the detection lamp 4 in the second detection circuit is lit, it means that the elastic piece 121 is in contact with the third conductive part 31 in the second detection circuit, making the second detection circuit conductive, that is, the height of the elastic piece 121 meets the design requirements.

[0035] To facilitate the visual observation of the lighting condition of the detection lamp 4 by the detection personnel, in this embodiment, all the detection lamps 4 in the first detection circuit are arranged on the main body 2 and exposed outside the upper cover 3; all the detection lamps 4 in the second detection circuit are arranged on the upper cover 3.

When the workpiece 1 is placed at the workpiece placement position, the metal piece 12 abuts against the contact head and pushes the contact head downward to ensure full contact between the metal piece 12 and the contact head.

[0037] To ensure that both the second conductive part 22 and the third conductive part 31 can accurately face the corresponding elastic pieces 121, the positioning member 23 in this embodiment includes three limit blocks 231 and two positioning posts 232. Specifically:

[0038] Two of the limit blocks 231 are arranged on the long side of the workpiece placement position, and the other limit block 231 is arranged on the short side of the workpiece placement position. The three limit blocks 231 limit the workpiece 1 from adjacent sides of the workpiece 1 to improve the position accuracy of the workpiece 1.

The four pressing posts 32 respectively correspond to four different parts of the workpiece placement position, facilitating pressing the workpiece 1 downward from four different parts respectively. The height by which the pressing posts 32 protrude from the bottom wall of the upper cover 3 is greater than the height by which the third conductive member 31 protrudes from the bottom wall of the upper cover 3, so that the pressing posts 32 first press the workpiece 1 downward, and then the third conductive member 31 contacts the elastic piece 121.

[0041] Combined with Figure 3 and Figure 4 , an indicator light detection component 5 is provided on one side of the top wall of the main body 2. The indicator light detection component 5 is arranged in correspondence with each indicator light housing 113 on the workpiece 1. The upper cover 3 is provided with a through hole 33 corresponding to the indicator light detection component 5, and the through hole 33 penetrates the thickness direction of the upper cover 3.
