Technical Field

[0001] The utility model relates to an assembly device, in particular to a linkage clamping and positioning device. Background Art

[0002] Mobile phone camera modules are assembled from multiple parts. To improve efficiency, automated assembly is often used. Automated assembly requires clamping and positioning of the parts. For example, during the assembly of the camera body and the flexible cable, the camera body needs to be clamped and positioned, and then the flexible cable connector needs to be plugged into the camera body. To facilitate the insertion of the camera body into the fixture, at least two movable clamps are required for clamping. These two clamps are located on two adjacent sides. The two clamps require two drive mechanisms, which are perpendicular to each other. These drive mechanisms primarily use pneumatic or electric cylinders. Because pneumatic and electric cylinders are large and perpendicular to each other, only one camera body can be placed on the fixture, reducing assembly efficiency and increasing the size of the fixture.

[0026] The present invention will now be further described with reference to the accompanying drawings.

[0027] like Figures 1 to 10 As shown, a linked clamping and positioning device includes a base 2, a positioning base 5, a direct pressure device 3, and a side pressure device 4. The base 2 has a mounting slot 21 at the top and a base plate 1 at the bottom, which facilitates installation on assembly equipment or an assembly line. The positioning base 5, the direct pressure device 3, and the side pressure device 4 are each provided in an array, three in number, in a one-to-one correspondence. The positioning base 5 is mounted on one side of the mounting slot 21. A first positioning block 51 and a second positioning block 52 are provided on the top of the positioning base 5. The first and second positioning blocks 51, 52 are arranged on adjacent sides of the positioning base 5 and are perpendicular to each other. The direct pressing device 3 is slidably installed on the other side of the mounting groove 21 through a first linear guide pair, and is arranged opposite to the first positioning block 51, and is used to press the workpiece onto the first positioning block 51; the side pressing device 4 is slidably installed on the mounting groove 21 through a second linear guide pair, and is arranged opposite to the second positioning block 52, and is used to press the workpiece onto the second positioning block 52; the linkage device is respectively connected to the direct pressing device 3 and the side pressing device 4, and is used to enable the direct pressing device 3 and the side pressing device 4 to clamp or release the workpiece synchronously.

[0028] The first linear guide pair and the second linear guide pair are perpendicular to each other, and the three side pressure devices 4 are all installed on the second linear guide pair. There are three first linear guide pairs.

[0029] The first positioning block 51 is L-shaped, and a first avoidance groove 53 is provided at the inner corner of the first positioning block 51. The first avoidance groove 53 can facilitate processing while avoiding interference with the workpiece, facilitating the placement and positioning of the workpiece and improving the positioning accuracy.

[0030] The workpiece is compressed by the side pressure spring 44 and the direct pressure spring 33 , which can effectively avoid damage to the workpiece and reduce the requirements for the driving device.

[0031] Two positioning holes are respectively provided at both ends of the base plate 1 to facilitate positioning of the linkage clamping and positioning device.

[0032] The linked clamping and positioning device is placed on the welding device, and the driving device is installed on the welding device and is arranged opposite to the linked clamping and positioning device.

[0033] Since only one driving device is required and the driving device is located on one side of the linked clamping and positioning device, the volume of the fixture is greatly reduced, making it easier to arrange multiple camera bodies and improving assembly efficiency.

[0034] like Figure 7 As shown, the direct pressure device 3 includes a direct pressure seat 31, a direct pressure block 32, a direct pressure spring 33 and a direct pressure plate 34. The direct pressure seat 31 is installed on the first slider, and the first slider is slidably installed on the first linear guide rail. The first linear guide rail is fixed to the bottom of the mounting groove 21. The top of the direct pressure seat 31 is equipped with a direct pressure block 32, and the direct pressure block 32 is arranged opposite to the first positioning block 51; one end of the direct pressure spring 33 is movably inserted into the direct pressure hole 311 of the direct pressure seat 31, and the other end is against the direct pressure plate 34. The direct pressure plate 34 is fixed to the first fixed groove 22 of the base 2 by screws. The first fixed groove 22 is communicated with the mounting groove 21. The direct pressure plate 34 facilitates the installation of the direct pressure seat 31 and the direct pressure spring 33, and is convenient for replacing direct pressure springs 33 with different pressures according to needs; the direct pressure spring 33 enables the direct pressure block 32 to press the workpiece tightly on the first positioning block 51.

[0035] like Figures 8 to 10 As shown, the side pressure device 4 includes a side pressure seat 41, a side pressure block 42, a side pressure spring 44 and a side pressure plate 45. The bottom of the side pressure seat 41 is provided with a bottom positioning groove 411, which is inserted into the second slider. The second slider is slidably mounted on the second linear guide rail, and the second linear guide rail is fixed to the bottom of the mounting groove 21; the top of the side pressure seat 41 is provided with a first positioning groove 412, and the bottom of the side pressure block 42 is provided with a first positioning boss 422. The side pressure block 42 is fixed to the side pressure seat 41 by screws, and the first positioning boss 422 is inserted into the first positioning groove 412. The first positioning boss 422 and the first positioning groove 412 prevent the side pressure block 42 from rotating and improve the positioning accuracy of the side pressure block 42. The side pressure block 42 is provided with a side pressure arm 421, which is also arranged opposite to the second positioning block 52. The side pressure arm 421 is used to press the workpiece against the second positioning block 52, and the side pressure arm 421 avoids interference with the straight pressure block 32. One end of the side pressure seat 41 is provided with a side pressure hole 413. One end of a side pressure spring 44 is movably inserted into the side pressure hole 413, while the other end abuts against a side pressure plate 45. The side pressure spring 44 is used to enable the side pressure block 42 to press the workpiece against the second positioning block 52. The side pressure plate 45 is fixed to the bottom of the mounting slot 21 and is located above the second linear guide rail. The side pressure plate 45 facilitates the positioning of the side pressure spring 44, facilitating overall installation.

[0036] The linkage device includes a linkage cam 61 and a linkage roller 62. The linkage cam 61 is arc-shaped. The linkage cam 61 is arranged on one side of the direct pressure seat 31 and is an integral structure with the direct pressure seat 31; the linkage roller 62 is rotatably installed on the side pressure seat 41 through the linkage shaft 63, and is movable against the linkage cam 61. The highest point of the linkage cam 61 is used to keep the side pressure block 42 away from the workpiece, and the lowest point of the linkage cam 61 is used to enable the side pressure block 42 to press the workpiece tightly onto the second positioning block 52.

[0037] A driving block 312 is provided at one end of the direct pressure seat 31, away from the direct pressure block 32. The driving block 312 is connected to a driving device to achieve the movement of the direct pressure block 32. The driving device can be a cylinder, etc. Since the driving block 312 drives the direct pressure block 32 to release the workpiece, the driving device has relatively low requirements and only needs to overcome the force of the direct pressure spring 33 and the side pressure spring 44. There is no need to precisely control the position of the direct pressure block 32. Therefore, three direct pressure blocks 32 can be driven simultaneously, greatly simplifying the structure.

[0038] In order to improve safety and reliability, a sealing plate 7 is also included. The sealing plate 7 is installed on the top of the base 2 and is located above the mounting groove 21. The sealing plate 7 is provided with a plurality of driving grooves 71, positioning grooves 72, side pressure grooves 74 and direct pressure grooves 73. The driving block 312 is movably inserted into the driving groove 71. The side pressure grooves 74 and the direct pressure grooves 73 are respectively located on both sides of the positioning groove 72 and are both connected to the positioning groove 72. The positioning base 5 is located in the positioning groove 72. The side pressure block 42 and the side pressure seat 41 are movably inserted into the side pressure groove 74. The direct pressure seat 31 and the direct pressure block 32 are movably inserted into the direct pressure groove 73. The sealing plate 7 prevents the workpiece from falling into the mounting groove 21 and prevents external debris from entering the mounting groove 21, preventing debris from getting stuck in the direct pressure seat 31 and the side pressure seat 41.

[0039] During operation, the driving block 312 moves in the direction away from the positioning base 5 under the action of the driving device, and the linkage cam 61 moves in the direction away from the positioning base 5. The linkage cam 61 pushes the linkage roller 62 to move from the lowest point of the linkage cam 61 to the highest point of the linkage cam 61, and the linkage roller 62 drives the side pressure seat 41 to move in the direction away from the positioning base 5, thereby making the straight pressure block 32 and the side pressure block 42 away from the workpiece, and then the workpiece is placed on the positioning base 5, and the two adjacent side surfaces of the workpiece respectively abut against the first positioning base 5. Block 51 and the second positioning block 52, then the driving device moves toward the positioning base 5, the driving block 312 moves toward the positioning base 5 under the action of the direct pressure spring 33, and the side pressure seat 41 moves toward the positioning base 5 under the action of the side pressure spring 44, and the direct pressure block 32 presses the workpiece onto the first positioning block 51. At this time, since the linkage roller 62 moves from the highest point to the lowest point along the linkage cam 61, the side pressure seat 41 can move toward the positioning base 5, and then press the workpiece onto the second positioning block 52 through the side pressure arm 421.

[0040] The driving device can be any one of a pneumatic cylinder, an electric cylinder or a linear module, and only one driving device is needed. It can also be connected to the driving device through a cross bar, and the cross bar is respectively arranged opposite to the three driving blocks 312. The three driving blocks 312 are driven simultaneously by one driving device, which greatly reduces the number of driving devices and reduces costs.
