[0047] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0048] like Figures 1 to 7 As shown, an embodiment of the present invention provides a pressing mechanism, including a support platform 1 and at least one first pressing component 2. The support platform 1 is used to place a material plate, and at least one first pressing component 2 is slidably connected to the support platform 1 along a first direction a, so that the position of the first pressing component 2 on the support platform 1 is adjustable. The first pressing component 2 is used to press the material plate onto the support platform 1.

[0049] Since the first clamping component 2 is slidably connected to the bearing platform 1 along the first direction a, when the size of the material plate changes, the first clamping component 2 can slide on the bearing platform 1 to adjust the position of the first clamping component 2, so that the first clamping component 2 can be aligned with the edge of the material plate or the part that needs to be clamped, thereby realizing the clamping of material plates of different sizes. It can adapt to the changes of material plates of different sizes within a certain range, reducing the need to replace or adjust the entire clamping device due to different material plate sizes.

[0050] In the actual PCB manufacturing process, the support platform 1 takes the form of an adsorption platform. The surface of the adsorption platform is provided with negative pressure holes, which are connected to a negative pressure device, thereby enabling the adsorption platform to generate an adsorption force on the board and fix the board onto the support platform 1.

[0051] However, when facing material plates of different sizes, especially different thicknesses, the adsorption effect of the bearing platform 1 will be affected when the material plate is thick, and the material plate cannot be closely and flatly attached to the surface of the bearing platform 1. This uneven state will seriously interfere with the subsequent processing procedure of the material plate, resulting in a decrease in processing precision.

[0052] In this embodiment, at least one first pressing assembly 2 is provided, and when the bearing platform 1 adsorbs the material plate, the first pressing assembly 2 is pressed on the material plate to apply a continuous and stable pressure to the material plate. Under this additional pressure, the material plate can overcome the adsorption obstacles caused by its own thickness and other factors, and be closely and flatly attached to the surface of the bearing platform 1, ensuring that the subsequent PCB processing process can be carried out smoothly and accurately.

[0053] In an embodiment, the number of first pressing assemblies 2 can be one or more, which needs to be determined according to the size of the material plate. "More" means more than or equal to two, and the meaning of "more" is the same in each embodiment. When the number of first pressing assemblies 2 is more than one, the plurality of first pressing assemblies 2 are arranged at intervals along the first direction a, and at least one first pressing assembly 2 is slidingly connected to the bearing platform 1 along the first direction a. By adjusting the position of at least one first pressing assembly 2 on the bearing platform 1, the pressing of material plates of different sizes can be adapted.

[0054] In an embodiment, as shown in Figure 1 , two first pressing assemblies 2 are provided, and the two first pressing assemblies 2 are used to press the opposite sides of the material plate in the first direction a. The two first pressing assemblies 2 are arranged at intervals in the first direction a, one of the first pressing assemblies 2 is fixedly arranged relative to the bearing platform 1, and the other first pressing assembly 2 is slidingly connected to the bearing platform 1. Alternatively, both of the first pressing assemblies 2 are slidingly connected to the bearing platform 1. Both of the above-mentioned two ways can realize the adjustment of the pressing range between the two first pressing assemblies 2, so as to adapt to the pressing of material plates of different sizes.

[0055] In an embodiment, as shown in Figure 2 , Figure 4 , the first pressing assembly 2 includes a first driving member 21, a transmission member, and at least one first pressing member 22, the first pressing member 22 is connected to the transmission member, and the transmission member is connected to the output end of the first driving member 21; the transmission member plays a role of transmitting power of the first driving member 21 to the first pressing member 22. The first driving member 21 can drive the transmission member to move, and then drive the first pressing member 22 to loosen or press the material plate. By applying appropriate pressure to the material plate through the first pressing member 22, the material plate is firmly fixed on the bearing platform 1, preventing the material plate from shifting, shaking or vibrating during processing, and ensuring the accuracy and stability of the operation.

[0056] The number of the first pressing members 22 can be set according to actual needs (at least one), and the size of the pressing force of the first pressing members 22 can be changed by adjusting the output of the first driving member 21 and the parameters of the transmission member, so that the first pressing assembly 2 can adapt to the pressing of material plates of different types, sizes and weights.

[0057] In an embodiment, as shown in Figure 2 , Figure 3 The first pressing member 22 includes a connecting member 221 and a pressing body 222. The connecting member 221 is installed on the transmission member, and the pressing body 222 is installed on the connecting member 221. The pressing body 222 has a pressing surface that can be attached to the surface of the material plate.

[0058] When the first driving member 21 provides power, the pressing body 222 is pressed against the material plate through the transmission member and the connecting member 221, and the pressing surface is in close contact with the surface of the material plate under the action of the pressing force. The pressing surface is closely attached to the surface of the material plate, greatly increasing the contact area between the two, thereby improving the effect of the pressing force.

[0059] The connecting member 221 is provided with a plurality of screw holes, and screws are screwed into the screw holes to fix the connecting member 221 on the transmission member. When it is necessary to adjust the position of the first pressing member 22 on the transmission member, the position of the connecting member 221 can be flexibly adjusted by loosening the screws in the screw holes to adapt to different working conditions. After adjustment, the screws are locked.

[0060] In an embodiment, as shown in Figure 3 The pressing body 222 includes a pressing plate 2221 and a plurality of pressing blocks 2222. The pressing plate 2221 is connected to the connecting member 221, and the plurality of pressing blocks 2222 are installed on the pressing plate 2221. The plurality of pressing blocks 2222 are connected to the connecting member 221 through the pressing plate 2221, and the side surfaces of the plurality of pressing blocks 2222 away from the pressing plate 2221 collectively form a pressing surface. The plurality of pressing blocks 2222 collectively act to uniformly apply a pressing force to the surface of the material plate. Since each pressing block 2222 is independently installed on the pressing plate 2221, when facing an uneven material plate surface, each pressing block 2222 can be adjusted according to its actual contact condition to better attach the pressing surface to the surface of the material plate.

[0061] In an embodiment, as shown in Figure 3 The pressing plate 2221 is provided with a plurality of sliding grooves 22215, and each pressing block 2222 is arranged in a sliding groove 22215 near the pressing plate 2221. Each pressing block 2222 can move in the corresponding sliding groove 22215 in the first direction a. By moving the pressing block 2222 in the sliding groove 22215, the position of the pressing block 2222 on the pressing plate 2221 can be adjusted, so that the pressing block 2222 can adapt to material plates of different shapes and sizes.

[0062] The sliding groove 22215 is a dovetail groove, and the shape of the side of the pressing block 2222 close to the pressing plate 2221 is adapted to the dovetail groove, which can effectively prevent the pressing block 2222 from falling out of the sliding groove 22215 during movement.

[0063] In an embodiment, the pressing plate 2221 is provided with a connecting hole 22216, and the pressing block 2222 is provided with a strip-shaped hole 22221 extending along the first direction a. A screw or a bolt is sequentially threaded through the connecting hole 22216 and the strip-shaped hole 22221, so as to fix the pressing block 2222 on the pressing plate 2221. When the position of the pressing block 2222 needs to be adjusted, the screw or the bolt is loosened, and then the pressing block 2222 can slide in the sliding groove 22215. After adjustment, the screw or the bolt is tightened again.

[0064] The strip-shaped hole 22221 provides sufficient adjustable space for the movement of the pressing block 2222 in the first direction a, so that there is a position available for connection in the entire movement range of the pressing block 2222, ensuring the flexibility and continuity of the connection.

[0065] In an embodiment, as shown in Figure 3 The pressing plate 2221 includes a first plate member 22211 and a plurality of second plate members 22212, and the plurality of second plate members 22212 are arranged at intervals on the first plate member 22211. Each of the second plate members 22212 is provided with a sliding groove 22215, so that the plurality of pressing blocks 2222 are connected to the plurality of second plate members 22212 one by one.

[0066] In an embodiment, the first pressing member 22 further includes an adjusting member 223, and the connecting member 221 is provided with a first hole 2213. The adjusting member 223 can pass through the first hole 2213 and abut against the pressing main body 222. The pressing main body 222 has a locked state and an unlocked state. When the pressing main body 222 is in the locked state, the pressing main body 222 is fixedly arranged relative to the connecting member 221. When the pressing main body 222 is in the unlocked state, the adjusting member 223 can drive the pressing main body 222 to rotate, so that the pressing surface can be attached to the surface of the material plate.

[0067] After the adjusting member 223 passes through the first hole 2213 on the connecting member 221, one end thereof abuts against the pressing main body 222. When the pressing main body 222 is in the locked state, the relative position between the pressing main body 222 and the connecting member 221 is fixed. When the position of the pressing main body 222 needs to be adjusted, the pressing main body 222 enters the unlocked state, and at this time the adjusting member 223 begins to play a role. By applying an external force to the adjusting member 223, the adjusting member 223 and the pressing main body 222 abut against each other, so as to drive the pressing main body 222 to rotate around a certain specific shaft or fulcrum, thereby achieving the purpose of adjusting the pressing surface.

[0068] When the thickness of the material plate is inconsistent at different positions, the adjusting piece 223 drives the compression main body 222 to rotate, so that the compression surface accurately fits the surface of the material plate, and ensures that each part of the material plate can be subjected to uniform and appropriate pressure during compression.

[0069] In an embodiment, as shown in Figure 3 The first compression piece 22 further includes a first locking screw 224. When the compression main body 222 is in a locked state, the first locking screw 224 connects the compression main body 222 and the connecting piece 221, so that the relative position of the compression main body 222 and the connecting piece 221 is fixed. The connecting piece 221 is provided with a fourth hole 2214, and the compression main body 222 is provided with a fifth hole 22213. The first locking screw 224 is threadedly connected in the fourth hole 2214 after passing through the fifth hole 22213.

[0070] The number of first locking screws 224 is not limited to one or more, and is determined according to the connection of the compression main body 222 and the connecting piece 221.

[0071] In an embodiment, as shown in Figure 3 The first compression piece 22 further includes a pre-positioning piece 225. The pre-positioning piece 225 is connected between the connecting piece 221 and the compression main body 222, and the pre-positioning piece 225 can pre-position the compression main body 222 on the connecting piece 221. The connecting piece 221 is provided with a second hole, and the compression main body 222 is provided with a third hole at a corresponding position. The pre-positioning piece 225 passes through the third hole and the second hole in sequence. The pre-positioning piece 225 and the third hole are connected in a clearance fit manner. This fit allows the pre-positioning piece 225 to have a certain degree of movement space in the second hole. Under the action of the adjusting piece 223, the compression main body 222 can rotate, thereby adjusting the compression surface.

[0072] Preferably, the pre-positioning piece 225 and the second hole are also connected in a clearance fit manner.

[0073] In an embodiment, the adjusting piece 223 is threadedly connected with the connecting piece 221. When the compression main body 222 is in an unlocked state, the adjusting piece 223 can drive the compression main body 222 to rotate around the pre-positioning piece 225 by rotating the adjusting piece 223.

[0074] The pre-positioning piece 225 serves as the fulcrum of the rotation of the compression main body 222, and one end of the adjusting piece 223 abuts against the compression main body 222. When the operator rotates the adjusting piece 223, the adjusting piece 223 moves in the first hole 2213 due to threaded transmission, and one end of the adjusting piece 223 exerts a force on the compression main body 222, so that the compression main body 222 rotates around the pre-positioning piece 225.

[0075] Further, the threaded connection has good transmission accuracy. When the rotating adjusting member 223 is rotated, each rotation can be converted into a relatively accurate displacement change. According to the actual thickness of the material plate, the rotation angle of the pressing main body 222 can be adjusted by controlling the rotation of the adjusting member 223.

[0076] In an embodiment, as shown in Figure 3 , the adjusting member 223 is provided with multiple adjusting members and is arranged at intervals along the second direction b, thereby providing more adjustment points. When the pressing main body 222 is rotated to fit the material plate, the operator can finely operate the adjusting members 223 at different positions. The first direction a and the second direction b intersect.

[0077] Further, when the first pressing assembly 2 is loosened and the pressing main body 222 is in the unlocked state, when the multiple adjusting members 223 are simultaneously rotated, the multiple adjusting members 223 jointly exert a force on the pressing main body 222, so that the pressing main body 222 can move away from the connecting member 221 within the movable range.

[0078] Taking two adjusting members 223 as an example, one adjusting member 223 is arranged on one side of the connecting member 221 along the second direction b, and the other adjusting member 223 is arranged on the other side of the connecting member 221 along the second direction b. By adjusting the two adjusting members 223, one end of the pressing main body 222 can be raised and the other end can be lowered, or one end of the pressing main body 222 can be lowered and the other end can be raised, so that the pressing surface can better fit the surface of the material plate.

[0079] In an embodiment, as shown in Figure 2 , Figure 4 , the transmission member includes a rotating shaft 23 and a linkage assembly 24. The first pressing member 22 is sleeved outside the rotating shaft 23. The linkage assembly 24 is connected between the output end of the first driving member 21 and the rotating shaft 23. The first driving member 21 can drive the rotating shaft 23 to rotate through the linkage assembly 24, so as to loosen or press the material plate. When the rotating shaft 23 rotates, the first pressing member 22 changes position with the rotation of the rotating shaft 23. When the first pressing member 22 moves away from the bearing platform 1, the material plate is loosened. When the first pressing member 22 moves close to the bearing platform 1, the material plate is pressed.

[0080] In an embodiment, as shown in Figure 2 , Figure 4As shown, the connecting rod assembly 24 comprises a first connecting rod 241 and a second connecting rod 242, one end of the first connecting rod 241 and one end of the second connecting rod 242 are rotatably connected, the other end of the first connecting rod 241 is connected to the output end of the first driving member 21, and the other end of the second connecting rod 242 is connected to the rotating shaft 23. Further, the other end of the second connecting rod 242 is fixedly connected to the rotating shaft 23. The first driving member 21 can drive the first connecting rod 241 and the second connecting rod 242 to rotate relatively, so as to drive the rotating shaft 23 to rotate, so that the first pressing member 22 loosens or presses the material plate.

[0081] With the driving of the first driving member 21, one end of the first connecting rod 241 rotates around the first axis, which can drive one end of the second connecting rod 242 to rotate around the first axis, and at the same time can drive the other end of the second connecting rod 242 to rotate around the central axis of the rotating shaft 23 together with the rotating shaft 23, so that the first pressing member 22 can press on the material plate or loosen the material plate.

[0083] In an embodiment, the output end of the first driving member 21 is connected with an adapter 26, the adapter 26 is rotatably connected with one end of the first connecting rod 241 close to the first driving member 21, and the first driving member 21 can drive the adapter 26 to move along the vertical direction, so as to drive one end of the first connecting rod 241 close to the first driving member 21 to rotate around the second axis, and at the same time drive one end of the first connecting rod 241 away from the first driving member 21 to rotate around the first axis, and the first axis is parallel to the second axis.

[0084] Among them, the first driving member 21 can be a pneumatic cylinder, and the linear motion of the output end of the first driving member 21 is converted into the rotary motion of the rotating shaft 23 through the adapter 26 and the connecting rod assembly 24, so that the first pressing member 22 can rotate.

Based on the first clamping member 22, the second clamping member 52 further applies pressure to the material plate, making the material plate firmly fixed on the support platform 1, preventing displacement, shaking, or vibration of the material plate during processing, and ensuring the accuracy and stability of the operation.

[0106] In an embodiment, the second driving member 51 is a rotary lifting cylinder, which can drive the second pressing member 52 to lift or lower to press or release the board. When the second pressing member 52 releases the board, the rotary lifting cylinder can drive the second pressing member 52 to rotate to avoid the board when the board is moved in or out of the carrying platform 1. The rotary lifting cylinder can realize the rotation and lifting movement of the second pressing member 52 simultaneously. When the board is moved in or out of the carrying platform 1, the second pressing member 52 is quickly avoided by the rotary action, so as to avoid the interference between the second pressing member 52 and the board. After the board is placed on the carrying platform 1, the rotary lifting cylinder drives the second pressing member 52 to rotate back and lower, so as to press the board.

[0107] In other alternative embodiments, the second driving member 51 can also be combined with a lifting cylinder and a rotary cylinder to realize the lifting and rotation of the second pressing member.
