Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0021] In this specification, the sensor device is prior art, and the step difference measuring device 6 is the Keyence GT2-A32 high-precision contact digital sensor. Example 1

[0022] like Figure 1 and Figure 2 As shown, the step difference measurement device includes a cabinet 1, and also includes: Marble slab 2 divides the internal space of equipment cabinet 1 into upper and lower spaces; Product positioning fixture 3 is a negative pressure adsorption type product positioning fixture, and product positioning fixture 3 is fixed to the upper surface of marble slab 2 and located in the upper space; further, product positioning fixture 3 is fixed to the upper surface of marble slab 2 by means of overhead bracket 7.

[0023] The drive module 4 is located on the upper surface of the marble slab 2 and moves in multiple directions in a plane perpendicular to the vertical axis Z, and the drive module 4 surrounds the periphery of the product positioning fixture 3. The cantilever bracket 5 has one end fixed to the top of the drive module 4 via a detachable structure, and the other end of the cantilever bracket 5 is free and extends above the top of the product positioning fixture 3 during measurement. The cantilever bracket 5 includes a fixed base plate 52, on which two symmetrically distributed L-shaped blocks 53 are mounted, and a cantilever plate 54 is mounted on the vertical part of the L-shaped blocks 53. The cantilever plate 54 and the fixed base plate 52 are staggered vertically, and when viewed from above, the cantilever plate 54 and the fixed base plate 52 are vertically distributed, together forming a highly rigid and stable support frame.

[0024] The step difference measuring device 6 is connected to the free end of the cantilever bracket 5 via a vertical position adjustment structure. The step difference measuring device 6 can be precisely adjusted in height via the vertical position adjustment structure to meet the measurement needs of different products.

[0025] During the measurement process, the drive module 4 moves in multiple directions within the horizontal plane according to a preset program, driving the cantilever bracket 5 and its end-mounted step difference measuring device 6 to measure the product surface on the product positioning fixture 3. In this embodiment, the step difference measuring device 6 uses a contact sensor, which can quickly detect height differences on the product surface and transmit the data to the control system in real time.

[0026] Specifically, such as Figure 4 , Figure 8 and Figure 9 As shown, the vertical position adjustment structure includes a clamp 81 that holds the step difference measuring device 6, and the clamp 81 slides with the cantilever bracket 5 through a vertical sliding block 82. The vertical sliding block 82 is provided with a plurality of strip holes 821 arranged along the vertical direction. At least one fastener 83 is inserted through the strip holes 821. The fastener 83 and the cantilever bracket 5 are threadedly connected. A sliding fit surface 1 822 is provided on at least one side of the vertical sliding block 82, and a sliding fit surface 2 823 that matches the sliding fit surface 1 822 is provided on the free end side of the cantilever bracket 5.

[0027] Meanwhile, a sliding fit protrusion 824 is provided on at least one side of the vertical sliding block 82, and a sliding fit surface 822 is provided on the inner side of the sliding fit protrusion 824. A notch 51 is provided on one side of the free end of the cantilever bracket 5, and one surface of the notch 51 is a sliding fit surface 823. The sliding fit protrusion 824 extends into the notch 51.

[0028] With the above structure, the step difference measuring device 6 and its holder 81 can slide smoothly in the vertical direction along the guide surface formed by the sliding fit surface 822 and the sliding fit surface 823. When coarse height adjustment is required, the operator can loosen the fastener 83 passing through the slot 821, thereby releasing the locking force between the vertical sliding block 82 and the cantilever bracket 5; at this time, the entire vertical position adjustment structure, together with the step difference measuring device 6, can be moved up and down as a whole, thereby quickly positioning it to a suitable approximate height range. The sliding fit protrusion 824 is embedded in the notch 51 at the free end of the cantilever bracket 5, which not only provides precise sliding guidance, but also effectively prevents the entire adjustment structure from lateral displacement or torsion during the adjustment process, ensuring the stability and straightness of the movement.

[0029] After coarse adjustment and determination of the target position, the operator can tighten the fastener 83 again. Because the slot 821 provides continuous adjustment space, the clamp 81 can be locked at any position within its vertical stroke, not just a limited number of fixed points, enhancing the flexibility and accuracy of adjustment. The end of the fastener 83 presses against the vertical sliding block 82, and friction is generated through the tight fit between the sliding mating surface 1 822 and the sliding mating surface 2 823, thus firmly locking the step difference measuring device 6 in the preset vertical measurement position, effectively preventing slight sinking or shaking that may occur during contact measurement due to the force applied to the probe.

[0030] like Figure 6 As shown, the vertical sliding block 82 and the sliding engagement protrusion 824 are vertically connected. Furthermore, in the vertical Z-axis direction, the length of the sliding engagement surface 822 is longer than the length of the sliding engagement surface 823. This vertical connection structure allows the vertical sliding block 82 and the sliding engagement protrusion 824 to form a stable "L"-shaped support, greatly enhancing the bending stiffness and stability of the entire vertical position adjustment structure when subjected to lateral forces from the step measuring device 6. Specifically, in the vertical Z-axis direction, the length of the sliding engagement surface 822 is designed to be significantly longer than the length of the sliding engagement surface 823, effectively preventing tilting or swaying caused by unstable guidance.

[0031] In addition, such as Figure 6 As shown, the drive module 4 includes an X-axis guide rail / lead screw pair 41 and a Y-axis guide rail / lead screw pair 42 fixed on the X-axis guide rail / lead screw pair 41. The fixed base plate 52 is fixed to the top of the Y-axis guide rail / lead screw pair 42 by a detachable structure. The X-axis guide rail / lead screw pair 41 is responsible for performing longitudinal movement, while the Y-axis guide rail / lead screw pair 42 can be adjusted laterally based on the X-axis movement.

[0032] Specifically, the operator places 6 product pieces into the conformal fixture plate 32 of the equipment, presses the start button, and the module will use the step difference measuring device 6 (Keyence - high precision contact digital sensor) to detect the step difference points of the products. After the equipment stops after the detection of 6 products is completed, the operator unloads the products. Example 2

[0033] The structure and principle of this embodiment are basically the same as those of Embodiment 1. The difference lies in that, for the step difference measuring device of Embodiment 1, this embodiment describes other components of the step difference measuring device.

[0034] like Figure 1 The equipment cabinet 1 is equipped with a lighting lamp 15 located on top of the product positioning fixture 3; the lighting lamp 15 provides sufficient and uniform illumination for the operation and measurement process, ensuring that the operator can clearly observe the product clamping situation, and assisting the step difference measuring instrument 6 in performing accurate positioning and measurement.

[0035] The product positioning fixture 3 includes a base plate 31 with several vacuum adsorption chambers. A contouring fixture plate 32 is provided on the base plate 31. Several adsorption positioning holes 321, each of which is connected to a vacuum adsorption chamber, are located on the contouring fixture plate 32. Each vacuum adsorption chamber is connected to a vacuum source. When the vacuum source is activated, each vacuum adsorption chamber works independently or in parallel. Through the adsorption positioning holes 321, a strong adsorption force is generated to firmly and accurately position and press the product onto the surface of the fixture, effectively avoiding any slight displacement of the product that may occur during the measurement process.

[0036] The drive module 4 is connected to the power supply terminal in the lower space via a conductive wire 43 that passes through the marble slab 2; Each corner of the bottom of the equipment cabinet 1 is provided with a pulley 11 and an adjustable support foot 12; The bottom surface of the equipment cabinet 1 is also provided with a radiator 13 and / or ventilation holes 14 that connect the lower space to the outside.

[0037] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
