[0023] Example: Figure 1-5As shown, a product pressure-holding mechanism includes a mounting base 10 and a lifting drive unit 20 mounted on the mounting base 10. A horizontal drive unit 30 is mounted on the lifting drive unit 20, and a pressure-holding unit 40 is mounted on the horizontal drive unit 30. The lifting drive unit 20 can drive the horizontal drive unit 30 and the pressure-holding unit 40 to move up and down, and the horizontal drive unit 30 can drive the pressure-holding unit 40 to move horizontally. The pressure-holding unit 40 includes a base 41 and a pressure-holding head 48. The pressure-holding head 48 is slidably mounted on the base 41, and a pressure sensor 49 is fixedly mounted on the base 41. A spring 45 is installed between the pressure-holding head 48 and the pressure sensor 49.
[0024] This application utilizes a software control system to control the operation of the lifting drive unit 20 and the horizontal drive unit 30. The lifting drive unit 20 adjusts the vertical position of the pressure holding head 48 to ensure it contacts the product. The horizontal drive unit 30 fine-tunes the horizontal position of the pressure holding head 48 to apply a certain pressure to the product, thus completing the automatic pressure holding operation. This application adjusts the pressure holding force by changing the spring compression. A pressure sensor records the pressure holding force in real time. The software control system controls the stroke of the horizontal drive unit 30 based on the pressure feedback from the pressure sensor, ensuring adjustable pressure during the product pressure holding process. Once the pressure holding head reaches a preset value, the software control system starts timing. After the preset time is reached, the pressure holding head leaves the product. Therefore, this application achieves flexible adjustability of the pressure holding force and controllable pressure holding time through the cooperation of the software control system, the horizontal drive unit 30, and the pressure holding unit 40, thereby meeting the pressure holding requirements of products under different conditions. It features a short testing cycle, strong operability, low cost, and promotes the development process of new products.
[0025] like Figure 1 As shown, the lifting drive unit includes a servo motor 21 and a lead screw module 22 connected to the servo motor 21. The horizontal drive unit 30 is mounted on the lead screw module 22 via a support plate 23. The servo motor 21 can drive the support plate 23 to move up and down along the lead screw module 22.
[0026] The lead screw module 22 is arranged vertically along the mounting base 10, and a photoelectric sensor 11 is fixedly mounted on the mounting base 10. The photoelectric sensor 11 is used to detect whether the product is in position. The servo motor 21 drives the lead screw module 22 to run, and the lead screw module 22 drives the support plate 23 and the horizontal drive unit 30 to move up and down along the lead screw module 22. The height of the pressure holding head 48 is adjusted by using the servo motor 21 and the lead screw module 22, which improves the stability and accuracy of the operation of the pressure holding head 48.
[0027] like Figure 1 and Figure 4 As shown, the horizontal drive unit 30 includes a miniature electric cylinder 31 and a slide plate 32 connected to the miniature electric cylinder 31. The pressure holding unit 40 is mounted on the slide plate 32, and the miniature electric cylinder 31 can drive the pressure holding unit 40 to move horizontally. The miniature electric cylinder 31 is horizontally mounted on the support plate 23. When the miniature electric cylinder 31 extends or retracts, it can drive the pressure holding unit 40 on the support plate 23 to move horizontally to maintain pressure on the product.
[0028] like Figure 1-3 As shown, the base 41 is provided with a slide rail 42 and a fixing block 44. The pressure holding head 48 is slidably mounted on the slide rail 42, the pressure sensor 49 is installed in the fixing block 44, and the spring 45 is placed in the fixing block 44.
[0029] The pressure-holding unit 40 further includes a connecting block 46 and a support block 47 fixedly connected to the connecting block 46. The pressure-holding head 48 is fixedly installed on the support block 47. The connecting block 46 is slidably installed on the slide rail 42 via a slider 43. The first end of the spring 45 contacts the support block 47, and the second end of the spring 45 contacts the pressure sensor 49. The first end of the spring 45 directly contacts the support block 47, or indirectly contacts the support block 47 through an intermediate component. The second end of the spring 45 directly contacts the pressure sensor 49, or indirectly contacts the pressure sensor 49 through an intermediate component. The slide rail 42 is horizontally arranged on the upper surface of the base 41. The slider 43 is slidably mounted on the slide rail 42. The connecting block 46 is fixed on the slider 43 and is located between the fixed block 44 and the support block 47. The pressure holding head 48 is installed on the side of the support block 47 away from the connecting block 46. A spring 45 is provided between the connecting block 46 and the pressure sensor 49. When the micro electric cylinder 31 drives the pressure holding head 48 to contact the product, the spring 45 is compressed and transmits the pressure to the pressure sensor 49. The pressure holding pressure is adjusted by changing the amount of compression of the spring 45. Therefore, compared with the traditional pressure holding device that adjusts the pressure holding by adjusting the counterweights of different weights, this application is more convenient and faster, and the pressure holding is more controllable.
[0030] Optionally, the base 41 is provided with two parallel slide rails 42, the slide rails 42 are arranged horizontally on the base 41, and the pressure holding head 48 is installed vertically on the support block 47.
[0031] like Figure 3 As shown, the first end of the pressure-holding head 48 is fixedly installed on the support block 47, the second end of the pressure-holding head 48 is a free end, and the second end of the pressure-holding head 48 protrudes from the base 41. The second end of the pressure-holding head 48 is provided with a bevel. The bevel facilitates product fixation.
[0032] The operation method of this application includes the following steps:
[0033] Step 1: When the carrier carrying the product is transported to the pressure holding station, the photoelectric sensor 11 senses that the product has arrived, where the product is a mobile phone frame with foam installed;
[0034] Step 2: The software control system controls the servo motor 21 to move the pressure holding head 48 to the preset position;
[0035] Step 3: The software control system controls the micro electric cylinder 31 to drive the pressure holding head 48 to press the product, and adjusts the position of the pressure holding head 48 according to the pressure value detected by the pressure sensor 49;
[0036] Step 4: When the pressure value reaches the preset value, the software control system starts timing until the preset pressure holding time is reached. Then, the miniature electric cylinder 31 drives the pressure holding head 48 to leave the product, and the pressure holding test ends.
[0037] It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be determined by the appended claims.
