[0031] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0032] like Figure 1 As shown, the embodiment of the utility model first provides a dispensing glue device for chip substrates (chip substrates include carriers, boats, substrates, PCBs, lead frames, wafers, etc.), which mainly includes a support table 1, a gantry 2 installed above the support table 1, and a dispensing glue execution unit 3 installed on the gantry 2; the support table 1 includes a connecting beam 101 and a supporting seat 102 integrally formed at both ends of the connecting beam 101. Such a design enables the support table 1 to have sufficient strength while being lightweight, and also reduces the assembly process;

[0033] A main motion track 12 is installed on the top surface of each support seat 102, and auxiliary motion tracks 14 are installed on the outer side surfaces of the two support seats 102 facing away from each other.

[0034] The gantry 2 includes a frame beam 21 and guide rail seats 22 connected to both ends of the frame beam 21. Each guide rail seat 22 has a top plate 221 and a side plate 222 vertically connected to one side of the bottom surface of the top plate 221, that is, the gantry 2 forms a gantry structure;

[0035] The bottom surface of the top plate 221 is installed and matched with the main motion track 12 on the top surface of the support seat 102, so that the main motion track 12 carries the gantry 2 and can guide the gantry 2 to slide along the main motion track 12;

[0036] The inner sides of the side plates 222 of the two guide rail seats 22 facing each other are installed and matched with the auxiliary motion rails 14 on the two support seats 102, so that the gantry 2 is clamped on both sides of the support platform 1 and guides the gantry to slide;

[0037] The outer side surfaces of the two support seats 102 facing each other are respectively installed with first linear sliding modules 15 to drive the gantry 2 to move along the main motion track 12 , so that the dispensing glue execution unit 3 has two-axis linear motion freedom.

[0038] Compared with the cantilever structure in the prior art, the gantry structure of the gantry 2 avoids the vibration of the end, and indirectly improves the movement accuracy of the dispensing glue execution unit 2; in addition, both sides of the gantry 2 are driven by the first linear sliding module 15 at the same time, which further improves the movement smoothness of the gantry 2, thereby improving the operation accuracy of the dispensing glue execution unit. In addition, the gantry design obviously also increases the working range of the dispensing glue.

[0039] Combination Figure 1-5 The utility model embodiment also provides a gantry drive module, the gantry drive module includes Figure 1 The support platform 1 and the gantry 2 shown in the figure clearly indicate that the gantry drive module can also be applied to other devices that have high requirements on the smoothness of the drive module.

[0040] The support seat 102 specifically includes a vertical plate and a horizontal plate 1022 integrally connected to one side of the bottom end of the vertical plate 1021, and the cross-section of the support seat 102 is L-shaped; the main motion track 12 is installed on the top surface of the vertical plate 1021, and the auxiliary motion track 14 is installed on the outer side of the vertical plate 1021, and the main motion track 12 and the auxiliary motion track 14 both extend along the length direction of the vertical plate; the preferred matching method between the horizontal plate 1022 and the support seat 102 is to open a fixing hole on the surface of the horizontal plate 1022 for the insertion of a fixing pin, so as to fix the support seat 102 on an external work platform, the ground or other installation carrier, so as to realize the installation and fixation of the support seat 102 (the fixing hole and the fixing pin top are solutions that can be easily thought of by technical personnel in this field, and can be directly implemented, so they are not specifically illustrated and marked here).

[0041] Regarding the cooperation mode between the top plate 221 and the main motion track 12, as well as the cooperation mode between the side plate 222 and the auxiliary motion track, in a preferred embodiment of the present utility model, the main motion track 12 includes a first slide rail 121 located on the upper part of the support seat 102, and a first slider 122 is slidably installed on the first slide rail 121, and the first slider 122 is fixedly connected to the gantry 2; the auxiliary motion track 14 includes a second slide rail 141 respectively installed upright on both sides of the support seat 102, and a second slider 142 is slidably installed on the second slide rail 141, and the second slider 142 is fixedly connected to the gantry 2.

[0042] In another embodiment, a main guide groove is directly opened on the bottom surface of the top plate 221 for cooperation with the main motion track 12 on the top surface of the support seat 102, and auxiliary guide grooves are respectively opened on the inner side surfaces facing each other of the side plates 222 of the two guide rail seats 22 for cooperation with the auxiliary motion tracks 14 on the two support seats 102 (the main guide groove and the auxiliary guide groove are not preferred embodiments and are solutions that can be easily thought of by technical personnel in this field, so they are not shown in the accompanying drawings).

[0043] In summary, the sliding of the gantry 2 on the support platform 1 is assisted by four sets of motion tracks, among which the two sets of main motion tracks 12 on the upper part of the support platform need to bear the weight of the gantry 2 and other components installed on the gantry 2, and play a supporting and guiding role; and the auxiliary motion tracks 14 on both sides of the support platform 1 can provide lateral support (the plane where the auxiliary motion tracks are located is perpendicular to the plane where the main motion tracks are located), mainly to provide guidance and restriction for the movement of the gantry 2, to avoid the deflection of the gantry 2 caused by the motion speed error on both sides of the gantry 2 during the movement of the gantry 2, the existence of the auxiliary motion track, i.e. the second slide rail 14, also reduces the deformation of the gantry 2 and the support platform 1 that may be caused by the normal force of the motor during the driving process of the first linear sliding module 15.

[0044] As a preferred improved embodiment, elastic buffers 13 are installed on both sides of the support platform 1, which are used to constrain the starting and ending positions of the movement of the gantry 2. At the same time, the elasticity of the buffers 13 can also reduce the collision between the gantry 2 and the support platform 1, thereby improving the durability of the gantry drive module.

[0045] A third slide rail 211 is installed horizontally in front of the frame beam 21. Obviously, the third slide rail 211 should be perpendicular to the aforementioned main motion track 12 and auxiliary motion track 14. A third slider 2111 is installed on the third slide rail 211. The third slider 2111 is used to carry and install the end effector. A second linear sliding module 212 is also installed horizontally in front of the frame beam 21.

[0046] In the above-mentioned embodiment of the glue dispensing device for chip substrate provided by the utility model, the end effector is the glue dispensing execution unit 3. Considering the diversity of the motion trajectory of the glue dispensing, such as Figure 6As shown, the glue dot execution unit 3 includes a driving seat 31, a lifting member 32 and a glue dot head 31. The driving seat 31 drives the lifting member 32 to move vertically. The driving seat 31 is installed on the frame beam 21, and the glue dot head 31 is installed on the lifting member 32; therefore, the glue dot head 31 has three-axis linear motion freedom.

[0047] The glue dispensing device for chip substrates provided by the utility model reduces the vibration during the movement of the driving module and improves the movement smoothness of the driving module by improving the structure of the driving module carrying the glue dispensing execution unit, thereby improving the operation accuracy of the glue dispensing execution unit and increasing the working range of the glue dispensing.

[0048] The above-mentioned embodiments only express the implementation methods of the utility model, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
