Description

Technical Field

[0001] This utility model relates to the field of hot press welding technology, and in particular to a hot press welding device and equipment having the hot press welding device. Background Technology

[0002] Thermostatic welding is a welding technology that combines heating and pressure. It is widely used in electronic manufacturing and microelectronic packaging. For example, when welding circuit boards, thermostatic welding can simultaneously complete the precision welding of multiple contacts, making it suitable for the processing of high-precision electronic equipment.

[0003] Chinese utility model patent (CN219436331U) discloses an automatic thermoforming welding device for cables. The device features a bonding sheet at the upper end of a first longitudinal sliding block and a pressure sensor at the upper end of the interior of the longitudinal sliding strip. In actual use, the heating block moves longitudinally and completes the thermoforming welding process through heating and pressing. After the first longitudinal sliding block slides longitudinally and the processing ends, the pressure sensor detects the pressing. This triggers the rotation of an output gear and the transmission gear groove, causing the transmission fixing plate and the lower-end suspended camera lens to extend outside the collection frame. The camera lens can directly capture images of the thermoforming welding position on the material placement plate and magnify them for user viewing. The camera structure can be stored in a storage box or extend outside the collection frame according to the user's shooting needs. The storage and extension can protect the camera lens, and the extended position allows the camera lens to be close to the processing position on the upper end of the material placement plate.

[0004] However, in actual production applications, this device takes pictures by moving the camera to the processing position. Since the camera is a high-precision component, if the camera is used as a moving part, it may still collide with other parts if the operator does not operate it properly, thus causing damage and affecting the production process.

[0042] Please see Figures 1-2 In this embodiment of the present invention, a hot press welding device includes a working platform 1 and a fixture 2 for positioning a circuit board. The fixture 2 is slidably mounted on the working platform 1. The fixture 2 can move back and forth on the working platform 1 only through a first sliding mechanism 6. The fixture 2 can move from the beginning to the end. The working platform 1 has two first support frames 11 on both sides of the beginning of the fixture 2. A connecting plate 12 is installed between the two first support frames 11. The beginning of the fixture 2 is below the connecting plate 12.

The connecting plate 12 is equipped with a lifting mechanism 5 to control the lifting and lowering of the hot press welding head 3. The connecting plate 12 is also equipped with a second sliding mechanism 7 to drive the hot press welding head 3 to slide back and forth along the direction of the connecting plate 12. At the end of the fixture 2, a... A detection module 4 for detecting solder contact points on a circuit board is provided. The detection module 4 includes a second support frame 41 and a camera 42. The second support frame 41 is arched or "door" shaped and is mounted on the work platform 1. The second support frame 41 and the work platform 1 form a frame structure. In this embodiment, the frame structure is "mouth" shaped. The movement trajectory of the fixture 2 is located within the frame structure. When the fixture 2 moves from the beginning to the end, it passes through the second support frame 41. The camera 42 is detachably mounted on the second support frame 41 and is located at the upper end of the frame structure. The camera output end of the camera 42 faces the work platform 1 and is used to take pictures of the circuit board placed on the fixture 2 when the fixture 2 passes through the second support frame 41 to detect solder contact points.

[0043] Specifically, two first support frames 11 are located on both sides of the fixture 2. Multiple sets of fixtures 2 can be provided between the two first support frames 11 on the work platform 1. In this embodiment, the work platform 1 has two sets of fixtures 2 located between the two first support frames 11. The connection method between the hot-press welding head 3 and the connecting plate 12 includes, but is not limited to, threaded connection, snap-fit ​​connection, and riveting. The connection method between the camera 42 and the second support frame 41 includes, but is not limited to, threaded connection, snap-fit ​​connection, and riveting. The connection method between the end of the connecting plate 12 and the first support frame 11 includes, but is not limited to, threaded connection, snap-fit ​​connection, and riveting.

[0044] The working principle of this embodiment is as follows: The first sliding mechanism 6 is used to move the fixture 2 to the camera 42 to detect the welding contact points. After the image is taken, the welded circuit board is taken out and the fixture 2 is reset to perform welding on the next batch of circuit boards. The second support frame 41 is used to install the camera above the fixture 2 and away from the welding operation area. The camera's shooting range partially overlaps with the movable position of the fixture 2. When the fixture 2 moves, it can complete the detection of welding contact points by passing through the camera's shooting range, which effectively prevents the camera from colliding with other components.

[0045] Further as Figures 3-5 As shown, in this embodiment of the present invention, the first sliding mechanism 6 includes a first lead screw 61 rotatably mounted on the working platform 1, a first motor 62 mounted on the working platform 1 for driving the first lead screw 61 to rotate, a first sliding seat 63, and at least two first guide members 64. The first sliding seat 63 has a first threaded through hole 631 for threaded connection with the first lead screw 61. The bottoms of the two first guide members 64 are respectively mounted on the working platform 1. The bottom of the first sliding seat 63 has two first limiting grooves 632. The tops of the two first guide members 64 are respectively locked in the two first limiting grooves 632 to restrict the rotation of the first sliding seat 63 about the first lead screw 61. A fixture 2 is mounted on the upper end of the first sliding seat 63.

[0046] Specifically, the first lead screw 61 is arranged on the work platform 1 in a back-to-forth direction. The specific implementation of the first lead screw 61 being rotatably mounted on the work platform 1 can adopt existing technical solutions known to those skilled in the art, and will not be elaborated upon here. The first guide member 64 can be a columnar structure, and the groove shape of the first limiting groove 632 corresponds to the cross-sectional shape of the first guide member 64. For example, the first limiting groove 632 can be "H" shaped, dovetail groove shaped, or conical, etc. The connection relationship between the first guide member 64 and the work platform 1 includes, but is not limited to, threaded connection, snap-fit ​​connection, and riveting.

[0047] The working principle of this embodiment is as follows: When the first motor 62 is energized, it drives the first lead screw 61 to rotate. The first sliding seat 63 located on the first lead screw 61 is threadedly connected to the first lead screw 61, converting the rotational motion of the first lead screw 61 into the linear reciprocating motion of the first sliding seat 63 in the back-and-forth direction. The fixture 2 moves synchronously with the first sliding seat 63.

[0048] Further as Figures 6-10 As shown, in this embodiment of the present invention, the lifting mechanism 5 includes a sliding plate 51, a second lead screw 52, ​​a second motor 53, and a second sliding seat 54.

The second motor 53 is mounted on the upper end of the sliding plate 51. The output end of the second motor 53 is connected to the second lead screw 52 to drive the second lead screw 52 to rotate. The second sliding seat 54 has a second threaded through hole 541 for threaded connection with the second lead screw 52. The two sides of the sliding plate 51 are respectively provided with locking parts 511 for locking the two sides of the second sliding seat 54. One end of the hot-press welding head 3 is mounted on the second sliding seat 54.

[0049] Specifically, the locking part 511 also serves to restrict the rotation of the second sliding seat 54 about the lead screw, similar to the function of the first guide member 64 and the first limiting groove 632 in the first sliding mechanism 6. In this embodiment, two flanges extend from both sides of the end face of the sliding plate 51 where the second sliding seat 54 is mounted. Through grooves are formed on the inner sides of the flanges. Slider blocks for locking within the through grooves are correspondingly formed on both sides of the second sliding seat 54. When the second sliding seat 54 is slidably mounted on the sliding plate 51, the sliders on both sides of the second sliding seat 54 are locked within the through grooves, thereby restricting the rotation of the first sliding seat 63 about the second lead screw 52. The connection relationship between the locking part 511 and the two sides of the second sliding seat can be referred to in the above embodiment. The second lead screw 52 is arranged longitudinally on the sliding plate 51. The connection methods between the sliding plate 51 and the connecting plate 12 include, but are not limited to, threaded connections, snap-fit ​​connections, and riveting. The connection methods between the hot-press welding head and the second sliding seat 54 include, but are not limited to, threaded connections, snap-fit ​​connections, and riveting.

The second sliding seat 54 located on the second lead screw 52 is threadedly engaged with the second lead screw 52, ​​converting the rotational motion of the second lead screw 52 into the linear reciprocating motion of the second sliding seat 54 in the longitudinal direction. The hot pressing welding head 3 moves synchronously with the second sliding seat 54.

[0051] Further as Figures 11-12As shown in this embodiment of the present invention, the connecting plate 12 is provided with a second sliding mechanism 7 for driving the hot-press welding head 3 to move back and forth. The second sliding mechanism 7 includes a third sliding seat 71, a third lead screw 72, a third motor 73 and at least two second guide members 74 disposed between the sliding plate 51 and the connecting plate 12. The third lead screw 72 is rotatably mounted on the connecting plate 12. The third motor 73 is mounted on one side of the connecting plate 12. The output end of the third motor 73 is connected to the third lead screw 72 to drive the third lead screw 72 to rotate. One end of the third sliding seat 71 is provided with a third threaded through hole 711 for threaded connection with the third lead screw 72. The back of the sliding plate 51 is mounted on the third sliding seat 71. The two second guide members 74 are respectively mounted on the connecting plate 12. Two second limiting grooves 75 are opened at the bottom of the third sliding seat 71. The two second guide members 74 are respectively locked in the two second limiting grooves 75 to limit the rotation of the third sliding seat 71 about the third lead screw 72.

[0052] Specifically, the connection between the sliding plate 51 and the third sliding seat 71 includes, but is not limited to, threaded connection, snap-fit ​​connection, and riveting.

The connection between the second guide member 74 and the connecting plate 12 includes, but is not limited to, threaded connection, snap-fit ​​connection, and riveting. The third lead screw 72 is installed on the connecting plate 12 in a left-right direction. Working principle of this embodiment: When the third motor 73 is energized, it drives the third lead screw 72 to rotate. The third sliding seat 71 located on the third lead screw 72 engages with the third lead screw 72 threadedly, converting the rotational motion of the third lead screw 72 into the linear reciprocating motion of the third sliding seat 71 in the lateral direction. The hot-press welding head 3 moves synchronously with the third sliding seat 71.

[0053] Further as Figure 2 As shown, in this embodiment of the present invention, the detection module 4 further includes a controller 44 for detecting images captured by the camera 42. The controller 44 is electrically connected to the camera 42. Specifically, the controller 44 can be a computer. The camera 42 transmits the captured images to the computer.

Both fixtures 2 are located between two first support frames 11, and two cameras 42 are correspondingly provided on the second support frame 41.

[0055] Further as Figures 1-2As shown, in this embodiment of the present invention, the camera 42 is provided with a light source 43, which is installed at the shooting output end of the camera 42 for supplementary lighting. Specifically, a light bulb can be used as the light source 43.

[0057] Specifically, sensor 82 can be a photoelectric sensor, and the photoelectric sensor model can be PE11 or FPM24.

[0059] In this embodiment of the utility model, a hot press welding device includes the above-mentioned hot press welding apparatus.

[0060] The working principle of this utility model is as follows: The worker places the circuit board to be welded on the fixture 2. The second motor 53 is energized, driving the second lead screw 52 to rotate. The second sliding seat 54 located on the second lead screw 52 engages with the threaded second lead screw 52, ​​converting the rotational motion of the second lead screw 52 into the longitudinal reciprocating linear motion of the second sliding seat 54. The hot-press welding head 3 moves synchronously with the second sliding seat 54 to weld the circuit board. After the contacts of the circuit board are welded, the first motor 62 is energized to drive the first lead screw 61 to rotate. The sliding seat 63 engages with the first lead screw 61, converting the rotational motion of the first lead screw 61 into a linear reciprocating motion in the back-and-forth direction of the first sliding seat 63. The first sliding seat 63 drives the fixture 2 to move synchronously. The second support frame 41 mounts the camera above the fixture 2 and away from the welding operation area.
