Description

Technical Field

[0001] The invention relates to the technical field of rubber strip installation, in particular to an insertion feeding mechanism. Background Art

[0002] During the installation of the rubber strips of the door panels, the traditional installation method is manual assembly, but due to the low assembly efficiency, the production efficiency of the entire production line is affected, and the installation accuracy is not high enough.

[0003] For this reason, some mechanical installation processes have emerged to achieve automated operation of the rubber strips. This installation method is to press the rubber strips into the grooves by squeezing them when they are delivered to the grooves of the door panels. However, this method can only be used to install rubber strips for grooves that are small inside and large outside, and cannot be used for grooves that are large inside and small outside or of different shapes; and after the installation is completed and the squeezing force is removed, some of the rubber strips will retreat outward.

[0004] Based on this, our company has designed a new process that is very different from ordinary installation, which allows the rubber strip to be installed by insertion, which can effectively solve the above problems. At the same time, a whole set of new rubber strip installation equipment is designed to match it, and this solution is the traction structure part of it.

[0005] In the equipment for press-in rubber strip installation, there is also a traction structure, and the wheels on it only play a simple guiding role and cannot meet the requirements of plug-in installation. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an insertion feeding mechanism which has high versatility, synchronous adjustment, ensures the fullness of the rubber strip, avoids deformation of the tail section of the rubber strip, can adjust the clamping force, and realizes plug-in installation.

[0007] The purpose of the present invention is achieved through the following technical solutions: The insertion feeding mechanism comprises:

[0008] A guide wheel group formed by an upper guide wheel and a lower guide wheel is arranged on an inverted T-shaped plate, and the inverted T-shaped plate is slidably arranged on a supporting frame through a telescopic cylinder to form a structure for limiting the upper and lower positions of the rubber strip;

[0009] A traction wheel group is formed by a traction driving wheel and a traction driven wheel, wherein the traction driven wheel is mounted on an inverted T-shaped plate through an ear seat plate, and the traction driving wheel is mounted on an L-shaped support plate, and the L-shaped support plate is fixed on a support frame;

[0010] A strip plate is installed at the upper end of the vertical base plate through an adjusting bolt A, and the upper guide wheel is installed on the strip plate; a lug seat plate is fixed on the strip plate, and the traction driven wheel is hinged on the lug seat plate;

[0011] The strip plate, the adjusting bolt A and the upper guide wheel form a height adjusting mechanism, and the traction driven wheel and the ear seat plate form an angle adjusting mechanism.

[0012] Furthermore, the angle adjustment mechanism also includes a rotating block, which has a U-shaped notch, and a traction driven wheel is installed in the U-shaped notch; the rotating block is hinged to the ear seat plate through front and rear rotating pins; the rotating block is penetrated by an adjusting bolt B in the up and down directions, and the adjusting bolt B is threadedly matched with the ear seat plate so as to be able to be twisted.

[0013] Furthermore, it also includes a placement structure, which includes an external support structure and an internal support structure; the external support structure includes a bracket groove, the bracket groove has an opening facing upward, and a rubber strip is placed in the groove; the internal support structure includes a rigid core, the rigid core is passed through the rubber strip and one end of the rigid core extends out of the rubber strip.

[0014] Furthermore, the rubber strip extends out of the bracket groove, and the extended end of the rubber strip is located between the bracket groove and the extended end of the rigid core.

[0015] Furthermore, it also includes a lateral clamping structure, which includes a tightening mechanism and a pressing mechanism; it includes a telescopic cylinder and an inverted T-shaped plate, the telescopic cylinder is connected to the base, the base is slidably arranged on the support frame, the inverted T-shaped plate is fixed on the base, and the inverted T-shaped plate is installed with a guide wheel group; the pressing mechanism includes a pressing cam and a rotating shaft, the rotating shaft is vertically arranged and the upper end thereof is installed with a pressing cam and the lower end thereof is installed with a lockable rotating disk, and the pressing cam is against the front side of the rubber strip to achieve clamping in the front and rear directions.

[0016] Furthermore, the turntable is coaxially mounted on a turntable base through bolts, and the turntable base is drivingly connected to an output end of a self-locking steering motor.

[0017] Furthermore, an auxiliary wheel is provided at the front side of the rubber strip through a vertical plate, and the auxiliary wheel limits the rubber strip from the front side; the traction wheel group limits the rubber strip in the front and rear directions at the traction position, and the traction wheel group and the auxiliary wheel also limit the rubber strip in the front and rear directions.

[0018] Furthermore, the cross section of the rubber strip is C-shaped and the opening faces forward; the pressing cam directly rests on the rigid core.

[0019] The present invention has the following advantages:

[0020] (1) By setting the height adjustment mechanism and the angle adjustment mechanism, the rubber strip can be adaptively adjusted according to the model; and when adjusting the height, only the strip plate needs to be adjusted to achieve the adjustment of the upper guide wheel and the driven traction wheel together, and the two can act together, which is convenient;

[0021] (2) By setting up external and internal support structures, the fullness of the rubber strip during installation is ensured, and deformation that makes it impossible to install is avoided, so smooth installation can be achieved;

[0022] (3) The setting of the tightening mechanism and the pressing mechanism is not only to make the rubber strip close to the rigid core, but also to clamp the left end of the rubber strip to form a front-to-back limit when the left end of the rubber strip is separated from the bracket groove, so that the rubber strip cannot be tightened on the outside. This prevents the rubber strip from deforming in the front-to-back direction, and enables the tail end of the rubber strip to be smoothly inserted into the door panel groove;

[0023] (4) The arrangement of the clamping cam, the rotating shaft and the self-locking steering motor can adjust the clamping force by rotating the clamping cam according to actual conditions, and the adjustment is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0029] like Figure 1~Figure 3 As shown, the insertion feeding mechanism includes a guide wheel group, a traction wheel group, a pressing cam 5 and an auxiliary wheel 32; wherein the guide wheel group is arranged on the front side of the inverted T-shaped plate 14, and includes an upper guide wheel 22 and a lower guide wheel 24; the traction wheel group includes a traction driving wheel 25 and a traction driven wheel 26, and the traction driven wheel 26 is arranged on the inverted T-shaped plate 14 through a rotating member 30, and the traction driving wheel 25 is arranged on the L-shaped support plate 10. The inverted T-shaped plate 14 and the L-shaped support plate 10 are both installed on the support frame 11.

[0030] In this solution, there are two sets of balanced forces, each of which applies forces from the top and bottom, front and back directions:

[0031] The first group, at the guide position, the guide wheel group applies force to the rubber strip 2 from the top and bottom directions; the friction force formed by the guide wheel group in the front and rear directions and the clamping cam 5 apply force in the front and rear directions.

[0032] The second group, at the traction position, the traction wheel group applies force to the rubber strip 2 from the top and bottom directions; the friction force formed by the traction wheel group in the front and rear risks and the auxiliary wheel 32 apply force in the front and rear directions.

[0033] In this solution, the inverted T-shaped plate 14 is fixed on the base, the base is slidably arranged on the support frame 11 along the front-back direction, and the base is drivingly connected to the telescopic cylinder 4.

[0034] At the upper edge of the inverted T-plate 14, a strip plate 28 is installed through an adjusting bolt A27, and the upper guide wheel 23 is installed on the strip plate 28, forming a mechanism in which the upper guide wheel 23 and the lower guide wheel 24 can be adjusted in height.

[0035] In addition, an ear seat plate 29 is fixed on the front side of the strip plate 28, and the ear seat plate 29 is hinged to the rotating block 30 through a rotating pin arranged in the front-back direction; the traction driven wheel 26 is installed on the rotating member 30, and the rotating member 30 has a U-shaped notch, and a screw cap is provided at the U-shaped notch, and the screw cap is threadedly matched with the upper end of the adjusting bolt B31, and the lower end of the adjusting bolt B31 is hinged to the hinge seat, and the hinge seat is fixed to the T-shaped plate 14 to form an angle adjustment mechanism. When the screw cap is turned, the rotating member 30 can be rotated, thereby pressing downward.

[0036] In this solution, the rubber strip 2 is placed in the placement structure, the cross-section of the rubber strip 2 is C-shaped and the opening faces forward; the placement structure includes an external support structure and an internal support structure, both of which install the rubber strip 2 from the inside and outside; it also includes a lateral clamping structure, which clamps and installs the rubber strip 2 from the front and back.

[0037] The outer support structure includes a bracket slot 1, the slot of which faces upwards, and the rubber strip 2 is inserted into the slot. The inner support structure includes a rigid core 3, which is inserted into the rubber strip 2 to keep the rubber strip 2 full.

[0038] When installing the external and internal support structures, Figure 1 As shown: the right end of the rubber strip 2 extends out of the right end of the bracket slot 1, and the right end of the rigid core 3 extends out of the right end of the rubber strip 2. The bracket slot 1 only serves to support, and the rubber strip 2 extends out to facilitate installation in the slot of the door panel; the rigid core 3 extends out to facilitate subsequent extraction from the rubber strip 2.

[0039] In this solution, since the rigid core 3 only plays an internal supporting role and needs to be pulled out after installation, there is a clearance fit between the rigid core 3 and the rubber strip 2.

[0040] As for the lateral clamping structure, it is arranged at the protruding end of the rubber strip 2, and includes a tightening mechanism and a pressing mechanism.

[0041] Specifically, the clamping mechanism is a side structure formed by a guide wheel set, an inverted T-shaped plate 14 , and a telescopic cylinder 4 .

[0042] The pressing mechanism includes a pressing cam 5 and a rotating shaft 6. The rotating shaft 6 is vertically arranged, and a pressing cam 5 is installed on the upper end of the rotating shaft 6. The pressing cam 5 is located in a horizontal plane and presses the rubber strip 2 from the front. When the rotating shaft 6 is rotated, the pressing cam 5 can adjust the pressing force on the rubber strip 2.

[0043] In this embodiment, a rotating disk 7 is provided at the lower end of the rotating shaft 6, and the rotating disk 7 is coaxially mounted on the disk seat 8 by bolts, and the output end of the self-locking steering motor 9 is meshed with the disk seat 8 through a gear. The rotation adjustment of the pressing cam 5 is realized by the self-locking steering motor 9.

[0044] When the clamping cam 5 rotates, the position of the clamping point will change in the front-rear direction, so the telescopic cylinder 4 will drive the position of the traction wheel group in the front-rear direction to change adaptively.

[0045] The above embodiments only express preferred implementation modes, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. 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 present invention, and these all belong to the protection scope of the present invention.
