[0048] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0049] See also Figure 1-Figure 10The embodiment of the utility model provides a PCM board positioning device, including a workbench 1 and a positioning mechanism 2. The workbench 1 is provided with a discharge position 11. The positioning mechanism 2 includes a support portion 21, a positioning assembly 22 and a push assembly 23. The support portion 21 is provided at the discharge position 11 and is connected to the workbench 1, and is used to support a workpiece 5, which is a PCM board; the positioning assembly 22 includes a first positioning block 221, a second positioning block 222, a third positioning block 223 and a transmission assembly 224, and the transmission assembly 224 is elastically connected to the workbench 1. The first positioning block 221 and the second positioning block 222 are spaced apart on both sides of the support portion 21 along the first direction X and are elastically connected to the transmission assembly 224. The first positioning block 221 and the second positioning block 222 are respectively used to clamp and position the two ends of the workpiece 5; the third positioning block 223 is provided at the discharge position 11, and the third positioning block 223 is provided at the discharge position 11. 23 is slidably assembled on the workbench 1 and elastically connected to the workbench 1, and the third positioning block 223 is spaced apart from the support portion 21 along the second direction Y; the pushing assembly 23 is spaced apart from the positioning assembly 22, and the pushing assembly 23 pushes the transmission assembly 224 and the third positioning block 223 to make the transmission assembly 224 away from the workbench 1 along the third direction Z, and the first positioning block 221 and the second positioning block 222 away from each other along the first direction X, and the third positioning block 223 away from the support portion 21 along the second direction Y, so that the first positioning block 221, the second positioning block 222 and the third positioning block 223 are all away from the support portion 21, which is convenient for placing the workpiece on the support portion 21 or taking out the workpiece on the support portion 21. When the pushing assembly 23 moves away from the transmission assembly 224 and the third positioning block 223, the transmission assembly 224 is reset along the third direction Z close to the workbench 1; the first positioning block 221 and the second positioning block 222 are reset along the first direction X close to each other; the third positioning block 223 is reset along the second direction Y close to the support part 21, so that the first positioning block 221, the second positioning block 222 and the third positioning block 223 are all reset to the state of clamping the workpiece 5.

[0050] When the transmission assembly 224 is pushed, the first positioning block 221 and the second positioning block 222 are moved away from each other along the first direction X, and the transmission assembly 224 is moved away from the workbench 1 along the third direction Z. When the transmission assembly 224 moves along the third direction Z, the first positioning block 221 and the second positioning block 222 are driven to move away from the support portion 21 synchronously along the third direction Z. When the transmission assembly 224 is pushed, the third positioning block 223 is also moved away from the support portion 21 along the second direction Y. Therefore, one pushing movement of the pushing assembly 23 can make the first positioning block 221, the second positioning block 222 and the third positioning block 223 all move away from the support portion 21, avoiding the position where the workpiece 5 is placed on the support portion 21, so as to facilitate the placement of the workpiece 5 on the support portion 21 or the removal of the workpiece 5 on the support portion 21. When the push assembly 23 moves away from the transmission assembly 224 and the third positioning block 223 in the reverse direction, the transmission assembly 224, the first positioning block 221, the second positioning block 222, and the third positioning block 223 are respectively reset under the action of elasticity, so that the first positioning block 221 and the second positioning block 222 are clamped at both ends of the workpiece 5 to achieve the positioning and fixing of the workpiece 5 in the first direction X, and the third positioning block 223 is clamped on the side and top surface of the workpiece 5 to achieve the positioning and fixing of the workpiece 5 in the second direction Y and the third direction Z. Therefore, the utility model can achieve movement in three directions with only one power source, unlock the positioning and fixing of the workpiece 5, facilitate the placement and removal of the workpiece 5, and evacuate the push assembly 23. The first positioning block 221, the second positioning block 222, and the third positioning block 223 are reset to the state of clamping the workpiece 5 under the action of elasticity, so as to achieve the positioning and clamping of the workpiece 5 in three directions, with fast action response and improved efficiency.

[0052] In some embodiments, the end surface of the third positioning block 223 at one end of the support portion 21 partially extends along the second direction Y to form a step 22331 with an opening facing downward. The formed step 22331 is used to clamp on the top and side surfaces of the workpiece 5 to facilitate clamping and positioning of the top and side surfaces of the workpiece 5.

When the first driving member 232 drives the push block 231 to push the transmission assembly 224, the push block 231 abuts against the first abutting part 22421, the second abutting part 22431 and the third abutting part 22441. The pushing block 231 pushes the first abutting portion 22421 and the second abutting portion 22431, so that the first abutting portion 22421 and the second abutting portion 22431 move away from each other, driving the first transmission portion 2242 and the second transmission portion 2243 to slide along the connecting beam 2241 and move away from each other, thereby causing the first positioning block 221 and the second positioning block 222 to move away from each other. When the pushing block 231 pushes the third abutting portion 22441, the third abutting portion 22441 moves along the third direction Z, driving the third transmission portion 2244 to move along the third direction Z, and the third transmission portion 2244 drives the first transmission portion 2242 and the second transmission portion 2243 to move along the third direction Z through the connecting beam 2241, thereby causing the first positioning block 221 and the second positioning block 222 to move away from the support portion 21 along the third direction Z. In some embodiments, the first transmission portion 2242 and the second transmission portion 2243 are columnar structures extending along the second direction Y, respectively. The sliding directions of the first transmission part 2242 and the second transmission part 2243 both extend along the first direction X. A slide rail 22411 can be arranged on the connecting beam 2241, and the first transmission part 2242 and the second transmission part 2243 are respectively slidably assembled on the slide rail 22411. The first transmission part 2242 and the second transmission part 2243 slide along the slide rail 22411 to move away from or approach each other.

The two connecting plates 22443 are respectively connected to the two ends of the connecting beam 2241. The third abutting part 22441 is arranged on the connecting rod 22442. The connecting rod 22442 extends along the first direction X. The pushing block 231 presses the third abutting part 22441 and the connecting rod 22442 to move along the third direction Z, so that the connecting plate 22443 drives the connecting beam 2241 to move.

[0054] See also Figure 8 In some embodiments, the transmission assembly 224 further includes a first guide column 2245 and a second guide column 2246, which are arranged at intervals at both ends of the connecting beam 2241 along the first direction X, and the first guide column 2245 and the second guide column 2246 extend out of the workbench 1 along the third direction Z, respectively.

The first guide column 2245 and the second guide column 2246 are arranged to penetrate the workbench 1, guide the movement of the transmission assembly 224 in the third direction Z, and facilitate the installation of the first elastic member 22451, so that the transmission assembly 224 automatically resets under the elastic force of the first elastic member 22451 after losing the abutment effect. The first elastic member 22451 is a compression spring.

[0055] See also Figure 8 In some embodiments, the transmission assembly 224 further includes a first stop block 2247 and a second stop block 2248, which are arranged on the connecting beam 2241 at intervals along the first direction X. A second elastic member 22471 is connected between the first transmission part 2242 and the first stop block 2247, and between the second transmission part 2243 and the second stop block 2248, respectively. The elastic expansion direction of the second elastic member 22471 is parallel to the first direction X. The second elastic member 22471 is a compression spring, which enables the first transmission part 2242 and the second transmission part 2243 to reset under the action of elastic force after losing the abutment effect. The first transmission part 2242 and the second transmission part 2243 are arranged between the first stop block 2247 and the second stop block 2248, so that the elastic forces on the first transmission part 2242 and the second transmission part 2243 are in opposite directions, so that the first transmission part 2242 and the second transmission part 2243 are close to each other under the action of elastic force.

[0056] See also Figure 8In some embodiments, the first abutting portion 22421 is rotatably mounted on the first transmission portion 2242; the second abutting portion 22431 is rotatably mounted on the second transmission portion 2243, and the third abutting portion 22441 is rotatably mounted on the third transmission portion 2244. When the pushing block 231 pushes the first abutting portion 22421, the second abutting portion 22431 and the third abutting portion 22441, the friction between the first abutting portion 22421, the second abutting portion 22431 and the third abutting portion 22441 and the pushing block 231 is rolling friction, which reduces friction. The first abutting portion 22421, the second abutting portion 22431 and the third abutting portion 22441 can be in the form of rollers or bearings.

[0057] See also Fig. 9 and Fig.10In some embodiments, the push assembly 23 includes a push block 231 and a first driving member 232. The first driving member 232 is in driving connection with the push block 231, and the first driving member 232 is used to drive the push block 231 to reciprocate along the second direction Y. The push block 231 is a block-shaped structure. The pushing block 231 has a fixed end 2311 and a pushing end 2312, the fixed end 2311 is transmission-connected to the first driving member 232, the pushing end 2312 is provided with a first abutting surface 23121, a second abutting surface 23122, a third abutting surface 23123 and a fourth abutting surface 23124, the first abutting surface 23121 and the second abutting surface 23122 are arranged opposite to each other along the first direction X, the first abutting surface 23121 and the second abutting surface 23122 are both inclined toward the direction of the center plane of the pushing end 2312, and the center plane is parallel to the center plane of the third direction Z; the third abutting surface 23123 is arranged on the side of the pushing end 2312 away from the fixed end 2311 along the second direction Y; the fourth abutting surface 23124 is arranged on the lower side of the pushing end 2312 and inclined upward. The first abutting surface 23121 and the second abutting surface 23122 are used to abut with the first abutting portion 22421 and the second abutting portion 22431 respectively. Since the first abutting surface 23121 and the second abutting surface 23122 are both inclined toward the center plane, in the second direction Y, the distance between the first abutting surface 23121 and the second abutting surface 23122 gradually increases toward the fixed end 2311. When the pushing block 231 pushes along the second direction Y, the pushing block 231 overcomes the elastic force of the second elastic member 22471 to squeeze the first abutting portion 22421 and the second abutting portion 22431 apart, and the first abutting portion 22421 keeps in contact with the first abutting surface 23121, and the second abutting portion 22431 keeps in contact with the second abutting surface 23122, so that the distance between the first abutting portion 22421 and the second abutting portion 22431 gradually increases with the movement of the pushing block 231, so that the first positioning block 221 and the second positioning block 222 move away from each other. When the pushing block 231 pushes along the second direction Y, the third abutting surface 23123 pushes the third positioning block 223, so that the third positioning block 223 moves along the second direction Y. The third abutment portion 22441 of the push transmission assembly 224 is pushed by the fourth abutment surface 23124. Since the fourth abutment surface 23124 is inclined, the height position of the fourth abutment surface 23124 in contact with the third abutment portion 22441 gradually decreases during the movement of the pushing block 231. The pushing block 231 overcomes the elastic force of the first elastic member 22451 and presses the third abutment portion 22441 to move along the third direction Z, so that the first positioning block 221 and the second positioning block 222 move along the third direction Z.

One positioning part 2233 is provided corresponding to one protrusion. A support column 22412 is provided on the connecting beam 2241, and the support column 22412 is extended along the third direction Z. The support column 22412 is used to support the middle position of the workpiece 5 to prevent the middle part of the workpiece 5 from sagging.

[0061] See also Figure 1 In some embodiments, the workbench 1 is further provided with a material taking position 13, and the material taking position 13 and the material discharging position 11 are arranged at intervals along the circumference of the workbench 1, and a positioning mechanism 2 is correspondingly provided at the material taking position 13. The PCM board positioning device also includes a base 3 and a second driving member 31, and the base 3 is arranged below the workbench 1; the second driving member 31 is installed on the base 3 and connected to the workbench 1 to drive the workbench 1 to rotate. The workbench 1 is driven to rotate by the second driving member 31, and the positions of the material discharging position 11 and the material taking position 13 rotate synchronously with the workbench 1. After a material discharging position 11 is discharged, the rotating workbench 1 rotates the workpiece 5 at the material discharging position 11 to the material taking position 13, so as to facilitate the removal of the workpiece 5. While taking out the workpiece 5, the workpiece 5 can continue to be placed in the material discharging position 11, thereby improving efficiency. Both the placing and taking out of the workpiece 5 can be operated by a manipulator. In some embodiments, the material discharging position 11 and the material taking position 13 are arranged in one-to-one correspondence, for example, one material discharging position 11 and one material taking position 13 are arranged respectively, or two material discharging positions 11 and two material taking positions 13 are arranged respectively, one material discharging position 11 corresponds to one material taking position 13, and another material discharging position 11 corresponds to another material taking position 13. In some embodiments, one material taking position 13 and one material discharging position 11 are arranged respectively, and the material taking position 13 is arranged opposite to the material discharging position 11, and the second driving member 31 drives the workbench 1 to rotate 180° each time. The second driving member 31 is a direct drive motor or a rotary cylinder, etc.

[0062] It should be noted that when the workbench 1 is provided with only one material discharge position 11, the material discharge position 11 is used for both material discharge and material collection.

[0063] See also Figure 1 In some embodiments, the PCM board positioning device further includes a height detection member 4 mounted on the base 3. The height detection member 4 is used to detect the height position of the material taking position 13, monitor the repetitive accuracy of each rotation of the workbench 1, and reduce the positioning error of the workpiece 5 caused by the rotation accuracy of the workbench 1. The height detection member 4 is a displacement sensor.

[0064] In some embodiments, the PCM board positioning device further includes a sensor and a controller. The sensor is installed on the workbench 1 and opposite to the support portion 21. The sensor and the push assembly are electrically connected to the controller, specifically, the first driving member 232 of the push assembly is electrically connected to the controller. The sensor is used to detect whether there is a workpiece 5 on the support portion 21 to avoid malfunction of the push mechanism. When there is no workpiece 5 on the support portion 21, the first driving member 232 drives the push block 231 to move, so that the first positioning block 221, the second positioning block 222 and the third positioning block 223 are all away from the support portion 21, so as to facilitate the placement of the workpiece 5. When there is a workpiece 5 on the support portion 21, the first driving member 232 drives the push block 231 to move in the opposite direction, so that the first positioning block 221, the second positioning block 222 and the third positioning block 223 are close to the support portion 21, and the workpiece 5 on the support portion 21 is positioned and clamped. The sensor is a photoelectric sensor.

[0065] Taking a discharging position 11 and a taking position 13 as an example, the working process of the utility model is as follows:

[0066] Discharging process: The first driving member 232 drives the push block 231 to move along the second direction Y and approach the transmission assembly 224. When the push block 231 abuts the transmission assembly 224, the first abutting portion 22421 and the second abutting portion 22431 are abutted by the first abutting surface 23121 and the second abutting surface 23122 to overcome the elastic force of the second elastic member 22471 and move away from each other, so that the first positioning block 221 and the second positioning block 222 move away from each other along the first direction X. The third abutting portion 22441 is abutted by the fourth abutting surface 23124 to overcome the elastic force of the first elastic member 22451 and move along the third direction Z, driving the first positioning block 221 and the second positioning block 222 to move along the third direction Z away from the support portion 21. The third positioning block 223 is abutted by the third abutting surface 23123 to overcome the elastic force of the third elastic member and move along the second direction Y, and the third positioning block 223 moves away from the support portion 21. The first positioning block 221, the second positioning block 222 and the third positioning block 223 are all away from the support part 21, avoiding the placement position of the workpiece 5 on the support part 21, and the workpiece 5 is placed on the support part 21 by the manipulator. The first driving member 232 drives the push block 231 to move in the opposite direction away from the transmission assembly 224, and the transmission assembly 224 and the third positioning block 223 lose the abutment effect of the push block 231. The transmission assembly 224, the first positioning block 221, the second positioning block 222 and the third positioning block 223 are automatically reset under the action of elastic force, so that the first positioning block 221 and the second positioning block 222 are respectively clamped at the two ends of the workpiece 5, and the positioning and clamping of the workpiece 5 in the first direction X is realized; the third positioning block 223 is clamped on the top surface and the side surface of the workpiece 5, and the positioning and clamping of the workpiece 5 in the second direction Y and the third direction Z is realized, so that the workpiece 5 is kept in the set posture, and the material discharge process of the workpiece 5 is completed.

[0067] Retrieving process: The worktable 1 is rotated by the second driving member 31 to rotate the workpiece 5 at the material discharging position 11 to the material retrieving position 13. The first driving member 232 corresponding to the material retrieving position 13 drives the pushing block 231 to approach the transmission assembly 224, and pushes the transmission assembly 224 and the third positioning block 223, so that the first positioning block 221, the second positioning block 222, and the third positioning block 223 are all away from the support part 21, avoiding the position of the workpiece on the support part 21, and the workpiece 5 is taken out by the manipulator with the set posture. In this way, the retrieving process of the workpiece 5 is completed.

[0068] While taking out the workpiece 5 from the material taking position 13, the material placing process can be repeated to place the workpiece 5 on the support portion 21 of the material placing position 11. The material placing and material taking process is performed in this way to realize the positioning of multiple workpieces 5.

[0069] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
