[0002] In the automated assembly process, the placement of the product on the production line is extremely important to the assembly result. If the product is placed in the wrong position, it will lead to assembly failure or even collision. In order to ensure the accuracy of the product placement, a corresponding positioning structure is usually set on the conveying device to carry out corresponding clamping and installation of the product. However, this method still has the risk of clamping errors, especially for products that need to be flipped for installation. The coordination requirements of the flipping device and the conveying device are extremely high. Any problem with either one will cause the product to fail to be installed after being flipped, resulting in uneven placement or the product being placed at a height higher than the set height. The existing technology lacks measures to detect abnormal product heights, resulting in products with abnormal heights flowing into the assembly station, affecting production. Utility Model Content

[0033] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0034] The height detection device and assembly equipment of the present invention are described below with reference to the accompanying drawings.

[0035] like Figure 1 As shown, the utility model provides a height detection device, wherein the height detection device comprises:

[0036] The mounting base 1 is arranged on the frame and includes a mounting horizontal plate 11 suspended above the conveying device 100;

[0037] The detection component 2 includes a baffle 21 and a detection control module. The upper end of the baffle 21 is hinged to the mounting cross plate 11, and the lower end of the baffle 21 is used to set the distance with the conveying device 100 to allow products with normal height to pass through. The detection control module is used to detect the position of the baffle 21 and issue an alarm when the position of the baffle 21 changes.

[0038] When using the above-mentioned height detection device, since it includes a mounting base 1 and a detection component 2, the mounting base 1 is arranged on a frame, and the mounting cross plate 11 on the mounting base 1 is suspended above the conveying device 100. In the detection component 2, the upper end of the baffle 21 is hinged to the mounting cross plate 11, and the lower end is spaced apart from the conveying device 100, and the size of the spacing is set to allow normally placed products to pass through. During the production process, the products pass through the baffle 21 in sequence under the drive of the conveying device 100. If the products are placed normally, they will not collide with the baffle 21 when passing through. If the products are placed incorrectly, such as tilted or placed at a height higher than the set height, the products will contact the baffle 21 when passing through. As the products continue to move, the baffle 21 will also swing around the hinge point with the mounting cross plate 11. At this time, the detection control module in the detection component 2 detects that the position of the baffle 21 has changed and issues an alarm, reminding the staff to correct the incorrectly placed products in time, so that the products can be assembled normally at the assembly station, thereby ensuring the normal operation of the production line.

[0039] Specifically, the upper end of the baffle plate 21 is hinged to the installation transverse plate 11 through a hinge 22. Of course, the installation transverse plate 11 can also be replaced with a straight rod, and a connecting hole extending along the length direction of the straight rod can be opened on the baffle plate 21.

[0040] It should be noted that the distance between the lower end of the baffle 21 and the conveying device 100 can be equal to the standard height of the product under normal placement. Taking into account that the product itself has a certain manufacturing tolerance, the distance between the lower end of the baffle 21 and the conveying device 100 can also be slightly larger than the standard height.

[0041] like Figure 2 and Figure 3As shown, in an embodiment of the utility model, the mounting base 1 includes a mounting vertical plate 12 standing on the frame and a mounting horizontal plate 11 arranged on the mounting vertical plate 12, and the mounting vertical plate 12 is provided with a limiting hole at a position corresponding to the baffle 21. The height detection device also includes a limiting component 3 with an elastic compression function and arranged in the limiting hole, and one end of the limiting component 3 extends out of the limiting hole for elastic compression abutment with the baffle 21. In the initial state, the baffle 21 is perpendicular to the mounting cross plate 11, and the limit assembly 3 extends from the limit hole and abuts against the rear panel surface of the baffle 21 to prevent the baffle 21 from swinging due to equipment vibration or other factors, thereby eliminating detection interference. When the product contacts the baffle 21, the baffle 21 swings backward, and during the swinging process, the limit assembly 3 is compressed by the pressure from the baffle 21, so that the baffle 21 can swing through. When the baffle 21 swings from the front position of the limit assembly 3 to the rear position, the limit assembly 3 rebounds and resets. At this time, the limit assembly 3 abuts against the front panel surface of the baffle 21 to stop it, so that the baffle 21 cannot be reset, thereby ensuring that the detection control module can accurately determine the position of the baffle 21.

[0042] Specifically, the side of the limit assembly 3 that contacts the rear plate surface of the baffle 21 can be set as an arc surface or an inclined surface, so that the lateral thrust of the baffle 21 on the limit assembly 3 during the backward swinging process is decomposed into a component force along the axial direction of the limit hole, so that the limit assembly 3 is gradually compressed to prevent the limit assembly 3 from getting stuck. Figure 3 An L-shaped fixing block 14 is also connected to the side of the mounting vertical plate 12 away from the mounting horizontal plate 11. The fixing block 14 is connected to the frame to increase the contact surface between the mounting seat 1 and the frame, thereby improving the stability of the height detection device.

[0043] It should be noted that for Figure 5 The turntable conveyor 100 shown is limited by the installation position, and the mounting seat 1 is provided with a mounting vertical plate 12 on the side of the conveyor 100. For the linear conveyor 100, the mounting vertical plate 12 can be provided with one or two at intervals. If a frame is also provided above the conveyor 100, the mounting horizontal plate 11 can also be mounted in a hanging manner.

[0044] like Figure 4 As shown, in the embodiment of the utility model, the limiting assembly 3 includes an elastic member 31 and a ball 32 arranged in the limiting hole, and the elastic member 31 is used to elastically drive the ball 32 to partially extend out of the limiting hole and abut against the baffle 21. Specifically, the elastic member 31 is preferably a compression spring, which has a simple structure and low cost. Of course, the elastic member 31 can also be set as an air spring, elastic rubber, etc.

[0045] like Figure 4As shown, in the embodiment of the utility model, the limiting assembly 3 also includes a column housing 33 for accommodating the elastic member 31 and the ball 32. The column housing 33 is placed in the limiting hole and has an opening formed at one end facing the baffle 21. The diameter of the opening is smaller than the diameter of the ball 32. The elastic member 31 is used to drive the ball 32 to extend from the opening. The limiting assembly 3 adopts an integrated setting, which is convenient for disassembly, assembly and replacement.

[0046] In the embodiment of the utility model, an external thread section is provided on the column shell 33, and the limiting hole is formed with an internal thread threadedly connected to the external thread section. By screwing the column shell 33, the extension amount of the column shell 33 can be freely changed, so that the hemispherical portion 322 of the ball 32 is just in contact with the baffle 21, thereby reducing the installation accuracy requirements of the baffle 21 and the mounting cross plate 11.

[0047] Specifically, the limit hole is a through hole, and a hexagonal hole is formed inwardly at the end of the column shell 33 away from the baffle 21. The operator can install and adjust the limit assembly 3 from the outside (i.e., the side of the height detection device away from the transfer device), and the outside activity space is large, which is convenient for operation.

[0048] In the embodiment of the utility model, the ball 32 includes a cylindrical portion 321 and a hemispherical portion 322 protruding from one end of the cylindrical portion 321. The elastic member 31 abuts against one end of the cylindrical portion 321 away from the hemispherical portion 322, and can drive the hemispherical portion 322 to extend from the opening. The diameter of the opening is larger than the diameter of the hemispherical portion 322 and smaller than the diameter of the cylindrical portion 321. One end of the cylindrical portion 321 facing the elastic member 31 is a flat surface, which is convenient for abutting against the elastic member 31 to receive force.

[0049] In the embodiment of the utility model, the installation horizontal plate 11 is arranged on the installation vertical plate 12 in an adjustable height, so that the height of the installation horizontal plate 11 can be adjusted according to different types of products, thereby improving the versatility of the device.

[0050] Specifically, a waist-shaped hole 121 extending in the height direction is formed on the mounting vertical plate 12, and the mounting seat 1 also includes a connecting bolt, which is height-adjustably inserted into the waist-shaped hole 121 and connected to the mounting horizontal plate 11, so that the position of the mounting horizontal plate 11 can be quickly adjusted according to the set height. Further, there are two waist-shaped holes 121, and the two waist-shaped holes 121 are arranged in parallel to ensure that the mounting horizontal plate 11 is parallel to the transmission surface of the conveying device 100, thereby ensuring the accuracy of positioning.

[0051] In addition to the above scheme, a screw lifting assembly can be set on the mounting vertical plate 12, and the mounting horizontal plate 11 is connected to the screw in the screw lifting assembly. By screwing the nut in the screw lifting assembly, the height of the mounting horizontal plate 11 can be accurately adjusted. Furthermore, a scale mark can be set on the screw. Before the product enters the conveying device, the operator can directly adjust the height according to the scale mark, thereby improving work efficiency.

[0052] In the embodiment of the utility model, the detection control module includes a proximity switch 23 and an alarm. The detection probe of the proximity switch 23 is arranged toward the baffle 21. The alarm is connected to the proximity switch 23 for communication and is used to sound an alarm when the position of the baffle 21 changes. The proximity switch 23 has high precision and does not need to be in direct contact with the baffle 21.

[0053] Specifically, a sensor mounting block 13 is also provided on the mounting vertical plate 12 to install and protect the proximity switch. Considering that the baffle 21 swings along the transmission direction, the sensor mounting block 13 is arranged on the front side of the baffle 21 to avoid interference. The detection probe of the proximity switch 23 is arranged toward the front panel surface of the baffle 21, and the alarm is used to sound an alarm when the baffle 21 is away from the sensor mounting block 13.

[0054] Of course, the present invention is not limited to this. The proximity switch 23 can also be replaced by an angle sensor or a contact sensor. If an angle sensor is used, it can be set on the baffle 21. If the baffle 21 is deflected, the alarm will sound an alarm. If a contact sensor is used, the contact sensor can be magnetically connected to the baffle 21 by setting a magnetic material. After the product hits the baffle 21, the magnetic connection is disconnected and the alarm sounds an alarm. Specifically, the alarm sounds an alarm in the following ways: sound signal, light signal, image signal, etc.

[0055] like Figure 5 As shown, in order to achieve the above-mentioned objectives, the utility model also provides an assembly device, wherein the assembly device includes a conveying device 100, a flipping device 200 and the above-mentioned height detection device, the conveying device 100 is used to convey the product, the flipping device 200 is used to flip the product on the conveying device 100, and the height detection device is arranged on the rear side of the flipping device 200 along the transmission direction of the conveying device 100.

[0056] Specifically, the alarm in the height detection device is communicated with the conveying device and the flipping device respectively. When the alarm determines that the position of the baffle 21 has changed, the alarm sounds an alarm and simultaneously sends a stop signal to the conveying device and the flipping device, so that the conveying device and the flipping device stop running, and the staff has enough time to correct the incorrectly placed products.

[0057] In the description of this utility model, "front" and "rear" are defined according to the transmission direction, and the product is transmitted from front to rear.
