Detailed Implementation

[0029] The present invention will now be described in conjunction with specific embodiments.

[0030] Example 1, as Figures 1 to 3 As shown, a product positioning height detection fixture includes a fixture base plate 1 and a fixture top plate 2 located on the upper side of the fixture base plate 1. The upper surface of the fixture base plate 1 is provided with a product placement area 11, and the fixture top plate 2 is equipped with a plurality of detection components 3.

[0031] Among them, such as Figures 1 to 4As shown, the detection component 3 includes a detection base 31 installed on the lower surface of the fixture top plate 2. A fixed reference block 32 is installed at the lower end of the detection base 31. A reference contact portion 321 protruding downward is provided at the lower end of the fixed reference block 32. The reference contact portion 321 and the fixed reference block 32 are an integral structure.

[0032] Furthermore, such as Figure 3 and Figure 4 As shown, the fixed reference block 32 has a movable mounting hole 322 on the side of the reference contact portion 321. A movable detection element 33 is embedded in the movable mounting hole 322. The lower end of the movable detection element 33 extends to the lower end of the fixed reference block 32. A sensor mounting block 34 is screwed onto the upper end of the fixed reference block 32. A distance measuring sensor 35 is mounted on the sensor mounting block 34 located directly above the movable detection element 33.

[0033] It needs to be explained that, such as Figures 1 to 3 As shown, a number of product positioning blocks 4 are installed on the upper surface of the fixture base plate 1 around the product placement area 11; when the product 100 is placed in the product placement area 11 of the fixture base plate 1, the number of product positioning blocks 4 cooperate to achieve accurate positioning of the product 100.

[0034] It should be noted that the product positioning height detection fixture of this embodiment is applied to the corresponding detection device. The detection device has a support structure, the fixture base plate 1 is fixedly installed on the support, and the support structure is equipped with a drive component for driving the top plate 2 of the fixture to move up and down. The drive component can be a cylinder or a linear drive module. In addition, the support structure is also equipped with an alarm light and a controller. The alarm light, the drive component and each ranging sensor 35 of this embodiment are electrically connected to the controller.

[0035] The following is a detailed description of the product positioning height detection fixture in Embodiment 1, using a specific working process as an example:

[0036] Step a: Place product 100 in product placement area 11 of fixture base plate 1, and position product 100 by several product positioning blocks 4 to ensure that product 100 is accurately positioned in product placement area 11 of fixture base plate 1.

[0037] Step b: Start the drive unit and drive the fixture top plate 2 to move down. During this process, the fixture top plate 2 drives each detection component 3 to move down synchronously. When the fixture top plate 2 moves down to the position and the product positioning height detection fixture is closed, the fixed reference block 32 of each detection component 3 presses against the corresponding reference position of the product 100 through the corresponding reference contact part 321, and each movable detection component 33 is aligned with the corresponding positioning protrusion position.

[0038] When the active detection element 33 contacts the corresponding positioning protrusion, it indicates that product 100 is an NG product. At this time, the reaction of the positioning protrusion will cause the active detection element 33 to move upward. The distance sensor 35 senses the position change of the active detection element 33 and feeds the signal back to the controller. The controller controls the alarm light to turn red.

[0039] When the moving detection element does not contact the corresponding positioning protrusion, it indicates that product 100 is OK. At this time, the moving detection element 33 does not move upward relative to the fixed reference block 32, and the controller controls the alarm light to turn green.

[0040] Step c: After product 100 has been inspected, the drive unit drives the top plate 2 of the fixture to move upward and reset, and the staff removes the inspected product 100 from the bottom plate 1 of the fixture.

[0041] It should be emphasized that the product positioning height detection fixture of this embodiment can effectively detect the height of multiple positioning protrusions of the product 100. During detection, the fixed reference block 32 contacts and presses against the reference position of the product 100, and then the height of the corresponding positioning protrusion is determined according to the position of the movable detection element 33 relative to the fixed reference block 32. Compared with the prior art, the product positioning height detection fixture of this embodiment has the advantages of novel structural design and high detection effect.

[0042] Example 2, as Figure 4 As shown, the difference between this embodiment 2 and embodiment 1 is that: the inner wall of the movable mounting hole 322 is provided with an anti-detachment shoulder 323, and the upper end of the movable detection member 33 is provided with a detection member shoulder 331 located above the anti-detachment shoulder 323.

[0043] When the movable detection element 33 moves down to the lower limit position relative to the fixed reference block 32, the detection pin shoulder of the movable detection element 33 abuts against the anti-disengagement shoulder 323; through the cooperation between the detection element shoulder 331 and the anti-disengagement shoulder 323 of the fixed reference block 32, this embodiment can effectively prevent the movable detection element 33 from retracting downward from the movable mounting hole 322 of the fixed reference block 32.

[0044] Example 3, as Figure 1 and Figure 2 As shown, the difference between this embodiment 3 and embodiment 1 is that: the left and right ends of the fixture top plate 2 are respectively equipped with vertically arranged guide posts 51, the lower ends of each guide post 51 extend to the lower end side of the fixture top plate 2, and the left and right ends of the fixture bottom plate 1 are respectively equipped with guide sleeves 52 corresponding to the guide posts 51 on the corresponding sides.

[0045] When the product positioning height detection fixture is in the closed state, the lower end of each guide post 51 is inserted into the center hole of the corresponding guide sleeve 52.

[0046] During the closing process of the product positioning height detection fixture in this embodiment three, the guide post 51 and the guide sleeve 52 cooperate to ensure the accuracy of the closing action.

[0047] Example 4, as Figures 1 to 4 As shown, the difference between this embodiment four and embodiment one is that the detection base 31 includes a base fixing member 311 and a base movable member 312 installed on the base fixing member 311 via a guide rail slider pair 313. The base fixing member 311 is screwed and fastened to the lower surface of the fixture top plate 2, and the fixing reference block 32 is screwed and fastened to the lower end of the base movable member 312.

[0048] An elastic element 314 is installed between the movable base part 312 and the top plate of the fixture. The upper end of the elastic element 314 abuts against the top plate of the fixture, and the lower end of the elastic element 314 abuts against the upper end of the movable base part 312.

[0049] To prevent the movable base component 312 from retracting from the fixed base component 311, this embodiment four adopts the following anti-detachment structure design: the fixed base component 311 is screwed with a lower stop bar 315, and the movable base component 312 is screwed with an upper stop bar 316. The upper stop bar 316 and the lower stop bar 315 are vertically aligned; when the movable base component 312 moves down relative to the fixed base component 311 to the lower limit position, the upper stop bar 316 abuts against the lower stop bar 315.

[0050] During the closing process of the product positioning height detection fixture in this embodiment four, the elastic force of the elastic element 314 causes the fixed reference block 32 to elastically press against the product 100 located in the product placement area 11, so as to ensure that the fixed reference block 32 can stably contact the corresponding reference position of the product 100, thereby ensuring the accuracy of the detection reference.

[0051] Example 5, as Figure 1 and Figure 2 As shown, the difference between this fifth embodiment and the fourth embodiment is that the top plate 2 of the fixture is equipped with a number of vertically arranged limiting posts 6, and the lower end of each limiting post 6 extends to the lower end side of the top plate 2 of the fixture.

[0052] When the product positioning height detection fixture is in the closed state, the lower end face of each limiting post 6 abuts against the upper surface of the fixture base plate 1.

[0053] It should be noted that the limiting post 6 in this embodiment 5 can effectively prevent the top plate 2 of the fixture from moving down excessively.

[0054] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
