[0035] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0036] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0038] According to one embodiment of this application, a positioning fixture is provided for attaching pads to adhesive strips. The positioning fixture includes an operating table 1, a measuring unit 3, a guide 4, a sliding member 5, and a positioning member 6. The operating table 1 has a placement area 2 for placing the adhesive strip, the placement area 2 extending along a predetermined direction. The measuring unit 3 is disposed on the operating table 1, and the extension direction of the measuring unit 3 is parallel to the extension direction of the placement area 2. The guide 4 is disposed on the operating table 1, and the extension direction of the guide 4 is parallel to the extension direction of the placement area 2. The extension direction of the measuring unit 3; the sliding member 5 is slidably disposed on the guide member 4; the positioning member 6 is connected to the sliding member 5; wherein, the positioning member 6 has a first state and a second state, and based on the movable connection between the positioning member 6 and the sliding member 5, the positioning member 6 switches between the first state and the second state. In the first state, the positioning member 6 is in the placement area 2 and corresponds to the position to be pasted on the adhesive strip. In the second state, the positioning member 6 is separated from the adhesive strip and is used to cooperate with the sliding member 5 to perform linear reciprocating motion.

[0039] like Figures 1 to 3 As shown, the workbench 1 has a rectangular surface, and the measuring unit 3 extends along the length of the workbench 1. The adhesive strip is long and its length is laid along the length of the workbench 1, with one end of the adhesive strip aligned with the measuring line of the measuring unit 3 to facilitate quick measurement of the position where the adhesive strip is to be pasted.

[0040] Of course, the adhesive tape in the embodiments of the present application is not limited to the above structure, and those skilled in the art can set it according to actual needs. For example, the adhesive tape can also be polygonal, elliptical or the like, and the extension direction of the two to-be-pasted positions of the adhesive tape is parallel to the extension direction of the measuring unit 3 and is laid on the operation table 1, so as to facilitate the measurement of the spacing of the plurality of to-be-pasted positions on the adhesive tape by the measuring unit 3.

[0041] The sliding piece 5 is slidingly arranged on the guide piece 4, and the sliding piece 5 is connected with the positioning piece 6. The positioning piece 6 is driven to move along the extension direction of the guide piece 4 by sliding the sliding piece 5 along the guide piece 4, and the relative position between the positioning piece 6 and the adhesive tape is adjusted by adjusting the position of the sliding piece 5 on the guide piece 4.

[0042] The to-be-pasted position on the adhesive tape is measured by the measuring unit 3, and then the sliding block is moved to drive the positioning piece 6 to move to the position corresponding to the to-be-pasted position, so that the positioning piece 6 positions the to-be-pasted position on the adhesive tape to mark the to-be-pasted position of the adhesive tape. This not only reduces the labor intensity of manual measurement and marking and improves the measurement accuracy, but also facilitates the accurate identification of the to-be-pasted position by the operator or the operating equipment, so that the cushion block can be quickly and accurately pasted on the preset position of the adhesive tape, and the pasting efficiency of the cushion block is effectively improved.

[0043] The positioning piece 6 is movably connected with the sliding piece 5, and the movable connection can be rotary connection or telescopic connection. As long as the positioning piece 6 can realize the marking function of the to-be-pasted position of the adhesive tape, it belongs to the protection scope of the present application.

[0044] The positioning piece 6 is plate-shaped, and the sliding piece 5 is rectangular block-shaped. One end of the plate-shaped positioning piece 6 is rotatably connected with one side of the sliding piece 5 through a hinge. When it is needed to mark the adhesive tape, the positioning piece 6 is switched to the first state, that is, the positioning piece 6 is rotated clockwise, so that the included angle between the positioning piece 6 and the sliding piece 5 is increased, and the positioning piece 6 corresponds to the to-be-pasted position of the adhesive tape, so as to position and mark the to-be-pasted position of the adhesive tape. When it is needed to take out or place a new adhesive tape, the positioning piece 6 is switched to the second state, that is, the positioning piece 6 is rotated counterclockwise, so that the included angle between the positioning piece 6 and the sliding piece 5 is reduced, and the positioning piece 6 is away from the placement area 2, so as to avoid the adhesive tape and facilitate the taking or placing of the new adhesive tape.

[0045] Of course, the positioning piece 6 and the sliding piece 5 in the embodiments of the present application are not limited to the above structure, and those skilled in the art can set them according to actual needs.

[0046] For example, after the position of the rubber strip to be pasted is measured, the positioning member 6 is stretched, i.e., the positioning member 6 is in the first state, so that the positioning member 6 embedded in the sliding member 5 extends to the placement area 2 and corresponds to the position of the rubber strip to be pasted to mark the position of the rubber strip to be pasted. When the rubber strip pasting is completed and the rubber strip without the pad is taken out or placed, the positioning member 6 is embedded into the sliding member 5, i.e., the positioning member 6 is in the second state, so that the positioning member 6 is avoided to facilitate the taking or placing of the rubber strip, and by placing the positioning member 6 in the second state, it is also beneficial to the movement of the sliding member 5 along the guide 4, reducing the interference of the positioning member 6 with the position adjustment of the sliding member 5.

[0047] The positioning member 6 is driven by the sliding member 5 to move linearly along the guide 4 to adjust the relative position of the positioning member 6 and the rubber strip, so that the positioning member 6 can correspond to the position of the rubber strip to be pasted to mark the position of the rubber strip to be pasted, so that the operator or operating equipment can quickly identify the marked position to speed up the pasting of the pad and thereby improve production efficiency.

[0048] In the embodiment of the present application, the rubber strip to be pasted with the pad is arranged on the operation table 1 in the first direction, and one end of the rubber strip corresponds to the measuring unit 3, which is used to measure the position of the rubber strip to be pasted. The positioning assembly is moved along the first direction by the guide structure, and the positioning assembly is moved to the position of the rubber strip to be pasted corresponding to the measuring unit 3. The positioning member 6 is rotated to be in the first state, and the positioning member 6 is parallel to the first direction to position the position of the rubber strip to be pasted. After the pasting of the pad is completed, the positioning member 6 is rotated to be in the second state, and the positioning member 6 is perpendicular to the first direction to take out the pasted rubber strip or place a new rubber strip to be pasted with the pad.

[0049] From the above, the measuring unit 3 is used to measure the rubber strip to quickly determine the position to be pasted, and the positioning assembly can move along the first direction by the guide structure to move the positioning member 6 to the position to be pasted, effectively improving the marking speed of the position to be pasted. Moreover, the positioning member 6 is rotationally connected with the connecting member, so that the positioning member 6 can be switched between the first state and the second state. Not only can the marking speed of the position to be pasted be effectively improved in the first state, but also the positioning tool can be adapted to rubber strips with different pasting intervals in the second state by moving along the first direction with the guide structure, effectively improving the adaptability of the positioning tool.

[0050] In addition, the rubber strip is measured by the measuring unit 3, and the position to be pasted is marked by the positioning member 6, effectively reducing the labor intensity and complexity, reducing the errors caused by environmental changes or operational negligence in manual measurement and marking, and improving the pasting accuracy and efficiency.

[0051] In one example, the connecting piece is provided with a locking piece 51, one end of the locking piece 51 penetrates the sliding piece 5 and abuts against the guide piece 4, and the locking piece 51 is used to lock the sliding piece 5.

[0052] As shown in Figures 1 to 3 , the sliding piece 5 is in the shape of a rectangular block, and the locking piece 51 is arranged on the sliding piece 5, the locking piece 51 is a bolt, the top end of the bolt penetrates the sliding piece 5 and faces the guide piece 4. When the sliding piece 5 needs to drive the positioning piece 6 to move, the bolt is loosened, so that the sliding piece 5 can move along the guide piece 4, and when the positioning piece 6 is driven by the sliding piece 5 to move to the position to be pasted with the adhesive tape, the bolt is turned, so that the top of the bolt abuts against the guide piece 4, thereby fixing the sliding block on the guide piece 4, preventing the positioning piece 6 from moving along with the sliding piece 5 on the guide piece 4 during the positioning and pasting of the cushion block, and causing inaccurate positioning.

[0053] By arranging the locking piece 51, the positioning piece 6 can be driven to move along the guide piece 4 by the sliding piece 5, and the positioning piece 6 can be fixed on the guide piece 4 by the locking piece 51, preventing the sliding piece 5 from moving, and effectively improving the positioning accuracy.

[0054] Of course, the locking piece 51 in the embodiments of the present application is not limited to the above structure, and those skilled in the art can arrange it according to actual needs. For example, the locking piece 51 can also be connected with the sliding piece 5 in the form of buckling, fitting, etc.

[0055] In one example, the guide piece 4 is sequentially provided with a plurality of sliding pieces 5, and the arrangement direction of the plurality of sliding pieces 5 is parallel to the extension direction of the measuring unit 3.

[0056] As shown in Figures 1 to 3 , the guide piece 4 is provided with a plurality of sliding pieces 5, so as to facilitate positioning and marking of a plurality of positions of the adhesive tape, and effectively improve the adaptability of the positioning tool.

[0057] In one example, the guide piece 4 is provided with a guide groove 41, the extension direction of the guide groove 41 is parallel to the extension direction of the measuring unit 3, and a plurality of sliding pieces 5 are slidingly arranged in the guide groove 41.

[0058] As shown in Figures 1 to 3 , the guide piece 4 is a slide rail, and the slide rail is provided with a guide groove 41. A plurality of sliding pieces 5 are arranged in the guide groove 41 in parallel to the extension direction of the placement area 2, so that the plurality of sliding pieces 5 can position and mark a plurality of positions to be pasted with the adhesive tape, and effectively improve the work efficiency.

[0059] Of course, the guide piece 4 in the embodiments of the present application is not limited to the above structure, and those skilled in the art can arrange it according to actual needs. For example, the guide piece 4 can also be a slide rod.

[0060] In one example, the guide 4 is a slide bar, the extension direction of the slide bar is parallel to the extension direction of the measuring unit 3, and the slide 5 is a slide block matched with the slide bar, and a plurality of slides 5 can move linearly and reciprocally on the slide bar along the preset direction.

[0061] In the embodiment of the application, the guide 4 is a slide bar, and the slide bar is parallel to the extension direction of the placement area 2.

[0062] The slide bar is prismatic, a through hole matched with the prism is formed in the slide 5, the slide 5 is sleeved on the slide bar through the through hole, and the slide 5 can move along the length direction of the slide bar. By arranging a plurality of slides 5 on the slide bar, the plurality of slides 5 can mark the plurality of positions to be pasted of the adhesive tape, and the working efficiency is effectively improved.

[0063] In one example, the operating table 1 is provided with a limiting part, the extension direction of the limiting part is parallel to the extension direction of the placement area 2, and when the adhesive tape is located on the placement area 2, the side wall of the adhesive tape abuts against one side of the limiting part perpendicular to the extension direction of the placement area 2.

[0064] As shown in Figures 1 to 3 The limiting part on the operating table 1 is used for supporting the adhesive tape, so that the adhesive tape can be laid along the extension direction. For example, the adhesive tape with a bending part is bent on the placement area 2 when laid, and cannot be unfolded along the extension direction of the measuring unit 3, which affects the measurement accuracy. By supporting the adhesive tape through the limiting part, the adhesive tape can be stretched and laid along the extension direction of the measuring unit 3, so as to facilitate the accurate measurement of the position to be pasted of the adhesive tape, and improve the measurement and marking accuracy.

[0065] In one example, the limiting part is a limiting groove 7, and the extension direction of the limiting groove 7 is parallel to the extension direction of the measuring unit 3.

[0066] As shown in Figures 1 to 3 The limiting part is a limiting groove 7 formed on the operating table 1. The limiting groove 7 is formed along the extension direction of the measuring unit 3. The adhesive tape to be pasted can be placed in the limiting groove 7, and the position of the adhesive tape on the operating table 1 is fixed through the limiting groove 7, so as to prevent the adhesive tape from moving or being bent and deformed during the measurement, marking and pasting, and affect the pasting quality.

[0067] The measuring unit 3 can be arranged in the limiting groove 7 or on the operating table 1.

[0068] According to the thickness of the adhesive tape to be pasted with the cushion block, the limiting recess 7 with different heights can be arranged. When the limiting recess 7 is deep and the thickness of the adhesive tape to be pasted with the cushion block is small, a compensation part such as a square tube, a pad plate or the like can be placed in the limiting recess 7 to improve the position of the adhesive tape in the limiting recess 7, so that the positioning part 6 can mark the position to be pasted of the adhesive tape.

[0069] In one example, the limiting part is a limiting protrusion 8 arranged on the operation table 1, the extending direction of the limiting protrusion 8 is parallel to the extending direction of the placing area 2, the limiting protrusion 8 is parallel to the guide part 4 along the preset direction; wherein the adhesive tape is arranged between the limiting protrusion 8 and the guide part 4.

[0070] As shown in Figures 1 to 3 , the limiting part is a limiting protrusion 8 arranged on the operation table 1. The limiting protrusion 8 is arranged along the extending direction of the measuring unit 3. The limiting protrusion 8 and the guide part 4 are arranged on the two opposite sides of the placing area 2, that is, the adhesive tape is placed between the guide part 4 and the limiting protrusion 8. The position of the adhesive tape on the operation table 1 is fixed by the limiting protrusion 8, so that the adhesive tape is prevented from moving or being deformed in the measuring, marking and pasting processes, and the pasting quality is affected.

[0071] The measuring unit 3 can be arranged on the limiting protrusion 8 or in the placing area 2 of the operation table 1.

[0073] As shown in Figures 1 to 3 , the measuring unit 3 can be a scale line or a scale ruler. In the embodiment of the application, the measuring unit 3 is a steel ruler. When the adhesive tape needs to be pasted with the cushion block, the adhesive tape to be pasted is placed in the placing area 2 of the limiting recess 7, and one end of the adhesive tape is aligned with the scale of the steel ruler. The adhesive tape is held by the side wall of the limiting recess 7 to prevent the adhesive tape from moving or being deformed in the measuring and marking processes. The sliding part 5 is moved according to the marking line on the steel ruler, so that the sliding part 5 drives the positioning part 6 to move to the position of the preset marking line. The sliding part 5 is locked by the locking part 51 and fixed on the guide part 4. The positioning part 6 is rotated, so that the positioning part 6 is flipped and corresponds to the position to be pasted of the adhesive tape. Then the cushion block can be pasted on the adhesive tape at the position of the positioning part 6. After the pasting is completed, the positioning part 6 is rotated in the reverse direction to move away from the adhesive tape, so that the new adhesive tape can be taken or placed, and the sliding part 5 can be moved along the guide part 4 to adapt to the adhesive tape with different spacing cushion block requirements.

[0074] According to another embodiment of the present application, a rubber strip production line is provided, which comprises a rubber strip and the positioning tool as described above, the rubber strip is located in the placement area 2, and the rubber strip is arranged along the preset direction.

[0075] In the embodiment of the present application, the rubber strip to which the cushion block needs to be pasted is laid in the placement area 2, and one end of the rubber strip is aligned with the mark line of the measuring unit 3, so as to measure the position to be pasted of the rubber strip. After the rubber strip is arranged, the sliding member 5 is moved on the guide member 4, so that the positioning member 6 on the sliding member 5 corresponds to the position to be pasted of the rubber strip. After the sliding member 5 is moved to the preset position, the locking member 51 is rotated to fix the sliding member 5 on the guide member 4, so as to prevent the sliding member 5 from moving and affecting the marking accuracy during the measuring and marking process. The positioning member 6 is rotated or stretched, so that the positioning member 6 corresponds to the position to be pasted of the rubber strip, so as to enable the operator or the operating device to quickly identify the position, so as to accurately paste the cushion block on the position to be pasted of the rubber strip. When the pasting is completed and the new rubber strip needs to be taken out or put in, the positioning member 6 is reversely rotated or contracted, and the locking member 51 is loosened, so that the sliding member 5 drives the positioning member 6 to move away from the placement area 2, so as to avoid the rubber strip. Not only can the new rubber strip be conveniently taken out or put in, but also the positioning member 6 can move in cooperation with the sliding member 5, so as to adapt to the rubber strip with different interval cushion block positions, and the adaptability of the positioning tool is effectively improved.
