It is the top view of supporting block and idler wheel shown in Fig. 5.As viewed in figures 5-8, supporting block 13 includes base portion 15, and base portion 15 is at least partly
It extends in the groove 11 of guide rail 3.Supporting block 13 further includes the support portion 17 upwardly extended from base portion 15, and support portion 17 is for solid
Determine door-plate (not shown) and end of door plate plays a supportive role.Define hole 19 in support portion 17, screw can be passed through by it and
Door-plate is fixed in supporting block.For the ease of the support and installation of door-plate, support portion 17 is preferably at L-shaped.In preferred embodiment
In, base portion 15 is integrally formed with support portion 17, it will be appreciated that, they can be separately formed and be connected by known
The mode of connecing is joined together.
According to the present invention, roll wheel assembly 1 includes at least one first idler wheel 21 being installed on the base portion 15 of supporting block 13,
First idler wheel 21 with the connection wall 9 of guide rail 3 for contacting and rolling in connection wall 9.Preferably, roll wheel assembly 1 includes vertical
At least two first idler wheels 21 on base portion 15 for being installed to supporting block 13 at interval to (that is, along rail length direction).
First idler wheel 21 defines the first idler wheel principal plane, that is, the plane vertical with the rolling axis of the first idler wheel 21.Roll wheel assembly 1
It further include at least one second idler wheel 23 being installed on the base portion 15 of supporting block 13.Similarly, the second idler wheel 23 also defines
Second idler wheel principal plane, that is, the plane vertical with the rolling axis of the second idler wheel 23.Second idler wheel 23 is mounted so that second
Idler wheel principal plane is vertical with the first idler wheel principal plane, so that the first side wall 5 and second sidewall of the second idler wheel 23 and guide rail 3
7 contact and abut against the first side wall 5 and the rolling of second sidewall 7.Although the second idler wheel 23 can be with along 3 longitudinal direction of guide rail
First idler wheel 21 is mounted on same position and is located at 21 top of the first idler wheel, but preferably makes the second idler wheel 23 and at least one
First idler wheel, 21 longitudinal gap is installed on the base portion 15 of supporting block 13 with opening.By at least one first idler wheel 21 and at least
One the second idler wheel 23, and make the second idler wheel principal plane vertical with the first idler wheel principal plane, at least one second idler wheel 23
It is mobile that supporting block 13 can not only be guided, and supporting block 13 can be limited on the direction vertical with the first idler wheel principal plane
Position prevents supporting block from offset occur and then frictional impact occurs with guide rail.
Preferably, roll wheel assembly 1 includes at least two second idler wheels 23, and along the longitudinal direction (guide rail of supporting block
Length direction) idler wheel that is arranged near two ends of supporting block is the second idler wheel 23 respectively.For example it is assumed that in supporting block 13
Installation there are two the second idler wheel 23, then the first all idler wheels 21 along it is longitudinal be substantially all disposed within two the second idler wheels 23 it
Between.By the way that two the second idler wheels 23 contacted with the first side wall 5 of guide rail 3 and second sidewall 7 are separately positioned on supporting block 13
Near end, supporting block 13 can be limited to the maximum extent and is shifted around the centre of supporting block 13 relative to guide rail 3,
And then frictional impact occurs with guide rail 3.
Fig. 5-8 is shown according to a preferred embodiment of the present invention.As viewed in figures 5-8, it is equipped in supporting block 13
Two the second idler wheels 23, they are configured to contact with the first side wall 5 of guide rail 3 and second sidewall 7, for the company with guide rail 3
The first idler wheel 21 for connecing the contact of wall 9 is arranged between two the second idler wheels 23 along the longitudinal direction of supporting block 13.For the ease of
The installation of second idler wheel 23 can be provided on the base portion 15 of supporting block 13 and penetrate chamber 25, and each second idler wheel 23 passes through the
Two pin shafts 27, which are installed in, accordingly to be penetrated in chamber 25 and partly exposes from the both-side opening for penetrating chamber 25, so as to leading
The first side wall 5 and second sidewall 7 of rail 3 contact.
Although the first idler wheel 21 being located between two the second idler wheels 23 and for contacting with the connection wall 9 of guide rail 3 can
Be individually setting and only one or it is multiple, but in the preferred embodiment shown in Fig. 5-8, the first idler wheel 21 is shown as
It is arranged in pairs and there is two pair of first idler wheel 21.Being arranged in pairs in the application refers to installs on same first pin shaft 29
Two the first idler wheels 21.Two the first idler wheels 21 installed on same first pin shaft 29 can both be located at branch as viewed in figures 5-8
The recess towards the connection wall 9 of guide rail 3 can also be arranged in the two sides of the base portion 15 of bracer 13 on the base portion 15 of supporting block 13
(not shown) and two the first idler wheels 21 are mounted in recess.It, can be further by being arranged in pairs the first idler wheel 21
Stability when supporting block 13 is moved along guide rail 3 is improved, supporting block 13 and guide rail 3 is prevented to be in contact collision.
During supporting block 13 is moved along guide rail 3, since operator is firmly excessive, it may occur that supporting block with
And idler wheel is deviate from from guide rail.For this purpose, can the first side wall 5 and second sidewall 7 in guide rail 3 and the side close to connection wall 9
Opposite free side is provided with the protruding portion 31 extended towards to prevent the first idler wheel 21 from deviating from from guide rail 3, two protruding portions 31
Between define the slit 33 passed through for the base portion 15 of supporting block 13 by it.Preferably, protruding portion 31 is dimensioned to make to dash forward
Portion 31 is at least partly contacted with the rolling surface of the first idler wheel 21 out.In this way, can not only prevent the first idler wheel 21 from guide rail 3
Middle abjection, but also can be further improved the stability of the first idler wheel, reduce or eliminate supporting block 13 and/or idler wheel and lead
The probability of the generation frictional impact of rail 3.
Even if frictional impact does not occur for supporting block 13 and/or idler wheel and guide rail 3, but the first idler wheel 21 and the second idler wheel 23 exist
Frictional dissipation can more or less occur when rolling on guide rail 3, this is equally possible to generate some clasts or powder.In order to avoid metal
Clast or powder lead to the short circuit on the rupture of the silicon wafer on chip surface or chip, the first idler wheel 21 and/or the second rolling
Wheel 23 is preferably made of plastics or rubber material.
Above in conjunction with specific embodiments to the present invention have been described in detail.Obviously, above description and show in the accompanying drawings
Embodiment out should be construed as illustratively, but not to limit the present invention.For example, although above be preferably implemented
Example is retouched for roll wheel assembly with the roll wheel assembly for sliding door, in particular for the sliding door of chip testing machine
It states, it will be appreciated that, roll wheel assembly of the invention is not limited to use in sliding door, such as roll wheel assembly of the invention can also be used
In various carts.To those skilled in the art, it can carried out respectively without departing from the spirit of the invention
Kind variations or modifications, these variations or modifications are all without departing from the scope of the present invention.
