Maximum distance is defined, and can be convenient for controlling the turnning circle of motor 12 by setting pulse signal, and then control mounting plate
24 to mounting groove 11a move distance, and then ensure that the bullet needle on collection plate component 200 gives the electricity on electrode card component 300
The precompressed amount of pole meets sets requirement.
It should be noted that the present embodiment sliding rail 13 can be arranged as required to one, three or more, and support arm
111, fixed frame 142 and sliding block 21 are arranged in a one-to-one correspondence with it, and interconnecting piece 242 each connects then than sliding rail 13 few one
Socket part 242 is respectively positioned between two neighboring sliding rail 13, and is connected to the phase of two neighboring fixed frame 142 and support arm 111 respectively
Offside.
In practical applications, due to collection plate component 200 sensitivity and precise requirements it is very high, therefore need regular
To the progress self-test of collection plate component 200, collection plate component 200 plays needle and the electrode on electrode card component 300 in process of self-test
Point needs to carry out self-test to the collecting unit on collection plate component 200 again after disconnecting, collection plate component 200 and electricity after the completion of self-test
Pole card 300 needs then be electrically connected when test job, as shown in Figure 1, it is the bullet needle and electrode of collection plate component 200
Schematic diagram under the electrode points connection status of card component 300, as shown in Fig. 2, it is the bullet needle and electrode card of collection plate component 200
Schematic diagram under the electrode points discrete state of component 200；Due to signal acquisition process be hit by a bullet needle precompressed accuracy of measurement it is higher, generally
For 1.8 ± 0.2mm, therefore in order to avoid causing to play needle damage or scratching electrode card playing needle and overvoltage in electrode card contact process
The contact point of component 300 needs to accurately control the precompressed amount that needle gives electrode points that plays；In addition, if precompressed amount is insufficient, bullet can be influenced
The connection reliability of needle and electrode card component electrode points.It should be noted that the precompressed amount for playing needle is not fixed, with bullet
The material of needle is related to length.
And in order to improve the control accuracy for playing needle precompressed amount, therefore an inductive component 30 is arranged in the present embodiment, is used for when cunning

When 11a is moved, if the distance between the collection plate component 200 and electrode card component 300 on mounting plate 24 reach setting value, sense
It answers component 30 to generate inductive signal, and the number of turns being rotated further according to above-mentioned inductive signal controllable motor 12, and then controls and adopt
Collect the distance that board group part 200 is moved to electrode card component 300, can guarantee that the bullet needle of collection plate component 200 is inserted into electrode card group
Precision on part 300, and then ensure to play needle and give the precompressed amounts of electrode points and meet setting value.It is understood that 12 turns of motor
Setting relationship between the dynamic number of turns and distance is generally preset according to selected motor type and rotating speed.Wherein, originally
Inductive component 30 described in embodiment includes that a light sensation inductor 31 and one being set on the mounting plate ontology 141 is set to the cunning
Block connecting plate 22 and the anti-dazzling screen 32 that the optical signal for blocking the light sensation inductor 31 can be moved to, i.e., when sliding block 21 is along sliding rail
13 to mounting plate ontology 141 when moving, and collection plate component 200 and anti-dazzling screen 32 move synchronously, and when anti-dazzling screen 32 shelters from light
When the electric signal of propagated sensation sensor, the distance between collection plate component 200 and electrode card component 300 are setting value, therefore can obtained
Drive motor 12 is rotated further the setting number of turns when above electrical signal, and then collection plate component 200 after the rotation setting number of turns of motor 12
The distance of movement just when above-mentioned setting value, set precompressed amount to make the bullet needle of collection plate component 200 just give electrode electricity.
It is understood that the inductive component 30 of the present embodiment is not limited to above-mentioned anti-dazzling screen 32 and light sensation inductor 31, arbitrarily can
The inductor of inductive signal is generated when sliding block 21 moves to setting position along the sliding rail 13 can meet wanting for the present embodiment
It asks, such as travel switch.
Specific embodiment of the present utility model described above does not constitute the restriction to scope of protection of the utility model.
The various other corresponding changes and deformation that any technical concept according to the present utility model is made, should be included in this practicality
In novel scope of the claims.
