[0035] The fixture and the tray with the fixture in this embodiment are used in semiconductor processing equipment, such as cutting and sorting machines, where the processing equipment processes materials such as chips, and the materials are transported by the tray as a carrier.
[0036] <Example 1>
[0037] like Figures 1 to 10As shown, this embodiment provides a fixture 1 for accommodating and locking or releasing a material tray 2, thus enabling the detachability of the material tray 2, which is used to accommodate workpieces. The fixture 1 includes a main body 100, which has a receiving cavity 110 for accommodating the material tray 2. The receiving cavity 110 has side walls 111 around its periphery to limit the movement of the material tray 2. The receiving cavity 110 is recessed into the upper surface 120 of the main body 100, and its shape can be set according to the shape of the material tray 2. A guide wall 112 is provided above the side walls 111, and the guide wall 112 is inclined outwards to facilitate the placement of the material tray 2. The accommodating cavity 110 is provided with a pushing assembly 200 and a pressing assembly 300 on its periphery. The pushing assembly 200 includes a push rod 210 and a mounting base 220. The push rod 210 is telescopically mounted on the mounting base 220. The push rod 210 locks or releases the tray 2 in the accommodating cavity 110. The push rod 210 moves horizontally and can extend and retract relative to the mounting base 220, allowing it to extend into the accommodating cavity 110, thereby pushing the tray 2. The push rod 210 has a pushing surface 211 and a first pressing surface 212. The pushing surface 211 applies a pushing force to the tray 2, which is a force parallel to the upper surface 120, causing the tray 2 to press tightly against the side wall 111 and be limited in the horizontal direction. The first pressing surface 212 applies pressure to the tray 2, which is perpendicular to the pushing force, allowing the tray 2 to be pressed down. The first pressing surface 212 can also apply pressure or a pushing force simultaneously, but at least pressure must be applied, so as to press the tray 2 down and prevent it from popping out of the accommodating cavity 110. The pushing assembly 200 and the pressing assembly 300 are arranged opposite to each other. The pressing assembly 300 applies pressure to the tray, thereby applying downward pressure to the tray 2 through the pushing assembly 200 and the pressing assembly 300 at different positions, so that it can be firmly locked in the receiving cavity 110 and prevent it from falling out. With the above technical solution, for small trays with irregular shapes (equivalent to tray 2), a jig can be used as a carrier. The tray can be transferred by simply fixing it in the jig through the pressing assembly and the pushing assembly. The jig is compatible with trays of different sizes and has good versatility. By extending and retracting the push rod 210, the push rod 210 extends when there is no tray 2; when the tray 2 is inserted, the first pressing surface 212 and the pushing surface 211 of the push rod apply downward pressure and lateral thrust to the tray 2, so that the tray 2 can be stably fixed in the receiving cavity 110; when the tray 2 is to be removed, the push rod 210 retracts to release the tray 2. The fixture in this embodiment can be used as a transfer fixture. Using a transfer fixture only requires designing a main body 100 that is similar in shape to a standard pallet, without the need to design a new pallet storage structure separately.
[0038] like Figures 1 to 3As shown, further, the pushing assembly 200 and the pressing assembly 300 are disposed opposite each other at the end corner 130 of the receiving cavity 100. The end corner 130 is the position where the two sides of the receiving cavity 100 intersect. The direction of the push rod 210 is towards the pressing assembly 300. The pushing force applied by the push rod 210 is along the diagonal direction of the receiving cavity 100. The end corner 130 corresponds to the corner 21 of the material tray 2. When the material tray 2 is locked, the pushing force of the push rod 210 is applied to one corner 21, so that it can be more stable in the receiving cavity 100. The push rod 210 and the pressing assembly 300 respectively press the corner 21 of the material tray 2, pressing the material tray 2 from the two ends furthest apart, so that the entire material tray 2 is firmly pressed. In this embodiment, the receiving cavity 100 and the material tray 2 are rectangular. Specifically, the end corner 130 is provided with a groove 140, and the pushing component 200 and the pressing component 300 are disposed in the groove 140. The groove 140 can accommodate the pushing component 200 and the pressing component 300 so that they do not protrude from the upper surface 120 of the main body, thus avoiding collisions during use. The shape of the groove 140 is set according to the pushing component and the pressing component. Multiple grooves can adopt different shapes. In this embodiment, the groove 140 includes a first groove 141 and a second groove 142. The pushing component 200 is disposed in the first groove 141, and the pressing component 300 is disposed in the second groove 142.
[0039] like Figure 2 and Figure 8As shown, further, the first pressing surface 212 and the pushing surface 211 are connected and form an included angle α, so that the first pressing surface 212 faces obliquely downward, thereby being able to apply an obliquely downward force. In this embodiment, the included angle α is an obtuse angle, specifically, the angle of α is 135°, and the pushing surface 211 is vertically arranged. The first pressing surface 212 and the pushing surface 211 correspond to the oblique cut portion 22 of the frame 21 of the material tray 2. The frame 21 is arranged on the periphery of the material tray 2. After the material tray 2 is placed into the receiving cavity, the frame 21 abuts against the side wall 111 of the receiving cavity 110. In this embodiment, the frame 21 is rectangular and includes four side portions 201 connected in sequence. The first pressing surface 212 is in close contact with the beveled portion 22, thereby applying a pushing force to the beveled portion 22. The beveled portion 22 is located between adjacent side portions 201. Since the beveled portion 22 is inclined relative to the side portion 201, the horizontal pushing force of the pressing surface 211 can be decomposed into two components in two mutually perpendicular directions, thereby pressing the material tray 2 in two directions and making the material tray 2 more stable. In addition, the beveled portion 22 contacts the first pressing surface 212 and is pressed by the downward pressure of the first pressing surface 212. The clamping assembly 300 includes a clamping block 310, which is disposed on the main body 100 and fixed in the groove 140 by fasteners such as bolts. The clamping block 310 has a second clamping surface 313. When the second clamping surface 313 contacts the material tray 2, it applies pressure to the material tray 2. Through the relatively arranged first and second clamping surfaces, the material tray 2 can be clamped from both ends to prevent the material tray 2 from falling out of the receiving cavity during movement. The clamping block 310 has a connected first arm 311 and a second arm 312. The included angle between the first arm 311 and the second arm 312 corresponds to the angle of the end corner 130 of the receiving cavity 110. In this embodiment, the receiving cavity 110 is rectangular, the first and second arms are perpendicular to each other, and the clamping block 310 is L-shaped. The second clamping surface 313 extends from the first arm 311 to the second arm 312, expanding the range of the second clamping surface 313. When the tray 2 is placed into the receiving cavity 110, the first and second arm portions in two directions correspond to the frame 21 of the tray 2, and the two side portions 201 of the tray 2 are pressed together by the second pressing surface 313. Specifically, the second pressing surface 313 includes a connected inclined surface 3131 and a guide surface 3132. The inclined surface 3131 and the guide surface 3132 apply pressure to the frame 21. The guide surface 3132 is located above the inclined surface 3131, which facilitates the tray 2 to enter or leave the receiving cavity 110. The guide surface is arc-shaped.
[0040] like Figures 7 to 10As shown, the pressing assembly 200 further includes an elastic element 230 and a guide shaft 240 disposed in the mounting base 220. The elastic element 230 is sleeved on the guide shaft 240 and can be a spring. The push rod 210 is sleeved on the guide shaft 240 and presses against the elastic element 230. The tray 2 can be manually placed into the receiving cavity. One end of the tray 2 pushes against the push rod 210, the push rod 210 retracts, the elastic element 230 is compressed, and the other end is inserted under the clamping block 310. The elastic force of the elastic element 230 causes the push rod 210 to apply force to the tray 2. In this embodiment, the force provided by the elastic element 230 enables the tray 2 to be pressed and pushed. When the tray 2 is removed, the push rod 210 retracts, the tray 2 disengages from under the clamping block 310, and the tray 2 can be removed. Mounting base 220 is disposed in first groove 141, and there is a communication port 150 between first groove 141 and receiving cavity 110, through which push rod 210 can extend and retract within receiving cavity 110.
[0041] <Example 2>
[0042] In this embodiment, the parts that are the same as in Embodiment 1 are given the same reference numerals, and the same text descriptions are omitted.
[0043] like Figures 1 to 4 As shown, compared to Embodiment 1, this embodiment provides a tray, including the fixture of Embodiment 1. A material tray 2 is provided within the receiving cavity 110. The material tray 2 is detachable from the main body 100, allowing for the replacement of different material trays 2. The surface of the material tray 2 is provided with material grooves 23, spaced apart, for storing components such as chips. A frame 21 is provided around the periphery of the material tray 2. The frame 21 is locked or released by a pushing component 200 and a pressing component 300. When the frame 21 is locked, the material tray 2 will not detach from the receiving cavity; when the frame 21 is released, the material tray 2 can be removed. The main body 100 has several receiving cavities 110, enabling the accommodating of multiple material trays 2. In this embodiment, two material trays 2 are provided, with each receiving cavity 110 corresponding to a set of pushing components 200 and pressing components 300, allowing for individual control of the material tray 2 within each receiving cavity 110. By designing the frame of the main body 100 to resemble the frame of an existing standard tray, the existing equipment can perform gripping and releasing actions on the tray of this embodiment, and it is compatible with existing mechanical grippers and storage devices. Furthermore, when the processing equipment requires a small tray, the material tray 2 can be designed as a small tray, which can be used immediately after being removed from the fixture. That is, the material tray 2 can be used as a small tray, or it can be combined with the main body 100 to be used as a standard tray, thus significantly improving its versatility.
[0044] In the above embodiments one and two, during the working process, depending on the different working environments, some of the technical implementation methods of embodiments one and two can be combined or replaced.
[0045] The technical principles of this utility model have been described above in conjunction with specific embodiments. However, it should be noted that these descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, other specific embodiments or equivalent substitutions of this utility model that can be conceived by those skilled in the art without creative effort will all fall within the scope of protection of this utility model.
