In addition, the terms "first", "second", "third" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0033] The specific embodiments of the present application will be described in detail below in connection with the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0034] The first aspect of the embodiments of the present application provides a material taking seat, as shown in the drawings, comprising a plurality of independently arranged blocks, the plurality of blocks are surrounded to form a material taking and dropping channel 1, the material taking and dropping channel 1 comprises a material guiding section 11 and a limiting section 12 in communication with the material guiding section 11, the material guiding section 11 gradually decreases in caliber along the direction of gradually approaching the limiting section 12, and the limiting section 12 is used to limit the position of the product relative to each block. Figures 1 to 3 As shown in the drawings, comprising a plurality of independently arranged blocks, the plurality of blocks are surrounded to form a material taking and dropping channel 1, the material taking and dropping channel 1 comprises a material guiding section 11 and a limiting section 12 in communication with the material guiding section 11, the material guiding section 11 gradually decreases in caliber along the direction of gradually approaching the limiting section 12, and the limiting section 12 is used to limit the position of the product relative to each block.

[0035] In the above embodiments, the material taking and dropping channel 1 is formed by surrounding a plurality of blocks, and only the surfaces forming the material guiding section 11 and the limiting section 12 need to be machined on each block during processing. The single processing surface is small, the operation space is large, the processing difficulty can be effectively reduced, and the material taking and dropping precision can be easily ensured.

[0036] It should be noted that the above product can be but is not limited to a chip.

[0037] In optional embodiments, two adjacent blocks can be spaced apart.

[0038] As Figure 1 shown, the above arrangement can form an adjustment gap 7 between two adjacent blocks, providing adjustment space for the installation position of each block, further reducing the requirement for block processing precision, easily ensuring the material taking and placing precision, and in addition, the above adjustment gap 7 can prevent the mutual extrusion between blocks due to block expansion deformation during high-temperature detection, ensuring the effective and stable use of the material placing seat.

[0039] In the translation machine test, there is a certain probability that the product is rotated and falls into the material taking and placing channel 1. In order to detect this part of the product, in optional embodiments, as Figures 1 to 3 shown, the surface of the material guiding section 11 is provided with a through groove 111 for light signal passing, and the through groove 111 is close to the groove bottom 1111 of the limiting section 12 for bearing the corner of the offset product.

[0040] In use, if the product normally falls into the limiting section 12 under the guidance of the material guiding section 11, since the bottom of the product can be accommodated in the limiting section 12, the height of the product in the material taking and placing channel 1 is low, at this time, the bottom surface of the product is lower than the groove bottom 1111, and the top surface of the product is higher than the groove bottom 1111. If the product is rotated and falls into the material guiding section 11, the position of the product is offset, and the corner of the product will be stopped from falling further under the obstruction of the groove bottom 1111, at this time, the bottom surface of the product is clamped in the material taking and placing channel 1 under the support of the groove bottom 1111, the height of the product is high, the groove bottom 1111 plays a role in lifting the height of the product, and more light signals are blocked by the product, so that the light flux of the light signal in the through groove 111 changes, thereby the product with poor positioning can be distinguished.

[0041] The groove bottom 1111 of the above-mentioned through groove 111 can be located in the material guiding section 11, or as Figure 3 shown, located in the upper part of the limiting section 12. Whether located in the material guiding section 11 or the limiting section 12, as long as the product is normally limited in the limiting section 12, the bottom surface of the product is lower than the groove bottom 1111, and the top surface of the product is higher than the groove bottom 1111.

[0042] The number of the above-mentioned through groove 111 can be selected as needed, and is usually configured in pairs, one for the light signal to enter the material taking and placing channel 1, and the other for the light signal to pass out of the material taking and placing channel 1.

[0043] In optional embodiments, as Figure 2As shown, the material guiding section 11 of each insert block is concavely provided with a through groove 111, each through groove 111 is distributed in a scattered manner relative to the material taking and dropping channel 1, and in each through groove 111, any one through groove 111 is provided with another through groove 111 which has the same extension direction, and in the two through grooves 111 which have the same extension direction, one is used for the optical signal to enter the material taking and dropping channel 1, and the other is used for the optical signal to transmit out of the material taking and dropping channel 1.

[0044] In the above embodiment, each pair of through grooves 111 which have the same extension direction can detect the deviation of the product from different directions, so that whether the product is poorly positioned can be more accurately judged.

[0045] For example Figure 2 As shown, the insert blocks are configured as four, the material guiding section 11 of each of the four insert blocks is concavely provided with a through groove 111, and two pairs of through grooves 111 which have the same extension direction are formed, one pair extends horizontally, and the other pair extends vertically, when the product is a cuboid, the above two directions can be parallel to the length and width of the product respectively, so that the product position can be more comprehensively detected.

[0046] In an optional embodiment, in order to facilitate the processing of each insert block, such as Figure 2 As shown, the plurality of insert blocks include first insert blocks 2 and second insert blocks 3 which are alternately arranged around the material taking and dropping channel 1, when the first insert blocks 2 and the second insert blocks 3 are both configured as a plurality, each first insert block 2 is centrally symmetrically distributed, and each second insert block 3 is centrally symmetrically distributed.

[0047] In the above embodiment, personnel can process the first insert blocks 2 and the second insert blocks 3 in batches, and after processing is completed, the first insert blocks 2 and the second insert blocks 3 are alternately spliced around the same axis to form the material taking and dropping channel 1, which is more convenient for the production and manufacturing of the material placing seat.

[0048] The adjacent first insert blocks 2 and the second insert blocks 3 can form an insert block unit, the insert block units are centrally symmetrically distributed, and the material placing seat can include two, three or even more insert block units, and in a preferred embodiment, as shown in the figure, Figure 2 As shown, the material placing seat includes two insert block units, that is, the first insert blocks 2 and the second insert blocks 3 are both configured as two.

[0049] In an optional embodiment, each insert block includes a main body portion and a protruding portion which is connected to the side of the main body portion, a gap for avoiding the protruding portion of the adjacent insert block is formed between the protruding portion and the main body portion, the surface shapes of the gap and the protruding portion of the adjacent two insert blocks are matched, and the protruding portions of each insert block surround to form the material taking and dropping channel 1.

[0050] The above embodiment adopts a foolproof design, when installing, the protruding portion of one insert block can be aligned with the gap of the adjacent insert block, which is convenient for splicing between the adjacent two insert blocks, and is also convenient for forming the material taking and dropping channel 1.

[0051] The following explanation uses the example of a feeding seat comprising two first inserts 2 and two second inserts 3:

[0052] like Figure 4 As shown, the first insert 2 may include a first main body 21 and a first protrusion 22, with a recessed first notch formed between the first main body 21 and the first protrusion 22; the first main body 21 has a connecting hole 4 for a connector to pass through to connect the first insert 2 to the shuttle body 6; the side of the first protrusion 22 may have a first inclined surface 221 for forming a guide section 11 and a first vertical surface 222 for forming a limiting section 12, the first inclined surface 221 and the first vertical surface 222 have a through groove 111, the through groove 111 extends vertically from the top of the first inclined surface 221 to the upper part of the first vertical surface 222, and the through groove 111 penetrates the first protrusion 22 in the horizontal direction, that is, in its own extending direction.

[0053] like Figure 5 As shown, the second insert 3 may include a second main body portion 31 and a second protrusion portion 32, with a recessed second notch formed between the second main body portion 31 and the second protrusion portion 32; the second main body portion 31 has a connecting hole 4 for a connector to pass through to connect the second insert 3 to the shuttle body 6; the side of the second protrusion portion 32 may have a second inclined surface 321 for forming a guide section 11 and a second vertical surface 322 for forming a limiting section 12, the second inclined surface 321 and the second vertical surface 322 have through grooves 111, the through grooves 111 extend vertically from the top of the second inclined surface 321 to the upper part of the second vertical surface 322, and the through grooves 111 penetrate the first protrusion portion 22 and the second main body portion 31 in the horizontal direction, that is, in its own extending direction.

[0054] like Figure 6 As shown, in an optional embodiment, the bottom surfaces of the first insert 2 and the second insert 3 are both recessed with limiting holes 5. When the first insert 2 and the second insert 3 are installed on the shuttle body 6, the limiting pin on the shuttle body 6 can pass through the limiting holes 5 to achieve the initial positioning of the first insert 2 and the second insert 3, ensuring the stability of the relative position between the first insert 2 and the second insert 3.

[0055] Specifically, such as Figure 6 As shown, there are multiple limiting holes 5, of which at least two limiting holes 5 are diagonally distributed.

[0056] The above-mentioned setting method can achieve accurate positioning of the first insert 2 and the second insert 3 in the horizontal direction through two limiting holes. After positioning, the first insert 2 and the second insert 3 can be fixedly connected to the shuttle body 6 by passing the connector through the connecting hole 4.

[0057] In a preferred embodiment, two limiting holes 5 are configured, and the two limiting holes 5 are diagonally distributed.

[0058] A second aspect of this utility model provides a feed shuttle, such as... Figures 7 to 9 As shown, the shuttle provided in the second aspect of this utility model includes a shuttle body 6 and the above-mentioned feeding seat.

[0059] The feed shuttle provided in the second aspect of this utility model has the feed seat provided in the embodiment of the first aspect of this utility model, and thus has all the beneficial effects of the feed seat provided in the embodiment of the first aspect of this utility model.

[0060] In an optional embodiment, a groove may be provided on one side of the shuttle body 6, and each insert is embedded in the groove. The shuttle body 6 has a bearing surface 62 that extends into the limiting section 12 to support the product within the limiting section 12. When the surface of the guide section 11 is recessed with a through groove 111 for the passage of light signals, the bearing surface 62 is lower than the bottom 1111 of the through groove 111, and the distance between the bearing surface 62 and the bottom 1111 is less than the thickness of the product.

[0061] The above-described implementation allows the bottom surface of the product to be lower than the bottom of the groove 1111 and the top surface of the product to be higher than the bottom of the groove 1111 after the product is normally placed on the bearing surface 62. This causes a change in the light flux within the groove 111 when the product is offset and falls onto the bottom of the groove 1111.

[0062] In alternative implementations, such as Figure 9 As shown, the shuttle body 6 has a protrusion 61 that extends into the limiting section 12, and the top surface of the protrusion 61 is the bearing surface 62.

[0063] The aforementioned protrusion 61 extends directly into the limiting section 12, which on the one hand restricts the position of each insert, and on the other hand facilitates the support of the product within the limiting section 12.

[0064] During use, it is necessary to detect in real time whether there is material in the material feeding channel 1 to monitor the material feeding situation. Therefore, in the optional implementation, such as Figure 8 and Figure 9 As shown, the shuttle body 6 has a recessed mounting groove 63 for mounting a backlight strip on the side away from the feeding seat, and the bearing surface 62 has a light-transmitting hole 621 that communicates with the mounting groove 63.

[0065] In use, when there is material in the feeding channel 1, the light emitted by the sensor above the feeding channel 1 is absorbed by the product, and the sensor does not receive enough light flux to reach the threshold, thus determining that there is material. When there is no material in the feeding channel 1, the light emitted by the sensor shines on the backlight strip through the light-transmitting hole 621. The backlight strip can reflect enough light to reach the threshold, and the sensor receives this light and determines that there is no material.

[0066] In the above embodiment, the installation groove 63 can shorten the distance between the backlight bar and the sensor, and further shorten the light signal reflection detection distance in the vertical direction, so as to quickly detect whether there is material in the material falling channel 1.

[0067] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, but not limited to them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
