Description

Technical Field

[0001] This utility model relates to the field of product size measurement, and more particularly to a flash measuring instrument. Background Technology

[0002] Traditional dimensional measurement equipment consists of at least two devices: one for feature identification and the other for measuring. In current measurement processes, the design concepts of these two devices have no overlap.

[0003] In addition, the products (hardware parts, plastic parts, electronic components, etc.) are still transferred using a customized moving mechanism. This ensures that the products do not shift position when moving from one device to another.

[0004] In conclusion, for manufacturers, adding an extra mobile mechanism will increase the space occupied. Moreover, as mentioned above, having at least two devices will also increase the space occupied by this design. Utility Model Content

[0005] To address the aforementioned issues, this invention provides a flash meter that offers both feature verification and dimensional measurement functions. It occupies significantly less space than two separate devices used by manufacturers. Furthermore, the number of these devices can be increased, thereby enhancing overall production efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a flash detector, comprising a worktable, characterized in that the worktable is provided with:

[0007] A positioning component that contacts the side of a product, the positioning component having a shape that contacts multiple sides of the product;

[0008] The first linear motion mechanism has a pattern acquisition unit and a measurement unit on the same output end that provides dimensional changes, wherein the spatial layout of the pattern acquisition unit and the measurement unit remains constant.

[0009] The beneficial effects of this utility model are:

[0010] This invention constructs an environment suitable for product testing. First, the testing position and posture of the product are fixed by a positioning component. After being constrained, the position of the product coincides with the acquisition range of the pattern acquisition unit, eliminating the need for transfer by a moving mechanism and completely eliminating the risk of product displacement. The pattern acquisition unit and the measurement unit are set on the output end of the same first linear moving mechanism, which simultaneously meets the movement needs of both the pattern acquisition unit and the measurement unit. Based on the dual functions of the same device, the fixed spatial layout of the pattern acquisition unit and the measurement unit, by compensating the measurement unit with a fixed spacing, enables the measurement unit to accurately detect the dimensional parameters between features.

[0011] The aforementioned spacing refers to the distance between the pattern acquisition unit and the measurement unit. For example, if the distance between the central axes of the two execution units is 5cm, after the pattern acquisition unit detects the first feature, the first linear movement mechanism simultaneously drives the pattern acquisition unit and the measurement unit to translate by 5cm. At this time, the zero point of the measurement unit coincides with the feature. When the next feature is detected, following the method described above, after the measurement unit records the first feature, it will continuously record the distance between the measurement unit and the next feature, thereby completing the measurement of the distance between holes or the length of the product edge.

[0012] Preferably, the positioning component is an L-shaped positioning plate. The product is guided to adjust to the preset position direction by touching the inner side of the positioning plate, which is fixed in position.

[0013] In this specific embodiment, the first linear movement mechanism provides three-dimensional (X, Y, Z axis) coordinate changes, wherein the output end of the Z axis controls the longitudinal spatial changes of the pattern acquisition unit and the measurement unit, and can adaptively adjust the distance between the pattern acquisition unit, the measurement unit and the product when facing products with different thicknesses.

[0014] The preferred device for pattern acquisition is a camera, while the other measuring unit is an existing measuring device, such as a laser rangefinder.

[0015] This utility model is used in conjunction with operators who are responsible for placing the product onto the worktable. In order to reduce the subsequent calibration process, the worktable is set on the output end of the second linear moving mechanism. Preferably, the second linear moving mechanism is only a bidirectional reciprocating structure. Of course, it can also be designed as a multi-axis structure according to the customer to meet the needs of more reciprocating directions.

[0016] The specific testing principle of this utility model will be explained in detail below using a circuit board as an example:

[0017] S1, the second linear moving mechanism is controlled by computer to move the worktable away from the work position, so that the operator can put the circuit board on the worktable and correct the position of the circuit board by the positioning plate;

[0018] S2, the workbench resets and begins dimensional measurement. For example, if the current project is to measure the distance between two holes, the camera is used to take pictures of the circuit board first. The collected pattern data is output to the computer. The computer has a pre-set visual positioning feature comparison system. After the computer obtains the position of the first hole from the pattern data, the first linear movement mechanism readjusts the position of the laser rangefinder to confirm the position of the first hole. At the same time, the position of the camera will also change with the movement of the laser rangefinder to collect new pattern data from the new area of ​​the product.

[0019] Repeat the above steps. The computer can find the positions of the two holes. After confirming the position of the first hole, the laser rangefinder will record the distance it moves under the drive of the first linear movement mechanism, and stop recording when it reaches the position of the second hole.

[0020] Similarly, following the above method, the length of the side can be recorded, for example, by selecting the features at both ends of the side line using a computer. Attached Figure Description

[0027] like Figure 1-6 As shown, a flash detector includes a workbench 1, characterized in that the workbench 1 is equipped with:

[0028] Positioning member 2 that contacts the side of the product, the positioning member 2 having a shape that contacts multiple sides of the product;

[0029] The first linear movement mechanism 3 has a pattern acquisition unit 41 and a measurement unit 42 on the same output end that provides dimensional changes, wherein the spatial layout of the pattern acquisition unit 41 and the measurement unit 42 remains constant.

[0030] The beneficial effects of this utility model are:

[0031] This invention constructs an environment suitable for product testing. First, the positioning component 2 fixes the test position and posture of the product. After being constrained, the position of the product coincides with the acquisition range of the pattern acquisition unit 41, eliminating the need for transfer by the moving mechanism and completely eliminating the risk of product displacement. The pattern acquisition unit 41 and the measurement unit 42 are set on the output end of the same first linear moving mechanism 3, which simultaneously meets the movement requirements of the pattern acquisition unit 41 and the measurement unit 42. Based on the fact that the same device has two functions, the fixed spatial layout of the pattern acquisition unit 41 and the measurement unit 42, by compensating the measurement unit 42 with a fixed distance, enables the measurement unit 42 to accurately detect the dimensional parameters between features.

[0032] The aforementioned spacing refers to the distance between the pattern acquisition unit 41 and the measurement unit 42. For example, the spacing between the central axes of the two execution units is 5cm. After the pattern acquisition unit 41 detects the first feature, the first linear movement mechanism 3 simultaneously drives the pattern acquisition unit 41 and the measurement unit 42 to translate by 5cm. At this time, the zero point position of the measurement unit 42 coincides with the feature. When the next feature is detected, in accordance with the above method, after the measurement unit 42 records the first feature, it will continue to record the distance between the measurement unit 42 and the next feature, thereby completing the measurement of the distance between holes or the length of the product edge.

[0033] Preferably, the positioning component 2 is an L-shaped positioning plate. The product is guided to adjust to the preset position direction by touching the inner side of the positioning plate.

[0034] In this specific embodiment, the first linear movement mechanism 3 provides three-dimensional (X, Y, Z axis) coordinate changes, wherein the output end of the Z axis controls the longitudinal spatial changes of the pattern acquisition unit 41 and the measurement unit 42, and can adaptively adjust the distance between the pattern acquisition unit 41, the measurement unit 42 and the product when facing products with different thicknesses.

[0035] The pattern acquisition unit 41 is preferably a camera, while the other measurement unit 42 is an existing measuring device, such as a laser rangefinder.

[0036] This utility model is used in conjunction with operators. The operators are responsible for placing the product onto the worktable 1. At the same time, in order to reduce the subsequent calibration process, the worktable 1 is set on the output end of the second linear moving mechanism 5. Preferably, the second linear moving mechanism 5 is only a bidirectional reciprocating structure. Of course, it can also be designed as a multi-axis structure according to the customer to meet the needs of more reciprocating directions.

[0037] The specific testing principle of this utility model will be explained in detail below using a circuit board as an example:

[0038] S1, the second linear moving mechanism 5 is controlled by computer to move the worktable 1 away from the work position so that the operator can put the circuit board on the worktable 1 and correct the position of the circuit board by the positioning plate.

[0039] S2, Workbench 1 resets and begins dimensional measurement. For example, if the current project is to measure the distance between two holes, the circuit board is photographed first by the camera, and the collected pattern data is output to the computer. The computer has a pre-set visual positioning feature comparison system. After the computer obtains the position of the first hole from the pattern data, the first linear movement mechanism 3 readjusts the position of the laser rangefinder to confirm the position of the first hole. At the same time, the position of the camera will also change with the movement of the laser rangefinder to collect new pattern data from the new area of ​​the product.

[0040] Repeat the above steps. The computer can find the positions of the two holes. After confirming the position of the first hole, the laser rangefinder will record the distance it moves under the drive of the first linear movement mechanism 3, and the recording will stop when it reaches the position of the second hole.

[0041] Similarly, following the above method, the length of the side can be recorded, for example, by selecting the features at both ends of the side line using a computer.

[0042] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
