The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Please refer to fig. 1 to 11. Embodiments of the present application provide a hot press system including a support frame 70, a mounting frame 80, a first driver 91, a plurality of hot press assemblies 10, and a plurality of third drivers 92.

Wherein the mounting bracket 80 is slidably coupled to the support bracket 70. The moving end of the first driving member 91 is fixedly connected with the mounting frame 80, and is used for driving the mounting frame 80 to move in the vertical direction Z. A plurality of hot press assemblies 10 are mounted on a mounting frame 80. The thermocompression assembly 10 includes a mount 6, a thermocompression head 1, and a second driving member 4. The moving end 41 of the second driving member 4 is fixedly connected with the thermal head 1, and is used for driving the thermal head 1 to move along the first direction X to approach or separate from the product. The fixed end 42 of the second driving member 4 is fixedly mounted to the mounting seat 6. The first direction X is perpendicular to the vertical direction Z. The third driving piece 92 corresponds to the hot pressing assembly 10 one by one, the fixed end of the third driving piece 92 is fixedly connected with the mounting frame 80, and the moving end of the third driving piece 92 is fixedly connected with the mounting seat 6 and used for driving the mounting seat 6 to drive the hot pressing head 1 to move in the vertical direction Z.

In the hot pressing system provided in this embodiment, the first driving member 91, the mounting frame 80 and the supporting frame 70 are provided, so that the plurality of hot pressing assemblies 10 mounted on the mounting frame 80 can be lifted and lowered simultaneously; by providing a plurality of third driving members 92 in one-to-one correspondence with the hot press assemblies 10, the individual lifting of each hot press assembly 10 can be achieved. Therefore, the hot pressing assembly 10 can be lifted independently and synchronously, and can avoid the collision with the moving products or other parts well.

In the present embodiment, the thermo-compression assembly 10 further includes a force control mechanism 3, and the force control mechanism 3 includes a first slide rail 31, a second slide rail 32, a first slider 33, a second slider 34, a first connection block 35, a second connection block 36, a pressure sensor 37, and a first spring 38. The second sliding rails 32 are located above the first sliding rails 31 and all extend along the first direction X. The first direction X is parallel to the front-rear direction. The first slider 33 is slidably connected to the first slide rail 31, and the second slider 34 is slidably connected to the second slide rail 32. The lower surface of the first connection block 35 is fixed to the upper surface of the first slider 33, and the lower surface of the second connection block 36 is fixed to the upper surface of the second slider 34. The first connection block 35 has a first portion 351 located below the second slide rail 32 and a second portion 352 facing the rear end of the second connection block 36, and the pressure sensor 37 and the first spring 38 are located between the second portion 352 and the second connection block 36. The front end of the second connecting block 36 is fixedly connected with the thermal head 1. In the initial state, the rear end of the first connection block 35 and the front end of the second portion 352 have a first predetermined distance in the first direction X, and the first spring 38 is in a natural state. The first spring 38 is retractable in a first direction X. The initial state may refer to a state of the thermo-compression device before the moving end 41 of the second driving member 4 moves (when the length of the moving end extending out of the fixed end is the smallest).

The moving end 41 of the second driving member 4 is fixedly connected to the rear end of the second portion 352 for driving the first link 35 to move in the first direction X.

According to the hot pressing system provided by the embodiment, by arranging the force control mechanism 3, the force control mechanism 3 not only uses a spring to realize force control, but also is provided with a double-layer sliding rail structure, and the hot pressing head 1 is pushed to move along the first direction X to have a buffering effect.

Specifically, when the thermal pressing head 1 reaches the thermal pressing surface, the second driving member 4 drives the first connecting block 35 to move forward, the first spring 38 is compressed, and the second connecting block 36 is pushed to drive the thermal pressing head 1 to move forward, so that the first spring 38 is restored to the natural state, at this time, the first connecting block 35 and the second connecting block 36 move forward together, and the value measured by the pressure sensor 37 is 0; when the hot pressing head 1 is propped against the hot pressing surface, the second driving piece 4 continuously drives the first connecting block 35 to move forwards, the first spring 38 is compressed, the hot pressing head 1 cannot continuously move forwards, so that the pressure sensor 37 can sense the pressure of the hot pressing head 1 on the hot pressing surface, the pressure of the hot pressing head 1 on the hot pressing surface is not more than a preset value through the monitoring of the pressure sensor 37, and the hot pressing device further has a reliable force control function.

In the present embodiment, as shown in fig. 8, the second portion 352 includes two side walls 354 and one rear wall 355, and the two side walls 354 and the one rear wall 355 enclose a receiving space 356 for receiving the pressure sensor 37 and the first spring 38. The rear end of the first spring 38 is fixed to the rear wall 355, and the front end is fixed to the pressure sensor 37. The front end of the pressure sensor 37 is fixed at the rear end of the second connection block 36, so that before the thermal compression head 1 reaches the thermal compression surface, the first connection block 35 can push the second connection block 36 to drive the thermal compression head 1 to move forward through the first spring 38 and the pressure sensor 37, the first spring 38 is basically in a natural state (once compressed, the pressure is restored to the natural state immediately), and the pressure sensed by the pressure sensor 37 is basically 0.

As shown in fig. 7, the side of the second connection block 36 is provided with a first receiving groove 361, and the first portion 351 is provided with a moving lever 353 extending into the first receiving groove 361. The moving lever 353 and the first receiving groove 361 have a second predetermined distance in the vertical direction Z so as not to hinder the relative movement between the first and second connection blocks 35 and 36. The second predetermined distance is smaller than the first predetermined distance, which is smaller because the vertical length of the first receiving groove 361 itself is smaller, and the second predetermined distance is only required to be greater than 0. The front-rear length of the moving lever 353 is smaller than the front-rear length of the first receiving groove 361, thereby allowing the moving lever 353 to move in the first direction X within the first receiving groove 361.

In one possible embodiment, the front-rear length of the first accommodation groove 361 is specifically designed according to the allowable range of the predetermined value of the pressure of the hot pressing head 1 against the hot pressing surface. When the thermal head 1 reaches the front of the thermal pressing surface, the rear surface of the moving lever 353 is substantially in contact with the rear surface of the first receiving groove 361; when the thermal pressing head 1 abuts against the thermal pressing surface, the moving rod 353 moves forward in the first accommodating groove 361 until the front surface of the moving rod 353 abuts against the front surface of the first accommodating groove 361, and the pressure sensor 37 senses that the pressure of the thermal pressing head 1 against the thermal pressing surface is the maximum pressure. Therefore, the force control function can be better realized by limiting the movable rod 353 through the first accommodating groove 361 and combining the pressure sensor 37.

Preferably, the upper surface of the second portion 352 is flush with the upper surface of the second slider 34, ensuring that the first spring 38 and the pressure sensor 37 are uniformly stressed. The lower surface of the second sliding rail 32 is fixed on the upper surface of the first portion 351, so that other supporting structures are omitted, and the whole structure is simpler and more compact.

In this embodiment, the hot press assembly 10 further includes a fine adjustment mechanism 2. As shown in fig. 7, 8 and 10, the fine adjustment mechanism 2 includes a first fine adjustment block 21, a second fine adjustment block 22 and a third fine adjustment block 23 which are disposed horizontally from bottom to top, and a first fixing block 24 which is disposed vertically. The fixed ends 42 of the first fixed block 24 and the second driving member 4 remain relatively stationary. The first fixing block 24 may be fixedly coupled to the front end of the second connection block 36.

As shown in fig. 11, the first fine adjustment block 21 and the first fixed block 24 are slidably connected by a first dovetail groove 251 extending in the vertical direction Z, so that the first fine adjustment block 21 can move in the vertical direction Z with respect to the first fixed block 24. The second trimming block 22 and the first trimming block 21 are slidably coupled by a second dovetail groove 252 extending in the second direction Y such that the second trimming block 22 is movable in the second direction Y relative to the first trimming block 21. The third trimming block 23 is rotatably connected to the second trimming block 22, and the third trimming block 23 is rotatable in a horizontal plane relative to the second trimming block 22. The thermal head 1 is fixedly attached to the upper surface of the third trimming block 23. Specifically, the thermal head 1 is fixedly connected to the upper surface of the third fine adjustment block 23 by the second fixing block 51. Thus, the thermal head 1 can be moved in the second direction Y, moved in the vertical direction Z, and rotated in the horizontal plane by the fine adjustment mechanism 2.

It should be noted that the first direction X, the second direction Y, and the vertical direction Z are perpendicular to each other, and the first direction X is parallel to the front-rear direction. The second direction Y and the first direction X are two directions perpendicular to each other in the horizontal plane. Unless otherwise specified, the second direction Y, the first direction X, and the vertical direction Z are not limited to a single direction, and may include a forward direction and a reverse direction (i.e., opposite directions), for example, the first direction X may include a forward direction and a backward direction, and the vertical direction Z may include a vertical upward direction and a vertical downward direction. As shown in fig. 5, in the first direction X, the side on which the thermal head 1 is located is referred to as "front", and the side on which the second driver 4 is located is referred to as "rear".

In the present embodiment, the first direction X and the second direction Y are for a single thermocompression assembly 10, and the first direction X and the second direction Y of different thermocompression assemblies 10 may be different, where the first direction X is a moving direction in which the second driver 4 drives the thermocompression head 1, and the second direction Y is a direction perpendicular to the first direction X in a horizontal plane.

As shown in fig. 10, the top end of the first fixing block 24 is provided with a second receiving groove 241, and the third fine adjustment block 23 is provided with an adjustment lever 231 extending into the second receiving groove 241. The first fixing block 24 is provided with a first fine adjustment member 261 extending along the second direction Y, one end of the first fine adjustment member 261 protrudes out of the first fixing block 24, and the other end abuts against the adjusting lever 231. The first fine adjustment member 261 is fixed to the first fixed block 24 by a fourth fastener 274 extending in the vertical direction Z. The adjusting rod 231 is provided with a second spring 242 on a side facing away from the first fine adjustment member 261, and the second spring 242 is located in the second accommodating groove 241 and abuts between the adjusting rod 231 and the first fixing block 24. The third trimming block 23 and the second trimming block 22 are fixedly connected by a first fastener 271 extending in the vertical direction Z, and the first fastener 271 is detachable.

When it is necessary to rotate the third fine adjustment block 23 in the horizontal plane with respect to the second fine adjustment block 22, the first fastening member 271 and the fourth fastening member 274 are loosened to move the first fine adjustment member 261 in the second direction Y, so that the adjustment lever 231 is moved in a direction approaching or moving away from the second spring 242, the second spring 242 is compressed or extended, and the second fine adjustment block 22 is rotated centering on the position where the first fastening member 271 is located. After the adjustment is completed, the first fastener 271 and the fourth fastener 274 are fastened.

As shown in fig. 10, a second fastening member 272 extending in the second direction Y and a second trimming member 262 extending in the vertical direction Z are provided between the first fixing block 24 and the first trimming block 21. The second fastener 272 is removable. When it is desired to move the first trimming block 21 in the vertical direction Z relative to the first fixed block 24, the second fastener 272 is released and the second trimming member 262 is rotated to move the first trimming block 21 in the vertical direction Z. After the adjustment is completed, the second fastener 272 is tightened.

As shown in fig. 10, a third fastening member 273 extending in the vertical direction Z is provided between the second fine adjustment block 22 and the first fine adjustment block 21, and a third fine adjustment member 263 extending in the second direction Y is provided between the first fixing block 24 and the second fine adjustment block 22. The third fastener 273 is detachable. When it is desired to move the second trimming block 22 in the second direction Y relative to the first trimming block 21, the third fastener 273 is loosened and the third trimming member 263 is rotated to move the second trimming block 22 in the second direction Y. After the adjustment is completed, the third fastener 273 is fastened. The third fine adjustment block 23 is provided with a through hole extending in the vertical direction Z through which the third fastening member 273 passes.

As shown in fig. 6 and 7, the moving end 41 of the second driving member 4 is fixedly connected to the rear end of the second portion 352 through a third fixing block 52, and the third fixing block 52 is connected to a fourth fixing block 53 at one end of the second direction Y, and a photo-sensing piece 531 is fixedly arranged on the fourth fixing block 53. A photoelectric sensor 43 is fixedly arranged on the fixed end 42 of the second driving member 4. In the initial state, the photo sensor piece 531 senses the photo sensor 43.

In the present embodiment, as shown in fig. 4, the mount 6 includes a first mount block 61 and a second mount block 62. The first slide rail 31 is fixedly mounted to the upper surface of the first mounting block 61. The second mounting block 62 is located behind the first slide rail 31 for fixedly mounting the fixed end 42 of the second driving member 4.

Specifically, the moving end of the third driving member 92 is fixedly coupled to the lower surface of the first mounting block 61. The movable end of the third driving member 92 is fixedly connected with the front surface of the second mounting block 62, the front surface of the second mounting block 62 is fixedly provided with a third sliding block 621, and the mounting frame 80 is provided with a third sliding rail 81 which extends along the vertical direction Z and is matched with the third sliding block 621. So set up, the third driving piece 92 directly drives the first installation piece 61 to drive the second installation piece 62 to move through the sliding structure of the third sliding rail 81 and the third sliding block 621, but not directly drive the first installation piece 61 and the second installation piece 62, so that the labor-saving effect can be achieved. Furthermore, the mounting seat 6 is not integrally provided, but includes the first mounting block 61 and the second mounting block 62, so that the weight of the hot press assembly 10 can be reasonably distributed, and the overall structure is more reliable.
