[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] See Figure 1-9 A pick and place machine, a pick and place machine, having:

[0048] The system includes: a frame; a base plate mounted on the frame; a strain gauge separation device mounted on the base plate, capable of separating strain gauges; a rotating mechanism rotatably mounted on the base plate; a positioning mechanism, with at least two sets of positioning mechanisms on the rotating mechanism, capable of positioning the sensor elastomer; and a robotic arm mounted on the base plate, capable of picking up strain gauges and attaching them to the sensor elastomer.

[0049] Positioning mechanisms include:

[0050] A first slide cylinder; a first slider and a second slider, slidably mounted on the first slide cylinder; the first slider and the second slider can slide under the drive of the first slide cylinder.

[0051] A column is located near the middle of the first slide cylinder; a support block is mounted on the column; a groove is located on the support block, and the sensor elastomer can be placed in the groove, the size of the groove being larger than the size of the sensor elastomer; the support block and the groove serve to place the sensor elastomer.

[0052] The first positioning block is mounted on the first slider; the first positioning block can slide under the action of the first slider.

[0053] The second slide cylinder is mounted on the second slider; two second positioning blocks are mounted on the two slide plates of the second slide cylinder; the two second positioning blocks can slide under the drive of the second slide cylinder, and the sides of the first and second positioning blocks can cooperate to clamp the sensor elastic body inside the support block; under the drive of the first and second sliders, the sides of the first and second positioning blocks can clamp the sides of the sensor elastic body, thereby achieving X-axis positioning.

[0054] Two locking blocks are respectively mounted on two second positioning blocks; each locking block can be adapted to both sides of the inner hole of the sensor elastomer. The second slide cylinder drives the two locking blocks to move, inserting them into the inner hole of the sensor elastomer, and then moving them outward to adapt to both sides of the inner hole of the sensor elastomer, thereby achieving Y-axis positioning. After X-axis and Y-axis positioning are completed, Z-axis positioning of the bottom edge of the groove is added to complete the positioning of the sensor elastomer. After positioning is completed, the patching process can begin.

[0055] The clamping and positioning on both sides and the positioning on both sides of the inner hole can adapt to the positioning of different types of sensor elastomers without the need to change the positioning mechanism, resulting in high work efficiency.

[0056] The support block and its cross-section are "I"-shaped; the width of the middle part of the sensor elastic body is greater than the width of the middle part of the support block. This ensures that the middle part of the support block does not exceed the middle part of the sensor elastic body, allowing it to be clamped to the middle part of the sensor elastic body without clamping the middle part of the support block.

[0057] The first positioning block has positioning rubber wheels on its positioning surface. The second positioning block also has positioning rubber wheels on its positioning surface. This serves a protective function during positioning.

[0058] The positioning surface of the card block is curved, which makes it easy to fit the inner hole.

[0059] The first slide cylinder is equipped with a slide rail, a first slider and a second slider, which are slidably installed inside the slide rail.

[0060] It also has a mounting plate, which is mounted on the second slider, and the second slide cylinder is mounted on the mounting plate.

[0061] It also has a base, which is located on the first end of the first slide cylinder and covers the first positioning block. The base protects the first positioning block.

[0062] The first positioning block has a "T" shaped cross-section, and a set of positioning rubber wheels is provided on each side of the upper end of the first positioning block. The symmetrical arrangement makes the clamping and positioning more stable.

[0063] In use, the two second positioning blocks slide under the drive of the second slide cylinder. The sides of the first and second positioning blocks cooperate to clamp the sensor elastomer inside the support block to achieve X-axis positioning. The second slide cylinder drives the two clamping blocks to move. The two clamping blocks are inserted into the inner hole of the sensor elastomer. Then the two clamping blocks move outward to adapt to the two sides of the inner hole of the sensor elastomer, thereby achieving Y-axis positioning. After positioning is completed, the patching robot clamps the strain gauge and pastes it onto the surface of the sensor elastomer.

[0064] The clamping and positioning on both sides and the positioning on both sides of the inner hole can adapt to the positioning requirements of sensor elastomers of different specifications, without the need to replace the positioning mechanism, resulting in high work efficiency.

[0065] The strain gauge separation device has:

[0066] The material distribution box is installed on the base plate; the material distribution box is used to put materials, and multiple strain gauges stacked together are placed in the material distribution box.

[0067] Side air vents are located on the sides of the distribution box; these vents allow air to be blown onto the sides of the distribution box. Bottom air vents are located at the bottom of the distribution box; these vents allow air to be blown onto the bottom of the distribution box. With air vents on both the bottom and sides, compressed air is used to blow the strain gauges inside the distribution box, causing the stacked strain gauges to separate.

[0068] The cover plate is movably mounted on the base plate. During the movement of the cover plate, it can cover the upper part of the distribution box. When blowing air through the small hole at the bottom, the distribution box needs to be covered to prevent the strain gauges inside the distribution box from flying out.

[0069] The cover plate drive mechanism is capable of driving the cover plate to move. The cover plate drive mechanism includes a cover plate slider cylinder, which is mounted on the base plate, and the cover plate slider of the cover plate slider cylinder is connected to the cover plate. The cover plate is driven to move by the cover plate slider cylinder.

[0070] It also features an air blowing plate, which is located near the center of the distribution box and has air blowing holes. The bottom air blowing hole is located below the air blowing plate. Strain gauges are stacked on the air blowing plate, and the bottom air blowing hole blows air towards the bottom of the distribution box. The gas at the bottom of the distribution box is blown upward through the air blowing hole on the air blowing plate and acts on the bottom of the strain gauges.

[0071] It also features a feeding hopper, which is mounted on the frame, with the feeding end of the hopper located above the distribution box. Strain gauges are fed into the distribution box through the feeding hopper.

[0072] The base plate is also equipped with a material box to accommodate the strain gauge, which serves to hold the material.

[0073] The cover plate has a series of vent holes, so that when the cover plate covers the distribution box, other materials blown out of the distribution box can be discharged through the vent holes.

[0074] The dispensing box is square, and there are side air blowing holes on all four sides of the dispensing box to ensure even air blowing.

[0075] Strain gauges are fed into the distribution box through a hopper. There are air vents on the bottom and sides, and compressed air is used to blow compressed air into the strain gauges in the distribution box, causing the stacked strain gauges to separate.

[0076] It can separate multiple stacked strain gauges, preventing them from sticking together during the robotic arm's gripping process. When blowing air, the distribution box needs to be covered to prevent the strain gauges inside from flying out.

[0077] The rotating mechanism includes a rotary motor and a rotary disk. The rotary motor is mounted on the base plate, and the rotary disk is connected to the rotating shaft of the rotary motor. The positioning mechanism is mounted on the rotary disk. After the workpiece is placed, it is sent out through the rotating mechanism. The workpiece is then removed, and an unplaced workpiece is placed in, and the process is repeated by rotating again.

[0078] With the above structure, it can adapt to the positioning requirements of sensor elastomers of different specifications, automatically complete the patching work, and achieve high work efficiency.

[0079] In the description of this invention, it should be understood that the terms "coaxial," "bottom," "one end," "top," "middle," "other end," "upper," "side," "top," "inner," "front," "center," "both ends," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0080] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," "fixing," "screw connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components.
