All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1 to 3, fig. 1 to 3 are a front view, a top view and a cross-sectional view a-a of fig. 1 of a workpiece 1 detected by the jitter detection apparatus of the present application.

The workpiece 1 is substantially cup-shaped, and the center of the workpiece 1 is provided with a hole 101 penetrating along the axial direction and an abutting surface 102. The hole 101 is cylindrical. The abutting surface 102 is a circular plane surrounding the hole 101. In the present embodiment, the three positions to be detected of the workpiece 1 need to be subjected to the jumping detection, which are the first position to be detected P1, the second position to be detected P2 and the third position to be detected P3.

The workpiece 1 is merely an example, and in other embodiments, the workpiece 1 may have other structures, but needs to have the hole 101 and the abutting surface 102. The specific shape of the hole 101 and the interference surface 102 is not limited.

Referring to fig. 4 to 11, fig. 4 to 6 are a front view, a top view and a right side view of an embodiment of the runout detecting apparatus of the present application, respectively, fig. 4 omits a position detecting member 400, fig. 7 and 8 are a front view and a top view of a carrier table 111 in the runout detecting apparatus shown in fig. 1, fig. 9 is a sectional view B-B in fig. 7, fig. 10 is an enlarged view of C in a partial view of fig. 9, and fig. 11 is a schematic view of the carrier table 111 carrying a workpiece 1.

The jitter detection apparatus includes a carrier assembly 100 and a jitter detection assembly 300. The bearing assembly 100 includes a bearing platform 111, a first driving member 120 and a positioning member 112. The runout detecting assembly 300 includes runout detecting members (hereinafter, a first runout detecting member 301, a second runout detecting member 302, and a third runout detecting member 303).

The bearing table 111 has a bearing surface 111a, and the bearing surface 111a is used for bearing the workpiece 1. Specifically, the bearing surface 111a is located on the top of the bearing table 111, and the bearing surface 111a is a plane. After the workpiece 1 is placed on the bearing table 111, the bearing surface 111a is at least partially attached to the abutting surface 102 of the workpiece 1.

The susceptor 111 has a first suction hole 111b formed on a supporting surface 111 a. The first suction hole 111b is used to communicate with a negative pressure source (not shown) to suck the workpiece 1. Specifically, the bearing platform 111 is a hollow structure, the first suction holes 111b are communicated with a cavity of the bearing platform 111, and the cavity of the bearing platform 111 is communicated with a negative pressure source. The number of the first adsorption holes 111b may be one or more, and may be set according to specific requirements. The first suction holes 111b are opened in a region where the bearing surface 111a and the interference surface 102 are abutted. Under the action of the negative pressure source, the cavity of the bearing table 111 is in a negative pressure state, so that the first adsorption holes 111b can adsorb the workpiece 1, and the workpiece 1 is further fixed on the bearing table 111. The negative pressure environment in the cavity of the susceptor 111 is destroyed, and the restriction of the work 1 can be released.

The positioning member 112 is protruded from the bearing surface 111a, and is configured to be inserted into the hole 101 of the workpiece 1 and cooperate with the hole 101 to position the workpiece 1. The positioning member 112 and the hole 101 are matched in shape and size, so that the positioning member 112 can be inserted into the hole 101 without relative shaking between the workpiece 1 and the positioning member 112. In the embodiment, the hole 101 is cylindrical, and correspondingly, the positioning element 112 is cylindrical. In this embodiment, the positioning member 112 and the platform 111 are an integral structure, but in other embodiments, the positioning member may be a separate structure.

The carrier 111 can rotate around its axis. The first driving member 120 is used for driving the bearing platform 111 to rotate. Specifically, the bearing platform 111 is fixedly disposed at the driving end of the first driving member 120. The first drive member 120 is a rotary drive, which may optionally be prior art.

The jumping detection part is used for detecting jumping of the workpiece 1. In this embodiment, the number of the jumping detection pieces is three, and the jumping detection is performed on the first to-be-detected position P1, the second to-be-detected position P2, and the third to-be-detected position P3, respectively. The jumping detection piece can be a dial indicator or a displacement sensor. In this embodiment, since the specification of the workpiece 1 is small, a displacement sensor is used. The displacement sensor is preferably a laser sensor. The laser sensor is optionally prior art. The principle of the laser sensor for detecting the jitter is as follows: the method comprises the steps of detecting the distance between a laser sensor and a position to be tested of a workpiece 1 through the laser sensor, storing distance data, and subtracting a peak value and a valley value in the distance data after the workpiece 1 rotates for a circle to obtain a jump value.

The working process is as follows:

the workpiece 1 is placed on the bearing surface 111a, and the positioning member 112 is inserted into the hole 101 of the workpiece 1. The workpiece 1 is sucked through the first suction hole 111b, and the workpiece 1 is fixed. The first driving member 120 acts to drive the bearing platform 111 to rotate, and the bearing platform 111 drives the workpiece 1 to rotate. The runout detecting member detects a runout value at a position to be detected of the workpiece 1. After the inspection is completed, the workpiece 1 is removed from the stage 111.

In the present application, after the workpiece 1 is placed on the bearing surface 111a of the bearing table 111, the positioning member 112 protruding from the bearing surface 111a is inserted into the hole 101 of the workpiece 1 to position the workpiece 1, and the first suction holes 111b on the bearing surface 111a suck the workpiece 1 to fix the workpiece 1, so that the positioning and fixing manner is not affected by the specification and size of the workpiece 1, and the positioning and fixing of the workpiece 1 with smaller specification is facilitated.

In order to automatically place the workpiece 1 on the carrier table 111 or remove the workpiece 1 from the carrier table 111, the jumping detection apparatus further includes a handling assembly 200 in this embodiment. The conveying assembly 200 is used for conveying the workpiece 1. Before the inspection, the conveying assembly 200 conveys the workpiece 1 from the first station to the loading platform 111. After the detection, the conveying assembly 200 conveys the workpiece 1 from the bearing platform 111 to the second station. The first and second stations may be the same or different.

Specifically, the handling assembly 200 includes a second drive 210, a third drive 220, a first mount 230, and a gripper 240.

The third driving element 220 is disposed at the driving end of the second driving element 210, and the second driving element 210 is used for driving the third driving element 220 to move along the first direction D1 or the first direction D1 in the opposite direction. The second driver 210 may be a linear motor.

The first mounting seat 230 is disposed at a driving end of the third driving member 220, the third driving member 220 is used for driving the first mounting seat 230 to move along a second direction D2 or a second direction D2, and the second direction D2 intersects with the first direction D1. In this embodiment, the second direction D2 is perpendicular to the first direction D1. The third driver 220 may be a cylinder.

A gripping member 240 is connected to the first mounting block 230 for gripping or releasing the workpiece 1.

Because the size of the workpiece 1 is smaller, in order to conveniently grab the workpiece 1, in this embodiment, the grabbing member 240 has a second adsorption hole (not visible in the figure) for communicating with the negative pressure source to adsorb the workpiece 1, and further grab the workpiece 1 in a vacuum adsorption manner. The grasping member 240 may be a vacuum chuck, a cavity of the vacuum chuck is used for communicating with a negative pressure source, when a negative pressure is formed in the vacuum chuck, the vacuum chuck can adsorb the workpiece 1, and after the vacuum environment is destroyed, the vacuum chuck releases the workpiece 1.

The second suction holes are also used for being communicated with a high-pressure air source and can blow air flow to blow the workpiece 1 against the bearing surface 111 a. In this embodiment, the cavity of the vacuum chuck is communicated with the high-pressure gas source, and the workpiece 1 is blown against the bearing surface 111a of the bearing table 111 by inputting the high-pressure gas into the cavity of the vacuum chuck. With this arrangement, the workpiece 1 can be prevented from being damaged, and the workpiece 1 can be easily separated from the vacuum chuck.

Referring to fig. 12 to 14 together, fig. 12 and 13 are a front view and a left side view, respectively, of a partial structure of a carrier assembly 200 in the jump detecting apparatus, and fig. 14 is a cross-sectional view taken along line D-D of fig. 12.

In order to avoid the hard contact between the grasping element 240 and the workpiece 1, and thus avoid the damage to the workpiece 1, in the embodiment, the carrying assembly 200 further includes a second mounting seat 250 and a resilient element 260.

The second mounting base 250 is movably disposed on the first mounting base 230 and can move relative to the first mounting base 230 in the direction opposite to the second direction D2 or the second direction D2. Specifically, second mount 250 is slidably coupled to first mount 230 along second direction D2. The second mount 250 is also capable of interfering with the first mount 230 at the predetermined position to restrict the second mount 250 from moving in the second direction D2.

Opposite ends of the elastic member 260 are respectively connected to/abutted against the first mounting seat 230 and the second mounting seat 250, and are used for applying an elastic force to the second mounting seat 250 to drive the second mounting seat 250 to move along the second direction D2. Specifically, opposite ends of the elastic member 260 in the second direction D2 elastically abut against the first and second mounting seats 230 and 250, respectively. The elastic member 260 is always in a compressed state. The elastic member 260 may be a spring. In other embodiments, the elastic member 260 may be placed in a stretched state by proper arrangement.

The grabbing member 240 is disposed on the second mounting seat 250, and collides with the workpiece 1 along the second direction D2 to adsorb the workpiece 1.

The third driving member 220 drives the grasping member 240 to move in the second direction D2 to approach the workpiece 1. After the grasping element 240 abuts against the workpiece 1, the third driving element 220 continues to drive the grasping element 240 to move a distance along the second direction D2. In this process, the elastic member 260 plays a role of buffering, so that the grasping member 240 can be elastically pressed against the workpiece 1. On the one hand, damage to the workpiece 1 is avoided, on the other hand, the air tightness between the grabbing piece 240 and the workpiece 1 is improved, and the success rate of adsorption is improved.

Referring to fig. 4 to 6, in the process of placing the workpiece 1 on the supporting platform 111, the hole 101 of the workpiece 1 needs to be aligned with the positioning element 112. To align the hole 101 with the positioning member 112, the jumping detecting device further includes a position detecting member 400 and a controller (not shown), and correspondingly, the carrying assembly 200 further includes a fourth driving member 130.

The position detecting member 400 is used to acquire the position information of the workpiece 1 on the grasping member 240. The position detector 400 may be a CCD (charge coupled device) camera.

The fourth driving member 130 is used for driving the carrier stage 111 to move in the third direction D3 or the reverse direction of the third direction D3, and the third direction D3 is perpendicular to the first direction D1 and the second direction D2, respectively. Specifically, the first driving member 120 is disposed at the driving end of the fourth driving member 130. The fourth driver 130 may be a linear motor.

The controller is electrically connected to the position detecting element 400, the first driving element 120, the second driving element 210, and the fourth driving element 130, respectively, and is configured to control the first driving element 120, the second driving element 210, and the fourth driving element 130 to operate according to the position information obtained by the position detecting element 400.

After the position of the workpiece 1 is obtained by the CCD camera, the controller controls the first driving element 120, the second driving element 210 and the fourth driving element 130 to move, so that the workpiece 1 is sleeved on the positioning element 112 through the hole 101.
