[0036] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited to the described contents.

[0037] Embodiment 1:

[0039] The fixed plate 1 is provided with a movable plate 5, and a cushion block is provided between the fixed plate 1 and the movable plate 5. The movable plate 5 is supported by the cushion block to limit the setting height of the movable plate 5, and at the same time, the friction of the movable plate 5 is reduced, so that the movable plate 5 moves more smoothly. The cushion block is cylindrical, square or other shapes, and the number of cushion blocks can be set according to the size of the movable plate 5. The movable plate 5 is provided with a limiting guide hole 501, and the limiting guide hole 501 is a waist-shaped hole. The fixed plate 1 is provided with a guide column 101, and the upper end of the guide column 101 passes through the limiting guide hole 501. The diameter of the guide column 101 matches the width of the limiting guide hole 501, thereby limiting the movable direction of the movable plate 5; in some specific embodiments, the position of the limiting guide hole 501 is set in a one-to-one correspondence with the position of the cushion block.

[0040] The fixed plate 1 is provided with two groups of side limit blocks 7 arranged opposite to each other, and each group of the side limit blocks 7 includes two square side limit blocks 7.

[0041] The left side of the chip clamping station 2 is provided with a fixed limit block 3 fixedly connected to the fixed plate 1. It can be imagined that the upper end of the fixed limit block 3 also passes through the moving plate 5 upward, and the moving plate 5 is also provided with a clearance hole corresponding to the position of the fixed limit block 3, so that the moving plate 5 will not interfere with the fixed limit block 3; the right side of the chip clamping station 2 is provided with a movable limit block 4 fixedly connected to the moving plate 5, wherein the movable limit block 4 can be moved in a direction close to or away from the fixed limit block 3 under the drive of the moving plate 5; in this way, when the chip needs to be transported or transferred, the chip is placed on the chip clamping station 2, and the front and rear sides of the chip are limited by the side limit blocks 7; then the movable limit block 4 or the moving plate 5 is pushed to make the movable limit block 4 move toward the fixed limit block 3, so that the left and right sides of the chip are limited by the fixed limit block 3 and the movable limit block 4, so as to achieve the purpose of firmly clamping the chip in the chip clamping station 2, so as to facilitate the transportation or transfer of the chip.

[0042] In this embodiment, when the guide column 101 contacts one end of the limit guide hole 501, the two sides of the chip are respectively in contact with the fixed limit block 3 and the movable limit block 4. In this way, the distance that the movable plate 5 can move is limited, that is, the distance that the movable limit block 4 can move to the left is limited, which effectively avoids the problem of the chip being crushed due to the excessive movement of the movable limit block 4, thereby ensuring the safety of the chip.

[0043] In this embodiment, a first limiting slope 301 is provided on the top of the fixed limiting block 3. The first limiting slope 301 is in point contact or line contact with the upper side edge of the chip located in the chip clamping station 2. The chip is pressed in the chip clamping station 2 through the first limiting slope 301. At the same time, the problem of excessive pressure on a part of the chip causing damage to the chip due to insufficient edge flatness of the chip is avoided, and the problem of excessive pressure on a part of the chip causing damage to the chip due to insufficient edge flatness of the fixed limiting block 3 is avoided. The safety of chip clamping is effectively improved.

[0044] Preferably, the angle between the projection of the first limiting slope 301 on the vertical plane and the horizontal plane is 30 degrees to 55 degrees, such as 30 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees and any angle between 30 degrees and 55 degrees; the height of the side surface of the chip is higher than the height of the lowest point of the first limiting slope 301, and lower than the height of the highest point of the first limiting slope 301.

[0045] In this embodiment, a second limiting slope 401 is provided on the top of the movable limiting block 4, and the second limiting slope 401 is in point contact or line contact with the upper side edge of the chip located in the chip clamping station 2. The chip is pressed in the chip clamping station 2 through the second limiting slope 401. At the same time, the problem of excessive pressure on a part of the chip area causing damage to the chip due to insufficient edge flatness of the chip is avoided, and the problem of excessive pressure on a part of the chip area causing damage to the chip due to insufficient edge flatness of the movable limiting block 4 is avoided; the safety of chip clamping is effectively improved.

[0046] Preferably, the angle between the projection of the second limiting slope 401 on the vertical plane and the horizontal plane is 30 degrees to 55 degrees, such as 30 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees and any angle between 30 degrees and 55 degrees; the height of the side surface of the chip is higher than the height of the lowest point of the second limiting slope 401, and lower than the height of the highest point of the second limiting slope 401.

[0047] In this embodiment, a guiding slope 701 is provided on the top of the side limit block 7, and the guiding slope 701 guides the process of placing the chip into the chip clamping station 2 to ensure that the chip can be placed in the chip clamping station 2 smoothly and correctly.

[0049] In this embodiment, the movable stop block 4 is cylindrical, square or other shapes, and the top of the movable stop block 4 is conical to guide the process of placing the chip into the chip clamping station 2.

[0050] In this embodiment, after the locking screw passes through the movable disk 5, it is threadedly connected with the fixed disk 1. In this way, after the movable disk 5 is pushed to the specified position, the position of the movable disk 5 can be fixed by simply tightening the locking screw. It is easy to use. Preferably, the end of the locking screw is butterfly-shaped, which improves the convenience of rotating the locking screw.

[0051] Embodiment 2:

[0052] See also Figure 5-Figure 8 The present application provides a chip handling or cleaning fixture, including a fixed plate 1, a fixed limit block 3, a movable limit block 4, a side limit block 7, and a load-bearing block.

[0053] The fixed plate 1 is provided with two groups of side limit blocks 7 which are arranged opposite to each other, each group of the side limit blocks 7 includes two square side limit blocks 7, and the cavity between the two groups of the side limit blocks 7 is a chip clamping station 2, and the chip clamping station 2 is provided with a load-bearing block for carrying the chip. At the same time, the chip is carried by the load-bearing block, which reduces the contact area with the chip compared to placing the chip directly on the fixed plate 1, and the chip is more convenient to move. Furthermore, there is a certain gap between the chip and the fixed plate 1 to facilitate the outflow of water when the chip is cleaned.

[0054] A fixed limit block 3 is provided on the left side of the chip clamping station 2 for limiting the left side of the chip. A slide groove 102 is provided on the right side of the chip clamping station 2. A movable limit block 4 is slidably installed in the slide groove 102. The movable limit block 4 is used to limit the right side of the chip.

[0055] When the chip needs to be cleaned, the chip is placed in the chip clamping station 2, and then the movable limit block 4 is pushed to move along the slide groove 102, so that the movable limit block 4 moves closer to the fixed limit block 3, thereby firmly clamping the chip in the chip clamping station 2, and then the entire fixture is installed in the chip cleaning device for cleaning, which is beneficial to improve the cleaning efficiency of the chip.

[0056] In this embodiment, the movable limit block 4 is roughly square, and the top of the side of the movable limit block 4 close to the chip clamping station 2 is provided with a limit portion extending toward the chip clamping station 2, and the bottom surface of the limit portion is inclined to form the limit slope. When clamping the chip, the limit slope is in point contact or line contact with the upper side edge of the chip located in the chip clamping station 2, so that the chip is pressed in the chip clamping station 2 through the limit slope. At the same time, the problem of excessive pressure on part of the chip due to insufficient edge flatness of the chip, resulting in damage to the chip, is avoided, and the problem of excessive pressure on part of the chip due to insufficient edge flatness of the fixed limit block 3, resulting in damage to the chip, is also avoided; the safety of chip clamping is effectively improved.

[0057] Preferably, the angle between the projection of the limiting slope on the vertical plane and the horizontal plane is 30 degrees to 55 degrees; such as 30 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees and any angle between 30 degrees and 55 degrees; the height of the side surface of the chip is higher than the height of the lowest point of the limiting slope and lower than the height of the highest point of the limiting slope.

[0058] In this embodiment, two limiting parts are provided, which are symmetrically distributed about the center line of the chip clamping station 2, and the chip is limited by multiple points, so as to further improve the stability of chip clamping.

[0059] In this embodiment, a waist-shaped limiting hole 402 is provided on the movable limiting block 4. After the locking screw passes through the waist-shaped limiting hole 402, it is screwed together with the fixed plate 1; when the movable limiting block 4 is pushed to the specified position (when the movable limiting block 4 is against the chip), the locking screw is tightened to fix the position of the movable limiting block 4, so as to avoid the problem of chip falling off caused by the movement of the movable limiting block 4 during the cleaning process, thereby ensuring the stability of chip clamping.

[0060] Preferably, when one side of the chip located in the chip clamping station 2 abuts against the fixed limit block 3, the locking screw abuts against the right inner side surface of the waist-shaped limit hole 402. In this way, the movable distance of the movable limit block 4 is limited through the cooperation of the waist-shaped limit hole 402 and the locking screw, thereby avoiding the technical problem of the chip being crushed due to the excessive movement of the movable limit block 4, thereby ensuring the safety of the chip during the chip clamping process.

[0061] In this embodiment, the fixed limit block 3 is roughly cylindrical, and includes a connecting portion, a buttress portion, and a guide portion distributed in sequence from bottom to top; the connecting portion is fixedly connected to the fixed plate 1, the top surface of the connecting portion, the bottom surface and the top surface of the guide portion are inclined, and the diameter of the buttress portion is smaller than the diameter of the connecting portion and smaller than the diameter of the guide portion. When clamping the chip, the buttress portion contacts the side line of the chip to limit the chip. The top surface of the connecting portion, the bottom surface and the top surface of the guide portion are inclined so that the upper and lower sides of the chip can be completely exposed to ensure that the chip can be cleaned. At the same time, it can play an upper and lower limit effect on the chip to ensure that the chip is firmly clamped.

[0062] In this embodiment, the top of the side limit block 7 is conical, so as to guide the process of placing the chip into the chip clamping station 2, so as to ensure that the chip can be placed in the chip clamping station 2 smoothly and correctly.

[0063] In this embodiment, four slide grooves 102 are distributed in a cross shape on the fixed plate 1, and the drainage grooves penetrate the outer circumference of the fixed plate 1 along the radial direction of the fixed plate 1 from the outer ends of the slide grooves 102. In this way, when cleaning the chip, the cleaning agent can flow out of the fixture from the drainage grooves, effectively avoiding the technical problem of the cleaning solution accumulating on the fixture during cleaning.
