Description

Technical Field

[0001] The utility model relates to the technical field of workpiece measurement, in particular to a detection device. Background Art

[0002] After production, workpieces are typically inspected for accuracy using a micrometer or complex image-capturing inspection tools. For example, the thickness of the raised structure on the inside of a mobile phone's midframe needs to be checked. However, direct micrometer inspection requires the operator to constantly adjust the probe's extension to accurately inspect the workpiece, resulting in low inspection efficiency. Complex image-capturing inspection tools offer high efficiency and accuracy, but come at a high cost. Utility Model Content

[0003] In view of the above situation, it is necessary to provide a detection device to improve detection efficiency at a low cost.

[0004] The present invention provides a detection device, including:

[0005] The detection assembly includes a guide member, a fixed member, a sliding member, a measuring member, a clamping member, and an elastic member. The guide member is connected to the fixed member, the sliding member is sleeved on the guide member and located above the fixed member, the sliding member is protruding with an abutment body, the measuring member is connected to the sliding member and has a retractable measuring body, the clamping member is movably inserted into the sliding member and connected to the measuring body, and the clamping member corresponds to the abutment body, and the two ends of the elastic member are elastically abutted against the sliding member and one end of the clamping member adjacent to the measuring body respectively;

[0006] The driving assembly includes a rotating member, a push cam and a driving cam. The rotating member is movably arranged through the sliding member and the guide member and is located above the fixed member. The push cam corresponds to the clamping member and is connected to one end of the rotating member. The driving cam is connected to the other end of the rotating member. The driving cam is used to drive the push cam to rotate synchronously under the action of external force, so that the clamping member and the abutment body move away from each other and compress the elastic member to receive the workpiece. The clamping member and the abutment body are used to clamp the opposite sides of the workpiece under the drive of the compressed elastic member, so that the measuring member can detect the workpiece based on the extended length of the measuring body.

[0007] When the above-mentioned detection device is in use, the driving cam first drives the push cam to rotate synchronously along the preset direction under the action of external force, and the driving cam is pressed against the fixed part so that the sliding part drives the abutting body and the measuring part to move away from the clamping part. At the same time, the push cam pushes the clamping part away from the abutting body and compresses the elastic part to the side of the sliding part close to the measuring body, so that there is a large enough movable space between the clamping part and the abutting body to receive the workpiece to be detected. Then, the area to be detected of the workpiece is moved between the clamping part and the abutting body. Finally, the driving cam rotates in the opposite direction of the preset direction under the action of external force, and the compressed elastic part provides elastic force to drive the abutting body and the clamping part to flexibly clamp the opposite sides of the workpiece. The measuring body connected to the clamping part moves synchronously, and the measuring part detects the thickness of the area to be detected of the workpiece based on the extended length of the measuring body, thereby quickly completing the detection of the workpiece, thereby improving the detection efficiency at a low cost.

[0040] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0041] See also Figure 1 The embodiment of the present application provides a detection device 100 for detecting a workpiece 200, comprising a detection component 10 and a drive component 20. The workpiece 200 may be a mobile phone middle frame, and the detection device 100 detects a protruding structure on the inner side of the mobile phone middle frame.

[0042] See also Figure 2 and Figure 3The detection assembly 10 includes a guide member 11, a fixed member 12, a sliding member 13, a measuring member 14, a clamping member 15, and an elastic member 16. The guide member 11 is connected to the fixed member 12. The sliding member 13 is sleeved on the guide member 11 and located above the fixed member 12. The sliding member 13 is provided with a protruding abutment 131. The measuring member 14 is connected to the sliding member 13 and has a retractable measuring body 141. The clamping member 15 is movably inserted into the sliding member 13 and connected to the measuring body 141. The clamping member 15 corresponds to the abutment 131. The two ends of the elastic member 16 elastically abut against the sliding member 13 and one end of the clamping member 15 adjacent to the measuring body 141, respectively. The driving assembly 20 includes a rotating member 21, a push cam 22, and a driving cam 23. The rotating member 21 is movably provided through the sliding member 13 and the guide member 11 and is located above the fixed member 12. The push cam 22 corresponds to the clamping member 15 and is connected to one end of the rotating member 21. The driving cam 23 is connected to the other end of the rotating member 21. The driving cam 23 is used to drive the push cam 22 to rotate synchronously under the action of an external force, so that the clamping member 15 and the abutting body 131 move away from each other and compress the elastic member 16 to receive the workpiece 200. The clamping member 15 and the abutting body 131 are used to clamp the workpiece 200 on opposite sides respectively under the drive of the compressed elastic member 16, so that the measuring member 14 can detect the workpiece 200 based on the extended length of the measuring body 141. By way of example, the elastic member 16 can be a spring, the measuring member 14 can be a dial gauge, and the measuring body 141 can be a detection probe of the dial gauge.

[0043] When the above-mentioned detection device 100 is in use, the cam 23 is first driven to drive the push cam 22 to rotate synchronously in a preset direction under the action of external force, and the driving cam 23 is pressed against the fixing member 12 so that the sliding member 13 drives the abutting body 131 and the measuring member 14 to move away from the clamping member 15. At the same time, the push cam 22 pushes the clamping member 15 away from the abutting body 131 and compresses the elastic member 16 to the side of the sliding member 13 close to the measuring body 141, so that there is a large enough movable space between the clamping member 15 and the abutting body 131 to receive the workpiece 200 to be detected. Then, the workpiece 200 is moved. The area to be inspected of the workpiece 200 is moved between the clamping member 15 and the abutment 131. Finally, the driving cam 23 is rotated in the opposite direction of the preset direction under the action of external force. The compressed elastic member 16 provides elastic force to drive the abutment 131 and the clamping member 15 to flexibly clamp the opposite sides of the workpiece 200. The measuring body 141 connected to the clamping member 15 moves synchronously. The measuring member 14 detects the thickness of the area to be inspected of the workpiece 200 based on the extended length of the measuring body 141, thereby quickly completing the inspection of the workpiece 200, thereby improving the inspection efficiency at a low cost.

[0044] See also Figure 3In some embodiments, the sliding member 13 further includes a sliding body 132 and a connecting body 133. The sliding body 132 is sleeved on the guide member 11 and rotatably connected to the rotating member 21. The sliding body 132 defines a receiving groove 1321 and a receiving groove 1322, which respectively receive the elastic member 16 and the abutting cam 22. The abutting body 131 is protruding from the side of the sliding body 132 facing away from the driving cam 23. One end of the sliding body 132 is connected to the measuring member 14. The connecting body 133 is connected to the other end of the sliding body 132 and defines a guide groove 1331. The guide groove 1331 is used to receive the end of the clamping member 15 away from the measuring member 141.

[0045] Thus, by arranging the rotating member 21, the measuring member 14, and the abutment member 131 at different positions on the sliding member 132, the detection assembly 10 and the drive assembly 20 can be rationally arranged, preventing interference between the various components during operation. Furthermore, the guide groove 1331 defined in the connecting member 133 receives the end of the clamping member 15 away from the measuring member 141, allowing the guide groove 1331 to guide the movement direction of the clamping member 15, thereby enabling precise relative movement of the abutment member 131 and the clamping member 15, thereby achieving accurate measurement of the workpiece 200.

[0046] See also Figure 2 and Figure 3 In some embodiments, the clamping member 15 includes a movable body 151, a supporting body 152, and a clamping body 153. One end of the movable body 151 is movably provided in the sliding body 134 and the elastic member 16 and is connected to the measuring body 141, and the other end of the movable body 151 is movably provided in the guide groove 1331. The supporting body 152 is located in the receiving groove 1321 and is connected to the movable body 151. The bottoms of the supporting body 152 and the receiving groove 1321 respectively abut against the two ends of the elastic member 16. The clamping body 153 is connected to the movable body 151, and one end of the clamping body 153 extends to the receiving groove 1322 and corresponds to the pushing cam 22. The other end of the clamping body 153 corresponds to the abutting body 131. The clamping body 153 is used to clamp the workpiece 200 with the abutting body 131.

[0047] In this way, the movable body 151 is movably inserted into the elastic member 16, so that the movable body 151 limits the elastic force direction of the elastic member 16, so that the elastic member 16 is always compressed or provides elastic force along the direction of the abutting body 152 pointing to the clamping body 153, thereby ensuring the stability of the clamping body 153 and the abutting body 131 in clamping the workpiece 200.

[0048] Please continue reading Figure 3 In some embodiments, the guide member 11 is provided with a avoidance hole 111 , which penetrates the guide member 11 along the direction from the push cam 22 to the driving cam 23 , and is used to accommodate the rotating member 21 .

[0049] In this way, the avoiding groove accommodates the rotating member 21, so that the avoiding hole 111 avoids the rotating member 21, thereby preventing interference between the rotating member 21 and the guide member 11 when the driving cam 23 drives the sliding member 13 to move away from the clamping member 15 through the rotating member 21.

[0050] See also Figure 2 and Figure 3 In some embodiments, the push cam 22 has a first push surface 221 and a second push surface 222 connected to each other, and the distance between the first push surface 221 and the axis of the rotating member 21 is greater than the distance between the second push surface 222 and the axis of the rotating member 21.

[0051] In this way, by setting the distance between the first pushing surface 221 and the axis of the rotating member 21 to be greater than the distance between the second pushing surface 222 and the axis of the rotating member 21, when the pushing cam 22 rotates along the preset direction, the pushing cam 22 pushes the clamping member 15 away from the abutting body 131 through the first pushing surface 221, and when the pushing cam 22 rotates in the opposite direction of the preset direction, the pushing cam 22 loosens the clamping member 15 through the second pushing surface 222, so that the clamping member 15 moves close to the abutting body 131 under the drive of the elastic member 16, thereby realizing the function of driving the clamping member 15 to move close to the abutting body 131 or away from the abutting body 131 by alternatingly corresponding to the clamping member 15 through the first pushing surface 221 and the second pushing surface 222.

[0052] See also Figure 3 In some embodiments, the driving cam 23 includes a cam body 231 and a handle 232. The cam body 231 is connected to the rotating member 21 and has a first pushing surface 2311 and a second pushing surface 2312 connected thereto. The distance between the first pushing surface 2311 and the axis of the rotating member 21 is greater than the distance between the second pushing surface 2312 and the axis of the rotating member 21. The handle 232 and the first pushing surface 2311 and the second pushing surface 2312 are sequentially arranged on the cam body 231 along the circumference of the cam body 231.

[0053] In this way, by setting the distance between the first pushing surface 2311 and the axis of the rotating member 21 to be greater than the distance between the second pushing surface 2312 and the axis of the rotating member 21, when the driving cam 23 rotates along the preset direction, the driving cam 23 abuts against the fixed member 12 through the first pushing surface 2311, so as to drive the rotating member 21 and the sliding member 13 to move away from the clamping member 15. When the driving cam 23 rotates in the opposite direction of the preset direction, the driving cam 23 loosens the fixed member 12 through the second pushing surface 2312, so that the sliding body 132 drives the abutting body 131 to move close to the clamping member 15 under the drive of the elastic member 16. In this way, the first pushing surface 2311 and the second pushing surface 2312 alternately correspond to the fixed member 12, thereby realizing the function of driving the sliding body 132 to move close to the clamping member 15 or away from the clamping member 15. In addition, by arranging the handle 232 and the first pushing surface 2311 and the second pushing surface 2312 in sequence on the cam body 231 along the circumference of the cam body 231, it is convenient for the operator to apply external force to the driving cam 23 and avoid the handle 232 interfering with the normal operation of the first pushing surface 2311 and the second pushing surface 2312.

[0054] See also Figure 2 In some embodiments, the detection assembly 10 further includes a supporting member 17 , which is disposed on one side of the sliding member 13 and connected to the sliding member 13 , and is used to support the handle 232 when the clamping member 15 and the abutting body 131 abut against each other.

[0055] In this way, after completing the inspection operation on a workpiece 200, the clamping body 153 and the abutting body 131 abut against each other to return the measuring body 141 to zero. At this time, the supporting member 17 supports the handle 232 so that the handle 232 is in the initial position, which makes it easier for the handle 232 to repeatedly drive the driving cam 23 and the pushing cam 22 to rotate along the preset direction.

[0056] See also Figure 3 In some embodiments, the detection assembly 10 further includes a stopper 18 , which is disposed on a side of the fixing member 12 away from the guide member 11 and is rotatably connected to the fixing member 12 , and is used to resist the handle 232 .

[0057] When the handle 232 drives the driving cam 23 and the pushing cam 22 to rotate in a preset direction and a preset angle, the distance between the clamping body 153 and the abutting body 131 is maximized so that the workpiece 200 can be stably moved between the clamping body 153 and the abutting body 131. In this way, the stop member 18 rotates toward the sliding member 13, so that the stop member 18 abuts against the side wall of the handle 232, preventing the handle 232 from driving the driving cam 23 and the pushing cam 22 to move in the opposite direction of the preset direction, thereby making the clamping body 153 and the abutting body 131 always maintain the maximum distance when the workpiece 200 moves between the two, thereby improving the detection stability.

[0058] See also Figure 1 and Figure 4 In some embodiments, the detection device 100 further includes a supporting assembly 30, which includes a supporting member 31, a positioning member 32, and a pressing member 33. The supporting member 31 is movably disposed on one side of the guide member 11 and is used to support the workpiece 200. The positioning member 32 is disposed on and connected to the supporting member 31, and is used to position the workpiece 200. The pressing member 33 is disposed on the supporting member 31 at a distance from the positioning member 32, and is used to press the workpiece 200 against the supporting member 31.

[0059] In this way, by setting the specific structure of the supporting component 30, the positioning member 32 can position the workpiece 200 to the supporting member 31 so that the workpiece 200 maintains the preset placement position and orientation, and the pressing member 33 presses the workpiece 200 to the supporting member 31 to fix the workpiece 200 to the supporting member 31, thereby preventing the workpiece 200 from detaching from the supporting member 31 or shaking when the supporting member 31 drives the workpiece 200 to move, thereby ensuring the stability of detection.

[0060] See also Figure 1 、 Figure 4 and Figure 5 In some embodiments, a sidewall of the carrier 31 is provided with a slide groove 311. The detection device 100 further includes a support assembly 40, which includes a support member 41, a slide rail 42, and a stopper 43. The support member 41 is connected to the guide member 11, and the slide rail 42 is disposed on the support member 41. The slide rail 42 is received in the slide groove 311 to guide the carrier 31 to move toward the abutment body 131. The stopper 43 is disposed between the slide rail 42 and the stopper 43 and is connected to the support member 41. The stopper 43 is configured to abut against the carrier 31.

[0061] In this way, the slide rail 42 is received in the slide groove 311, so that the slide rail 42 guides the movement direction of the carrier 31, so that the carrier 31 drives the workpiece 200 to move accurately close to the abutment body 131, thereby accurately moving the area to be inspected of the workpiece 200 between the abutment body 131 and the clamping body 153. In addition, by providing a limiter 43 between the slide rail 42 and the guide member 11, when the area to be inspected of the workpiece 200 moves between the abutment body 131 and the clamping body 153, the limiter 43 abuts against the carrier 31 to limit the carrier 31, so that the abutment body 131 and the clamping body 153 accurately clamp the area to be inspected of the workpiece 200, and prevent the clamping body 153 and the abutment body 131 from being misaligned with the area to be inspected of the workpiece 200.

[0062] In this embodiment, a plurality of slide grooves 311 are provided on the peripheral side of the carrier 31, and the slide rails 42 are accommodated by different slide grooves 311 so that different detection areas of the workpiece 200 can be moved between the clamping body 153 and the abutment body 131 respectively, thereby facilitating the detection device 100 to detect different detection areas of the workpiece 200.

[0063] The working process of the above-mentioned detection device 100 is roughly as follows:

[0064] First, the workpiece 200 is placed on the carrier 31 . The positioning member 32 positions the workpiece 200 so that the workpiece 200 maintains a preset placement position and orientation. The pressing member 33 presses the workpiece 200 against the carrier 31 to secure the workpiece 200 to the carrier 31 .

[0065] Then, the driving cam 23 drives the resisting cam 22 to rotate synchronously in a preset direction under the action of external force. The driving cam 23 abuts against the fixing member 12 so that the sliding member 13 drives the abutting body 131 and the measuring member 14 to move away from the clamping member 15. At the same time, the resisting cam 22 pushes the clamping member 15 away from the abutting body 131 and compresses the elastic member 16 to the bottom of the receiving groove 1321, so that there is a large enough movable space between the clamping member 15 and the abutting body 131 to receive the workpiece 200 to be inspected. The stop member 18 rotates toward the sliding member 13 so that the stop member 18 abuts against the side wall of the handle 232.

[0066] Next, the carrier 31 receives the slide rail 42 via the slide groove 311 , so that the carrier 31 moves closer to the abutment 131 under the guidance of the slide rail 42 . The stopper 43 abuts against the carrier 31 , so that the area to be inspected of the workpiece 200 moves between the clamping body 153 and the abutment 131 .

[0067] Finally, the driving cam 23 rotates in the opposite direction of the preset direction under the action of external force, and the compressed elastic member 16 provides elastic force to drive the abutment body 131 and the clamping body 153 to flexibly clamp the opposite sides of the workpiece 200, and the measuring body 141 connected to the clamping member 15 moves synchronously. The measuring member 14 detects the thickness of the area to be inspected of the workpiece 200 based on the extended length of the measuring body 141, thereby quickly completing the inspection of the workpiece 200, thereby improving the inspection efficiency at a low cost.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
