This has high costs and low positioning accuracy. In addition, the stickiness of the double-sided tape in a high temperature environment can easily lead to difficulties in removing the board.

[0035] Please refer to Figure 1-Figure 7 , Figure 1 is a first exploded view of a thick film printing positioning tool according to one or more embodiments of the present application; Figure 2 is based on Figure 1 A second exploded view of the thick film printing positioning tooling shown; Figure 3 This is a schematic diagram of the structure of the card slot plate of the thick film printing positioning tooling in the first position according to one or more embodiments of the present application Figure 4 is a structural schematic diagram of a card slot plate of a thick film printing positioning tooling located at a second position according to one or more embodiments of the present application; Figure 5 is a schematic structural diagram of a top plate of a thick film printing positioning tool according to one or more embodiments of the present application; Figure 6 is a structural schematic diagram of a card slot plate of a thick film printing positioning tool according to one or more embodiments of the present application; Figure 7 It is a schematic structural diagram of a base plate of a thick film printing positioning tool according to one or more embodiments of the present application.

[0036] To solve the above problems, the present application provides a thick film printing positioning tool 1, including: a bottom plate 10, a top plate 20 and a slot plate 30, the top plate 20 and the bottom plate 10 are arranged relative to each other, the top plate 20 is provided with a receiving hole 21 that penetrates the two opposite surfaces of the top plate 20, and the receiving hole 21 has a positioning edge 211; the slot plate 30 is clamped between the top plate 20 and the bottom plate 10, the slot plate 30 blocks the opening of the receiving hole 21 close to the side of the bottom plate 10, and the slot plate 30 is provided with a positioning protrusion 31 protruding from the surface of the slot plate 30 on the side facing the top plate 20, the positioning protrusion 31 is correspondingly arranged in the receiving hole 21, and is arranged relative to the positioning edge 211, so that the positioning protrusion 31 and the positioning edge 211 cooperate to form a positioning space 311 for accommodating the workpiece to be positioned.

[0037] The top plate 20 and the bottom plate 10 are arranged relatively spaced apart, and the slot plate 30 is sandwiched between the top plate 20 and the bottom plate 10. Exemplarily, the bottom plate 10, the slot plate 30 and the top plate 20 can be stacked in sequence. The top plate 20 is provided with a receiving hole 21 that penetrates the opposite surfaces of the top plate 20. It can be understood that the receiving hole 21 can be used to receive the workpiece to be positioned. The slot plate 30 can block the opening of the receiving hole 21 close to the side of the bottom plate 10, thereby forming a receiving groove in cooperation with the receiving hole 21, so as to facilitate the workpiece to be positioned to be carried through the receiving groove. The positioning protrusion 31 is convexly arranged on the surface of the card slot plate 30 and is arranged in the receiving hole 21. The positioning protrusion 31 and the positioning edge 211 are arranged opposite to each other, so as to cooperate with each other to form a positioning space 311. The workpiece to be positioned can be accommodated in the positioning space 311. It can be understood that the workpiece to be positioned is located between the positioning protrusion 31 and the positioning edge 211. The positioning protrusion 31 and the positioning edge 211 can clamp the workpiece to be positioned, thereby achieving the positioning of the workpiece to be positioned. Further, after the positioning protrusion 31 and the positioning edge 211 position the workpiece to be positioned, the top plate 20 and the bottom plate 10 can also clamp the card slot plate 30, thereby reducing the risk of the card slot plate 30 being offset by the reaction force of the workpiece to be positioned, resulting in positioning failure, thereby improving the positioning stability.

[0038] Through the above-mentioned implementation, the workpiece to be positioned can be accommodated in the positioning space 311 formed by the positioning protrusion 31 and the positioning edge 211, so that the positioning protrusion 31 and the positioning edge 211 cooperate to achieve the positioning of the workpiece to be positioned, and at the same time, the top plate 20 and the bottom plate 10 can clamp the card slot plate 30. Therefore, the workpiece to be positioned is positioned by the positioning protrusion 31 and the positioning edge 211, and the bottom plate 10, the top plate 20 and the card slot plate 30 cooperate and fix with each other, thereby improving the positioning accuracy and positioning stability of the workpiece to be positioned, and at the same time, no additional consumables such as double-sided tape are required, which saves costs and improves the convenience of positioning.

[0039] In some embodiments, the slot plate 30 can move between a first position and a second position relative to the top plate 20; at the first position, the distance between the positioning protrusion 31 and the positioning edge 211 is greater than the size of the workpiece to be positioned, so that the workpiece to be positioned enters or exits the positioning space 311; at the second position, the workpiece to be positioned in the positioning space 311 abuts against the positioning protrusion 31 and the positioning edge 211 respectively, so that the positioning protrusion 31 and the positioning edge 211 fix the workpiece to be positioned. The spacing direction between the first position and the second position is the same as the spacing direction between the positioning protrusion 31 and the positioning edge 211. It can be understood that the bottom plate 10 and the top plate 20 are relatively fixed, and the slot plate 30 can move relative to the top plate 20 and the bottom plate 10. When the slot plate 30 moves between the first position and the second position, the distance between the positioning protrusion 31 on the slot plate 30 and the positioning edge 211 changes accordingly, so that the degree of clamping of the positioning protrusion 31 and the positioning edge 211 on the workpiece to be positioned in the positioning space 311 changes. Exemplarily, when the slot plate 30 is at the first position, the distance between the positioning protrusion 31 and the positioning edge 211 is greater than the size of the workpiece to be positioned, thereby providing sufficient space for the workpiece to be positioned, so that the workpiece to be positioned outside the positioning space 311 enters the positioning space 311, or the workpiece to be positioned inside the positioning space 311 exits the positioning space 311. When the slot plate 30 is at the second position, compared to the first position, the positioning protrusion 31 is closer to the positioning edge 211, so that the positioning protrusion 31 and the positioning edge 211 are simultaneously in contact with the workpiece to be positioned, so that the workpiece to be positioned is fixedly positioned under the clamping of the positioning protrusion 31 and the positioning edge 211. In some application scenarios, the second position is a position that allows the distance between the positioning protrusion 31 and the positioning edge 211 to reach a minimum value when the workpiece to be positioned is located in the positioning space 311. It is understandable that when a specific workpiece to be positioned needs to be positioned, the slot plate 30 can be first located at the first position to allow the workpiece to be positioned to enter the positioning space 311, and move to the second position after the workpiece to be positioned enters the positioning space 311 to achieve positioning of the workpiece to be positioned, and after the workpiece to be positioned is processed, the slot plate 30 moves back to the first position so that the workpiece to be positioned exits the positioning space 311. Thus, the positioning accuracy and positioning stability of the workpiece to be positioned are further improved, and at the same time, the positioning and release of the workpiece to be positioned are achieved by moving the slot plate 30 between the first position and the second position, thereby improving the flexibility and convenience of positioning.

[0040] In some embodiments, the number of the receiving holes 21 is multiple, the number of the positioning protrusions 31 is set corresponding to the number of the receiving holes 21, and the multiple receiving holes 21 are arranged on the top plate 20 at intervals, and one positioning protrusion 31 is correspondingly set in one receiving hole 21. Exemplarily, the number of the receiving holes 21 can be one, two, three or more, and correspondingly, the number of the positioning protrusions 31 can also be one, two, three or more. One positioning protrusion 31 corresponds to one receiving hole 21, so that one positioning protrusion 31 cooperates with one positioning edge 211. It can be understood that in some embodiments, one positioning protrusion 31 and one positioning edge 211 can position one workpiece to be positioned. As a result, multiple receiving holes 21 and multiple positioning protrusions 31 can simultaneously position multiple workpieces to be positioned, thereby greatly improving the positioning and processing efficiency of the workpieces to be positioned.

[0041] In some embodiments, the plurality of accommodating holes 21 are arranged in an array. The arrangement of the plurality of accommodating holes 21 may include, but are not limited to, a matrix array, a circular array, a triangular array, a honeycomb array, a spiral array, and the like. For example, the plurality of accommodating holes 21 may be arranged in a matrix array, and the number of accommodating holes 21 is sixty-three, which are evenly arranged on the top plate 20 in the form of nine rows and seven columns. Correspondingly, the plurality of positioning protrusions 31 may also be evenly arranged on the card slot plate 30 in a corresponding form. In this way, the distribution of the plurality of accommodating holes 21 can be made more evenly and reasonably, reducing the molding difficulty of the positioning tooling, and the plurality of accommodating holes 21 arranged in an array can further improve the glue discharge efficiency of the positioning tooling.

[0042] In some embodiments, a guide column 33 is provided on one side of the card slot plate 30 facing the bottom plate 10, and the bottom plate 10 is provided with a guide groove 12 that is recessed relative to the card slot plate 30. The guide column 33 is inserted into the guide groove 12 and can slide in the guide groove 12 to move the card slot plate 30 between the first position and the second position. It can be understood that when the card slot plate 30 moves between the first position and the second position, the guide column 33 can slide in the guide groove 12, thereby providing a guiding effect for the card slot plate 30, reducing the risk of deviation when the card slot plate 30 moves.

[0043] In some embodiments, the base plate 10 is provided with a first fastening hole 13 in the first direction x1 where the positioning protrusion 31 and the positioning edge 211 are arranged, and the first fastening hole 13 is connected to the guide groove 12. The thick film printing positioning tool 1 also includes a first fastener. At the second position, the first fastener is inserted into the first fastening hole 13 and the guide groove 12, and contacts the guide column 33. The opening direction of the first fastening hole 13 is the same as the first direction x1, so that the first fastener can be inserted into the first fastening hole 13 and the guide groove 12 along the first direction x1, and the first fastener contacts the guide column 33 in the guide groove 12, thereby fastening the card slot plate 30, improving the stability of the card slot plate 30 when it is in the second position, and reducing the risk of positioning failure caused by the card slot plate 30 deviating from the second position. Among them, the first fastener may include but is not limited to bolts, etc. In some application scenarios, the number of guide columns 33, guide grooves 12, first fastening holes 13 and first fasteners may correspond to multiple, and optionally, may be two.

[0044] In some embodiments, the guide groove 12 includes a first groove section 121 and a second groove section 122 that are connected to each other, the first groove section 121 extends along a first direction x1, the second groove section 122 extends along a second direction x2 that is perpendicular to the first direction x1, and the first fastening hole 13, the second groove section 122 and the first groove section 121 are connected in sequence. The first fastener can be inserted into the first fastening hole 13, the second groove section 122 and the first groove section 121 in sequence, and the second groove section 122 extends along the second direction x2, so that the guide groove 12 is connected to the first fastening hole 13, so that the first fastener can be more conveniently inserted into the guide groove 12. In some application scenarios, the thick film printing positioning tooling 1 may also include a slider, the shape of which may match the shape of the second slot segment 122, the slider may be arranged in the second slot segment 122, the slider may be provided with a fourth fastening hole that runs through the surfaces of both sides of the slider, the first fastening hole 13, the fourth fastening hole, and the first slot segment 121 are connected in sequence, so as to facilitate the insertion of the first fastener through the first fastening hole 13, the fourth fastening hole, and the first slot segment 121, wherein the slider may be replaced as a consumable part, and the first fastener may be fastened in conjunction with the fourth fastening hole. It should be noted that, compared with the first fastener being directly inserted into the first fastening hole 13, the first fastener is also inserted into the fourth fastening hole of the slider at the same time, which can improve the fastening stability of the first fastener, and the slider is a consumable part, which is convenient for replacing the slider when the connection effect between the first fastener and the fourth fastening hole decreases, for example, when the internal thread of the fourth fastening hole is worn, thereby reducing the risk of damage to non-consumable parts that are difficult to replace due to frequent disassembly and assembly of the first fastener, such as the connection between the base plate 10 body and the first fastener.

[0045] In some embodiments, the base plate 10 is provided with an avoidance groove 14 at the end away from the first fastening hole 13, the notch of the avoidance groove 14 is facing the first direction x1, and the bottom wall of the avoidance groove 14 is provided with a second fastening hole 15; the card slot plate 30 is provided with a fastening portion 34 on the side facing the base plate 10, the fastening portion 34 is arranged corresponding to the avoidance groove 14, and the fastening portion 34 is provided with a third fastening hole 35, and the third fastening hole 35 is connected to the second fastening hole 15. The thick film printing positioning tooling 1 also includes a second fastener, and at the second position, the second fastener is inserted into the third fastening hole 35 and the second fastening hole 15. The fastening portion 34 can be protruded from the side surface of the slot plate 30 facing the base plate 10, and the avoidance groove 14 can be used to avoid the fastening portion 34. It can be understood that the second fastener can be inserted into the third fastening hole 35 and the second fastening hole 15 in sequence, so as to connect the slot plate 30 and the base plate 10, and the slot plate 30 can be fastened by the second fastener in the first direction x1, thereby further improving the fastening effect of the slot plate 30, thereby reducing the risk of positioning failure caused by the offset of the slot plate 30 at the second position.

[0046] In some embodiments, the thick film printing positioning tool 1 further includes a fixing member, the bottom plate 10 is provided with a first fixing hole 11, the card slot plate 30 is provided with a guide hole 32, and the top plate 20 is provided with a second fixing hole 22. The first fixing hole 11, the guide hole 32 and the second fixing hole 22 are connected in sequence. At the second position, the fixing member is inserted into the first fixing hole 11, the guide hole 32 and the second fixing hole 22. The fixing member may include but is not limited to a bolt, a latch, etc. The fixing member may be inserted into the first fixing hole 11, the guide hole 32 and the second fixing hole 22, so that the top plate 20 and the bottom plate 10 are relatively fixed, and the pressure of the top plate 20 and the bottom plate 10 clamping the card slot plate 30 may be increased, thereby improving the stability of the card slot plate 30. In some application scenarios, the guide hole 32 may extend along the first direction x1, so that the fixing member may slide in the guide hole 32, so that the card slot plate 30 moves between the first position and the second position. It is understandable that when the card slot plate 30 is in the first position, the fixing member may also be inserted into the first fixing hole 11. In the guide hole 32 and the second fixing hole 22 , the fastening degree of the fixing member can be lower than when the slot plate 30 is located at the second position, so as to facilitate the movement of the slot plate 30 to the second position.

[0047] In some embodiments, the positioning protrusion 31 is located between two opposite surfaces of the top plate 20 , and the distance between the side surface of the positioning protrusion 31 facing away from the bottom plate 10 and the side surface of the top plate 20 facing away from the card slot plate 30 is greater than or equal to 0.5 mm. In some application scenarios, when the workpiece to be positioned is positioned in the positioning space 311 by the positioning protrusion 31 and the positioning edge 211, and the thick film printing positioning tool 1 is in a fastened state, the side surface of the workpiece to be positioned away from the card slot plate 30 is located in the receiving hole. It can be understood that the side surface of the workpiece to be positioned away from the card slot plate 30 can be lower than the side surface of the top plate 20 away from the card slot plate 30 or flush with the side surface of the top plate 20 away from the card slot plate 30. For example, when the side surface of the workpiece to be positioned away from the card slot plate 30 is substantially flush with the side surface of the top plate 20 away from the card slot plate 30, the distance between the side surface of the positioning protrusion 31 away from the bottom plate 10 and the side surface of the workpiece to be positioned away from the card slot plate 30 can also be greater than or equal to 0.5 mm. As a result, the risk of interference between the processing equipment and the side surface of the positioning protrusion 31 away from the bottom plate 10 when entering the receiving hole 21 when processing the workpiece to be positioned is reduced, thereby improving the safety and reliability of the thick film printing positioning tool 1.

[0048] In summary, the present application provides a thick film printing positioning tool 1, and the workpiece to be positioned can be accommodated in the positioning space 311 formed by the positioning protrusion 31 and the positioning edge 211, so that the positioning protrusion 31 and the positioning edge 211 cooperate to achieve the positioning of the workpiece to be positioned, and the top plate 20 and the bottom plate 10 can clamp the card slot plate 30. Thus, the workpiece to be positioned is positioned by the positioning protrusion 31 and the positioning edge 211, and the bottom plate 10, the top plate 20 and the card slot plate 30 cooperate and fix with each other, thereby improving the positioning accuracy and positioning stability of the workpiece to be positioned, and at the same time, there is no need to use additional consumables such as double-sided tape, saving costs and improving positioning convenience. Compared with other thick film printing positioning tools, the thick film printing positioning tool 1 provided by the present application is more flexible in positioning and has lower costs.
