[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0018] like Figure 1-2As shown, a movable gluing platform comprises a platform body 1 and a glue storage rack 2 movably arranged on the platform body 1, a first groove 11 and a second groove 12 are arranged on the top surface of the platform body 1, the depth of the first groove 11 is greater than the depth of the second groove 12, the depth of the flux in the groove can be changed by the depth of the groove, and thus it can be suitable for bumps of different specifications, an oil storage tank is arranged on the glue storage rack 2, the bottom of the oil storage tank is arranged with an opening 211, the opening 211 can move with the glue storage rack 2, when the opening 211 is located directly above the first groove 11, the oil storage tank is connected with the first groove 11, when the opening 211 is located directly above the second groove 12, the oil storage tank is connected with the second groove 12, when it is connected with the first groove 11 or the second groove 12, flux can be added to the first groove 11 or the second groove 12, the addition is more convenient and the cost is lower.
[0019] In this embodiment, a third groove 13 and a fourth groove 14 are further provided on the top surface of the platform body 1. The depth of the third groove 13 is less than the depth of the second groove 12, and the depth of the fourth groove 14 is less than the depth of the third groove 13. That is, in this embodiment, the adhesive platform can be suitable for four different specifications of protrusions. Of course, more grooves can be provided, such as a fifth groove, a sixth groove, etc., to further increase its applicability, which should not exceed the scope of the record of this application.
