In a specific application, since the elastic component 130 includes a shell 131, an elastic member 132 and a contact member 133, the shell 131 forms a accommodating cavity 1311, the shell 131 is rotatably connected relative to the base plate 110, the contact member 133 moves in the accommodating cavity 1311, and the elastic member 132 is located between the shell 131 and the contact member 133. In addition, at least two elastic components 130 are circularly surrounded on the base plate 110, and the elastic component 130 is arranged opposite to the clamping member 120, so that the contact member 133 and the clamping member 120 cooperate to clamp the chip tray, thereby allowing the mother-and-child ring fixture 100 to switch to clamp chip trays of different sizes. In this way, the mother-and-child ring fixture 100 can switch to clamp chip trays of different sizes, such as 6-inch or 8-inch tray trays (chip trays), thereby avoiding the problem of single feeding and low efficiency of the placement machine feed tray.

[0030] In a possible implementation, the clamping member 120 includes a connecting portion 121, an elastic portion 122, and a guide portion 123. The connecting portion 121 is fixedly connected to the bottom plate 110, the guide portion 123 is arranged in a V shape, and the elastic portion 122 is connected to the connecting portion 121 and the guide portion 123. In a specific application, in order to enable the clamping member 120 to conveniently clamp the tray, the clamping member 120 includes a connecting portion 121, an elastic portion 122, and a guide portion 123. The connecting portion 121 is fixedly connected to the bottom plate 110, the guide portion 123 is arranged in a V shape, and the elastic portion 122 is connected to the connecting portion 121 and the guide portion 123. The front end of the guide portion 123 arranged in a V shape can guide the tray into the clamping member 120, and the rear end of the guide portion 123 arranged in a V shape is connected to the elastic portion 122, which can effectively fix the tray on the bottom plate 110.

[0031] In a possible implementation, the contact member 133 further includes a wedge-shaped portion 1331, the wedge-shaped portion 1331 is located at one end away from the accommodating cavity 1311, and the wedge-shaped portion 1331 forms an oblique section 13311 inclined toward the accommodating cavity 1311, and the oblique section 13311 is arranged opposite to the guide portion 123. In a specific application, since the wedge-shaped portion 1331 is located at one end away from the accommodating cavity 1311, and the wedge-shaped portion 1331 forms an oblique section 13311 inclined toward the accommodating cavity 1311, and the oblique section 13311 is arranged opposite to the guide portion 123, when the contact member 133 abuts against the tray, the oblique section 13311 of the wedge-shaped portion 1331 can be used to cooperate with the guide portion 123 of the clamping member 120 to press and lock the tray on the bottom plate 110.

[0032] In a possible implementation, the contact member 133 further includes a sliding portion 1332, the sliding portion 1332 is arranged close to the accommodating cavity 1311, and the sliding portion 1332 is perpendicular to the contact member 133, the housing 131 is formed with a slide groove 1312 penetrating the accommodating cavity 1311, and the sliding portion 1332 is movably connected to the slide groove 1312. In a specific application, in order to improve the smoothness of the contact member 133 when it moves in the accommodating cavity 1311, the sliding portion 1332 is arranged close to the accommodating cavity 1311, and the sliding portion 1332 is perpendicular to the contact member 133, the housing 131 is formed with a slide groove 1312 penetrating the accommodating cavity 1311, and the sliding portion 1332 is movably connected to the slide groove 1312, wherein the sliding portion 1332 is a roller rolling on the slide groove 1312, which can reduce the friction between the contact member 133 and the accommodating cavity 1311.

[0033] In a possible implementation, the elastic component 130 further includes a latch 134, and the housing 131 is formed with a connection hole 1313. The latch 134 is inserted into the connection hole 1313 to connect with the bottom plate 110, and the housing 131 rotates relative to the latch 134. In a specific application, in order to enable the elastic component 130 to be rotatably connected to the bottom plate 110, a connection hole 1313 is provided on the housing 131, and the latch 134 is inserted into the connection hole 1313 to connect with the bottom plate 110, and the housing 131 rotates relative to the latch 134, so that the elastic component 130 can rotate relative to the bottom plate 110 to clamp trays of different sizes.

[0034] In a possible implementation, the shell 131 is formed with an arc portion 1314, the arc portion 1314 is located at the exit of the accommodating cavity 1311, and the center of the arc portion 1314 is located at the rotation center of the connecting hole 1313. In a specific application, when the elastic component 130 rotates, there will be a certain friction between the edge of the shell 131 and the tray. In order to reduce the wear on the tray, the shell 131 is formed with an arc portion 1314, and the arc portion 1314 is located at the exit of the accommodating cavity 1311, and the center of the arc portion 1314 is located at the rotation center of the connecting hole 1313. In this way, the wear on the tray can be reduced by the central rotation of the arc portion 1314.

[0035] In a possible implementation, the housing 131 is further formed with a brake portion 1315, which is located below the housing 131 away from the connection hole 1313, and abuts against the bottom plate 110. In a specific application, in order to avoid the risk of displacement of the clamping tray when the elastic component 130 is rotated into place, a brake portion 1315 is further formed on the housing 131, which is located below the housing 131 away from the connection hole 1313, and abuts against the bottom plate 110. When the clamping member 120 is displaced, the brake portion 1315 below the housing 131 contacts the bottom, which can reduce the accidental rotation of the elastic component 130.

[0036] In a possible embodiment, the mother-and-child ring fixture 100 also includes an annular buckle plate 140, which is connected to the base plate 110, and the buckle plate and the base plate 110 form a buckle groove 141. In specific applications, since the conventional sizes of trays are divided into 6 inches / 8 inches / 12 inches, in order to facilitate the replacement of 6-inch / 8-inch trays on the placement machine, the mother-and-child ring fixture 100 in this case can be used for efficient switching to improve operating efficiency. If only a 12-inch tray operation is required, the annular buckle plate 140 on the mother-and-child ring fixture 100 can be used. The annular buckle plate 140 is connected to the base plate 110, and the buckle plate and the base plate 110 form a buckle groove 141, and the 12-inch tray is clamped through the buckle groove 141.

[0037] In a possible implementation, the annular buckle plate 140 is formed with an escape opening 142, which extends flush with the bottom of the snap-fit ​​groove 141. In a specific application, in order to facilitate the disassembly and assembly of a 12-inch tray, an escape opening 142 is formed on the annular buckle plate 140, and the escape opening 142 extends flush with the bottom of the snap-fit ​​groove 141, so that the 12-inch tray can be conveniently replaced through the escape opening 142.

[0038] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
