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

Referring to fig. 1 and 2, some embodiments of the present application provide a detection apparatus 100. The detection device 100 is used for detecting a workpiece 200 such as a mobile phone frame or other electronic product frames.

Referring to fig. 1 and 2, the inspection apparatus 100 includes a workpiece pressing mechanism 300, and the workpiece pressing mechanism 300 includes an abutment plate 10, a pressing plate 20, an elastic assembly 30, a measurement platform 40, and a handle 50. In the present embodiment, the abutment plate 10 stands on the measuring platform 40, the abutment plate 10 has supporting convex steps 11 and elastic protrusions 12 arranged at intervals, and the abutment plate 10 is used for supporting the workpiece 200. The handle 50 and the compacting plates 20 are respectively connected to two ends of the elastic assembly 30. The elastic component 30 is disposed on the abutment plate 10, and the elastic component 30 passes through the abutment plate 10 to be connected with the pressing plate 20, and a receiving gap 21 for receiving the workpiece 200 is formed between the pressing plate 20 and the abutment plate 10. One end of the workpiece 200 is erected on the supporting convex step 11, the other end of the workpiece 200 is placed in the accommodating gap 21, the side surface of the workpiece 200 is abutted with the elastic bulge 12, when the workpiece 200 is placed in the accommodating gap 21, the pressing plate 20 is elastically abutted with the workpiece 200 under the action of the elastic assembly 30, and the workpiece 200 is pressed on the elastic bulge 12, so that the fixing of the workpiece 200 is realized. Since the pressing plate 20 is elastically abutted against the workpiece 200, crushing of the workpiece 200 can be avoided.

The elastic protrusions 12 may be silica gel protrusions or rubber protrusions.

Thus, when fixing the workpiece 200, the operator only needs to place the workpiece 200 in the accommodating gap 21, the pressing plate 20 abuts against the surface of the workpiece 200 under the action of the elastic component 30, and presses the workpiece 200 against the elastic protrusion 12, so that the workpiece 200 is fixed; when the fixing is released, the operator only needs to pull the pressing plate 20 to separate the pressing plate 20 from the workpiece 200, and at this time, the workpiece 200 can be taken out. Because the workpiece 200 is directly clamped on the workpiece pressing mechanism 300, the workpiece 200 does not need to be mounted on a clamping jig, so that the clamping efficiency of the workpiece 200 is improved, and in addition, the clamping and dismounting operations of the workpiece 200 are simple, thereby being beneficial to improving the efficiency of detecting the workpiece 200.

Referring to fig. 1 and 3, in some embodiments, the elastic assembly 30 includes a slider 31 and an elastic member 32. The sliding member 31 is slidably connected to the abutment plate 10, specifically, one end of the sliding member 31 is connected to the handle 50, and the other end sequentially slides through the abutment plate 10 and the accommodating gap 21 to be connected to the pressing plate 20; the elastic piece 32 is sleeved at one end of the sliding piece 31 to elastically pull the sliding piece 31 and drive the pressing plate 20 to elastically press the workpiece 200, specifically, the elastic piece 32 is sleeved on the sliding piece 31 and is located at one side of the abutting plate 10 away from the pressing plate 20, one end of the elastic piece 32 abuts against the abutting plate 10, the other end of the elastic piece 32 abuts against one end of the sliding piece 31 away from the pressing plate 20, and the sliding piece 31 slides relatively against the abutting plate 10 under the action of the elastic piece 32 and drives the pressing plate 20 to move close to the abutting plate 10. The elastic member 32 may be a spring or other elastic member.

In this way, the pressing plate 20 is driven and the pressing plate 20 is far away from the abutting plate 10, then one end of the workpiece 200 is erected on the supporting convex step 11, the other end of the workpiece 200 is placed in the accommodating gap 21, then the pressing plate 20 is loosened, at the moment, the elastic piece 32 drives the sliding piece 31 to slide, the sliding piece 31 drives the pressing plate 20 to move close to the abutting plate 10 and presses the pressing plate 20 against the workpiece 200, and therefore the workpiece 200 is fixed, and the fixing mode of the workpiece 200 is simple and quick to operate.

Referring to fig. 1 and 3, in some embodiments, the number of the pressing plates 20 is plural, the number of the sliding members 31, the elastic members 32, and the elastic protrusions 12 is plural, and the number of the sliding members 31, the elastic members 32, the elastic protrusions 12, and the pressing plates 20 are the same, one end of the sliding members 31 is connected to one handle 50 at intervals, and the elastic protrusions 12 are protruded from the abutting plate 10 at intervals.

The number of the pressing plates 20 in this embodiment is two, and the two pressing plates 20 are disposed at intervals along a first direction, which is a Z-axis direction in fig. 1, and in other embodiments, the two pressing plates 20 may be disposed along an X-axis. Thus, by arranging two pressing plates 20 and enabling the two pressing plates 20 to simultaneously press against the workpiece 200, the workpiece 200 is more firmly fixed.

Referring to fig. 3, in some embodiments, the pressing plate 20 is provided with a plurality of pressing portions 22 protruding thereon, and the plurality of pressing portions 22 are disposed on opposite sides of the pressing plate 20 along the second direction. The second direction is the X-axis direction in fig. 1. Specifically, each side of the pressing plate 20 may be provided with one pressing portion 22 or two or more pressing portions 22 at an inclination. When the workpiece 200 is fixed, the pressing portion 22 abuts against the surface of the workpiece 200, and presses the workpiece 200 against the abutment plate 10. Because the pressing parts 22 are obliquely and convexly arranged on the opposite sides of the pressing plate 20 at the same time, when an operator clamps the workpieces 200, the operator can clamp two workpieces 200 at the same time, thereby being beneficial to improving the detection efficiency of the workpieces 200; in addition, when clamping the workpiece 200, the operator can clamp the workpiece 200 on any side of the compacting plate 20, thereby providing convenience for the operator's operation.

Referring to fig. 3, the ends of the two sliding members 31 away from the pressing plate 20 are connected to the handle 50, and at this time, the ends of the elastic members 32 away from the abutting plate 10 abut against the handle 50. When fixing the workpiece 200, the operator pushes the handle 50 and moves the handle 50 close to the abutment plate 10, at this time, the elastic member 32 is compressed, then the workpiece 200 is placed in the receiving space 21, and then the handle 50 is released. At this time, the elastic member 32 pushes the handle 50 to move away from the abutment plate 10, and drives the pressing plate 20 to abut against the surface of the workpiece 200 through the sliding member 31. In this way, the plurality of sliders 31 are connected by using the handle 50, so that when the workpiece 200 is fixed, an operator can drive the plurality of pressing plates 20 to move simultaneously by pressing the handle 50, thereby facilitating the operation of the operator.

Referring to fig. 3, in some embodiments, the plurality of supporting steps 11 are plural, and the plurality of supporting steps 11 are spaced apart along the first direction. The support convex step 11 in the present embodiment includes a first support convex step 111 and a second support convex step 112, and the first support convex step 111 and the second support convex step 112 are connected to form a stepped shape. When fixing the workpiece 200, an operator can support the workpieces 200 with different heights against different supporting convex steps 11, so that the workpieces 200 are positioned in the first direction, and workpieces with different sizes can be detected conveniently.

The workpiece pressing mechanism 300 further comprises a screw 301, one end of the sliding piece 31 is provided with a square step head 311, the end face of the square step head 311 is provided with a screw hole 312, the pressing plate 20 is sleeved on the square step head 311, a screw cap of the screw 301 is clamped on the outer surface of the pressing plate 20, and a screw rod of the screw 301 penetrates through the pressing plate 20 and is locked in the screw hole 312 so as to lock the pressing plate 20 on the square step head 311.

Referring to fig. 1, in some embodiments, the detecting device 100 further includes a detecting member 60, a supporting rod 70, a mounting base 80, an adjusting member 90, and a base 91. The supporting rod 70 is movably arranged on the base 91 and is arranged at intervals with the abutting plate 10, the length direction of the supporting rod 70 is parallel to the first direction, the bottom of the supporting rod 70 is arranged on a base 91, and the base 91 slides on the measuring platform 40.

The mounting seat 80 is slidably sleeved on the support rod 70 and is used for mounting the detecting element 60, the detecting element 60 in the embodiment is a dial indicator, and the detecting element 60 is provided with a connecting rod 62. The adjusting member 90 is mounted on the mounting base 80 and is used for abutting against the supporting rod 70 to fix the mounting base 80 on the supporting rod 70. The adjusting member 90 in this embodiment is screwed on the mounting seat 80, and when the adjusting member 90 is screwed, the adjusting member 90 will abut against the surface of the mounting seat 80, so as to achieve the purpose of fixing the mounting seat 80; when the adjusting member 90 is unscrewed, the mounting base 80 can slide relative to the support rod 70, thereby achieving the purpose of adjusting the position of the mounting base 80. In this way, during the process of detecting the workpiece 200, an operator can adjust the position of the mounting seat 80 according to the size and the structural characteristics of the workpiece 200, thereby meeting the actual use requirement.

Referring to fig. 1 and 4, in some embodiments, the detecting device 100 further includes a probe 61, where the probe 61 is slidably mounted on the mounting base 80, one end of the probe 61 is connected to the detecting member 60, and the other end of the probe 61 abuts against the workpiece 200. The probe 61 comprises a sliding rod 611 and a probe head 612, and the sliding rod 611 and the probe head 612 are vertically connected to form an L-shaped structure; the probe 612 has a bevel 6121 and a horizontal surface 6122 thereon, the bevel 6121 and the horizontal surface 6122 provide a tapered end of the probe 612 to facilitate insertion of the probe 612 into a recess or hole in the workpiece 200 during inspection. Specifically, the probe 612 is provided with a probe portion 6123, and the probe portion 6123 is used for abutting against the workpiece 200 to detect the workpiece 200, and the contact area between the probe portion 6123 and the workpiece 200 is smaller than the whole horizontal plane 6122, which is beneficial to improving the detection accuracy of the probe 612.

The mount 80 includes first horizontal block 81, second horizontal block 82, perpendicular piece 83 and fixed block 84, slide bar 611 slides and passes first horizontal block 81 in order to peg graft with the connecting rod 62 of detecting member 60, first horizontal block 81 and second horizontal block 82 interval set up, connecting rod 62 passes second horizontal block 82, first horizontal block 81, perpendicular piece 83, second horizontal block 82 connect gradually and form the U type, fixed block 84 perpendicular connection is in first horizontal block 81, slide bar 611 slides and passes fixed block 84, bracing piece 70 passes perpendicular piece 83 in order to peg graft with base 91, regulating part 90 inserts and locates perpendicular piece 83 and support bar 70.

The probe 61 further comprises a limiting shaft 613, the limiting shaft 613 is disposed between the first horizontal block 81 and the second horizontal block 82, and the limiting shaft 613 is slidably inserted into one end of the sliding rod 611. The limiting shaft 613 plays a limiting role such that the sliding rod 611 does not separate from the first horizontal block 81.

In the detection process, when the detecting head 612 abuts against the workpiece 200, the detecting head 612 slides relative to the mounting seat 80, and meanwhile, the detecting head 612 drives the connecting rod 62 of the detecting member 60 to move, at this time, a reading appears on the detecting member 60, and an operator can obtain a detection result by observing the reading.

In this way, the probe 612 is connected with the sliding rod 611 to form an L-shaped structure, so that the probe 612 can extend into the hole or the groove during the measurement process, so as to measure the size of the hole or the groove structure, thereby making the detection device 100 more applicable.

Referring to fig. 1 and 2, in some embodiments, a plurality of zeroing steps 13 are respectively disposed on two sides of the abutment plate 10, the zeroing steps 13 are disposed along a first direction, the zeroing steps 13 are used to make the detecting element 60 near to zero, specifically, each zeroing step 13 is higher than the first supporting convex step 111, the heights of the zeroing steps 13 become gradually higher, and the height of the zeroing step 13 refers to the distance between the zeroing step 13 and the first supporting convex step 111, and the first supporting convex step 111 is closest to the measuring platform 40. For the frame-like workpiece 200, some protruding structures are usually disposed on the workpiece 200, when detecting the distance between the protruding and the end of the workpiece 200, the operator first abuts the probe 612 on the nearby zeroing step 13 to zero the detecting element 60, then moves the probe 612 to the protruding, at this time, reads the reading of the detecting element 60, and finally sums the reading with the height of the zeroing step 13 to obtain the position of the protruding. Thus, the problem of insufficient detection travel of the detection member 60 can be effectively avoided by providing the zeroing step 13.

Some embodiments provide a detection device that works substantially as follows:

firstly, an operator presses the handle 50 to enable the handle 50 to elastically approach the abutting plate 10 under the action of the elastic piece 32, and at the moment, the handle 50 drives the sliding piece 31 to move and enables the compacting plate 20 to move away from the abutting plate 10; then, one end of the workpiece 200 is installed on the supporting convex step 11, the other end of the workpiece 200 is placed in the accommodating gap 21, and the handle 50 is released, at the moment, the elastic piece 32 pushes the handle 50 to move away from the abutting plate 10, so that the handle 50 drives the pressing plate 20 to abut against the workpiece 200 through the sliding piece 31, and the workpiece 200 is pressed against the abutting plate 10, thereby completing the fixation of the workpiece 200; then, the probe 612 is abutted against the zeroing step 13 to zeroe the detecting element 60, and then the probe 612 is moved to a position on the workpiece 200 to be detected, and at the moment, the reading on the detecting element 60 is read; finally, the position size is obtained by summing the reading and the height size of the zeroing step 13 to determine whether the structure on the workpiece 200 is in place.

According to the detection device provided by the embodiment of the application, since the workpiece 200 is directly clamped on the detection device 100, the workpiece 200 is not required to be mounted on the clamping jig, so that the clamping efficiency of the workpiece 200 is improved, in addition, when the workpiece 200 is clamped or disassembled, an operator only needs to press or loosen the handle 50, so that the clamping and disassembling operations of the workpiece 200 are simple, and the efficiency of detecting the workpiece 200 is improved.
