[0002] In order to ensure the sealing between electronic components, existing electronic devices generally have a layer of adhesive between two electronic components. The adhesive can not only fix the adhesive but also seal it. There are many types of adhesives, which are generally divided into two types according to the pressing conditions. The first type is cold-pressed adhesive, which does not need to be heated and can be directly attached between two electronic components. The second type is hot-pressed adhesive, which needs to be heated after the adhesive is attached. The adhesive is hot-melted and then solidified. Hot-melt adhesive has stronger adhesion than cold-pressed adhesive.

[0003] Whether it is cold pressing or hot pressing, it is necessary to apply downward pressure to the electronic components during the bonding process to make the two fit more firmly.

DETAILED DESCRIPTION

[0020] The utility model is further described in conjunction with the following embodiments.

[0021] A specific implementation of a cold pressing mechanism for adhesive bonding of the utility model is as follows: Figure 1 As shown, it includes a bottom plate 1, and a gantry frame 2 is fixedly installed on the top surface of the bottom plate 1. Optionally, the gantry frame 2 includes a top plate 21 and a pair of columns 22, and the pair of columns 22 are respectively fixedly installed on the left side and the right side of the top plate 21, and the bottom end of each column 22 is fixedly connected to the bottom plate 1. The function of the gantry frame 2 is to provide sufficient installation space for the first cylinder 31 and the second cylinder 32 below to be installed.

[0022] Combination Figure 2 A first cylinder 31 is fixedly mounted on the top surface (top plate 21) of the gantry frame 2, a first mounting plate 41 is provided below the bottom surface of the gantry frame 2, and a telescopic rod of the first cylinder 31 passes through the top surface of the gantry frame 2 and is fixedly connected to the first mounting plate 41.

[0023] In order to improve the flow degree and the quality of lamination during lamination, a plurality of first guide columns 81 are provided between the top plate 21 and the first mounting plate 41, and a plurality of second guide columns 81 are arranged at intervals on the first mounting plate 41. The top plate 21 is provided with a plurality of first through holes arranged at intervals for the first guide columns 81 to pass through, and a plurality of first sleeves 91 arranged at intervals are also provided on the top surface of the top plate 21. The first sleeves 91 play the role of extending the guide. Each first sleeve 91 is fixedly installed above the corresponding first through hole. In the assembled state, one end of the first guide column 81 is fixedly connected to the first mounting plate 41, and the other end passes through the first through hole and is inserted into the corresponding first sleeve 91. During the lamination process, the cooperation between the first guide rod and the first sleeve 91 can guide the downward movement path of the first mounting plate 41 to ensure that the first mounting plate 41 will not be offset.

[0024] As an improvement, a driving assembly located in the gantry frame 2 is also fixedly mounted on the top surface of the bottom plate, and the driving assembly includes a first slide 61 and a driver 6 for driving the first slide 61 to slide back and forth in the horizontal direction. Optionally, the driver 6 is a rodless cylinder, and the model of the rodless cylinder is RMT-20X400. The first slide 61 is essentially the working end of the rodless cylinder, and the first slide 61 can be driven to slide back and forth in the horizontal direction through external pneumatic control.

[0025] The top surface of the first slide 61 is fixedly mounted with a mounting bracket 5, which is a rectangular structure and is provided with a third mounting plate 43 located on its top surface. The second cylinder 32 is fixedly mounted inside the mounting bracket 5 (on the bottom surface of the third mounting plate 43), and a second mounting plate 42 is further provided above the top surface of the mounting bracket 5. The telescopic rod of the second cylinder 32 passes through the top surface of the mounting bracket 5 (the third mounting plate 43) and is fixedly connected to the second mounting plate 42.

[0026] In order to improve the flow degree and the quality of the pressing, a plurality of second guide posts 82 are provided between the third mounting plate 43 and the second mounting plate 42, and the plurality of second guide posts 82 are arranged at intervals on the second mounting plate 42; the third mounting plate 43 is provided with a plurality of second through holes arranged at intervals for the second guide posts 82 to pass through, and the bottom end surface of the third mounting plate 43 is also provided with a plurality of second sleeves 92 arranged at intervals, each second sleeve 92 is fixedly installed under the corresponding second through hole, and in the assembled state, one end of the second guide post 82 is fixedly connected to the second mounting plate 42, and the other end passes through the second through hole and is inserted into the corresponding second sleeve 92. During the pressing process, the cooperation between the second guide rod and the second sleeve 92 can guide the upward movement path of the second mounting plate 42 to ensure that the second mounting plate 42 will not deviate.

[0027] It should be noted that the bottom surface of the first mounting plate 41 can be fixedly connected to a template or insert for pressing, or directly used as a mold (applicable to products with planar structures). Similarly, the top surface of the second mounting plate 42 can be fixedly connected to a template or insert for pressing, or directly used as a mold.

[0028] In order to reduce the load of the first slide 61 and avoid affecting the service life of the driver 6 due to excessive pressure on the first slide 61, a second slide 71 is fixedly installed on the bottom surface of the mounting bracket 5. The bottom end of the second slide 71 is provided with a slide rail 72 that slides with the second slide 71, and the slide rail 72 is fixedly installed on the bottom plate 1. Optionally, the second slide 71 is located on the left side of the bottom surface of the mounting bracket 5, and the first slide 61 is located on the right side of the bottom surface of the mounting bracket 5. In this way, the first slide 61 and the second slide 71 act as a support together, thereby preventing the driver 6 from being overloaded.

[0029] A cold pressing mechanism for adhesive bonding in this embodiment drives the second mounting plate 42 to slide in the horizontal direction by setting a driver 6, so that the second mounting plate 42 can support the product to move between various stations, which solves the problem of inconvenience in use in the past, has a simple and compact structure, and improves the degree of automation of the cold pressing mechanism. The cold pressing mechanism is provided with a first cylinder 31 and a second cylinder 32. The first cylinder 31 drives the first mounting plate 41 to move downward to pressurize the product, and the second cylinder 32 drives the second mounting plate 42 to move upward to pressurize the product. This two-way pressurization structure can better fit the adhesive to the product, thereby improving the laminating quality of the product.
