Referring to fig. 1, the present utility model provides an assembling apparatus 10 and a positioning device 100. The assembly apparatus 10 includes a positioning device 100 and a carrying device 200.

The assembly apparatus 10 is used to assemble a product 20 as shown in fig. 8 and 9, the product 20 being formed by bonding two parts. For ease of distinction, the lower part will be referred to as the first part 201 and the upper part will be referred to as the second part 202. Both parts are provided with reference surfaces, a first reference surface 2011 and a second reference surface 2021, respectively. In addition, both parts are also provided with a connecting surface (not shown), and glue can be coated on the connecting surface. When the product 20 is assembled by the assembling apparatus 10, one of the parts (specifically, the first part 201) is positioned by the positioning device 100, and then the other part (specifically, the second part 202) is attached to the positioned part by the carrying device 200. After the product 20 is assembled, the connection surfaces of the two parts are connected to each other, and the first reference surface 2011 and the second reference surface 2021 are spaced apart by a predetermined dimension.

In this embodiment, the first part 201 has an oval shape, and the first reference surface 2011 has a ring shape and extends along the circumferential direction of the connection surface of the first part 201.

Referring to fig. 2 to 4, the positioning device 100 according to the preferred embodiment of the utility model includes a positioning carrier 110 and a limiting mechanism 120.

The positioning carrier 110 includes a positioning seat 111, a supporting seat 112, and an elastic member 113. The support base 112 is slidably disposed on the positioning base 111 along a first direction, which specifically refers to an up-down direction shown in fig. 3 and 4. The top end of the support base 112 has a positioning surface 1121 for carrying a part, and the part positioned by the positioning device 100, specifically, the first part 201, can be placed on the positioning surface 1121. The positioning surface 1121 is preferably planar and perpendicular to the first direction.

In the present embodiment, a channel 101 extending along a first direction is formed inside the positioning seat 111, the supporting seat 112 slidably penetrates through the channel 101, and the positioning surface 1121 and an inner wall of the channel 101 enclose a receiving portion 102 for receiving and positioning a part.

The positioning seat 111 is a hollow structure, and the supporting seat 112 is in a strip shape. The channel 101 can play a guiding role on the supporting seat 112 in the first direction, and the side wall of the channel 101 can play a better limiting role on the supporting seat 112, so that the supporting seat 112 keeps higher stability in the process of sliding along the first direction.

In the initial state, the top of the supporting seat 112 is smaller than the top of the positioning seat 111, so the supporting seat 112 is retracted in the positioning seat 111, and a concave receiving portion 102 is formed between the positioning surface 1121 and the inner wall of the channel 101. The first part 201 placed on the positioning surface 1121 is accommodated in the accommodating portion 102, and the inner wall of the accommodating portion 102 can limit the part, so that the first part 201 is prevented from sliding off the positioning surface 1121 in the process of sliding the supporting seat 112 along the first direction. The internal contour of the housing 102 matches the contour of the first component 201, and the first component 201 can be positioned.

Further, the elastic member 113 provides an elastic supporting force to the supporting seat 112 directed to the positioning surface 1121. The elastic supporting force provided by the elastic member 113 is upward as shown in fig. 4, so that the supporting seat 112 can elastically stretch and retract relative to the positioning seat 111. That is, when a downward force is applied to the supporting base 112 in the first direction, the supporting base 112 can retract with respect to the positioning base 111, and when the external force is removed, the supporting base 112 is restored to its original position by the elastic supporting force of the elastic member 113.

The elastic member 113 may be an elastic energy storage element such as a spring or a shrapnel. In the present embodiment, an annular protrusion 1111 is formed on the inner wall of the channel 101, the elastic member 113 is a compression spring sleeved on the supporting seat 112, and two ends of the compression spring respectively abut against the annular protrusion 1111 and the supporting seat 112.

Specifically, the support base 112 has a positioning surface 1121 with one end expanding to form a head (not shown) with a larger diameter, and the compression spring is sleeved on a rod (not shown) with a smaller diameter below the head, and two ends of the compression spring respectively prop against the head and the annular protrusion 1111. The diameter of the head of the support seat 112 is equal to the inner diameter of the channel 101, so that the two can be better in sliding fit, and the diameter of the rod is smaller than the inner diameter of the channel 101, so that a gap for accommodating the compression spring can be formed between the rod and the inner wall of the channel 101.

The compression spring sleeved on the supporting seat 112 is reliable in assembly and is not easy to fail after long-term use. Further, the compression springs can elastically support the support base 112 around the circumferential direction of the rod portion of the support base 112, so that the elastic support force received by the support base 112 can be more equalized.

Further, in the present embodiment, the positioning carrier 110 further includes a lock nut 114, the lock nut 114 is in threaded engagement with an end of the supporting seat 112 away from the positioning surface 1121, and an end surface of the lock nut 114 abuts against a side of the annular protrusion 1111 facing away from the compression spring.

Specifically, an external thread is formed at an end of the rod portion of the supporting seat 112 away from the positioning surface 1121, for being engaged with the lock nut 114. After the locking nut 114 is in threaded fit with the supporting seat 112, the locking nut abuts against the annular protrusion 1111, so that the supporting seat 112 can be limited, and the compression spring can be kept pre-tensioned. Further, by rotating the lock nut 114, the height of the positioning surface 1121 in the initial state can also be adjusted.

In addition, in the present embodiment, the positioning carrier 110 further includes an air connector 115, the air connector 115 is mounted on the positioning seat 111 and is communicated with the channel 101, the supporting seat 112 is provided with an air channel 103 extending to the positioning surface 1121, and the air channel 103 is communicated with the channel 101.

The air connection 115 can communicate with a negative pressure device, so that the air passage 103 can be vacuumized through the channel 101, and a negative pressure is formed on the positioning surface 1121. After the negative pressure is formed on the positioning surface 1121, the first part 201 carried on the positioning surface 1121 can be absorbed, so that the first part 201 keeps stable position on the positioning surface 1121.

Referring to fig. 2 again, the limiting mechanism 120 includes a first driving member 121 and a pressing member 122. The pressing member 122 has a pressing surface (not shown), and the first driving member 121 can drive the pressing member 122 to lift in a first direction. The first driving member 121 may be a cylinder, and the holding surface faces the positioning carrier 110 and is generally perpendicular to the first direction.

The first driving member 121 generally drives the pressing member 122 to lift in a first direction away from the positioning carrier 110, and when the first part 201 to be positioned is placed on the positioning surface 1121, the first driving member 121 can drive the pressing member 122 to descend in the first direction, so that the pressing surface abuts against the first reference surface 2011. As the hold down 122 continues to descend, the support base 112 will be forced downward in the first direction. When the first driving member 121 drives the pressing member 122 to descend to a predetermined height, the first reference surface 2011 will also be at the predetermined height. The distance that the first driving member 121 is lifted and lowered can be precisely controlled, thereby ensuring that the pressing member 122 can be driven to descend to a preset height each time. It can be seen that, whether the initial height of the first reference surface 2011 of the first part 201 is the same or not, after the effect of the limiting mechanism 120, the first reference surface 2011 will be at a preset height, so as to ensure the consistency of the height of the first reference surface 2011 in the assembly process.

In this embodiment, the limiting mechanism 120 further includes a second driving member 123, the first driving member 121 is mounted on the driving end of the second driving member 123, the pressing member 122 is mounted on the driving end of the first driving member 121, and the second driving member 123 can drive the first driving member 121 and the pressing member 122 to approach or separate from the positioning carrier 110.

The second driving member 123 may also be an air cylinder, and before the first part 201 to be positioned is placed on the positioning surface 1121, the second driving member 123 may first drive the first driving member 121 and the pressing member 122 away from the positioning carrier 110, so that the first driving member 121 and the pressing member 122 are removed from above the positioning surface 1121, thereby facilitating the first part 201 to be placed in the positioning carrier 110. After the first part 201 is placed in the positioning carrier 110, the second driving member 123 can drive the first driving member 121 and the pressing member 122 to approach the positioning carrier 110 until the pressing member 122 returns to above the positioning surface 1121.

Specifically, the second driving member 123 can drive the first driving member 121 and the pressing member 122 to move along a second direction perpendicular to the first direction, and the second direction may be a direction perpendicular to the plane of the drawing sheet or a left-right direction as shown in fig. 1.

In the present embodiment, the pressing member 122 is a pressing plate with a clearance hole (not shown) on the surface. When the pressing surface of the pressing piece 122 abuts against the first reference surface 2011, the connecting surface of the first part 201 can extend out of the avoidance hole, so that the connecting surface of the second part 202 can be conveniently attached to the connecting surface in the subsequent assembly process.

Further, in the present embodiment, the positioning device 100 further includes a first adjusting mechanism 130, the positioning carrier 110 is disposed at a rotating end of the first adjusting mechanism 130, and the first adjusting mechanism 130 can drive the positioning carrier 110 to rotate around an axis parallel to the first direction.

Since the first part 201 is oval, a specific angle is required to enable the connection surface to pass through the clearance hole of the pressing member 122 smoothly. And the angle of the first part 201 is random when it is placed on the positioning carrier 110. By driving the positioning carrier 110 to rotate around the axis parallel to the first direction, the angle of the first part 201 in the positioning carrier 110 can be adjusted, so that the connection surface of the first part 201 can smoothly pass through the avoidance hole of the pressing piece 122.

More specifically, the assembly apparatus 10 is further provided with a detection device (not shown), the detection mechanism can take a picture of the first part 201 in the positioning carrier 110 through a camera to detect a difference between the current angle of the first part 201 and the specific angle, and the first adjustment mechanism 130 can drive the positioning carrier 110 to rotate according to the difference.

After the positioning of the first part 201 is completed, the handling device 200 can obtain the second part 202 and attach the second part to the first part 201 on the positioning surface 1121, so as to complete the assembly of the product 20. Since the first reference surface 2011 of the first part 201 can be guaranteed to be at the same height during each assembly, the distance between the two first reference surfaces 201 and the second reference surface 2021 can be accurately controlled during fitting, and consistency of the product 20 can be improved.

Further, in the present embodiment, the positioning device 100 further includes a second adjusting mechanism 140, the first adjusting mechanism 130 and the limiting mechanism 120 are disposed at a rotation end of the second adjusting mechanism 140, and the second adjusting mechanism 140 can drive the first adjusting mechanism 130 and the limiting mechanism 120 to rotate around an axis perpendicular to the first direction.

The second adjustment mechanism 140 and the first adjustment mechanism 130 may each be a turntable structure driven by a servo motor. Specifically, the rotating end of the second adjusting mechanism 140 is further provided with a supporting plate 141, so as to provide a larger installation area for the first adjusting mechanism 130 and the limiting mechanism 120. When the conveying device 200 attaches the second component 202 to the first component 201, the connection surfaces of the two may be in a non-parallel state. At this time, the second adjusting mechanism 140 drives the positioning carrier 110 to rotate by driving the first adjusting mechanism 130 and the limiting mechanism 120 to rotate around the axis perpendicular to the first direction, so as to adjust the levelness of the first part 201 in the positioning carrier 110 until the connecting surface of the first part 201 is parallel to the connecting surface of the second part 202.

Furthermore, in the present embodiment, the positioning device 100 further includes a bottom plate 150 for supporting the second adjusting mechanism 140.

Referring to fig. 1 again, the transporting apparatus 200 includes a transferring mechanism 210 and an adsorbing mechanism 220. The adsorption mechanism 220 is disposed at a moving end of the transfer mechanism 210. The suction mechanism 220 is capable of sucking a part, specifically the second part 202. The transfer mechanism 210 can drive the adsorption mechanism 220 to move above the positioning carrier 110, and can drive the adsorption mechanism 220 to lift along a first direction, so that the second part 202 adsorbed by the adsorption mechanism 220 is attached to the first part 201 carried on the positioning surface 1121.

The transfer mechanism 210 drives the adsorption mechanism 220 to move to the material taking position, and the adsorption mechanism 220 sucks the second part 202. Then, the transfer mechanism 210 drives the suction mechanism 220 to move above the positioning surface 1121, and aligns the connection surface of the second component 202 with the connection surface of the first component 201. Finally, the transfer mechanism 210 drives the adsorption mechanism 220 to descend along the first direction until the connecting surface of the second part 202 is attached to the connecting surface of the first part 201.

Specifically, the transfer mechanism 210 generally includes a first transfer unit (not shown) and a second transfer unit (not shown), the suction mechanism 220 is mounted on a moving end of the first transfer unit, and the first transfer unit is mounted on a moving end of the second transfer unit. The second transferring component can drive the first transferring component and the adsorbing mechanism 220 to move along the direction perpendicular to the first direction, so as to drive the adsorbing mechanism 220 to move between the material taking position and the upper side of the positioning surface 1121, and the first transferring component can drive the adsorbing mechanism 220 to lift along the first direction.

Referring to fig. 5 and fig. 6 together, in the present embodiment, the adsorbing mechanism 220 includes a rotary driving member 221 and an adsorbing member 222, and the rotary driving member 221 can drive the adsorbing member 222 to rotate around an axis parallel to the first direction. The suction member 222 is used to suction a part, and a vacuum suction head may be used.

The rotary driving member 221 may be a motor, and an output end thereof is connected to the transmission shaft 227 through a coupling (not shown), and the adsorbing member 222 is mounted on the transmission shaft 227. The rotation driving member 221 drives the suction member 222 to rotate, and the angle of the second part 202 can be adjusted, so that the second part 202 can be attached to the first part 201 at a correct angle.

Further, in the present embodiment, the adsorption mechanism 220 further includes an adjusting plate 223 mounted on the rotating end of the rotation driving member 221, and the adsorption member 222 is detachably mounted on the adjusting plate 223. In this way, the adsorbing member 222 can be conveniently disassembled and assembled. Since the absorbent member 222 is a wearing part, abrasion may occur after a long period of use. At this time, the adsorbing member 222 needs to be replaced.

Further, in the present embodiment, the adjusting plate 223 is formed with a mounting sleeve 2231 extending in the first direction, and a positioning hole (not shown) extending in the first direction is formed at the bottom of the mounting sleeve 2231. The mounting sleeve 2231 is provided with an opening on a downward facing side for insertion of the adsorbing member 222.

The absorbing member 222 is provided with a positioning pin 2221, and the absorbing member 222 is inserted into the mounting sleeve 2231 and is positioned by matching the positioning pin 2221 with the positioning hole. In addition, the suction mechanism 220 further includes a threaded locking member 224, wherein the threaded locking member 224 retains the suction member 222 within the mounting sleeve 2231.

In mounting the absorbing member 222, the absorbing member 222 is first inserted into the mounting sleeve 2231 and the positioning pins 2221 are inserted into the positioning holes. The suction member 222 is then locked and retained within the mounting sleeve 2231 by the threaded locking member 224. The reverse operation is only necessary when removing the absorbent member 222. Therefore, only the screw locking member 224 is required to be rotated when the adsorbing member 222 is disassembled and assembled, so that the operation is more convenient.

Specifically, in the present embodiment, the outer wall of the installation sleeve 2231 is formed with an external thread, the outer wall of the absorbing member 222 is formed with a limiting step (not shown) extending along the circumferential direction, the threaded locking member 224 is a nut, an inner flange 2241 is formed at an edge of one end of the nut, the nut is in threaded engagement with the outer wall of the installation sleeve 2231, and the inner flange 2241 abuts against the limiting step. When the absorbing member 222 is installed, the nut is sleeved on the absorbing member 222 and is in threaded fit with the installation sleeve 2231, and then the threaded locking member 224 is screwed until the inner flange 2241 abuts against the limiting step.

Referring to fig. 7, in the present embodiment, the rotation end of the rotation driving member 221 is provided with a mounting plate 225, and the adsorption mechanism 220 further includes a plurality of adjusting screws 226, wherein the plurality of adjusting screws 226 penetrate the adjusting plate 223 along the first direction and are in threaded engagement with the mounting plate 225, so as to mount the adjusting plate 223 on the mounting plate 225.

Specifically, the mounting plate 225 is fixed to the end of the transmission shaft 227, and the adjustment plate 223 is mounted to the transmission shaft 227 via the mounting plate 225. By rotating the adjustment screw 226, the parallelism of the adjustment plate 223 can be adjusted. By adjusting the levelness of the adjusting plate 223, the parallelism between the suction member 222 and the second two members 202 can be adjusted, thereby ensuring that the suction member 222 can suck the second member 202 smoothly.

In the positioning device 100 and the assembling apparatus 10, when the product 20 is assembled, one of the components is placed on the positioning surface 1121 of the supporting seat 112, and then the first driving member 121 drives the pressing member 122 to descend, so that the pressing surface is abutted against the reference surface of the component carried on the positioning surface 1121. As the hold down 122 continues to descend, the support base 112 will be forced down. When the hold-down 122 is lowered to the predetermined height, the datum surface of the part will also be at the predetermined height. Then, the carrying device 200 attaches the other component to the component carried on the positioning surface 1121, thereby completing the assembly of the product 20. Under the action of the limiting mechanism 120, the reference surfaces of the parts on the positioning surface 1121 are at the same height during each assembly, so that the distance between the reference surfaces of the two parts can be accurately controlled during lamination. Therefore, the positioning device 100 and the assembling apparatus 10 can significantly improve the consistency of the product 20.
